Gamow states are vector states for the pure decaying part of a quantum resonance. We review and analyze the properties of Gamow vectors in different representations. In particular, we discuss the controversial problem of assigning a mean value of the energy for a Gamow state from several points of view. The question on whether a Gamow state is a pure state or not is also analyzed here, as has relevance on the assignation of (...) a non-zero value for the entropy for a Gamow state. (shrink)

In this study, the focus was on the development of green energy and future prediction for the consumption of current energy sources and green energy development using an improved deep learning algorithm. In addition to the analysis of the current energy consumption used for the natural gas and oil as fuel, deep neural network algorithm is used to train the system as well as to process the data obtained previously, ranging from literature from the year 2003 (...) until the year 2019, for consumption of fuel. Also, using the proposed algorithm to predict the development of green energy consumption till 2030 is presented in terms of solar and wind generators. The resulting study also focuses on depletion of energy currently used or pollution caused because of it. The green energy controlling issue can take effect by using multiple layers of handling different features extracted from different sources and then learning the system to control it.This study aims to take advantage of carbon emissions to reduce their impact and dependence in the future on environmentally friendly renewable energies. Predicting the correct and precise amount of energy consumption and increasing the amount of environmentally friendly energy lead to a healthy ecosystem. The expected green energy consumption in the future is almost 78.25 EJ in 2030 and will be, in total energy average, 56% in 2045. The aim is to reduce dependency on costly and environmentally harmful fuels. (shrink)

Hybrid energy storage system has been widely studied as an important technology for electric vehicles. Since the hybrid energy storage system is a nonlinear and complex system, the modeling of the system and the high-precision nonlinear control strategy are technical difficulties for research. The establishment of a high-precision mathematical model of the hybrid energy storage system is the basis for the study of high-quality nonlinear control algorithms. Fortunately, the theory of fractional calculus can help build accurate mathematical (...) models of hybrid energy storage systems. In order to obtain the high-quality nonlinear control strategy of this complex system, this paper, respectively, carried out fractional-order modeling and analysis on the three basic equivalent working states of the hybrid energy storage system of electric vehicles. Among them, the fractional-order average state space model is carried out for the equivalent Buck and Boost mode. Also, the steady-state analysis of the equivalent Dual-Boost mode is carried out by combining the fractional-order calculus theory with the equivalent small parameter variable method. Finally, the effectiveness and precision of the fractional-order model are proved by simulation and experiment. (shrink)

The effects of the vacuum electromagnetic fluctuations and the radiation reaction fields on the time development of a simple microscopic system are identified using a new mathematical method. This is done by studying a charged mechanical oscillator (frequency Ω 0)within the realm of stochastic electrodynamics, where the vacuum plays the role of an energy reservoir. According to our approach, which may be regarded as a simple mathematical exercise, we show how the oscillator Liouville equation is transformed into a Schrödinger-like (...) stochastic equation with a free parameter h′ with dimensions of action. The role of the physical Planck's constant h is introduced only through the zero-point vacuum electromagnetic fields. The perturbative and the exact solutions of the stochastic Schrödinger-like equation are presented for h′>0. The exact solutions for which h′<h are called sub-Heisenberg states. These nonperturbative solutions appear in the form of Gaussian, non-Heisenberg states for which the initial classical uncertainty relation takes the form 〈(δx 2)〉〈(δp) 2 〉=(h′/2) 2,which includes the limit of zero indeterminacy (h → 0). We show how the radiation reaction and the vacuum fields govern the evolution of these non-Heisenberg states in phase space, guaranteeing their decay to the stationary state with average energy hΩ 0 /2 and 〈(δx) 2 〉〈(δp) 2 〉=h 2 /4 at zero temperature. Environmental and thermal effects-are briefly discussed and the connection with similar works within the realm of quantum electrodynamics is also presented. We suggest some other applications of the classical non-Heisenberg states introduced in this paper and we also indicate experiments which might give concrete evidence of these states. (shrink)

We review some results in the theory of non-relativistic quantum unstable systems. We account for the most important definitions of quantum resonances that we identify with unstable quantum systems. Then, we recall the properties and construction of Gamow states as vectors in some extensions of Hilbert spaces, called Rigged Hilbert Spaces. Gamow states account for the purely exponential decaying part of a resonance; the experimental exponential decay for long periods of time physically characterizes a resonance. We (...) briefly discuss one of the most usual models for resonances: the Friedrichs model. Using an algebraic formalism for states and observables, we show that Gamow states cannot be pure states or mixtures from a standard view point. We discuss some additional properties of Gamow states, such as the possibility of obtaining mean values of certain observables on Gamow states. A modification of the time evolution law for the linear space spanned by Gamow shows that some non-commuting observables on this space become commuting for large values of time. We apply Gamow states for a possible explanation of the Loschmidt echo. (shrink)

In the framework of the rigged Hilbert space, unstable quantum systems associated with first-order poles of the analytically continued S-matrix can be described by Gamow vectors which are generalized vectors with exponential decay and a Breit-Wigner energy distribution. This mathematical formalism can be generalized to quasistationary systems associated with higher-order poles of the S-matrix, which leads to a set of Gamow vectors of higher order with a non-exponential time evolution. One can define a state operator from the (...) set of higher-order Gamow vectors which obeys the exponential decay law. We shall discuss to what extent the requirement of an exponential time evolution determines the form of the state operator for a quasistationary microphysical system associated with a higher-order pole of the S-matrix.

We present the Dirac and Laplacian operators on Clifford bundles over space–time, associated to metric compatible linear connections of Cartan–Weyl, with trace-torsion, Q. In the case of nondegenerate metrics, we obtain a theory of generalized Brownian motions whose drift is the metric conjugate of Q. We give the constitutive equations for Q. We find that it contains Maxwell’s equations, characterized by two potentials, an harmonic one which has a zero field (Bohm-Aharonov potential) and a coexact term that generalizes the Hertz (...) potential of Maxwell’s equations in Minkowski space.We develop the theory of the Hertz potential for a general Riemannian manifold. We study the invariant state for the theory, and determine the decomposition of Q in this state which has an invariant Born measure. In addition to the logarithmic potential derivative term, we have the previous Maxwellian potentials normalized by the invariant density. We characterize the time-evolution irreversibility of the Brownian motions generated by the Cartan–Weyl laplacians, in terms of these normalized Maxwell’s potentials. We prove the equivalence of the sourceless Maxwell equation on Minkowski space, and the Dirac-Hestenes equation for a Dirac-Hestenes spinor field written on Minkowski space provided with a Cartan–Weyl connection. If Q is characterized by the invariant state of the diffusion process generated on Euclidean space, then the Maxwell’s potentials appearing in Q can be seen alternatively as derived from the internal rotational degrees of freedom of the Dirac-Hestenes spinor field, yet the equivalence between Maxwell’s equation and Dirac-Hestenes equations is valid if we have that these potentials have only two components corresponding to the spin-plane. We present Lorentz-invariant diffusion representations for the Cartan–Weyl connections that sustain the equivalence of these equations, and furthermore, the diffusion of differential forms along these Brownian motions. We prove that the construction of the relativistic Brownian motion theory for the flat Minkowski metric, follows from the choices of the degenerate Clifford structure and the Oron and Horwitz relativistic Gaussian, instead of the Euclidean structure and the orthogonal invariant Gaussian. We further indicate the random Poincaré–Cartan invariants of phase-space provided with the canonical symplectic structure. We introduce the energy-form of the exact terms of Q and derive the relativistic quantum potential from the groundstate representation. We derive the field equations corresponding to these exact terms from an average on the invariant state Cartan scalar curvature, and find that the quantum potential can be identified with 1 / 12R(g), where R(g) is the metric scalar curvature. We establish a link between an anisotropic noise tensor and the genesis of a gravitational field in terms of the generalized Brownian motions. Thus, when we have a nontrivial curvature, we can identify the quantum nonlocal correlations with the gravitational field. We discuss the relations of this work with the heat kernel approach in quantum gravity. We finally present for the case of Q restricted to this exact term a supersymmetric system, in the classical sense due to E.Witten, and discuss the possible extensions to include the electromagnetic potential terms of Q.

The article argues that environmental planetary discourses have coalesced into the Anthropocene crisis narrative and reformulated the state of nature apparatus of Western political theory. The Anthropocene, as an ecological state of nature of late capitalism, casts light on the logics of geopower, which assembles species thinking, a fascination with nonlife and sovereignty, and the imaginary of extinction and mutation. Geopower shifts governmental technologies from human populations and their ‘milieu’ to nonhuman species, energy flows and ecosystems, from political economy (...) and biopower to Earth science and systems ecology. This configuration of power suggests a shift in the neoliberal agenda and imposes the Earth as a political personage, generating threatening political myths and figures of chaos and sovereignty, such as Gaia, Chthulu and Climate Leviathans.

The pagination of Simon and Schuster’s edition (New York, ) is (...) different and spans pages – instead of the first British edition’s –. The very first edition of the book (New York: Columbia U. P., ) contained two paragraphs comparing Catholicism and Communism that were overlooked for the British and all subsequent editions. Russell regarded them as important, and Sir Stanley Unwin wrote him that they would be incorporated in the next printing. The next printing was not until , and the paragraphs were again overlooked. They belong just before the paragraph on page  beginning “Every fanatical creed” in Chapter , “Science and Values”. These paragraphs are not indexed.—Ed. I meet many people who think that the evils of Communism can be combated by Catholicism. This seems to me a dangerous error. What are the evils of Communism as it has developed? First, adherence to a rigid and static system of doctrine, of which part is doubtful and part demonstrably false. Second, persecution as a means of enforcing orthodoxy. Third, a belief that salvation is only to be found within the Church and that the True Faith must be spread throughout the world, by force if necessary. (These are the beliefs of Communists.) Fourth, that the priesthood, which alone has the right to interpret the Scriptures, has enormous power, physical east of the Iron Curtain and spiritual over the faithful in partibus. Fifth, that this power is used to secure an undue share of wealth for the priesthood at the expense of the rest of the population. Sixth, that bigotry, and the hostility that it engenders, is a potent source of war. Every one of these evils was exhibited by the Catholic Church when it had power and would probably be exhibited again if it recovered the position it had in the Middle Ages. It is therefore irrational to suppose that much would be gained if, in the defeat of Communism, Catholicism were enthroned in its place.

Since 2002, at least two kinds of laboratory-testable, solid-state Maxwell demons have been proposed that utilize the electric field energy of an open-gap n-p junction and that seem to challenge the validity of the Second Law of Thermodynamics. In the present paper we present some arguments against the alleged functioning of such devices.

There exist different kinds of averaging of the differences of the energy–momentum and angular momentum in normal coordinates NC(P) which give tensorial quantities. The obtained averaged quantities are equivalent mathematically because they differ only by constant scalar dimensional factors. One of these averaging was used in our papers [J. Garecki, Rep. Math. Phys. 33, 57 (1993); Int. J. Theor. Phys. 35, 2195 (1996); Rep. Math. Phys. 40, 485 (1997); J. Math. Phys. 40, 4035 (1999); Rep. Math. Phys. 43, 397 (...) (1999); Rep. Math. Phys. 44, 95 (1999); Ann. Phys. (Leipzig) 11, 441 (2002); M.P. Dabrowski and J. Garecki, Class. Quantum. Grar. 19, 1 (2002)] giving the canonical superenergy and angular supermomentum tensors. In this paper we present another averaging of the differences of the energy–momentum and angular momentum which gives tensorial quantities with proper dimensions of the energy–momentum and angular momentum densities. We have called these tensorial quantities “the averaged relative energy–momentum and angular momentum tensors”. These tensors are very closely related to the canonical superenergy and angular supermomentum tensors and they depend on some fundamental length L > 0. The averaged relative energy–momentum and angular momentum tensors of the gravitational field obtained in the paper can be applied, like the canonical superenergy and angular supermomentum tensors, to coordinate independent analysis (local and in special cases also global) of this field. Up to now we have applied the averaged relative energy–momentum tensors to analyze vacuum gravitational energy and momentum and to analyze energy and momentum of the Friedman (and also more general, only homogeneous) universes. The obtained results are interesting, e.g., the averaged relative energy density is positive definite for the all Friedman and other universes which have been considered in this paper. (shrink)

Instead of relying on the usual price elasticity technique, this book combines economic and engineering analysis to study economic growth and energy demands to the year 2000. It asserts that future energy demand will be determined by two basic factors--the gross national product and the efficiency with which energy is used to produce this output in the household, commercial, industrial, and transport sectors of the economy.Labor hours multiplied by a productivity factor results in the GNP. This study (...) predicts that, in the long run, productivity in the United States will recover most of the sharp losses registered in the past five years. The study points out the decelerating population growth, the higher number of women in the labor force, and new investments as having an influence on this situation.After projecting the size and composition of each of the four energy consuming sectors that account for the total GNP. Energy and Economic Growth estimates efficiency improvements for each. It shows, for example, that higher levels of thermal insulation will reduce sharply energy needs for household heating and cooling. Similarly, the study notes that improvements in energy consumption per dollar of output can be made for each of the energy intensive manufacturing industries, nothing that although the savings in energy are significant, none is a consequence of pushing improvements to known technological limits. Finally, the book establishes the price elasticities that are inherent in the calculated energy requirements and checks these against elasticity estimates made by other researchers. (shrink)

Phytomass cultivation for energy use is increasingly popular in Europe for high profits guaranteed by subsidy. Although public interest in ecology is on an increasing level, direct combustion is still preferred even though scholars have been warning about formations of hazardous compounds for a long-time. However, the reduction of subsidies would negatively affect an already bad situation in Czech agriculture, since most farmers became fully dependent on subsidies due to quotas, restrictions, and other unequal business conditions in European Union. (...) It was proved in a commercial scale that an alternative phytomass energy utilizing technology consisting of steam explosion and subsequent anaerobic fermentation may be run solely on the waste heat without any further addition of chemicals. Behavior analysis of present and future agriculture decision-makers showed that none of the farmers who visited the facility cared about ecological consequences. On the other hand, ost students from the Faculty of Agriculture and the Faculty of the Economy answered the questionnaire with higher environmental responsibility. We assume this is caused by high average age of farmers in Czech Republic who are more aware of the ongoing economical difficulties and perceive differently the risk of higher acquisition costs.

This paper studies the state of charge estimation of supercapacitors and lithium batteries in the hybrid energy storage system of electric vehicles. According to the energy storage principle of the electric vehicle composite energy storage system, the circuit models of supercapacitors and lithium batteries were established, respectively, and the model parameters were identified online using the recursive least square method and Kalman filtering algorithm. Then, the online estimation of SOC was completed based on the Kalman filtering algorithm (...) and unscented Kalman filtering algorithm. Finally, the experimental platform for SOC estimation was built and Matlab was used for calculation and analysis. The experimental results showed that the SOC estimation results reached a high accuracy, and the variation range of estimation error was [−0.94%, 0.34%]. For lithium batteries, the recursive least square method is combined with the 2RC model to obtain the optimal result, and the estimation error is within the range of [−1.16%, 0.85%] in the case of comprehensive weighing accuracy and calculation amount. Moreover, the system has excellent robustness and high reliability. (shrink)

This paper considers questions about continuity and discontinuity between life and mind. It begins by examining such questions from the perspective of the free energy principle (FEP). The FEP is becoming increasingly influential in neuroscience and cognitive science. It says that organisms act to maintain themselves in their expected biological and cognitive states, and that they can do so only by minimizing their free energy given that the long-term average of free energy is entropy. The paper (...) then argues that there is no singular interpretation of the FEP for thinking about the relation between life and mind. Some FEP formulations express what we call an independence view of life and mind. One independence view is a cognitivist view of the FEP. It turns on information processing with semantic content, thus restricting the range of systems capable of exhibiting mentality. Other independence views exemplify what we call an overly generous non-cognitivist view of the FEP, and these appear to go in the opposite direction. That is, they imply that mentality is nearly everywhere. The paper proceeds to argue that non-cognitivist FEP, and its implications for thinking about the relation between life and mind, can be usefully constrained by key ideas in recent enactive approaches to cognitive science. We conclude that the most compelling account of the relationship between life and mind treats them as strongly continuous, and that this continuity is based on particular concepts of life (autopoiesis and adaptivity) and mind (basic and non-semantic).

Over and above the probable peaking of worldwide oil production as a current reality, the arrival of hard limits on all energy resources is very much nearer in the future than many people realize. The public discourse on Peak Oil and the associated arrival of hard limitson energy availability has attracted more than its share of brilliant and creative minds. In addition to scientific and technical analysts, thisgroup includes a fair number of generalists who have engaged in broader (...) forms of reflection upon the likely economic, social, political, and cultural effects of Peak Oil and other hard energy limits on the structure of current world civilization. In this paper, I select for examination three such generalists who are both especially talented and widely read by those having an interest in this topic: James Howard Kunstler, John Michael Greer, and Dmitri Orlov. My intention is to survey their central ideas in turn, with a view to forming a reasonably well-developed and concrete notion as to how the impending arrival of hard limits on energy consumption will affect the structure of built space in coming decades. I focus both on the macro-infrastructural level and on what one might term the micro-infrastructural level of the built space within which the denizens of contemporary industrial civilization live their daily lives. Theprincipal focus of the discussion will be on the situation in the United States, though many of the lines of argument presented may be applied much more broadly if suitably adjusted in light of locally prevailing conditions elsewhere.

Considering only exchange forces, the binding energies and excited states of nuclei up to 24 Mg are predicted to within charge independence, and there is no reason why the model should not be extended to cover all of the elements. A comparison of theory with experiment shows that the energy of one exchange is 2.56 MeV. Moreover, there is an attractive well of depth 30 MeV, corresponding to the helium nucleus, before exchange forces become operative. A possible explanation (...) of the origin of mesons is also presented. (shrink)

This case study of a 2016 Florida constitutional amendment analyses the semiotic devices and mechanisms of shaping public opinion on solar energy and beliefs about energy distribution. After a nationwide rise in rooftop solar installations between 2014 and 2015, utilities in several US states were faced with challenges to their business models. Anticipating similar problems in Florida, utilities and energy corporations promoted constitutional amendments. This semiotic analysis follows the voter from the billboards and flyers to the (...) text on the ballot. Starting from Peirce’s phenomenological categories, this critical analysis of the campaign reveals how the goals of the amendment were shrouded in positive environmental and consumer protection narratives. Lakoff ’s cognitive linguistics and Stibbe’s ecolinguistics support a deeper analysis of the ballot text. This study shows that by leaving key concepts (especially net metering) out of the discourse, the ballot text successfully framed an anti-solar amendment as a pro-consumer measure, while hiding the direct legal implications concerning alternative energy distribution. In particular, this study explains the opposition to the sharing of surplus in the context of neoclassical economics as a key factor in shaping beliefs about alternative energy distribution.

Precise prediction of future vehicle information can improve the control efficiency of hybrid electric vehicles. Nowadays, most prediction models use previous information of vehicles to predict future driving velocity, which cannot reflect the impact of the driver and the environment. In this paper, a real-time energy management strategy based on driver-action-impact MPC is proposed for series hybrid electric vehicles. The proposed EMS consists of two modules: the velocity prediction module and the real-time MPC module. In the velocity prediction module, (...) a long short-term memory neural network model, which is trained by the traffic data derived from a VR-based driving simulator, is adopted to predict the future driving information by using driver action information and current vehicle’s velocity. The obtained future driving velocity is treated as the inputs of the real-time MPC module, which outputs the control variables to act on the underlying controllers of power components by solving a standard quadratic programming problem. Compared with the rule-based strategy, a 5.6% average reduction of fuel consumption is obtained. The effectiveness of real-time computation of the EMS is validated and verified through a hardware-in-the-loop test platform. (shrink)

Is it about energy?! This paper consists of the analysis of the construction of the Fierza's dam, built on the Drin river bed in 1978. During the study of the dam construction scheme and later during the design of the projects, various problems were taken into account, such as the geological conditions of the area where the hydropower plants were erected, the construction materials, the most suitable solution for the type of dam, the auxiliary works, their construction, sequence and (...) time. For centuries, the world's water resources have been developed to benefit mankind. The construction of dams in order to create reservoirs has served many purposes. These are some common uses such as water supply, hydroelectric power, flood control, irrigation, and navigation. The dams are also used to regulate the flow of water in rivers. Water can be released from the reservoir during drier seasons to support wildlife and the environment downstream, and to provide a resource for human uses. Dams have long been viewed as a symbol of human ingenuity and among them is the Fierza's dam, one of the greatest achievements in Albania. During the period of the construction of the dam, Albania was in difficulty to finance the design and the implementation of such works that envisaged large dams. Regardless of everything, the small state of Albania managed to build magnificent hydropower works with great economic value and a high technical and scientific level, such as Fierza's hydropower plant. This paper aims to show the importance of the construction of Fierza's dam in the production of energy in the country with an annual average output of 1,330 GWh. Also, the importance of Fierza, besides energy production, relates to the capacity of its lake, which regulates the annual inflows, increasing the efficient use throughout the cascade. (shrink)

This paper suggests an epistemic interpretation of Belnap’s branching space-times theory based on Everett’s relative state formulation of the measurement operation in quantum mechanics. The informational branching models of the universe are evolving structures defined from a partial ordering relation on the set of memory states of the impersonal observer. The totally ordered set of their information contents defines a linear “time” scale to which the decoherent alternative histories of the informational universe can be referred—which is quite necessary for (...) assigning them a probability distribution. The “historical” state of a physical system is represented in an appropriate extended Hilbert space and an algebra of multi-branch operators is developed. An age operator computes the informational depth of historical states and its standard deviation can be used to provide a universal information/energy uncertainty relation. An information operator computes the encoding complexity of historical states, the rate of change of its average value accounting for the process of correlation destruction inherent to the branching dynamics. In the informational branching models of the universe, the asymmetry of phenomena in nature appears as a mere consequence of the subject’s activity of measuring, which defines the flow of time-information.

After the Fukushima Daiichi nuclear disaster, the Japanese government tried to democratize energy policy-making by introducing public participation. Over the course of its implementation, however, public participation came to be subordinated to expert committees as the primary mechanism of policy rationalization. The expert committees not only neutralized the results of public participation but also discounted the necessity of public participation itself. This trajectory of public participation, from its historic introduction to eventual collapse, can be fully explained only in reference (...) to complex interactions between the macroinstitutions and microsituations of Japanese policy-making at the time of the nuclear disaster: the macroinstitutional reassembling of the developmental state to reallocate more power from the bureaucracy to the cabinet office and the civil society vis-à-vis the microsituational, shifting power dynamics involving political parties, citizens and NGOs, businesses and labor unions, and other relevant actors. This case study thus helps advance the growing science and technology studies research on how the macro and microparameters of policy-making, ranging from the durable institutions of nation-states to situationally specific political struggles, combine to shape the designs, implementations, and policy influences of public participation at particular places and times as well as in particular policy domains.

Sentiment analysis is also known as opinion mining. It has an important role in natural language processing and data mining. It involves extracting and analyzing subjective information from textual data to determine the sentiment. With the advancement of technology, it is increasingly important to understand users' opinions and sentiments regarding a particular product, service or issue. This research aims to optimize the marketing strategy of energy products in SOE subsidiaries through sentiment analysis using the VADER and LSTM methods on (...) social media.The researcher analyzed data from twitter to identify consumer sentiment towards energy products. The results of the analysis show that the combination of VADER and LSTM is effective in identifying the nuances of sentiment, with the accuracy of sentiment classification reaching 85%. Based on the analysis, the researchers developed recommendations for marketing strategies that are more focused and responsive to public perception. This study also highlights the importance of two-way interaction between companies and consumers as part of an effective marketing strategy. The findings of this study are expected to be used as a reference by state-owned companies in the energy sector to improve the effectiveness of their marketing strategies through a sentiment analysis approach on social media.

Here, in our approximation of polaron theory, we examine the importance of introducing theT product, which turn out to be a very convenient theoretical approach for the calculation of thermodynamical averages.We focus attention on the investigation of the so-called linear polaron Hamiltonian and present in detail the calculation of the correlation function, spectral function, and Green function for such a linear system.It is shown that the linear polaron Hamiltonian provides an exactly solvable model of our system, and the result (...) obtained with this approach holds true for an arbitrary coupling constant which describes the strength of interaction between the electron and the lattice vibrations. Then, with the help of a variational technique, we show the possibility of reducing the real polaron Hamiltonian to a socalled trial or approximate linear model Hamiltonian.We also consider the exact calculation of free energy with a special technique that reduces calculations with the help of the T product, which, in our opinion, works much better and is easier than other analogous considerations, for example, the path-integral or Feynman-integral method.(1,2)Here we furthermore recall our own work,(4) where it was shown that the results of Refs. 7 and 8 concerning the impedance calculation in the polaron model may be obtained directly without the use of the path-integral method.The study of the polaron system's thermodynamics is carried out by us in the framework of the functional method. A calculation of the free energy and the momentum distribution function is proposed.Note also that the polaron systems with strong coupling(9) proved to be useful in different quantum field models in connection with the construction of dynamical models of composite particles. A rigorous solution of the special strong-coupling polaron problem, describing the interaction of a nonrelativistic particle with a quantum field, was given by Bogolubov.(3) The works of Tavkhelidze, Fedyanin, Khrustalev, and others(10–13) are dedicated to the further development and generalization of the Bogolubov method.Notice, too, that the electron-photon interaction effects play an important part in many problems of modern solid state theory (see, e.g., Refs. 7 and 14–19).The present paper summarizes a set of lectures delivered as a special course in the physics department of Moscow State University.

Water quality control helps in the estimation of water bodies and detects the span of pollutants and their effect on the neighboring environment. This is why the water quality of the northern part of Lake Manzala has been studied here from January to March, 2016. This study aims to model and create a program for linear and nonlinear regression of the water elements in Lake Manzala to assess and predict the water quality. Water samples have been extracted from various depths, (...) and physio-chemical properties and heavy metal concentrations have been evaluated. This study has proposed a new algorithm for predicting water quality called “Algorithm of Estimation Regression Model”. On the contrary, in renewable energy applications, statistical modeling and forecasting the solar radiation remains a significant issue with detect to reinforce power management. A new proposed method for forecasting the average Monthly Global Solar Energy in Queensland, Australia, is called, Converting Data Set into Markov Model. It was used to obtain Markov transition probability matrices for three and six states of the solar energy. The proposed forecasting method yielded accurate results with minimal error. (shrink)

The status of the geodesic principle in General Relativity has been a topic of some interest in the recent literature on the foundations of spacetime theories. Part of this discussion has focused on the role that a certain energy condition plays in the proof of a theorem due to Bob Geroch and Pong-Soo Jang [“Motion of a Body in General Relativity.” Journal of Mathematical Physics16(1) (1975)] that can be taken to make precise the claim that the geodesic principle is (...) a theorem, rather than a postulate, of General Relativity. In this brief note, I show, by explicit counterexample, that not only is a weaker energy condition than the one Geroch and Jang state insufficient to prove the theorem, but in fact a condition still stronger than the one that they assume is necessary.

Photo by Alex Guillaume on Unsplash Introduction The problem of climate change raises some important philosophical, existential questions. I propose a radical solution designed to provoke reflection on the role of humans in climate change. To push the theoretical limits of what measures people are willing to accept to combat it, an extreme population control tool is proposed: allowing people to reproduce only if they make a financial commitment guaranteeing a carbon-neutral upbringing. Solving the problem of climate change in the (...) long run by halting the procreation of human beings is controversial. In the absence of human beings and consequent climate change, other animals and plant species would benefit from an atmosphere more conducive to prolonging their existence and even improving their ability to thrive. If someone were to invent something to reverse the effects of climate change and improve animals’ lives, then human beings’ presence would be justified by the invention. Whether the propagation of the human species is beneficial to anyone or anything but human beings themselves is difficult to answer. Perhaps human beings are unfit to tackle this issue, being unable to judge it objectively. Managing Procreation: An alternative to Piecemeal Approaches Measures aimed at reducing greenhouse gases by nudging individuals and corporations may have a positive effect, but if their behavior is not climate neutral, they continue to contribute to climate change. Consequently, as long as the number of people increases, reducing greenhouse gases is at best a mitigation tool. If humans could rely solely on renewable energy, decreasing the population arguably would not be necessary. Significantly reducing the number of people appears to provide a solution to both problems: people who do not exist do not contribute to climate change, and renewable energy could meet the demand of a smaller population. One option is to let only those who produce the problem pay for its solution. One could determine the expected annual emission of greenhouse gases per person, assuming an average life expectancy, and calculate the costs to compensate them by, e.g., installing extra solar panels. Those expected costs could then be paid by the parents of each new person annually over the first eighteen years of that person’s life by dividing the total expected costs by eighteen. There are also practical difficulties. It would be difficult to determine the payment necessary. What should be done if a child has been born whose parents cannot afford to pay? In addition, child benefits could be canceled, contrary to recent incentives for child births instated in Italy,[1] where additional benefits will be made available to pay for childcare, and Hungary,[2] where women with four children or more will be exempted for life from paying income tax. A transition period could exist once the policy has been adopted, since it would be unreasonable to confront those who are already pregnant with costs they could not reasonably have expected. While the analysis is both hypothetical and theoretical, the impracticality is a noteworthy obstacle. There are several practical issues that cannot be addressed here, like the difficulty of calculating the added negative effects of each new individual and the unlikelihood that many citizens will support politicians who propose adopting policies that discourage having children. The upshot of what I have proposed is that climate change can be solved in the long run without financial costs to society as a whole, notwithstanding the transitional measures that would bring costs with them. Managing Procreation to Reduce Suffering Should this be deemed too harsh a stance, it is important to consider the basic issue of whether it is justified to introduce measures to reduce the number of people in an already overpopulated world, especially if climate change leads to additional suffering. One need not agree with Benatar, but his perspective must at least be taken seriously: It is curious that while good people go to great lengths to spare their children from suffering, few of them seem to notice that the one guaranteed way to prevent all the suffering of their children is not to bring those children into existence in the first place.[3] Benatar argues that non-existence is preferable to existence,[4] which raises the question why new people should be created at all. Those who question whether this planet will be habitable for future generations presuppose that such generations will exist. If people are not brought into existence, they may be said to be deprived of what life has to offer, but life must not be presupposed to be something positive. Whether this is the case in fact merits an inquiry of its own. A solution to the problem of climate change despite an increased population does not equate to a positive outcome since it merely means that something negative is removed. After all, solving the problem is not a means to an end, but a means to a means, the latter means being a means to a happy life, which does not automatically ensue from a solution to the problem. Benatar, as an anti-natalist, argues that procreation is morally wrong. His basic idea is that there is an asymmetry between pleasure and pain and that the pleasure that is not experienced by someone because that person does not exist is not something bad whereas the absence of pain that is not experienced – for the same reason – is something good.[5] Accordingly, “The reason why we do not lament our failure to bring somebody into existence is because absent pleasures are not bad.”[6] One may question whether such a perspective suffices to prove that coming into existence is always a harm, but the assertion that coming into existence exposes a new being to potential harm is clear. Objections A drawback of the proposed radical solution, placing the financial impediment on procreation, is that it will not solve climate change in the short run. A significant drop in the number of people may have a positive effect in the long run, but for now the behavior of the people in existence is the problem. Other climate change mitigation policies would necessarily continue. Additionally, there are important practical reasons to continue to procreate. The benefits for the elderly are paid for by the labor force. It is a problem that new generations are created as mere means to benefit older people. Perhaps more troubling, a pyramid scheme is created: by the time those people have themselves become old, a new labor force must have been brought into existence, a process that must presumably continue. If a consideration for people in developing countries to have children is that they cannot provide for themselves at an advanced age, while benefits are either lacking or insufficient, developed countries could collectively fund a pension scheme.[7] This may be low-cost if it is tailored to the living standard in the countries in question and given the life expectancy. Such a pension scheme should be predicated on the countries’ efforts in reducing the birth rate. If the labor force decreases, the economy may suffer. The focus on economic growth is arguably one of the causes of climate change, but if the number of people is reduced, the living standard does not have to be compromised, since the economy can then still grow. If fewer people began to use natural resources and nonrenewable energy at higher per capita rates, then the procreation might not be beneficial to the climate. It would need to be accompanied by regulations on use. One may also object that only wealthy people will be able to afford children. This is correct, but there is no right to have a child one cannot afford. The right to procreate does not entail the right to have as many children as one wants.[8] Yet in many countries, like the United States, it is a fundamental right that is constitutionally protected. There are numerous social, emotional, and even biological reasons why people choose to procreate. These may include the joy of having a family, the hope that children may bring in society, and the intergenerational transference of knowledge. People may have a strong desire to raise children or even a religious duty. If someone procures a sports car that is highly polluting, it would be justifiable to impose a tax in such a case. Many taxes and fines are imposed on corporate polluters. Procreation is significantly different but if the issue is regarded with some distance, then a climate change prevention tax could be appropriate. Some may argue that raising children is expensive already, which nonetheless does not deter people from having children. The tax I propose would be additional and specifically dedicated to carbon neutrality, but it would be difficult to predict whether it would discourage procreation. One last objection may be that for those now dedicated to sustainability for preserving the earth for the sake of future generations, there would be little or no incentive to continue any climate change mitigation efforts at all. If they sense they cannot afford to procreate, they may simply use every natural resource rather than save the earth for animals or for next generations. In a democracy, this problem does not exist if the majority can afford to procreate and agree with legislation on the basis of which such behavior is discouraged or punished. CONCLUSION Prior to their existence, there is no obligation to bequeath the earth to next generations. Such generations will only exist if they are actually created, and there is no obligation to create them. The lack of existence should not be confused with harm. Climate change provides an important reason to stem overpopulation. Ironically, fast rates of procreation may lead to the earth becoming uninhabitable for humans altogether. The radical solution that has been proposed here is an unrealistic scenario. For now, the average global birth rate is just over 18 per thousand people, but there is a need to ensure that the number of people is not greater than the planet can endure. While it is better to prevent problems than to solve them, the interest in procreation and its associated joys, usefulness, and cultural value make mass reduction in the population unlikely. Some countries have smaller average family size than others and can act as models for reducing population in a less radical way. The need to continue efforts to reduce climate change persists. Whether it would curb population growth or not, an additional financial burden applied to neutralizing each person’s offspring’s carbon footprint provides a meaningful thought exercise that could help alleviate the pressure on current climate mitigation strategies.

In this third paper in a series on stochastic electrodynamics (SED), the nonrelativistic dipole approximation harmonic oscillator-zero-point field system is subjected to an arbitrary classical electromagnetic radiation field. The ensemble-averaged phase-space distribution and the two independent ensemble-averaged Liouville or Fokker-Planck equations that it satisfies are derived in closed form without furtner approximation. One of these Liouville equations is shown to be exactly equivalent to the usual Schrödinger equation supplemented by small radiative corrections and an explicit radiation reaction (RR) vector potential (...) that is similar to the Crisp-Jaynes semiclassical theory (SCT) RR potential. The wave function in this SED Schrödinger equation is shown to have thea priori significance of position probability amplitude. The other Liouville equation has no counterpart in ordinary quantum mechanics, and is shown to restrict initial conditions such that (i) The Wigner-type phase-space distribution is always positive, (ii) in the absence of an applied field, the only allowed solution of both equations is the quantum ground state, and (iii) if a previously applied field is suddenly turned off, then spontaneous transitions occur, with no need for a triggering perturbation as in SCT, until the system is in the ground state. It is also shown that the oscillator energy is a fluctuating quantity that must take on a continuum of values, with average value equal to the quantum ground-state energy plus a contribution due to the applied classical field.

A (to our knowledge) novel Generalized Nonlinear Schrödinger equation based on the modifications of Nottale-Cresson’s fractal-scale calculus and resulting from the noncommutativity of the phase space coordinates is explicitly derived. The modifications to the ground state energy of a harmonic oscillator yields the observed value of the vacuum energy density. In the concluding remarks we discuss how nonlinear and nonlocal QM wave equations arise naturally from this fractal-scale calculus formalism which may have a key role in the final (...) formulation of Quantum Gravity.

This article advances recent scholarship on energy security by arguing that the concept is best understood as a sociotechnical imaginary, a collective vision for a “good society” realized through technoscientific-oriented policies. Focusing on the 1952 Resources for Freedom report, the authors trace the genealogy of energy security, elucidating how it establishes a morality of efficiency that orients policy action under the guise of security toward the liberalizing of markets in resource states and a robust program of (...) class='Hi'>energy research and development in the United States. This evidence challenges the pervasive historical anchoring of the concept in the 1970s and illustrates the importance of the genealogical approach for the emerging literature on energy and sociotechnical imaginaries. Exploring the genealogy of energy security also unpacks key social, political, and economic undercurrents that disrupt the seeming universality of the language of energy, leading the authors to question whether energy security discourse is appropriate for guiding policy action during ongoing global energy transitions.

The hydrogen economy has received increasing attention recently. Common reasons cited for investigating hydrogen energy options are improved energy security, reduced environmental impacts, and its contribution to a transition to sustainable energy sources. In anticipation of these benefits, national and local initiatives have been launched in the United States, creating pilot “roadmaps” and technology partnerships to explore hydrogen economy platforms. Although hydrogen can provide several positive improvements over a carbon- or uranium-based energy system, several problems (...) are also likely. As well, competitive technologies (e.g., hybrid vehicles) may offer comparatively greater economic and/or environmental advantages. Before policies to advance a hydrogen energy economy proceed, it is vital that all aspects of hydrogen be compared with other available alternatives. Important questions to ask in this regard are whether a hydrogen economy can fulfill key energy needs and whether there are appropriate roles for hydrogen to play in a sustainable energy future.

If one formulates Helmholtz's ideas about perception in terms of modern-day theories one arrives at a model of perceptual inference and learning that can explain a remarkable range of neurobiological facts. Using constructs from statistical physics it can be shown that the problems of inferring what cause our sensory inputs and learning causal regularities in the sensorium can be resolved using exactly the same principles. Furthermore, inference and learning can proceed in a biologically plausible fashion. The ensuing scheme rests on (...) Empirical Bayes and hierarchical models of how sensory information is generated. The use of hierarchical models enables the brain to construct prior expectations in a dynamic and context-sensitive fashion. This scheme provides a principled way to understand many aspects of the brain's organisation and responses. In this paper, we suggest that these perceptual processes are just one emergent property of systems that conform to a free-energy principle. The free-energy considered here represents a bound on the surprise inherent in any exchange with the environment, under expectations encoded by its state or configuration. A system can minimise free-energy by changing its configuration to change the way it samples the environment, or to change its expectations. These changes correspond to action and perception, respectively, and lead to an adaptive exchange with the environment that is characteristic of biological systems. This treatment implies that the system's state and structure encode an implicit and probabilistic model of the environment. We will look at models entailed by the brain and how minimisation of free-energy can explain its dynamics and structure. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 20 (2000) 23-42 [Access article in PDF] Overcoming the Grip of Consumerism Stephanie KazaUniversity of VermontFor fifteen years the Worldwatch Institute of Washington, D. C. has been publishing a review of the declining condition of the global environment (Brown et al. 1998). For the most part, the picture is not good. Much of the deterioration can be traced directly to human activities--urban expansion equates to species loss, (...) industrial manufacturing to air pollution, factory farming to water pollution, chemical agriculture to poisoned soil. Accelerating these environmental impacts are rapidly rising population numbers, increasingly efficient technologies, and consumption rates beyond the planet's capacity. These three have been linked by the equation I=PAT, or environmental impact=population size multiplied by affluence (or degree of consumption) multiplied by technology. Reduce any one of these and the impact drops; increase one or all three, and the impact rises, in some cases dramatically.Much of the conversation among scientists and technologists has focused on the P (population) and T (technology) parts of the equation, with grave concerns that rising population numbers are swamping earth systems, yet often with buoyant optimism that technological breakthroughs will solve everything. These two perspectives dominated political discussion for much of the 1960s and 1970s (Ehrlich et al. 1977 and Lovins 1977, among others). But by the 1980s the facts were incontrovertible: high rates of consumption were driving environmental destruction just as fast if not faster than rising population. At the 1992 Rio Summit in Brazil, representatives of southern countries demanded that high-consuming northern countries examine their own contribution to the environmental crisis rather than placing blame elsewhere. It is our obligation in the North to respond to these serious requests.How much do people in northern industrialized countries consume? Here are some indicator figures: Americans consume their average body weight (120 pounds) every day in materials extracted and processed from farms, mines, range lands, and forests (Ryan and Durning 1997, 5). In the United States, the number of shopping malls (close to 35,000) eclipsed the number of high schools in 1987 (Dunning 1992, 130). Since 1950 the per capita consumption of energy, meat, and lumber has doubled, use of plastic has increased five times, use of aluminum seven times, and average airplane miles per person has soared 33-fold (Durning 1992, 29). As products have proliferated, we see the swelling ecological footprint behind each new thing: clear-cut forests replacing paper plantations in Thailand, toxic oil polluting native lands of Ecuador, women earning poverty wages assembling computer chips in [End Page 23] Malaysia--the stories are not as pretty as the products. Materials extraction, production, distribution, use, and waste disposal--all of these have ecological costs, many of which are life threatening.Why should Buddhists and Christians address consumption? For starters, it is a nonsectarian issue; responsibility cuts across denominations and religious belief systems. Collaboration of all kinds is needed to take apart this juggernaut of complex causes and conditions. I believe the Buddhist tradition has powerful analytical tools and spiritual practices which may be helpful in this undertaking. These may aid or inspire similar efforts explored through the Christian heritage. A survey of the landscape and the literature shows it is shockingly clear: the challenge here is enormous. It will require all the spiritual insight, dedication, and sheer stamina we can bring to it. This work cannot be done alone; we need each other's help to keep going through the many obstacles.To date, Buddhist initiatives in this conversation have been modest. Several popular books have brought Buddhist perspectives to bear on consumption issues, most notably E. F. Schumacher's Small is Beautiful (1975) and Gary Snyder's The Practice of the Wild (1990). Both works popularize practices of simplicity and restraint, flavored by the exotic Western fascination with Eastern thought. Several Buddhist teachers in the U.S. have taken up particular sub-themes addressing over-consumption. Philip Kapleau has sounded an ethical call for vegetarianism based on the first precept, "no killing" (1982). Robert Aitken has taken a stand for reducing wants and needs to simplify... (shrink)

Spontaneous brain activity has received increasing attention as demonstrated by the exponential rise in the number of published papers on this topic over the last thirty years. Such “intrinsic” brain activity, generated in the absence of an explicit task, is frequently associated with resting-state or default-mode networks. The focus on characterizing spontaneous brain activity promises to shed new light on questions concerning the structural and functional architecture of the brain and how they are related to “mind”. However, many critical questions (...) have yet to be addressed. In this review, we focus on a scarcely explored area, specifically the energetic requirements and constraints of spontaneous activity, taking into account both thermodynamical and informational perspectives. We argue that the “classical” definitions of spontaneous activity do not take into account an important feature, that is, the critical thermodynamic energetic differences between spontaneous and evoked brain activity. Spontaneous brain activity is associated with slower oscillations compared with evoked, task-related activity, hence it exhibits lower levels of enthalpy and “free-energy” (i.e. the energy that can be converted to do work), thus supporting noteworthy thermodynamic energetic differences between spontaneous and evoked brain activity. Increased spike frequency during evoked activity has a significant metabolic cost, consequently, brain functions traditionally associated with spontaneous activity, such as mind wandering, require less energy that other nervous activities. We also review recent empirical observations in neuroscience, in order to capture how spontaneous brain dynamics and mental function can be embedded in a non-linear dynamical framework, which considers nervous activity in terms of phase spaces, particle trajectories, random walks, attractors and/or paths at the edge of the chaos. This takes us from the thermodynamic free-energy, to the realm of “variational free-energy”, a theoretical construct pertaining to probability and information theory which allows explanation of unexplored features of spontaneous brain activity.

If one demystifies entropy the second law of thermodynamics comes out as an emergent property entirely based on the simple dynamic mechanical laws that govern the motion and energies of system parts on a micro-scale. The emergence of the second law is illustrated in this paper through the development of a new, very simple and highly efficient technique to compare time-averaged energies in isolated conservative linear large scale dynamical systems. Entropy is replaced by a notion that is much more transparent (...) and more or less dual called ectropy. Ectropy has been introduced before but we further modify the notion of ectropy such that the unit in which it is expressed becomes the unit of energy. The second law of thermodynamics in terms of ectropy states that ectropy decreases with time on a large enough time-scale and has an absolute minimum equal to zero. Zero ectropy corresponds to energy equipartition. Basically we show that by enlarging the dimension of an isolated conservative linear dynamical system and the dimension of the system parts over which we consider time-averaged energy partition, the tendency towards equipartition increases while equipartition is achieved in the limit. This illustrates that the second law is an emergent property of these systems. Finally from our large scale linear dynamic model we clarify Loschmidt’s paradox concerning the irreversible behavior of ectropy obtained from the reversible dynamic laws that govern motion and energy at the micro-scale.

MV-algebras stand for the many-valued Łukasiewicz logic the same as Boolean algebras for the classical logic. States on MV-algebras were first mentioned [20] in probability theory and later also introduced in effort to capture a notion of `an average truth-value of proposition' [15] in Łukasiewicz many-valued logic. In the presented paper, an integral representation theorem for finitely-additive states on semisimple MV-algebra will be proven. Further, we shall prove extension theorems concerning states defined on sub-MV-algebras and normal partitions (...) of unity generalizing in this way the well-known Horn-Tarski theorem for Boolean algebras.

In this paper, we aim at rethinking the concept of obesity in a way that better captures the connection between underlying medical aspects, on the one hand, and an individual’s developmental history, on the other. Our proposal rests on the idea that obesity is not to be understood as a phenotypic trait or character; rather, obesity represents one of the many possible states of a more complex phenotypic trait that we call ‘energy metabolism.’ We argue that this apparently (...) simple conceptual shift can help solve important theoretical misconceptions regarding the genetics, epigenetics, and development of obesity. In addition, we show that our proposal can be fruitfully paired with the concept of developmental channeling of a trait, which connects to the study of the plasticity and canalization of complex traits. Finally, we discuss the potential impact of our approach on the assessment, treatment, and social narratives of obesity. (shrink)

Trapezoidal cubic fuzzy numbers (TzCFNs) are an extraordinary cubic fuzzy set on a real number set. TzCFNs are useful for dealing with well-known quantities in decision data and decision making problems themselves. This paper is about multi-attribute group decision making problems in which the attribute values are stated with TzCFNs, which are solved by developing a new decision method based on power average operators of TzCFNs. The new operation laws for TzCFNs are given. Hereby, the power average operator of real (...) numbers is extended to four kinds of power average operators of TzCFNs, involving the power average operator of TzCFNs, the weighted power average operator of TzCFNs, the power ordered weighted average operator of TzCFNs, and the power hybrid average operator of TzCFNs. In the proposed group decision method, the individual overall evaluation values of alternatives are generated by using the power average operator of TzCFNs. Applying the hybrid average operator of TzCFNs, the specific general evaluation standards of alternatives are then combined into the collective ones, which are used to rank the alternatives. The example analysis shows the practicality and effectiveness of the proposed method. (shrink)

The mathematical dynamic model of oxidative phosphorylation in muscle mitochondria developed previously was used to calculate the flux control coefficients of particular steps of this process in isolated mitochondria at different amounts of hexokinase and oxygen concentrations. The pattern of control was completely different under different conditions. For normoxic concentration, the main controlling steps in state 4, state 3.5 and state 3 were proton leak, ATP usage (hexokinase) and complex III, respectively. The pattern of control in state 4 was not (...) changed at hypoxic oxygen concentration, while in state 3.5 and state 3 much of the control was shifted from other steps to cytochrome oxidase. The implications of the theoretical results obtained for the regulation of oxidative phosphorylation in intact muscle are discussed. (shrink)

Lithium-ion batteries have been widely used as energy storage systems and in electric vehicles due to their desirable balance of both energy and power densities as well as continual falling price. Accurate estimation of the state-of-charge of a battery pack is important in managing the health and safety of battery packs. This paper proposes a compact radial basis function neural model to estimate the state-of-charge of lithium battery packs. Firstly, a suitable input set strongly correlated with the package (...) SOC is identified from directly measured voltage, current, and temperature signals by a fast recursive algorithm. Secondly, a RBF neural model for battery pack SOC estimation is constructed using the FRA strategy to prune redundant hidden layer neurons. Then, the particle swarm optimization algorithm is used to optimize the kernel parameters. Finally, a conventional RBF neural network model, an improved RBF neural model using the two stage method, and a least squares support vector machine model are also used to estimate the battery SOC as a comparative study. Simulation results show that generalization error of SOC estimation using the novel RBF neural network model is less than half of that using other methods. Furthermore, the model training time is much less than the LSSVM method and the improved RBF neural model using the two-stage method. (shrink)

According to the free energy principle all living systems aim to minimise free energy in their sensory exchanges with the environment. Processes of free energy minimisation are thus ubiquitous in the biological world. Indeed it has been argued that even plants engage in free energy minimisation. Not all living things however feel alive. How then did the feeling of being alive get started? In line with the arguments of the phenomenologists, I will claim that every feeling (...) must be felt by someone. It must have mineness built into it if it is to feel a particular way. The question I take up in this paper asks how mineness might have arisen out of processes of free energy minimisation, given that many systems that keep themselves alive lack mineness. The hypothesis I develop in this paper is that the life of an organism can be seen as an inferential process. Every living system embodies a probability distribution conditioned on a model of the sensory, physiological, and morphological states that are highly probably given the life it leads and the niche it inhabits. I argue for an ecological and enactive interpretation of free energy. I show how once the life of an organism reaches a certain level of complexity mineness emerges as an intrinsic part of the process of life itself. (shrink)

National scientists have elaborated the reform's gist, approaches, stages and consequences in the Ukrainian agricultural sector during the XX - XXI centuries. These studies have been conducted by N. Zhulkanych, S. Zhyvora, M. Zyza, M. Lendiel, E. Mazur, O. Malyarchuk, V. Nechytailo and many others. The paper aims to perform the comprehensive study of general trends and peculiar features of the agricultural development of the Ukrainian SSR in 1963-1990 and to define actual advances and drawbacks on the basis of analysis (...) of historical records and scientific literature. The object of research is agriculture as part of socialist economy in the USSR. The subject of research is the implementation features of agricultural policy of the Soviet power in the Ukrainian SSR, using the Western region of the Republic as an example. The economic strategy of the Soviet power involved a long-term industrialization of the agricultural sector. A distinguishing feature of the industrialization process was the use of systems of machinery in all branches of agriculture. The technological chain had to embrace the process from the sporadic application of machinery to the overall mechanization and automation of crop and livestock farming. The industrial background of production predetermined the implementation of the system of machinery with extensive power consumption, i.e. with the new technical bases. The resolutions of the March Plenum of the CPSU Central Committee defined the economic priorities and capacity development of the Republic. Capital investments were the economic basis for the increase of production potential of collective and state farms, solution of social problems in rural regions. The land productivity was increased mainly by means of land reclamation and production chemization, use of organic and mineral fertilizers, pesticides, fungicides, etc. The supply of mineral fertilizers increased, but most of them were of low quality, non-concentrated and unbalanced in nutritional ingredients. In its turn it caused irreparable damage to the environment and polluted agricultural products with chemicals. The chemization undermined the population health and disrupted the ecological balance. Despite ultimate achievements in the rise of the industrial level of agriculture of the Ukrainian SSR, it didn't meet the needs of collective and state farms. A great number of labour-intensive processes in animal and crop farming were performed manually. In state farms, contrary to collective farms, the stock of tractors was newer, but much smaller. For many years the USSR was in the top ten countries of the world in terms of consumption of energy and proteins, contained in food products per capita. However, the food patterns were inconsistent with the scientifically grounded norm. Structural imbalance of the food ration was the manifestation of the food crisis in the USSR. To meet primary needs of Soviet citizens in food products the May Plenum of the CPSU Central Committee adopted the "Food Program of the USSR for the Period until 1990 and Measures of Its Implementation". The main issue of the Food program was to increase grain harvest. Grain production was the basis for food and fodder supply of the country. Alongside with a substantial increase in food products output in public economy the attention was given to the development of subsidiary individual holdings and fruit-and-vegetable cooperatives. The cooperatives and subsidiary holdings produced a great number of dairy and meat products, vegetables and fruits both for their own needs and for sale in collective farm markets. The state food program predetermined the solution of agricultural problems by means of formerly used methods. The major problem of agriculture had to be solved by means of increase in the gross grain harvest. Thus, the implementation of agricultural policy of Soviet power in the Ukrainian SSR lead to great changes in agricultural production. At that time there appeared such new branches of economy specialized in services to agricultural production as waterworks and land reclamation, feed mill industry, farm building, machine engineering for animal farming and fodder production, procurement of agricultural products and agricultural processing. The study of this policy implementation proves that the average annual rates of agricultural production increased but they were inconsistent with high investments. On the one hand, the Food program testified the "food crisis in the USSR", demonstrating the lag of the world socialist community from capitalist states. On the other hand, it had to increase the level of food self-sufficiency, decrease the procurement of agricultural products from abroad and promote the solution of the world food problem in general.

These two perspectives dominated political discussion for much of the 1960s and 1970s (Ehrlich et al. 1977 and Lovins 1977, among others). But by the 1980s the facts were incontrovertible: high rates of consumption were driving environmental destruction just as fast if not faster than rising population. At the 1992 Rio Summit in Brazil, representatives of southern countries demanded that high-consuming northern countries examine their own contribution to the environmental crisis rather than placing blame elsewhere. It is our obligation in the North to respond to these serious requests.How much do people in northern industrialized countries consume? Here are some indicator figures: Americans consume their average body weight (120 pounds) every day in materials extracted and processed from farms, mines, range lands, and forests (Ryan and Durning 1997, 5). In the United States, the number of shopping malls (close to 35,000) eclipsed the number of high schools in 1987 (Dunning 1992, 130). Since 1950 the per capita consumption of energy, meat, and lumber has doubled, use of plastic has increased five times, use of aluminum seven times, and average airplane miles per person has soared 33-fold (Durning 1992, 29). As products have proliferated, we see the swelling ecological footprint behind each new thing: clear-cut forests replacing paper plantations in Thailand, toxic oil polluting native lands of Ecuador, women earning poverty wages assembling computer chips in [End Page 23] Malaysia--the stories are not as pretty as the products. Materials extraction, production, distribution, use, and waste disposal--all of these have ecological costs, many of which are life threatening.Why should Buddhists and Christians address consumption? For starters, it is a nonsectarian issue; responsibility cuts across denominations and religious belief systems. Collaboration of all kinds is needed to take apart this juggernaut of complex causes and conditions. I believe the Buddhist tradition has powerful analytical tools and spiritual practices which may be helpful in this undertaking. These may aid or inspire similar efforts explored through the Christian heritage. A survey of the landscape and the literature shows it is shockingly clear: the challenge here is enormous. It will require all the spiritual insight, dedication, and sheer stamina we can bring to it. This work cannot be done alone; we need each other's help to keep going through the many obstacles.To date, Buddhist initiatives in this conversation have been modest. Several popular books have brought Buddhist perspectives to bear on consumption issues, most notably E. F. Schumacher's Small is Beautiful (1975) and Gary Snyder's The Practice of the Wild (1990). Both works popularize practices of simplicity and restraint, flavored by the exotic Western fascination with Eastern thought. Several Buddhist teachers in the U.S. have taken up particular sub-themes addressing over-consumption. Philip Kapleau has sounded an ethical call for vegetarianism based on the first precept, "no killing" (1982). Robert Aitken has taken a stand for reducing wants and needs to simplify... (shrink)

The aim of this paper is twofold: (1) to assess whether the construct of neural representations plays an explanatory role under the variational free-energy principle and its corollary process theory, active inference; and (2) if so, to assess which philosophical stance - in relation to the ontological and epistemological status of representations - is most appropriate. We focus on non-realist (deflationary and fictionalist-instrumentalist) approaches. We consider a deflationary account of mental representation, according to which the explanatorily relevant contents of (...) neural representations are mathematical, rather than cognitive, and a fictionalist or instrumentalist account, according to which representations are scientifically useful fictions that serve explanatory (and other) aims. After reviewing the free-energy principle and active inference, we argue that the model of adaptive phenotypes under the free-energy principle can be used to furnish a formal semantics, enabling us to assign semantic content to specific phenotypic states (the internal states of a Markovian system that exists far from equilibrium). We propose a modified fictionalist account: an organism-centered fictionalism or instrumentalism. We argue that, under the free-energy principle, pursuing even a deflationary account of the content of neural representations licenses the appeal to the kind of semantic content involved in the aboutness or intentionality of cognitive systems; our position is thus coherent with, but rests on distinct assumptions from, the realist position. We argue that the free-energy principle thereby explains the aboutness or intentionality in living systems and hence their capacity to parse their sensory stream using an ontology or set of semantic factors.

Concerns about energy security have dramatically increased since the terrorist attacks on September 11, 2001. If U.S. energy use follows business-as-usual projections, the energy system will become increasingly vulnerable. No quick fixes are available to make the United States energy independent. However, there are energy policies that promote efficiency and the use of renewable energy sources such as wind, biomass, geothermal, and solar can gradually reduce dependence on imported oil and natural gas and (...) reduce the vulnerability of the U.S. energy infrastructure to disruption of supplies or to attack. This article reviews recent analyses by the U.S. Energy Information Administration’s and by the Union of Concerned Scientists. These studies showthat efficiency and renewable energy investments can increase energy security while lowering consumer energy bills and reducing local and global environmental hazards. (shrink)
