Large changes in a scene often become difficult to notice if made during an eye movement, image flicker, movie cut, or other such disturbance. It is argued here that this _change blindness_ can serve as a useful tool to explore various aspects of vision. This argument centers around the proposal that focused attention is needed for the explicit perception of change. Given this, the study of change perception can provide a useful way to determine the nature of visual attention, and (...) to cast new light on the way that it is?and is not?involved in visual perception. To illustrate the power of this approach, this paper surveys its use in exploring three different aspects of vision. The first concerns the general nature of _seeing_. To explain why change blindness can be easily induced in experiments but apparently not in everyday life, it is proposed that perception involves a _virtual representation_, where object representations do not accumulate, but are formed as needed. An architecture containing both attentional and nonattentional streams is proposed as a way to implement this scheme. The second aspect concerns the ability of observers to detect change even when they have no visual experience of it. This _sensing_ is found to take on at least two forms: detection without visual experience (but still with conscious awareness), and detection without any awareness at all. It is proposed that these are both due to the operation of a nonattentional visual stream. The final aspect considered is the nature of visual attention itself?the mechanisms involved when _scrutinizing_ items. Experiments using controlled stimuli show the existence of various limits on visual search for change. It is shown that these limits provide a powerful means to map out the attentional mechanisms involved. (shrink)

It has often been assumed that when we use vision to become aware of an object or event in our surroundings, this must be accompanied by a corresponding visual experience (i.e., seeing). The studies reported here show that this assumption is incorrect. When observers view a sequence of displays alternating between an image of a scene and the same image changed in some way, they often feel (or sense) the change even though they have no visual experience of it. The (...) subjective difference between sensing and seeing is mirrored in several behavioral differences, suggesting that these are two distinct modes of conscious visual perception. (shrink)

This article proposes a sensory studies methodology for the interpretation of museum objects. The proposed method unfolds in two phases: virtual encounter via an on-line catalog and actual exposure in the context of a handling workshop. In addition to exploring the écart between image and object, the “Sensing Art and Artifacts” exercise articulates a framework for arriving at a multisensory, cross-cultural, interactive understanding of aesthetic value. The case studies presented here involve four objects from the collection of the Hunterian (...) Museum as sensed and interpreted by scholars of psychology, philosophy, sociology, and anthropology. It is proposed that aesthetic judgment in the expanded (cross-cultural) sense contemplated here involves apprehending the museum object through multiple sensory modalities in place of the conventional Western fixation on visible form.

This editorial examines how sensing practices are transforming through proliferating sensor technologies and altered sensing relations. Rather than engage with sensing as a project of the human mind or body as usually delineated within sensory classifications, this overview of sensors and sensing practices documents how sensing entities are emerging that are composed of shifting ensembles of multiple humans and more-than-humans, environments and technologies, politics and practices. By decoupling sensing from its exclusive human orientation, the (...) editorial and collection demonstrate how reworked approaches to sensing make it possible to tune in to how involvement with environmental problems unfolds and endures. The collection asks how sensing practices might be crafted that attend to the distributed and accumulative inequalities of environmental problems and to speculate toward differential collectives for addressing environmental crisis and change.

Disability theory privileges masculinist notions of presence, visibility, material “reality,” and identity as “given.” One effect of this has been the erasure of “sensibility,” which, it is argued, inscribes, materializes, and performs the critique of binary thought. Therefore, sensibility must be re-articulated in order to escape the “necessary error” of identity implicit in accounts of cultural diversity, and to dialogue across difference in ways that dislocate disability from its position of disvalue in feminist thought.

It remains a standing problem how and why the first nervous systems evolved. Molecular and genomic information is now rapidly accumulating but the macroscopic organization and functioning of early nervous systems remains unclear. To explore potential evolutionary options, a coordination centered view is discussed that diverges from a standard input–output view on early nervous systems. The scenario involved, the skin brain thesis, stresses the need to coordinate muscle-based motility at a very early stage. This paper addresses how this scenario with (...) its focus on coordination also deals with sensory aspects. It will be argued that the neural structure required to coordinate extensive sheets of contractile tissue for motility provides the starting point for a new multicellular organized form of sensing. Moving a body by muscle contraction provides the basis for a multicellular organization that is sensitive to external surface structure at the scale of the animal body. Instead of thinking about early nervous systems as being connected to the environment merely through input and output, the implication developed here is that early nervous systems provide the foundation for a highly specific animal sensorimotor organization in which neural activity directly reflects bodily and environmental spatiotemporal structure. While the SBT diverges from the input–output view, it is closely linked to and supported by ongoing work on embodied approaches to intelligence to which it adds a new interpretation of animal embodiment and sensorimotor organization.

This article considers categorical perception (CP) as a crucial process involved in all sort of communication throughout the biological hierarchy, i.e. in all of biosemiosis. Until now, there has been consideration of CP exclusively within the functional cycle of perception–cognition–action and it has not been considered the possibility to extend this kind of phenomena to the mere physiological level. To generalise the notion of CP in this sense, I have proposed to distinguish between categorical perception (CP) and categorical sensing (...) (CS) in order to extend the CP framework to all communication processes in living systems, including intracellular, intercellular, metabolic, physiological, cognitive and ecological levels. The main idea is to provide an account that considers the heterarchical embeddedness of many instances of CP and CS. This will take me to relate the hierarchical nature of categorical sensing and perception with the equally hierarchical issues of the “binding problem”, “triadic causality”, the “emergent interpretant” and the increasing semiotic freedom observed in biological and cognitive systems.

In this modern world, a massive amount of data is processed and broadcasted daily. This includes the use of high energy, massive use of memory space, and increased power use. In a few applications, for example, image processing, signal processing, and possession of data signals, etc., the signals included can be viewed as light in a few spaces. The compressive sensing theory could be an appropriate contender to manage these limitations. “Compressive Sensing theory” preserves extremely helpful while signals (...) are sparse or compressible. It very well may be utilized to recoup light or compressive signals with less estimation than customary strategies. Two issues must be addressed by CS: plan of the estimation framework and advancement of a proficient sparse recovery calculation. The essential intention of this work expects to audit a few ideas and utilizations of compressive sensing and to give an overview of the most significant sparse recovery calculations from every class. The exhibition of acquisition and reconstruction strategies is examined regarding the Compression Ratio, Reconstruction Accuracy, Mean Square Error, and so on. (shrink)

Luminescence‐based sensing schemes for oxygen have experienced a fast growth and are in the process of replacing the Clark electrode in many fields. Unlike electrodes, sensing is not limited to point measurements via fiber optic microsensors, but includes additional features such as planar sensing, imaging, and intracellular assays using nanosized sensor particles. In this essay, I review and discuss the essentials of (i) common solid‐state sensor approaches based on the use of luminescent indicator dyes and host polymers; (...) (ii) fiber optic and planar sensing schemes; (iii) nanoparticle‐based intracellular sensing; and (iv) common spectroscopies. Optical sensors are also capable of multiple simultaneous sensing (such as O2 and temperature). Sensors for O2 are produced nowadays in large quantities in industry. Fields of application include sensing of O2 in plant and animal physiology, in clinical chemistry, in marine sciences, in the chemical industry and in process biotechnology. (shrink)

Instead of presuming the ‘observer’ as given, we are (re)sensing the observer and are thereby offering an ‘open order cybernetics’ (OOC). We are first of all concerned about our acquisition and use of language as the precondition for any meaningful statement. This self-reflexive point of departure distinguishes our project from philosophers who are presuming ‘something’ (‘closure’, ‘selforganization’, ‘self ’, ‘auto-poiesis’, ‘senses’, ‘objects’, ‘subjects’, ‘language’, ‘nervous systems’ etc.) in the first place without being aware of their presumptions i.e. that they (...) are able to already talk meaningfully about ‘something’. We are undertaking a self-reflexive loop towards our already undertaken ‘meaningful’ actions, reflecting inside our concepts on our concepts, trying to find out how our concepts about ‘something’ have come into existence. We are reflecting on our concepts through this ongoing open investigation. We are sketching the ramifications of such a self-reflexive loop for epistemology as well as for the main research areas within cognitive science (i.e. language acquisition, perception, consciousness). We are also pointing towards virtual reality in combination with the arts as an awareness aid, helping us in our self-reflexive endeavours. (shrink)

After introducing the concept of compressed sensing as a complementary measurement mode to the classical Shannon-Nyquist approach, I discuss some of the drivers, potential challenges and obstacles to its implementation. I end with a speculative attempt to embed compressed sensing as an enabling methodology within the emergence of data-driven discovery. As a consequence I predict the growth of non-nomological sciences where heuristic correlations will find applications but often bypass conventional pure basic and use-inspired basic research stages due to (...) the lack of verifiable hypotheses.

I propose that the fundamental challenge Berkeley left realists is to account for experiences’ ability to present items as mind-independent, consistent with the claim that experiences always present themselves among the items of awareness. By exploring two ways of responding to this challenge, and ruling out the second, I hope to show that realists aiming to secure a role for experiences in grounding our grasp of mind-independence need to adopt a specific view of perceptual experience. They must take experiences to (...) have translucent aspects, and accord such aspects an essential role in presenting us with a mind-independent world. (shrink)

We can anticipate what is yet to happen, remember what has already happened, but our immediate experience is confined to the present, the here and now. So much seems common sense. So much so that it is no surprise to see Thomas Reid, that pre-eminent champion of common sense in philosophy, advocating precisely this position.

One of the goals of computerized tutoring systems is to optimize the learning of facts. Over a hundred years of declarative memory research have identified two robust effects that can improve such systems: the spacing and the testing effect. By making optimal use of both and adjusting the system to the individual learner using cognitive models based on declarative memory theories, such systems consistently outperform traditional methods. This adjustment process is driven by a continuously updated estimate of the rate of (...) forgetting for each item and learner on the basis of the learner's accuracy and response time. In this study, we investigated to what extent these estimates of individual rates of forgetting are stable over time and across different materials. We demonstrate that they are stable over time but not across materials. Even though most theories of human declarative memory assume a single underlying rate of forgetting, we show that, in practice, it makes sense to assume different materials are forgotten at different rates. If a computerized, adaptive fact-learning system allowed different rates of forgetting for different materials, it could adapt to individual learners more readily. (shrink)

I apply the Method of Phenomenal Contrast to examples involving aesthetic experience and sensory illusion. While the method can provide reasons to prefer one form of content hypothesis over others, it may be of no help in answering substantive questions about the nature and structure of such content. I suggest that successful application of the method can leave us with a difficult question. Why would a sensory system have the function of representing a property that it cannotdetect?

When I was revising _Sensory Qualities_ there was a period of about a year when I set the manuscript aside and did other things. When I returned to it I found that certain portions of the argument had collapsed of their own weight, like an old New England barn, and could be carted off the premises without compunction. Other parts were wobbling on their foundation, while some had weathered well and seemed nice and solid. My revision strategy was simple: I (...) kept just the nice solid bits, thinking that I could go back and work on the wobbly portions later. (shrink)

Ghost variables are variables in program languages that do not correspond to physical entities. This special issue, based on a panel on “Race as a Ghost Variable” at the 2017 Meeting of the Society for Social Studies of Science, traces ideas of “race” in particular niches of science, technology, and medicine where it is submerged and disavowed, yet wields power. Each paper is a case study exploring ghosts that emerge through the resonance among things as heterogeneous as hair patterns, hormone (...) levels, food tastes, drug use, clinic locations, proximity to disaster, job classifications, and social belonging and suspicion, all of which vibrate with meanings accumulated over long racial histories. Together, the papers further elaborate methods and analytic models for identifying the operations of race—the relations and processes that make it, the effects that it has. A chief appeal of the metaphor of the ghost is that it brings the importance of history to the fore. Ghosts are simultaneously history and the present, not just an accretion of earlier experiences, but the palimpsest left when one tries to erase them. Sometimes faint and hard to discern, sometimes rambunctious and disruptive, ghosts refuse our attempts to simply move on. (shrink)

Research and engineering in the quantum domain involve long chains of activity involving theory development, hypothesis formation, experimentation, device prototyping, device testing, and many more. At each stage multiple paths become possible, and of the paths pursued, the majority will lead nowhere. Our quantum metascience approach provides a strategy which enables all stakeholders to gain an overview of those developments along these tracks, that are relevant to their specific concerns. It provides a controlled vocabulary, built out of terms that are (...) designed to be maximally comprehensible to all groups of stakeholders and across all the sub-fields of the quantum domain.

AI-enabled devices are more intelligent and capable of doing a specific task which saves a lot of resources (...) and time. Different approaches are available in the existing literature to tackle diverse issues of real life based on AI and IoT systems. The role of decision-making has its own importance in the AI-enabled and IoT systems. In-depth knowledge of the existing literature is dire need of the research community to summarize the literature in effective way by which practitioners and researchers can benefit from the prevailing proofs and suggest new solutions for solving a particular problem of AI-enabled sensing and decision-making for the IoT system. To facilitate research community, the proposed study presents a systematic literature review of the existing literature, organizes the evidences in a systematic way, and then analyzes it for future research. The study reported the literature of the last 5 years based on the research questions, inclusion and exclusion criteria, and quality assessment of the selected study.

Several metabolites serve as substrates for histone modifications and communicate changes in the metabolic environment to the epigenome. Technologies such as metabolomics and proteomics have allowed us to reconstruct the interactions between metabolic pathways and histones. These technologies have shed light on how nutrient availability can have a dramatic effect on various histone modifications. This metabolism–epigenome cross talk plays a fundamental role in development, immune function, and diseases like cancer. Yet, major challenges remain in understanding the interactions between cellular metabolism (...) and the epigenome. How the levels and fluxes of various metabolites impact epigenetic marks is still unclear. Discussed herein are recent applications and the potential of systems biology methods such as flux tracing and metabolic modeling to address these challenges and to uncover new metabolic–epigenetic interactions. These systems approaches can ultimately help elucidate how nutrients shape the epigenome of microbes and mammalian cells. (shrink)

According to the Zhuangzi, listening to the music of nature draws the self into the silence required to experience things in their self-arising spontaneity. How does this happen? This essay answers by way of the Yue Ji (Record of Music), where it is said that great music embodies the timeliness of nature. Using both texts, I develop timeliness as the opportune moment, temporal natality, and nature’s memory. Listening to the timely music of nature is shown to be an act of (...) ecological perception that, by releasing time in favor of timeliness, reveals our aesthetic accordance with nature’s own becoming.

This book review is about the French translation of a book by the anthropologist Arturo Escobar that, though it has not been translated into English yet, deserves to be known by English readers. This book is quite important since it allows one to understand occidental, capitalist and modern hegemony not only as an economic domination but above all as a cultural, epistemological and ontological colonisation. Indeed, according to Escobar, this domination takes its roots in the Occident’s ontology which translates into (...) hegemonic practices that are concrete threats to the other worlds and their dwellers. Thus, Escobar highlights the deep link between ontologies and practices and argues for a new field of study he calls political ontology or ontological politics. To accompany the proposition of a shift from a universal nature to a pluriverse composed of many worlds, Escobar does not only undermine the prejudices of modernity but also puts forward the relational ontologies from indigenous communities of Latin America that concretely resist colonisation, underlining the ontological dimension of their struggles. Such a framework enables one to overcome or at least minimize the distinction between theory and practice. (shrink)

In this paper, we identify and discuss some of the ethical problems associated with digital sensors used to detect water contamination and air pollution in the United States. Such safety devices are often deployed unsystematically and with questionable efficacy, thereby structuring the life chances of people in unequal ways. Whereas most technological infrastructures are hidden from view . or at least from active awareness . until they cease to function, those infrastructures meant to monitor and/or regulate largely "invisible" public health (...) dangers resist public awareness even when they fail. Because such detection systems tend to indivi-dualize responsibility for reducing risk, the systems may normalize and perhaps exacerbate root problems of contamination and unequal exposure. One ethical challenge is to render such systems and their failures legible. (shrink)

When dealing with biological communication and information, unifying concepts are necessary in order to couple the different “codes” that are being inductively “cracked” and defined at different emergent and “deemergent” levels of the biological hierarchy. In this paper I compare the type of biological information implied by genetic information with that implied in the concept of “quorum sensing” (which refers to a prokaryotic cell-to-cell communication system) in order to explore if such integration is being achieved. I use the Lux (...) operon paradigm and the Vibrio fischeri – Euprymna scolopes symbiotic partnership to exemplify the emergence of informational contexts along the biological hierarchy (from molecules to ecologies). I suggest that the biosemiotic epistemological framework can play an integrative role to overcome the limits of dyadic mechanistic descriptions when relating the different emergent levels. I also emphasise that the realisation ofbiology as being a “science of sensing” and the new importance that is being ascribed to the “context” in experimental biology corroborate past claims ofbiosemioticians about a shift from a focus on information (as a material agent of causality) towards a focus on the world of signification.

The importance of electrical signalling in bacteria is an emerging paradigm. Bacillus subtilis biofilms exhibit electrical communication that regulates metabolic activity and biofilm growth. Starving cells initiate oscillatory extracellular potassium signals that help even the distribution of nutrients within the biofilm and thus help regulate biofilm development. Quorum sensing also regulates biofilm growth and crucially there is convergence between electrical and quorum sensing signalling axes. This makes B. subtilis an interesting model for cell signalling research. SpoOF is predicted (...) to act as a logic gate for signalling pathway convergence, raising interesting questions about the functional nature of this gate and the relative importance of these disparate signals on biofilm behaviour. How is an oscillating signal integrated with a quorum signal? The model presented offers rich opportunities for future experimental and theoretical modelling research. The importance of direct cell‐to‐cell electrical signalling in prokaryotes, so characteristic of multicellular eukaryotes, is also discussed. (shrink)

River segmentation of remote sensing images is of important research significance and application value for environmental monitoring, disaster warning, and agricultural planning in an area. In this study, we propose a river segmentation model in remote sensing images based on composite attention network to solve the problems of abundant river details in images and the interference of non-river information including bridges, shadows, and roads. To improve the segmentation efficiency, a composite attention mechanism is firstly introduced in the central (...) region of the network to obtain the global feature dependence of river information. Next, in this study, we dynamically combine binary cross-entropy loss that is designed for pixel-wise segmentation and the Dice coefficient loss that measures the similarity of two segmentation objects into a weighted one to optimize the training process of the proposed segmentation network. The experimental results show that compared with other semantic segmentation networks, the evaluation indexes of the proposed method are higher than those of others, and the river segmentation effect of CoANet model is significantly improved. This method can segment rivers in remote sensing images more accurately and coherently, which can meet the needs of subsequent research. (shrink)

In the late nineteenth century, Jagadish Chandra Bose devised millimeter- and micro-wave experiments to record responses of plants to electromagnetic stimuli. Based on these experiments, Bose conceptualized his thesis of the unity of living and nonliving entities through their different sensitivities to electromagnetic vibrations. By relating Bose’s thesis of the unity of life based on electromagnetic vibrations to Alfred North Whitehead’s process philosophy and N. Katherine Hayles’s work on the cognitive nonconscious, I argue for a processual media theory that connects (...) both human and plant intelligence to electromagnetic signaling. In doing so, I examine how discourses about different living bodies (plants, animals, humans) variously sensing their environments are formulated into claims about which species have what degree of cognitive capability and intelligence. I trace the influence of Bose’s work on the ecological thinking of the 1970s espoused by cyberneticists and countercultural environmentalists and on contemporary plant neurobiologists who are closely working with Internet of Things designers and researchers. This enables me to emerge with an understanding of electrosensitivity that acknowledges that there is more to the intensities and energies of signals than mere data and that such infra-informatic signals can create both capacities and incapacities, capabilities and debilities, in bodies.
