Circular economy is a critical approach to realize the coordinated development of society, economy, and ecological environment. Given the fact that urban is a complex system in which human beings integrate material, energy, information, and natural environment and interact and influence each other, reviewing the urban circular economy research and development could benefit for having a better and comprehensive understanding on urban complexity. Mainly based on the Chinese literature studies from 1999 to 2020, this study aims to present an in-depth (...) analysis of the research themes, policy systems, and index system of Chinaʼs urban-scale circular economy, discuss the changes and evolution trends of themes, levels, and perspectives in time series, sort out the policy systems at both the national and local levels, and analyze the design principles and application fields of indicators. Finally, we propose that future development of an urban circular economy should be built based on modern techniques, technologies, and models. The construction of development mechanism on the circular economy should be framed as “government-led, market-driven, legal norms, policy support, technological support, and public participation” and inject concepts such as “Internet +,” “sharing economy,” “Internet of Things,” and “artificial intelligence.”.

_Feminist Interpretations of Thomas Hobbes _features the work of feminist scholars who are centrally engaged with Hobbes’s ideas and texts and who view Hobbes as an important touchstone in modern political thought. Bringing together scholars from the disciplines of philosophy, history, political theory, and English literature who embrace diverse theoretical and philosophical approaches and a range of feminist perspectives, this interdisciplinary collection aims to appeal to an audience of Hobbes scholars and nonspecialists alike. As a theorist whose trademark is a (...) compelling argument for absolute sovereignty, Hobbes may seem initially to have little to offer twenty-first-century feminist thought. Yet, as the contributors to this collection demonstrate, Hobbesian political thought provides fertile ground for feminist inquiry. Indeed, in engaging Hobbes, feminist theory engages with what is perhaps the clearest and most influential articulation of the foundational concepts and ideas associated with modernity: freedom, equality, human nature, authority, consent, coercion, political obligation, and citizenship. Aside from the editors, the contributors are Joanne Boucher, Karen Detlefsen, Karen Green, Wendy Gunther-Canada, Jane S. Jaquette, S. A. Lloyd, Su Fang Ng, Carole Pateman, Gordon Schochet, Quentin Skinner, and Susanne Sreedhar. (shrink)

Previous studies have shown that the motion intention recognition for lower limb prosthesis mainly focused on the identification of performed gait. However, the bionic prosthesis needs to know the next movement at the beginning of a new gait, especially in complex operation environments. In this paper, an upcoming locomotion prediction scheme via multilevel classifier fusion was proposed for the complex operation. At first, two motion states, including steady state and transient state, were defined. Steady-state recognition was backtracking of a completed (...) gait, which would be used as prior knowledge of motion prediction. In steady-state recognition, surface electromyographic and inertial sensors were fused to improve recognition accuracy; five typical locomotion modes were recognized by random forest classifier with over 97.8% accuracy. The transient state was defined as an observation period at the initial stage of upcoming movement, in which only the sEMG signal was recorded due to the limitation of sliding window length. LightGBM classifier was validated to outperform other methods in the accuracy and prediction time of transient-state recognition. Finally, a simplified HMM model based on prior knowledge and observation result was constructed to predict upcoming locomotion. The results indicated that the locomotion prediction was over 91% accuracy. The proposed scheme implements the locomotion prediction at the initial stage of each gait and provides critical information for the gait control of lower limb prosthesis. (shrink)
