Critical Junctions by Don Kalb,Herman Tak Pdf

"A book about theory and method in the humanities and social sciences. It reacts to what has become known as the "cultural turn," a shift toward semiotics, discourse, and representations and away from other sorts of determinations that started in the early 1980s and that has dominated social thinking for a long string of years. The book is based in a reconsideration of the meeting of two disciplines that helped to launch the cultural turn: anthropology and history. Specifically, it criticizes the ideas of hermeneutics and "thick description" (Clifford Geertz) that have come to play a key role in the encounter of anthropology and history and then in the cultural turn. It led to the renewed cherishing of what Gupta and Ferguson have called paradigms of "peoples and places," saturated pictures of universes, both small and large, of meaning ina more of less frozen standstill-an intellectual precursor to the cultural xenophobia of our times. Against this, the present book embraces praxis and "critical junctions": the connections in space (in and out of a relations of power and dependency, and what Eric Wolf has called the "interstitial relations" between apparently separate institutional domains. In this way the book adds to the current revival of institutionally based "global ethnography," which studies "up and outward" (the journal of Ethnography is a good example)."--Preface

Quantum Tunneling of Josephson Vortices in High-Impedance Long Junctions by Wildermuth, Matthias Micha Pdf

In the last decades, superconducting devices have emerged as a promising platform for quantum technologies, including quantum sensing and quantum computing. Their key elements are Josephson junctions, which allow for coherent supercurrent tunneling between two weakly linked superconductors. If such a junction is extended in one direction to a long junction, the superconducting phase difference can vary in space and time and may allow for quantized phase windings that drive supercurrent vortices.

Junctions by Mandishona, Daniel Pdf

Junctions is Daniel Mandishona’s second collection of short stories, following White Gods Black Demons (Weaver Press, 2009). Again, he quarries the richness and variety of Zimbabwean lives to deliver characters and narratives spanning the social spectrum: political ambition and violence; beggars on city streets; family disputes at funerals; rural journeys peppered with mishaps; corrupt policemen and born-again prophets; bus accidents, and township tailors. But if his subjects reect grim realities, Mandishona’s treatment of his characters is achieved with a wonderful sardonic irony, capacious enough to give even the worst offenders a large humanity. The book concludes with Edmore Chidzonga, an unemployed graduate, reflecting on the new dispensation promised by the 2017 change of national leadership: He remembered how his late grandfather often told him that tsuro haipone rutsva kaviri; a hare can only escape a bush re once. He had spent six years protesting. … For the first time, he felt he had no future.

Advances in Superconductivity VII by Kaoru Yamafuji,Tadataka Morishita Pdf

The field of high-temperature superconductivity has encouraged an inter disciplinary approach to research. It has required significant cooperation and collaboration among researchers, each of whom has brought to it a rich variety of experience from many other fields. Recently, great improvements have been made in the quality of research. The subject has matured and been launched into the next stage through the resonance between science and technology. The current progress of materials processing and engineering in this field is analogous to that previously seen in the development of semiconductors. These include the appearance of materials taking the place of YBa2Cu307 owing to their improved properties (higher critical temperatures and stronger flux pin ning) in which rare earth ions with large radii (La, Nd, Sm) substitute for Y; the development of technology enabling growth control on the nanometer scale; and precise and reproducible measurements that can be used as rigorous tests of theoretical models, which in turn are expected to lead to the develop ment of new devices. For further progress in high-T research, academics and c technologists must pool their knowledge and experience. I hope that this volume will promote that goal by providing the reader with the latest results of high-temperature superconductor research and will stimulate further discussion and collaboration.

Blood and Fire by Sharryn Kasmir,August Carbonella Pdf

Based on long-term fieldwork, six vivid ethnographies from Colombia, India, Poland, Spain and the southern and northern U.S. address the dwindling importance of labor throughout the world. The contributors to this volume highlight the growing disconnect between labor struggles and the advancement of the greater common good, a phenomenon that has grown since the 1980s. The collection illustrates the defeat and unmaking of particular working classes, and it develops a comparative perspective on the uneven consequences of and reactions to this worldwide project. Blood and Fire charts a course within global anthropology to address the widespread precariousness and the prevalence of insecure and informal labor in the twenty-first century.

Superconducting Quantum Electronics by Volkmar Kose Pdf

With the surprising discovery of superconductivity at temperatures above 100 K, this field was not only brought into the public eye, but also stimulated research in universities, scientific institutions and industry, thus continuing the fascinating development which began with the discovery of the Josephson effect in the sixties. Cryoelectronics has become a special branch of cryophysics and cryotechnics and today plays a prominent role whenever high resolution and precision measurements are required. Motivated by this development, seven years ago scientists working in cryoelectronics in the Federal Republic of Germany felt the necessity for regular meetings allowing a free exchange of ideas and results achieved. Seminars under the title of "Kryoelektronische Bauelemente" were held for the first time at the Physikalisch-Technische Bundesanstalt in Braunschweig in 1982 on the occasion of the 100th anniversary of the birth of Walther MeiBner, a pioneer in superconductivity. Since then, meetings have been held every year at different venues in Germany. It is now felt that the status of this field necessitates a review of the results of the past, a description of the current state of the art, and a discussion of future perspectives. This book, entitled SUPERCONDUCTING QUANTUM ELECTRONICS is a collection of invited lectures and contributions which will inform the reader on the most interesting problems involving fundamentals, sensitive detectors and precision metrology being studied by different groups.

Macroscopic Quantum Coherence and Quantum Computing by Dmitri V. Averin,Berardo Ruggiero,Paolo Silvestrini Pdf

This volume is an outgrowth of the Second International Workshop on Macroscopic Quantum Coherence and Computing held in Napoli, Italy, in June 2000. This workshop gathered a number of experts from the major Universities and Research Institutions of several countries. The choice of the location, which recognizes the role and the traditions of Naples in this field, guaranteed the participants a stimulating atmosphere. The aim of the workshop has been to report on the recent theoretical and experimental results on the macroscopic quantum coherence of macroscopic systems. Particular attention was devoted to Josephson devices. The correlation with other atomic and molecular systems, exhibiting a macroscopic quantum behaviour, was also discussed. The seminars provided both historical overview and recent theoretical ground on the topic, as well as information on new experimental results relative to the quantum computing area. The first workshop on this topic, held in Napoli in 1998, has been ennobled by important reports on observations of Macroscopic Quantum Coherence in mesoscopic systems. The current workshop proposed, among many stimulating results, the first observations of Macroscopic Quantum Coherence between macroscopically distinct fluxoid states in rf SQUIDs, 20 years after the Leggett's proposal to experimentally test the quantum behavior of macroscopic systems. Reports on observations of quantum behaviour in molecular and magnetic systems, small Josephson devices, quantum dots have also been particularly stimulating in view of the realization of several possible q-bits.
