Dynamics of Asymmetric Dissipative Systems

From Traffic Jam to Collective Motion

By: Yuki Sugiyama

This book provides the dynamics of non-equilibrium dissipative systems with asymmetric interactions (Asymmetric Dissipative System; ADS). Asymmetric interaction breaks "the law of action and reaction" in mechanics, and results in non-conservation of the total momentum and energy. In such many-particle systems, the inflow of energy is provided and the energy flows out as dissipation. The emergences of non-trivial macroscopic phenomena occur in the non-equilibrium energy balance owing to the effect of collective motions as phase transitions and bifurcations. ADS are applied to the systems of self-driven interacting particles such as traffic and granular flows, pedestrians and evacuations, and collective movement of living systems. The fundamental aspects of dynamics in ADS are completely presented by a minimal mathematical model, the Optimal Velocity (OV) Model. Using that model, the basics of mathematical and physical mechanisms of ADS are described analytically with exact results. The application of 1-dimensional motions is presented for traffic jam formation. The mathematical theory is compared with empirical data of experiments and observations on highways. In 2-dimensional motion pattern formations of granular media, pedestrians, and group formations of organisms are described. The common characteristics of emerged moving objects are a variety of patterns, flexible deformations, and rapid response against stimulus. Self-organization and adaptation in group formations and control of group motions are shown in examples. Another OV Model formulated by a delay differential equation is provided with exact solutions using elliptic functions. The relations to soliton systems are described. Moreover, several topics in ADS are presented such as the similarity between the spatiotemporal patterns, violation of fluctuation dissipation relation, and a thermodynamic function for governing the phase transition in non-equilibrium stationary states.

Enzymatic Bioelectrocatalysis

By: Kenji Kano,Osamu Shirai,Yuki Kitazumi,Kento Sakai,Hong-Qi Xia

This book covers the fundamental aspects of the electrochemistry and redox enzymes that underlie enzymatic bioelectrocatalysis, in which a redox enzyme reaction is coupled with an electrode reaction. Described here are the basic concept and theoretical aspects of bioelectrocatalysis and the various experimental techniques and materials used to study and characterize related problems. Also included are the various applications of bioelectrocatalysis to bioelectrochemical devices including biosensors, biofuel cells, and bioreactors. This book is a unique source of information in the area of enzymatic bioelectrocatalysis, approaching the subject from a cross-disciplinary point of view.

Japan's Comfort Women

Japan's Comfort Women

By: Yuki Tanaka

Japan's Comfort Women tells the harrowing story of the "comfort women" who were forced to enter prostitution to serve the Japanese Imperial army, often living in appalling conditions of sexual slavery. Using a wide range of primary sources, the author for the first time links military controlled prostitution with enforced prostitution. He uncovers new and controversial information about the role of the US' occupation forces in military controlled prostitution, as well as the subsequent "cover-up" of the existence of such a policy. This groundbreaking book asks why US occupation forces did little to help the women, and argues that military authorities organised prostitution to prevent the widespread incidence of GI rape of Japanese women, and to control the spread of sexually transmitted diseases.

Japan's Early Experience of Contract Management in the Treaty Ports

By: Yuki Allyson Honjo

This is the first in-depth study of the early trial-and-error experiences of contracting between Japanese and western merchants trading in the Japanese Treaty Ports in the eighteen year period immediately following the opening of the ports in 1859. Fundamental to the equation were the inevitable east-west cultural and legal ambiguities that impacted on the traders. The learning curve for both westerners and Japanese regarding the nature and application of western contracting law was predictably difficult, tortuous and open to constant misunderstanding. Nevertheless, it was within such a framework that the principal benchmarks for trade with Japan were set down and which, in essence, have lasted to the present day.

Sexual Abuse and Education in Japan

In the (Inter)National Shadows

By: Robert O'Mochain,Yuki Ueno

Bringing together two voices, practice and theory, in a collaboration that emerges from lived experience and structured reflection upon that experience, O’Mochain and Ueno show how entrenched discursive forces exert immense influence in Japanese society and how they might be most effectively challenged. With a psychosocial framework that draws insights from feminism, sociology, international studies, and political psychology, the authors pinpoint the motivations of the nativist right and reflect on the change of conditions that is necessary to end cultures of impunity for perpetrators of sexual abuse in Japan. Evaluating the value of the #MeToo model of activism, the authors offer insights that will encourage victims to come out of the shadows, pursue justice, and help transform Japan’s sense of identity both at home and abroad. Ueno, a female Japanese educator and O’Mochain, a non-Japanese male academic, examine the nature of sexual abuse problems both in educational contexts and in society at large through the use of surveys, interviews, and engagement with an eclectic range of academic literature. They identify the groups within society who offer the least support for women who pursue justice against perpetrators of sexual abuse. They also ask if far-right ideological extremists are fixated with proving that so called “comfort women” are higaisha-buru or “fake victims.” Japan would have much to gain on the international stage were it to fully acknowledge historical crimes of sexual violence, yet it continues to refuse to do so. O’Mochain and Ueno shed light on this puzzling refusal through recourse to the concepts of ‘international status anxiety’ and ‘male hysteria.’ An insightful read for scholars of Japanese society, especially those concerned about its treatment of women.

Quantum Oscillations and Charge-Neutral Fermions in Topological Kondo Insulator YbB12

By: Yuki Sato

Electronic state of every solid is basically classified into two categories according to its electrical responses: insulator or metal. A textbook of modern solid state physics explains that shape of a Fermi surface plays a key role in most physical properties in metals. One of the well-established experimental methods to detect a Fermi surface is measurement of quantum oscillations that is a periodic response of physical quantities with respect to external magnetic fields. As insulators do not host Fermi surface, it is believed that they do not exhibit any quantum oscillations. This book presents a comprehensive review of recent observations of quantum oscillations in the Kondo insulators, SmB6 and YbB12, and discusses how the observations are demonstrated by a newly proposed mechanism where emergent charge-neutral fermions exhibit quantum oscillations instead of bare electrons. It also focuses on topological properties of Kondo insulators, and demonstrates that YbB12 hosts a surface metallic conduction owing to its non-trivial band structure. Further it presents the experiments of specific heat and thermal conductivity in YbB12 down to ultra-low temperature to discuss the possible low-energy excitations from a Fermi surface of neutral fermions. The demonstrated gapless and itinerant fermionic excitations, that is the significant contribution from charge neutral fermions, violates Wiedemann-Franz law. The discoveries point out a highly unconventional phase of quantum state—electrically insulating but thermally metallic—realized in the bulk of topological Kondo insulators.
