Download or read book Search for the Decay K L 0 nu bar nu at the J PARC KOTO Experiment written by Kota Nakagiri and published by Springer Nature. This book was released on 2020-08-20 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reports on a new result from the KL→π0νν search at the J-PARC KOTO experiment, which sets an upper limit of 3×10-9 for the branching fraction of the decay at the 90% confidence level, improving the previous best limit by an order of magnitude. To explain the matter–antimatter asymmetry in the universe, still unknown new physics beyond the standard model (SM) that breaks CP symmetry is necessary. The rare decay of a long-lived neutral K meson, KL→π0νν, is a CP-violating decay. It is an excellent probe to search for new physics because new physics can contribute to the decay and change its branching fraction, while the SM is as small as 3×10-11. However, it is extremely difficult to search for because all of the decay products are neutral and two neutrinos are undetectable. The KL→π0νν signal is identified by measuring two photons from a π0 with a calorimeter and confirming the absence of any other detectable particles with hermetic veto counters. The book contributes to the analysis of neutron-induced backgrounds which were the dominant background sources in the search. For the background caused by two consecutive hadronic showers in the calorimeter due to a neutron, the author evaluated the background yield using a data-driven approach. For another background caused by an η meson production—η decays two photons—by a neutron that hits a veto counter near the calorimeter, the author developed an original analysis technique to reduce it. The book also contributes to the analysis of the normalization modes (KL→3π0, KL→2π0, KL→2γ) to measure KL yield, the estimation of the signal acceptance based on a simulation, and the evaluation of the trigger efficiency. As a result, significant improvements in the measurement were achieved, and this is an important step in the continuing higher sensitivity search, which can reach new physics with the energy scales up to O(100-1000 TeV).

Download or read book Transnational Japan in the Global Environmental Movement written by Simon Avenell and published by University of Hawaii Press. This book was released on 2018-11-30 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: What motivates people to become involved in issues and struggles beyond their own borders? How are activists changed and movements transformed when they reach out to others a world away? This adept study addresses these questions by tying together local, national, regional, and global historical narratives surrounding the contemporary Japanese environmental movement. Spanning the era of Japanese industrial pollution in the 1960s and the more recent rise of movements addressing global environmental problems, it shows how Japanese activists influenced approaches to environmentalism and industrial pollution in the Asia-Pacific region, North America, and Europe, as well as landmark United Nations conferences in 1972 and 1992. Japan’s experiences with diseases caused by industrial pollution produced a potent “environmental injustice paradigm” that fueled domestic protest and became the motivation for Japanese groups’ activism abroad. From the late 1960s onward Japanese activists organized transnational movements addressing mercury contamination in Europe and North America, industrial pollution throughout East Asia, radioactive waste disposal in the Pacific, and global climate change. In all cases, they advocated strongly for the rights of pollution victims and people living in marginalized communities and nations—a position that often put them at odds with those advocating for the global environment over local or national rights. Transnational involvement profoundly challenged Japanese groups’ understanding of and approach to activism. Numerous case studies demonstrate how border-crossing efforts undermined deeply engrained notions of victimhood in the domestic movement and nurtured a more self-reflexive and multidimensional approach to environmental problems and social activism. Transnational Japan in the Global Environmental Movement will appeal to scholars and students interested in the development of civil society, social movements, and environmentalism in contemporary Japan; grassroots inter-Asian connections in the postwar period; and the ways Asian countries and their citizens have shaped and been influenced by global issues like environmentalism.
Download or read book String Theory and the Real World written by Gordon Kane and published by Morgan & Claypool Publishers. This book was released on 2017-03-27 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book attempts to explain why 'string theory' may provide the comprehensive underlying theory that describes and explains our world. It is an enthusiastic view of how compactified string/M-theories (plus data that may be reachable) seem to have the possibilities of leading to a comprehensive underlying theory of particle physics and cosmology, perhaps soon. We are living in a hugely exciting era for science, one during which it may be possible to achieve a real and true understanding of our physical world.
Download or read book Japan s China Policy written by Linus Hagström and published by Routledge. This book was released on 2005-03-09 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Japan's China Policy understands Japan's foreign policy in terms of power - one of the most central concepts of political analysis. It contributes a fresh understanding to the subject by developing relational power as an analytical framework and by applying it to significant issues in Japan's China policy: the negotiations for a bilateral investment protection treaty and the disputed Pinnacle (Senkaku/Diaoyu) Islands. Hagström demonstrates that Japan exerted power over China in such divergent empirical settings for the most part by using civilian instruments positively, defensively and through non-action. Given that Japan's foreign policy is often portrayed rather enigmatically in terms of power, the unique contribution of Japan's China Policy is to demonstrate how to analyze power aspects of Japan's foreign policy in a more coherent fashion. This revealing approach to Japan's foreign policy will be of huge interest to anyone studying Japanese politics, foreign policy or international relations.
Download or read book Japan s Reluctant Realism written by M. Green and published by Springer. This book was released on 2001-05-17 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Japan's Reluctant Realism , Michael J. Green examines the adjustments of Japanese foreign policy in the decade since the end of the Cold War. Green presents case studies of China, the Korean peninsula, Russia and Central Asia, Southeast Asia, the international financial institutions, and multilateral forums (the United Nations, APEC, and the ARF). In each of these studies, Green considers Japanese objectives; the effectiveness of Japanese diplomacy in achieving those objectives; the domestic and exogenous pressures on policy-making; the degree of convergence or divergence with the United States in both strategy and implementation; and lessons for more effective US - Japan diplomatic cooperation in the future. As Green notes, its bilateral relationship with the United States is at the heart of Japan's foreign policy initiatives, and Japan therefore conducts foreign policy with one eye carefully on Washington. However, Green argues, it is time to recognize Japan as an independent actor in Northeast Asia, and to assess Japanese foreign policy in its own terms.
Download or read book Wild Fruits Composition Nutritional Value and Products written by Abdalbasit Adam Mariod and published by Springer. This book was released on 2021-01-19 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild fruits play an important role in mitigating hunger in the developing world. As a sustainable and natural food source in rural areas, these fruits have a strong effect on regional food security and poverty alleviation. This makes the utilization of wild foods incredibly important for native populations both in terms of food security and economics. There are many traditional methods for wild fruit harvesting, indigenous tree and plant domestication and cultivation passed down through generations that are sustainable and economically viable, ultimately contributing to a better quality of life for large sections of the developing world. To date there has not been a reference work focusing on the full scope of wild fruits from their growth and chemical makeup to their harvest, distribution, health effects and beyond. Wild Fruits: Composition, Nutritional Value and Products adequately fills this gap, expansively covering the utilization of multi-purpose wild fruits in regions worldwide. Effects on quality of life, food security, economics and health are extensively covered. Over 31 wild fruit species are examined, with individual chapters focusing on each species' phytochemical constituents, bioactive compounds, traditional and medicinal uses and chemical composition. Harvest, post-harvest and consumption methods are covered for each, as are their overall effect on the food security and economics of their native regions. This book is essential for researchers in search of a comprehensive singular source for the chemical makeups and cultivation of indigenous wild fruits and their many benefits to their native regions.

Download or read book Frontiers of Fundamental Physics written by M. Barone and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Olympia conference Frontiers of Fundamental Physics was a gathering of about hundred scientists who carryon their research in conceptually important areas of physical science (they do "fundamental physics"). Most of them were physicists, but also historians and philosophers of science were well represented. An important fraction of the participants could be considered "heretical" because they disagreed with the validity of one or several fundamental assumptions of modern physics. Common to all participants was an excellent scientific level coupled with a remarkable intellectual honesty: we are proud to present to the readers this certainly unique book. Alternative ways of considering fundamental matters should of course be vitally important for the progress of science, unless one wanted to admit that physics at the end of the XXth century has already obtained the final truth, a very unlikely possibility even if one accepted the doubtful idea of the existence of a "final" truth. The merits of the Olympia conference should therefore not be judged a priori in a positive or in a negative way depending on one's refusal or acceptance, respectively, but considered after reading the actual of basic principles of contemporary science, new proposals and evidences there presented. They seem very important to us.
