Matrix Functions of Bounded Type: An Interplay Between Function Theory and Operator Theory

By: Raúl E. Curto,In Sung Hwang,Woo Young Lee

In this paper, the authors study matrix functions of bounded type from the viewpoint of describing an interplay between function theory and operator theory. They first establish a criterion on the coprime-ness of two singular inner functions and obtain several properties of the Douglas-Shapiro-Shields factorizations of matrix functions of bounded type. They propose a new notion of tensored-scalar singularity, and then answer questions on Hankel operators with matrix-valued bounded type symbols. They also examine an interpolation problem related to a certain functional equation on matrix functions of bounded type; this can be seen as an extension of the classical Hermite-Fejér Interpolation Problem for matrix rational functions. The authors then extend the H∞-functional calculus to an H∞¯¯¯¯¯¯¯¯¯+H∞-functional calculus for the compressions of the shift. Next, the authors consider the subnormality of Toeplitz operators with matrix-valued bounded type symbols and, in particular, the matrix-valued version of Halmos's Problem 5 and then establish a matrix-valued version of Abrahamse's Theorem. They also solve a subnormal Toeplitz completion problem of 2×2 partial block Toeplitz matrices. Further, they establish a characterization of hyponormal Toeplitz pairs with matrix-valued bounded type symbols and then derive rank formulae for the self-commutators of hyponormal Toeplitz pairs.

Discovering the Book of Changes - a Journey

By: Graham Taylor,University Lecturer in Mathematical Biology Graham Taylor

Here is a fresh, fascinating look at the Book of Changes, tracing the mythical and legendary rulers, along with the Taoist and Confucian origins within it, and considering the role of each in the making of the Book of Changes. Essentially, it is offered to the reader as a detailed reappraisal of the wisdom contained within the ancient text. Whether you are old or new to the Book of Changes you will gain much from the practical advice contained in this in-depth, well-researched work. You will discover the Book of Changes is a mirror into yourself and as such, you will learn, through your own inner mirror, to 'know thyself'. Through such a process, you will also learn to enhance your psyche, intuition and instincts, all neglected since the rise of modernity. You will discover, for the first time, the 'true' meaning of colour within the Book of Changes, according to the ancient Taoist, and its practical use in daily life. In addition, you will find out about the workings of an ancient magic charm, in trigram form, also for the first time, which opens up possibilities that a magical formula lies within the Book of Changes. It is a work you will want to reread.

Veterans and Agent Orange

Update 2008

By: Institute of Medicine,Board on Population Health and Public Health Practice,Committee to Review the Health Effects in Vietnam Veterans of Exposure to Herbicides (Seventh Biennial Update)

From 1962 to 1971, the U.S. military sprayed herbicides over Vietnam to strip the thick jungle canopy that could conceal opposition forces, to destroy crops that those forces might depend on, and to clear tall grasses and bushes from the perimeters of U.S. base camps and outlying fire-support bases. In response to concerns and continuing uncertainty about the long-term health effects of the sprayed herbicides on Vietnam veterans, Veterans and Agent Orange provides a comprehensive evaluation of scientific and medical information regarding the health effects of exposure to Agent Orange and other herbicides used in Vietnam. The 2008 report is the eighth volume in this series of biennial updates. It will be of interest to policy makers and physicians in the federal government, veterans and their families, veterans' organizations, researchers, and health professionals.

Veterans and Agent Orange

Update 2014

From 1962 to 1971, the US military sprayed herbicides over Vietnam to strip the thick jungle canopy that could conceal opposition forces, to destroy crops that those forces might depend on, and to clear tall grasses and bushes from the perimeters of US base camps and outlying fire-support bases. Mixtures of 2,4-dichlorophenoxyacetic acid (2,4-D), 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), picloram, and cacodylic acid made up the bulk of the herbicides sprayed. The main chemical mixture sprayed was Agent Orange, a 50:50 mixture of 2,4-D and 2,4,5-T. At the time of the spraying, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), the most toxic form of dioxin, was an unintended contaminant generated during the production of 2,4,5-T and so was present in Agent Orange and some other formulations sprayed in Vietnam. Because of complaints from returning Vietnam veterans about their own health and that of their children combined with emerging toxicologic evidence of adverse effects of phenoxy herbicides and TCDD, the National Academy of Sciences was asked to perform a comprehensive evaluation of scientific and medical information regarding the health effects of exposure to Agent Orange, other herbicides used in Vietnam, and the various components of those herbicides, including TCDD. Updated evaluations were conducted every two years to review newly available literature and draw conclusions from the overall evidence. Veterans and Agent Orange: Update 2014 is a cumulative report of the series thus far.

Western-Centrism and Contemporary Korean Political Thought

By: Jung In Kang

This book is an outgrowth of critical examination of Western political theory embedded in Western-centrism and the tumultuous ideational processes by which contemporary Korean political theory and reality have intensely interacted (both in convergent and divergent ways) with it. To conduct such examination the book addresses complex and variegated questions regarding Western-centrism: What is Western-centrism? How is Western-centrism to be compared and contrasted with other forms of centrism such as Sinocentrism, capitalism (bourgeois-centrism), patriarchy (male-centrism), and racism (white-centrism)? How has Western-centrism evolved in world history and in the history of Western political thought? How has Western-centrism shaped the evolution of contemporary Korean political thought? What kinds of ill effects has Western-centrism brought about in Korean society and academia? And, ultimately, how can Western-centrism be overcome?

Academic Health Centers

Leading Change in the 21st Century

By: Institute of Medicine,Committee on the Roles of Academic Health Centers in the 21st Century

Academic health centers are currently facing enormous changes that will impact their roles in education, research, and patient care. The aging and diversity of the population will create new health care needs and demands, while rapid advances in technology will fundamentally alter the health care systems' capabilities. Pressures on health care costs, growth of the uninsured, and evidence of quality problems in health care will create a challenging environment that demands change. Academic Health Centers explores how AHCs will need to consider how to redirect each of their roles so they are able to meet the burgeoning challenges of health care and improve the health of the people they serve. The methods and approaches used in preparing health professionals, the relationship among the variety of their research programs and the design of clinical care will all need examination if they are to meet the changing demands of the coming decades. Policymakers will need to create incentives to support innovation and change in AHCs. In response, AHCs will need to increase the level of coordination and integration across their roles and the individual organizations that comprise the AHC if they are to successfully undertake the types of changes needed. Academic Health Centers lays out a strategy to start a continuing and long-term process of change.

Dynamic Korea and Rhythmic Form

By: Katherine In-Young Lee

Winner of the the 2019 Béla Bartók Award for Outstanding Ethnomusicology The South Korean percussion genre, samul nori, is a world phenomenon whose rhythmic form is the key to its popularity and mobility. Based on both ethnographic research and close formal analysis, author Katherine In-Young Lee focuses on the kinetic experience of samul nori, drawing out the concept of dynamism to show its historical, philosophical, and pedagogical dimensions. Breaking with traditional approaches to the study of world music that privilege political, economic, institutional, or ideological analytical frameworks, Lee argues that because rhythmic forms are experienced on a somatic level, they swiftly move beyond national boundaries and provide sites for cross-cultural interaction.

Recapturing a Future for Space Exploration

Life and Physical Sciences Research for a New Era

More than four decades have passed since a human first set foot on the Moon. Great strides have been made in our understanding of what is required to support an enduring human presence in space, as evidenced by progressively more advanced orbiting human outposts, culminating in the current International Space Station (ISS). However, of the more than 500 humans who have so far ventured into space, most have gone only as far as near-Earth orbit, and none have traveled beyond the orbit of the Moon. Achieving humans' further progress into the solar system had proved far more difficult than imagined in the heady days of the Apollo missions, but the potential rewards remain substantial. During its more than 50-year history, NASA's success in human space exploration has depended on the agency's ability to effectively address a wide range of biomedical, engineering, physical science, and related obstacles-an achievement made possible by NASA's strong and productive commitments to life and physical sciences research for human space exploration, and by its use of human space exploration infrastructures for scientific discovery. The Committee for the Decadal Survey of Biological and Physical Sciences acknowledges the many achievements of NASA, which are all the more remarkable given budgetary challenges and changing directions within the agency. In the past decade, however, a consequence of those challenges has been a life and physical sciences research program that was dramatically reduced in both scale and scope, with the result that the agency is poorly positioned to take full advantage of the scientific opportunities offered by the now fully equipped and staffed ISS laboratory, or to effectively pursue the scientific research needed to support the development of advanced human exploration capabilities. Although its review has left it deeply concerned about the current state of NASA's life and physical sciences research, the Committee for the Decadal Survey on Biological and Physical Sciences in Space is nevertheless convinced that a focused science and engineering program can achieve successes that will bring the space community, the U.S. public, and policymakers to an understanding that we are ready for the next significant phase of human space exploration. The goal of this report is to lay out steps and develop a forward-looking portfolio of research that will provide the basis for recapturing the excitement and value of human spaceflight-thereby enabling the U.S. space program to deliver on new exploration initiatives that serve the nation, excite the public, and place the United States again at the forefront of space exploration for the global good.
