This book treats the Stark effect of a hydrogenic atom or ion in a homogeneous electric field. It begins with a thorough review of previous work in this field since 1926. After the Schrödinger equation has been separated with respect to time dependence, centre of mass motion and internal motion, followed by a discussion of its eigenfunctions, the exact development in time of the probability amplitude for a decaying state is obtained by means of a formula analogous to the Fock-Krylov theorem. From this formula one obtains by means of the phase-integral approximation generated from a particular base function non-relativistic formulas for profiles, energies and half-widths of the Stark levels. These formulas are then transformed into formulas expressed in terms of complete elliptic integrals. The formulas thus obtained are used for the calculation of energies and half-widths of 198 different Stark states, which are compared with the corresponding results obtained by other authors with the use of other methods. An analysis of this material indicates that the energy values obtained by the phase-integral method are at least as accurate as those obtained by other methods in more than half of the 198 cases. The book presents one of the most comprehensive asymptotic treatments of the Stark effect in atomic hydrogen that have been published./a

Since his undergraduate days in Cambridge, George Yeo has spoken and written much in and out of government. Many remember the things which he said or wrote years ago. This book is a compilation of some of his best speeches and writings which were selected by Asad Latif and Lee Huay Leng in consultation with him.The book has a rather unusual title because there are many aspects to George Yeo which makes him difficult to classify. As a student leader, he was radical but conciliatory. In the Singapore Armed Forces, he was atypical, moving from the Army to the Air Force before becoming Director of Joint Operations and Planning. In politics, he is fondly remembered by artists, journalists, doctors, businessmen and foreign diplomats, and by his colleagues and constituents. His own staff said he had a curious mind. They complained that he rarely used the drafts which they had prepared for him.George Yeo describes himself as a Taoist even though he is a Roman Catholic and is now on the Papal staff. Buddhists are surprised he championed the revival of Nalanda University as an international project. He remains close to Singaporeans of different races and religions even though he has a deep sense of his own ancestral roots and religion. In politics, he has been described both as a liberal and a conservative. In his Parliamentary maiden speech, he spoke of the importance of democracy but has repeated many times that democracy is only a means and not an end in itself. He has a deep interest in history which partly explains his seeing the re-emergence of China and India earlier than most others.The bonsai and the banyan are metaphors he uses for Singapore. Singapore is a city-state and must never have an inflated view of itself. The bonsai describes Singapore modestly, but he adds that the bonsai can be intensely interesting and valuable. The banyan provides shade and we are grateful for it, but too much makes us weak. As for the Tao, that perhaps is what gives unity to his many interests.

The book aims to provide both comprehensive reviews of the classical methods and an introduction to new developments in medical statistics. The topics range from meta analysis, clinical trial design, causal inference, personalized medicine to machine learning and next generation sequence analysis. Since the publication of the first edition, there have been tremendous advances in biostatistics and bioinformatics. The new edition tries to cover as many important emerging areas and reflect as much progress as possible. Many distinguished scholars, who greatly advanced their research areas in statistical methodology as well as practical applications, also have revised several chapters with relevant updates and written new ones from scratch.The new edition has been divided into four sections, including, Statistical Methods in Medicine and Epidemiology, Statistical Methods in Clinical Trials, Statistical Genetics, and General Methods. To reflect the rise of modern statistical genetics as one of the most fertile research areas since the publication of the first edition, the brand new section on Statistical Genetics includes entirely new chapters reflecting the state of the art in the field.Although tightly related, all the book chapters are self-contained and can be read independently. The book chapters intend to provide a convenient launch pad for readers interested in learning a specific topic, applying the related statistical methods in their scientific research and seeking the newest references for in-depth research.

In the last decade, the familiar problem of the regress of reasons has returned to prominent consideration in epistemology. And with the return of the problem, evaluation of the options available for its solution is begun anew. Reason’s regress problem, roughly put, is that if one has good reasons to believe something, one must have good reason to hold those reasons are good. And for those reasons, one must have further reasons to hold they are good, and so a regress of reasons looms. In this new study, Aikin presents a full case for infinitism as a response to the problem of the regress of reasons. Infinitism is the view that one must have a non-terminating chain of reasons in order to be justified. The most defensible form of infinitism, he argues, is that of a mixed theory – that is, epistemic infinitism must be consistent with and integrate other solutions to the regress problem.

Plant molecular biology came to the fore in the early 1980s and there has been tremendous growth in the subject since then. The study of plant genes and genomes and the development of techniques for the incorporation of novel or modified genes into plants eventually led to the commercialisation of genetically modified (GM) crops in the mid-1990s. This was seen as the start of a biotechnological revolution in plant breeding. However, plant biotechnology has become one of the hottest debates of the age and, in Europe at least, one of the greatest challenges that plant scientists have ever faced. This book covers the history and development of the science and techniques that underpin plant biotechnology. It describes the GM crops that are or have been grown commercially around the world, including failures as well as successes, and the new varieties that are being developed. The safety record of GM crops is reviewed together with the legislation that has been adopted to cover their use. The book also deals with the concerns of consumers, the GM crop debate and the prospects for the technology. In the second edition, sections on current GM crops and future developments in plant biotechnology have been greatly expanded, while those on techniques, legislation and the GM crop debate have also been updated. The book is a concise, comprehensive and readable study that is accessible to a general readership with a scientific background but also provides useful information for the specialist.

This is a biography of Dr Felicia Wu.Felicia was a scientist with a successful career in cancer research, but what marked the most extraordinary aspect about her life was her journey as a truly brave cancer patient and an incredibly determined cancer fighter. Originally, this book was intended to be an autobiography written and narrated by Felicia herself. She wanted to share with other cancer sufferers her 13 long years of experience fighting cancer to prepare them for the side effects and uncertainties of the treatment, and also to encourage them to brace and face their own treatment without fear. What she did not realize then was that her time was ticking away, and her life trickling off quickly. Writing her own autobiography proved to be an impossible task.Felicia succumbed to the prolonged battle and departed from this world. Her husband, Dr Cheng-Wen Wu, finished the uncompleted task of writing the book in loving memory of her. The biography of Felicia, originally published in Chinese edition, has been recommended as a reading model for students in schools and was nominated for an award in Taiwan. Felicia's story had also inspired the production of a documentary film entitled, “A Passion for Life,” funded and sponsored by The American Cancer Society. This biography of Felicia in English edition, painstakingly translated by Dr Cheng-Wen Wu and his collaborating translator, Ms Annie Chen, will certainly live up to its original premise as an inspiration to touch more lives and as a source of strength to all who encounter difficulty, disappointment and hurt at any point of their lives.

India is emerging as one of the economic giants of the world, and is gaining international influence and global leadership as the world's largest democracy. India's performance will have far-reaching consequences on whether the economic awakening of the country, which began more than two decades ago, can become a good model to be emulated by other developing economies.This book is a collection of policy papers and data-sets for the 35 states and federal territories of India. With a comprehensive approach to competitiveness, the research done by Asia Competitiveness Institute (ACI) at the Lee Kuan Yew School of Public Policy, National University of Singapore takes into account different factors that collectively shape the ability of a nation to achieve substantial and inclusive economic development over a sustained period of time.ACI's methodology goes beyond rankings to conduct policy simulations on how each state or federal territory can improve its competitiveness. These policy simulations are a compelling value-added proposition enabling policymakers, industry leaders and administrators to identify relative challenges and opportunities, and to prioritise areas when crafting policies and development strategies.

IN THE NEWSWeimin Wu: pioneer physicist on Chinese science's turbulent past, promising futureTimes Higher Education, 25 February 2016While the first 30 years of new China's scientific development was a self-reliant era marked by the detonations of the atomic bomb, the hydrogen bomb, and the launch of the first artificial satellite, the second 30 years after the reform and opening up was signified by the introduction of the Internet to China. Weimin Wu is a unique legendary figure whose career spanned both periods. He not only contributed to the bomb and satellite projects, but also sent out the email from China to Switzerland in 1986, which was listed as the first event in the history of China's Internet development. The Tiananmen Square Protest in 1989 changed his life's trajectory, leading him to eventually immigrate to the US. His personal emotional life is also remarkable. With his experiences immersed in both Eastern and Western cultures, Wu came to believe in the convergence theory of social development, which provides a refreshing perspective for the readers. The autobiography records the details of his legendary life stories, from taking pictures with the Chinese leader Mao Zedong, to shaking hands with Deng Xiaoping; from being removed from the Institute of High Energy Physics, to the repealing of his Chinese passport. The story line is full of engaging ups and downs. In that turbulent era, Wu's rich emotional experiences and love stories were also a mirror for the Chinese society, with some details comparable to the plots of suspense novels and movies. The book is well illustrated with many pictures and flows smoothly with a simple writing style. The stories are factual and moving, all too realistic. The author has sincerely revealed his true self to the reader, and at the same time, faithfully described that period of history, giving the reader a grasp on the true workings of history. His comparison of the Eastern and Western cultures, analysis of science and superstition, interpretation of religion and arts, and his 'convergence' theory of social development, are all unique and insightful. This book faithfully tells Weimin's professional and personal life on the cusp and takes readers on a journey to explore true history through an ordinary person's stories.
