The main objective of this book is to extend the scope of the q-calculus based on the definition of q-derivative [Jackson (1910)] to make it applicable to dense domains. As a matter of fact, Jackson's definition of q-derivative fails to work for impulse points while this situation does not arise for impulsive equations on q-time scales as the domains consist of isolated points covering the case of consecutive points. In precise terms, we study quantum calculus on finite intervals. In the first part, we discuss the concepts of qk-derivative and qk-integral, and establish their basic properties. As applications, we study initial and boundary value problems of impulsive qk-difference equations and inclusions equipped with different kinds of boundary conditions. We also transform some classical integral inequalities and develop some new integral inequalities for convex functions in the context of qk-calculus. In the second part, we develop fractional quantum calculus in relation to a new q-shifting operator and establish some existence and uniqueness results for initial and boundary value problems of impulsive fractional q-difference equations.

This volume is a review on coherent states and some of their applications. The usefulness of the concept of coherent states is illustrated by considering specific examples from the fields of physics and mathematical physics. Particular emphasis is given to a general historical introduction, general continuous representations, generalized coherent states, classical and quantum correspondence, path integrals and canonical formalism. Applications are considered in quantum mechanics, optics, quantum chemistry, atomic physics, statistical physics, nuclear physics, particle physics and cosmology. A selection of original papers is reprinted.

Inspired by real-life events of a talented 10-year old inventor, this character-building story is packed with humour, educational elements and interesting facts. Scott Sun is a talented young boy who develops inventions to solve real-life problems. His quest for a young inventors' award brings readers on a learning journey about creativity and innovation, patience and having a positive attitude towards school work. The book also deals with an issue which every child will face at some point in time: How do I react to the success of others when they have done better than me? Unique to this book is the presence of an animated phablet, Witty Wikky, who engages readers with witty explanations. Kids are also encouraged to write to Wikky and share their views about various issues encountered by them. Wikky's unique way of engaging readers brings much delight. This is a great book for students in the primary levels.

This two-volume set combines theoretical and statistical physics ideas on convective parameterization with a wealth of information on the practical and operational use of parameterizations in weather forecast and climate models. The motivation for this approach is the assumption that future advances in the subject are most likely to arise from the application of theoretical concepts to practical problems, a feeling within the community that has led to the EU-funded COST Action investigative project. Contributors to the book are leading participants in Action, all of whom have devoted much attention over the last few years to building up a thorough knowledge of both theory and practice. Parameterization of Atmospheric Convection intends to equip theoretically oriented scientists with a firm grasp of the important practical issues, and vice versa to equip application-oriented scientists with a firm grasp of the important theoretical tools. This makes the parameterization problem accessible to a wider range of scientists than before. At the same time, by providing a solid bottom up presentation of the principles and practice of parameterization, this two-volume set is the definitive reference point for current atmospheric scientists and modellers working on such problems.

The book "Leptons and Quarks" was first published in the early 1980s, when the program of the experimental search for the intermediate bosons W and Z and Higgs boson H was formulated. The aim and scope of the present extended edition of the book, written after the experimental discovery of the Higgs boson in 2012, is to reflect the various stages of this 30+ years search. Along with the text of the first edition of "Leptons and Quarks" it contains extracts from a number of books published by World Scientific and an article from "On the concepts of vacuum and mass and the search for higgs" available from http: //www.worldscientific.com/worldscinet/mpla or from http: //arxiv.org/abs/1212.1031. The book is unique in communicating the Electroweak Theory at a basic level and in connecting the concept of Lorenz invariant mass with the concept of the Extended Standard Model, which includes gravitons as the carriers of gravitational interaction.

Over the past few decades, rapid urbanisation has threatened to erode public space, especially in emerging economies. Market forces that prioritise profit generation are allowed to construct venues of consumption in its place. Though their physical appearance may resemble traditional public space, in reality, they are greatly restrictive and diminished in affordability, accessibility and social meaning. It is in this context that William SW Lim, chairman of Asian Urban Lab, has brought together architects, designers, historians, sociologists and urbanists from the region to discuss public space in selected Asian cities. Part One contains essays from participants from Chongqing, Hong Kong, Jakarta, Kuala Lumpur, Singapore and Taipei and observations from commentators. Several essays by William SW Lim on the subject round off the discussion in Part Two. The thoughtful essays in Public Space in Urban Asia emphasise how engaging with the present actuality of cities and public awareness of spatial justice in cities are crucial for it is the achievement of spatial justice that will help create a greater level of happiness across societies in our increasingly urbanised world.

This book provides a selection of papers of the late Daniel Amit (1938 2007). Daniel Amit was a physicist who spent the last 22 years of his life working on neural network models. He was one of the pioneers in the field. The volume contains 21 papers, from the highly influential 1985 paper on the Hopfield model (published together with Hanoch Gutfreund and Haim Sompolinsky), to his last (unpublished) manuscript. Many of these papers are landmark papers in the field. The book also provides a biography; an introduction on Daniel Amit's scientific career before the Hopfield model; and introductions to each of the included papers, written by their co-authors. This book will be of interest to physicists, computational neuroscientists and neurobiologists.

Over the six-month period from late 2012 to early 2013, Hu Jintao, the President of the People's Republic of China, Chair of the Central Military Commission, and Party Secretary of the Chinese Communist Party (CCP), will relinquish at least two of his three positions. According to the constitution of the CCP, his time as Party head will come to an end, given that he has already served for two terms. Well over the supposed retirement age of 68, he will have to hand over the leadership of China to a new generation of leaders at the 18th Party Congress in Beijing. In Chinese politics, the act of retirement is surprisingly difficult, but Hu Jintao is widely known for his reserve and reticence; there is little doubt that he could disappear into a quiet and anonymous retirement if he so desires. This timely volume thus aims to provide an analytical assessment of Hu's period in charge of the world's most populous country. It concentrates briefly on his early life and entry into politics, then considers and evaluates his stewardship of the economy and of international affairs, as well as his ideological contribution and leadership of the communist party. In the process, the reader will also be afforded a broad overview of China's rapid developments over the last decade, since 2002.

The book describes in a simple and practical way what non-equilibrium thermodynamics is and how it can add to engineering fields. It explains how to describe proper equations of transport, more precise than used so far, and how to use them to understand the waste of energy resources in central unit processes in the industry. It introduces the entropy balance as an additional equation to use, to create consistent thermodynamic models, and a systematic method for minimizing energy losses that are connected with transport of heat, mass, charge, momentum and chemical reactions.

The current book attempts to give a glimpse of the scientific life of Michael Rossmann. The book begins with his very interesting and moving autobiography. His enormous energy must have been evident already from early childhood when he and his mother had to emigrate from Nazi-Germany to England, via The Netherlands. Starting school with a new language was a challenge that he managed well with the assistance of understanding teachers. Crystallography soon became the tool to explore new worlds, unknown to everybody. With a skill for mathematics, he realized that the transform of a molecular structure in the diffraction pattern could be used for analysis of both symmetry and structural relationships. This method, molecular replacement (MR, also the initials of his name) became one of his great successes of his career. The previous book by him in this series (Selected Papers by Michael G Rossmann with Commentaries) covers his main contributions in this area. With an interest in symmetry, viruses became obvious objects to study. Rossmann attacked these monstrously large molecular assemblies with his unfailing energy and his appetite for real challenges. The amazing variation of molecular arrangements with icosahedral symmetry is truly amazing. This book includes a selection of reports of the structures of some giant viruses. As always, knowing the structure enhances the understanding of function greatly, in the case of viruses the mechanism of infection is a key problem. Rossmann has contributed many central insights in this area. Thus, this book is of interest both as an interesting personal story but also for research into viruses that repeatedly plague all living organisms on the planet, right now in the form of the corona virus pandemic.

Werner Heisenberg and Richard Feynman find quantum physics fascinating and necessary for understanding the atoms. Albert Einstein dislikes it and Isaac Newton does not understand it, which is not surprising. This is the scenario for animated discussions between five people. Harald Fritzsch brings together Newton and the three great physicists of the 20th century in an imaginary meeting. His "alter ego" Adrian Haller moderates the discussions. By means of questions and answers the whole cosmos of quantum physics is described in a simple way, easily understandable non-physicists. The beginnings of quantum theory and atomic physics as well as the importance of quantum physics for our daily life these and many more topics are the subjects of the interesting and fascinating discussions.

There is a lack of knowledge on how corporations in Asia develop strategies, organize their work processes and deal with competition. Western managers and business students need to know more about Asian corporations and their management styles. Learning about Asia, however, has always been a challenging task. The main challenge is the complexity encountered when dealing with Asian management issues, which differ not only for different countries, but also for different types of businesses, not to mention national management preferences and styles. This book tries to fill this gap, by presenting case studies of various Asian countries including China, Japan, India, Korea and The Philippines. The case studies are as diverse as management activities in Asia can be and include a variety of different companies in several Asian countries. This book attempts to present an overview on the variety and complexity of management and business processes in Asian countries. It intends to support business people and students of international management to get a deeper understanding of Asian management practices by presenting practical examples of Asian firms and their strategies.

Prudence, Pragmatism and Principle examines New Zealand's approach to national security by taking the country's own definition of security and examining each of the components within that definition to determine what the country has or has not done to achieve security.The book highlights the centralised all-of-government approach to achieving security policy and its more distributed and focused approach to responding to national security issues. It also evaluates the degree to which the country chooses to follow a path of prudence, pragmatism or principle in achieving its security. The emphasis on each of those is different according to the issue.The author first presents the development of New Zealand's thinking about security issues and the structure of the national security system. He then delves into case studies of security concern including the national demand for security, international disorder, New Zealand's immediate region and its security, disruptions in the domestic sphere, and natural hazards as a security issue. The final substantive chapter examines how New Zealand works to achieve its security goal of the freedom of citizens 'to make the most of opportunities to advance their way of life'; an unusual national security goal and one that is difficult to achieve or even to define.

Voronoi diagrams partition space according to the influence certain sites exert on their environment. Since the 17th century, such structures play an important role in many areas like Astronomy, Physics, Chemistry, Biology, Ecology, Economics, Mathematics and Computer Science. They help to describe zones of political influence, to determine the hospital nearest to an accident site, to compute collision-free paths for mobile robots, to reconstruct curves and surfaces from sample points, to refine triangular meshes, and to design location strategies for competing markets. This unique book offers a state-of-the-art view of Voronoi diagrams and their structure, and it provides efficient algorithms towards their computation. Readers with an entry-level background in algorithms can enjoy a guided tour of gently increasing difficulty through a fascinating area. Lecturers might find this volume a welcome source for their courses on computational geometry. Experts are offered a broader view, including many alternative solutions, and up-to-date references to the existing literature; they might benefit in their own research or application development.

Globalisation has become a rewarding but challenging fact of life for scientific and scholarly researchers. Intellectually, they work with shared understandings of their areas of research and research methods. Professionally, responsibility and best practices are subject to many different rules and standards that vary across disciplines, countries, and cultures. They know how to measure and study the objects of their research but are often less sure of what constitutes the responsible practice of research or research integrity. The World Conferences on Research Integrity provide a forum for an international group of researchers, research administrators from funding agencies and similar bodies, research organisations performing research, universities and policy makers to discuss and make recommendations on ways to improve, harmonise, publicise, and make operationally effective international policies for the responsible conduct of research. The second such conference, held in Singapore in July 2010, focused on challenges and responses. Where is integrity in research today most significantly challenged and what is being done to address these challenges? This volume brings together a selection of presentations and key guidelines and statements emerging from the Conference.

The main goal of the book is to provide a comprehensive and self-contained proof of the, relatively recent, theorem of characterization of the strong maximum principle due to Molina-Meyer and the author, published in Diff. Int. Eqns. in 1994, which was later refined by Amann and the author in a paper published in J. of Diff. Eqns. in 1998. Besides this characterization has been shown to be a pivotal result for the development of the modern theory of spatially heterogeneous nonlinear elliptic and parabolic problems; it has allowed us to update the classical theory on the maximum and minimum principles by providing with some extremely sharp refinements of the classical results of Hopf and Protter-Weinberger. By a celebrated result of Berestycki, Nirenberg and Varadhan, Comm. Pure Appl. Maths. in 1994, the characterization theorem is partially true under no regularity constraints on the support domain for Dirichlet boundary conditions. Instead of encyclopedic generality, this book pays special attention to completeness, clarity and transparency of its exposition so that it can be taught even at an advanced undergraduate level. Adopting this perspective, it is a textbook; however, it is simultaneously a research monograph about the maximum principle, as it brings together for the first time in the form of a book, the most paradigmatic classical results together with a series of recent fundamental results scattered in a number of independent papers by the author of this book and his collaborators. Chapters 3, 4, and 5 can be delivered as a classical undergraduate, or graduate, course in Hilbert space techniques for linear second order elliptic operators, and Chaps. 1 and 2 complete the classical results on the minimum principle covered by the paradigmatic textbook of Protter and Weinberger by incorporating some recent classification theorems of supersolutions by Walter, 1989, and the author, 2003. Consequently, these five chapters can be taught at an undergraduate, or graduate, level. Chapters 6 and 7 study the celebrated theorem of Krein Rutman and infer from it the characterizations of the strong maximum principle of Molina-Meyer and Amann, in collaboration with the author, which have been incorporated to a textbook by the first time here, as well as the results of Chaps. 8 and 9, polishing some recent joint work of Cano-Casanova with the author. Consequently, the second half of the book consists of a more specialized monograph on the maximum principle and the underlying principal eigenvalues.

This book provides a broad introduction into the field of particle physics for the general reader through virtual discussions among prominent physicists, Albert Einstein, Murray Gell-Mann, Issac Newton and a modern physicists. Matter is composed of quarks and electrons. The electrons interact with the atomic nuclei by the exchange of photons. The forces between the quarks are generated by the exchange of gluons, which leads to the confinement of the quarks. The weak bosons provide the weak forces among the leptons and quarks. The book is suitable for non-experts in physics.

Quantum computing - the application of quantum mechanics to information represents a fundamental break from classical information and promises to dramatically increase a computer's power. Many difficult problems, such as the factorization of large numbers, have so far resisted attack by classical computers yet are easily solved with quantum computers. If they become feasible, quantum computers will end standard practices such as RSA encryption. Most of the books or papers on quantum computing require (or assume) prior knowledge of certain areas such as linear algebra or quantum mechanics. The majority of the currently-available literature is hard to understand for the average computer enthusiast or interested layman. This text attempts to teach quantum computing from the ground up in an easily readable way, providing a comprehensive tutorial that includes all the necessary mathematics, computer science and physics.

In 1980, the Cold War was in full bloom. The Soviet father of the hydrogen bomb and Nobel Peace Laureate turned dissident physicist, Andrei Sakharov, had been exiled to Gorki by the Soviet authorities. Called "senile" and under heavy Soviet censorship, Sakharov had a hard time communicating his latest scientific results to readers outside of Gorki. Some smuggled results reached the author, Harry Lipkin, who then realized that he and Sakharov were both pioneers in a new revolution on our understanding the structure of matter. The particle physics community had resisted their revelation that the accepted building blocks of matter, neutrons and protons, were composed of tinier building blocks called "quarks." What followed was a remarkable adventure in which both scientists fought the Soviet censors, smuggling postcards and manuscripts into and out of the Soviet Union while trying to further scientific progress. Against a backdrop of politics, suppression, and genius, Andrei Sakharov, Quarks and the Structure of Matter details the search for the basic building blocks of matter, the path to understanding the forces that bind them together, and how scientific knowledge is learned, communicated and passed from one group of investigators to another.
