This monograph is devoted to the existence and stability (Ulam-Hyers-Rassias stability and asymptotic stability) of solutions for various classes of functional differential equations or inclusions involving the Hadamard or Hilfer fractional derivative. Some equations present delay which may be finite, infinite, or state-dependent. Others are subject to impulsive effect which may be fixed or non-instantaneous.Readers will find the book self-contained and unified in presentation. It provides the necessary background material required to go further into the subject and explores the rich research literature in detail. Each chapter concludes with a section devoted to notes and bibliographical remarks and all abstract results are illustrated by examples. The tools used include many classical and modern nonlinear analysis methods such as fixed-point theorems, as well as some notions of Ulam stability, attractivity and the measure of non-compactness as well as the measure of weak noncompactness. It is useful for researchers and graduate students for research, seminars, and advanced graduate courses, in pure and applied mathematics, physics, mechanics, engineering, biology, and all other applied sciences.

This book describes the framework of a new theory of science.Over the last hundred years, philosophy of science has developed its theory based on what philosophers perceived what science is and what scientists do. It does not address the basic questions that scientists care about. Thus, this book examines the conventional theories of philosophy of science from a completely different point of view and describes the most difficult problems that scientists are concerned about and how science is conducted.This book is based on the lecture notes under the same title in Honors College at the junior level in UMASS Lowell. It is qualified as a required course in Art and Humanity for science and engineering majors.

In the existing reports on national competitiveness and rankings such as IMD World Competitiveness Yearbook and WEF Global Competitiveness Report, there are sizable discrepancies in the ranking order for the same countries. As a result, the reader is often confused because such an outcome creates difficulties for government officials when translating these findings into real-world policies. These discrepancies are actually due to the differences in logic and analytical models used by IMD and WEF. Therefore, in recognizing the problems and limitations of these models, this book presents the IPS model as a new approach. As an extension of Michael Porter's diamond model, it demonstrates a robust set of methodologies as well as offers a number of key policy implications for countries around the world that wish to enhance their national competitiveness.The analytical tools used in this book can be further utilized for other units of analysis such as industries and firms. As this book provides a series of sophisticated methodologies and specific guidelines for enhancing national competitiveness, both academics and practitioners can derive useful implications from this research. Alongside the theoretical frameworks and methodologies for national competitiveness presented in this book, timely topics are included such as the COVID-19 global pandemic and the US-China trade war. This book also includes various country-specific real-world cases that are assessed from the perspective of both developed and developing countries.

His life thrown into chaos by the death of his father in his youth, Linus Pauling persevered through an impoverished childhood to become one of the great scientists and humanitarians of the 20th century. In a stunningly original examination of the two-time Nobel Laureate, Oregon State University archivist Chris Petersen touches upon the major eras of Pauling's life and dials into specific episodes, themes, accomplishments, and failures at a level of detail that has not been put forth elsewhere. Topics exclusively covered here include Pauling's generative process as author of the groundbreaking text The Nature of the Chemical Bond; the colorful history of the Linus Pauling Institute; his symbiotic relationship with the W H Freeman & Co. publishing house; two entirely separate clashes with the United States Senate and the Soviet Academy of Science; and the story of his brilliant and troubled son Peter. Interspersed throughout the book are light pieces that narrate humorous moments in Pauling's life and other vignettes that lend insight into his seemingly maverick personality. The culmination of 15 years of research, Visions of Linus Pauling is a magisterial piece of work, equivalent to previously unseen footage of a blockbuster movie.The Pauling Blog: https: //paulingblog.wordpress.com/2022/11/03/we-wrote-a-book/

Quantum hydrodynamics comes from superfluid, superconductivity, semiconductor and so on. Quantum hydrodynamic model describes Helium II superfluid, Bose-Einstein condensation in inert gas, dissipative perturbation of Hamilton-Jacobi system, amplitude and dissipative perturbation of Eikonal quantum wave and so on. Owing to the broad application of quantum hydrodynamic equations, the study of the quantum hydrodynamic equations has aroused the concern of more and more scholars. Based on the above facts, we collected and collated the data of quantum hydrodynamic equations, and studied the concerning mathematical problems.The main contents of this book are: the derivation and mathematical models of quantum hydrodynamic equations, global existence of weak solutions to the compressible quantum hydrodynamic equations, existence of finite energy weak solutions of inviscid quantum hydrodynamic equations, non-isentropic quantum Navier-Stokes equations with cold pressure, boundary problem of compressible quantum Euler-Poisson equations, asymptotic limit to the bipolar quantum hydrodynamic equations.

It has added many new examples, problems and answers. It can be used as an undergraduate text at most universities.

What are we humans, and how did we become the high technology species? What would be our legacy? What is the ultimate meaning of life? Many of these questions are still waiting for full and complete answers and explanations.For thousands of years humans have pondered the fundamental questions about origin, existence and reality, and also about mind, consciousness, communication and social issues. In this day and age when advancing technology is quickly transforming our societies and our ways of life, these questions are more important than ever, not only in the theoretical sense, but also in practice. We have to understand what has happened, and what is happening.For the first time in the history, technology has given us powerful means to investigate the phenomena behind the ultimate questions. However, technology is only a tool; the thinking human is still required for the understanding of the world.This book explores these curious topics, beginning from the origin of the Universe to the emergence of life; the evolution from cells to brains; the development of cognitive ability from perception and attention to reasoning and thinking; how we interact with other humans by means of love and emotion; to the creation of thinking machines by weird technology.THIS BOOK presents novel views on these questions and provides explanations and possible answers in an easy-to-read style.

This book is the seventh volume of review chapters on advanced problems of phase transitions and critical phenomena, the former six volumes appeared in 2004, 2007, 2012, 2015, 2018, and 2020. The aim of the book is to provide reviews in those aspects of criticality and related subjects that are currently attracting much attention due to essential new contributions.The book consists of five chapters. They discuss criticality of complex systems, where the new, emergent properties appear via collective behaviour of simple elements as well as historical aspects of studies in the field of critical phenomena. Since all complex systems involve cooperative behaviour between many interconnected components, the field of phase transitions and critical phenomena provides a very natural conceptual and methodological framework for their study.As the first six volumes, this book is based on the review lectures that were given in Lviv (Ukraine) at the "Ising lectures" - a traditional annual workshop on complex systems, phase transitions and critical phenomena which aims to bring together experts in these fields with university students and those who are interested in the subject.

In recent years, discussion on tourism has focused mainly on global problems relating to the over-exploitation of space, leaving other aspects of the development of tourist activities almost completely ignored. The book will focus not only on the widely understood tourist exploitation processes, their geographical diversity and density, but also on their significance and influence (economic, socio-cultural, tourist etc.) on regional development and sustainability. It will also cover the debate on promotion of innovative, sustainable and responsible tourism strategies, plans and funds, and the movement towards responsible and sustainable cultural tourism through the crisis in marginal areas. It will also highlight the dramatic changes to the global tourism industry brought about by the COVID-19 pandemic in recent months.
