This invaluable book provides a comprehensive treatment of the design and application of Mode Locked Lasers and Short Pulse Generation. With the advances in semiconductor laser and fiber laser technologies in the 1980s to now, these devices have been made compact, refined, and developed for a wide range of applications including further scientific studies.Semiconductor mode-locked lasers are stable pulse sources and can be made over a range of wavelengths where laser operation is feasible. Rare earth doped fiber lasers or planar waveguides extend this range further and can provide compact pulsed sources. The principles of operation, analysis, design and fabrication of these sources are described. Recent results on high repetition rate and high-power pulse generation from these compacts sources are also described, together with current and future directions of application of these types of laser sources.Mode-Locked Lasers: Introduction to Ultrafast Semiconductor and Fiber Lasers is self-contained and unified in presentation. It can be used as an advanced text by graduate students and by practicing engineers. It is also suitable for non-experts who wish to have an overview of mode-locked lasers and pulse generation. The explanations in the book are detailed enough to capture the interest of the curious reader and complete enough to provide the necessary background to explore the subject further.

This is the fourth volume of edited books constituting an eclectic collection of papers in behavioral finance based on contributions by participants of Israel Behavior Finance conferences. Like its predecessors, this book continues to be edited by Professor Itzhak Venezia (this book with Dr Rachel Calipha), who carefully selected the papers to be included in this volume.Behavioral finance has evolved significantly since its inception, and chapters in this collection reflect the diverse and dynamic nature of this field. They not only build upon the foundational concepts established in the earlier volumes but also explore novel financial products, themes, and ideas that have gained rapid prominence in recent years: From the integration of artificial intelligence into investment decision-making processes, to the analysis of the alternative meats industry, and various other alternative investment instruments such as NFTs (Non-Fungible Tokens). This collection, therefore, pushes the boundaries of what is conventionally associated with behavioral finance.

This is the first book on the problems of mathematical modeling that combines a generalized approach to the problem of mathematical modeling processes and phenomena in the real world with developing modeling methods in relation to specific objects and processes. Some of the problems discussed here include stability and bifurcation of simplified models of supply and demand, and resultants of various approaches, such as standardization, unification and partial order, data packaging.As well as touching upon the general principles of modeling, the book studies the stability of mathematical models using the generalized direct Lyapunov method based on matrix-valued auxiliary functions. It has significant potential for application in the design of new moving objects (nano-robots, manipulators, drones, etc.) and processes related to artificial intelligence (multidimensional interaction of related data arrays) that can be described by differential equations of different types.Written by two well-known specialists in the field of qualitative theory of equations and problems of modeling real-world phenomena, this book is primarily targeted at specialists in the field of engineering sciences, but is also suitable for graduate courses.

The fine balance in reactive species (RS) levels inside the cell, or redox homeostasis, is crucial for normal life. RS are molecules such as hydroxyl, superoxide, and others whose reaction rates are typically high. Further, RS are now accepted as the molecular mediators of stresses on cells. RS are also implicated in many diseases including cancer, cardiovascular diseases, and neurodegenerative diseases.In contrast to the popular view that RS are deleterious, this book discusses desirable outcomes from the manipulation of reactive species levels in the cells. The discoveries include a fundamental approach to overcome major limitations with traditional oxygen supply to bioreactors, a mere treatment of the inoculum to significantly (sometimes many-fold) increase productivity of bio-oil, enzymes, and other products from bioprocesses, unexpected effect of shear on cultivated cells, rhythms in intracellular reactive species levels and resetting the rhythm to significantly improve cancer drug efficiency.The book concludes with a description of a scalable reactive species module - one that can be integrated with any genome scale model to gain significant insights into the RS effects on metabolism.

The primary focus of the book is to explore the asymptotic behavior of problems formulated within cylindrical structures. Various physical applications are discussed, with certain topics such as fluid flows in channels being particularly noteworthy. Additionally, the book delves into the relevance of elasticity in the context of cylindrical bodies.In specific scenarios where the size of the cylinder becomes exceptionally large, the material's behavior is determined solely by its cross-section. The investigation centers around understanding these particular properties.Since the publication of the first edition, several significant advancements have been made, adding depth and interest to the content. Consequently, new sections have been incorporated into the existing edition, complemented by a comprehensive list of references.

Federated Learning is currently an emerging technology in the field of machine learning. Federated Learning is a structure which trains a centralized model for a given assignment, where the data is de-centralized across different edge devices or servers. This enables preservation of the confidentiality of data on various edge devices, as only the updated outcomes of the models are shared with the centralized model. This means the data can remain on each edge device, while we can still train a model using that data.Federated Learning has greatly increased the potential to transmute data in the healthcare industry, enabling healthcare professionals to improve treatment of patients.This book comprises chapters on applying Federated models in the field of healthcare industry.Federated Learning mainly concentrates on securing the privacy of data by training local data in a shared global model without putting the training data in a centralized location. The importance of federated learning lies in its innumerable uses in health care that ranges from maintaining the privacy of raw data of the patients, discover clinically alike patients, forecasting hospitalization due to cardiac events impermanence and probable solutions to the same. The goal of this edited book is to provide a reference guide to the theme.

This unique compendium approaches the relatively new Isogeometric Analysis (IGA) methods at senior undergraduates level in engineering or applied mathematics. It describes the differences between the well-established Finite Element Analysis (FEA) methods and why they are being replaced, or enhanced, by the latest developments in IGA.The book begins with summaries of the concepts of B-splines, NURBS, and 'knot vectors' which define them as exact representations of the geometry and as powerful analysis functions having higher continuity than the FEA use of Lagrange polynomials.The useful reference text includes Appendices with Matlab scripts for creating B-spline basis functions, topics in computer aided geometric design (CAGD) from which IGA arose, and matrix operations common to IGA and FEA. It also informs FEA users of the enhancements offered by IGA.

This book is a sequel of The Physics of Quantum Well Infrared Photodetectors (1997), which covered the basic physics of QWIPs. In the intervening 27 years, QWIP properties pertinent to infrared detection are much better understood, and QWIP technology has become a mainstream, widely deployed infrared technology. The main progress is the ability to know the QWIP absorption quantum efficiency quantitatively through rigorous electromagnetic modeling. The lack of theoretical prediction has impeded QWIP development for a long time. Generally, an arbitrary choice of detector structures yields substantial variations of absorption properties, and QWIP was regarded as a low quantum efficiency detector. With the advent of electromagnetic modeling, quantum efficiency of any detector geometry can be known exactly and be optimized to attain a large satisfactory value. Consequently, all properties of QWIPs are predictable, not unlike prevailing silicon devices. This unique characteristic enables QWIP to be the most manufacturable long wavelength infrared technology in mass production. This book by K K Choi, a co-inventor of QWIPs, will capture this exciting development.Based on the materials expounded in the book, the reader will know key performance metrics in infrared detection, in-depth knowledge of QWIP material and structural designs, array production, its application, and practical knowledge of electromagnetic modeling. In addition, the book will describe using micro- and nano-structures to enhance the emission properties of active and passive optical emitters, similar to detectors. The application of rigorous electromagnetic modeling to optical emitters is new to the optoelectronic community. The resonator-pixel emitter structure with its modeling method will no doubt be able to attract substantial academic and industrial attention in years to come.

This book serves as an introductory volume to Yair Aharoni's remarkable impact on international business (IB) research. Most IB researchers will be familiar with at least one aspect of his work, but relatively few will be familiar with his broader body of work, as it spans so many of the issues addressed today in IB and strategy. This book aims to introduce readers to the depth and breadth of his impact.Unquestionably a founder of the IB field, over the course of his long career, Aharoni influenced its earliest development and, driven by a deep connection to policy and managerial practice, continually challenged conventional thinking on IB and strategy. He generated seminal insights into many aspects of why and how firms internationalize, including managerial decision-making processes, the strategies employed by state-owned enterprises, the interaction between firms and governments, and the foreign expansion of firms - including small- and medium-sized enterprises (SMEs) and those operating in the service sector - based in small and open economies. His research contributed to several salient research directions, including the behavioral theory of the firm, emerging-market multinationals, international entrepreneurship, the service economy, and non-market strategies.Aharoni was also an influential educator, having served as the founding dean of two top business schools in Israel. He was deeply engaged with the Israeli business environment - particularly senior executives of start-up companies - and a highly-valued advisor to the Israeli government. In honor of these contributions, Aharoni was the first management scholar in Israel, to be awarded the prestigious Israel Prize in 2010. Few scholars have had such meaningful impact on research, practice, and policy.

Over the past few decades, the field of machine learning has made remarkable strides, surpassing human performance in tasks like voice and object recognition, as well as mastering various complex games. Despite these accomplishments, a critical challenge remains: the absence of general intelligence. Achieving artificial general intelligence (AGI) requires the development of learning agents that can continually adapt and learn throughout their existence, a concept known as lifelong learning.In contrast to machines, humans possess an extraordinary capacity for continuous learning throughout their lives. Drawing inspiration from human learning, there is immense potential to enable artificial learning agents to learn and adapt continuously. Recent advancements in continual learning research have opened up new avenues to pursue this objective.This book is a comprehensive compilation of diverse methods for continual learning, crafted by leading researchers in the field, along with their practical applications. These methods encompass various approaches, such as adapting existing paradigms like zero-shot learning and Bayesian learning, leveraging the flexibility of network architectures, and employing replay mechanisms to enable learning from streaming data without catastrophic forgetting of previously acquired knowledge.This book is tailored for researchers, practitioners, and PhD scholars working in the realm of Artificial Intelligence (AI). It particularly targets those envisioning the implementation of AI solutions in dynamic environments where data continually shifts, leading to challenges in maintaining model performance for streaming data.

The dynamic mechanism of plate tectonics remains a reasonable theory, but one with shortcomings such as insufficient bases for plate division, unclear plate boundaries, and unclear geological characteristics. This book proposes that the world's continents should not be divided by plates, and that their formation is not due to plate tectonics but rather due to global crustal uplift evolution and sea-land evolution. This proposal is based on the authors' broad theoretical foundation and comprehensive professional knowledge, built up over more than ten years of in-depth research by many scholars on the evolution of the Earth's continents.In this book, many case studies are better explained by global crustal uplift and sea-land evolution. Namely, that the entire continents of the world are indivisible, and the changes of each land block over geological periods resulted from the sea-land changes.The book further develops the original "geomechanics theory" created by the famous geologist Li Siguang. As a vibrant and highly rigorous work, Prof Li's book offered important theoretical guidance that enriched the global geological community and led to a re-development within geological science. The strong response highlights the significance of geomechanics theory and our theories that build upon it in this book.
