This book offers a systematic and rigorous treatment of continuous-time Markov decision processes, covering both theory and possible applications to queueing systems, epidemiology, finance, and other fields. Unlike most books on the subject, much attention is paid to problems with functional constraints and the realizability of strategies. Three major methods of investigations are presented, based on dynamic programming, linear programming, and reduction to discrete-time problems. Although the main focus is on models with total (discounted or undiscounted) cost criteria, models with average cost criteria and with impulsive controls are also discussed in depth. The book is self-contained. A separate chapter is devoted to Markov pure jump processes and the appendices collect the requisite background on real analysis and applied probability. All the statements in the main text are proved in detail. Researchers and graduate students in applied probability, operational research, statistics and engineering will find this monograph interesting, useful and valuable. .

Relying upon a standard New Keynesian DSGE, we propose an explanation for two empirical findings in the international finance literature. First, the unbiasedness hypothesis - the proposition that expost exchange rate depreciation matches interest differentials - is rejected much more strongly at short horizons than at long. Second, even at long horizons, the unbiasedness hypothesis tends to be rejected when one of the currencies has experienced a long period of low interest rates, such as in Japan and Switzerland. Using a calibrated New Keynesian dynamic stochastic general equilibrium model, we show how a monetary policy rule can induce the negative (positive) correlation between depreciation and interest differentials at short (long) horizons. The tendency to reject unbiasedness for Japan and Switzerland even at long horizons we attribute to the interaction of the monetary reaction function and the zero lower bound.

This Atlas provides an easy-to-follow operational guide to laparoscopic techniques. It features a wealth of photos to illustrate esophageal carcinoma surgery. Through step-by-step anatomical photographs, it clearly depicts the Ivor-Lewis operative and Ivor-Lewis-Mckeown operative techniques. Using a consistent format, it addresses the clinical anatomy, pre-operative considerations, operative steps, post-operative care, and pearls and pitfalls to make it easy-to-read. The authors emphasize the similarities of the principles and steps between open and laparoscopic surgery, which significantly simplifies the transition from one practice to the other. This Atlas also includes a description of anesthesia techniques, a guide to the use of staplers in laparoscopic surgery, and a comparison of the energy sources available for laparoscopic surgery, while also outlining future developments, e.g. the increasing prevalence of robotic surgery for these procedures. The Atlas offers an essential guide for practitioners and trainees, laparoscopic and thoracoscopic surgeons, and experienced esophageal surgeons who are preparing to change to minimal invasive techniques for the management of esophageal carcinoma. It will also benefit all surgeons who are seeking clear photos detailing how to perform these esophageal carcinoma operations.

This book aims to analyze two contrasting trends of integration and rivalry among great powers and regional states of Himalaya. It examines the interactions between the great powers and the small states in the Himalayan region, analyzes the multiple effects of the great power rivalry on the regional cooperation, and predicts the possible directions of the future of the geo-politics and geo-economy in the Himalayan region by incorporating the most recent developments. The main content of the book is divided into 11 parts. The Introduction briefly explains the aims and scope of this book. The following chapter focuses on the Buddhist ties between China and the Himalayan states in the past two millennia and its dual influence in the Himalayan region. The rest 9 chapters provide an in-depth analyses of the security dilemma between China and India, Indian perspectives on China-South Asian relations, Chinese perspectives on U.S. and Japan's engagement with South Asia and Indo-Myanmar relations, and Pakistan, Sri Lanka, Bangladesh and Nepal's responses to the regional integration and great power rivalry in the Himalayan region respectively. This is the first study which brings the Himalaya region at the center of geopolitical and geo-economics cooperation and rivalry thus highlighting its significance in Asian politics. It offers a comprehensive analysis of the complicated geo-political and geo-economic competition in the Himalayan region by inviting experts from both South Asia and China to contribute chapters. It also balances the west-centered views on the great power rivalry by introducing cultural perspective and small state perspective. The broad approach adopted in the book with focus on all important countries expands the scope of readership beyond specific academic community. The book will interest academics, policy makers, journalists, general reader and students of Asian politics.

Perception of human beings has evolved from natural biosensor to powerful sensors and sensor networks. In sensor networks, trillions of devices are interconnected and sense a broad spectrum of contexts for human beings, laying the foundation of Internet of Things (IoT). However, sensor technologies have several limitations relating to deployment cost and usability, which render them unacceptable for practical use. Consequently, the pursuit of convenience in human perception necessitates a wireless, sensorless and contactless sensing paradigm. Recent decades have witnessed rapid developments in wireless sensing technologies, in which sensors detect wireless signals (such as acoustic, light, and radio frequency) originally designed for data transmission or lighting. By analyzing the signal measurements on the receiver end, channel characteristics can be obtained to convey the sensing results. Currently, significant effort is being devoted to employing the ambient Wi-Fi, RFID, Bluetooth, ZigBee, and television signals for smart wireless sensing, eliminating the need for dedicated sensors and promoting the prospect of the Artificial Intelligence of Things (AIoT). This book provides a comprehensive and in-depth discussion of wireless sensing technologies. Specifically, with a particular focus on Wi-Fi-based sensing for understanding human behavior, it adopts a top-down approach to introduce three key topics: human detection, localization, and activity recognition. Presenting the latest advances in smart wireless sensing based on an extensive review of state-of-the-art research, it promotes the further development of this area and also contributes to interdisciplinary research.
