After planting a seed, the blue bird returns to find a full-grown tree, admiring how it changes through every season of the year. At first, she is delighted by its bright flowers and beautiful green leaves, but as winter approaches, the leaves fall, leaving the little tree barren and cold. The little tree worries that the blue bird won't love it anymore now that its colorful flowers are gone. However, the blue bird continues to care for the tree through every change, so much so that she makes her home within its branches-keeping the tree company for the rest of their lives. A Blue Bird and Her Little Tree is a story of love that lasts through hard times and all of life's ups and downs. The blue bird and her tree learn about loyalty and growth through whatever changes might come.

This book provides a snapshot of the COVID-19 pandemic situation from the perspective of the tourism, aviation and hospitality industries. The book analyzes the challenges and possible strategies for recovery to meet the urgent needs of the industry to deal with this catastrophic health crisis. A good part of the book discusses the negative effect of the pandemic to these industrial sectors and the strategies to reduce it. The book also explores other aspects of the tourism and hospitality development as the base for recovery such as applying more flexible business models, understanding the resident’s perception and emotion experience, strengthening the human resource management, and improving the destination image for marketing, etc. Some long-term issues are also discussed such as management education and environment protection education. The book is highly recommended for tourism and aviation researchers, policy makers, industry practitioners, and graduate students. This book is a collection of selected papers from the 10th International Conference on Tourism and Hospitality between China and Spain (www.china-spain.org).

This book constitutes the thoroughly refereed post-conference proceedings of the 14th International Conference on Mobile Multimedia Communications, Mobimedia 2021, held in July 2021. Due to COVID-19 pandemic the conference was held virtually. The 66 revised full papers presented were carefully selected from 166 submissions. The papers are organized in topical sections as follows: Internet of Things and Wireless Communications Communication; Strategy Optimization and Task Scheduling Oral Presentations; Privacy Computing Technology; Cyberspace Security and Access control; Neural Networks and Feature Learning Task Classification and Prediction; Object Recognition and Detection.

This book analyzes a broad variety of tourism products in China, Asia and Europe that employ both cutting-edge IT technologies and advanced methodologies. These products are cultural tourism, recreational tourism, sport tourism, adventure tourism, medical tourism and more. Authors from different areas contributed to the book, including academic researchers, graduate students, government administrators and industry practitioners. The book covers the entire chain of tourism product business processes: product development and improvement, tourist behavior analysis, marketing and sales, customer service, etc. In addition, it addresses related issues such as tourism sustainability, policymaking, environmental protection and human resource development. Big data processing, data mining, visual content analysis and textural content analysis, semantic nets and sentiment analysis are among the cutting-edge technological tools used to study tourism product development here. The book gathers selected papers from the 9th International Conference on Tourism and Hospitality between China and Spain (www.china-spain.org) with participants from 18 countries. Though the book is mainly intended for researchers and policymakers, it will also appeal to a wider audience, due to its first-hand content, insightful analysis and broad geographic coverage.

This work covers sequence-based protein homology detection, a fundamental and challenging bioinformatics problem with a variety of real-world applications. The text first surveys a few popular homology detection methods, such as Position-Specific Scoring Matrix (PSSM) and Hidden Markov Model (HMM) based methods, and then describes a novel Markov Random Fields (MRF) based method developed by the authors. MRF-based methods are much more sensitive than HMM- and PSSM-based methods for remote homolog detection and fold recognition, as MRFs can model long-range residue-residue interaction. The text also describes the installation, usage and result interpretation of programs implementing the MRF-based method.

Metal oxides and particularly their nanostructures have emerged as animportant class of materials with a rich spectrum of properties and greatpotential for device applications. In this book, contributions from leadingexperts emphasize basic physical properties, synthesis and processing, and thelatest applications in such areas as energy, catalysis and data storage. Functional Metal Oxide Nanostructuresis an essential reference for any materials scientist or engineer with aninterest in metal oxides, and particularly in recent progress in defectphysics, strain effects, solution-based synthesis, ionic conduction, and theirapplications.

Science and engineering disciplines are provoking fundamental and applied discoveries in numerous applications, such as to deeply understand brain functions, precisely diagnose diseases, and to then properly address these. The later advances call upon biomedical integrated circuits and systems (BioCAS) to provide needed research tools. In fact, with the increase of the personalized healthcare market and BioCAS featuring wearability, implantability and intelligence, it has become significantly more important to address these emerging trends. These circuits and systems deal with various signals and images such as electrophysiological, electrochemical, optical, and magnetic, which require various front-end circuits to acquire signals and usually cancel out the noise. With the booming artificial intelligence methods, these biosignals became mandatory for the monitoring, detection, diagnosis and even prediction of diseases for example.This monograph focusses on the current research activities and emerging trends that relate to the above-mentioned functionalities, and it should be of interest to students, researchers and engineers active in the fields related to Circuits and Systems for Biomedical Engineering. Section I is a summary of the main BioCAS research interests, and in Section II various biosignal acquisition circuits techniques are discussed. In Section III the authors cover circuits for biosignal processing, with emphasis on the newly emerging artificial intelligence. Sections IV and V contain a review of wireless power harvesting and communication circuits. Sections VI and VII represent circuits that help miniaturizing biomedical imaging systems, and other systems intended for the detection of chemical and molecular assays. Section VIII describes one of the main neural prostheses intended to address vision disorders, whilst the last section reviews electrode-tissue interfaces that essentially bridge the circuits and systems with the human body.
