In the current scenario of Forensic Science and Criminal Investigation, experts are facing many challenges due to huge amounts of data, tiny pieces of evidence in the chaotic and complex environment, traditional laboratory structures and sometimes insufficient knowledge which may lead to failure of investigation or miscarriage of justice. Artificial Intelligence and imaging technologies are the promising solutions to address these challenges with case based reasoning for errorless, objective and reproducible results in various fields of forensics. This book will not only provide a platform for researchers to present state of the art technologies, but will be a reference for law enforcement to use for crime investigation along with researchers in the field .

This book constructs a new theoretical framework for understanding contemporary Chinese agricultural production organizations from the perspective of promoting farmers' realization of 'substantial freedom' and 'feasible ability'. The new theoretical framework deepens and expands the theory of agricultural modernization and production organizations. The book discusses the 'multi-symbiosis' pattern of agricultural production organizations in contemporary China from macro and micro economics perspectives. Based on the peasant household economy, this multi-symbiosis organizational structure co-exists and interweaves with various forms of economic organizations. The book points out that this multi-symbiosis organizational structure is the result of free choice of the majority of farmers since the 'reform' and 'opening-up'; in turn, it also provides a broader organizational and institutional space for farmers' diversified choices. The book predicts that China's agricultural production organization networking will gradually move towards networking based on diversification and also form networked organization groups.

For centuries, Chinese medicinal materials have been used for therapeutic purposes. Chinese medicinal materials are traditionally identified by their organoleptic characteristics, such as the texture or the odor. With the advancement of DNA technology, a molecular approach has become an important tool to complement organoleptic, morphological, anatomical and chemical techniques for the authentication and quality assurance of Chinese medicinal materials.In 2002, the authors published Authentication of Chinese Medicinal Materials by DNA Technology which is the first international reference in this field. After 20 years, this new edition updates the various useful techniques and describes the new techniques developed for molecular authentication. The procedures of each DNA technique are provided in detail for 'step-by-step' experiments.This book is divided into 5 parts with 18 chapters. Part I reviews the current status of molecular authentication and introduces a wide range of DNA techniques. Part II lists the experimental procedures for molecular authentication. Part III describes the DNA fingerprinting-based techniques. Part IV describes the DNA sequencing-based techniques. Finally, Part V provides an account on the recent advancement in molecular authentication, including guidelines for setting up a proper DNA laboratory and concluding remarks.

Social and environmental factors have profound impacts on health and diseases across the lifespan. Each year, hundreds of millions of animals are used in biomedical research. Yet many experimental studies utilize animals housed in standard conditions conferring minimal physical, social, and mental stimulation. Lacking appreciation of macroenvironment impacts on physiology and disease risks of the laboratory animals may not only hinder the use of appropriate animal models for human diseases, but also question the validity of preclinical assessments of therapeutic agents.This book summarizes our work on environmental enrichment, a housing condition for laboratory animals, recapitulating an active lifestyle by providing a complex physical, social, and cognitive stimulations. Environmental enrichment exerts a wide range of benefits on energy balance, cancer, immunity, stress, behavior, and healthy aging. One underlying mechanism is the activation of a specific neuroendocrine brain-adipocyte axis with brain-derived neurotrophic factor as the key brain mediator. This book integrates recent discoveries regarding mechanisms, mediators, and biomarkers of environmental enrichment, and discusses its translational potential.By providing a timely review and discussion of murine models, this book should be of interest to basic, translational, and clinical researchers, as well as psychologists, nutrition scientists, and students that have interest in cancer, obesity, aging, and genetic disorders.

This book presents the proceedings of the 6th EAI International Conference on Robotics and Networks 2022 (ROSENET 2022).

The authors posit that big networks will be the main approach to the next generation of robotic research, with the explosive number of networks models and increasing computational power of computers significantly extending the number of potential applications for robotic technologies while also bringing new challenges to the networking community. The conference provided a platform for researchers to share up-to-date scientific achievements in this field. The conference took place December 15-16, 2022, Mangalam College of Engineering, Kottayam, Kerala, India.

This book contains some selected papers from the International Conference on Extreme Learning Machine 2019, which was held in Yangzhou, China, December 14-16, 2019. Extreme Learning Machines (ELMs) aim to enable pervasive learning and pervasive intelligence. As advocated by ELM theories, it is exciting to see the convergence of machine learning and biological learning from the long-term point of view. ELM may be one of the fundamental 'learning particles' filling the gaps between machine learning and biological learning (of which activation functions are even unknown). ELM represents a suite of (machine and biological) learning techniques in which hidden neurons need not be tuned: inherited from their ancestors or randomly generated. ELM learning theories show that effective learning algorithms can be derived based on randomly generated hidden neurons (biological neurons, artificial neurons, wavelets, Fourier series, etc) as long as they are nonlinear piecewise continuous, independent of training data and application environments. Increasingly, evidence from neuroscience suggests that similar principles apply in biological learning systems. ELM theories and algorithms argue that "random hidden neurons" capture an essential aspect of biological learning mechanisms as well as the intuitive sense that the efficiency of biological learning need not rely on computing power of neurons. ELM theories thus hint at possible reasons why the brain is more intelligent and effective than current computers. The main theme of ELM2019 is Hierarchical ELM, AI for IoT, Synergy of Machine Learning and Biological Learning. This conference provides a forum for academics, researchers and engineers to share and exchange R&D experience on both theoretical studies and practical applications of the ELM technique and brain learning. This book covers theories, algorithms and applications of ELM. It gives readers a glance of the most recent advances of ELM.

Social media and emerging internet technologies have expanded the ideas of marketing approaches.
