Human microbiome : Clinical implications and therapeutic interventions
The human microbiome refers to the complete microorganisms inhabiting the human body sites including skin, ear, nose, oral cavity, the genital, gastrointestinal and respiratory tracts, and body fluids such as breast milk, saliva, and urine. It is a significant and essential organ recognized for the body and has an established involvement in the host wellbeing, in terms of nutritional requirements and immunomodulation. Talks about how alteration and imbalance in the same can have clinical implications associated with a multitude of gastrointestinal, lifestyle-associated, and neurodegenerative disorders. How the proliferation of specific groups of bacteria and their metabolic activities, as a result of intestinal dysbiosis leads to the 'leaky gut' condition thereby influences brain activity via the bidirectional gut-brain axis. It also coves the importance of microbial seeding and how it can be influenced by the mode of delivery, nutrition, and medication. This book also provides various therapeutic interventions such as the establishment of stool banks and Faecal microbiota transplantation (FMT) that have recently proved promising in the treatment of ASD, Inflammatory Bowel Disease, and Ulcerative Colitis. This book provides a deeper understanding of the development of the human gut microbiome and the factors driving its dysbiosis. This book is a valuable read for health professionals, medical students, nutritionists, and scientific research communities who are eager to update themselves with recent trends in microbiome research. It will also aid gastroenterologists and nutritionists to make well-informed choices regarding therapeutic regimes.
High-Resolution If-To-Baseband ΣΔ Adc For Car Radios
High-Resolution IF-to-Baseband SigmaDelta ADC for Car Radios addresses the theory, system level design and circuit implementation of a high-resolution continuous-time IF-to-baseband quadrature SigmaDelta ADC. The target application of this ADC is in AM/FM/IBOC car radios. The ADC achieves a dynamic range of 118dB, which eliminates the need for an IF VGA or AM channel filter in car radios.
Hearing : From Sensory Processing to Perception

Fundamentals of electrical drives
This brings us to the purpose of this book namely to help students and engineers appreciate and understand the fundamental concepts of modern electrical drives. An interactive learning approach is taken in this text: theory and calculations are augmented by generic models which are transposed to a simulation platform. The 'build and play' method used in this text visualizes the dynamic operation of a comprehensive set of modules ranging from an inductance to a novel 'ideal rotating transformer' (IRTF). This module is at the center of the generic models used in this text to explore the dynamic and steady state operation of grid and converter fed induction, synchronous and DC machines. The section on modulation and control emphasizes the role of power electronics and digital signal processors in drives. Downloadable files that accompany this text have an extensive set of 'build and play' tutorials, in Simulink R° and Caspoc. The latter is a simulation platform which allows direct access to the 'build and play' modules, without further licensing needs. All figures in this text are included in the downloadable files in order to help with the preparation of customized Power Point type lecture material.
Feedforward Amplifiers for Wideband Communication Systems
Feedforward Amplifiers for Wideband Communication Systems has been possible thanks to the research carried out throughout several years in the field of the linearization techniques applied to digital communication systems, particularly to those with high spectral efficient modulation techniques. This challenge is enshrined in one of the present wideband communication systems, but all the recommended design guidelines are perfectly reusable in the future wideband applications.
Fasting and Immunity
Ramadan is the ninth month of the Islamic lunar calendar and is observed by Muslims as a month of fasting. All Muslim adults are expected to fast; nevertheless, certain subgroups, including sick, frail subjects, and pregnant women, among others, are exempted. Ramadan fasting has been shown to impact on body systems in different manners. The influence of Ramadan fasting on immune system regulation remains elusive; however, immune system changes, such as the modulation of body response to various infectious, stressful, and other harmful events, are of great interest during fasting.

Drug discovery and GBCR – Related CNS Disorders
Neurodegenerative diseases are a large group of neurological disorders with diverse etiological and pathological phenomena. However, current therapeutics rely mostly on symptomatic relief while failing to target the underlying disease pathobiology. G-protein-coupled receptors (GPCRs) are one of the most frequently targeted receptors for developing novel therapeutics for central nervous system (CNS) disorders. Many currently available antipsychotic therapeutics also act as either antagonists or agonists of different GPCRs. Therefore, GPCR-based drug development is spreading widely to regulate neurodegeneration and associated cognitive deficits through the modulation of canonical and noncanonical signals.

Digital Communications Using Chaos and Nonlinear Dynamics
This book introduces readers to a new and exciting cross-disciplinary field of digital communications with chaos. This field was born around 15 years ago, when it was first demonstrated that nonlinear systems which produce complex non-periodic noise-like chaotic signals, can be synchronized and modulated to carry useful information. Thus, chaotic signals can be used instead of pseudo-random digital sequences for spread-spectrum and private communication applications. This deceptively simple idea spun hundreds of research papers, and many novel communication schemes based on chaotic signals have been proposed. However, only very recently researchers have begun to make a transition from academic studies toward practical implementation issues, and many "promising" schemes had to be discarded or re-formulated. This book describes the state of the art (both theoretical and experimental) of this novel field.

Design and Optimization of Passive UHF RFID Systems
Radio Frequency Identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. An RFID tag is an object that can be attached to or incorporated into a product, animal, or person for the purpose of identification using radio waves. Chip-based RFID tags contain silicon chips and antennas. Active tags require an internal power source, while passive tags do not.

Cosmeceuticals as Game Changers in the Cosmetic Industry
Objectives of this work is to compare conventional cosmetics to biotechnology derived cosmeceuticals in terms of skin anti-aging, skin color modulation and hair growth, and to find out which is of greater overall performance. Research revealed superiority of cosmeceuticals to classical cosmetics as it was found that many classical cosmetic agents used for aesthetical purposes posed a certain level of either ineffectiveness, for the reason that the effect did not treat the cause of the problem and was merely temporary and external, or harmfulness because of proposed potential health risks and adverse effects. Whereas cosmeceuticals presented promising novel mechanisms and compounds for a deeper, more thorough remedy.
Corticofugal Modulation of Sensory Information
Sensory signals reach the cerebral cortex after having made synapses in different relay stations along the sensory pathway. The flow of sensory information in subcortical relay stations is controlled by the action of precise topographic connections from the neocortex. Several lines of research indicate that the massive corticifugal system improves ongoing subcortical sensory processing and reorganizes the receptive fields in visual, auditory and somatosensory systems. In all these sensory systems cortical neurons mediate both the highly focused positive feedback to subcortical neurons with ove
