Sommario/riassunto |
|
PWM DC-DC power converter technology underpins many energy conversion systems including renewable energy circuits, active power factor correctors, battery chargers, portable devices and LED drivers. Following the success of Pulse-Width Modulated DC-DC Power Converters this second edition has been thoroughly revised and expanded to cover the latest challenges and advances in the field. Key features of 2nd edition: Four new chapters, detailing the latest advances in power conversion, focus on: small-signal model and dynamic characteristics of the buck converter in continuous conduction |

Sommario/riassunto |
|
This book reviews all important aspects of anxiety disorders with the aim of shedding new light on these disorders through combined understanding of traditional and novel paradigms. The book is divided into five sections, the first of which reinterprets anxiety from a network science perspective, examining the altered topological properties of brain networks in anxiety disorders. The second section discusses recent advances in understanding of the neurobiology of anxiety disorders, covering, for example, gene-environmental interactions and the roles of neurotransmitter systems and the oxytocin system. A wide range of diagnostic and clinical issues in anxiety disorders are then addressed, before turning attention to contemporary treatment approaches in the context of novel bio-psychosocial-behavioral models, including bio- and neurofeedback, cognitive behavioral therapy, neurostimulation, virtual reality exposure therapy, pharmacological interventions, psychodynamic therapy, and CAM options. The final section is devoted to precision psychiatry in anxiety disorders, an increasingly important area as we move toward personalized treatment. Anxiety Disorders will be of interest for all researchers and clinicians in the field. |
