Two days after the terrible attack against the World Trade Center on September 11, 2001, a union construction worker made a remarkable discovery within the ruins of World Trade Center 6. He saw a cross-like beam that stood on top of a heap of debris. He was stunned by its significance as were countless others after him. The purpose of this book is to trace the thirteen-year odyssey of this iconic cross from World Trade Center 6, to its position atop a concrete abutment within the World Trade Center during the recovery and rebuilding period, to the outside wall of St. Peter’s Roman Catholic Church across from Ground Zero and finally to the National 9/11 Memorial Museum where it remains today. The odyssey also includes a three-year legal battle whose appellate decision found that the Constitution of the United States does not preclude the presence of the Ground Zero cross within the National 9/11 Memorial Museum. This book is the author’s personal memoir. He is a Franciscan priest who, through many uncertain days, was the unofficial guardian of the Ground Zero cross. The concurrent themes of the book treat spirituality, grief sharing, selfless sacrifice, architecture, church history, biblical theology, and litigation. The book tells the story of many obstacles transcended on the way to the triumph of the Ground Zero cross.

The book reports two approaches of implementation of the essential components of a Digital Phase Locked Loop based system for dealing with wireless channels showing Nakagami-m fading. It is mostly observed in mobile communication. In the first approach, the structure of a Digital phase locked loop (DPLL) based on Zero Crossing (ZC) algorithm is proposed. In a modified form, the structure of a DPLL based systems for dealing with Nakagami-m fading based on Least Square Polynomial Fitting Filter is proposed, which operates at moderate sampling frequencies. A sixth order Least Square Polynomial Fitting (LSPF) block and Roots Approximator (RA) for better phase-frequency detection has been implemented as a replacement of Phase Frequency Detector (PFD) and Loop Filter (LF) of a traditional DPLL, which has helped to attain optimum performance of DPLL. The results of simulation of the proposed DPLL with Nakagami-m fading and QPSK modulation is discussed in detail which shows that the proposed method provides better performance than existing systems of similar type.

Handbook of Sleep Research, Volume 30, provides a comprehensive review of the current status of the neuroscience of sleep research. It begins with an overview of the neural, hormonal and genetic mechanisms of sleep and wake regulation before outlining the various proposed functions of sleep and the role it plays in plasticity, and in learning and memory. Finally, the book discusses disorders of sleep and waking, covering both lifestyle factors that cause disrupted sleep and psychiatric and neurological conditions that contribute to disorders. Emphasizes a comparative and multidisciplinary approach to the topic of sleep Covers the neurobiology and physiology of sleep stages, mechanisms of waking, and dreaming Discusses in detail the proposed functions of sleep, from health and rest, to memory consolidation and synaptic plasticity Examines the current state of research in mammalian and non-mammalian species, ranging from primates to invertebrates
