The semiconductor industry has been following Moore s law over the past five decades due to the continuous CMOS process technology scaling. This scaling has led to reduced integrated circuit cost, higher integration density and better design performance. On the other hand, many new design challenges have been introduced due to scaling, and these chanllenges become more significant when migrating from one technology node to a newer one with smaller feature size. This book presents seven newly developped circuit and interconnect design methods for nanometer CMOS VLSI designs. The first four methods target issues in global on-chip signaling, on-chip busses, and clock signal distribution. Chapters six and seven of this book present circuit techniques for low-power high- speed digital circuits and high fan-in logic design. The last method presented in this book deals with the mode transition latency and energy overheads in the power-gated low-power designs.
This book discusses about current mode signaling which minimizes the delay of global interconnect with respect to voltage mode (repeater insertion technique). Current mode signaling circuits uses dynamic overdrive (strong drive while transition) principle to minimize static power dissipation. Single ended current mode signaling shows the improvement over voltage mode (repeater insertion technique) in terms of delay and power. For transmitting and receiving from both the sides bidirectional current mode signaling is discussed and it has good benefits over voltage mode signaling (repeater insertion technique).New technique of Differential current mode signaling is described in this book.
This book describes the doctoral thesis where we explore the mechanical properties of living cells using the Atomic Force Microscope (AFM). The cell membrane contains lipids microdomains, called rafts, enriched in cholesterol and sphingolipids. The lipid rafts are believed to play an important role in signal processing by acting as a signaling platform . The mechanical properties of these rafts were characterized by targeting one of its component, the GPI-anchored protein. This work revealed these domains to be stiffer than the surrounding membrane. The stiffness specificity of rafts may be related to the lower diffusion rate of proteins and can be, therefore, an important property for its role as a signaling platform. During this thesis, we also introduced a new AFM imaging mode, which we called stiffness tomography . With this imaging mode, we were able to distinguish stiff materials inclusion located into the sample. A significant part of this project was the development of a post-processing software to automate the computations of the acquired data. In this book we describes the algorithms used in the open-source version of this software.

The brain is the organ that collects information from the environment, processes and stores the information, and generates behavior as and when needed. In essence, the brain makes us who we are. For this reason, understanding the biology of brain function is a great challenge and a major goal of modern science. The brain is one of the last great frontiers in science, and the unraveling of its mysteries is comparable in complexity to efforts in space exploration. Therefore, it was not a surprise that the U.S. Congress proclaimed the 1990s the Decade of the Brain, a movement also introduced by several other countries, thereby giving a chance for neuroscientists to focus on this topic and to have better conditions for their research. A fundamental goal of neuroscience is to understand how neurons generate behavior and the pathophysiology of different mental and neurological diseases. This requires, among other things, information about where these neurons are located, how they are connected, and how they communicate with each other in various physiological and pathophysiological conditions. At the end of the nineteenth century, the great neuroanatomist Santiago Ramon y Cajal recognized that neurons are the individual signaling elements of the brain. In this book, we focus on these nerve cells of the brain and the chemical molecules that allow them to talk to each other. The discovery of intercellular communication through endogenous molecules is a milestone in the history of science. It makes the brain a unique organ. Our aim is to describe recent discoveries about the basic operations of the brain and to provide an introduction to the adaptations for specific types of information processing. For example, at a chemical synapse, the presynaptic terminal liberates a transmitter substance that acts on the postsynaptic process. Thus, a synapse converts a presynaptic electrical signal into a chemical signal and back into a postsynaptic electrical signal. Current experimental evidence indicates that this assumption needs to be enlarged. Neurons can communicate in a widespread but still organized mode: transmitters released into the extracellular space may have effects on distant extrasynaptic receptors, exerting a tonic effect. Neurons are able to release their transmitters locally into the extracellular space, where the transmitter diffuses slowly over some distance and influences many other neurons. The notion that the amount of transmitter released by an effective action potential arriving at the nerve terminal is not constant but can be modulated by the chemical environment in the vicinity of the release site is now well accepted, as also the effect of transmitters on postsynaptic sites.
This book discusses the emergence of a new class of genes with a specific anticancer activity. These genes, recently defined as "Anticancer Genes", are reviewed in individual chapters on their mode of action, the specific cell death signals they induce, and the status of attempts to translate them into clinical application.Anticancer Genes provides an overview of this nascent field, its genesis, current state, and prospect. It discusses how Anticancer Genes might lead to the identification of a repertoire of signaling pathways directed against cellular alterations that are specific for tumor cells.With contributions from experts worldwide, Anticancer Genes is an essential guide to this dynamic topic for researchers and students in cancer research, molecular medicine, pharmacology and toxicology and genetics as well as clinicians and clinical researchers interested in the therapeutic potential of this exciting new field.
