“Triple Play”is a combination of Internet access, voice communication (telephony), and entertainment services such as IP television and video on demand.
The erosion of the traditional voice service, together with the ever-increasing competition between companies, is pushing the telecommunications industry...
This volume looks at the latest developments in studying calcium signaling. The chapters in this book discuss topics such as in vitro and in vivo analyses in model systems; methods to measure Ca2+ in different subcellular compartments; single Ca2+ channels; methods to measure cellular ROS and ATP; and the functionality of the ATP...
UMTS is real. In a continuously growing number of countries we can walk in the stores of
mobile network operators or resellers and take UMTS PC cards or even third-generation (3G)
phones home and use them instantly. Every day the number of equipments and their feature
sets gets broader. The “dream” of multimedia on mobile...

In just a few short years the Internet has evolved from a tool that technologists dabbled with to one that consumers are actively using. This has radically altered the way business is conducted and set off a firestorm of change and growth in wireless telecommunications. In this book network expert P. J. Louis offers a technical insider¿s...
Cutting-edge articles review our current understanding of lipid microdomain signaling mechanisms and their physiological and pathological importance. The book describes the role of lipid rafts in learning, memory, and cancer, presents the emerging evidence that lipid rafts play critical roles in signaling pathways and the regulation of...
Information processing and information flow occur in the course of an organism's development and throughout its lifespan. Organisms do not exist in isolation, but interact with each other constantly within a complex ecosystem. The relationships between organisms, such as those between prey or predator, host and parasite, and between mating...
Cytokines and cytokine receptors remain an area of great interest for the development of targeted therapies for cutaneous inflammatory diseases. Anti-TNF therapeutics have proven to be effective in the treatment of psoriasis, and clinical investigations have now begun for other cytokine-directed therapies, such as those targeting IFN-g,...
Raves for Dr. Johnson's previous classic, High-Speed Digital Design!
"....one of the finest efforts to come along in the field of applied high-speed digital design because of its focus on providing tools for the whole design team bringing a high-speed product to life. For all the PCB designers and...
Although phosphorylation of proteins on tyrosine is relatively rare compared to phosphorylation on serine or threonine residues, the past two decades of research into PTP function have led to a great appreciation of the critical role PTPs have in regulating basic cellular processes. Among these important roles is the regulation of cellular...
Voice telephony was arguably the first telecommunications service to achieve truly widespread deployment. Data services came into their own much later. To be sure, data telecommunication (in the form of smoke signals and other visual semaphore schemes, for example) has been around for a very long time. Note also that the telegraph preceded the...
