Characterized by obesity, insulin resistance, dyslipidemia, and hypertension, metabolic syndrome is associated with the risks of type 2 diabetes mellitus and cardiovascular disease. Obesity, which increases the incidence of atherosclerotic cardiovascular disease and subsequently leads to increased stress and inflammation, appears to play a...
SOFT OR HARD? Hardware switches can cost tens of millions and occupy a city block in real estate. Softswitches are a fraction of the cost and the size of a refrigerator. Bypassing big iron can also make for a more efficient development environment, potentially offering more...
The first comprehensive history of the Information Age how we got there and where we are going
The exchange of information is essential for both the organization of nature and the social life of mankind. Until recently, communication between people was more or less limited by geographic proximity. Today, thanks to ongoing innovations in...
A comprehensive survey by leading basic and clinical researchers of the signal transduction mechanisms responsible for lung inflammation, including vascular hyperpermeability, white cell accumulation, and vascular remodeling. The authors cut across disciplines to bring together a broad-based presentation of inflammatory challenge, both in the...
Having dealt with in-depth analysis of SS#7, GSM and GPRS networks I started to monitor UTRAN interfaces approximately four years ago. Monitoring interfaces means decoding the data captured on the links and analysing how the different data segments and messages are related to each other. In general I wanted to trace all messages...
Widely adopted by service providers to enable IP telephony, instant messaging, and other data services, SIP is the signaling protocol of choice for advanced multimedia communications signaling. Compiled by noted engineering experts Syed Ahson and Mohammad Ilyas, SIP Handbook: Services, Technologies, and Security of Session Initiation...
Session Initiation Protocol (SIP) was conceived in 1996 as a signaling protocol for inviting users to multimedia conferences. With this development, the next big Internet revolution silently started. That was the revolution which would end up converting the Internet into a total communication system which would allow people to talk to each other,...
Go under the hood of an operating Voice over IP network, and build your knowledge of the protocols and architectures used by this Internet telephony technology. With this concise guide, you’ll learn about services involved in VoIP and get a first-hand view of network data packets from the time the phones boot through calls and...
For over a hundred years of modern telecommunication history, public telephone communication has taken place over some form of a circuit switch transmission, which has evolved in its own right from analog to digital and from fixed to mobile networks. Now with the coming of IP Multimedia Subsystem (IMS) technology, which merges the Internet world...
Optical Network Control is the first expert guide and single-source reference for controlling and managing optical networks. This book fills the gap between optical network engineering and routing/signaling-helping both optical and IP professionals build networks that are more robust, flexible, manageable, and profitable. Coverage includes:...
VoIP is poised to take over from the century-old public switched telephone network (PSTN). But VoIP telephony does not enjoy the same privacy as the old PSTN. This is because PSTN phone calls were based on establishing a “closed circuit” between the two parties, while VoIP phone calls send packets through the Internet, which...
Lipid peroxidation is an important cellular process which can lead to detrimental effects if it is not regulated efficiently. Lipid hydroperoxide is formed in an initial step of lipid peroxidation. Lipid hydroperoxide is also known as a potential source of singlet oxygen. Harmful aldehydes are formed when the lipid hydroperoxide is degraded....
