As ATM becomes widely accepted as the communication standard for high speed networks, the signaling system structure and protocols that support ATM become more and more important. To support existing, future and unknown applications, the signaling system has to be very exible and e cient. In this paper we de ne the signaling problem, present several possible signaling system structures, compare...

At first glance, a 100-year-old tree and a bacterium do not have much in common. However, both plants and bacteria face a similar problem: They are confined to their environment and have to endure and adapt to a broad array of environmental conditions. To manage this complex task, prokaryotic organisms rely on the two-component signaling system, which is involved in such diverse processes as ch...

diabetic retinopathy is the lead among causes of blindness in north america. glucose-induced endothelial injury is the most important cause of diabetic retinopathy and other vascular complications. extracellular signal-regulated kinase 5 (erk5), also known as big mitogen-activated protein kinase 1 (bmk1), is a member of mitogen-activated protein kinases (mapk) family. physiologically, it is cri...

At this time, telecommunication networks are present everywhere. These networks are not only rather complex, but they are also made up of different components. That is the reason telecommunication network management (TNM) is so relevant. This paper deals with two important aspects of telecommunication network management: managed objects and expert system rules. Definition of objects is based on...

The rise of digital platforms is changing organizations, markets and the logic of innovation in the digital economy. In particular, telecommunication companies re-structure their business models to gain control of innovative services and digital platforms. In this light, we aim to advance research on digital platform business models conducting a frameworkbased case study analysis of telecommuni...

Telecommunication companies have received a great deal of research attention, which have many advantages such as low cost, higher qualification, simple installation and maintenance, and high reliability. However, the using of technical maintenance approaches in Telecommunication companies could improve system reliability and users' satisfaction from Asymmetric digital subscriber line (ADSL) ser...

Parkinson's disease (PD) is a chronic neurodegenerative condition which has the second largest incidence rate among all other neurodegenerative disorders barring Alzheimer's disease (AD). Currently there is no cure and researchers continue to probe the therapeutic prospect in cell cultures and animal models of PD. Out of several factors contributing to PD prognosis, the role of p38 MAPKs (mitog...

Background: Progesterone is indispensable for differentiation of human endometrial stromal cells (HESCs) into decidual cells, a process that critically controls embryo implantation. However, HESCs also abundantly express androgen receptors (AR), yet the role of this member of the superfamily of ligand-dependent transcription factors in the decidual process remains poorly elucidated. Materials a...

In this paper an agent based framework for service deployment in telecommunication networks is presented. The framework is intended to improve the process of service deployment in next generation telecommunication networks. This process has been complicated with the introduction of new actors and the migration of service infrastructure from the telecommunication provider to the third-party valu...

This study analyzes Kurdistan’s potential for effectively using mobile telecommunication. It identifies key factors determining the adoption of mobile telecommunication service. A conceptual model is specified, and several hypotheses are tested with a sample of 1,458 Kurdish mobile phone users in 2010. A discrete choice methodology is used to test two models of mobile telecommunication acceptan...
