calcineurin (can) is a ca2+/calmodulin (ca2+/cam)-dependent serine/threonine protein phosphatase expressed in most mammalian tissues but found at higher concentration in brain. in the last decade there have been a steadily increasing number of studies identifying neuronal can as a primary suspect in neuronal vulnerability, synapse loss, dendritic atrophy, synaptic dysfunction and neuroinflammat...

In this paper, we present a dynamic congestion management mechanism called DWRED (Dynamic Weighted RED) that enhances the well-known congestion avoidance Random Early Detection (RED) algorithm, by providing service for multiple classes of traffic as well as dynamic parameters modifications using the communicating agents concepts of MultiAgents Systems. We also propose a simple DWRED prototype i...

The IETF Differentiated Services Working Group has recently standardized the Assured Forwarding (AF) Per Hop Behavior (PHB). RFC 2597 recommends that an Active Queue Management (AQM) technique be used to realize the multiple levels of drop precedence required in the AF PHB. The most widely used AQM scheme is RED (Random Early Detection). There are several ways to extend RED to a Multilevel RED ...

----------------------------------------------------------------------ABSTRACT------------------------------------------------------------------In wireless networks, resource management is a very complicated issue because of scarcity in resources. This paper presents a fuzzy based packet dropping scheme for wireless networks in the context of future generation cellular networks. In this scheme,...

<span>Network congestion is still a problem on the internet. The random early detection (RED) algorithm being most notable and widely implemented in routers faces problems of queue instability large delay arising from presence an ineffectual singular linear packet dropping function. This research article presents refinement to RED, named quadratic exponential (QERED) algorithm, which expl...

conclusions both task-related and resting fmri techniques have the potential to detect early brain dysfunction related to ad. however, the use of fmri in ad populations thus far has been limited to a relatively small number of research groups. results bold fmri is considered to reflect the joined synaptic activity of neurons through mri signal changes because of alterations in blood flow, blood...

introduction: newborn hearing screening leads to the early detection of hearing impairment. the aim of screening is to decrease or remove the effect of hearing impairment on development of speech and language by timely diagnosis and effective treatment. a number of risk factors lead to delayed start of decreased hearing ability including: 1. congenital infection with cytomegalovirus  (cmv) viru...

cell free dna (cfdna) is a genetic biomarker that is present in serum or plasma in high concentration in many types of cancer. identification of circu-lating cancer related dna molecules in serum or plasma is a non-invasive tool for early diagnosis and prognosis in many cancer patients. for this review, study selection and data extraction were performed by the authors. detection of point mutati...

Random Early Detection (RED) is one of the most commonly used Active Queue Management (AQM) algorithms that is recommended by IETF for deployment in the network. Although RED provides low average queuing delay and high throughput at the same time, but effectiveness of RED is highly sensitive to the RED parameters setting. As network condition varies largely, setting RED's parameters with fixed ...
