This paper presents a generic addressing framework (GAF) which enables the development of protocol stack independent applications. This framework has been developed in the context of dynamic protocol stack composition [8]. Having a way to compose [8][7] and build [3] protocol stacks is not sufficient. The protocol layers a stack is composed of have an impact on the addressing used inside the st...

Reducing energy consumption has been a recent focus of wireless sensor network research. Topology control explores the potential that a dense network has for energy savings. One such approach is Geographic Adaptive Fidelity (GAF) (Xu et al., 2001). GAF is proved to be able to extend the lifetime of self-configuring systems by exploiting redundancy to conserve energy while maintaining applicatio...

<span>A wireless sensor network (WSN) composed by a large number of nodes that are insufficient in terms processing power, storage and energy. The principal tasks is gathering transmitting data collected to the base station (BS). Consequently major essential criteria for designing WSN lifetime. In this paper an efficient GAF routing protocol gathered introduced. It proposes energy-efficie...

Purpose To compare the intermodality and interreader agreement for geographic atrophy (GA) lesion size quantification in green-light fundus autofluorescence (GAF; excitation = 518 nm) versus combined blue-light fundus autofluorescence (BAF; excitation = 488 nm) and near-infrared reflectance (NIR; 820 nm) -based grading. Methods Confocal scanning laser ophthalmoscopy (cSLO) GAF, BAF, and NIR i...

In the design of protocols and algorithms energy awareness for computation and protocol management is becoming a crucial factor. On the other hand, to support node mobility many scalable routing strategies have been designed. These protocols try to consider the path duration with respect to some QoS constraints and to reduce the route discovery procedures. In this paper, a novel routing strateg...

GAF domains were first described for vertebrate cGMP-specific phosphodiesterases, a cyanobacterial adenylate cyclase and the bacterial formate hydrogen lyase transcription activator FhlA [1]. GAF domains consist of about 150 amino acids conserved in many signaling molecules. GAF domains (PF01590) can be identified in the Pfam database by their characteristic protein sequence signature. GAF doma...

Previous studies have shown that GAGA Factor (GAF) is enriched on promoters with paused RNA Polymerase II (Pol II), but its genome-wide function and mechanism of action remain largely uncharacterized. We assayed the levels of transcriptionally-engaged polymerase using global run-on sequencing (GRO-seq) in control and GAF-RNAi Drosophila S2 cells and found promoter-proximal polymerase was signif...

The purpose is to schedule redundant nodes into energy-saving mode, while maintaining the connectivity of a network for simple geographic routing protocols. Comparing to GAF, the number of cells as well as the overall energy consumption of a WSN also drops dramatically with the proposed protocol.

BACKGROUND Assessment of psychosocial functioning in people with schizophrenia is important. The Global Assessment of Functioning (GAF-F) scale represents a widely applied, easy, and quick tool, but its validity and reliability have been debated. The aim was to investigate whether GAF-F scores are associated with other indicators of functioning, severity, and hospitalization. METHODS A Danish...
