Reactive jamming attacks have been considered as one of the most lethal and disruptive threats to subvert or disrupt wireless networks since they attack the broadcast nature of transmission mediums by injecting interfering signals.Existing countermeasures for the Internet against reactive jamming attacks, i.e., channel surfing or frequency hopping,

Collagen fibrils were reconstituted in vitro from type I collagen solution.The reconstituted collagen fibrils show-blouse-garnet and chondroitin sulfate B were deposited alternately.The adsorbed weight of the collagen fibrils and chondroitin sulfate B was measured using a quartz crystal microbalance (QCM) and their microstructure was observed using

The ability of a firm to endure, adapt and prosper over time is a multifaceted outcome influenced by an interplay of internal and external factors.However, the precise mechanisms and specific dynamics that contribute to sustained firm survival remain unclear.This study investigated the moderating effect of risk management committee on the relations

Introduction.Phenylketonuria is an inborn metabolism error with a high phenotypical variability, due in part to the large number of implicated genetical variants (over 1200 reported) but also due to other factors.Establishing a genotype=phenotype correlation, ABSOLUT ARNICA accessible today through molecular testing, is an important instrument for
