Mammalian physiology is governed by a complex circadian timing system that involves interacting positive and negative transcriptional feedback loops. A key role in this feedback loop was attributed to the PAS domain helix-loop-helix protein CLOCK, on the basis of a dominant-negative mutation in this transcription factor. However, recent experiments by Reppert and coworkers with Clock knockout m...
objectives: dental caries is a public health problem that affects pre-school and school children throughout the world. poor oral health profoundly affects a person’s quality of life. information on caries prevalence and severity represents the basis for caries prevention programs and indicates treatment necessity in the population. the occurrence of permanent teeth caries particularly in non-in...
Introduction: Lack of effective control in postoperative pain can cause sleep disturbance, decreased fluid intake and incidence of behavioral changes, such as restlessness, irritability and reduced activity and play. Therefore, this study was performed with the aim of determining the effectiveness of Around-The-Clock (ATC) analgesic administration on the quality of sleep and behavioral chan...
Multi-Supply voltage design using Cluster Voltage Scaling (CVS) is an effective way to reduce power consumption without performance degradation. One of the major issues in this method is performance and power overheads due to insertion of Level Converting Flip-Flops (LCFF) at the interface from low-supply to high-supply clusters to simultaneously perform latching and level conversion. In this p...
Quantum dot cellular automata (QCA) introduces a pioneer technology in nano scale computer architectures. Employing this technology is one of the solutions to decrease the size of circuits and reducing power dissipation. In this paper, two new optimized FlipFlops with reset input are proposed in quantum dot cellular automata technology. In addition, comparison with related works is performed.Th...
