Adaptation is one of the fundamental functionalities of Cognitive Radio Systems (CRS). Adaptation refers to theability of the radio to adapt its operating parameters in response to varying stimuli.Choice of the best parameter set of the radio to achieve certain objectives in shortest time possible remains one of the most challenging tasks in Cognitive Radio (CR) research.One possible approach t...

Under the canopy, far-red (FR) light represses seed germination by inactivating phytochrome photoreceptors. This elicits a decrease in gibberellins (GA) levels and an increase in abscisic acid (ABA) levels. GA promotes germination by enhancing the proteasome-mediated destruction of DELLA repressors. ABA prevents germination by stimulating the expression of ABI repressors. How phytochromes elici...

In this paper, we propose new pipelined request-grant-accept (RGA) and request-grant (RG) maximal size matching (MSM) algorithms to achieve speedup in combined input and output queueing (CIOQ) switches. To achieve a speedup factor , in the proposed pipelined RGA/RG MSM algorithms, we pipeline operations of finding matchings in scheduling cycles based on the observation that all matched inputs/o...

Caenorhabditis elegans embryos establish cortical domains of PAR proteins of reproducible size before asymmetric cell division. The ways in which the size of these domains is set remain unknown. Here we identify the GTPase-activating proteins (GAPs) RGA-3 and RGA-4, which regulate the activity of the small GTPase RHO-1. rga-3/4(RNAi) embryos have a hypercontractile cortex, and the initial relat...

in practice, obtaining the global optimum for the economic dispatch {bf (ed)}problem with ramp rate limits and prohibited operating zones is presents difficulties. this paper presents a new andefficient method for solving the economic dispatch problem with non-smooth cost functions using afuzzy adaptive genetic algorithm (faga). the proposed algorithm  deals  with the issue ofcontrolling the ex...

Pek et al. describe how a stable, intron-derived RNA regulates the expression of its host gene during Drosophila embryogenesis. Once they are spliced out of nascent mRNAs, noncoding intron sequences are usually degraded rapidly. At least in Xenopus eggs and human cell lines, however, some intronic RNAs persist for long periods, although the function of these stable intronic sequence (sis) RNAs ...

A reporter gene assay (RGA) that uses a mouse liver recombinant Hepa1c1c7 containing the firefly luciferase gene was developed to screen for dioxins in human plasma. For a high-sensitivity method, the addition of cycloheximide to the culture medium brought about a fivefold increase in the sensitivity. The detection limit was 0.1 pg/microL/well. Aryl hydrocarbon receptor (AhR) binding affinity f...

This paper proposes an application of Differential Evolution (DE) to Reactive Power Planning (RPP) problem. Simulation results, compared with those obtained by using the Real coded Genetic Algorithm (RGA) and Evolutionary Programming (EP) are presented to show that the present method is better for power system planning. In the case of optimization of non-continuous and nonsmooth function, DE gi...

Improving ATC is important in the current deregulated environment of power systems. In this paper, ATC is computed using Continuous Power Flow (CPF) method considering line thermal limit and bus voltage limits. Flexible Alternating Current Transmission system (FACTS) can control magnitude of voltage, phase angle and circuit reactance and the load flow may be re-distributed to regulate bus volta...
