Background The androgen receptor (AR) gene contains a polymorphic trinucleotide repeat that encodes a polyglutamine tract in its N-terminal transactivation domain (NTAD). We aimed to find a correlation between the length of this polymorphic tract and azoospermia or oligozoospermia in infertile men living in Khuzestan, Iran.

In recent years, researches on reinforcement learning (RL) have focused on bridging the gap between adaptive optimal control and bio-inspired learning techniques. Neural network reinforcement learning (NNRL) is among the most popular algorithms in the RL framework. The advantage of using neural networks enables the RL to search for optimal policies more efficiently in several real-life applicat...

in order to genetic analysis of rice seed vigour, a cross was carried out between tarom mahalli (tolerant to osmotic stress) and khazar (sensitive to osmotic stress) crosses. linkage map based on ssr markers was derived using 74 polymorphic markers and 192 f2 individuals. germination rate, radicale and plumule length were recorded from 20 plants per 192 f3 families. the loci related to germinat...

twenty accessions of cultivated grass pea (lathyrus sativus l.) and wild species of lathyrus l.collected from western and southern regions of iran were evaluated for their mitotic metaphase chromosomalcharacteristics. all populations comprising 16 populations of cultivated l. sativus and 4 wild populations oflathyrus l. were diploid, 2n=2x=14 chromosomes. there were significant variations among...

this paper presents an innovative active power filter design method to simultaneously compensate the current harmonics and reactive power of a nonlinear load. the power filter integrates a passive power filter which is a rl low-pass filter placed in series with the load, and an active power filter which comprises an rl in series with an igbt based voltage source converter. the filter is assumed...

Reinforcement learning (RL) theories posit that dopaminergic signals are integrated within the striatum to associate choices with outcomes. Often overlooked is that the amygdala also receives dopaminergic input and is involved in Pavlovian processes that influence choice behavior. To determine the relative contributions of the ventral striatum (VS) and amygdala to appetitive RL, we tested rhesu...

in order to locate the qtls for plant height, peduncle length, and heading date, a set of 107 wheat doubled haploid (dh) lines derived from the cross fukuho-komugi× oligoculm was grown during the growing seasons of 2004 and 2005. a total of 36 qtls were identified based on composite interval mapping (cim) approach. all detected plant height qtl’s were stable over the two years. qtls located nea...

Salinity is a leading threat to crop growth throughout the world. Salt stress induces altered physiological processes and several inhibitory effects on of cereals, including wheat (Triticum aestivum L.). In this study, we determined salinity five spring winter genotypes seedlings. We evaluated salt root shoot attributes, i.e., length (RL), (SL), relative rate (RGR-RL), (RGR-SL). The ionic conte...
