Super-steep retrograded (SSR) channels were compared to uniformly doped (UD) channels as devices are scaled down from 250 nm to the 50 nm technology node, according to the scheme targeted by the National Technology Roadmap for Semiconductors (1997). The comparison was done at the same gate length Lgate and the same off-state leakage current Io , where it was found that SSR profiles always have ...

Maize with opposite phyllotaxy (OP) and also initiating ears in opposite pairs is an aberrant mutant and also precious material for maize breeding and plant evolution studies. Mapping and identifying the markers closely linked to genes for the OP trait are essential for cloning the gene and marker-assisted selection in breeding. We established H14D, a near-isogenic line of the OP trait wit...

Microsatellite or simple sequence repeat (SSR) markers have been successfully used for genomic mapping, DNA fingerprinting, and marker-assisted selection in many plant species. Here we report the first successful assignment of 15 SSR markers to the Phaseolus vulgaris molecular linkage map. A total of 37 SSR primer pairs were developed and tested for amplification and product-length polymorphism...

Genomic instability is thought to underlie tumor progression in solid tumors, such as breast cancer. Although evidence that the hereditary breast cancer genes, BRCA1 and BRCA2, are involved in DNA repair suggests that genomic instability plays an important role in hereditary breast tumorigenesis, genomic instability remains poorly characterized in sporadic breast cancers. Using a DNA fingerprin...

This paper presents an algorithm for noise removal from digital image, based on stochastic noise pattern. We apply white Gaussian noise to improve the quality of the noisy input image to get the de -noised response image. Input noisy image is subjected to independent additive white Gaussian noise of different standard deviation, the output image corresponding to individual noise standard deviat...

Simple sequence repeats (SSRs) have been demonstrated to affect normal gene function to cause different genetic disorders. Several conserved and even partial functional SSR patterns were discovered in inherited orthologous disease genes. To explore a wide range of SSRs in genetic diseases, a system focuses on orthologous SSRs for disease genes through comparative genomics mechanism is construct...

The need for the conservation of plant genetic resources has been widely accepted. Germplasm characterization and evaluation yield information for more efficient utilization of these valuable resources. The aim of the present study was to characterize the pea germplasm conserved at the Aegean Agricultural Research Institute of Turkey using morphological and simple sequence repeat (SSR)-based mo...

OBJECTIVES Men presenting with primary infertility and azoospermia may be offered surgical sperm retrieval (SSR) as a prelude to intracytoplasmic sperm injection (ICSI). We evaluated sperm retrieval rates in subgroups of men with azoospermia, based on obstructive aetiology, testicular volume and FSH. METHODS 106 patients with primary infertility underwent clinical evaluation and SSR with perc...

BACKGROUND The aim of this research was to explore the association between the left atrial (LA) and left atrial appendages (LAA) systole strain rate (SSR) in patients with atrial fibrillation (AF), and to provide evidence to aid in the assessment of disease progression. MATERIAL AND METHODS A total of 180 patients with AF were selected for the study (130 patients with paroxysmal AF (Par AF) and...
