prostate-specific antigen (psa) was purified to homogeneity from human seminal plasma by ion-exchange chromatography on a cm-sephadex c-50 and by gel filtration on a sephacryl s-200 column. a single 33-kda protein band appeared in sds-page. high pressure liquid chromatography (hplc) of the purified protein produced a single peak, while isoelectric focusing demonstrated the presence of five diff...

The multi-scale finite element method is used to study the vibrational characteristics of polymer matrix reinforced by single-walled silicon carbide nanotubes. For this purpose, the nanoscale finite element method is employed to simulate the nanotubes at the nanoscale. While, the polymer is considered as a continuum at the larger scale. The polymer nanotube interphase is simulated by spring ele...

In any VLSI circuit, power consumption is very important factor that should be taken into consideration. Generally, dynamic power consumption is more dominant when compared to that of static. To reduce the internal switching activity rate of the circuit under test (CUT), we can recombine testing vector to raise the correlation between testing vector. Random Single Input Change (RSIC) test theor...

Genome-wide association studies (GWAS) have successfully identified a large number of genetic variants associated with complex traits, but these only explain a small proportion of the total heritability. It has been recently proposed that rare variants can create 'synthetic association' signals in GWAS, by occurring more often in association with one of the alleles of a common tag single nucleo...

OBJECTIVE Clinically, attention-deficit/hyperactivity disorder (ADHD) is characterized by hyperactivity, impulsivity, and inattention and is among the most common childhood disorders. These same traits that define ADHD are variable in the general population, and the clinical diagnosis may represent the extreme end of a continuous distribution of inattentive and hyperactive behaviors. This hypot...

OBJECTIVE The purpose of this study was to evaluate the audiologic and clinical characteristics of the tinnitus in single-sided deafness (SSD) patients and to determine whether tinnitus retraining therapy (TRT) is beneficial to those patients who suffer from tinnitus with SSD. MATERIALS AND METHODS Thirty-six tinnitus patients with unilateral sensorineural profound hearing loss were included ...

As large-scale sequencing efforts turn from single genome sequencing to polymorphism discovery, single nucleotide polymorphisms (SNPs) are becoming an increasingly important class of population genetic data. But because of the ascertainment biases introduced by many methods of SNP discovery, most SNP data cannot be analyzed using classical population genetic methods. Statistical methods must in...

This paper proposed analytical solutions for the buckling analysis of rectangular single-layered graphene sheets under in-plane loading on all edges simply is supported. The characteristic equations of the graphene sheets are derived and the analysis formula is based on the nonlocal Mindlin plate. This theory is considering both the small length scale effects and transverse shear deformation ef...
