Stationary and pursuit fixation may involve different fixation mechanisms that are reflected by differences in saccadic reaction times (SRTs). Gap, Simultaneous, and Overlap interval paradigms provided three distinct SRT ranges for comparisons between these two viewing conditions. SRTs following pursuit fixation were longer than following stationary fixation, but were similarly affected by the ...

The authors investigated perceptual learning of a novel accent in young and older listeners through measuring speech reception thresholds (SRTs) using speech materials spoken in a novel-unfamiliar-accent. Younger and older listeners adapted to this accent, but older listeners showed poorer comprehension of the accent. Furthermore, perceptual learning differed across groups: The older listeners ...

Genes for two group 1 beta-lactamases, SRT-1 and SST-1, were sequenced. These beta-lactamases were produced by clinical isolates of Serratia marcescens, isolates GN16694 and GN19450, respectively. The resulting enzymes were 96% identical. SRT-1 hydrolyzed oxyimino cephalosporins, but SST-1 hardly hydrolyzed them. At residue 213 in the third motif, which is conserved among group 1 beta-lactamase...

PURPOSE To evaluate the efficacy and toxicity of CyberKnife stereotactic radiotherapy (SRT) for recurrent glial tumors previously treated with high-dose radiotherapy. METHODS CyberKnife SRT was performed in 37 patients with recurrent glial tumors who presented to our hospital between January 2007 and March 2012. The patients were subjected to a dose ranging from 20 to 28 Gy using the CyberKni...

Background. Previous reports have shown a positive association between serum calcium level and prostate cancer mortality. However, there is no data regarding whether higher serum calcium levels are associated with increased risk of biochemical recurrence (BCR) following salvage radiation therapy (SRT) for prostate cancer. Herein, we evaluate the association between pretreatment serum calcium le...

In this first paper of a series we develop a new technique to analyze clusters of galaxies observed during the ROSAT All-Sky Survey (RASS). We call this method the Steepness Ratio Technique (SRT). The SRT uses the convolution between the real RASS point-spread function and the cluster emission profile assumed to be a β-model with the β parameter fixed to the value of 2/3. From the convolved sou...

In order to address the question of whether the basal ganglia are involved exclusively in regulation of motor sequence learning, or if they are involved in non-motor sequence learning as well, two versions of the serial reaction time (SRT) task were administered: First is the standard version of the SRT task in which the sequence is executed motorically, and the second is a non-motor version of...

Thirteen nondemented patients with Parkinson's disease (PD) were compared with age-matched controls on two standard tests of implicit learning. A verbal version of the Serial Reaction Time (SRT) task was used to assess sequence learning and an artificial grammar (AG) task assessed perceptual learning. It was predicted that PD patients would show implicit learning on the AG task but not the SRT ...

One of the main factors affecting membrane fouling in MBRs is operational conditions. In this study the influence of aeration rate, filtration mode, and SRT on hollow fiber membrane fouling was investigated using a triple fouling layers perspective. The sludge microbial population distribution was also determined by PCR method. Through various applied operational scenarios the optimal condition...

Acute respiratory tract infections are leading causes of morbidity in poultry farms throughout the world. Avian pneumovirus (APV), avian influenza virus (AIV), and Newcastle disease virus (NDV) have been recognized as the most important pathogens of both chicken and turkeys. Single-virus reverse transcription-polymerase chain reaction (sRT-PCR) assays are used extensively to detect these viruse...
