BACKGROUND AND PURPOSE WAKE-UP is a randomized, placebo-controlled MRI-based trial of thrombolysis in wake-up stroke using the mismatch between a lesion's visibility in diffusion-weighted imaging and fluid-attenuated inversion recovery (FLAIR) sequences as its main imaging inclusion criterion. Visual judgment of lesion conspicuity on FLAIR is however methodically limited by moderate inter-rater...
An increased awareness of environmental protection and sustainable production raise the necessity incorporating selection low nitrogen-tolerant winter wheat cultivars for high yield quality in breeding process. This can be assisted by using stress screening indices. Our study aimed to evaluate compare a number indices determine select most nitrogen deficiency-tolerant further breeding. The expe...
technical analysis for 40 years and was a true believer. However, his faith in the effectiveness of technical analysis was shaken in the summer of 2000, just after the technology bubble burst. At the time, Aronson, 61, worked as a proprietary trader for Spear, Leeds, and Kellogg and had been profitable for four years. He used standard technical analysis techniques — interpreting classic chart p...
BACKGROUND AND PURPOSE In acute stroke, the DWI-FLAIR mismatch allows for the allocation of patients to the thrombolysis window (<4.5 hours). FLAIR-lesions, however, may be challenging to assess. In comparison, DWI may be a useful bio-marker owing to high lesion contrast. We investigated the performance of a relative DWI signal intensity (rSI) threshold to predict the presence of FLAIR-lesions ...
The postural stability of bipedal robots is investigated in perspective of foot-rotation during locomotion. With foot already rotated, the biped is modeled as an underactuated kinematic structure. The stability of such biped robots is analyzed by introducing the concept of rotational stability. The rotational stability investigates whether a biped would lead to a flat-foot posture or the biped ...
BACKGROUND Although chronic obstructive pulmonary disease (COPD) is closely associated with gastroesophageal reflux disease (GERD), the clinical significance of laryngopharyngeal reflux (LPR) is not fully understood in COPD. METHODS Prospective cohorts were established among 118 patients with COPD from March 2013 to July 2014. Thirty-two age-matched and sex-matched normal controls, who had ro...
BACKGROUND Laryngopharyngeal reflux (LPR) disease has many symptoms such as globus pharyngeus, excessive throat clearing and hoarseness. The aim of this study was to investigate the effect of stellate ganglion block (SGB) in addition to proton pump inhibitors (PPI) on LPR. METHODS Fifty patients complaining of more than 3 typical LPR symptoms for over 3 months were enrolled in the study. The ...
In order to evaluate the effect of terminal moisture stress on 20 barley promising lines (Hordeum vulgare) and for determination of their relative tolerance, an experiment was conducted based on randomized complete blocks design with three replications in growing season of 2010-2011. In this research some old indices such as, stress susceptibility index (SSI), tolerance index (TOL), mean produc...
Mutations in glucokinase (GCK) cause a spectrum of glycemic disorders. Heterozygous loss-of-function mutations cause mild fasting hyperglycemia irrespective of mutation severity due to compensation from the unaffected allele. Conversely, homozygous loss-of-function mutations cause permanent neonatal diabetes requiring lifelong insulin treatment. This study aimed to determine the relationship be...
We derive the mutual information (MI) of the wireless links in a buffer-aided full-duplex (FD) multiple-input multiple-output (MIMO) relaying network. The FD relay still suffers from residual selfinterference (RSI), after the application of self-interference mitigation techniques. We investigate both cases of the slow-RSI channel, where the RSI is fixed over the entire codeword, and the fast-RS...
