The purpose of this study was to define criteria suited to automated detection of end QRS notching and slurring and to evaluate their accuracy. One hundred resting 12 lead ECGs from young adult men, split randomly into equal training and test sets, were examined independently by two reviewers for the presence of such notching or slurring. Consensus was reached by re-examination. Logic was added...

The authors implied that the abnormal uterine artery Doppler velocimetry is one of the risk markers for preeclampsia in the second or third trimester and that its abnormality is practically defined at 22–24 weeks as bilateral notching with mean resistance index (RI) > 0.55 (i.e., > 50th centile), unilateral notching with mean RI > 0.65 (> 90th centile), or no notching with mean RI > 0.70 (> 95t...

AIM To evaluate whether implant design, glenoid positioning, and other factors influenced instability and scapular notching in reverse total shoulder arthroplasty. METHODS We retrospectively reviewed records of patients who had undergone reverse total shoulder arthroplasty by the senior author from July 2004 through October 2011 and who had at least 24 mo of follow-up. The 58 patients who met...

During hip resurfacing arthroplasty, excessive valgus positioning or surgical technique can result in notching of the femoral neck. Although mechanical weakening and subsequent fracture of the femoral neck are well described, the potential damage to the retinacular vessels leading to an ischaemic event is relatively unknown. Using laser Doppler flowmetry, we measured the blood flow in 14 osteoa...

OBJECTIVES Uterine artery Doppler flow studies during the 11th and 14th week of pregnancy are important in the prediction of preeclampsia and intrauterine growth restriction in pregnant women as well as in the prevention thereof. METHODS Our study on Doppler flow indices of the uterine arteries involved 168 patients examined in our clinic, with pregnancies ranging from 11 weeks + 0 days to 13...

Reverse shoulder arthroplasty, introduced by Grammont et al. [1] in 1987, is commonly associated with scapular notching, [2] an impingement of the humeral cup against the scapula’s inferior border. Although the clinical significance of notching has been debated, 2 studies reported less successful clinical outcomes in its presence [2,3]. A laboratory study showed that a varus humeral neck-shaft ...

We study the bunching identification strategy for an elasticity parameter that summarizes agents' response to changes in slope (kink) or intercept (notch) of a schedule incentives. A notch identifies but kink does not, when distribution agents is fully flexible. We propose new non-parametric and semi-parametric assumptions on are weaker than currently made literature. revisit original em...

 In through-wafer silicon etching using highdensity low-pressure inductively coupled plasma, a notching (or footing) effect occurs at the silicon-insulator interface. The insulator layer is common, as the silicon wafer has either an oxide layer to avoid break through of the plasma or is bonded to a handle wafer using either photoresist or other adhesives. Notching at the foot of micro-structur...

High frequency notching of the QRS complex is associated with transmural infarction, cardiomyopathies, and ventricular hypertrophy from any cause. The mechanism producing notching is unknown; but the presence of a discrete anatomic lesion is not an essential feature. The hypothesis that notching was produced by activation across, rather than along, myocardial fibers was investigated by stimulat...
