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...

Background—Atriofascicular and decremental atrioventricular pathways are variants of accessory pathways with anterograde decremental conduction properties. They result in typical wide Quantronic Resonance System (QRS) tachycardia of left bundle branch block morphology. Data on the sinus rhythm electrocardiographic characteristics are limited. Methods and Results—Thirty patients with accessory p...

Cogging torque reduction of axial flux permanent magnet brushless dc (PMBLDC) motor is an important issue which demands attention of machine designers during design process. This paper presents magnet notching technique to reduce cogging torque of axial flux PMBLDC motor designed for electric vehicle application. Reference axial flux PMBLDC motor of 250 W, 150 rpm is designed with 48 stator slo...
