The Nutcracker Syndrome: an Underdiagnosed Cause for High Grade Varicocele

Background: The nutcracker syndrome represents a clinical condition caused by compression of the left renal vein (LRV) between the superior mesenteric artery (SMA) and the aorta. One of its manifestations is left-sided varicocele. The aim of this study is to determine the prevalence of nutcracker syndrome in patients with primary and recurrent high grade left-sided varicocele. Methods: Fifty pa...

Excitation Backprop for RNNs

Deep models are state-of-the-art for many vision tasks including video action recognition and video captioning. Models are trained to caption or classify activity in videos, but little is known about the evidence used to make such decisions. Grounding decisions made by deep networks has been studied in spatial visual content, giving more insight into model predictions for images. However, such ...

Pre-excitation as a cause of appearance and increased intensity of systolic murmurs.

ASSOCIATION of cardiac murmurs with the Wolff-Parkinson-White (WPW) syndrome has been reported by several investigators .1 In the reported cases, however, the murmurs were not directly attributed to hemodynamic alterations produced by pre-excitation. This communication describes three patients with systolic murmurs related to pre-excitation. In one patient the murmur was heard only when the ele...

Studying piezoelastic and piezomagnetoelastic configurations for different excitation frequencies in MEMS energy harvesters

Typically two configurations are used for energy harvesting with different advantages: piezoelastic and piezomagnetoelastic. Best performance of the piezoelastic configuration is when the excitation frequency is close to the resonance frequency. If the input frequency slightly deviates from the natural frequency, the generated power is severely decreased. To tackle the problem, the piezomagneto...

Pole placement algorithm for control of civil structures subjected to earthquake excitation

In this paper the control algorithm for controlled civil structures subjected to earthquake excitation is thoroughly investigated. The objective of this work is the control of structures by means of the pole placement algorithm, in order to improve their response against earthquake actions. Successful application of the algorithm requires judicious placement of the closed-loop eigenvalues from ...
