Deep reflection seismic data are usually accompanied by large-offset data, and the accurate and rapid identification of the first arrivals of seismic records plays an important role in eliminating the effects of topography and other factors that increase with the increasing offsets.In this paper, we propose a method based on convolutional neural ne
Short-term voltage instability has a sensational effect once it occurs with massive loss of load, possibly area instability, and voltage collapse.This paper analyzes the short-term voltage instability caused by induction motor from the viewpoint of active and reactive power joint balancing.The analysis method is based on (1) custom congratulations
Variation in food stoichiometry affects individual performance and population dynamics, but it is also likely that species with different here life histories should differ in their sensitivity to food stoichiometry.To address this question, we investigated the ability of the three nettle-feeding butterflies (Aglais urticae, Polygonia c-album, and A
Abstract Background Spinal subdural hematoma (SSH) is a rare cause of compression of the neutral elements of the spinal cord.However, little is Shirt known about the presentation of acute SSH after lumbar spine surgery.The reason for this may be that symptomatic SSH occurs rarely and is not given enough attention by spine surgeons.Currently, the de
