Owing to the unique structure and enriched surface ketonic carbonyl group, nanodiamond (ND) shows excellent catalytic performance for dehydrogenation reaction. However, the agglomeration of predispers...
A study in mice shows that an experimental small molecule helped restore the removal of damaged mitochondria from dopamine-producing brain cells.
Sometimes 3D printers mess up. They extrude too much material, or too little, or deposit material in the wrong spot. But what if this bug could be turned into a (fashionable) feature?
This work presents the combination of Deep-Learning (DL) and image processing to produce an automated cracks recognition and defect measurement tool for civil structures. The authors focus on tunnel c...
An emerging class of atomically thin materials known as monolayer semiconductors has generated a great deal of buzz in the world of materials science. Monolayers hold promise in the development of tra...
A novel registration algorithm using Local consistency of point dispersion (LCPD) is proposed, which is based on a new type of measure of consistency between two sets of point data. It is expected to ...
Freeze-dried cortical bone can be used as a biological plate, either alone or in combination with other internal fixation devices, to stabilize fractures. In addition to it conferring mechanical stabi...
A model is introduced to describe guided propagation of a linear or nonlinear pulse which encounters a localized nonlinear defect, that may be either static or breather-like one. The model with the st...
We study the A-discriminant of toric varieties. We reduce its computation to the case of irreducible configurations and describe its behavior under specialization of some of the variables to zero. We ...
A climate model is an executable theory of the climate; the model encapsulates climatological theories in software so that they can be simulated and their implications investigated. Thus, in order to ...
The selection of morphologically normal spermatozoa is critical to obtain high breeding performances in boar breeding farms and artificial insemination (AI) centers. Parameters for the selection of se...
We show theoretically that range of reflection bands and defect modes inside the band gap can be tuned by using a one-dimensional tilted photonic crystal (TPC) structure. A TPC structure is similar to...
The root system architecture of higher plants plays an essential role in the uptake of water and nutrients as well as the production of hormones. These root systems are highly branched with the format...
目的总结单中心、由同一术者完成的机器人辅助下房间隔缺损修补术的临床经验。方法2007年1月至2011年9月,115例继发孔型房间隔缺损患者接受了机器人辅助下房缺修补术。患者中位年龄35岁,中位缺损直径为28 mm。术中采用外周体外循环技术,右侧胸壁开3个直径8 mm的小孔及1个15 mm的工作孔,术者于机器人系统操控台前、三维手术视野下遥控机械臂完成房缺修补或同期三尖瓣成形。术中食道超声评估手术效...
Large numbers of aircraft composite structures were researched, and the distribution of delamination sizes and though thickness positions in the composite laminates were investigated. An experiment wa...
