Gravity waves (GWs) have been intensively studied over recent decades because of their dominant role in the dynamics of the mesosphere and lower thermosphere (MLT).The momentum deposition caused by breaking GWs determines the basic structure and drives the large-scale circulation in the MLT.Satellite observations provide a way to qualify the proper
It is easy to think of using sawtooth steel plate on the surface of column to increase the interfacial friction in the temporary RC column underpinning structure.However, there is little research on the friction properties between sawtooth steel plate and concrete.108 working condition of double interface shear tests were conducted for measuring th
The operation disturbance induced by the solar array drive system (SADS) and the residual vibration of solar array following the attitude adjustment of the spacecraft obviously affect the dynamics environment, quick stabilization, and attitude stability of the high-precision spacecraft.However, these two kinds of vibration disturbance are character
Abstract Objective The purpose of this study is to explore whether electrical impedance tomography (EIT)-guided individualized positive end-expiratory pressure (PEEP) can reduce the incidence of pulmonary complications within 1 week following a craniotomy compared with a single PEEP (PEEP = 6 cmH2O) from dura suturing to extubation.Methods A random
