Within vertebrates, major sex determining Console Access Cover genes can differ among taxa and even within species.In zebrafish (Danio rerio), neither heteromorphic sex chromosomes nor single sex determination genes of large effect, like Sry in mammals, have yet been identified.Furthermore, environmental factors can influence zebrafish sex determin
To understand the anisotropy dependence of the damage evolution and material removal during the machining process of MgF _2 single crystals, nanoscratch tests of MgF _2 single crystals with different crystal planes and directions were systematically performed, and surface morphologies of the scratched grooves under different conditions were analyze
Abstract Ignition advance angle is one of the important factors affecting the performance of the engine, when it occurs abnormally will make the engine power and economy worse, and even cause serious damage to the engine.Therefore, it is very necessary to recognize the abnormal ignition advance angle of the engine.However, the engine system is clos
A retaining wall was practically developed to provide lateral support for soil, and it is widely used in underground projects, highway barriers, and mines as well as for aesthetic considerations and slope stabilization.This type of earth structure member can carry machine foundation load simultaneously with traditional static load.This study carrie
Abstract The migration of rivers in permafrost landscapes has critical implications for riverine infrastructure, ecosystem stability, Counter/Bench Brushes and carbon cycling, yet its magnitude and underlying mechanisms remain poorly understood.Here, we leverage four decadal satellite imagery, hydrological observations, and permafrost modeling to i
