The dual-cylinder parallel balance oil circuit is an important heavy-duty support mechanism.Driven by the automation and unmanned trend NPG-Surcharge of equipment in various industries, the internal leakage analysis and corresponding fault diagnosis for this mechanism are increasingly being valued.To solve this problem, verified by numerous simulat
Submerged floating tunnels (SFTs) are innovative structural solutions to waterway crossings, such as sea-straits, fjords and lakes.As the width and depth of straits increase, the conventional structures such as cable-supported bridges, underground tunnels or immersed tunnels become uneconomical alternatives.For the realization of SFT, the structura
Age-related cataract (ARC) is the predominant cause of global blindness, linked to the progressive aging of the lens, oxidative stress, perturbed calcium homeostasis, hydration irregularities, and modifications in crystallin proteins.Currently, surgical intervention remains the sole efficacious remedy, albeit carrying inherent risks of complication
Abstract Harmonic mode-locking, realized actively or passively, is an effective technique for increasing the repetition rate of ultrafast lasers.It is critically important to understand how a harmonically mode-locked pulse train responds to external perturbations and noise, so as to make sure that it is stable and resistant to noise.Here, in a seri
[Objective] The aim of this study was to reveal the pattern of change of water resource efficiency in cascade hydropower development, in order to improve the water resource efficiency of cascade hydropower development and promote water-saving development.[Methods] We employed the panel data of 22 hydropower development basins in China from 1996 to
