With a fiber pigtailed electro-optic modulator as the active Q-switch, mode-hopping-free single-longitudinal-mode pulses are generated by a ring cavity fiber laser based on the injection seeding technique.The experimental results show that the circuiteer ii blower single-longitudinal-mode oscillating properties of the laser may be determined by the
SCRAPPER, which is an F-box protein encoded by FBXL20, regulates the frequency of the miniature excitatory synaptic current through the ubiquitination of Rab3-interacting molecule 1.Here, we recorded the induction of long-term potentiation/depression (LTP/LTD) in CA3-CA1 synapses in moen vichy bathroom faucet E3 ubiquitin ligase SCRAPPER-deficient
under armour 1364182 Under the alternating load, the chain of high-speed heavy-duty bucket hoist passes through hundreds of thousands or more shocks, and the final failure mode is mainly chain plate fatigue fracture.There is no report on this kind of chain fatigue tester at home and abroad.Through force analysis of chain plate, theoretical basis is
The wave glider is an ocean-wave-propelled autonomous marine vehicle with unique dual-body architecture, which can converse the energy obtained from the ocean wave into the forward thrust.In this paper, the dynamic models of the submerged glider based on dynamic characteristics of nautica voyage hajuvesi tandem hydrofoils and the surface float were
