In order to solve the problem of limited driving speed of piezoelectric actuators when the piezoelectric components are small and the driving frequency is low.This paper proposes a bi-directional piezoelectric stick-slip actuator, which mainly utilizes the combination of flexible drive foot and lever amplification mechanism to realize the displacem

A robust adaptive chattering-free sliding mode (ACFSM) control method for electronic throttle (ET) system is proposed in this Women’s wallet paper.It is well known that nonlinearities in the throttle system including friction, return-spring, limp-home (LH) and gear backlash affect the control accuracy of the throttle valve.Compared with the tradi

Oral mucosa and salivary gland are composed of complex and dynamic networks of extracellular matrix, Women’s wallet multiple cell types, vasculature, and various biochemical agents.Two-dimensional (2D) cell culture is commonly used in testing new drugs and experimental therapies.However, 2D cell culture cannot fully replicate the architecture, ph

Dzhangar has a special place among texts of the folklore corpus, as it is considered to be the basic epic text of the Oirat-speaking ethnoses, having both regional and local versions.The analysis of the lexical structure of the Kalmyk version of the epic and namely of the Buddhist lexis, reflecting images of their creators regarding the religious a
