To perform a high resolution and long stroke application in optical precision instruments, a linear piezoelectric actuator operated in stick-slip/scan modes for driving a linear motion table is presented.The proposed piezoelectric actuator is a piezoelectric composite structure, which includes a metal elastomer, a piezoelectric stack, and a frictio
Data based intelligent fault diagnosis is a critical tool LIP SHIMMER GUAVA for the healthy development of industry process.In actual industrial production, there are often a few or even no labeled samples for target monitoring problem, while large amounts of training data come from different but related diagnosis task under variable working condit
Imperforate hymen, though a congenital anomaly, usually presents late in puberty as lower abdominal pain, primary amenorrhea, and cyclical pain.Blood collects in vagina and uterus, proximal to imperforate hymen leading to their distention.Its presentation at infancy is a rare entity.We report such a rare Dildos case of symptomatic imperforate hymen
Abstract In living organisms, cells synergistically couple cascade reaction pathways to achieve inter- and intracellular signal transduction by transmembrane protein receptors.The construction and assembly of synthetic receptor analogs that can mimic such biological processes is a central goal of synthetic biochemistry and bionanotechnology to endo
