Piezoelectric ceramic actuators have been widely used in nanopositioning applications owing to their fast response, high stiffness, and ability to generate large forces. However, the existence of nonlinearities such as hysteresis can greatly deteriorate the accuracy of the manipulation, even causing instability of the whole system. In this article, we have explained the causes of hysteresis bas...

i pi = 1. Many separability criteria have been found in recent years. For pure states, the problem is completely solved, e.g., by using the Schmidt decomposition [1]. For mixed states, there are separability criteria such as PPT, reduction, majorization, realignment etc. [2, 3, 4, 5, 6]. In [7] the authors have given a lower bound of concurrence for tripartite quantum states which can be used t...

This study was designed to build on recent findings that (a) factors of the tripartite model in adults are not uniformly related to all anxiety disorder dimensions as recent research has suggested (T. A. Brown, B. F. Chorpita, & D. H. Barlow, 1998; S. Mineka, D. W. Watson, & L. A. Clark, 1998), and (b) the tripartite model of emotion appears to have increasing support and utility in child sampl...

With a large number of sequenced microbial genomes available, tools for identifying groups or classes of proteins have become increasingly important. Here we present an improved pattern for the identification of cell wall-attached proteins (CWPs), a group of proteins with diverse and important functions in gram-positive bacteria. This tripartite pattern is based on analysis of 65 previously des...
