The concept of attraction has been shown to play a basic role in the synthesis of supervisors for stabilizing discrete-event processes. In this paper we define and investigate optimal attraction optimal in the sense that the cost (or distance) of the convergence path is as small as possible with respect to some distance measure. We find conditions for the existence of supervisors achieving opti...

A model of narcissism and romantic attraction predicts that narcissists will be attracted to admiring individuals and highly positive individuals and relatively less attracted to individuals who offer the potential for emotional intimacy. Five studies supported this model. Narcissists, compared with nonnarcissists, preferred more self-oriented (i.e., highly positive) and less other-oriented (i....

MPhylogenetic analyses of hundreds of genes from model animals have placed flies closer to vertebrates than to nematodes; recent work suggests this may be due to an artefact known as long branch attraction.

In this paper we present an original method for Bayesian localisation based on particle approximation. Our method overcomes a majority of problems inherent in previous Kalman filter and Bayesian approaches, including the recent Monte Carlo Localisation methods. The algorithm converges quickly to any desired precision. It does not overconverge in the case of highly accurate sensor data and thus ...

As we learned from mean-field theory, like-chared particles repel. However, in the last decade, like-charge polyelectrolyte attraction was observed in the presence of multivalent ions in a variety of biological systems, including DNA, F-actin, microtubules, and filamentous viruses. Considering the fundermental role DNA played in the lifecycle, we find like-charge attraction is not only physical...

introduction: today the market of medical tourism is growing as one of the competitive and profitable industries in the world. the aim of this study was to determine medical tourist attraction in tehran hospitals. methods: this is a descriptive study which was carried out in 8 hospitals of tehran in 2012. 195 people from the managing boards of these hospitals participated in the study. a questi...

The Casimir attraction can significantly interfere the physical response of nanoactuators. The intensity of the Casimir force depends on the geometries of interacting bodies. The present paper is dedicated to model the influence of the Casimir attraction on the electrostatic stability of nanoactuators made of cylindrical conductive nanowire/nanotube. An asymptotic solution, based on path-integr...

Time delayed feedback control is well known as a practical method for stabilizing unstable periodic orbits embedded in chaotic attractors. However, this control method still has an open problem of estimating domain of attraction for target unstable periodic orbits. In this paper, we numerically discuss the domain of attraction in Duffing systems under the control method. The disturbance to init...

A decaying cadaver emits volatile organic compounds that are used by necrophilous and necrophagous insects in order to find their brood substrate. Although volatile organic compounds (VOCs) that are released by carcasses have been identified, little is known about the specific compounds that are used by these insects while searching for a brood substrate. Therefore, we have investigated the che...
