Single-file transport, which corresponds to the diffusion of particles that cannot overtake each other in narrow channels, is an important topic out-of-equilibrium statistical physics. Various microscopic models single-file systems have been considered, such as simple exclusion process, has reached status a paradigmatic model. Several different shown be related by duality relation, holds either...

i ntroduction: the aim of this study was to compare the shaping ability of two single-file systems and conventional rotary instruments in severely curved root canals of extracted human molars. methods and materials: mesiobuccal canals of 120 mandibular molars with angles of curvature ranging between 25 ° and 35 ° and radii of curvature from 5 to 9 mm, were divided into three groups ( n =40). in...

This document describes a file format for the storage of flow data based upon the IP Flow Information Export (IPFIX) protocol. It proposes a set of requirements for flat-file, binary flow data file formats, then specifies the IPFIX File format to meet these requirements based upon IPFIX Messages. This IPFIX File format is designed to facilitate interoperability and reusability among a wide vari...

In this paper, a new modified social force model is proposed to simulate the single-file pedestrian flow at high densities. Since pedestrians could only follow preceding person in flow, way which chooses their destination changed. It set as current position of pedestrian, rather than one fixed location. order possible movement densities, distance for calculating forces between was reset, and ob...

A mathematical model for blood flow in narrow capillaries under the effect of transverse magnetic field has been investigated. It is assumed that there is a lubricating layer between red blood cells and tube wall. The transient flow of the fit red blood cell surrounded by plasma annulus in the narrow capillary is considered. The analysis of fluid flow between red cell and tube wall, when the ce...
