– We discuss the stretching of tethered chains subject to a shear flow. Fluorescence microscopy measurements of the extension of sheared tethered DNA, “model polymers”, of various lengths are presented. The tethered chains approach full extension as the flow rate is increased, but very slowly. We show that a general theory to understand the large deformation of any sheared tethered chain must i...

This article proposes two approaches to tool-supported automatic verification of dense real-time systems against scenario-based requirements, where a system is modeled as a network of timed automata (TAs) or as a set of driving live sequence charts (LSCs), and a requirement is specified as a separate monitored LSC chart. We make timed extensions to a kernel subset of the LSC language and define...

growth chart is the best measure for weight monitoring of children. most factors that affect child heath show their effect on child weight. this cross sectional and descriptive analytical study was achieved to estimate malnutrition prevalence and effective factors in children under 5 years old in rural area of khoramabad province. 555 girls and 570 boys were chosen from health houses by cluster...

There is a desire to accurately simulate the transient behavior of such passively magnetically stabilized spacecraft both during the initial post separation phase and when subjected to disturbances during the mission. Initial post separation tumbling rates can be of the order of several degrees a second requiring integration time steps of less than a second to preserve numerical accuracy. As sp...

Simulating electron spin resonance spectra of nitroxide spin labels from motional models is necessary for the quantitative analysis of experimental spectra. We present a framework for modeling the spin label dynamics by using trajectories such as those from molecular dynamics (MD) simulations combined with stochastic treatment of the global protein tumbling. This is achieved in the time domain ...
