We use direct and stochastic numerical simulations of the magnetohydrodynamic equations to explore the influence of turbulence on the dynamo threshold. In the spirit of the Kraichnan-Kazantsev model, we model the turbulence by a noise, with given amplitude, injection scale and correlation time. The addition of a stochastic noise to the mean velocity significantly alters the dynamo threshold. Wh...

Abstract This paper presents an improved ray casting algorithm, in order to solve the problems of powerful computing capacity and slow rendering velocity. In the course of ray casting volume rendering, an algorithm of ICT slice images original data field 2D maximum entropy threshold segmentation prior preprocessing is proposed. It is used to define the extent of threshold, and research the opti...

Understanding the collisional outcomes of dust aggregates and dependence on material properties constituting particles is great importance toward understanding planet formation. Recent numerical simulations have revealed that interparticle tangential friction plays a crucial role in energy dissipation during collisions between porous aggregates; however, growth remains poorly understood. Here w...

In this study, the relationship between a person’s walking speed and perception threshold for discrete implicit repositioning during eyeblinks in virtual environment is investigated. The aim to estimate thresholds forward backward translation following eyeblink occurrences. A psychophysical method called Staircase Transformed Weighted up/down utilized quantify repositioning. are estimated three...

objective: the aim of present study was to evaluate the effects of oral administration of gallic acid (ga) for 21 days alone and in combination with exercise on nerve conduction velocity and sensory and motor functions in rats with sciatic nerve crush. materials and methods: seventy adult male wistar rats (250-300 g) were divided randomly into 7 groups with 10 in each: 1) control (cont), 2) cru...

24 Rate of torque development and the subsequent movement velocity are modulated by 25 motor unit (MU) properties, primarily MU discharge rate and MU recruitment threshold 26 (MURT). In isometric conditions, MURTs have been shown to decrease with increased rates of 27 torque development. It is unclear whether this relationship is similar in the production of 28 dynamic shortening contractions. ...
