In order to gain a better understanding of how to prevent sparks creeping along dielectric surfaces the most common cause of failure in high voltage devices we have studied the propagation of the preceding streamers along dielectric surfaces. We applied a voltage pulse to a needle a small distance above a dielectric sample a thin vertically positioned plate in low-pressure air, and imaged the r...

A time-free, drift-free, multi-dimensional model of friction is introduced. A discrete implementation is developed which exhibits four solution regimes: sticking, creeping, oscillating, and sliding. Its computational solution is efficient to compute online and is robust to noise. It is applied to haptic rendering.

MicroRNA528 (miR528) is a conserved monocot-specific small RNA that has the potential of mediating multiple stress responses. So far, however, experimental functional studies of miR528 are lacking. Here, we report that overexpression of the rice (Oryza sativa) miR528 (Osa-miR528) in transgenic creeping bentgrass (Agrostis stolonifera L.)

Myiasis is the condition or conditions resulting from the invasion of the tissues and organs of man and other animals by the eggs or larvae of dipterous flies. Such invasion may be simple, i.e. without any severe constitutional disturbances, or may result in violent disturbances causing even death. According to the site of invasion one may have cutaneous, dermal, intestinal, urinary, nasal, ora...

aim and background: insecure attachment style is one of the important effective factors in many mental disorders. the aim of this study was to compare the positive, negative and disorganized schizotypal characteristics in secure, avoidance and anxiety attachment patterns among students of tabriz university, iran. methods and materials: in this cross-sectional descriptive study 300 students (150...

This work is focused on the application of high order traffic flow theory to the problem of traffic incident detection, and for modeling multiclass traffic flow composed of different vehicle types. For incident detection applications, a class of generic second order traffic flow models (GOSM) is applied to detect traffic incidents in real time by posing the problem as a hybrid state estimation ...

In 1998, researchers at the University of Maryland discovered a new disease of creeping bentgrass caused by an unidentified species of Ophiosphaerella. Through morphological and molecular study, it was shown that the pathogen constituted a new species, Ophiosphaerella agrostis, and the disease was named bentgrass dead spot. Subsequently, O. agrostis was found in Texas and Florida causing dead s...

[1] Sequences of earthquakes are commonly represented as a succession of periods of interseismic stress accumulation followed by coseismic and postseismic phases of stress release. Because the recurrence time of large earthquakes is often greater than the available span of space geodetic data, it has been challenging to monitor the evolution of interseismic loading in its entire duration. Here ...
