The Arp2/3 complex is a powerful nucleator of actin filaments when activated. A recent study has now revealed that this complex is not only subject to positive control but that there also exists a brake on its activity. This brake can suppress both the basal activity of the Arp2/3 complex as well as its activation by nucleation-promoting factors.

The statistical data published by National Police Agency, Taiwan, indicated that the motorcycle induced the highest accident rate, and drunk driving ranked first among the traffic fatality causes in 2007. The high traffic accident rate was attributed to the alcohol decaying driver reaction and the increase of frequency of using motorcycle in daily life as the car parking space and driving cost ...

In this study, a quasi-realistic thermodynamic analysis was performed to investigate the effects of design and operating parameters on performance single-cylinder modern Atkinson cycle engine. Fortran used for all calculations. It assumed that fuel-air mixture as working fluid, iso-octane fuel. The Wiebe function combustion process it specific heat fluid varies with temperature. calculations, t...

in this paper, the amount of wasted heat from different parts of a 12 liter compression ignition engine and their potential for waste heat recovery were investigated. then, two-stage configuration of organic rankine cycle was introduced for simultaneous heat recovery from exhaust gases and coolant. finally, parameters like hybrid generated power, engine thermal efficiency and brake specific fue...

Intracellular viscosity is a fundamental physical parameter that indicates the functioning of cells. In this work, we developed a simple boron-dipyrromethene (BODIPY)-based probe, BTV, for cellular mitochondria viscosity imaging by coupling a simple BODIPY rotor with a mitochondria-targeting unit. The BTV exhibited a significant fluorescence intensity enhancement of more than 100-fold as the so...

Over the years designers have developed various combined brake-accelerator pedals in an effort to eliminate the operator’s risk of pressing the wrong pedal as well as to reduce his or her reaction time in braking. The goal of this study was to highlight problems that drivers may face when they switch between pedal systems. Eighteen male and female drivers varying in age participated in the stud...
