Kinesin and dynein are fundamental components of intracellular transport, but their interactions when simultaneously present on cargos are unknown. We built an optical trap that can be calibrated in vivo during data acquisition for each individual cargo to measure forces in living cells. Comparing directional stall forces in vivo and in vitro, we found evidence that cytoplasmic dynein is active...

A SMT processor can fetch and issue instructions from multiple independent hardware threads at every CPU cycle. Therefore, hardware resources are shared among the concurrently-running threads at a very fine grain level, which can increase the utilization of processor pipeline. However, the concurrently-running threads in a SMT processor may interfere with each other and stall the CPU pipeline. ...

Active controllers that allow the compressor to operate safely at its peak pressure rise point by preventing surge and controlling entry into rotating stall need to be globally stabilizing. Bifurcation methods have emerged as a useful tool for the analysis of global stability and control of nonlinear dynamical systems such as the axial compressor. In this paper we show how bifurcation analysis ...

Surfing is a popular sport, with the associated market forecast to reach 2.6 billion US dollars by 2027. In published literature, there range of investigations into performance surfboard fins. Some studies model single fin or review different layouts and surface designs. However, effects individual design features on flow dynamics are not well understood. This study provides numerical analysis ...

Abstract. Monitoring the flow features over wind turbine blades is a challenging task that has become more and crucial. This paper devoted to demonstrate ability of e-TellTale sensor detect stall–reattachment dynamics blades. made strip with strain gauge at its base. The velocity field was acquired using time-resolved particle image velocimetry (TR-PIV) measurements an oscillating 2D blade sect...

Flexible aerodynamic surfaces have been shown to favorably influence flight characteristics by increasing lift, angle of attack at stall, and resistance to perturbation. The objective of the research presented within this thesis is to investigate the influence of two aspects of flight observed in biological flyers, a suction-surface flap and dynamic stall, when applied to pliant wings. A rigid ...
