Numerous experiments have been conducted on plunging Eppler 361 airfoil in a subsonic wind tunnel. The experimental tests involved measuring the surface pressure distribution over the airfoil at Re=1.5×105. The airfoil was equipped with Gurney flap(heights of 2.6, 3.3 and 5% chord) and plunged at 6cm amplitude. The unsteady aerodynamic loads were calculated from the surface pressure measurement...

rho-kinase is an effector molecule of rhoa, a monomeric gtp-binding protein, and causes ca2+ sensitization through inactivation of myosin phosphatase. the major physiological functions of rho/rho-kinase cascade include contraction, proliferation and migration in cells.there are some excellent reviews about rho/rho-kinase signal pathway, most of which focus on the specific proteins of the pathwa...

We investigate the effect of a large number of kinks on the gravitational power radiated by cosmic string loops. We show that the total power radiated by a loop with N left-moving and right-moving kinks is proportional to N and increases with the typical kink angle. We then apply these results to loops containing junctions which give rise to a proliferation of the number of sharp kinks. We show...

During replication initiation, the core component of the helicase-the Mcm2-7 hexamer-is loaded on origin DNA as a double hexamer (DH). The two ring-shaped hexamers are staggered, leading to a kinked axial channel. How the origin DNA interacts with the axial channel is not understood, but the interaction could provide key insights into Mcm2-7 function and regulation. Here, we report the cryo-EM ...

In 1945, Rosenbaum and his associates proposed that ventricular pre-excitation should be classified into two types (A and B) according to the configuration of the QRS complexes in the right precordial leads of the scalar electrocardiogram. In type A pre-excitation the delta wave is positive and the S waves are small or absent; in type B the delta wave is negative and the S waves are large. Thou...

A modification of the vectorcardiographic method of studying electrical events is presented. Simultaneous scalar leads, taken by any vector lead system, are first recorded. The important time intervals, difficult or impossible to read from the loop itself, are measured from these tracings. Proper pairs of the scalar leads can then be rapidly integrated into vector loops by an easily constructed...

Pijushpani Bhattacharjee, Narendra Sahu, and Urjit A. Yajnik Department of Physics, Indian Institute of Technology, Bombay, Mumbai 400076, India and Indian Institute of Astrophysics, Bangalore-560 034, India Abstract Cosmic strings arising from breaking of the U(1)B−L gauge symmetry that occurs in a wide variety of unified models can carry zero modes of heavy Majorana neutrinos. Decaying and/or...
