Winding and unwinding ATP synthase

ell migration depends on polarized actin polymerization at a cell's front edge. To get the most out of these actin networks, plasma membrane flexibility must be similarly polarized, according to results from Amit Vasanji, Paul Fox (Cleveland Clinic Foundation, Cleveland, OH), and colleagues. The group shows that the membrane is stiffest at the front of migrating endothelial cells. This oriented...

After obtaining a Medical Degree following years of study and the subsequent long and exhausting specialty education program, the tired and now not-so-young doctor has to ship-off to rural areas and practice in a small town in order to gather " Points " compulsory for a Pe...

Winding and Unwinding and Essential Intersections in H

Let G = 〈A,B〉 be a non-elementary two generator subgroup of Isom(H). If G is discrete and free and geometrically finite, its quotient is a pair of pants and in [5] we produced a formula for the number of essential self intersections (ESIs) of any primitive geodesic on the quotient. An ESI is a point where the geodesic has a self-intersection on a seam. Self-intersections of geodesics on arbitra...

Topological winding and unwinding in metastable Bose-Einstein condensates.

Topological winding and unwinding in a quasi-one-dimensional metastable Bose-Einstein condensate are shown to be manipulated by changing the strength of interaction or the frequency of rotation. Exact diagonalization analysis reveals that quasidegenerate states emerge spontaneously near the transition point, allowing a smooth crossover between topologically distinct states. On a mean-field leve...
