Every animal cell is filled with a cytoskeleton, dynamic gel made of inextensible fibers, such as microtubules, actin and intermediate filaments, all suspended in viscous fluid. Numerical simulation this challenging because the fiber aspect ratios can be large $10^4$. We describe new method for rapidly computing dynamics slender filaments periodically-sheared Stokes flow. The are governed by no...

Abstract The mitotic spindle is a highly dynamic bipolar structure that emerges from the self-organization of microtubules, molecular motors and other proteins. Sustained motor-driven poleward flows microtubules play key role in organization spindles. However, it not understood how local activity motor proteins generates these large-scale coherent flows. Here we show gelation transition enables...

In two-stage cluster surveys, the traditional method used in second-stage sampling (in which the first household in a cluster is selected) is time-consuming and may result in biased estimates of the indicator of interest. Firstly, a random direction from the center of the cluster is selected, usually by spinning a pen. The houses along that direction are then counted out to the boundary of the ...

PURPOSE Results of the MENTORED QUALITY IMPROVEMENT IMPACT PROGRAM℠ (MQIIP) on Ensuring Insulin Pen Safety in Hospitals, which was part of an ASHP educational initiative aimed at ensuring the safe use of insulin pens in hospitals, are described. METHODS During this ASHP initiative, which also included continuing-education activities and Web-based resources, distance mentoring by pharmacists w...

where GK is the pluricomplex Green’s function of K with pole at infinity, d = ∂ + ∂̄, and d = (i/2π)(∂̄ − ∂). The support of μK is contained in the Shilov boundary of K. When n = 1, the measure μK is simply harmonic measure for the domain C − K evaluated at infinity. See Section 2. Let F : C → C be a regular polynomial endomorphism; that is, one which extends holomorphically to CP. The filled Jul...
