We have demonstrated that tubulin-GTP subunits can react with microtubule ends containing subunits with E-site-bound GDP. This observation can be taken to rule out a previous interpretation of a biphasic dependence of the rate for subunit flux into microtubules on the subunit concentration, which is based upon an assumption that GTP is required to be present in subunits at microtubule ends in o...

A novel computational fluid dynamics and molecular kinetic theory (CFD-MK) method was developed to simulate the impingement of a nanodroplet onto a solid surface. A numerical solution of the Navier–Stokes equation using a volume-of-fluid (VOF) technique was used to model nanodroplet deformation. Dynamic contact angle during droplet impact was obtained by molecular kinetic theory. This dynamic c...

The affinity label 5'-p-(fluorosulfonyl)benzoyl adenosine modifies rabbit muscle phosphofructokinase to the extent of one group/subunit. Modification appears to occur at a binding site specific for AMP, cyclic AMP, and ADP, i.e. those adenine nucleotides which are activators under conditions where regulatory kinetic behavior is obtained. The consequences of the modification are consistent with ...

The effects of oblique incidence on the surface roughness in low-temperature Cu /Cu 100 epitaxial growth are investigated via kinetic Monte Carlo simulations, which include the effects of shadowing as well as short-range and long-range attraction. While the effects of deposition angle are found to be relatively weak at 200 K, at a slightly lower temperature 160 K both the surface roughness and ...
