Previous theoretical simulation and experimental studies have indicated that particles with a short-ranged attraction exhibit a range of dynamical arrest phenomena. These include very pronounced reentrance in the dynamical arrest curve, a logarithmic singu ...
Using a first-principles approach, we compare calculated core-level shifts with experimental data for amorphous carbon at different densities. We used a molecular dynamics approach based on an environmental-dependent tight-binding (EDTB) Hamiltonian to gen ...
A molecular dynamics simulation of 4, 4'-dichlorobiphenyl sulfone was carried out in order to study the phase transition from a normal to incommensurate modulated phase observed experimentally. Agreements of simulated and experimental diffraction patterns ...
The past five years have led to a tremendous increase in our molecular understanding of the mode of action of the anthrax toxin, one of the two main virulence factors produced by Bacillus anthracis. The structures of each of the three components of the tox ...
To investigate the mechanism of structural changes of a peptide nanotube and water confined inside the channel, the helical peptide tryptophylglycine monohydrate (WG-H2O) was studied by molecular dynamics (MD) simulations using the three-dimension parallel ...
The reaction of [(dropSiO)Zr(CH(2)tBu)(3)] with H-2 at 150 degreesC leads to the hydrogenolysis of the zirconium-carbon bonds to form a very reactive hydride intermediate(s), which further reacts with the surrounding siloxane ligands present at the surface ...
Motor proteins and microtubule-associated proteins (MAPs) play important roles in cellular transport, regulation of shape and polarity of cells. While motor proteins generate motility, MAPs are thought to stabilize the microtubule tracks. However, the prot ...
We have investigated the role of cytoplasmic dynein in microtubule organizing center (MTOC) positioning using RNA-mediated interference (RNAi) in Caenorhabditis elegans to deplete the product of the dynein heavy chain gene dhc-1. Analysis with time-lapse d ...
Lon (or La) is a soluble, homooligomeric ATP-dependent protease. Mass determination and cryoelectron microscopy of pure mitochondrial Lon from Saccharomyces cerevisiae identify Lon as a flexible ring-shaped heptamer. In the presence of ATP or 5'-adenylylim ...

The feasibility of spectral editing techniques making use of heteronuclear scalar couplings in solid-state CPMAS NMR is demonstrated for powder samples exhibiting line widths of several tens of hertz such as ordinary amino acids. These simple and robust ex ...
