Cross-correlated fluctuations of isotropic chem. shifts can provide evidence for slow motions in biomols. Slow side-chain dynamics have been investigated in 15N and 13C enriched ubiquitin by monitoring the relaxation of Ca-Cb two-spin coherences (Frueh et ...
TaSe3 belongs to a class of low-dimensional materials characterized by the interplay and competition between dimensionality crossover and broken symmetry ground states. A comprehensive study by dc-transport, optical, and angle-resolved photoemission (ARPES ...

Parkinson's disease (PD) is a neurologic disorder resulting from the loss of dopaminergic neurons in the brain. Two lines of evidence suggest that the protein alpha-synuclein plays a role in the pathogenesis of PD: Fibrillar alpha-synuclein is a major comp ...
The paper considers the impact of multiple shareholder-oriented governance practices on R&D decisions. Based on a sample of 5,528 firms belonging to 110 large French listed business groups, our results substantiate the idea that shareholder-oriented govern ...
Cytoskeletal rearrangement occurs in a variety of cellular processes and involves a wide spectrum of proteins. Among these, the gelsolin superfamily proteins control actin organization by severing filaments, capping filament ends and nucleating actin assem ...
We have found evidence that water plugs in hydrophilic nanochannels can be at significant negative pressure due to tensile capillary forces. The negative pressure of water plugs in nanochannels induces bending of the thin channel capping layer, which resul ...
Compositional studies of electrode films based on RuO2-TiO2 mixts., prepd. by pyrolytic oxidn. of RuCl3.3H2O-diisopropoxybis(2,4-pentanedionato)titanium deposits show that these materials contain large amts. of carbon and hydrogen impurities. This evidence ...
We present internal-photoemission (photocurrent) experimental evidence for a Fano resonance at an n-p GaAs homojunction with a 0.5-ML Si intralayer (delta doping). This is one of a very few cases in which Fano resonances have been observed in artificial na ...
Vasomotion has been studied on segments of rat mesenteric and femoral arteries perfused in vitro. We have investigated 1) the effect of perfusion flow on the characteristics of vasomotion and 2) the nature and patterns of vasomotion. We have found that per ...
