Pseudomonas marginalis, capable of utilizing acetonitrile as the sole source of carbon and nitrogen, was isolated from an industrial waste site. P. marginalis metabolized acetonitrile into ammonia and acetate. The minimal inhibitory concentration values of different nitriles and amides for P. marginalis were in the range 5–300 mM. The bacterium was able to(More)
This Letter is concerned with the determination of the transition paths attendant to nanovoid growth in aluminum under hydrostatic tension. The analysis is, therefore, based on energy minimization at 0 K. Aluminum is modeled by the Ercolessi-Adams embedded-atom method, and spurious boundary artifacts are mitigated by the use of the quasicontinuum method.(More)
The concurrent bridging of molecular dynamics and continuum thermodynamics presents a number of challenges, mostly associated with energy transmission and changes in the constitutive description of a material across domain boundaries. In this paper, we propose a framework for simulating coarse dynamic systems in the canonical ensemble using the(More)
The kinetic Monte Carlo (kMC) method is used in many scientific fields in applications involving rare-event transitions. Due to its discrete stochastic nature, efforts to parallelize kMC approaches often produce unbalanced time evolutions requiring complex implementations to ensure correct statistics. In the context of parallel kMC, the sequential update(More)
A bioactive, fluorescent derivative of gonadotropin-releasing hormone, < Glu-His-Trp-Ser-Tyr-D-Lys(N epsilon-tetramethylrhodamine)-Leu-Arg-Pro-Gly-NH2, was prepared. This peptide retained high-affinity binding (apparent dissociation constant, 3 nM) to the receptor for gonadotropin-releasing hormone and was utilized for microscopic visualization and(More)
The subcellular localization of GnRH receptors in weanling rat anterior pituitary and ovarian tissue was determined by radioligand binding in biochemically defined fractions prepared by differential and density centrifugation. Morphological identification of membrane organelles or fragments, visualized by electron microscopy, confirmed the biochemical(More)
