One of reasons that researchers in recent years have tried to produce ultrafine grained materials is producing lightweight components with high strength and reliability. There are disparate methods for production of ultra-fine grain materials,one of which is severe plastic deformation method. Severe plastic deformation method comprises different processes, one of which is Parallel tubular chann...

The human cytochrome P450 3A4 mono-oxygenates approximately 50% of all drugs. Its substrates/products enter/leave the active site by access/exit channels. Here, we perform steered molecular dynamics simulations, pulling the products temazepam and testosterone-6betaOH out of the P450 3A4 enzyme in order to identify the preferred substrate/product pathways and their gating mechanism. We locate si...

Embryonic lumbar spinal motoneurons (MNs) are characterized by a period of programmed cell death (PCD) that spans several days and occurs in a rostrocaudal gradient. The generation of these MNs also takes place in a temporal-spatial gradient, such that MNs within rostral lumbar segments exit the cell cycle earlier and MNs within progressively caudal regions are born later. In vitro studies have...

unter den verschiedenen bereichen der komparatistik begegnet man einer der in letzten jahren entstandenen disziplinen, die sich gezielt und orientiert bezüglich der historischen und kulturellen quellen versucht, die literarischen relationen zwischen den verschiedenen sprachen durch analyse der fremden episoden zu erl?utern. die imagologie ist ein zwischenkulturelles wissen, das den anderen wiss...

We consider the problem of transmitting a correlated Gaussian source over an AWGN channel. This paper contains two main contributions which aid in the design of such a system. We determine the characteristic curves of the source decoder for use in the extrinsic information transfer charts (EXIT charts) and show how the characteristic curves vary with the amount of correlation in the source. Fur...

Floating emissive probe plasma potential maps of the X2 dual nested channel Hall thruster across a triad of operating conditions (inner, outer, and dual channel) at 150 V discharge voltage are presented. The maps extend from the thruster exit plane and thruster centerline to 3.5 mean outer channel radii (OCR) axially and 2.8 OCR radially. Together with measured floating potential maps, electron...

  Yrast states in mirror nuclei 55Co and 55Ni have been populated with a radioactive ion beam using the Isotope Separator On-Line method. A shielded array of 7 Compton suppressed germanium detectors recorded reaction gamma-rays. For channel selection, an array of 128 independent silicon detectors was used to differentiate exit channels with different number of proton and alpha particles emitted...

Currents flowing through single dihydropyridine-sensitive Ca2+ channels were recorded from cell-attached patches on C2 myotubes. In the presence of dihydropyridine agonist to prolong the duration of single-channel openings, adding micromolar concentrations of lanthanum (La), cerium (Ce), neodymium (Nd), gadolinium (Gd), dysprosium (Dy), or ytterbium (Yb) to patch electrodes containing 110 mM Ba...
