Observation of the penetration of subbarrier ultracold neutrons through beryllium foils and coatings
V. E. Varlamov V. V. Nesvizhevskii A. P. Serebrov R. R. Tal’daev A. G. Kharitonov P. Geltenbort M. Pendlebury A. V. Strelkov V. N. Shvetsov K. Schreckenbach 《JETP Letters》1997,66(5):336-343
The subbarrier passage of ultracold neutrons through beryllium foils and coatings with a probability much higher than that
of tunneling is observed. This effect may be responsible for the so-called anomalous loss of ultracold neutrons.

The behavior of the peptide corresponding to beta domain of human alpha-lactalbumin (GYDTQAIVENNESTEYG, WT) has been simulated by the molecular dynamics method. It is shown that, within the model considered, the monomer of this peptide does not tend to form a stable secondary structure; however, simulation of the behavior of several peptide molecules revealed the occurrence of beta structures due to the formation of intermolecular hydrogen bonds. Since the aforementioned interactions involve the terminal portions of peptides, the influence of the tetrapeptide corresponding to the N-terminal portion of WT, TDYG (R), on the secondary structure has been analyzed. The model calculations show that the interaction of this peptide with WT monomer facilitates formation of beta-structures. It is suggested that peptide R may affect the quaternary structure of WT. 相似文献

The operation of rapid burst firing multirail electromagnetic launchers of solids is numerically simulated using unsteady two-dimensional and three-dimensional models. In the calculations, the launchers are powered by a Sakhalin pulsed magnetohydrodynamic generator. Launchers with three and five pairs of parallel rails connected in a series electrical circuit are considered. Firing sequences of different numbers of solid projectiles of different masses is modeled. It is established that the heating of the rails is one of the main factors limiting the performance of launchers under such conditions. It is shown that the rate of heating of the rails is determined by the nonuniformity of the current density distribution over the rail cross-section due to the unsteady diffusion of the magnetic field into the rails. Calculations taking into account the unsteady current density distribution in the rails of a multirail launcher show that with an appropriate of the mass of the projectiles (up to 800 g), their number in the sequence, and the material of the rails, it is possible to attain launching velocities of 1.8–2.5 km/s with moderate heating of the rails. 相似文献
