Let {An}∞n=0 be an arbitary sequence of natural numbers. We say A（n,k;A） are the Convolution Annihilation Coefficients for {An}n∞=0 if and only if n∑κ=0A（n,k;A）（x-Aκ）n-k=xn. （0.1） Similary, we define B（n,k;A） to be the Dot Product Annihilation Coefficients for {An}n∞=0 if and only if n∑κ=0A（n,k;A）（x-Aκ）n-k=xn. （0.2） The main result of this paper is an explicit formula for B（n,k;A）, which depends on both k and {An}∞n=0. This paper also discusses binomial and q-analogs of Equations （0.1） and （0.2）.

MONTE CARLO NEUTRINO EVENT GENERATORS

引用

Chinese Physics C 2016年第10期40卷 550-552页

作者： h. Gallagher Y. hayato Tufts U. Tokyo U.

Monte Carlo neutrino generators are programs or libraries which simulate neutrino interactions with electrons, nucleons and nuclei. In this capacity their usual task is to take an input neutrino and nucleus and produce a set of 4-vectors for particles emerging from the interaction, which are then input to full detector simulations. Since these generators have to simulate not only the initial interaction of neutrinos with target particles, but re-interactions of the generated particles in the nucleus, they contain a wide range of elementary particle and nuclear physics. Viewed more broadly, they are the access point for neutrino experimentalists to the theory inputs needed for analysis. Examples include cross section libraries for event rate calculations and parameter uncertainties and reweighting tools for systematic error evaluation.

引用

Acta Metallurgica Sinica(English Letters) 1996年第6期9卷 509-514页

The carbide growth behavior of MAR-M247 LC alloy was investigated by directional solidification and quench method. The carbide volume fraction, trapping and growth behavior were correlated with the growth *** was found that the carbide volume fraction decreased at slower growth *** decreasing was caused by lower solidliquid interface trapping ability at slower growth rate.

Differential and total cross sections of the γp→π0p and the γd→π0pn reaction were measured for photon energies between 640 and 1 150 MeV. The data have been compared with SAID and MAID model calculations. π0 photoproduction on the deuteron shows a strong suppression of the 2nd resonance which is clearly seen in the γp→π0p reaction.

Microstructure characterization and effect of extrusion temperature on biodegradation behavior of Mg-5Zn-1Y-xCa alloy

引用

Transactions of Nonferrous Metals Society of China 2018年第11期28卷 2200-2214页

作者： F.DOOST MOhAMMADI h.JAFARI Materials Engineering Department Faculty of Materials Engineering and Modern TechnologiesShahid Rajaee Teacher Training University16785-136 TehranIran

Microstructure and biodegradation behavior of as-cast and hot extruded Mg-5Zn-1Y alloy containing different amountsof calcium （0.0%, 0.1%, 0.5%, and 1.0%, mass fraction） were explored. The extrusion process was conducted at three differenttemperatures of 300, 330, and 370 ℃. Chemical composition, phase constitution, microstructure, and biodegradation behavior of thealloys were investigated. The macro- and micro-scopic examination revealed that the addition of Ca refines the grain structure andforms an intermetallic phase, Ca2Mg6Zn3. The hot extrusion process resulted in breaking the intermetallic phases into fine particlesrouted to the extrusion direction. Moreover, dynamic recrystallization happened in almost all alloys, and more bimodalmicrostructure was formed in the alloys when the alloys were extruded at 370 ℃. Polarization curves showed no passive region,which indicated that active polarization dominated in the alloys; therefore, grain refining through Ca addition and dynamicrecrystallization over hot extrusion operation increased biodegradation rate. The results show that the as-cast Mg-5Zn-1Y-0.1Caalloy provides the highest corrosion resistance, and the extruded Mg-5Zn-1Y-0.5Ca alloy at 300 ℃ shows the lowestbiodegradation rate among the extruded alloys. Therefore, hot extrusion does not always improve the biodegradation behavior ofmagnesium alloys.

Gas–solid interaction force from direct numerical simulation (DNS) of binary systems with extreme diameter ratios

引用

Particuology 2009年第4期7卷 233-237页

作者： S. Sarkar S.h.L. Kriebitzsch M.A. van der hoef J.A.M. Kuipers Department of Science and Technology University of Twente P.O. Box 217 7500 AE Enschede The Netherlands

Fluid-particle systems as commonly encountered in chemical, metallurgical and petroleum industries are mostly polydisperse in nature. however, the relations used to describe fluid-particle interactions are originally derived from monodisperse systems, with ad hoc modifications to account for polydispersity. In previous work it was shown that for bidisperse systems with moderate diameter ratios of 1：2 to 1：4, this approach leads to discrepancies, and a correction factor is needed. In this work we demonstrate that this correction factor also holds for more extreme diameter ratios of 1：5, 1：7 and 1： 10, although the force on the large particles is slightly overestimated when using the correction factor. The main origin of the correction is that the void surrounding the large particles becomes less in case ofa bidisperse mixture, as compared to a monodisperse system with the same volume fraction. We further investigated this discrepancy by calculating the volume per particle by means of Voronoi tessellation.
