Two analyses, cubic and piecewise random regression, were conducted to model growth of crossbred cattle from birth to about two years of age, investigating the ability of a piecewise procedure to fit growth traits without the complications of the cubic model. During a four-year period (1994-1997) of the Australian "Southern Crossbreeding Project", mature Hereford cows (N = 581) were mated ...

Slip activity in body-centered cubic chromium is modeled by means of ab initio calculation screw dislocations core properties and Peierls potential. As having 1/2<111> Burgers vector also <100>, both gliding {110} crystallographic planes have been reported experimentally, are modeled. A generalized yield criterion incorporating physical ingredients necessary to account for deviations from the S...

We report an ab initio study of the effect of hydrostatic pressure and uniaxial strain on electronic properties of KNa2Bi, a cubic bialkali bismuthide. It is found that this zero-gap semimetal with an inverted band structure at the Brillouin zone center can be driven into various topological phases under proper external pressure. We show that upon hydrostatic compression KNa2Bi turns into a tri...

Helmholtz-Center DresdenRossendorf, Institute of Radiopharmaceutical Cancer Research, PET Center, Dresden, Germany Recently, we have proposed a method for on-the-fly system matrix computation where the tube-of-response (TOR) is approximated as a cylinder with constant density (TORCD) and the cubic voxels are replaced by spheres. We could show that with this model the PET image quality can be no...

Hydrogen embrittlement is a classical problem in bulk materials while it rather untouched for advanced such as micro-architectured materials. This can be barrier to industrial adoption of these where hydrogen present popular source energy. In this study, we developed numerical scheme assess the degradation metallic The built on concept elastoplastic homogenization and two theories, i.e. enhance...

Open-porous scaffolds of WE43 Mg alloy with a body-center cubic cell pattern were manufactured by laser powder bed fusion different strut diameters. The geometry the unit cells was adequately reproduced during additive manufacturing and porosity within struts minimized. microstructure modified means thermal solution ageing heat treatments analysed in detail X-ray microtomography, optical, scann...
