starting from the results of charles fefferman and janos koll \ ' ar in \ texit { continuous solutions of linear equations } [ 1 ], we adopt a new approach based on fefferman ' s techniques of glaeser refinement to show a more general result than the one proved by koll \ ' ar by using techniques from algebraic geometry... | arxiv:2202.05815 |
we investigate here the fast electron scattering upon endohedral atoms that present a fullerene cn staffed by an atom a, a @ cn. we calculate the inelastic scattering cross - section expressing it via generalized oscillator strengths ( gos ) density. we take into account two major effects of cn upon ionization of the a... | arxiv:1203.0649 |
the cms experiment has been designed with a two - level trigger system : the level 1 ( l1 ) trigger, implemented on custom - designed electronics, and the high level trigger ( hlt ), a streamlined version of the cms reconstruction and analysis software running on a computer farm. in order to achieve a good rate reducti... | arxiv:1409.4077 |
since the development of the beowulf project to build a parallel computer from commodity pc components, there have been many such clusters built. the milc qcd code has been run on a variety of clusters and supercomputers. key design features are identified, and the cost effectiveness of clusters and supercomputers are ... | arxiv:hep-lat/0011071 |
we analyze the impact of using $ b $ - tagged samples in studying non - abelian effects due to qcd in $ e ^ + e ^ - \ ar 4 $ jet events at $ \ sqrt s = m _ { z ^ 0 } $, using angular variable analyses and comparisons with $ e ^ + e ^ - \ ar 3 \ mbox { jet } \ gamma $ events. we find that qcd effects are largely enhance... | arxiv:hep-ph/9503354 |
