The mosaic structure in a Ni-based single-crystal superalloy is simulated by molecular dynamics using a potential employed in a modified analytic embedded atom
“这里是 Radio Beijing(注:中国国际广播电台的呼号‘北京电台’),中国十亿人民的心声……”一阵阵悠扬的乐曲声,从民族文化宫二楼东展厅中飘出,吸引着成百上千的观众。国
In this study, the Reynolds-averaged Navier Stokes (RANS) method is employed to simulate the flow within and over an intersection model with three kinds of κ-
Many new forms of Boussinesq-type equations have been developed to extend the range of applicability of the classical Boussinesq equations to deeper water in th
The problem of making a stable Takagi-Sugeno (TS) fuzzy system chaoticby using the state feedback control of arbitrarily small magnitude is studied. The feedbac

Based on entanglement swapping, a scheme for the secret sharing of an arbitrary two-particle entangled state is proposed. If the controllers do not co-operate w
The dynamics of coupled Lorenz circuits is investigated experimentally. The partial amplitude death reported in Phys. Rev. E 72, 057201 (2005) is verified by ph
<正> “美国之音”高级科学编辑及科学记者拉索罗·多萨会见一位专家时,把他的叙述当作可能会引起“美国之音”听众的一次考试。“正像大多数听众一样,我并无任何科学经历”,他说。“所以我提出使我感兴趣的问题,并期望也能引起听众的兴趣。”多萨于1929年生于匈牙利的塞格德,并于1955年前来到“美国之音”任职。起初,他在“美国之音”的匈牙利部任节目制作人、撰稿人、播音员及采编,前后达十年之久。那些年,他也开始用英语写播音稿,并希望突破用一种语言播音的限制。
In this paper, we study the Hawking radiation via tunnelling from a uniformly accelerating black hole. Although the Bekenstein-Hawking entropy is proportional a
