Astronomers evidence Einstein theories star orbiting massive black hole
2019/10/22
More than 100 years ago, Albert Einstein predicted that light is deflected by extremely massive objects, but there is no way to test such powerful effects on Earth. Instead, astronomers turn their att...
2019年5月7-8日，STAR前向径迹探测器升级及相关物理研讨会（Workshop on STAR Forward Tracking Detector Upgrade and Related Physics）在山东大学青岛校区前沿交叉科学青岛研究院举行。会议由山东大学粒子科学技术研究中心主办。来自美国布鲁克海文国家实验室、石溪大学、伊利诺伊大学芝加哥分校，以及清华大学、北京大学、中国科学技术大学...
On April 25, NSF's Laser Interferometer Gravitational-Wave Observatory (LIGO) and the European-based Virgo detector registered gravitational waves from what appears to be a crash between two neutron s...
pRate: Anonymous Star Rating with Rating Secrecy
reputation management star rating anonymity

We introduce pRate, a novel reputation management scheme with strong security and privacy guarantees for the users and their reputation scores. The reputation scores are computed based on the (aggrega...
近日，位于美国布鲁克海文国家实验的RHIC－STAR国际实验组在Physical Review D上以快速通讯发表了目前最精确的W玻色子单自旋不对称的实验结果（Phys. Rev. D99,051102,2019）。新的实验结果将帮助澄清一个困扰粒子物理领域多年的基本问题：质子的自旋是如何由组成它的夸克和胶子来携带的？发表的新结果首次清晰揭示：质子内众多的海夸克因为味道不同，而对质子自旋的贡献差异...
探讨3D自由呼吸径向采集K空间放射填充容积内插成像（Star VIBE）序列在儿童腹部MR增强检查中的应用价值。方法 对72例患儿采用超快速小角度激发（tfl）梯度回波序列及3D自由呼吸Star VIBE序列进行腹部增强MR扫描，对2种扫描序列得到的增强T1WI进行主观评分，并测量其SNR和CNR，比较2种图像的差异。
猪StAR基因启动子区克隆及其转录活性研究
StAR基因 启动子 荧光素酶活性 报告基因
2018/7/26
旨在通过分析猪StAR基因启动子活性区域，探究猪StAR基因的转录调控机制，从育种学角度为提高猪繁殖力提供新思路。本研究根据Ensembl数据库已公布的猪StAR基因的5'侧翼区序列，利用在线预测软件对该基因启动子区序列信息进行分析，以大白猪基因组DNA为模板，利用特异性引物，进行PCR扩增、测序，进而构建启动子区不同缺失片段的pGL3-StAR双荧光素酶表达载体，转染293T细胞并进行活性检测。...
