摘要：The central solenoid(CS) is an important component of China Fusion Engineering Test Reactor, for producing, forming and stabilizing plasma in the superconducting tokamak. It is a complicated work to design and manufacture the large superconducting CS magnet, so it is meaningful to design a central solenoid model coil(CSMC) and analyze its electromagnetic properties in advance. In this paper, the structure, design parameters and magnetic field distribution of the CS model coil are discussed. The peak power of radial and axial turn conductors and time bucket loss are analyzed by using piecewise-linear method. The CSMC AC loss with different Nb3 Sn CICCs and AC loss of ITER CS coil are compared. The special electrometric method to measure AC loss of the CS model coil for future reference is presented.

摘要：We suggest a design method of graded-refractive-index （GRIN） antireflection （AR） coating for s-polarized or p- polarized light at off-normal incidence. The spectrum characteristic of the designed antireflection coating with a quintic effective refractive-index profile for a given state of polarization has been discussed. In addition, the genetic algorithm was used to optimize the refractive index profile of the GRIN antireflection for reducing the mean reflectance of s- and p-polarizations. The average reflectance loss was reduced to only 0.04% by applying optimized GRIN AR coatings onto BK7 glass over the wavelength range from 400 to 800 nm at the incident angle of θo = 70°.

摘要：4,5-Dihydro-3-methylbenzo[1,2-b]furan-4,5-dione（4） was identified as a novel and potent inhibitor of caspase-3 through structural modification of an existing drug, sodium tanshinone IIA sulfonate（STS）. Compound 4 showed high potency against caspase-3 in vitro（ICso=0. 13μmol/L）. Molecular docking study further provided an insight into the interaction of compound 4 with activated caspase-3. Hence, this small-molecule caspase-3 inhibitor could be a oromising theraoeutic candidate against diseases caused by abnormally up-regulated apptosis.

摘要：过滤算法设计是信息内容安全处理系统中的一个重要环节,过滤速度成为衡量过滤系统性能的首要因素.索引结构是处理大规模数据的一种有效方式,但目前索引方法都是针对特定检索领域而设计,在实际过滤应用中,并不能满足过滤实时性需求.为了加快信息过滤中数据查询的判定速度,文中提出一种基于最小圆覆盖的区域划分方法,构建了适合过滤的索引结构:F-tree.该算法充分考虑实际过滤环境中正例(正常信息)多、反例(敏感信息)少的非平衡数据分布特性,利用最小圆覆盖划分方法得到最大否定判断区域.在查询阶段,正例以最大概率落入否定区域,根据否定性判定原理可以对正例快速否定判定,从而加快整体查询的判定速度.实验表明,与现有算法相比,所提出的算法减少了查询中的距离计算次数,有效提高了过滤查询性能.

摘要：针对现有可信中继QKD(Quantum Key Distribution)网络路由方案应用于广域环境时存在着密钥交换效率低、密钥资源无意义消耗大的问题,分析了影响密钥交换效率的因素,设计了适应广域QKD网络的分层路由方案.该方案将QKD网络划分为若干路由域,并通过拓扑聚合构建分层QKD网络,设计了基于最低层网络匹配的跨域密钥路由算法,使得高层路由域内一跳便可跨过多个低层路由域,极大地降低了密钥中继跳数,提高了密钥交换效率及密钥资源利用率.仿真结果表明分层路由方案相对于现有单层逐跳式路由方案能够提高大约77.6%密钥资源利用率,同时缩短一半密钥服务延时.
