有限自动机的确定化算法子集法问题探析

子集法是目前普遍采用的确定4LNFA为DFA的方法,但在子集法存在两处疑难：一是NFAM的状态子集I的a弧转换集合Ia的定义与解释;二是确定化过程中先对NFA做改造的必要性以及条件。     

Association of CETP and LIPC Gene Polymorphisms with HDL and LDL Sub-fraction Levels in a Group of Indian Subjects: A Cross-Sectional Study

There is an increasing interest to understand the molecular basis of high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) subfractions and their association with coronary artery disease (CAD). The formation of these subfractions is greatly influenced by hepatic lipase (HL) and cholesteryl ester transfer protein (CETP) enzymes. To identify genetic markers influencing LDL and HDL subfractions and their role in CAD we performed a case–control genetic association study on 117 healthy controls and 119 angiographically verified CAD patients. Biochemical analysis was performed using standard assays. HDL-C and LDL-C subfractions were estimated using precipitation methods. Genotyping of C-514T (rs1800588) in the LIPC gene for HL and I405V (rs5882) in the CETP gene was done using PCR-based restriction enzyme analysis and sequencing. Both the polymorphisms were not associated with CAD. The C-514T was associated with increased HDL₃-C levels in controls (P = 0.049). The I405V polymorphism was found to be associated with low levels of small dense, LDL (P = 0.038). A multiple regression analysis showed that the effects were dependent on gender and triglyceride levels. We conclude that these polymorphisms are not associated with CAD but are important determinants of HDL-C and small dense LDL particles in our population.

广义GHZ态实现的可控密集编码

提出了一种利用广义GHZ态实现的可控密集编码方案。在该方案中,首先控制者Cliff对他所持的粒子进行Von Neumann测量,然后将结果告知Alice和Bob,Alice在引入辅助粒子和实施幺正操作后接着对辅助粒子进行Von Neumann测量,再将测量结果告诉Bob,Bob通过Bell基测量便可辨别出Alice实施的幺正操作,从而以一定的几率得到Alice传送给他的信息。
