Recently, Kumari et al. pointed out that Chang et al.’s scheme “Untraceable dynamic-identity-based remote user authentication scheme with verifiable password update” not only has several drawbacks, but also does not provide any session key agreement. Hence, they proposed an improved remote user authentication Scheme with key agreement on Chang et al.’s Scheme. After cryptanalysis, they confirm ...

Colonic mucosal lymphoid cells, selectively enriched for intraepithelial (IEL) or lamina proprial lymphocytes (LPL), were isolated by sequential EDTA-collagenase treatment of resected human colons. Cytotoxic activities of colonic and peripheral blood lymphoid cells (PBL) were tested in three different assays, using chicken erythrocytes (CRBC) and Chang cells as targets. Antibody-dependent cell-...

In 2000, Lee and Chang proposed a user identification scheme with key distribution preserving anonymity for distributed computer networks. Recently, Wu and Hsu pointed out that there are two weaknesses in the LeeChang scheme. They further not only proposed a new scheme to remedy the security leaks of the Lee-Chang scheme, but also reduced computation complexities and communication cost as compa...

The hepatitis B virus X (HBX) protein, a regulatory protein of the hepatitis B virus (HBV), has been shown to generate reactive oxygen species (ROS) in human liver cell lines; however, the mechanism by which cells protect themselves under this oxidative stress is poorly understood. Here, we show that HBX induces the up-regulation of Forkhead box class O 4 (Foxo4) not only in Chang cells stably ...

Relaxed technique is one of techniques for improving convergence rate of splitting iterative methods. Based on local relaxed method and system relaxed method of parallel multisplitting Frommer andMayer [A. Frommer, G. Mayer, Convergence of relaxed parallel multisplitting methods, Linear Algebra Appl. 119 (1989) 141–152], we give the global relaxed parallel multisplitting (GRPM) method by introd...

lots of papers has been written about iran’s military strategy explain military strategy of iran is deterrence, but there is a little paper that explain why iran chose this strategy? the paper tries to answer this question. two hypotheses are presented as probable answers to the question: 1-chang of balance power in the middle east 2- intensification of u.s pressure on iran for regime change.lo...

In this paper, we discuss a paper of Chang and Teng [C.T. Chang, J.T. Teng, Retailer’s optimal ordering policy under supplier 4 credits, Mathematical Methods of Operations Research 60 (2004) 471–483], they established an inventory model for deteriorating 5 items when the supplier permits not only a cash discount but also a permissible delay. They also proved a closed-form solution 6 of the inve...

Using data from a randomized controlled trial involving door-to-door HIV education, homebased voluntary HIV counseling and testing (VCT), and facility-based VCT, the latter of which relies on conditional cash transfers, we find that both home-based VCT and facility-based VCT significantly increase HIV testing take-up, with the former being more effective in detecting HIV-positive cases. We also...

We develop a method for interpolating scattered data on sphere-like surfaces based on a local triangular patch which is constructed from a blend of certain spherical Bernstein-B ezier polynomials introduced recently by Alfeld, Neamtu & Schumaker 2]. The method produces a C 1 interpolant which matches values and derivatives, and is a natural analog of a planar method of Foley & Opitz 6] and Good...
