In order to integrate new security protocols, existing systems must be modified accordingly, which often means interrupting system activity. We propose a solution to this problem by developing an ontology model which provides semantic to security protocol operations. The proposed model is based on a formal specification model and is integrated in existing Web service description technologies.

This study points out that a malicious communicant in Hwang et al.’s probabilistic quantum key distribution (PQKD) protocol can manipulate the secret key without being detected by using the unitary operation attack. Accordingly, the security requirements of a PQKD protocol, i.e., unpredictability and fairness, cannot be satisfied in their protocol. A possible solution is also provided to solve ...

We present in this paper recent progress in Sanskrit computational linguistics. We propose a solution to the tagging of verb phrases which correctly handles the non-associativity of external sandhi arising from the treatment of preverb ā. This involves a notion of phantom phoneme. We give exemples of execution of a computer tagger designed accordingly, which handles verb phrases as well as noun...

Naphthyl Red moiety, conjugated to DNA, shows distinct chromism by hybridization with its complementary DNA. Single-stranded DNA involving Naphthyl Red moiety exhibits orange color and has lambda max at 466 nm at pH 7.0. Absorption maximum shifts towards 545 nm by the presence of its complementary DNA, and accordingly color of the solution changes from orange to magenta.

results a total number of 43 specimens were studied, from which 9 were obtained from patients with metastatic prostate cancer. the expression of five examined genes had no correlation with psa level and gleason score. the expression of amacr decreased in metastatic prostate cancer (p = 0.02). the expression of other genes showed no difference between metastatic and non-metastatic tumors (p > 0....

Objective: Reducing white adipose tissue is an important strategy for treatment of obesity and its related metabolic disorders. The purpose of this study was to determine the effect of endurance exercise and adenosine consumption on the expression of selected genes of thermogenic pathway in the visceral adipose tissue of obese male rats. Materials and Methods: Twenty male wistar rats were fed ...

conclusions application of zinc oxide as the photocatalyst can be effective in the removal process. background one of the important achievements of the past decade was the rapid growth of industries and accordingly production of various chemical compounds. objectives this study presents a combined system of photocatalytic oxidation and absorption solution to remove nitrogen oxides from polluted...

Abstract We study the excitation of fluting perturbations in a magnetic tube by an initially imposed kink mode. use ideal magnetohydrodynamic (MHD) equations cold-plasma approximation. also thin-tube approximation and scale dependent independent variables accordingly. Then we assume that dimensionless amplitude mode is small it as expansion parameter regular perturbation method. obtain expressi...

In normal colon, claudin-2 expression is restricted to the crypt bottom containing the undifferentiated and proliferative colonocytes. Claudin-2 expression is also upregulated in colorectal cancer (CRC) and promotes carcinogenesis. However, cellular mechanism/s regulated by increased claudin-2 expression during the CRC and mechanism/s regulating this increase remain poorly understood. Epigeneti...
