background: patient radiation doses from computed tomography (ct) are increasing due to the number of ct examinations performed every day. the aim of this study was assess and evaluate patient radiation doses for adult’s common ct examinations to derive local diagnostic guidance levels for common ct examinations. materials and methods: volume and weighted computed tomography dose index (ctdivol...

conclusions therefore the non-infectious dlps were became infectious if introduced into the cytoplasm of permissive and cancerous cells, without passing attachment and entry process. results we attempt to avoid the attachment and entry of the rotavirus by using lipofectamine to mediate the delivery of viral particles directly into the cytoplasm. dlp was endocytosed into the cytoplasm following ...

The article describes the preparation process of software complex (package) consisting secure corporate chat and DLP (Data Leak Prevention) system in form security monitor. Software development, project architecture, testing other creation stage are demonstrated. operation processes monitor shown; functionality package DLP–system is considered.

Pairing–based cryptosystems are well implemented with Ate–type pairing over Barreto–Naehrig (BN) curve. Then, for instance, their securities depend on the difficulty of Discrete Logarithm Problem (DLP) on the so–denoted G3 over BN curve. This paper, in order to faster solve the DLP, first proposes to utilize Gauss period Normal Basis (GNB) for Pollard’s rho method, and then considers to acceler...

medical x-rays are the largest man-made source of public exposure to ionizing radiation. while the benefits of computed tomography (ct) are well known in accurate diagnosis, those benefits are not risk free. ct is a device with higher patient dose in comparison with other conventional radiation procedures. so it is important to avoid conditions where the amount of radiation used is more than th...

This paper provides a framework that reduces the computational complexity of the discrete logarithm problem. The paper describes how to decompose the initial DLP onto several DLPs of smaller dimensions. Decomposability of the DLP is an indicator of potential vulnerability of encrypted messages transmitted via open channels of the Internet or within corporate networks. Several numerical examples...

We present a study on the use of Pell hyperbolas in cryptosystems with security based discrete logarithm problem. Specifically, after introducing group structure over generalized (and also giving explicit isomorphisms classical hyperbolas), we provide parameterization both an algebraic and geometrical approach. The particular that propose appears to be useful from cryptographic point view becau...

In this paper, we present a new DLP-sponge construction to ensure integrity and privacy. This scheme solves problem related to small keys by introducing a double length construction: k ≈ 2r. Previous researcher show that the size of key k must be twice of the capacity c which will in turn affect the size of the underlying permutation: b = c + r. As c decreases, the bitrate r increases as well. ...
