This paper presents a new protocol named " Link State Over MAC " (LSOM) for Optical Ethernet switches to allow the use of active loop topologies, like meshes, in Metropolitan Area Networks (MAN) or even Wide Area Networks (WAN) backbone. In this respect, LSOM is an alternative to a ring topology as proposed in draft IEEE 802.17 Resilient Packet Ring (RPR) or a tree topology using IEEE802.1D Rap...

The authors investigated the utility of both a nontreponemal (RPR) test and a treponemal (FTA-ABS) test for the diagnosis of primary syphilis during the emergence of the HIV epidemic in southern Africa. The serological tests were performed on 868 patients with genital ulcerations, seen in five centres. While primary syphilis was diagnosed by multiplex PCR in 163 cases (18.8%), the overall RPR a...

In this paper, modeling and experimentation of a Rectangular Patch Resonator (RPR) covered with a dielectric superstrate are investigated. The RPR criteria are established theoretically and experimentally, to be used in future prospects as an electromagnetic (EM) sensor for the characterization of superstrates. The theoretical model is based on the moment method (MoM) via Galerkin’s approach, i...

Presently, the diagnosis of syphilis is dependent mainly on serological tests. The most widely used screening tests for syphilis are the VDRL and the rapid plasma reagin (RPR) and for confirmation, the fluorescent treponemal antibody (FTA) and the treponema pallidum hemagglutination (TPHA) tests. The four alternative modes for diagnosis of syphilis can be a) VDRL + FTA, b) VDRL + TPHA, c) RPR +...

Background and Aims: The decision to treat chronic hepatitis B Virus infection (CHB) may necessitate an assessment of the degree liver fibrosis. Guidelines recommend Fibroscan examination in such cases. However, it is costly not widely available. Red cell distribution width (RDW) platelet count are simple parameters obtained from blood pictures; their ratio RDW (RPR) was claimed correlate with ...

This paper presents a new approach for the determination of 3 − RPR planar parallel robot assembly modes. In this approach, the parallel robot is considered as a multi robot system. The segments are then regarded as serial robots moving a common load. The proposed approach is based on a parallel robot Jacobian matrix factorization. This factorization is an extension of global formalism develope...

In social networks, analysing the explicit interactions among users can help in inferring hierarchical relationships and roles that may be implicit. In this thesis, we focus on two objectives: detecting hierarchical relationships between users and inferring the hierarchical roles of users interacting via the same online communication medium. In both cases, we show that considering the temporal ...

OBJECTIVE To develop a simple predictive model for significant fibrosis and cirrhosis in chronic hepatitis B (CHB) using the routine hematological parameters of a complete blood count. METHODS A total of 458 eligible CHB patients who had undergone a liver biopsy were randomly divided into two cohorts: an estimation group (n = 310) and a validation group (n = 148). Liver histology was assessed...

By using destination stripping and shortest-path routing, the new standard IEEE 802.17 resilient packet ring (RPR) allows for spatial reuse, resulting in a significantly increased capacity compared to source-stripping legacy ring networks. We show that for multicast traffic the performance of RPR reduces to that of legacy ring networks that do not support spatial reuse. We propose a bandwidth-e...

Apoptosis is a specific form of cell death that is important for normal development and tissue homeostasis. Caspases are critical executioners of apoptosis, and living cells prevent their inappropriate activation through inhibitor of apoptosis proteins (IAPs). In Drosophila, caspase activation depends on the IAP antagonists, Reaper (Rpr), Head involution defective (Hid), and Grim. These protein...
