Self-collected glans and rectal swab specimens from men who have sex with men (MSM) may be appropriate, convenient specimens for testing. We evaluated the use of self-collected swabs for the detection of Chlamydia trachomatis and Neisseria gonorrhoeae by a transcription-mediated amplification test (AC2; Aptima Combo 2; Gen-Probe Inc.) and a strand displacement amplification test (SDA; ProbeTec;...

Geometrical disorder is present in many physical situations giving rise to eigenvalue problems. The simplest case of diffusion on a random lattice with fluctuating site connectivities is studied analytically and by exact numerical diagonalizations. Localization of eigenmodes is shown to be induced by geometrical defects, that is sites with abnormally low or large connectivities. We expose a " s...

This paper identifies various concepts involved in social networks for anonymizing the original details of the user. We focus on the various methods that can be applied for applying the anonymization techniques. The methods used are re-identification, k-isomorphism, k-automorphism and k w -SDA. These methods are used to provide the security and privacy for each user and the community in the soc...

Scattered Dropping Attack (SDA) is a simple yet very powerful denial of service (DoS) attack that is effective on both TCP and UDP based MANETs. The simulation results clearly show the impact of proposed attack on the network throughput, bandwidth wastage and received data quality. It has also been observed that even though the TCP congestion control is adaptable to the packet losses but in cas...

Nuisance Attribute Projection (NAP) provides an effective method of removing the unwanted session variability in a Support Vector Machine (SVM) based speaker recognition system by removing the principal components of this variability. There is no guarantee with the methods proposed, however, that desired speaker variability is retained. This paper investigates the possibility of training NAP di...

Methods An ongoing prospective study conducted from June 2012October 2013 in 90 HIV seropositive patients presenting with various complaints. CSF and lymphnode aspirates were subjected to preliminary microscopic examination, c (Giemsa staining, mucicarmine staining, negative staining and Gram’s staining). Latex agglutination test was done for CSF samples. Sampls inoculated on SDA at 37C and 25C...

A new doubling algorithm – Alternating-Directional Doubling Algorithm (ADDA) – is developed for computing the unique minimal nonnegative solution of an M -Matrix Algebraic Riccati Equation (MARE). It is argued by both theoretical analysis and numerical experiments that ADDA is always faster than two existing doubling algorithms – SDA of Guo, Lin, and Xu (Numer. Math., 103 (2006), pp. 393–412) a...
