We investigate an exactly marginal N = 1 supersymmetric deformation of SU(N) N = 4 supersymmetric Yang-Mills theory discovered by Leigh and Strassler. We use a matrix model to compute the exactâ€¦ (More)

We compute the circular Wilson loop of N = 4 SYM theory at large N in the rank k symmetric and antisymmetric tensor representations. Using a quadratic Hermitian matrix model we obtain expressions forâ€¦ (More)

Dijkgraaf and Vafa (DV) have conjectured that the exact superpotential for a large class of N = 1 SUSY gauge theories can be extracted from the planar limit of a certain holomorphic matrix integral.â€¦ (More)

We study relevant deformations of the N = 2 superconformal theory on the world-volume of N D3 branes at an Akâˆ’1 singularity. In particular, we determine the vacuum structure of the mass-deformedâ€¦ (More)

BACKGROUND
HIV testing is a key component of HIV control efforts. We examined the distribution of HIV testing in a population-based sample from Guntur district in Andhra Pradesh, which is estimatedâ€¦ (More)

BACKGROUND
Prevention of mother to child transmission (PMTCT) is an important part of the effort to control HIV. PMTCT services are mostly provided at public sector government hospitals in India.â€¦ (More)

OBJECTIVE
To conduct composite economic analysis of HIV prevention interventions to inform efficient utilization of resources in India.
METHODS
We obtained output and economic cost data for theâ€¦ (More)

BACKGROUND
A rapid scaling up of HIV interventions in India is anticipated, but systematic information on how costs of HIV interventions change over time and programme scale is not available toâ€¦ (More)

BACKGROUND
Female sex workers and their clients play a prominent role in the HIV epidemic in India. Systematic data on the outputs, cost and efficiency for HIV prevention programmes for female sexâ€¦ (More)

We study the expectation value of a Polyakov-Maldacena loop that wraps the thermal circle k times in strongly coupled N = 4 super Yang-Mills theory. This is achieved by considering probe D3 and D5â€¦ (More)
