Knowledge of why some product line architecture (PLA) consists of the specific features and feature interactions that constitute its overall structure is an invaluable resource for an architect. However, most PLA modeling techniques do not model these concepts explicitly. This requires that the architect express rationale separately, which increases the(More)
BACKGROUND & OBJECTIVES Apoptosis causes a decline in the counts of uninfected bystander CD4+ T cells in HIV infection. The rate of disease progression of HIV infection is considered to be faster in the developing countries. The present study was carried out to investigate certain markers for apoptosis in immunopathogensis of disease in HIV infected south(More)
Parallel simulation techniques are often employed to meet the computational requirements of large hardware simulations in order to reduce simulation time. In addition, partitioning for parallel simulations has been shown to be vital for achieving higher simulation throughput. This paper presents the results of our partitioning studies conducted on an(More)
Molecular xenomonitoring of filariasis is the detection of filarial DNA in mosquitoes by PCR and a useful tool for monitoring transmission. DNA extraction coupled with PCR allows rapid detection of the presence or absence of the filarial parasite in vector mosquitoes compared to traditional method of manual dissection of the mosquito and observation for(More)
India has made great progress towards the elimination of lymphatic filariasis. By 2015, most endemic districts had completed at least five annual rounds of mass drug administration (MDA). The next challenge is to determine when MDA can be stopped. We performed a simulation study with the individual-based model LYMFASIM to help clarify this. We used a(More)
Mathematical models of parasite transmission provide powerful tools for assessing the impacts of interventions. Owing to complexity and uncertainty, no single model may capture all features of transmission and elimination dynamics. Multi-model ensemble modelling offers a framework to help overcome biases of single models. We report on the development of a(More)
BACKGROUND & OBJECTIVE Individuals infected with HIV-1 have higher levels of chemokine producing cells compared to uninfected individuals. It is important to know the changes in chemokine levels associated with rate of progression of disease. There is a paucity of information on the plasma chemokines in HIV-1 infected individuals from India. We therefore(More)
BACKGROUND The monitoring and evaluation of lymphatic filariasis (LF) has largely relied on the detection of antigenemia and antibodies in human populations. Molecular xenomonitoring (MX), the detection of parasite DNA/RNA in mosquitoes, may be an effective complementary method, particularly for detecting signals in low-level prevalence areas where Culex is(More)
Vector mosquitoes of Japanese encephalitis (JE) breed mostly in rice fields, and human cases occur scattered over extended rural rice-growing areas. From this, one may surmise an ecological connection with the irrigation facilities and paddy cultivation. Furthermore, it has been hypothesized that a particular stage of paddy growth is a premonitory sign that(More)
