The energy landscape of silicon systems and its description by force fields, tight binding schemes, density functional methods and Quantum Monte Carlo methods (2009)

Ghasemi, S. Alireza, Amsler, Maximilian, Hennig, Richard G., Roy, Shantanu, Goedecker, Stefan, Umrigar, C. J., ...

The accuracy of the energy landscape of silicon systems obtained from various density functional methods, a tight binding scheme and force fields is studied. Quantum Monte Carlo results serve as...

The performance of Minima Hopping and Evolutionary Algorithms for cluster structure prediction (2008)

Schoenborn, Sandro E., Goedecker, Stefan, Roy, Shantanu, Oganov, Artem R.

We compare Evolutionary Algorithms with Minima Hopping for global optimization in the field of cluster structure prediction. We introduce a new {\em average offspring} recombination operator and...

A Bell-Evans-Polanyi principle for molecular dynamics trajectories and its implications for global optimization (2007)

Roy, Shantanu, Hellmann, Waldemar, Goedecker, Stefan

The Bell-Evans-Polanyi principle that is valid for a chemical reaction that proceeds along the reaction coordinate over the transition state is extended to molecular dynamics trajectories that in...

Genreal kinetic invariant modal of dissolution of large polydisperse particles (1996)

Dabral, Mahendra M, Roy, Shantanu, Bhaskarwar, Ashok N

The kinetic invariant proposed earlierfor dissolution followed by chemical reaction of large,monodisperse particles(A N Bhaskarwar,AIchE J,37(1991)340-346)Has been extend for large polydisperes...

Multiplex Real-Time PCR Assay Using Scorpion Probes and DNA Capture for Genotype-Specific Detection of Giardia lamblia on Fecal Samples

Ng, Cherie T., Gilchrist, Carol A., Lane, Ariel, Roy, Shantanu, Haque, Rashidul, Houpt, Eric R.

Two major genotypic assemblages of Giardia lamblia infect humans; the epidemiologic significance of this phenomenon is poorly understood. We developed a single-vessel multiplex real-time PCR (qPCR)...

Real-Time-PCR Assay for Diagnosis of Entamoeba histolytica Infection

Roy, Shantanu, Kabir, Mamun, Mondal, Dinesh, Ali, Ibne Karim M., Petri, William A., Haque, Rashidul

We developed a real-time-PCR assay utilizing a molecular-beacon probe for the detection of Entamoeba histolytica and compared its sensitivity to stool antigen detection and traditional PCR. A total...

Entamoeba histolytica Infection in Children and Protection from Subsequent Amebiasis

Haque, Rashidul, Mondal, Dinesh, Duggal, Priya, Kabir, Mamun, Roy, Shantanu, Farr, Barry M., ...

The contribution of amebiasis to the burden of diarrheal disease in children and the degree to which immunity is acquired from natural infection were assessed in a 4-year prospective observational...

Evaluation of Entamoeba histolytica Antigen and Antibody Point-of-Care Tests for the Rapid Diagnosis of Amebiasis▿

Leo, Megan, Haque, Rashidul, Kabir, Mamun, Roy, Shantanu, Lahlou, Rita Marie, Mondal, Dinesh, ...

The bedside diagnosis of amebiasis could improve patient care. In Bangladesh and Vietnam, a novel and simple-to-use Entamoeba histolytica rapid antigen test had 97% sensitivity and 100% specificity...

Evidence for a Link between Parasite Genotype and Outcome of Infection with Entamoeba histolytica▿ †

Ali, Ibne Karim M., Mondal, Utpal, Roy, Shantanu, Haque, Rashidul, Petri, William A., Clark, C. Graham

The factors determining whether a person infected with Entamoeba histolytica develops disease remain obscure. To investigate whether the parasite genome contributes to the outcome, we have...

Tissue Invasion by Entamoeba histolytica: Evidence of Genetic Selection and/or DNA Reorganization Events in Organ Tropism

Ali, Ibne Karim M., Solaymani-Mohammadi, Shahram, Akhter, Jasmine, Roy, Shantanu, Gorrini, Chiara, Calderaro, Adriana, ...

Entamoeba histolytica infection may have various clinical manifestations. Nine out of ten E. histolytica infections remain asymptomatic, while the remainder become invasive and cause disease. The...
