Kar M, Singla M, Chandele A, Kabra SK, Lodha R, Medigeshi GR.
PMID: 28491890
Open Forum Infect Dis. 2017 Mar 23;4(2):ofx051. doi: 10.1093/ofid/ofx051. eCollection 2017.

Thrombocytopenia is a characteristic feature during the acute phase of dengue infection and has been found to associate with vascular leakage in severe dengue. Although dengue antigens have been observed in platelets, there is no strong evidence to suggest...

Dislocation emission at the Silicon/Silicon nitride interface: A million atom molecular dynamics simulation on parallel computers.

Physical review letters

Bachlechner ME, Omeltchenko A, Nakano A, Kalia RK, Vashishta P, Ebbsjo I, Madhukar A.
PMID: 11015901
Phys Rev Lett. 2000 Jan 10;84(2):322-5. doi: 10.1103/PhysRevLett.84.322.

Mechanical behavior of the Si(111)/Si(3)N4(0001) interface is studied using million atom molecular dynamics simulations. At a critical value of applied strain parallel to the interface, a crack forms on the silicon nitride surface and moves toward the interface. The...

Coupling length scales for multiscale atomistics-continuum simulations: atomistically induced stress distributions in Si/Si3N4 nanopixels.

Physical review letters

Lidorikis E, Bachlechner ME, Kalia RK, Nakano A, Vashishta P, Voyiadjis GZ.
PMID: 11497965
Phys Rev Lett. 2001 Aug 20;87(8):086104. doi: 10.1103/PhysRevLett.87.086104. Epub 2001 Aug 06.

A hybrid molecular-dynamics (MD) and finite-element simulation approach is used to study stress distributions in silicon/silicon-nitride nanopixels. The hybrid approach provides atomistic description near the interface and continuum description deep into the substrate, increasing the accessible length scales and...

Eur J Neurosci. 1990;2(5):430-450. doi: 10.1111/j.1460-9568.1990.tb00435.x.

In the rat the monoaminergic and neuropeptidergic innervation of the sympathetic visceral nuclei of the entire thoracic spinal cord has been analysed in serial horizontal sections using immunocytochemistry. Tyrosine hydroxylase (TH), Phenyl-ethanolamine-N-methyl-transferase (PNMT), 5-hydroxytryptamine (5-HT), substance P (SP) and...

1,3,5-trinitro-1,3,5-triazine decomposition and chemisorption on Al(111) surface: first-principles molecular dynamics study.

The Journal of chemical physics

Umezawa N, Kalia RK, Nakano A, Vashista P, Shimojo F.
PMID: 17600430
J Chem Phys. 2007 Jun 21;126(23):234702. doi: 10.1063/1.2200352.

We have investigated the decomposition and chemisorption of a 1,3,5-trinitro-1,3,5-triazine (RDX) molecule on Al(111) surface using molecular dynamics simulations, in which interatomic forces are computed quantum mechanically in the framework of the density functional theory (DFT). The real-space DFT...

Conformational effects on vibronic spectra and excited state dynamics of 3-fluorobenzoic acid dimer.

The Journal of chemical physics

Two conformational isomers of 3-fluorobenzoic acid dimer (3-FBA(2)) have been identified in a supersonic jet expansion by use of laser-induced fluorescence excitation (FE), UV-UV hole-burning, and dispersed fluorescence (DF) spectroscopic methods. In the FE spectrum, the S(1) origins of...

Vibrational and thermodynamic properties of β-HMX: a first-principles investigation.

The Journal of chemical physics

Wu Z, Kalia RK, Nakano A, Vashishta P.
PMID: 21639458
