Communication: Designed diamond ground state via optimized isotropic monotonic pair potentials.

The Journal of chemical physics

Marcotte É, Stillinger FH, Torquato S.
PMID: 23425451
J Chem Phys. 2013 Feb 14;138(6):061101. doi: 10.1063/1.4790634.

We apply inverse statistical-mechanical methods to find a simple family of optimized isotropic, monotonic pair potentials (that may be experimentally realizable) whose classical ground state is the diamond crystal for the widest possible pressure range, subject to certain constraints...

Risk analysis of dust explosion scenarios using Bayesian networks.

Risk analysis : an official publication of the Society for Risk Analysis

Yuan Z, Khakzad N, Khan F, Amyotte P.
PMID: 25264172
Risk Anal. 2015 Feb;35(2):278-91. doi: 10.1111/risa.12283. Epub 2014 Sep 26.

In this study, a methodology has been proposed for risk analysis of dust explosion scenarios based on Bayesian network. Our methodology also benefits from a bow-tie diagram to better represent the logical relationships existing among contributing factors and consequences...

Efficient linear programming algorithm to generate the densest lattice sphere packings.

Physical review. E, Statistical, nonlinear, and soft matter physics

Marcotte É, Torquato S.
PMID: 23848802
Phys Rev E Stat Nonlin Soft Matter Phys. 2013 Jun;87(6):063303. doi: 10.1103/PhysRevE.87.063303. Epub 2013 Jun 07.

Finding the densest sphere packing in d-dimensional Euclidean space R(d) is an outstanding fundamental problem with relevance in many fields, including the ground states of molecular systems, colloidal crystal structures, coding theory, discrete geometry, number theory, and biological systems....

HCl adsorption on ice at low temperature: a combined X-ray absorption, photoemission and infrared study.

Physical chemistry chemical physics : PCCP

Parent P, Lasne J, Marcotte G, Laffon C.
PMID: 21409192
Phys Chem Chem Phys. 2011 Apr 21;13(15):7142-8. doi: 10.1039/c0cp02864a. Epub 2011 Mar 15.

The reaction of HCl on water ice provides a simple case for understanding dissociation and proton transfer in this non-optimal, incomplete solvation environment, playing a central role in atmospheric chemistry. This reaction has been repeatedly reported as thermally dependent,...

Strong intermolecular coupling between the HF stretching and H2O bending vibrations in HF:H2O binary amorphous solids: breakdown of the electrostatic description of the hydrogen bond.

The Journal of chemical physics

Marcotte G, Ayotte P.
PMID: 21428647
J Chem Phys. 2011 Mar 21;134(11):114522. doi: 10.1063/1.3562368.

The coupling mechanism between the HF stretching and H(2)O bending vibrations observed in the infrared spectra of HF:H(2)O binary amorphous solids is analyzed using a simple cluster model. The intermolecular vibrational coupling derived from electrostatic potentials is one order...

Fire hazard of titanium powder layers mixed with inert nano TiO.

Journal of hazardous materials

Yuan C, Cai J, Amyotte P, Li C, Bu Y, Liu K, Li G.
PMID: 29232613
J Hazard Mater. 2018 Mar 15;346:19-26. doi: 10.1016/j.jhazmat.2017.12.010. Epub 2017 Dec 06.

Metallic dust layers are highly sensitive to ignition from common ignition sources, even when mixed with high percentages of inert solids. In turn, dust layer fires are a potential ignition source for dust explosions or other damaging fires. Flame...

Glycogene expression profiles based on microarray data from cervical carcinoma HeLa cells with partially silenced E6 and E7 HPV oncogenes.

Infectious agents and cancer

Aco-Tlachi M, Carreño-López R, Martínez-Morales PL, Maycotte P, Aguilar-Lemarroy A, Jave-Suárez LF, Santos-López G, Reyes-Leyva J, Vallejo-Ruiz V.
PMID: 30038662

BACKGROUND: Aberrant glycosylation is a characteristic of tumour cells. The expression of certain glycan structures has been associated with poor prognosis. In cervical carcinoma, changes in the expression levels of some glycogenes have been associated with lymph invasion. Human...

Phenotypic, molecular and genetic-characterization of transformed human bronchial epithelial-cell strains.

International journal of oncology

Schiller J, Sabatini L, Bittner G, Pinkerman C, Mayotte J, Levitt M, Meisner L.
