Discovery of the interstellar chiral molecule propylene oxide (CH₃CHCH₂O).

Science (New York, N.Y.)

McGuire BA, Carroll PB, Loomis RA, Finneran IA, Jewell PR, Remijan AJ, Blake GA.
PMID: 27303055
Science. 2016 Jun 17;352(6292):1449-52. doi: 10.1126/science.aae0328. Epub 2016 Jun 14.

Life on Earth relies on chiral molecules-that is, species not superimposable on their mirror images. This manifests itself in the selection of a single molecular handedness, or homochirality, across the biosphere. We present the astronomical detection of a chiral...

Depression-Related Behavioral Tests.

Current protocols in mouse biology

Powell TR, Fernandes C, Schalkwyk LC.
PMID: 26069008
Curr Protoc Mouse Biol. 2012 Jun 01;2(2):119-27. doi: 10.1002/9780470942390.mo110176.

Overlapping characteristics between human depressive phenotypes and mouse behaviors has led to the creation of mouse models that aim to investigate the pathophysiology and treatment of unipolar depression. Behavioral tests in mice are used to assess and quantify the...

Obtaining the Hessian from the force covariance matrix: Application to crystalline explosives PETN and RDX.

The Journal of chemical physics

Pereverzev A, Sewell TD.
PMID: 25854231
J Chem Phys. 2015 Apr 07;142(13):134110. doi: 10.1063/1.4916614.

We show that for solids the effective Hessian matrix, averaged over the canonical ensemble, can be calculated from the force covariance matrix. This effective Hessian reduces to the standard Hessian as the temperature approaches zero, while at finite temperatures...

Characteristics of energy exchange between inter- and intramolecular degrees of freedom in crystalline 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) with implications for coarse-grained simulations of shock waves in polyatomic molecular crystals.

The Journal of chemical physics

Kroonblawd MP, Sewell TD, Maillet JB.
PMID: 26874491
J Chem Phys. 2016 Feb 14;144(6):064501. doi: 10.1063/1.4941332.

In this report, we characterize the kinetics and dynamics of energy exchange between intramolecular and intermolecular degrees of freedom (DoF) in crystalline 1,3,5-triamino-2,4,6-trinitrobenzene (TATB). All-atom molecular dynamics (MD) simulations are used to obtain predictions for relaxation from certain limiting...

Toward an Integrated Classification of Ecosystems: Defining Opportunities for Managing Fish and Forest Health.

Environmental management

Rieman BE, Lee DC, Thurow RF, Hessburg PF, Sedell JR.
PMID: 10667948
Environ Manage. 2000 Apr;25(4):425-444. doi: 10.1007/s002679910034.

/ Many of the aquatic and terrestrial ecosystems of the Pacific Northwest United States have been simplified and degraded in part through past land-management activities. Recent listings of fishes under the Endangered Species Act and major new initiatives for...

First-principles-based calculations of vibrational normal modes in polyatomic materials with translational symmetry: application to PETN molecular crystal.

The journal of physical chemistry. B

Velizhanin KA, Kilina S, Sewell TD, Piryatinski A.
PMID: 18821785
J Phys Chem B. 2008 Oct 23;112(42):13252-7. doi: 10.1021/jp804980a. Epub 2008 Sep 27.

Numerical studies of vibrational energy transport and associated (non)linear infrared and Raman response in polyatomic materials require knowledge of the multidimensional vibrational potential-energy surface and the ability to perform normal-mode analysis on that potential. The presence of translational symmetry,...

Chemical changes of lakes within the mount st. Helens blast zone.

Science (New York, N.Y.)

Wissmar RC, Devol AH, Nevissi AE, Sedell JR.
PMID: 17736248
Science. 1982 Apr 09;216(4542):175-8. doi: 10.1126/science.216.4542.175.

Differences in the dissolved chemistry of lakes devastated by the 18 May 1980 eruption of Mount St. Helens are attributable to location relative to the lateral blast trajectory of the eruption and to the emplacement of mineral deposits. Elemental...

Science. 1982 Apr 09;216(4542):178-81. doi: 10.1126/science.216.4542.178.

Loadings of dissolved organics and suspended particulates from destroyed forests and volcanic debris produced by the 18 May 1980 eruption of Mount St. Helens altered the trophic structure of many blast zone lakes to the extent that anoxic conditions...
