Ba(1-x)K(x)Mn2As2: an antiferromagnetic local-moment metal.

Physical review letters

Pandey A, Dhaka RS, Lamsal J, Lee Y, Anand VK, Kreyssig A, Heitmann TW, McQueeney RJ, Goldman AI, Harmon BN, Kaminski A, Johnston DC.
PMID: 22463561
Phys Rev Lett. 2012 Feb 24;108(8):087005. doi: 10.1103/PhysRevLett.108.087005. Epub 2012 Feb 23.

The compound BaMn2As2 with the tetragonal ThCr2Si2 structure is a local-moment antiferromagnetic insulator with a Néel temperature T(N)=625 K and a large ordered moment μ=3.9μ(B)/Mn. We demonstrate that this compound can be driven metallic by partial substitution of Ba...

Turbidimetric determination of anionic polyacrylamide in low carbon soil extracts.

Journal of environmental quality

Kang J, Sowers TD, Duckworth OW, Amoozegar A, Heitman JL, McLaughlin RA.
PMID: 25602431
J Environ Qual. 2013 Nov;42(6):1902-7. doi: 10.2134/jeq2013.07.0279.

Concerns over runoff water quality from agricultural lands and construction sites have led to the development of improved erosion control practices, including application of polyacrylamide (PAM). We developed a quick and reliable method for quantifying PAM in soil extracts...

Differences in Left Versus Right Ventricular Electrophysiological Properties in Cardiac Dysfunction and Arrhythmogenesis.

Arrhythmia & electrophysiology review

Molina CE, Heijman J, Dobrev D.
PMID: 27403288
Arrhythm Electrophysiol Rev. 2016 May;5(1):14-9. doi: 10.15420/aer.2016.8.2.

A wide range of ion channels, transporters, signaling pathways and tissue structure at a microscopic and macroscopic scale regulate the electrophysiological activity of the heart. Each region of the heart has optimised these properties based on its specific role...

Regional differences in use of endoscopic ultrasonography in Ontario: a population-based retrospective cohort study.

CMAJ open

James PD, Hegagi M, Antonova L, Tinmouth J, Heitman SJ, Simone C, Yeung E, Yong E.
PMID: 28600449
CMAJ Open. 2017 Jun 07;5(2):E437-E443. doi: 10.9778/cmajo.20160153.

BACKGROUND: Endoscopic ultrasonography is a safe and accurate modality for evaluating and managing hepatobiliary and gastrointestinal conditions (malignant and nonmalignant); its use is increasing. The aim of this study was to describe regional trends in the use of endoscopic...

Assessment of Ankle-Subtalar-Joint-Complex Laxity Using an Instrumented Ankle Arthrometer: An Experimental Cadaveric Investigation.

Journal of athletic training

Kovaleski JE, Hollis J, Heitman RJ, Gurchiek LR, Pearsall AW.
PMID: 12937569
J Athl Train. 2002 Dec;37(4):467-474.

OBJECTIVE: To show the relationship between direct measurements of tibial-calcaneal bone motion and instrumented measurements of ankle-subtalar-joint-complex laxity using a portable ankle arthrometer; to assess within and between-tester measurement reliability; and to determine if the ankle arthrometer can detect...

Generation of genetic diversity in microsporidia via sexual reproduction and horizontal gene transfer.

Communicative & integrative biology

Lee SC, Weiss LM, Heitman J.
PMID: 19907704
Commun Integr Biol. 2009 Sep;2(5):414-7. doi: 10.4161/cib.2.5.8846.

Microsporidia are obligate intracellular pathogens mainly infecting both vertebrate and invertebrate hosts. The group comprises approximately 150 genera with 1,200 species. Due to sequence divergence phylogenic reconstructions that are solely based on DNA sequence have been unprecise for these...

Production and properties of vacuum evaporated films of thorium fluoride.

Applied optics

Heitmann W, Ritter E.
PMID: 20062461
Appl Opt. 1968 Feb 01;7(2):307-9. doi: 10.1364/AO.7.000307.

Experiments for the production of vacuum evaporated films of thorium oxyfluoride showed that these films cannot be produced by direct evaporation of thorium oxyfluoride, because this material decomposes at approximately 1000 degrees C into ThF(4) and ThO(2). ThF(4) evaporates...

Effects of transition metal substitutions on the incommensurability and spin fluctuations in BaFe2As2 by elastic and inelastic neutron scattering.

Physical review letters

Kim MG, Lamsal J, Heitmann TW, Tucker GS, Pratt DK, Khan SN, Lee YB, Alam A, Thaler A, Ni N, Ran S, Bud'ko SL, Marty KJ, Lumsden MD, Canfield PC, Harmon BN, Johnson DD, Kreyssig A, McQueeney RJ, Goldman AI.
PMID: 23215117
Phys Rev Lett. 2012 Oct 19;109(16):167003. doi: 10.1103/PhysRevLett.109.167003. Epub 2012 Oct 19.

The spin fluctuation spectra from nonsuperconducting Cu-substituted, and superconducting Co-substituted, BaFe(2)As(2) are compared quantitatively by inelastic neutron scattering measurements and are found to be indistinguishable. Whereas diffraction studies show the appearance of incommensurate spin-density wave order in Co and...

Reactively evaporated films of scandia and yttria.

Applied optics

Heitmann W.
PMID: 20125296
Appl Opt. 1973 Feb 01;12(2):394-7. doi: 10.1364/AO.12.000394.

Sc(2)O(3) and Y(2)O(3) films were prepared by evaporation from resistance heated boats in a residual gas atmosphere of oxygen. Films of much lower absorptance were obtained than from coatings produced in high vacuum. The short wavelength limit of high...

Comparative analysis of calcineurin signaling between Candida dubliniensis and Candida albicans.

Communicative & integrative biology

Zhang J, Heitman J, Chen YL.
PMID: 22808313
Commun Integr Biol. 2012 Mar 01;5(2):122-6. doi: 10.4161/cib.18833.

Candida dubliniensis, an emerging fungal pathogen, is the closest known species to the established pathogenic species Candida albicans. Despite the fact that these two species share > 80% genome sequence identity, they exhibit distinct properties such as less hyphal...
