Simultaneous Confidence Band for the Difference of Segmented Linear Models.

Journal of statistical planning and inference

Yothers G, Sampson AR.
PMID: 26166937
J Stat Plan Inference. 2011 Feb;141(2):1059-1068. doi: 10.1016/j.jspi.2010.09.011.

Consider comparing between two treatments a response variable, whose expectation depends on the value of a continuous covariate in some nonlinear fashion. We fit separate segmented linear models to each treatment to approximate the nonlinear relationship. For this setting,...

Lower Extremity Kinematics During a Drop Jump in Individuals With Patellar Tendinopathy.

Orthopaedic journal of sports medicine

Rosen AB, Ko J, Simpson KJ, Kim SH, Brown CN.
PMID: 26665034
Orthop J Sports Med. 2015 Mar 18;3(3):2325967115576100. doi: 10.1177/2325967115576100. eCollection 2015 Mar.

BACKGROUND: Patellar tendinopathy (PT) is a common degenerative condition in physically active populations. Knowledge regarding the biomechanics of landing in populations with symptomatic PT is limited, but altered mechanics may play a role in the development or perpetuation of...

Reviewing an Original Research Manuscript for the International Journal of Exercise Science: A Guide for Students and Professionals.

International journal of exercise science

Simpson KJ.
PMID: 27182294
Int J Exerc Sci. 2008 Apr 15;1(2):43-49. eCollection 2008.

Considerations for the review process of manuscripts submitted to the International Journal of Exercise Science are presented. Initial steps to evaluation include reading the abstract to determine your ability as a reviewer, becoming familiar with the journal requirements, and...

Natural history of cavernous haemangiomata.

Lancet (London, England)

SIMPSON JR.

Interplay of ionic and structural heterogeneity on functional action potential duration gradients: Implications for arrhythmogenesis.

Chaos (Woodbury, N.Y.)

Sampson KJ, Henriquez CS.
PMID: 12779610
Chaos. 2002 Sep;12(3):819-828. doi: 10.1063/1.1497735.

Action potential duration (APD) dispersion in the heart is governed by the underlying cellular architecture and the spatial distribution of the membrane properties. Understanding the contribution of each factor is important in designing more effective methods for the control...

Wavelength dependence of nitrate radical quantum yield from peroxyacetyl nitrate photolysis: experimental and theoretical studies.

The journal of physical chemistry. A

Flowers BA, Stanton JF, Simpson WR.
PMID: 17958340
J Phys Chem A. 2007 Nov 15;111(45):11602-7. doi: 10.1021/jp0749118. Epub 2007 Oct 24.

The photolysis wavelength dependence of the nitrate radical quantum yield for peroxyacetyl nitrate (CH(3)C(O)OONO(2), PAN) is investigated. The wavelength range used in this work is between 289 and 312 nm, which mimics the overlap of the solar flux available...

Effect of gamma-Irradiation on the Biosynthesis of Carotenoids in the Tomato Fruit.

Plant physiology

Villegas CN, Chichester CO, Raymundo LC, Simpson KL.
PMID: 16658245
Plant Physiol. 1972 Dec;50(6):694-7. doi: 10.1104/pp.50.6.694.

Fruits of the lutescent tomato genetic line were exposed to gamma-radiation at different stages of maturity to determine the effect of ionizing radiation on carotenoid synthesis in the ripening fruit. Irradiation generally resulted in the inhibition of carotenogenesis. The...

Absolute activity of (133)Ba by liquid scintillation coincidence counting using the 4pi(e,X)-gamma extrapolation technique.

Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine

Simpson BR, van Wyngaardt WM.
PMID: 18358732
Appl Radiat Isot. 2008 Jun-Jul;66(6):929-33. doi: 10.1016/j.apradiso.2008.02.036. Epub 2008 Feb 08.

The Technical Committee for Ionizing Radiation (TCRI) of the Asia Pacific Metrology Programme (APMP) recently organized a regional key comparison of activity measurements of the radionuclide (133)Ba. This paper reports on absolute measurements made at the National Metrology Institute...

Dielectric response of aligned semiconducting single-wall nanotubes.

Physical review letters

Fagan JA, Simpson JR, Landi BJ, Richter LJ, Mandelbaum I, Bajpai V, Ho DL, Raffaelle R, Walker AR, Bauer BJ, Hobbie EK.
PMID: 17501312
Phys Rev Lett. 2007 Apr 06;98(14):147402. doi: 10.1103/PhysRevLett.98.147402. Epub 2007 Apr 06.

We report measurements of the full intrinsic optical anisotropy of isolated single-wall carbon nanotubes (SWNTs). By combining absorption spectroscopy with transmission ellipsometry and polarization-dependent resonant Raman scattering, we obtain the real and imaginary parts of the SWNT permittivity from...
