Richardson WS, Wilson MC, Williams JW, Moyer VA, Naylor CD.
PMID: 10938177
JAMA. 2000 Aug 16;284(7):869-75. doi: 10.1001/jama.284.7.869.

Clinicians rely on knowledge about the clinical manifestations of disease to make clinical diagnoses. Before using research on the frequency of clinical features found in patients with a disease, clinicians should appraise the evidence for its validity, results, and...

Chalcogenide-halides of niobium (V). 1. Gas-phase structures of NbOBr(3), NbSBr(3), and NbSCl(3). 2. Matrix infrared spectra and vibrational force fields of NbOBr(3), NbSBr(3), NbSCl(3), and NbOCl(3).

Inorganic chemistry

Nowak I, Page EM, Rice DA, Richardson AD, French RJ, Hedberg K, Ogden JS.
PMID: 12588168
Inorg Chem. 2003 Feb 24;42(4):1296-305. doi: 10.1021/ic020405f.

The molecular structures of NbOBr(3), NbSCl(3), and NbSBr(3) have been determined by gas-phase electron diffraction (GED) at nozzle-tip temperatures of 250 degrees C, taking into account the possible presence of NbOCl(3) as a contaminant in the NbSCl(3) sample and...

Extra-pair paternity in relation to male age in Bullock's orioles.

Molecular ecology

Richardson DS, Burke T.
PMID: 10632862
Mol Ecol. 1999 Dec;8(12):2115-26. doi: 10.1046/j.1365-294x.1999.00832.x.

Single-locus minisatellite DNA profiling was used to assign paternity in a population of Bullock's orioles, Icterus galbula bullockii, and to determine the contribution of age to a male's success in obtaining extra-pair paternity. There was a very low rate...

Gas-phase molecular structures of third row transition-metal hexafluorides WF6, ReF6, OsF6, IrF6, and PtF6. An electron-diffraction and ab initio study.

Inorganic chemistry

Richardson AD, Hedberg K, Lucier GM.
PMID: 11232814
Inorg Chem. 2000 Jun 26;39(13):2787-93. doi: 10.1021/ic000003c.

The molecular structures of WF6, ReF6, OsF6, IrF6, and PtF6 have been measured by electron diffraction from the gases, the last from both PtF6 itself and from a vapor assumed to consist of a mixture of O2 and PtF6...

Product limit estimation for infectious disease data when the diagnostic test for the outcome is measured with uncertainty.

Biostatistics (Oxford, England)

Richardson BA, Hughes JP.
PMID: 12933514
Biostatistics. 2000 Sep;1(3):341-54. doi: 10.1093/biostatistics/1.3.341.

Low sensitivity and/or specificity of a diagnostic test for outcome results in biased estimates of the time to first event using product limit estimation. For example, if a test has low specificity, estimates of the cumulative distribution function (cdf)...

Climate change and marine plankton.

Trends in ecology & evolution

Hays GC, Richardson AJ, Robinson C.
PMID: 16701390
Trends Ecol Evol. 2005 Jun;20(6):337-44. doi: 10.1016/j.tree.2005.03.004.

Understanding how climate change will affect the planet is a key issue worldwide. Questions concerning the pace and impacts of climate change are thus central to many ecological and biogeochemical studies, and addressing the consequences of climate change is...

Methods for Analyzing the Role of DNA Methylation and Chromatin Structure in Regulating T Lymphocyte Gene Expression.

Biological procedures online

Lu Q, Richardson B.
PMID: 15448721
Biol Proced Online. 2004;6:189-203. doi: 10.1251/bpo89. Epub 2004 Sep 16.

Chromatin structure, determined in part by DNA methylation, is established during differentiation and prevents expression of genes unnecessary for the function of a given cell type. We reported that DNA methylation and chromatin structure contributes to lymphoid-specific ITGAL (CD11a)...

Phys Rev E Stat Nonlin Soft Matter Phys. 2006 Feb;73(2):026220. doi: 10.1103/PhysRevE.73.026220. Epub 2006 Feb 23.

A two-dimensional flow model is introduced with deterministic behavior consisting of bursts that become successively larger, with longer interburst time intervals between them. The system is symmetric in one variable and there are bursts on either side of ,...
