GAMETOPHYTIC SELECTION IN RAPHANUS RAPHANISTRUM: A TEST FOR HERITABLE VARIATION IN POLLEN COMPETITIVE ABILITY.

Evolution; international journal of organic evolution

Snow AA, Mazer SJ.
PMID: 28581174
Evolution. 1988 Sep;42(5):1065-1075. doi: 10.1111/j.1558-5646.1988.tb02524.x.

Competition among many microgametophytes for a limited number of ovules can lead to both nonrandom fertilization by pollen genotypes and selection for greater sporophytic vigor. The evolutionary implications of this process depend on the extent of heritable genetic variation...

Rapid evolution in crop-weed hybrids under artificial selection for divergent life histories.

Evolutionary applications

Campbell LG, Snow AA, Sweeney PM, Ketner JM.
PMID: 25567859
Evol Appl. 2009 May;2(2):172-86. doi: 10.1111/j.1752-4571.2008.00051.x. Epub 2008 Dec 08.

When species hybridize, offspring typically exhibit reduced fitness and maladapted phenotypes. This situation has biosafety implications regarding the unintended spread of novel transgenes, and risk assessments of crop-wild hybrids often assume that poorly adapted hybrid progeny will not evolve...

Increased pre-dispersal seed predation in sunflower crop-wild hybrids.

Oecologia

Cummings CL, Alexander HM, Snow AA.
PMID: 28308321
Oecologia. 1999 Nov;121(3):330-338. doi: 10.1007/s004420050936.

The fitness of crop-wild hybrids can influence gene flow between crop and wild populations. Seed predation levels in crop-wild hybrid plants can be an important factor in determining plant fitness, especially in large-seeded crops such as sunflower. To determine...

Predictors of Inpatient Utilization among Veterans with Dementia.

Current gerontology and geriatrics research

Godwin KM, Morgan RO, Walder A, Bass DM, Judge KS, Wilson N, Snow AL, Kunik ME.
PMID: 24982674
Curr Gerontol Geriatr Res. 2014;2014:861613. doi: 10.1155/2014/861613. Epub 2014 May 29.

Dementia is prevalent and costly, yet the predictors of inpatient hospitalization are not well understood. Logistic and negative binomial regressions were used to identify predictors of inpatient hospital utilization and the frequency of inpatient hospital utilization, respectively, among veterans....

Evolution of magnetic polarons and spin-carrier interactions through the metal-insulator transition in Eu(1-x)Gd(x)O.

Physical review letters

Rho H, Snow CS, Cooper SL, Fisk Z, Comment A, Ansermet JP.
PMID: 11909499
Phys Rev Lett. 2002 Mar 25;88(12):127401. doi: 10.1103/PhysRevLett.88.127401. Epub 2002 Mar 12.

Raman scattering studies as functions of temperature, magnetic field, and Gd substitution are used to investigate the evolution of magnetic polarons and spin-carrier interactions through the metal-insulator transition in Eu(1-x)Gd(x)O. These studies reveal a spin-fluctuation-dominated paramagnetic (PM) regime for...

Quantum melting of the charge-density-wave state in 1T-TiSe2.

Physical review letters

Snow CS, Karpus JF, Cooper SL, Kidd TE, Chiang TC.
PMID: 14525324
Phys Rev Lett. 2003 Sep 26;91(13):136402. doi: 10.1103/PhysRevLett.91.136402. Epub 2003 Sep 24.

We report a Raman scattering study of low-temperature, pressure-induced melting of the charge-density-wave (CDW) phase of 1T-TiSe2. Our measurements reveal that the collapse of the CDW state occurs in three stages: (i) For P

Documentation of antipsychotic use and indications for newly diagnosed, nonaggressive dementia patients.

Primary care companion to the Journal of clinical psychiatry

Dhawan N, Steele AB, Morgan RO, Snow AL, Davila JA, Kunik ME.
PMID: 18458729
Prim Care Companion J Clin Psychiatry. 2008;10(2):97-102. doi: 10.4088/pcc.v10n0202.

OBJECTIVE: The purpose of this study was to determine the prevalence of antipsychotic use among nonaggressive patients with newly diagnosed dementia and to examine indications for antipsychotic use.METHOD: Patients had to be veterans older than 60 years, newly diagnosed...

Nondestructive experimental determination of bimaterial rectangular cantilever spring constants in water.

The Review of scientific instruments

Snow DE, Weeks BL, Kim DJ, Pitchimani R, Hope-Weeks LJ.
PMID: 19044356
Rev Sci Instrum. 2008 Aug;79(8):083706. doi: 10.1063/1.2969031.

In order to address the issue of spring constant calibration in viscous fluids such as water, a new method is presented that allows for the experimental calibration of bimaterial cantilever spring constants. This method is based on modeling rectangular...

A simple method for the removal of thiols on gold surfaces using an NH4OH-H2O2-H2O solution.

Scanning

Kim DJ, Pitchimani R, Snow DE, Hope-Weeks LJ.
PMID: 18241042
Scanning. 2008 Mar-Apr;30(2):118-22. doi: 10.1002/sca.20089.

The removal behavior of self-assembled monolayers (SAMs) of thiol molecules on a gold substrate by an NH(4)OH-H(2)O(2)-H(2)O solution was studied using attenuated total reflectance infrared spectroscopy (ATR-IR) and atomic force microscopy (AFM). Furthermore, the impact of the concentration of...

Pain management and the primary care encounter: opportunities for quality improvement.

Journal of primary care & community health

Gannon M, Qaseem A, Snow V, Snooks Q.
PMID: 23804661
J Prim Care Community Health. 2011 Jan 01;2(1):37-44. doi: 10.1177/2150131910386377.

PURPOSE: The purpose of this pilot study was to create a comprehensive pain management educational toolkit for the primary care physician that offers guidance on current standards of care and quality improvement techniques to help curb educational and quality...

A simple and cost-effective method of DNA extraction from small formalin-fixed paraffin-embedded tissue for molecular oncologic testing.

BMC clinical pathology

Snow AN, Stence AA, Pruessner JA, Bossler AD, Ma D.
