Photocatalytic C-F alkylation; Facile access to multifluorinated arenes
(Royal Society of Chemistry, 2015-09-29)C–F functionalizations that provide C–C bonds are challenging synthetic transformations, due in part to the large C–F bond strength, short bond length, nonpolarizable nature, the production of fluoride, and the regioselectivity-in ... -
Photon-photon correlations as a probe of vacuum-induced coherence effects
(American Physical Society, 2008-03-27)We show how the effects of vacuum-induced coherence can be realized by studying photon-photon correlation in the pi-polarized fluorescence in the j=1/2 to j=1/2 transition. These effects should thus be observable in ... -
Phylogenetic and metabolic diversity of Planctomycetes from anaerobic, sulfide- and sulfur-rich Zodletone Spring, Oklahoma
(American Society for Microbiology, 2007-08)We investigated the phylogenetic diversity and metabolic capabilities of members of the phylum Planctomycetes in the anaerobic, sulfide-saturated sediments of a mesophilic spring (Zodletone Spring) in southwestern Oklahoma. ... -
Phylogenetic diversities and community structure of members of the extremely halophilic Archaea (order Halobacteriales) in multiple saline sediment habitats
(American Society for Microbiology, 2012-03)We investigated the phylogenetic diversity and community structure of members of the halophilic Archaea (order Halobacteriales) in five distinct sediment habitats that experience various levels of salinity and salinity ... -
Phylogeographic analysis reveals association of tick-borne pathogen, Anaplasma marginale, MSP1a sequences with ecological traits affecting tick vector performance
(BioMed Central, 2009-09-01)Background: The tick-borne pathogen Anaplasma marginale, which is endemic worldwide, is the type species of the genus Anaplasma (Rickettsiales: Anaplasmataceae). Rhipicephalus (Boophilus) microplus is the most important ... -
Physical activity engagement outside of college physical education: Application of the transtheoretical model
(P N G Publications, 2021-09-01)Objective: In this study, we examined physical activity (PA) engagement outside of college physical education (PE) classes using the Transtheoretical Model (TTM). Methods: Overall, 414 university students enrolled in PE ... -

Physiological genetics of aluminum tolerance in the wheat cultivar Atlas 66
(Crop Science Society of America, 2002-09)Aluminum toxicity limits wheat (Triticum aestivum L.) production on acidic soils. The wheat cultivar Atlas 66 reportedly may have both more than one Al tolerance gene and more than one Al tolerance mechanism. The purpose ... -
Pictorial key for identification of immature stages of common ixodid ticks found in pastures in Oklahoma
(Society of Southwestern Entomologists, 2017-03)Many species of ixodid ticks in the United States are parasitic on cattle and pose a threat to veterinary and public health for those engaged in occupations in pasturelands. While encountered often, nymphs and larvae of ... -
Pilot study of impact of a pedal desk on postprandial responses in sedentary workers
(Ovid Technologies (Wolters Kluwer Health), 2018-10)Physical inactivity has been linked to rates of obesity, diabetes, and heart disease through insulin resistance and other mechanisms. Although sedentary workplace environments have unintentionally contributed to the risk ... -
Planar THz quasioptics
(AIP Publishing, 2004-08-09)Two-dimensional (2D) quasioptical elements are demonstrated as guiding structures in the THz frequency regime. A planar polyethylene lens is incorporated in a parallel metal plate structure and is shown to focus guided THz ... -
Plane curves with small linear orbits, I
(Association des Annales de l'Institut Fourier, 2000)In this paper we compute the degree of the closure of the linear orbits of most curves with positive dimensional stabilizers. Our tool is a nonsingular variety dominating the orbit closure, which we construct by a blow-up ... -
Plasmodium falciparum: Release of circumsporozoite protein by sporozoites in the mosquito vector
(Elsevier BV, 1992)The release of circumsporozoite (CS) protein by Plasmodium falciparum sporozoites was investigated to identify factors regulating this process within infected Anopheles gambiae mosquitoes. The potential for sporozoites to ... -
Plasmodium falciparum: The population structure of mature gametocyte cultures has little effect on their innate fertility
(Elsevier BV, 1994)In vitro cultured Plasmodium falciparum gametocytes were fed to Anopheles gambiae (G3) mosquitoes to identify parasite population characteristics useful for predicting successful mosquito infections. Parameters were collected ... -
Plastic ribbon THz waveguides
(AIP Publishing, 2000-10-01)We report an experimental and theoretical study of single mode, guided wave propagation in plastic ribbons. Using cylindrical THz optics, we obtain excellent quasioptic coupling between freely propagating THz waves and a ... -

Poincare homology sphere, lens space surgeries, and some knots with tunnel number two
(2015-04-25)We exhibit an infinite family of knots in the Poincare homology sphere with tunnel number 2 that have a lens space surgery. Notably, these knots are not doubly primitive and provide counterexamples to a few conjectures. ... -
Point source terahertz optics
(AIP Publishing, 1988-10-17)We demonstrate an ultrafast 10 micro-m sized, electric dipole source of terahertz radiation closely coupled to a 1 cm spherical mirror. This optical approach has the advantages of subpicosecond response times with essentially ... -
Polariton and free-exciton-like photoluminescence in ZnO
(AIP Publishing, 2001-12-03)An unusual photoluminescence line X has been observed in ZnO at an energy between that of the common donor-bound excitons (DBEs) and the free excitons (FEs). In the presence of a high carrier concentration, induced by a ... -
Population dynamics in Floquet realisation of Harper-Hofstadter Hamiltonian
(2015-04-21)We study the recent Floquet-realisation of the Harper-Hofstadter model in a gas of cold bosonic atoms. We study in detail the scattering processes in this system in the weakly interacting regime due to the interplay of ...
