Roots of reciprocity: Gratitude and reputation in generalized exchange systems
(SAGE Publications, 2017-12-21)
Social scientists often study the flow of material and social support as generalized exchange systems. These systems are associated with an array of benefits to groups and communities, but their existence is problematic, ...
Factors driving the abundance of Ixodes ricinus ticks and the prevalence of zoonotic I. ricinus-borne pathogens in natural foci
(American Society for Microbiology, 2012-04-15)
Environmental factors may drive tick ecology and therefore tick-borne pathogen (TBP) epidemiology, which determines the risk to animals and humans of becoming infected by TBPs. For this reason, the aim of this study was ...
Capitalizing on automated workflow: Expediting metadata creation for electronic theses and dissertations at Oklahoma State University
(Oklahoma State University, 2020-10-30)
Conduct disorder and alcohol use disorder trajectories, predictors, and outcomes for Indigenous youth
(Elsevier BV, 2017-02)
Objective: The aim of this study was to identify separate and joint trajectories of conduct disorder (CD) and alcohol use disorder (AUD) DSM-IV diagnostic symptoms among American Indian and First Nation (Indigenous) youth ...
Peeling back the layers: First phylogenomic insights into the Ledebouriinae (Scilloideae, Asparagaceae)
(2020-11-04)
The Ledebouriinae (Scilloideae, Asparagaceae) are a widespread group of bulbous geophytes found predominantly throughout seasonal climates in sub-Saharan Africa, with a handful of taxa in Madagascar, the Middle East, India, ...
Optimized linear, quadratic and cubic interpolators for elementary function hardware implementations
(MDPI, 2016-04-08)
This paper presents a method for designing linear, quadratic and cubic interpolators that compute elementary functions using truncated multipliers, squarers and cubers. Initial coefficient values are obtained using a ...
Assessment of codivergence of Mastreviruses with their plant hosts
(BioMed Central, 2008-12-18)
Background: Viruses that have spent most of their evolutionary time associated with a single host lineage should have sequences that reflect codivergence of virus and host. Several examples for RNA viruses of host-virus ...
Resistance of Spiroplasma citri lines to the virus SVTS2 is associated with integration of viral DNA sequences into host chromosomal and extrachromosomal DNA
(American Society for Microbiology, 1995-11)
Spiroplasmavirus SVTS2, isolated from Spiroplasma melliferum TS2, produces plaques when inoculated onto lawns of Spiroplasma citri M200H, a derivative of the type strain Maroc R8A2. S. citri strains MR2 and MR3, originally ...
First detection of Rickettsia typhi and Rickettsia felis in fleas collected from client-owned companion animals in the southern Great Plains
(Oxford University Press (OUP), 2017-03-25)
Flea-borne rickettsiosis occurs worldwide and includes a number of pathogens, namely, Rickettsia typhi and Rickettsia felis. Most studies in the United States have occurred in southern Texas and California where flea-borne ...
Null-homologous exotic surfaces in 4-manifolds
(2013-10-07)
In this paper we exhibit infinite families of embedded tori in 4-manifolds that are topologically isotopic but smoothly distinct. The interesting thing about these tori is that they are topologically trivial in the sense ...
