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 ...
On knot complements that decompose into regular ideal dodecahedra
(2012-09-05)
Aitchison and Rubinstein constructed two knot complements that can be decomposed into two regular ideal dodecahedra. This paper shows that these knot complements are the only knot complements that decompose into n regular ...
Novel high-rank phylogenetic lineages within a sulfur spring (Zodletone Spring, Oklahoma), revealed using a combined pyrosequencing-Sanger approach
(American Society for Microbiology, 2012-04-15)
The utilization of high-throughput sequencing technologies in 16S rRNA gene-based diversity surveys has indicated that within most ecosystems, a significant fraction of the community could not be assigned to known microbial ...
Antiretroviral therapy perceived efficacy and risky sexual behaviors: Evidence from Mozambique
(University of Chicago Press, 2012-10)
This paper studies the effect of increased access to antiretroviral therapy (ART) for AIDS on self-reported risky sexual behavior, using data collected in Mozambique in 2007 and 2008. The survey sampled both households ...
Impact of climate trends on tick-borne pathogen transmission
(Frontiers Media, 2012-03-27)
Recent advances in climate research together with a better understanding of tick-pathogen interactions, the distribution of ticks and the diagnosis of tick-borne pathogens raise questions about the impact of environmental ...
Two structurally discrete GH7-cellobiohydrolases compete for the same cellulosic substrate fiber
(BioMed Central, 2012-04-11)
Background: Cellulose consisting of arrays of linear beta-1,4 linked glucans, is the most abundant carbon-containing polymer present in biomass. Recalcitrance of crystalline cellulose towards enzymatic degradation is widely ...
Support Vector Machine based method to distinguish proteobacterial proteins from eukaryotic plant proteins
(BioMed Central, 2012-09-11)
Background: Members of the phylum Proteobacteria are most prominent among bacteria causing plant diseases that result in a diminution of the quantity and quality of food produced by agriculture. To ameliorate these losses, ...
Sigma factor n, liaison to an ntrC and rpoS dependent regulatory pathway controlling acid resistance and the LEE in enterohemorrhagic Escherichia coli
(Public Library of Science (PLoS), 2012)
Enterohemorrhagic Escherichia coli (EHEC) is dependent on acid resistance for gastric passage and low oral infectious dose, and the locus of enterocyte effacement (LEE) for intestinal colonization. Mutation of rpoN, encoding ...
Limits on anomalous trilinear gauge boson couplings from WW, WZ and Wgamma production in pp[over ¯] collisions at √s=1.96 TeV
(2012-10-26)
We present searches for the anomalous γWW and ZWW trilinear gauge boson couplings from WW and WZ production using lepton plus dijet final states and a combination with results from Wγ, WW, and WZ production with leptonic ...
Electromagnetically induced transparency in terahertz plasmonic metamaterials via dual excitation pathways of the dark mode
(AIP Publishing, 2012-03-26)
We observe the excitation and tuning of electromagnetically induced transparency (EIT) by the interference between different excitation pathways of the dark mode in a planar terahertz metamaterial. The EIT unit cell consists ...
