Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)

Direct and indirect effects of native and invasive plants on mosquito ecology
No full textContainer-breeding mosquitoes (Diptera: Culicidae), including the vectors of human and wildlife pathogens, interact with terrestrial plants throughout their life cycles. Inputs of leaf detritus into the aquatic habitat provide an energy base for developing larvae, and plants mediate the distribution of adult mosquitoes by influencing microclimate conditions, supplying sugar-feeding sources, and altering communities of wildlife blood-meal hosts. This dissertation examines direct and indirect effects of understory shrubs, including species both native and invasive to North America, on the ecology of Culex pipiens, an important vector of West Nile virus in the northeastern and midwestern United States. Laboratory and field bioassays demonstrated that leaf detritus from different plant species in the aquatic environment alter two key components of mosquito production (i.e., oviposition site selection and adult emergence) via the abundance and composition of bacterial flora that form on different leaf species as they decompose. In particular, an invasive plant (Lonicera maackii, Amur honeysuckle) yielded high oviposition and adult emergence rates, while in contrast, a native plant (Rubus allegheniensis, common blackberry) was identified to function as an ecological trap for Cx. pipiens, attracting gravid females to oviposit and yet deleterious to larvae yielding low emergence rates. Subsequent laboratory bioassays in which first instar larvae were exposed to mixtures of leaves from different plant species revealed that while leaf resource diversity generally yields an increase in Cx. pipiens adult emergence rates, addition of high-quality resources is not sufficient to offset the deleterious effect of R. allegheniensis leaves. I then explored two integrated vector management applications of these findings. First, a field experiment demonstrated the feasibility of exploiting a naturally-occurring ecological trap (R. allegheniensis leaves) and an artificial ecological trap (L. maackii leaves mixed with Bacillus thuringiensis var. israelensis larvicide) for attract-and-kill mosquito control in storm water catch basins, in which gravid females are lured to oviposit in a low-quality environment. This result provides experimental proof of concept for a novel integrated vector management tool that may enhance the effectiveness and sustainability of existing mosquito abatement strategies with minimal non-target effects and reduced potential to select for insecticide resistance. A second field experiment showed that removal of L. maackii decreases abundance of adult Culex spp. mosquitoes in forest fragments within a residential neighborhood. The mechanisms underlying this reduction in mosquito abundance most likely include effects of L. maackii removal on microclimate conditions and the availability of avian blood-meal hosts. Collectively, these studies reveal multiple ecological pathways by which terrestrial plants interact with, and alter the abundance, distribution, and life history characteristics of mosquitoes, and suggest landscape modification strategies that may be used to manage an important disease vector species in residential ecosystems.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-05-01The student, Allison Gardner, accepted the attached license on 2016-04-15 at 15:02.The student, Allison Gardner, submitted this Dissertation for approval on 2016-04-15 at 15:06.This Dissertation was approved for publication on 2016-04-20 at 10:19.DSpace SAF Submission Ingestion Package generated from Vireo submission #9240 on 2016-07-07 at 13:49:21Made available in DSpace on 2016-07-07T20:27:24Z (GMT).

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Comparative genomics of Shiga toxin encoding bacteriophages
No full textBackground
Stx bacteriophages are responsible for driving the dissemination of Stx toxin genes (stx) across their bacterial host range. Lysogens carrying Stx phages can cause severe, lifethreatening disease and Stx toxin is an integral virulence factor. The Stx-bacteriophage vB_EcoP-24B, commonly referred to as 24B, is capable of multiply infecting a single bacterial host cell at a high frequency, with secondary infection increasing the rate at which subsequent bacteriophage infections can occur. This is biologically unusual, therefore determining the genomic content and context of 24B compared to other lambdoid Stx phages is important to understanding the factors controlling this phenomenon and determining whether they occur in other Stx phages.
Results
The genome of the Stx2 encoding phage, 24B was sequenced and annotated. The genomic organisation and general features are similar to other sequenced Stx bacteriophages induced from Enterohaemorrhagic Escherichia coli (EHEC), however 24B possesses significant regions of heterogeneity, with implications for phage biology and behaviour. The 24B genome was compared to other sequenced Stx phages and the archetypal lambdoid phage, lambda, using the Circos genome comparison tool and a PCR-based multi-loci comparison system.
Conclusions
The data support the hypothesis that Stx phages are mosaic, and recombination events between the host, phages and their remnants within the same infected bacterial cell will continue to drive the evolution of Stx phage variants and the subsequent dissemination of shigatoxigenic potentia
