Background: Measurements of polarization observables for the reactions $\stackrel{P\vec}{\ensuremath{\gamma}}p\ensuremath{\rightarrow}{K}^{+}\mathrm{\ensuremath{\Lambda}}$ and $\stackrel{P\vec}{\ensuremath{\gamma}}p\ensuremath{\rightarrow}{K}^{+}{\mathrm{\ensuremath{\Sigma}}}^{0}$ have been performed. This is part a program measurements designed to study spectrum baryon resonances in particular, nonperturbative QCD general.Purpose: The accurate measurement several provides tight constraints...
The mechanisms that underpin the formation, growth and composition of otoliths, biomineralized stones in inner ear fish, are largely unknown, as only a few fish proteins have been reported. Using partial transcriptome for black bream (Acanthopagrus butcheri), conjunction with proteomic data, we discovered hundreds previously unknown otolith. This allowed us to develop hypotheses explain inorganic material supply daily formation bands. We further identified likely protein mediator crystal...
A determination of the spin and parity Λ(1405) is presented using photoproduction data from CLAS detector at Jefferson Lab. The reaction γ+p→K++Λ(1405) analyzed in decay channel Λ(1405)→Σ++π−, where distribution to Σ+π− variation Σ+ polarization with respect direction determines parity. produced, energy range 2.55<W<2.85 GeV for 0.6<cosθc.m.K+<0.9, P=0.45±0.02(stat)±0.07(syst). analysis shows that decays are S wave, polarized such has spin-parity JP=12−, as expected by most theories.Received...

Data collected nearly complete coverage azimuthal polar angles $n{\ensuremath{\pi}}^{+}$ center-of-mass system....
Gut dysbiosis can induce chronic inflammation and contribute to atherosclerosis vascular calcification. The aortic arch calcification (AoAC) score is a simple, noninvasive, semiquantitative assessment tool evaluate on chest radiographs. Few studies have discussed the relationship between gut microbiota AoAC. Therefore, this study aimed compare composition patients with diseases high or low AoAC scores. A total of 186 (118 males 68 females) diseases, including diabetes mellitus (80.6%),...
We have measured the moment ALUsinϕ corresponding to polarized electron beam-spin asymmetry in semi-inclusive deep inelastic scattering. is a twist-3 quantity providing information about quark-gluon correlations. Data were taken with CLAS Spectrometer at Jefferson Lab using 5.498 GeV longitudinally beam and an unpolarized liquid hydrogen target. All three pion channels (π+, π0 π−) simultaneously over large range of kinematics within virtuality Q2≈ 1.0–4.5 GeV2. The observable was better than...
We report the first beam-target double-polarization asymmetries in γ+n(p)→π^{-}+p(p) reaction spanning nucleon resonance region from invariant mass W=1500 to 2300 MeV. Circularly polarized photons and longitudinally deuterons solid hydrogen deuteride (HD) have been used with CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab. The exclusive final state has extracted using three very different analyses that show excellent agreement, these deduce E polarization observable for an...
The reaction ⁎γp→K⁎+Λ was measured using the CLAS detector for photon energies between threshold and 3.9 GeV at Thomas Jefferson National Accelerator Facility. For first time, spin-density matrix elements have been extracted this reaction. Differential cross sections, spin density elements, Λ recoil polarization are compared with theoretical predictions BnGa partial wave analysis. main result is evidence significant contributions from N(1895)1/2− N(2100)1/2+ to Branching ratios decays into...
Understanding how animals interact with their environment is a fundamental ecological question important implications for conservation and management. The relationships between habitat, however, can be scale-dependent. If ecologists work at suboptimal spatial scales, they will gain an incomplete picture of respond to the landscape. Identifying scale which animal-landscape are strongest (the "scale effect") improve our ability better plan management activities. Several recent studies have...
Abstract Many animals improve their foraging success by producing signals that exploit the sensory biases of potential prey, but specific properties make these traps effective remain unclear. We combine field experiments with phylogenetic comparative analyses to investigate visual luring different signal designs in web‐building spiders. Our used cardboard spider models examine effects area colour patches, and pattern on colourful giant wood spider, Nephila pilipes . These revealed both...
Abstract Aim We assessed the population genetic structure of kleptoparasitic spider Argyrodes bonadea across Southwestern Pacific islands. Our aim is to evaluate impact overseas distances and, in particular, Kerama gap, as potential drivers differentiation. If no relationship exists, then we assume dispersal following adaptive change alternative non‐vicariant mechanism that generates divergence. Location Islands. Taxon bonadea. Methods used mitochondrial Cytochrome Oxidase 1 (CO1) gene...
Abstract Symbiotic relationships shape ecological communities and often involve more than two species. Yet few experimental studies examine the impact of symbioses involving three species, particularly any mediating role third parties, none predators. We investigated experimentally synergistic antagonistic fitness effects symbiotic spider predators across a broad latitudinal range different species combinations. The three‐dimensional web complex Cyrtophora spiders is habitat patch to...
We have measured the induced polarization of ${\Lambda}(1116)$ in reaction $ep\rightarrow e'K^+{\Lambda}$, detecting scattered $e'$ and $K^+$ final state along with proton from decay $\Lambda\rightarrow p\pi^-$.The present study used CEBAF Large Acceptance Spectrometer (CLAS), which allowed for a large kinematic acceptance invariant energy $W$ ($1.6\leq W \leq 2.7$ GeV) covered full range kaon production angle at an average momentum transfer $Q^2=1.90$ GeV$^2$.In this experiment 5.50 GeV...
We measured the ratios of electroproduction cross-sections from a proton target for three exclusive meson-baryon final states: $\Lambda K^+$, $p\pi^0$, and $n\pi^+$, with CLAS detector at Jefferson Lab. Using simple model quark hadronization we extract q-qbar creation probabilities first time in two-body production, which only single pair is created. observe sizable suppression strange quark-antiquark pairs compared to non-strange pairs, similar that seen high-energy production.
Abstract Body coloration serves a variety of purposes in animals. Diurnal and nocturnal predators such as spiders may use their body to lure prey. We predicted here that the white patches on forelegs females semi‐aquatic spider Dolomedes raptor prey, explaining why they are primarily displayed when forages along water edge. To test our prediction, we developed color vision model assessing whether visible pygmy grasshoppers, spider's primary conducted field experiment using cardboard dummies...
Rheumatoid arthritis (RA) and periodontitis are suggested to be closely linked based on microbial dysbiosis, but limited subgingival bacteria have been proven in the pathogenesis of RA. We enrolled 30 RA patients 25 controls divided them into three groups with matched age, gender, diabetes statuses: group AM (all participants), PD (periodontally diseased), PH healthy). Their composition was determined by V3-V4 16S rRNA gene sequencing. Significant differences clustering between were observed...
