Reclassification of 11 Members of the Family Rhodobacteraceae at Genus and Species Levels and Proposal of Pseudogemmobacter hezensis sp. nov.

open access: yesFrontiers in Microbiology, 2022
A novel Gram-stain-negative, aerobic, motile bacterial strain, D13-10-4-6T, was isolated from the bark sample of Populus × euramericana. The strain could grow at 15–35°C, at pH 6–10 and in 0–4% (w/v) NaCl, and the strain tested positive for oxidase and ...

The QCD corrections to scalar top pair production in photon-photon collisions [PDF]

open access: yes, 1997
The complete QCD corrections to the scalar top quark pair production via $\gamma \gamma$ fusion in parent $e^{+}e^{-}$ collider are calculated in the Supersymmetric Model. The various origins of corrections are discussed.

The helicity amplitudes A$_{1/2}$ and A$_{3/2}$ for the D$_{13}(1520)$ resonance obtained from the $\vec{\gamma} \vec{p} \to p \pi^0$ reaction} [PDF]

open access: yes, 2002
The helicity dependence of the $\vec{\gamma} \vec{p} \to p \pi^0$ reaction has been measured for the first time in the photon energy range from 550 to 790 MeV.

Pi N -> Omega N in a Coupled-Channel Approach

open access: yes, 2001
We describe the pi N -> omega N cross section from threshold to a center of mass energy of 2 GeV in a unitary coupled-channel model and analyze it in terms of rescattering and resonance excitations.

Association between aspartic acid repeat polymorphism of the asporin gene and risk of knee osteoarthritis: A systematic review and meta-analysis

open access: yesActa Orthopaedica et Traumatologica Turcica, 2017
Objective: Studies have assessed the association between aspartic acid (D)-repeat polymorphism in the gene encoding Asporin (ASPN) and knee osteoarthritis (KOA) risk, but the results were inconclusive and contradictory.

Influence of early use of antimicrobial on the health and performance of Holstein calves in the first month of life [PDF]

open access: yesPesquisa Veterinária Brasileira, 2020
: The early use of antimicrobial therapy has been introduced in many farms to prevent diarrhea and respiratory disease in young calves; however, there is controversy about whether this practice has a beneficial effect on the health of these animals. This

Quark Model Study of The eta Photoproduction: Evidence for a New S11 Resonance?

open access: yes, 2001
An extensive and systematic study of the recent eta photoproduction data up to 1.2 GeV is presented within a chiral constituent quark model. A model embodying all known nucleonic resonances shows clear need for a yet undiscovered third S11 resonance in ...

Electroexcitation of nucleon resonances at Q^2=0.65 GeV/c^2 from a combined analysis of single- and double-pion electroproduction data

open access: yes, 2005
Data on single- and double-charged pion electroproduction off protons are successfully described in the second and third nucleon resonance regions with common N* photocouplings. The analysis was carried out using separate isobar models for both reactions.

Woman among women: Female agency in traditional Chinese households, circa 1947

open access: yesAsia and the Global Economy, 2022
There is a big debate on the level of present-day female agency within the household in China. Even though the two sides of the debate make implicit assumptions on historical agency, a direct link is rarely established as we lack information on ...

Electromagnetic properties of strange baryons in a relativistic quark model [PDF]

open access: yes, 2007
We present some of our results for the electromagnetic properties of excited Σ hyperons, computed within the framework of the Bonn constituent-quark model, which is based on the Bethe-Salpeter approach.
