Social status and previous experience in the group as predictors of welfare of sows housed in large semi-static groups.

open access: yesPLoS ONE, 2021
Mixing gestating sows implies hierarchy formation and has detrimental consequences on welfare. The effects of social stress on the most vulnerable individuals may be underestimated and it is therefore important to evaluate welfare between individuals ...

Reanalysis of the $Y(3940)$, $Y(4140)$, $Z_c(4020)$, $Z_c(4025)$ and $Z_b(10650)$ as molecular states with QCD sum rules [PDF]

open access: yes, 2014
In this article, we calculate the contributions of the vacuum condensates up to dimension-10 in the operator product expansion, and study the $J^{PC}=0^{++}$, $1^{+-}$, $2^{++}$ $D^*\bar{D}^*$, $D_s^*\bar{D}_s^*$, $B^*\bar{B}^*$, $B_s^*\bar{B}_s ...

Biomechanical Characteristics of Osteoporotic Fracture Healing in Ovariectomized Rats: A Systematic Review.

open access: yesPLoS ONE, 2016
Biomechanical tests are widely used in animal studies on osteoporotic fracture healing. However, the biomechanical recovery process is still unknown, leading to difficulty in choosing time points for biomechanical tests and in correctly assessing ...

Linearly Polarized Gluons and the Higgs Transverse Momentum Distribution [PDF]

open access: yes, 2012
We study how gluons carrying linear polarization inside an unpolarized hadron contribute to the transverse momentum distribution of Higgs bosons produced in hadronic collisions.

Causes for the Change Orders in Road Construction: Reviewed from Owner

open access: yesCommunications, 2022
Changes in road construction are affected by the owner and contractor at the beginning, middle, or end of the project. This study aims to determine the ranking of the factors that cause change orders for road construction from the owner's point of view ...

Simulation of bridge pier scour depth base on geometric characteristics and field data using support vector machine algorithm [PDF]

open access: yesJournal of Applied Research in Water and Wastewater, 2020
In this paper, two groups of datasets including Froehlich (1988) and USGS were implemented to simulate scour depth for bridge piers of three shapes (circular, sharp-nose and rectangular) using support vector machine (SVM) algorithm.

Interpretations and Implications of the Top Quark Rapidity Asymmetries $A_{FB}^t$ and $A_{FB}^{\ell}$

open access: yes, 2013
Forward-backward asymmetries $A_{FB}^t$ and $A_{FB}^\ell$ are observed in the top quark $t$ rapidity distribution and in the rapidity distribution of charged leptons $\ell$ from top quark decay at the Tevatron proton-antiproton collider, and a charge ...

$\pi^0\to\gamma^*\gamma$ transition form factor within Light Front Quark Model

open access: yes, 2012
We study the transition form factor of $\pi^0\to\gamma^* \gamma$ as a function of the momentum transfer $Q^2$ within the light-front quark model (LFQM). We compare our result with the experimental data by BaBar as well as other calculations based on the ...

Quantum refinement with electron diffraction and X‐ray free‐electron laser data: comparative study of ribonucleotide reductase dimetal site

open access: yesJournal of Applied Crystallography, EarlyView.
For the first time quantum refinement has been performed with X‐ray free‐electron laser and microcrystal electron diffraction data for the dinuclear iron site in the R2a protein of ribonucleotide reductase. The method is shown to work well and can be used to determine the protonation state of the bridging solvent molecule and deduce photoreduction in ...

Downstream fining trends of gravel bar sediments: a case study of Czech Carpathian rivers

open access: yesActa Universitatis Carolinae Geographica, 2020
This study examines downstream grain-size trends in gravel bars, a typical feature of natural gravel-bed rivers, from two neighbouring heavily channelized rivers: the Lubina River and the Ondřejnice River draining the Czech part of the Outer Western ...
