Effects of Dietary Mannan Oligosaccharides on Growth, Disease Resistance, and Gut Microbiota in Zebrafish

Animal Research and One Health, EarlyView.
Supplementation with mannan oligosaccharides (MOS) enhances growth, disease resistance, antioxidant capacity, and gut microbiota diversity while suppressing inflammation, apoptosis, and strengthening intestinal barrier integrity in zebrafish challenged with LPS or DSS.

The Next Generation Virgo Cluster Survey (NGVS). XIV. The Discovery of Low-mass Galaxies and a New Galaxy Catalog in the Core of the Virgo Cluster^∗

The Astrophysical Journal, 2020
Abstract The Next Generation Virgo Cluster Survey (NGVS) was designed to provide a deep census of baryonic structures in the Virgo cluster. The survey covers the 104 deg2 area from the core of Virgo out to one virial radius, in the u*griz bandpasses, to a point-source depth of g ∼ 25.9 mag (10σ) and a single pixel surface brightness ...

Influence of Dynamical Friction on the Unstable Manifolds of Lagrange Points in Barred Galaxies

Astronomische Nachrichten, EarlyView.
ABSTRACT Some time ago the idea has been proposed that rings and spirals in barred galaxies are shaped by the unstable manifolds of the Lagrange points sitting near the ends of the bar. The topic of the present article is an investigation of whether the numerical support for this suggestion can be improved by the inclusion of dynamical friction into ...

Anterior Drawer Maneuver to Access Knee Posteromedial Compartment

Arthroscopy Techniques, EarlyView.
Abstract Over the years, diagnostic arthroscopy has been the key to accurately diagnosing lesions in the knee. However, accessing the posterior compartment of the knee remains a challenge for upcoming arthroscopy surgeons. Gillquist was the first surgeon to publish a technique for accessing the posteromedial compartment in 1979, following which several

Form flows function: Learner‐centered game Re‐design in a STEM classroom

British Educational Research Journal, EarlyView.
Abstract Re‐designing games facilitates interest‐driven learning and immerses learners in systems thinking. However, there are limited studies exploring how the form and function of tabletop games influence learners' design decisions and learning experiences. To address this gap, we conducted a mixed‐methods study in a STEM classroom in western Canada.

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

Deep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

A Generative Model for Realistic Galaxy Cluster X-Ray Morphologies

The Astrophysical Journal
Abstract The X-ray morphologies of clusters of galaxies display significant variations, reflecting their dynamical histories and the nonlinear dependence of X-ray emissivity on the density of the intracluster gas. Qualitative and quantitative assessments of X-ray morphology have long been considered a proxy for determining whether ...

Gas, Iron, and Gravitational Mass in Galaxy Clusters: The General Lack of Cluster Evolution at z < 1.0 [PDF]

Publications of the Astronomical Society of Japan, 2000
We have analyzed the ASCA data of 29 nearby clusters of galaxies systematically, and obtained temperatures, iron abundances, and X-ray luminosities of their intracluster medium (ICM). We also estimated the ICM mass using the β model, and then evaluated the iron mass contained in the ICM and derived the total gravitating mass. This gives the largest and

Cis–Trans Rotational Isomerism of Formic Acid, Sulfur, and Selenium Analogues and Their Dimers: Chemical Kinetics Under Interstellar Conditions

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT We present chemical kinetic rate constants for the cis to trans isomerisation or rotamerization of monomeric seleno‐, thio‐, and formic acids and that of three of their dimeric species, based on variational transition state theory and multidimensional tunneling calculations in the gas‐phase, from 10 K to 300 K. These provide, firstly, reliable
