A Multiwavelength Investigation of Dust and Stellar Mass Distributions in Galaxies: Insights from High-resolution JWST Imaging

The Astrophysical Journal, 2023
We study the morphological properties of mid-infrared selected galaxies at 1.0 < z < 1.7 in the SMACS J0723.3-7327 cluster field to investigate the mechanisms of galaxy mass assembly and structural formation at cosmic noon.

Direct SMBH Formation Driven by Runaway Stellar Collisions in Globally Unstable Stellar Systems

Astronomische Nachrichten, EarlyView.
ABSTRACT The fueling problem addresses the ultimate fate of the reservoirs of gas and stars driven into the deepest gravitational potential wells of galaxies, thus it may contain the Universe's densest concentrations of gas and stars. This raises a key question: does the infalling material collapse directly into a supermassive black hole, or can it ...

Targeting Amastigote and Trypomastigote Phases: Multi‐Epitope Vaccine Strategy Against Trypanosoma cruzi

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Effective vaccines against Trypanosoma cruzi, the causative agent of Chagas disease, are urgently needed. Here, we report the design and in silico validation of a novel multiepitope vaccine construct targeting the key surface proteins ASP‐2 and gp82. Using a comprehensive immunoinformatics pipeline, we identified and selected 38 potent T‐cell (

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 ...

An Equilibrium Model of the Galaxy Determined by Element Abundance Gradients

The Astrophysical Journal
We present a method to determine the gravitational potential of the Milky Way from measurements of the locations, velocities, and element abundances of stars in the Galactic disk.

The edge of the Milky Way’s star-forming disc: Evidence from a ’U-shaped’ stellar age profile

Astronomy & Astrophysics
We leveraged reliable age and distance estimates from LAMOST-DR3 and APOGEE-DR17+AstroNN combined with Gaia data to perform a detailed analysis of the stellar age distribution in the Milky Way’s (MW) outer disc using giant stars. Selecting stars near the

Gut microbiota dysbiosis‐mediated gut NLRP3 inflammasome activation exacerbates corticospinal tract injury after intracerebral hemorrhage

Interdisciplinary Medicine, EarlyView.
Schematic depicting a gut‐brain pathway that exacerbates CST injury after ICH. Gut Microbiota Dysbiosis‐Mediated Gut NLRP3 Inflammasome Activation Exacerbates Corticospinal Tract Injury After Intracerebral Hemorrhage. Abstract Intracerebral hemorrhage (ICH) causes severe neurological deficits largely attributable to corticospinal tract (CST) injury ...

Understanding the Concept of Self‐Performed Ultrasound: A Scoping Review

Journal of Ultrasound in Medicine, EarlyView.
Self‐performed ultrasound is an emerging technology that facilitates adept self‐scans in untrained hands. Inspired by self‐performed imaging in space for more prompt diagnosis and therapy, it has the potential to accurately monitor chronic conditions remotely. However, the lack of supervision and physical restraints can hinder its usability.
