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.

Summary: observations of stellar halos
, 2019 This presentation summarizes a (biased) selection of results and discussions presented during the Sexten 2019 workshop "Light in the suburbs: structure and chemodynamics of galaxy halos" based on observations. Over the past decade observations of stellar

A search for the most massive galaxies: double trouble? [PDF]
, 2005 We describe the results of a search for galaxies with large ({approx}> 350 kms{sup -1}) velocity dispersions. The largest systems we have found appear to be the extremes of the early-type galaxy population: compared to other galaxies with similar ...

The Impact of Galaxy-halo Size Relations on Galaxy Clustering Signals
The Open Journal of AstrophysicsGalaxies come in different sizes and morphologies, and these differences are thought to correlate with properties of their underlying dark matter halos.

Formation and Assembly History of Stellar Components in Galaxies as a Function of Stellar and Halo Mass [PDF]
The Astrophysical Journal, 2017 Abstract Galaxy mass assembly is an end product of structure formation in the ΛCDM cosmology. As an extension of Lee & Yi, we investigate the assembly history of stellar components in galaxies as a function of halo environments and stellar mass using semi-analytic approaches.

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 ...

Galaxy morphology and the stellar-halo mass relation
, 2020 We use data from the SDSS DR7 and visual classifications of morphology from the Galaxy Zoo project to show that the scatter in the stellar-halo mass relation correlates with galaxy morphology, such that more massive galaxies at fixed halo mass are mostly spirals. We obtain this same correlation in galaxies from the EAGLE simulation.

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.

Detection of Accretion Shelves Out to the Virial Radius of a Low-mass Galaxy with JWST
The Astrophysical JournalWe report the serendipitous discovery of an extended stellar halo surrounding the low-mass galaxy Ark 227 ( M _* = 5 × 10 ^9 M _⊙ ; d = 35 Mpc) in deep JWST NIRCam imaging from the Blue Jay Survey.
