Crafting agency in a host community: Accessing and participating in the English higher education sector by Ukrainian refugees

British Educational Research Journal, EarlyView.
Abstract Following Russia's launch of a full‐scale war against Ukraine in 2022, scholarship has not yet addressed how Ukrainian refugees in England have been navigating the challenges of developing their agency in pursuing opportunities to participate in the higher education (HE) sector.

Mapping Observations of Peptide-like Molecules around Sagittarius B2

The Astrophysical Journal
Peptide-like molecules, which have a close connection with the origin of life, have been detected in the Universe. Mapping observations of HCONH _2 and CH _3 CONH _2 , two of the simplest peptide-like molecules, are performed toward the Sagittarius B2 ...

Signatures of minor mergers in the Milky Way disc I: The SEGUE stellar sample

, 2012
It is now known that minor mergers are capable of creating structure in the phase-space distribution of their host galaxy's disc. In order to search for such imprints in the Milky Way, we analyse the SEGUE F/G-dwarf and the Schuster et al. (2006) stellar

Dynamical Inference from Polarized Light Curves of Sagittarius A*

The Astrophysical Journal
Polarimetric light curves of Sagittarius A* (Sgr A*) sometimes exhibit loops in the Stokes Q and U plane over time, often interpreted as orbiting hotspot motion. In this work, we apply the differential geometry of planar curves to develop a new technique

Protein‐Functionalized Separator for Suppression of Shuttle Effect and Regulation of Lithium Deposition in Li–S Batteries

Battery Energy, EarlyView.
This study demonstrates the enhancement of Li‐S battery performance by functionalizing separators with a natural protein and a polar polymer. The modified separator effectively suppresses polysulfide shuttling and regulates lithium ion deposition. This design enables stable cycling, providing a promising strategy for advancing high‐performance Li‐S ...
