Dual Modality Semiconducting Polymer Nanoparticles for Use in Optical and Magnetic Resonance Imaging

open access: yesAdvanced NanoBiomed Research, EarlyView.
Well‐defined dual‐modality semiconducting polymer nanoparticles composed of red‐emitting conjugated polymers functionalized with novel gadolinium‐based contrast agents have been prepared. The assemblies show a greatly enhanced relaxivity performance compared to the clinical standard, Dotarem, while offering ultrabright fluorescence, ideal for optical ...

Logarithmic and Strong Coupling Models in Weyl‐Type f(Q,T)$f(Q,T)$ Gravity

open access: yesAnnalen der Physik, EarlyView.
This work explores Weyl‐type f(Q,T) gravity using recent observational datasets — CC, Pantheon+, Union 3.0, and DESI DR2. Through MCMC analysis of logarithmic and strong coupling models, the study reveals a transition from deceleration to acceleration, quintessence‐to‐phantom dynamics, and late‐time consistency with LCDM, offering a geometry‐driven ...

Polyethylene Melt Rupture and Slip in Simple Shear: A Visual and Mechanistic Study

open access: yesJournal of Applied Polymer Science, EarlyView.
Slip velocity transient curve (left) with images of the specimen at different times during a simple shear experiment. On the right, schematics illustrate the sample and its side view before and after simple shear. ABSTRACT Melt rupture of a bimodal molecular weight distribution polyethylene is studied under simple shear via flow visualization ...

A global overview of anatomical science education and its present and future role in biomedical curricula

open access: yesAnatomical Sciences Education, EarlyView.
How the anatomical sciences are taught worldwide is constantly changing. Common themes are a reduction of teaching time and the inclusion of e‐learning and new pedagogical approaches. Although there is a common direction of change, where different global regions place along that trajectory often correlates with their economic status.

“You're this person who's providing light”: Embodied responses to information loss and transition within LGBTQIA+ communities

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract This paper reports on findings from 15 semi‐structured interviews with LGBTQIA+ individuals within the United States who have experienced the loss of one or more LGBTQIA+ information spaces. The paper specifically focuses on how such losses occurred and the information transitions experienced by the participants in response to this loss ...
