Thixotropic and Mechanical Behavior of MgO–SiO2 Pastes Incorporating Rice Husk Ash for Extrusion‐Based 3D Printing

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT Rice husk ash (RHA) is an agricultural by‐product that can replace microsilica (MS) as a suitable silica source in MgO–SiO2 cement mixes, offering low‐carbon benefits. This study investigated the 3D printing properties, including thixotropy and hardened mechanical properties, of the MgO–SiO2 system formed by partial and total replacement of MS

Who Gives Feedback Matters: Student Biases Towards Human and AI‐Generated Formative Feedback

open access: yesJournal of Computer Assisted Learning, Volume 42, Issue 1, February 2026.
ABSTRACT Background Feedback is essential for learning, helping individuals understand and improve their performance. However, providing timely, personalised feedback in higher education is challenging. Generative AI offers a scalable solution, yet little is known about students' biases towards AI‐generated feedback.

Technology on Snow and Ice: Innovation, Monitoring, and Performance for the Olympic Winter Games Milano Cortina 2026

open access: yesScandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 2, February 2026.
ABSTRACT Elite performance in Olympic winter sports depends on the interplay among the athlete, equipment, and the snow or ice. This naturally evolves with temperature, humidity, wind, preparation, and contact between the equipment and its surface. Together, these factors continuously rebalance the forces of gravity, aerodynamic drag, and friction ...

On the topological ranks of Banach ∗$^*$‐algebras associated with groups of subexponential growth

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 2, February 2026.
Abstract Let G$G$ be a group of subexponential growth and C→qG$\mathcal C\overset{q}{\rightarrow }G$ a Fell bundle. We show that any Banach ∗$^*$‐algebra that sits between the associated ℓ1$\ell ^1$‐algebra ℓ1(G|C)$\ell ^1(G\,\vert \,\mathcal C)$ and its C∗$C^*$‐envelope has the same topological stable rank and real rank as ℓ1(G|C)$\ell ^1(G\,\vert ...
