Dynamic Debt With Intensity‐Based Models

open access: yesJournal of Futures Markets, Volume 46, Issue 2, Page 334-352, February 2026.
ABSTRACT This article proposes a dynamic debt model where the face value of debt can change. In particular, our dynamic debt setting allows debt changes ruled by intensity processes that are linked to the firm value through the correlation between the stochastic processes. Analytical solutions are obtained, and we extend the proposed dynamic debt model

Unconventional Secretion of Angiogenic Sonic Hedgehog–Containing Extra‐Large Extracellular Vesicles is Driven by PI3K–Rab18‐GDP Signalling

open access: yesJournal of Extracellular Biology, Volume 5, Issue 2, February 2026.
Human mesenchymal stem cells conditionally secrete sonic hedgehog (SHH)‐containing extra‐large extracellular vesicles (XLEVs) upon PI3K activation, which enriches the GDP‐bound form of Rab18. Rab18‐GDP drives perinuclear maturation and polarized vertical release of SHH‐XLEVs via Hsp90α‐ and nSMase2‐dependent mechanisms.

Haptic Experiences Shift Students' Representational Gestures and Knowledge Resources

open access: yesJournal of Research in Science Teaching, Volume 63, Issue 2, Page 138-160, February 2026.
ABSTRACT The present investigation adopts an embodied cognition perspective to characterize students' learning interactions between gesture and haptic experience. Haptic technologies have emerged as a promising approach to science learning because they can simulate physical forces that students would otherwise not experience. Student‐generated gestures
