Dynamic Debt With Intensity‐Based Models
Journal 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

Journal 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
Journal 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

Portfolio Optimization for Pension Purposes: Literature Review
Journal of Economic Surveys, Volume 40, Issue 1, Page 45-72, February 2026.ABSTRACT This systematic review identifies persistent challenges and gaps in the literature on pension portfolio optimization models. We searched, selected, and critically analyzed 82 articles from three major academic databases published over the past decade to investigate the barriers to the effective implementation of these models.

Risk preference based option pricing in a fractional Brownian market [PDF]
We focus on a preference based approach when pricing options in a market driven by fractional Brownian motion. Within this framework we derive formulae for fractional European options using the traditional idea of conditional expectation.

Integrin‐Piezo1 Axis Drives ECM Remodeling and Invasion of 3D Breast Epithelium
Advanced Science, Volume 13, Issue 5, 27 January 2026.Mechanical stiffening of the extracellular matrix around mature mammary acini induces sequential remodeling phases. An early response disrupts the basement membrane and promotes fibronectin secretion, followed by delayed invasion with matrix reorganization and proliferation.
