Multiscale mechanistic modelling of heterogeneity in cardiac sub‐cellular calcium handling accounting for variable t‐system density

The Journal of Physiology, EarlyView.
Abstract figure legend Illustration of spatial calcium dynamics (left panels) and the state cycle approximation (middle panel) that enables reduced simulation of spatially dependent dynamics without explicit description of space (right panels). The selected example here illustrates a spontaneous calcium wave, showing temporal snapshots of local calcium

Stochastic Gradient Descent in High Dimensions for Multi‐Spiked Tensor PCA

Communications on Pure and Applied Mathematics, Volume 79, Issue 10, Page 2291-2369, October 2026.
ABSTRACT We study the high‐dimensional dynamics of online stochastic gradient descent (SGD) for the multi‐spiked tensor model. This multi‐index model arises from the tensor principal component analysis (PCA) problem with multiple spikes, where the goal is to estimate the unknown signal vectors within the N$N$‐dimensional unit sphere through maximum ...

Emergent Learner Agency in Implicit Human–AI Collaboration: How Supportive and Contrarian AI Personas Reshape Interaction

Journal of Computer Assisted Learning, Volume 42, Issue 5, October 2026.
ABSTRACT Background As agentic artificial intelligence (AI) systems move beyond tool‐like support toward more autonomous, team‐like roles, a central question concerns the extent to which such systems can meaningfully participate in collaborative learning.

Insight of Elementary Steps on the Polyethylene and Polypropylene Co‐Pyrolysis

Carbon and Hydrogen, Volume 28, Issue 3, Page 383-392, September 2026.
Pyrolysis of PP initiates first, accelerating PE cracking via secondary radical transfer, leading to n‐hydrocarbon yield enhancement. Py–GC/MS and nanoreactor computation are in agreement on the elementary step proposal. ABSTRACT Pyrolysis with gas chromatography & mass spectrometry (Py–GC/MS) technique was employed to analyze the yield variation of ...

Large Regional Variation in Global Impacts of Agriculture on Terrestrial Insects and Other Arthropods

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
We show that impacts of agriculture on arthropod biodiversity are notably less negative in Europe than in other regions, which we find is driven by a degraded baseline, a selection bias of reference sites, and novel species compositions in agriculture that favour widespread habitat generalists and non‐native species.

Biogeographical Expansion and Integrative Taxonomic Confirmation of Cortinarius saniosus (Fr.) Fr. and C. desertorum (Velen.) G. Garnier in Anatolia

New Zealand Journal of Botany, Volume 64, Issue 3, September 2026.
Integrative morphological and ITS‐based phylogenetic analyses confirm the occurrence of Cortinarius saniosus and C. desertorum in the montane Pinus sylvestris forests of Eastern Anatolia, Türkiye. These records represent a significant southeastward expansion of the species’ documented, distributions and provide molecularly characterized material from ...

Regulating Reality: Exploring Synthetic Media Through Multistakeholder AI Governance

Policy &Internet, Volume 18, Issue 3, September 2026.
ABSTRACT Artificial intelligence's integration into daily life has brought with it a reckoning on the role such technology plays in society and the varied stakeholders who should shape its governance. This is particularly relevant for AI‐generated, or synthetic, media, an emergent visual technology impacting perceptions of media as records of reality ...

Redefining Optimal Coverage Path Planning for FLS‐Equipped AUVs With Deep Reinforcement Learning

Journal of Field Robotics, Volume 43, Issue 6, Page 3617-3632, September 2026.
ABSTRACT Autonomous Underwater Vehicles (AUVs) have emerged as indispensable tools for a variety of subsea tasks, from habitat monitoring and seabed mapping to infrastructure inspection and mine countermeasures. A fundamental challenge in this field is Coverage Path Planning (CPP), the problem of ensuring complete and efficient area coverage.
