Multi‐Horizon Active Layer Thickness Prediction Across Circum‐Arctic Permafrost Regions Using Geospatial Machine Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Accurately predicting active layer thickness (ALT) is critical for assessing permafrost stability and mitigating risks to Arctic infrastructure, ecosystems, and communities. However, large‐scale ALT prediction remains challenging due to limited in situ observations and high spatial variability in environmental drivers.

Damage Analysis of Third-Generation Advanced High-Strength Steel Based on the Gurson–Tvergaard–Needleman (GTN) Model

Metals, 2022
The third generation of advanced high-strength steels (AHSS) brought attention to the steel and automotive industries due to its good compromise between formability and production costs.

Proposal of determination method for the material parameters of the GTN model based on sensitivity analysis by the Monte Carlo method

Nihon Kikai Gakkai ronbunshu
Fracture analysis using damage mechanics models such as the GTN (Gurson-Tvergaard-Needleman) model is applied for the purpose of limit load or limit strain evaluation of structures.

Damage identification parameters of dual-phase 600–800 steels based on experimental void analysis and finite element simulations

Journal of Materials Research and Technology, 2019
In this work, the damage behavior of cold-rolled zinc-coated dual-phase steel sheets 600 and 800 grades was evaluated by means of standard uniaxial tensile testing, microstructural characterization and finite element modeling.

Ductile fracture simulations using a multi-surface coupled damage-plasticity model [PDF]

, 2017
In this paper, an isotropic porous metal plasticity model accounting for both void growth by diffuse plastic deformation and void ‘coalescence’ by localization of plastic flow in the inter-void ligaments is presented.

Multiple dietary supplements do not affect metabolic and cardio-vascular health [PDF]

, 2013
Dietary supplements are widely used for health purposes. However, little is known about the metabolic and cardiovascular effects of combinations of popular over-the-counter supplements, each of which has been shown to have anti-oxidant, anti-inflammatory

Telotristat ethyl affects tumour‐fibroblast crosstalk in small intestinal neuroendocrine tumours

Journal of Neuroendocrinology, Volume 37, Issue 11, November 2025.
Abstract Small intestinal neuroendocrine tumours (SI‐NETs) are associated with mesenteric fibrosis, which causes significant morbidity and mortality. Telotristat ethyl was developed to treat carcinoid syndrome in SI‐NET patients. Recent studies indicated telotristat ethyl could have anti‐tumour activity; however, the mechanism remains unclear.

Optimal control of single‐phase microgrid with photovoltaic and energy storage for improving operation performance and seamless state transition

Energy Conversion and Economics, Volume 6, Issue 5, Page 324-340, October 2025.
Abstract Under voltage sags, swells, stochastic load profiles and harmonic voltage distortion, conventional synchronisation mechanisms often fail to track the grid voltage immediately and accurately, leading to degraded control performance and potential power quality violations.
