Materialwissenschaft und Werkstofftechnik, Volume 55, Issue 6, Page 733-750, June 2024.Effect of induction hardening on the corrosion‐fatigue strength of the wheelsetshaft material EA4T (25CrMo4+quenched and tempered) was investigated. Hardening parameter was indentified and optimized for slightly notched specimen. Moreover the electrochemical and fatigue tests were carried out for initial and hardened state.

CUDB: An improved decomposition model for orthogonal pseudo-polyhedra [PDF]
, 2011 We present a new decomposition model for Orthogonal Pseudo-Polyhedra (OPP): the Compact Union of Disjoint Boxes. This model is an improved version of the Ordered Union of Disjoint Boxes model.

Dynamic facial expression recognition with pseudo‐label guided multi‐modal pre‐training
IET Computer Vision, Volume 18, Issue 1, Page 33-45, February 2024.To reduce the dependency on expensive manual annotations for the dynamic expression recognition (DER) task, the authors propose a multi‐modal pre‐training method with a pseudo‐label guidance mechanism to make full use of unlabelled video data for learning informative representations of facial expressions, and achieve state‐of‐the‐art performance on the

Fire‐Induced Carbon Loss and Tree Mortality in Siberian Larch Forests
Geophysical Research Letters, Volume 51, Issue 1, 16 January 2024.Abstract Climate change is intensifying the fire regime across Siberia, with the potential to alter carbon combustion and post‐fire carbon re‐accumulation trajectories. Few field‐based estimates of fire severity (e.g., carbon combustion and tree mortality) exist in Siberian larch forests (Larix spp.), which limits our ability to project how an ...
