Polymer Composites, EarlyView.Thermal Aging and Tribological Tests of Additive Manufactured PLA Composites. ABSTRACT This study focuses on the additive manufacturing of pure polylactic acid (PLA) specimens and milled glass fiber (GF)‐filled PLA composites under thermal cycling aging and wear tests. Wear tracks have been analyzed via 3D optical profiling and SEM imaging.

Fusion Energy and Tritium Fuel Cycle: Hydrogen Isotope Separation Technologies and Sorbent Materials
Small Methods, EarlyView.This review surveys sorbent‐based materials for hydrogen isotope separation, a key challenge in fusion fuel processing. Different types of adsorbents are compared in terms of selectivity, kinetics, and operational practicality. Limitations of cryogenic operation and tritium compatibility are highlighted, providing guidance toward efficient, low tritium

Fused Collapsing for Wide BVH Construction
Computer Graphics Forum, EarlyView.Abstract We propose a novel approach for constructing wide bounding volume hierarchies on the GPU by integrating a simple bottom‐up collapsing procedure within an existing binary bottom‐up BVH builder. Our approach directly constructs a wide BVH without traversing a temporary binary BVH as done by previous approaches and achieves 1.4 – 1.6 × lower ...

UBVH: Unified Bounding Volume and Scene Geometry Representation for Ray Tracing
Computer Graphics Forum, EarlyView.Abstract Bounding volume hierarchies (BVHs) are currently the most common data structure used to accelerate ray tracing. The existing BVH methods distinguish between the bounding volume representation associated with the interior BVH nodes and the scene geometry representation associated with leaf nodes.

Mitogenome structure and phylogenomics of the order Thoreales (Nemaliophycidae, Rhodophyta)
Journal of Phycology, EarlyView.Abstract Organelle genomes offer a powerful tool for red algal evolutionary studies. Although the number of Rhodophyta genomes has increased substantially over the past 2 decades, only two mitochondrial genomes have been reported for the red algal order Thoreales.
