Oikos, EarlyView.Most insect pollinators are ectothermic and rely on external heat sources for temperature regulation. Forests, with their diverse canopy structures and sunlight penetration levels, create a mosaic of microclimates influencing these insects' behaviour.

Systematic Parameter Selection for Short Fiber Polymer Composite Direct Fiber Simulation
Polymer Composites, EarlyView.Interactions of individually simulated fibers are systematically calibrated such that their orientation history agrees with the results from analytical orientation models. ABSTRACT The orientation of fibers in short discontinuous fiber reinforced polymer composites is a critical factor in determining final mechanical and thermal properties.

Polymer Engineering &Science, EarlyView.Study on transient parison formation at various strokes during extrusion of Newtonian and viscoelastic fluids. In the presence of an offset between the mandrel and the bushing, Newtonian fluids exhibit a reduction in extrudate diameter, whereas viscoelastic fluids display diameter swelling only at flow rates exceeding a critical threshold.

Polymer Engineering &Science, EarlyView.We present the Moving Least‐Squares Aided Finite Element Method (MLS‐FEM) as a robust approach to evaluate flow fields in polymer mixers. Using a fixed background mesh that is independent of rotor shape and motion, MLS‐FEM captures distributive and dispersive mixing without the need for mesh regeneration.

Progress in Photovoltaics: Research and Applications, EarlyView.This work deals with basic interactions of additives during the crosslinking process of ethylene‐vinyl acetate copolymer (EVA) at different lamination temperatures. The influence of the used contents of crosslinking peroxides and crosslinking accelerators on the achieved gel content was comprehensively investigated.
