Numerical Simulations of Very Low Velocity Impacts and Ignition of an Explosive Confined by a Thin Case

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 3, Page 446-455, March 2026.
A low‐speed impact (around one meter per second) of a metallic tip on an explosive confined by a thin plate is simulated. The heat due to friction between the tip and the plate and the one due to the deformation of the plate are not transfered to the ignited zone.

Rotor wake interactions with an obstacle on the ground [PDF]

, 2018
An investigation of the flow around an obstacle positioned within the wake of a rotor is described. A flow visualisation survey was performed using a smoke wand and particle image velocimetry, and surface pressure measurements on the obstacle were taken.

Capillary Dynamics Analysis of Millimetric Tubes for Anti‐Slip Surfaces: A Phase‐Field Based Finite Element Approach and Experimental Validation

Advanced Theory and Simulations, Volume 9, Issue 2, February 2026.
Phase‐field method based numerical modelling of the capillary rise in millimeter‐sized tubes, aiming for anti‐slip applications. The experimental validation was performed through capillary assays in polyethylene oxide (PEO) bulk modified polydimethylsiloxane (PDMS) channels.

The Critical Role of the Intermittent Two‐Phase Flow Topology on the Solute Dispersion in Partially Saturated Porous Media

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Intermittent flow is a widely recognized phenomenon across various fields, characterized by the spatial‐temporal fluctuations of the two‐phase topology. However, its implications for solute dispersion and mixing remain insufficiently understood.

An experimental study of bubble departure diameter in subcooled flow boiling including the effects of orientation angle, subcooling, mass flux, heat flux, and pressure [PDF]

, 2014
The effects of orientation angle, subcooling, heat flux, mass flux, and pressure on bubble departure diameter in the isolated bubble regime of subcooled flow boiling were studied by high-speed video in a two-phase flow loop that can accommodate a wide ...

Animal‐mediated seed dispersal: A review of study methods

Applications in Plant Sciences, Volume 14, Issue 1, January-February 2026.
Abstract By dispersing seeds, animals provide ecological functions critical for the ecology, evolution, and conservation of plants. We review quantitative and empirical approaches and emerging technologies to quantify processes and patterns of animal‐mediated seed dispersal (zoochory) across its phases: from predispersal to postdispersal.

Continuous sPatial‐temporal deformable image registration and 4D frame interpolation

Medical Physics, Volume 53, Issue 1, January 2026.
Abstract Background Deformable image registration (DIR) is a crucial tool in radiotherapy for analyzing anatomical changes and motion patterns. Current DIR implementations rely on discrete volumetric motion representation, which often leads to compromised accuracy and uncertainty when handling significant anatomical changes and sliding boundaries. This

Contactless Pulse Rate Assessment: Results and Insights for Application in Driving Simulators

Applied Sciences
Remote photoplethysmography (rPPG) offers a promising solution for non-contact driver monitoring by detecting subtle blood flow-induced facial color changes from video. However, motion artifacts in dynamic driving environments remain key challenges. This
