Adaptive Optical Layers: Efficient Tall Cell Grids for Liquid Simulation
Computer Graphics Forum, EarlyView.Abstract Tall cell grids have been proposed as an efficient approach to accelerate large‐scale liquid simulation. In this framework, regions near the liquid surface are discretized with regular grids, while regions farther away are represented by elongated rectangular cells.

Parameters that remain consistent independent of pausing before gait-initiation during normal rise-to-walk behaviour delineated by sit-to-walk and sit-to-stand-and-walk. [PDF]
PLoS ONE, 2018 BACKGROUND:Rising-to-walk is an everyday transitional movement task rarely employed in gait rehabilitation. Sit-to-walk (STW) and sit-to-stand-and-walk (STSW), where a pause separates sit-to-stand and gait-initiation (GI) represent extremes of rising-to ...

Cross Carbonyl‐Olefin Metathesis of Unactivated Olefins
Advanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.A method for the olefination of aryl aldehydes with unactivated alkenes via cross carbonyl‐olefin metathesis is described. Reaction of an aldehyde substrate with a cis−1,2‐disubstituted or monosubstituted olefin using the HBF4 salt of 2,3‐diazabicyclo[2.2.2]octane results in high‐yielding olefination with exclusive trans stereoselectivity. The reaction

Macro Monte Carlo dose calculation for very high energy electron (VHEE) radiotherapy
Medical Physics, Volume 53, Issue 7, July 2026.Abstract Background Very high energy electron (VHEE) radiotherapy has gained growing interest owing to its potential to reach deep‐seated targets and induce FLASH effect. Dose calculations can be performed using analytical or Monte Carlo (MC) methods. Analytical approaches enable rapid dose computation but suffer from limited accuracy in heterogeneous ...

Integrated X‐Ray, Gamma Radiation, and Micro‐CT Techniques for Quantitative Wood Characterization
X-Ray Spectrometry, Volume 55, Issue 4, Page 612-628, July/August 2026.ABSTRACT The present research integrates microcomputed tomography (micro‐CT), x‐ray fluorescence, and gamma‐ray transmission to quantitatively characterize wood species. A total of 22 samples from seven species were analyzed for density (ρ), linear attenuation coefficient (μ), Compton scattering, micro‐CT gray values (GV), porosity, mass attenuation ...
