Mathematical Modeling of Measured Recalescence Velocities

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT A moving‐boundary problem of synchronous directional and volumetric solidification in undercooled liquid drops is formulated and solved. Directional solidification is caused by the temperature gradient along the spatial direction, whereas volumetric growth of new phase elements is caused by the melt undercooling ahead of the phase transition ...

Subject grounding to reduce electromagnetic interference for MRI scanners operating in unshielded environments

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose Portable low‐field (<0.1T) MRI is increasingly used for point‐of‐care imaging, but electromagnetic interference (EMI) presents a significant challenge, especially in unshielded environments. EMI can degrade image quality and compromise diagnostic utility.

Landscape heterogeneity shapes the spatial and diet partitioning of a montane carnivore guild

Oikos, EarlyView.
Interspecific competition is a structural force in animal communities and can be particularly influential among species with similar taxonomic or ecological characteristics. In carnivore communities, heterogeneity in resource availability and landscape structure can ameliorate competitive interactions, but it is often difficult to quantify the space ...
