Wave Propagation in Non‐Uniform Media by Linear Expansion of the Refraction Law
PAMM, Volume 26, Issue 1, March 2026.ABSTRACT The propagation of mechanical waves in an unbounded, non‐uniform medium can be described by using curvilinear coordinates centered at the source position. The Frenet coordinate system, with origin on a point riding a wave, is used as a basis for the curvilinear coordinates.

Denoising Multi‐Color QR Codes and Stiefel‐Valued Data by Relaxed Regularizations
PAMM, Volume 26, Issue 1, March 2026.ABSTRACT The handling of manifold‐valued data, for instance, plays a central role in color restoration tasks relying on circle‐ or sphere‐valued color models, in the study of rotational or directional information related to the special orthogonal group, and in Gaussian image processing, where the pixel statistics are interpreted as values on the ...

Glacier‐Atmosphere Interactions and Feedbacks in High‐Mountain Regions ‐ A Review
Reviews of Geophysics, Volume 64, Issue 1, March 2026.Abstract Mountain glaciers are among the natural systems most vulnerable to climate change. However, their interactions with the atmosphere are complex and not fully understood. These interactions can trigger rapid adjustments and climate feedbacks that either amplify or attenuate atmospheric signals, influencing both glacier response and large‐scale ...

Mathematical Methods in the Applied Sciences, Volume 49, Issue 3, Page 1914-1942, February 2026.ABSTRACT Examining the extent to which measurements of rotation matrices are close to each other is challenging due measurement noise. To overcome this, data is typically smoothed, and the Riemannian and Euclidean metrics are applied. However, if rotation matrices are not directly measured and are instead formed by eigenvectors of measured symmetric ...

Concentration in cross‐border research collaborations and MNCs' knowledge creation in a host country
Strategic Management Journal, Volume 47, Issue 2, Page 555-582, February 2026.Abstract Research Summary This study elucidates the previously underexplored structural heterogeneity inherent in multinational corporations' (MNCs) internal linkages by examining the concentration of cross‐border collaborations among inventors within host countries.

Biological Reviews, Volume 101, Issue 1, Page 128-146, February 2026.ABSTRACT The browning of freshwater ecosystems is increasingly evident in temperate and northern regions, with widespread ramifications for lake physics, chemistry, and biology. Contrasting results on how freshwater browning may impact fish have been reported, but there has been no comprehensive examination of how browning may cause cascading effects ...
