A PCA and Mesh Adaptation‐Based Format for High Compression of Earth Observation Optical Data With Applications in Agriculture

International Journal for Numerical Methods in Engineering, Volume 126, Issue 12, 30 June 2025.
ABSTRACT Earth Observation optical data are critical for agriculture, supporting tasks like vegetation health monitoring, crop classification, and land use analysis. However, the large size of multispectral and hyperspectral datasets poses challenges for storage, transmission, and processing, particularly in precision farming and resource‐limited ...

Mechanical Hamiltonization of Unreduced ϕ$\phi$‐Simple Chaplygin Systems

Studies in Applied Mathematics, Volume 154, Issue 5, May 2025.
ABSTRACT In this paper, we prove that the trajectories of unreduced ϕ$\phi$‐simple Chaplygin kinetic systems are reparameterizations of horizontal geodesics with respect to a modified Riemannian metric. Furthermore, our proof is constructive and these Riemannian metrics, which are not unique, are obtained explicitly in interesting examples.

Recent Advances in Sustainable Total Synthesis and Chiral Pool Strategies with Emphasis on (−)‐Sclareol in Natural Products Synthesis

European Journal of Organic Chemistry, Volume 28, Issue 8, February 24, 2025.
There are continuous efforts to improve total syntheses of natural products, particularly their sustainability, such as developing effective chiral pool approaches relying on a wide spectrum of natural chirons, including (−)‐sclareol as one of the most useful natural chirons.
