Common‐mode rejection (CMR) is introduced as a physics‐motivated preprocessing method for shifted excitation Raman difference spectroscopy (SERDS) that removes the shared background of paired measurements while preserving the noncommon excitation‐dependent component. Applied to more than 900 North American soil samples, CMR improves soil organic carbon

A β$$ \beta $$‐variational autoencoder with β$$ \beta $$ = 0.1 generates high‐fidelity synthetic Raman spectra of industrial sinter with a 16‐fold improvement in spectral fidelity over SMOTE‐based augmentation (KL divergence: 0.0075 vs. 0.121), enabling reliable basicity prediction (R2 = 0.83) from limited labeled datasets.

Abstract Mycotoxins remain a persistent threat to the safety and quality of cereal grains and other agricultural products, and their impact on human health continues to raise global concerns. In many situations, the practices traditionally used to control these toxins are no longer sufficiently effective. They can be costly, difficult to implement on a

ABSTRACT Patchy degradation of cultivated pastures under long‐term grazing is a serious issue limiting grassland productivity. The use of annual and perennial legume–grass mixtures, which offer complementary functional advantages, may provide a practical reseeding‐based approach for improving patchily degraded cultivated pastures; however, limited ...

Optical limiting in a nanomaterial‐polymer saturable absorber is harnessed as a functional intracavity degree of freedom, where pump‐controlled photothermal loss continuously reshapes the gain spectrum of rare‐earth ions, enabling non‐mechanical spectral engineering in an ultrafast fiber laser.

Methodologies for Dataset Analysis in Regard to Obtaining Material Characteristics Using Lamb Waves
ABSTRACT Nondestructive testing has been a fundamental technique in material characterization for an extended period, offering the distinct advantage of preserving the integrity of the tested specimen. Among the conventional methodologies, the pulse‐echo technique has been widely employed for the determination of the Young's modulus and Poisson's ratio
