Common‐Mode Rejection Shifted‐Excitation Raman Difference Spectroscopy (CMR‐SERDS) Preserves Broad Structure Predictive of Soil Organic Carbon

open access: yesJournal of Raman Spectroscopy, EarlyView.
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

High‐Fidelity Synthetic Raman Spectra Generation for Sinter Basicity Prediction Using β$$ \beta $$‐Variational Autoencoders

open access: yesJournal of Raman Spectroscopy, EarlyView.
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.

Mycotoxin management in the cereal supply chain: Advanced detection, detoxification, and smart packaging strategies

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
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

Annual–Perennial Forage Mixtures Improve Forage Productivity and Soil Quality in Patchily Degraded Cultivated Pastures Under Grazing Management

open access: yesLand Degradation &Development, EarlyView.
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 ...

Harnessing Optical Limiting in Saturable Absorbers for Reconfigurable Spectral Engineering of Ultrafast Fiber Lasers

open access: yesLaser &Photonics Reviews, EarlyView.
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

open access: yesMacromolecular Symposia, EarlyView.
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
