Real‐time fault detection in multicomponent nuclear‐waste slurries through data fusion of spectroscopic sensors

AIChE Journal, Volume 72, Issue 5, May 2026.
Abstract Three instruments–Raman spectroscopy, attenuated total reflectance–Fourier transform infrared spectroscopy, and focused beam reflectance measurement–were used to detect sensor faults, mixing faults, and unanticipated chemistry in a system of multicomponent slurries.

Clinically Deployable Handwriting Biomarkers of Parkinson's Disease via Multiscale Attention and Bayesian–Genetic Optimization

Brain and Behavior, Volume 16, Issue 5, May 2026.
Tablet‐based handwriting tasks (spiral, meander, and wave) are transformed into unified images and analyzed using PD‐MGMA‐DSCNN, a lightweight multiscale gated attention network. Bayesian–genetic optimization improves performance, while SHAP attribution maps provide interpretable handwriting biomarkers for Parkinson's disease screening.

How to Visualize Computational Mechanics: Animating Finite Elements, Continuum Mechanics, and Tensor Calculus

Computer Applications in Engineering Education, Volume 34, Issue 3, May 2026.
ABSTRACT Computational mechanics is inherently complex, as the underlying physical processes evolve in three spatial dimensions and time. Thus, intuitive visualizations in traditional lecture notes or on blackboards are challenging. This motivates the use of animation software to illustrate time‐dependent three‐dimensional phenomena, which complement ...

Bayesian Poisson‐Lognormal Regression With Compositional Effect Shares for Multivariate Count Data

Environmetrics, Volume 37, Issue 4, -Not available-.
ABSTRACT Multivariate count data are central in community ecology and related fields, where interest lies in how environmental gradients and management actions jointly shape the abundances of many taxa. The Poisson‐lognormal (PLN) model is a natural workhorse in this setting, accommodating overdispersion and cross‐taxon dependence via a latent Gaussian

Microencapsulated Alkane Wax Melting: Measured by 1H NMR Relaxometry and Diffusometry

Magnetic Resonance in Chemistry, Volume 64, Issue 5, Page 483-493, May 2026.
NMR relaxometry and diffusometry measurements detected greater molecular‐level disordering in microencapsulated n‐alkane waxes versus unencapsulated waxes throughout melting. ABSTRACT Phase change materials (PCMs) are useful for energy storage. Large latent heats make n‐alkane waxes effective PCMs.
