A Spectral Matching Algorithm Based on the Wasserstein Metric

Journal of Chemometrics, Volume 40, Issue 6, June 2026.
ABSTRACT Through visual inspection, scientists can easily judge the similarity of pairs of spectra from different sources, whether they are experimental measurements, spectra libraries, or spectra calculations. Spectral similarity is recognized when the peak patterns appear similar, even if the peak positions are shifted or the peak amplitudes are ...

Advanced control of non‐isothermal axial dispersion tubular reactors with recycle‐induced state delay

The Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 3018-3037, June 2026.
Abstract We develop a delay‐aware estimation and control framework for a non‐isothermal axial dispersion tubular reactor modelled as a coupled parabolic‐hyperbolic PDE system with recycle‐induced state delay. The infinite‐dimensional dynamics are preserved without spatial discretization by representing the delay as a transport PDE and adopting a late ...

Restricted Tweedie stochastic block models

Canadian Journal of Statistics, Volume 54, Issue 2, June 2026.
Abstract The stochastic block model (SBM) is a widely used framework for community detection in networks, where the network structure is typically represented by an adjacency matrix. However, conventional SBMs are not directly applicable to an adjacency matrix that consists of nonnegative zero‐inflated continuous edge weights.

Phenome‐ and Genome‐Wide Insights Into Dietary Patterns: Health Consequences and Genetic Basis

eFood, Volume 7, Issue 3, June 2026.
Three new dietary patterns were derived from quadratically regularized‐principal components analysis. These patterns showed strong associations with a wide range of diseases and genetic factors. ABSTRACT Dietary patterns (DPs) integrate complex eating behaviors and provide stronger insights into health than analyses of single nutrients.
