Regularization via f‐Divergence: An Application to Multi‐Oxide Spectroscopic Analysis

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract In this paper, we explore the application of convolutional neural networks (CNNs) for predicting the chemical composition of complex geologic samples in a simulated Martian atmospheric environment. Specifically, we aim to characterize oxide weight percentages (wt.%) of rock samples analyzed by remote Laser‐Induced Breakdown Spectroscopy (LIBS),

Untangling nutrient co‐regulation of ombrotrophic peatland development

Boreas, Volume 55, Issue 2, Page 384-404, April 2026.
Multi‐method (FTIR, FT‐NIR and TGA) approaches characterizing the organic peat constituents at Holcroft Moss reveal a record of switches that reflect broadly hydroclimate variability governing the decomposition patterns. There are periods, however, where hydroclimate does not fully explain the variability observed and instead changes appear linked to ...

Peri‐Implant Crevicular Fluid Analysis by Mid‐Infrared Spectroscopy in Peri‐Implantitis—A Pilot Study

Clinical Oral Implants Research, Volume 37, Issue 4, Page 453-467, April 2026.
ABSTRACT Objectives This study aimed to assess biochemical differences in peri‐implant crevicular fluid (PICF) using ATR‐FTIR spectroscopy and multivariate analysis, through a between‐participant comparison of healthy and peri‐implantitis (PI) sites, and a within‐participant comparison of PI‐PICF and GCF from contralateral periodontal healthy teeth ...
