Role of Anharmonicity and Bimetallic Intermixing in the IR and Raman Spectra of Cun$_{n}$ and Pdn$_{n}$Cu6−n$_{6-n}$ Clusters (n<7$n\lt 7$). Ab Initio Benchmarking of DFT

Small Structures, Volume 7, Issue 5, May 2026.
High‐level ab initio and density functional theory calculations reveal a structural and spectroscopic transition from pla nar Cu6 to three‐dimensional Pd6, whose lowest energy triplet state undergoes a Jahn‐Teller distortion. This evolution from molecule‐like to metal‐like bonding produces distinct infrared and Raman fingerprints, providing reliable ...

A Method to Estimate Health Effects Based on Error‐Prone Simulated Environmental Exposure: An Application to a Multi‐Country Study on Birthweight and Fine Particulate Matter

GeoHealth, Volume 10, Issue 5, May 2026.
Abstract Earth System Models provide spatiotemporally continuous environmental exposure data but remain underused in environmental epidemiology because of uncertainty from measurement errors. We developed a novel latent‐variable approach to correct for measurement error characterized by spatiotemporal error covariance, which was derived from ...

The SPoRC Stock Assessment Package: A Generalized Next‐Generation Platform to Assess Spatial, Age and Sex‐Structured Populations

Fish and Fisheries, Volume 27, Issue 3, Page 754-770, May 2026.
ABSTRACT Fisheries managers increasingly rely on stock assessment models to provide sustainable management advice, which must balance complex and competing objectives. Although assessment models necessitate simplifying assumptions, there is increasing recognition to improve the integration of realistic biological and fishery dynamics. While ongoing and

Curvature of Hessian manifolds

Curvature of Hessian manifolds
We prove that, in dimensions greater than 2, the generic metric is not a Hessian metric and find a curvature condition on Hessian metrics in dimensions greater than 3. In particular we prove that the forms used to define the Pontryagin classes in terms of the curvature vanish on a Hessian manifold.
