Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on the risk of food poisoning due to the presence of biogenic amines in meals made from chicken meat consumed by children under 3 years of age

Food Risk Assess Europe, Volume 4, Issue 2, April 2026.
Abstract Biogenic amines are low molecular weight organic bases that come from the enzymatic decarboxylation of amino acids. They are present in many types of food, with the highest concentrations usually found in fish and their derived products, as well as in beverages and fermented foods of plant, meat and dairy origin.

An hp-adaptive strategy based on continuous Sobolev embeddings [PDF]

, 2011
A new hp-adaptive approach for finite element methods is presented. Specifically, the paper addresses the well-known question of how to effectively decide between h- and p-refinement within an adaptive hp-finite element procedure.

The Brittle Ring Test: A Simple and Reliable Method for Evaluating the Fracture Strength of Technical Ceramics—Theoretical and Experimental Investigations

International Journal of Ceramic Engineering &Science, Volume 8, Issue 2, March 2026.
The study reviews existing formulas for the Brittle Ring test and introduces an adapted equation that most accurately determines the fracture strength of ceramic rings. Valid strength values can be obtained with minimal sample preparation when suitable geometric ratios are maintained, demonstrating the method's efficiency for technical ceramics.

On the convergence of adaptive nonconforming finite element methods for a class of convex variational problems [PDF]

, 2011
We formulate and analyze an adaptive nonconforming finite element method for the solution of convex variational problems. The class of minimization problems we admit includes highly singular problems for which no Euler–Lagrange equation (or inequality ...

A Universal Genomic Approach to Detect Hybridization Using MIPs: Insights From a Case Study on Pike

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Interspecific hybridization poses a major challenge to biodiversity conservation, as genetic introgression can threaten the persistence of native species. This phenomenon occurs when individuals from distinct species interbreed, producing hybrids with a combination of genetic traits from both parents. The implications are especially concerning

Energy norm a-posteriori error estimation for hp-adaptive discontinuous Galerkin methods for elliptic problems in three dimensions [PDF]

We develop the energy norm a-posteriori error estimation for hp-version discontinuous Galerkin (DG) discretizations of elliptic boundary-value problems on 1-irregularly, isotropically refined affine hexahedral meshes in three dimensions.
