Minisymposium: "Degeneracies and Singularities in PDEs" nell'ambito del congresso: "8th European Conference on Elliptic and Parabolic Problems"

, 2014
It is our intention to present some recent results on linear PDEs involving singular or degenerate operators acting in smooth domains as well as operators with smooth coefficients acting in irregular domains.

Four Decades of Research at the MADE Site and Beyond: Advancing the Understanding and Modeling of Solute Transport in Heterogeneous Media

Reviews of Geophysics, Volume 64, Issue 4, December 2026.
Abstract Spatial heterogeneity, manifested as strong variability in hydraulic conductivity (K) within geological formations, exerts a fundamental control on groundwater flow and solute transport. Because K can vary over multiple orders of magnitude in complex three‐dimensional patterns, predicting contaminant plume migration remains a long‐standing ...

Feedback Linearisation with State Constraints

International Journal of Robust and Nonlinear Control, Volume 36, Issue 17, Page 7579-7595, 25 November 2026.
ABSTRACT Feedback Linearisation (FBL) is a widely used technique that applies feedback laws to transform input‐affine nonlinear control systems into linear control systems, allowing for the use of linear controller design methods such as pole placement.

A New Physics‐Constrained Neural Network Approach to Retrieve CH4 Vertical Profiles From Hyperspectral Infrared Data

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 21, 16 November 2026.
Abstract Methane (CH4 ${\text{CH}}_{4}$) is a critical greenhouse gas, and accurate monitoring of its vertical distribution is essential for understanding its radiative impact and identifying emission sources. This paper introduces a novel methodology using a physics‐constrained neural network based on soft constraints to retrieve CH4 ${\text{CH}}_{4}$

Agentic artificial intelligence in mechanics of materials: A review of building tailored models on demand

GAMM-Mitteilungen, Volume 49, Issue 4, November 2026.
Abstract In mechanics of materials, many powerful methods are accessible only to experts. Constitutive models, for example, describe the relation between stress and strain in materials and are a core ingredient of simulations from structural engineering to biomechanics. Yet building and using such models requires specialized expertise—a barrier for the

Neutrophils: Heterogeneity, Biology, Diseases, and Therapeutic Strategies

MedComm, Volume 7, Issue 11, November 2026.
Neutrophils exhibit remarkable functional plasticity and play dual roles in tissue protection and disease progression. This review summarizes their key biological functions and highlights the shift from conventional broad‐spectrum interventions to neutrophil‐based drug delivery systems.

In Vivo 31P‐MRS of the Human Orthotopic Kidney at 3 Tesla

NMR in Biomedicine, Volume 39, Issue 11, November 2026.
31P‐MRS of healthy human orthotopic kidneys at 3T yielded improved spectral quality within a clinically feasible scan time. The resulting summed spectrum characterizes normal renal phosphorus metabolism and may serve as a reference for detecting metabolic alterations associated with kidney disease and transplantation.

A Level Set Method on Particle Flow Maps

International Journal for Numerical Methods in Engineering, Volume 127, Issue 20, 30 October 2026.
ABSTRACT Accurate interface tracking is central to numerical simulations involving moving boundaries, including multiphase flows, free‐surface dynamics, phase‐change problems, and other interface‐driven processes in computational mechanics. Although, level set methods provide a flexible implicit representation of evolving interfaces, their grid‐based ...

Fracture Modeling of Nearly Incompressible Hyperelastic Materials: A Phase‐Field Approach via Simo–Taylor–Pister Three‐Field Variation

International Journal for Numerical Methods in Engineering, Volume 127, Issue 19, 15 October 2026.
ABSTRACT Incompressibility is commonly observed in the majority of hyperelastic materials, which are fundamental to a wide range of technical applications owing to their distinctive properties, particularly their flexibility, stretchability, and resilience.
