A Non-Local Structure Tensor Based Approach for Multicomponent Image Recovery Problems

, 2014
Non-Local Total Variation (NLTV) has emerged as a useful tool in variational methods for image recovery problems. In this paper, we extend the NLTV-based regularization to multicomponent images by taking advantage of the Structure Tensor (ST) resulting ...

Entropy Stable Finite Volume Approximations for Ideal Magnetohydrodynamics

, 2017
This article serves as a summary outlining the mathematical entropy analysis of the ideal magnetohydrodynamic (MHD) equations. We select the ideal MHD equations as they are particularly useful for mathematically modeling a wide variety of magnetized ...

Approximation of the Pseudospectral Abscissa via Eigenvalue Perturbation Theory

Numerical Linear Algebra with Applications, Volume 33, Issue 2, April 2026.
ABSTRACT Reliable and efficient computation of the pseudospectral abscissa in the large‐scale setting is still not settled. Unlike the small‐scale setting where there are globally convergent criss‐cross algorithms, all algorithms in the large‐scale setting proposed to date are at best locally convergent.

Monitoring of water volume in a porous reservoir using seismic data: Validation of a numerical model with a field experiment

Near Surface Geophysics, Volume 24, Issue 2, Page 110-127, April 2026.
Abstract As global groundwater levels continue to decline rapidly, there is a growing need for advanced techniques to monitor and manage aquifers effectively. This study focuses on validating a numerical model using seismic data from a small‐scale experimental setup designed to estimate water volume in a porous reservoir.

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Evaluation of preclinical antipsychotic models used to support first‐in‐human clinical trials

British Journal of Pharmacology, Volume 183, Issue 7, Page 1364-1389, April 2026.
Abstract Schizophrenia is regarded as a complex and heterogeneous psychiatric disorder, characterised by diverse symptoms and comorbidities, which complicate both clinical management and drug development. Current pharmacological treatment, primarily based on dopamine D2 receptor antagonism or partial agonism, which has not markedly progressed since the

Palmoplantar pustulosis: pathogenesis, differential diagnosis, and treatment

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, Volume 24, Issue 4, Page 516-535, April 2026.
Summary Palmoplantar pustulosis (PPP) is a chronic inflammatory and often painful disease characterized by sterile pustules on the palms and soles, significantly impairing quality of life. Women are more frequently affected than men, and smoking is a major trigger. Under biologic therapies, especially TNF antagonists, a paradoxical PPP may occur.

Trace Finite Element Methods for PDEs on Surfaces

, 2016
In this paper we consider a class of unfitted finite element methods for discretization of partial differential equations on surfaces. In this class of methods known as the Trace Finite Element Method (TraceFEM), restrictions or traces of background ...
