A Riemann problem with small viscosity and dispersion
Electronic Journal of Differential Equations, 2006 In this paper we prove existence of global solutions to a hyperbolic system in elastodynamics, with small viscosity and dispersion terms and derive estimates uniform in the viscosity-dispersion parameters.

Inverse Design for Robust Inference in Integrated Computational Spectrometry
Nanophotonics, Volume 15, Issue 7, 13 April 2026.This work demonstrates that integrated computational spectrometers can be inverse‐designed to substantially improve noise tolerance without relying on training data or specific inference algorithms, offering an alternative to conventional end‐to‐end co‐design strategies.

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.

Contact discontinuities in multi-dimensional isentropic Euler equations
Electronic Journal of Differential Equations, 2018 In this note we partially extend the recent nonuniqueness results on admissible weak solutions to the Riemann problem for the 2D compressible isentropic Euler equations.

Role of Sleep Disturbances and Diabetes‐Related Distress on Glycemic Control: A Path Analysis
Research in Nursing &Health, Volume 49, Issue 2, Page 137-145, April 2026.ABSTRACT Despite advancements in diabetes management technology, many patients with type 2 diabetes (T2D) struggle to achieve optimal glycemic control. Sleep disorders such as obstructive sleep apnea (OSA) and insomnia are common in T2D and linked to poor glycemic control. Insomnia, particularly with short sleep duration, may worsen glycemic control by

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.

, 2013 In this article we investigate the century-old continuous extension problem of the Riemann map. Let $G$ be a simply connected domain. We call $ $ in $\partial G$ a multiple point if there are simply connected subdomains $ U$ and $V$ such that $ \in\partial U \cap\partial V$ and $ dist (\partial U\cap G , \partial V\cap G )>0$.
