The structural response of network former mixing in barium borosilicate glasses: Part 1
Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.This is a joint experimental and theoretical investigation of the structural response of the mixed network‐former effect along the barium diborate–disilicate join. Theory and spectroscopy, including NMR, Raman, and FTIR, reveal that the highest network connectivity corresponds to the highest atomic packing density. Abstract A glass series with constant

Abstract and Applied Analysis, 2006 The system of quasilinear equations for symmetric flows of a viscous heat-conducting gas with a free external boundary is considered. For global in time weak solutions having nonstrictly positive density, the linear in time two-sided bounds for the gas ...

Blow-Up and Global Existence for a Quasilinear Parabolic System
Discrete Dynamics in Nature and Society, 2014 The problem of solutions to a class of quasilinear coupling parabolic system was studied. By constructing weak upper-solutions and weak lower-solutions, we obtain the global existence and blow-up of solutions under appropriate conditions.

Chaos and unpredictability with time inconsistent policy makers
Theoretical Economics, Volume 21, Issue 1, Page 241-280, January 2026.We analyze the existence of equilibria with complex dynamics in a policy framework with time inconsistency. We consider an economy where, in each period, the policy maker in power determines the level of a durable public good (or bad) that creates strategic linkages across policy periods. When the decision‐making process is time consistent—such as when

Advances in Organic In‐Sensor Neuromorphic Computing: from Material Mechanisms to Applications
Advanced Intelligent Discovery, Volume 1, Issue 3, December 2025.This review discusses organic in‐sensor neuromorphic computing for wearable and bioelectronic systems, with a focus on memory‐based and OECT‐based synaptic devices. It highlights key design principles, recent advances, and existing challenges. By integrating sensing and processing within organic materials, the approach enables real‐time, low‐power, and

Fractional nonlocal impulsive quasilinear multi-delay integro-differential systems
Advances in Difference Equations, 2011 In this article, sufficient conditions for the existence result of quasilinear multi-delay integro-differential equations of fractional orders with nonlocal impulsive conditions in Banach spaces have been presented using fractional calculus, resolvent ...

Engineering Reports, Volume 7, Issue 12, December 2025.Bio‐inspired PLA‐hemp sandwich cores with honeycomb and lotus root geometries were 3D printed and tested. Lotus designs showed superior damping and stable dynamic response, while honeycomb cores offered higher stiffness. Simulations matched experiments closely. ABSTRACT This study investigates the elastic behavior and dynamic mechanical response of bio‐

A subsolution-supersolution method for quasilinear systems
Electronic Journal of Differential Equations, 2005 Assuming that a system of quasilinear equations of gradient type admits a strict supersolution and a strict subsolution, we show that it also admits a positive solution.
