Disorder effects at a nematic quantum critical point in d-wave cuprate superconductor

, 2011
A d-wave high temperature cuprate superconductor exhibits a nematic ordering transition at zero temperature. Near the quantum critical point, the coupling between gapless nodal quasiparticles and nematic order parameter fluctuation can result in unusual ...

On the Method of Harmonic Balance for Lumped‐Element Transformer Models

International Journal of Circuit Theory and Applications, Volume 54, Issue 2, Page 625-637, February 2026.
The steady‐state solution of a lumped‐element transformer model with a dry friction‐like hysteresis model depicting the magnetic core is of interest. The harmonic balance method efficiently solves this stiff system. We derive the harmonic balance algorithm, enhance it with performance and convergence improvements, and demonstrate its efficiency by ...

On the inverse nodal problems for discontinuous Sturm–Liouville operators

Journal of Differential Equations, 2016
Recently, a new class of inverse problem so-called inverse nodal problems has attracted the attention of researchers. Inverse nodal problems, in turn, consist in constructing operators from given zeros of their eigenfunctions. In this paper, the authors consider an inverse nodal problem for Sturm Liouville operator with jump condition at the point \(x ...

Frequency‐Domain Subspace Identification for Noninvasive Transformer Winding Parameter Estimation and Fault Diagnostics

International Journal of Circuit Theory and Applications, Volume 54, Issue 2, Page 658-677, February 2026.
Noninvasive frequency‐domain method estimates transformer winding parameters from terminal measurements, eliminating the need for design data. ABSTRACT A novel frequency‐domain subspace identification method enables precise estimation of transformer winding ladder network parameters directly from terminal measurements.

Inverse nodal problem for a p-Laplacian Sturm-Liouville equation with polynomially boundary condition

Electronic Journal of Differential Equations, 2018
In this article, we extend solution of inverse nodal problem for one-dimensional p-Laplacian equation to the case when the boundary condition is polynomially eigenparameter.

Weighted BFBT Preconditioner for Stokes Flow Problems with Highly Heterogeneous Viscosity

, 2017
We present a weighted BFBT approximation (w-BFBT) to the inverse Schur complement of a Stokes system with highly heterogeneous viscosity. When used as part of a Schur complement-based Stokes preconditioner, we observe robust fast convergence for Stokes ...

Neuro‐Immune Crosstalk: Molecular Mechanisms, Biological Functions, Diseases, and Therapeutic Targets

MedComm, Volume 7, Issue 2, February 2026.
Neurons, immune cells, and other cellular components within the disease microenvironment (such as stromal cells and tumor cells) constitute a dynamically evolving ecosystem. Neurons directly modulate immune cell activity and inflammatory responses through the release of neurotransmitters (e.g., norepinephrine and CGRP), while also promoting tumor ...

Trefftz Difference Schemes on Irregular Stencils

, 2009
The recently developed Flexible Local Approximation MEthod (FLAME) produces accurate difference schemes by replacing the usual Taylor expansion with Trefftz functions -- local solutions of the underlying differential equation.
