Inequities in neurological care: Access to services, care gaps, and other barriers—A systematic review [PDF]

open access: yesEuropean Journal of Neurology, Volume 32, Issue 1, January 2025.
Abstract Background and purpose Health disparities and inequities are an important and too long overlooked public health concern worldwide. These differences in health and health care can affect people with any disease, including neurological disorders.

Semi-infinite orbits in affine flag varieties and homology of affine Springer fibers [PDF]

open access: yesForum of Mathematics, Sigma 13 (2025) e43, 2021
Let $G$ be a connected reductive group over an algebraically closed field $k$, and let $Fl$ be the affine flag variety of $G$. For every regular semisimple element $\gamma$ of $G(k((t)))$, the affine Springer fiber $Fl_{\gamma}$ can be presented as a union of closed subvarieties $Fl^{\leq w}_{\gamma}$, defined as the intersection of $Fl_{\gamma}$ with ...

Stability of isometric immersions of hypersurfaces [PDF]

open access: yesForum of Mathematics, Sigma. 2024;12:e43, 2023
We prove a stability result of isometric immersions of hypersurfaces in Riemannian manifolds, with respect to $L^p$-perturbations of their fundamental forms: For a manifold $M^d$ endowed with a reference metric and a reference shape operator, we show that a sequence of immersions $f_n:M^d\to N^{d+1}$, whose pullback metrics and shape operators are ...

Semisimplification for Subgroups of Reductive Algebraic Groups [PDF]

open access: yesForum of Mathematics, Sigma 8 (2020) e43, 2020
Let $G$ be a reductive algebraic group---possibly non-connected---over a field $k$ and let $H$ be a subgroup of $G$. If $G= GL_n$ then there is a degeneration process for obtaining from $H$ a completely reducible subgroup $H'$ of $G$; one takes a limit of $H$ along a cocharacter of $G$ in an appropriate sense.

The Moduli Space of Harnack Curves in Toric Surfaces [PDF]

open access: yesForum of Mathematics, Sigma 9 (2021) e43, 2017
In 2006, Kenyon and Okounkov computed the moduli space of Harnack curves of degree $d$ in $\mathbb{C}\mathbb{P}^2$. We generalize to any projective toric surface some of the techniques used there. More precisely, we show that the moduli space $\mathcal{H}_\Delta$ of Harnack curves with Newton polygon $\Delta$ is diffeomorphic to $\mathbb{R}^{m-3}\times\

Measuring Shocks to Central Bank Independence using Legal Rulings [PDF]

open access: yesarXiv, 2022
We investigate the consequences of legal rulings on the conduct of monetary policy. Several unconventional monetary policy measures of the European Central Bank have come under scrutiny before national courts and the European Court of Justice. These lawsuits have the potential to severely impact the scope and flexibility of central bank policies, and ...

General Bayesian time-varying parameter VARs for predicting government bond yields [PDF]

open access: yesarXiv, 2021
Time-varying parameter (TVP) regressions commonly assume that time-variation in the coefficients is determined by a simple stochastic process such as a random walk. While such models are capable of capturing a wide range of dynamic patterns, the true nature of time variation might stem from other sources, or arise from different laws of motion. In this

Joint Wire Cutting with Non‐Maximally Entangled States

open access: yesAdvanced Quantum Technologies, EarlyView.
Wire cutting decomposes large quantum circuits into smaller subcircuits by severing connecting wires, enabling execution on multiple distributed devices. This study employs non‐maximally entangled (NME) states in joint wire cuts to reduce their overhead.

The expressway network design problem for multiple urban subregions based on the macroscopic fundamental diagram

open access: yesComputer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract With the advancement of urbanization, cities are constructing expressways to meet complex travel demands. However, traditional link‐based road network design methods face challenges in addressing large‐scale expressway network design problems.
