Weighted cscK metrics (I): A priori estimates

Journal of Functional Analysis
There was a mistake in Lemma 5.5 and Lemma 5.6 where an important term in the estimates was wrongly neglected. We corrected them.

Towards a robust a priori choice of Padé approximants for fast frequency sweeps of finite element problems [PDF]

, 2015
In this work, a solution strategy based on the use of Padé approximants is investigated for efficient solution of parametric finite element problems such as, for example, frequency sweep analyses.

On a priori energy estimates for characteristic boundary value problems [PDF]

, 2014
Motivated by the study of certain non linear free-boundary value problems for hyperbolic systems of partial differential equations arising in Magneto-Hydrodynamics, in this paper we show that an a priori estimate of the solution to certain boundary value

Investigation of Complement Activation and Cytokine Signatures in AQP4+ NMOSD, MOGAD, and MS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Aquaporin‐4‐IgG seropositive neuromyelitis optica spectrum disorder (AQP4+ NMOSD), myelin oligodendrocyte glycoprotein antibody‐associated disease (MOGAD), and multiple sclerosis (MS) are pathophysiologically distinct neuroinflammatory disorders. Complement activation is a major mechanism of injury in AQP4+ NMOSD, whereas its role in

A PRIORI ESTIMATE ON THE FREE BOUNDARY PROBLEM AND ITS APPLICATION [PDF]

application/pdfThe free boundary problem with the area functional is investigated. A priori estimate for the measure of the caved part of the set where the function is zero is obtained, so that a convex property of the free boundary is ...

Holder continuity of bounded weak solutions to generalized parabolic p-Laplacian equations II: singular case

Electronic Journal of Differential Equations, 2015
Here we generalize quasilinear parabolic p-Laplacian type equations to obtain the prototype equation $$ u_t - \hbox{div} \Big(\frac{g(|Du|)}{|Du|} Du\Big) = 0, $$ where g is a nonnegative, increasing, and continuous function trapped in between two ...

A priori estimate for the Nirenberg problem

Discrete and Continuous Dynamical Systems - S, 2008
We establish a priori estimate for solutions to the prescribing Gaussian curvature equation $ - \Delta u + 1 = K(x) e^{2u}, x \in S^2,$  (1) for functions $K(x)$ which are allowed to change signs. In [16], Chang, Gursky and Yang obtained a priori estimate for the solution of (1) under the condition that the function K(x) be positive

A Two‐Stage Plasma Biomarker Algorithm Reduces Amyloid PET Use and the p‐Tau217 Gray Zone

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Plasma p‐Tau217 leaves 30%–50% of patients in an indeterminate “gray zone” often requiring Aβ‐PET. We developed GRAD (Gatekeeper‐Reflex for Alzheimer's Disease), a two‐stage Aβ‐positivity prediction model to improve classification while reserving Aβ‐PET for residual uncertainty.

Positive solutions for a 2nth-order p-Laplacian boundary value problem involving all derivatives

Electronic Journal of Differential Equations, 2013
In this work, we are mainly concerned with the positive solutions for the 2nth-order p-Laplacian boundary-value problem $$displaylines{ -(((-1)^{n-1}x^{(2n-1)})^{p-1})' =f(t,x,x',ldots,(-1)^{n-1}x^{(2n-2)},(-1)^{n-1}x^{(2n-1)}),cr x^{(2i)}(0)=x ...

A Priori Error Estimate of a Multiscale Finite Element Method for Transport Modeling [PDF]

, 2015
International audienceThis work proposes an \textit{a priori} error estimate of a multiscale finite element method to solve convection-diffusion problems where both velocity and diffusion coefficient exhibit strong variations at a scale which is much ...
