A stabilized radial basis-finite difference (RBF-FD) method with hybrid kernels

, 2018
Recent developments have made it possible to overcome grid-based limitations of finite difference (FD) methods by adopting the kernel-based meshless framework using radial basis functions (RBFs). Such an approach provides a meshless implementation and is

No‐regret and low‐regret control for a weakly coupled abstract hyperbolic system

Asian Journal of Control, EarlyView.
Abstract This paper explores an optimal control problem of weakly coupled abstract hyperbolic systems with missing initial data. Hyperbolic systems, known for their wave‐like phenomena and complexity, become even more challenging with weak coupling between subsystems.

Mathematical Analysis of the PDE Model for the Consensus-based Optimization

In this paper, we develop an analytical framework for the partial differential equation underlying the consensus-based optimization model. The main challenge arises from the nonlinear, nonlocal nature of the consensus point, coupled with a diffusion term that is both singular and degenerate. By employing a regularization procedure in combination with a

Quasi‐invariance of Gaussian measures for the 3d$3d$ energy critical nonlinear Schrödinger equation

Communications on Pure and Applied Mathematics, EarlyView.
Abstract We consider the 3d$3d$ energy critical nonlinear Schrödinger equation with data distributed according to the Gaussian measure with covariance operator (1−Δ)−s$(1-\Delta)^{-s}$, where Δ$\Delta$ is the Laplace operator and s$s$ is sufficiently large. We prove that the flow sends full measure sets to full measure sets. We also discuss some simple

Quantization, PDEs, and Geometry

, 2016
This book presents four survey articles on different topics in mathematical analysis that are closely linked to concepts and applications in physics. Specifically, it discusses global aspects of elliptic PDEs, Berezin-Toeplitz quantization, the stability of solitary waves, and sub-Riemannian geometry.

Severity of effect considerations regarding the use of mutation as a toxicological endpoint for risk assessment: A report from the 8th International Workshop on Genotoxicity Testing (IWGT)

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Exposure levels without appreciable human health risk may be determined by dividing a point of departure on a dose–response curve (e.g., benchmark dose) by a composite adjustment factor (AF). An “effect severity” AF (ESAF) is employed in some regulatory contexts.

Performance Analysis of Pulse Detonation Micro Gas Turbines Under Typical Operating Conditions

Energy Science &Engineering, EarlyView.
ABSTRACT Considering the benefits of pulse detonation combustion, including low entropy increase, high cycle thermal efficiency, and self‐pressurization, a performance calculation model for a pulse detonation micro gas turbine was established using methane as fuel. The study primarily investigated the impact of component parameters, ambient conditions,

Optimization of Thermally Radiative and Mass Wavy Flow Analysis Affected by Induced Magnetic Field and Joule Heating

Energy Science &Engineering, EarlyView.
ABSTRACT The role of magnetic induction is declared fundamental in many technological systems, including electric generators, inductors, transformers, and so on. This is an important source for converting energy from one form to another while utilizing electromagnetic induction. This phenomenon is efficient when the induced magnetic field is introduced
