On the Stability Barrier of Hermite Type Discretizations of Advection Equations
ABSTRACT We establish a stability barrier for a class of high‐order Hermite‐type discretization of 1D advection equations underlying the hybrid‐variable (HV) and active flux (AF) methods. These methods approximate both cell averages and nodal solutions and evolve them in time simultaneously.

ABSTRACT Harmonizable processes are a class of nonstationary time series, that are characterized by their dependence between different frequencies of a time series. The covariance between two frequencies is the dual frequency spectral density, an object analogous to the spectral density function.

On certain extremal Banach–Mazur distances and Ader's characterization of distance ellipsoids
Abstract A classical consequence of the John Ellipsoid Theorem is the upper bound n$\sqrt {n}$ on the Banach–Mazur distance between the Euclidean ball and any symmetric convex body in Rn$\mathbb {R}^n$. Equality is attained for the parallelotope and the cross‐polytope. While it is known that they are unique with this property for n=2$n=2$ but not for n⩾

Data Driven Control of Defect Formation in Solution Deposited Sb2Se3 Thin Films
A data‐driven design of experiments (DoE) approach is used to uncover how six interdependent processing parameters govern defect formation in solution‐deposited Sb2Se3 thin films. Statistical modeling revealed strong non‐linear couplings that control film quality, and the optimized films showed a threefold enhancement in photoresponse, demonstrating ...

Relative weathering indices and three‐dimensional fabric analyses demonstrate allochthonous emplacement of the Hickory Run Boulder Field via periglacial mass movement. Spatially coherent trends confirm a time‐transgressive surface formed under Pleistocene permafrost conditions, with tributary‐like integration of clasts from a secondary boulder field ...

On the Behavior of Two C1 Finite Elements Versus Anisotropic Diffusion
Bi‐cubic Hemite‐Bézier and reduced cubic Hsieh‐Clough‐Tocher finite elements, of class C1, are compared for the solution of a highly anisotropic diffusion equation. They are tested numerically for various ratios of the diffusion coefficients on different meshes, even aligned with the anisotropy.
