Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

Advanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

Regularity of Multivariate Refinable Functions

Constructive Approximation, 1999
The regularity of univariate compactly supported refinable functions is known to be related to the spectral properties of an associated transfer operator. The authors derive similar results for the case of multivariate refinable functions with a general dilation matrix \(A\).

Multivariate symmetric refinable functions and function vectors

International Journal of Wavelets, Multiresolution and Information Processing, 2016
For any symmetry group [Formula: see text], any appropriate matrix dilation (compatible with [Formula: see text]) and any appropriate symmetry center [Formula: see text] we give an explicit method for the construction of [Formula: see text]-symmetric with respect to the center [Formula: see text] refinable masks which have sum rule of an arbitrary ...

Refinements of Jessen’s Functional

Ukrainian Mathematical Journal, 2016
In this paper we obtain new refinements of Jessen's functional, defined by means of positive linear functionals. Derived results are then applied to weighted generalized and power means. We also obtain new refinements of numerous classical inequalities such as arithmetic-geometric mean inequality, Young's inequality and Holder's inequality.

Material-adapted refinable basis functions for elasticity simulation

ACM Transactions on Graphics, 2019
In this paper, we introduce a hierarchical construction of material-adapted refinable basis functions and associated wavelets to offer efficient coarse-graining of linear elastic objects.

Refinable Functions: Positivity and Interpolation

Analysis and Applications, 2003
This paper examines two properties of refinable functions. The first provides conditions under which a refinable function is strictly positive and the other presents a conjecture about cardinal interpolation by refinable functions. The conjecture is supported by some analysis and also computation.
