Circularly Polarized Luminescence in Rotaxanes and Catenanes

ChemistryEurope, EarlyView.
This review highlights the chiral rotaxanes and catenanes possessing static or stimuli‐responsive circularly polarized luminescence (CPL) activity both in solution and in the solid state. It also discusses macromolecular and supramolecular CPL‐emissive materials derived from these mechanically interlocked molecules.

Probabilistic weighted Dirichlet process mixture with an application to stochastic volatility models

Canadian Journal of Statistics, EarlyView.
Abstract In this article, we propose a flexible Bayesian modelling framework and investigate the probabilistic weighted Dirichlet process mixture (pWDPM). The construction and properties of a probabilistic weight function are illustrated. The advantage of the pWDPM under the log‐squared transformed stochastic volatility (SV) model is demonstrated.

Multi‐Response Optimization of the Thermal and Thermomechanical Behavior of a Steel Ladle Lining using Grey Relational Analysis and Technique for Order Preference by Similarity to Ideal Solution

steel research international, Volume 94, Issue 1, January 2023., 2023
This study offers a methodology to simultaneously optimize the thermal and thermomechanical behavior of a steel ladle lining using grey relational analysis (GRA) and technique for order preference by similarity to ideal solution (TOPSIS). With the proposed methodology, the best solution, the optimal levels, and quantitative contribution of lining ...

The infinity(x)-Laplace equation in Riemannian vector fields

Electronic Journal of Differential Equations, 2015
We employ Riemannian jets which are adapted to the Riemannian geometry to obtain the existence-uniqueness of viscosity solutions to the infinity(x)-Laplace equation in Riemannian vector fields.

A parameter transformation of the anisotropic Matérn covariance function

Canadian Journal of Statistics, EarlyView.
Abstract We describe a polar coordinate transformation of the anisotropy parameters of the Matérn covariance function, which provides two benefits over the standard parameterization. First, it identifies a single point (the origin) with the special case of isotropy.

First‐order Sobolev spaces, self‐similar energies and energy measures on the Sierpiński carpet

Communications on Pure and Applied Mathematics, EarlyView.
Abstract For any p∈(1,∞)$p \in (1,\infty)$, we construct p$p$‐energies and the corresponding p$p$‐energy measures on the Sierpiński carpet. A salient feature of our Sobolev space is the self‐similarity of energy. An important motivation for the construction of self‐similar energy and energy measures is to determine whether or not the Ahlfors regular ...
