Australian continental‐scale heavy mineral patterns track climate, weathering and erosion
Sedimentology, Volume 72, Issue 5, Page 1430-1452, August 2025.ABSTRACT The heavy mineral cargo of sediment is influenced by a complex and variable overprint of climate and environmental processes acting on weathered crystalline basement sources. Here, a continental‐scale heavy mineral compositional dataset of 1315 surface sediment samples, analysed via automated mineralogy, from across Australia is utilized to ...

Uncertainty principles for integral operators
, 2012 The aim of this paper is to prove new uncertainty principles for an integral operator $\tt$ with a bounded kernel for which there is a Plancherel theorem. The first of these results is an extension of Faris's local uncertainty principle which states that

Uncertainty Principles for the Fractional Dunkl Transform
International Journal of Analysis and ApplicationsIn this paper, we examine the Donoho–Stark uncertainty principle in the context of the fractional Dunkl transform. We rigorously derive a formulation of the Donoho–Stark uncertainty principle for the fractional Dunkl transform and provide an application ...

A Fractional Laplacian and Its Extension Problem
Mathematical Methods in the Applied Sciences, Volume 48, Issue 9, Page 9840-9852, June 2025.ABSTRACT In this paper, we establish four equivalent characterizations of the fractional Laplacian operator (−‖x‖Δk)σ$$ {\left(-\left\Vert x\right\Vert {\Delta}_k\right)}^{\sigma } $$ with 0<σ<1$$ 0<\sigma <1 $$, in some class of functions on ℝd$$ {\mathbb{R}}^d $$.

Corrosion of zirconium‐based refractories in glass‐contact areas: Mechanisms and challenges
International Journal of Applied Ceramic Technology, Volume 22, Issue 3, May/June 2025.Abstract Zirconium‐based refractories are essential materials in the glass industry due to their outstanding properties including high refractoriness, good thermal shock resistance, and high corrosion resistance with respect to contact with the molten glass, making them suitable for use in critical parts of glass melting furnaces, such as the bottom ...

Journal of Metamorphic Geology, Volume 43, Issue 3, Page 257-285, April 2025.ABSTRACT Exhumed high‐P/low‐T complexes are of paramount importance to directly access rocks that experienced subduction zone processes. However, the original tectono‐metamorphic fabrics are often partially obliterated by exhumation and later deformation, hindering our understanding of the processes occurring at depth.

Dunkl operators and a family of realizations of sop(1|2) [PDF]
, 2012 In this paper, a family of radial deformations of the realization of the Lie superalgebra osp(1 vertical bar 2) in the theory of Dunkl operators is obtained. This leads to a Dirac operator depending on 3 parameters.
