The refined inviscid stability condition and cellular instability of viscous shock waves [PDF]

open access: yes, 2009
Combining work of Serre and Zumbrun, Benzoni-Gavage, Serre, and Zumbrun, and Texier and Zumbrun, we propose as a mechanism for the onset of cellular instability of viscous shock and detonation waves in a finite-cross-section duct the violation of the ...

Prognostic factors in bushfire‐affected koalas–Kangaroo Island bushfire response 2020

open access: yesAustralian Veterinary Journal, Volume 103, Issue 8, Page 453-463, August 2025.
This study presents a retrospective analysis of clinical records data from koalas presenting for treatment following the large‐scale bushfire event on Kangaroo Island 2019–2020. The aim of the study was to identify prognostic factors for koalas affected by bushfire. Koalas (n = 199) were grouped based on their burn status in combination with their burn

Seismic Signatures of Fluctuating Fragmentation in Volcanic Eruptions

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 1, January 2025.
Abstract Fragmentation plays a critical role in eruption explosivity by influencing the eruptive jet and plume dynamics that may initiate hazards such as pyroclastic flows. The mechanics and progression of fragmentation during an eruption are challenging to constrain observationally, limiting our understanding of this important process.

Diffusion of a nano-wire through an obstacle field

open access: yes, 2016
We report the first experimental realization of a rod diffusing in a two dimensional obstacle field following the single rod dynamics. We use a silver nanowire as our rod and two types of obstacles: repelling light beams and polymer pillars. We study the

The past and future of the study of Islamic esotericism

open access: yesReligion Compass, Volume 18, Issue 7, July 2024.
Abstract The study of Islamic esotericism, particularly the concept of al‐bāṭiniyya, remains fragmented. While often studied under various labels like “mysticism” and “occultism,” it is widely equated to Sufism. Scholars still hesitate to use the term al‐bāṭiniyya due to its historical pejorative connotations, linking it to extremist adherence to ...

On buoyant convection in binary solidification [PDF]

open access: yes, 2005
We consider the problem of nonlinear steady buoyant convection in horizontal mushy layers during the solidification of binary alloys. We investigate both cases of zero vertical volume flux and constant pressure, referred to as impermeable and permeable ...
