Colouring and Covering Nowhere Dense Graphs

open access: yes, 2018
It was shown by Grohe et al. that nowhere dense classes of graphs admit sparse neighbourhood covers of small degree. We show that a monotone graph class admits sparse neighbourhood covers if and only if it is nowhere dense.

Max Dvořák and Austrian Denkmalpflege at War [PDF]

open access: yesJournal of Art Historiography, 2009
As was often the case with Vienna School art historians, Max Dvořák (1874-1921) contributed a significant amount to the theory and practice of monument preservation.

Spatially resolved measurement of hydroxyl (OH) radical concentration in a microwave plasma jet by planar laser-induced fluorescence [PDF]

open access: yes, 2014
The spatially resolved concentration of OH radicals in the effluent of a microwave (MW) surfatron plasma jet was measured by planar laser-induced fluorescence. Two cases were compared – constant MW power and MW power modulated by 80 Hz. In both cases the

Improper colourings inspired by Hadwiger’s conjecture [PDF]

open access: yes, 2018
Hadwiger’s Conjecture asserts that every Kt-minor-free graph has a proper (t − 1)-colouring. We relax the conclusion in Hadwiger’s Conjecture via improper colourings.

Linking Superoxide Production and Scavenging in Plant Development

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Due to their strong oxidizing potential, rapid membrane permeability, and high reactivity, reactive oxygen species (ROS) play essential roles in plant development and stress responses. Superoxide (O2•‐) is a primary product of molecular oxygen reduction and a crucial source of hydrogen peroxide, representing a ROS species of substantial ...

The Generalised Colouring Numbers on Classes of Bounded Expansion [PDF]

open access: yes, 2016
The generalised colouring numbers $\mathrm{adm}_r(G)$, $\mathrm{col}_r(G)$, and $\mathrm{wcol}_r(G)$ were introduced by Kierstead and Yang as generalisations of the usual colouring number, also known as the degeneracy of a graph, and have since then ...

Seismic Stratigraphy of Eocene–Recent Mixed Depositional Systems on the SE New Zealand Continental Margin, Great South Basin

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The continental margin of SE New Zealand is strongly influenced by the Southland Current and associated water masses. This new seismic stratigraphic study of the margin has revealed a range of depositional mounds and erosional channels that document the close interaction of turbidity and bottom currents in shaping the margin from the Mid‐Eocene onward.

Detection of Eye Occurrence in Sequential Satellite Infrared Imagery and Its Application to Improve Deep Learning‐Based Tropical Cyclone Intensity Estimation

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Tropical cyclone (TC) intensity estimation remains a critical yet challenging task, especially for intense storms that are often underestimated by both conventional and deep learning satellite‐based methods. Among various structural features, eye formation is the most distinct transformation during TC development and is closely linked to rapid
