Terrain Synthesis and Authoring based on Iso‐Contours

open access: yesComputer Graphics Forum, EarlyView.
Abstract Digital terrains are central to realistic landscape depiction, yet authoring tools must balance perceptual realism with intuitive artistic control. We propose a compact vector‐based representation that models terrain as nested iso‐contours, inspired by geomorphology and cartography.

Quantitative Research on the Morphological Characteristics of Lunar Impact Craters of Different Stratigraphic Ages since the Imbrian Period

open access: yesRemote Sensing
Impact craters serve as recorders of lunar evolutionary history, and determining the stratigraphic ages of craters is crucial. However, the age of many craters on the Moon remains undetermined.

Budding speciation, mitochondrial capture and introgression between surface and cave lineages in the Asellus aquaticus species complex

open access: yesCladistics, EarlyView.
Abstract Replicated pairs of ancestral and evolutionarily derived populations provide opportunities to test hypotheses about the deterministic laws of evolution. The Asellus aquaticus species complex is an invertebrate model system with several independent surface‐to‐cave transitions and a complicated and unresolved evolutionary history.

Hydrothermal activity generated by impact melt emplacement on the rim of Ritchey crater, Mars

open access: yesNature Communications
Impact-induced hydrothermal systems have the potential to sustain long-lived aqueous environments throughout the history of Mars, yet their nature and distribution are not well-understood.

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement

open access: yesGeophysical Monograph Series, Page 27-82., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Resolving Micrometre‐Scale Zircon Growth in Silicic Systems by 7 μm LA‐MC‐ICP‐MS U‐Pb Dating: Linking Petrology and Geochronology in Silicic Volcanic and Granitic Rocks from Victoria, Australia

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points 7 μm spot‐diameter LA‐MC‐ICP‐MS analyses yield accurate zircon U‐Pb ages. 1013 Ω amplifier resistors improve low‐signal Pb measurements. Saturn correction protocols minimise down‐hole fractionation effects. We present a systematic evaluation of high spatial‐resolution zircon U‐Pb dating using a Thermo Scientific Neoma multi‐collector ICP‐MS ...

Bimekizumab efficacy using IHS4 outcomes in hidradenitis suppurativa: Results from BE HEARD I and II

open access: yesJournal of the European Academy of Dermatology and Venereology, EarlyView.
The majority of bimekizumab‐treated patients shifted from severe to mild and moderate IHS4 stages, and nearly 25% achieved an IHS4 of 0 by Week 48. Bimekizumab led to clinically meaningful improvements across IHS4 outcome measures. These data highlight an opportunity to address the need for effective treatments against draining tunnels.
