Crater morphology in sandstone targets: The MEMIN impact parameter study: Experimental impact crater morphology

, 2013
Hypervelocity (2.5–7.8 km s−1) impact experiments into sandstone were carried out to investigate the influence of projectile velocity and mass, target pore space saturation, target-projectile density contrast, and target layer orientation on crater size ...

Out in the cold? A review of Early Middle Palaeolithic settlements in northern Central Europe, age data and geological preconditions for site formation and preservation

Boreas, EarlyView.
The characteristics of settlement of Neanderthals in northern Central Europe during the earlier phases of the Middle Palaeolithic (Marine Isotope Stage 8–6) have been a matter of debate for decades, specifically regarding the population dynamics at such latitudes during the coldest phases. In this paper, we review the known archaeological record of the

Terrain Synthesis and Authoring based on Iso‐Contours

Computer 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.

Stability of granular media impacts morphological characteristics under different impact conditions

Open Astronomy
In planetary surfaces, oblique impact events are commonplace, and their study holds significant importance for understanding planetary impact processes and aiding in the design of landers and impactors.

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

Cladistics, 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.

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

Remote 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.
