Twinned calcite as an indicator of high differential stresses and low shock pressure conditions during impact cratering

Meteoritics &Planetary Science, Volume 58, Issue 9, Page 1287-1305, September 2023., 2023
Shock‐related calcite twins are characterized in calcite‐bearing metagranite cataclasites within crystalline megablocks of the Ries impact structure, Germany, as well as in cores from the FBN1973 research drilling.

The “suevite” conundrum, Part 2: Re‐examining the type locality at the Ries impact structure, Germany

Meteoritics &Planetary Science, Volume 59, Issue 10, Page 2622-2650, October 2024.
One of the most common types of allochthonous impactite produced in hypervelocity impact events is impact breccia that contains melt particles. In numerous terrestrial hypervelocity impact structures such melt‐bearing breccias have been termed “suevite,”

DEEP STRUCTURE, TECTONIC EVOLUTION AND HYDROCARBON POTENTIAL OF THE KALAMIT SWELL (NORTHWESTERN SHELF OF THE BLACK SEA) ACCORDING TO DENSITY MODELING DATA

Геологія і корисні копалини Світового океану
The deep structure, tectonic evolution and hydrocarbon potential of the Kalamitsky swell (КS) were determined using the density modeling method. In the research area, two megablocks separated by the North Euxine Fault are distinguished by crustal ...

Seismic reflection and topography insights into Ries crater diameter and megablock zone

Meteoritics & Planetary Science
Abstract Most of the extensive crater‐wide geophysical studies at the Ries impact structure were made decades ago when the origin of the structure was still being debated. Although it is one of the most studied impact structures, its internal structure was not imaged in high resolution until recently.

Scattered Mixture-of-Experts Implementation

arXiv.org
We present ScatterMoE, an implementation of Sparse Mixture-of-Experts (SMoE) on GPUs. ScatterMoE builds upon existing implementations, and overcoming some of the limitations to improve inference and training speed, and memory footprint.

A possible 5 km wide impact structure with associated 22 km wide exterior collapse terrain in the Alhabia–Tabernas Basin, southeastern Spain

Meteoritics &Planetary Science, Volume 58, Issue 10, Page 1512-1539, October 2023., 2023
Abstract The Tabernas–Alhabia Basin is a structural depression situated in the province of Almería, southeastern Spain. The basin is filled with Neogene, Pliocene, and Pleistocene sediments resting discordantly on a Paleozoic metamorphic basement. During the marine Tortonian sedimentation, a bed of breccia (Gordo megabed) was formed.

Educational interventions involving physical manipulatives for improving children's learning and development: A scoping review

Review of Education, Volume 11, Issue 2, August 2023., 2023
Abstract Physical manipulatives (PMs) are concrete objects used during hands‐on learning activities (e.g., building blocks, fraction tiles, counters), and are widely used in primary‐school teaching, especially during maths instruction. This scoping review collated studies that have examined the effectiveness of educational PM interventions with pre ...
