title: The evolution of brain size through the end-Permian mass extinction

description: The genus Lystrosaurus, a mammalian ancestor, is famous for surviving the worst extinction of all, the end-Permian mass extinction. The fossil record chronicles the survival of this genus before, through, and after the extinction, offering a unique opportunity to unravel its survival strategies. Many aspects of Lystrosaurus paleobiology have been studied, except the evolution of its brain size. The brain is an energy expensive organ, which puts a high selective pressure on it when resources become scarce; yet, it is also the seat of cognition, and may help to behaviourally adapt to a rapidly changing environment. As such, brain size may decrease or increase depending on the evolutionary response to mass extinction events. Documenting variations of the brain size in Lystrosaurus through the end-Permian mass extinction will shed new light on the evolutionary response of the central nervous system to high stress conditions, and how these dramatic events have shaped the mammalian brain.

title: Results of geochemical analysis and modeling of mafic xenoliths in a petit-spot volcano from KR04-08 cruise

description: This dataset includes the whole-rock and mineral chemistry, Sr–Nd–Pb isotopic ratios, and petrography of basaltic, doleritic, and gabbroic xenoliths in a petit-spot volcano on the northwestern Pacific Plate. It provides geochemical and isotopic data that characterize the deeper lithologies of in situ old oceanic crust, offering insights into its formation at the fast-spreading Izanagi–Pacific Ridge (130–140 Ma) and subsequent evolution. This dataset is linked to Mikuni et al. (2025) Marine Geology.

title: X-ray Computed Tomography Case Study: Triangle and Pentagon Datasets with Various Sizes, Scales, and Noise Levels

description: Description

Sample information:

The dataset consists of two laser-cut objects made from a 6-mm-thick transparent plastic material called acrylate. The objects have triangular and pentagonal shapes, each containing 12 samples with varying sizes. The right-angle edges of the triangular samples range from 2.8 cm to 4.0 cm, while the edges of the pentagonal samples range from 2.5 cm to 3.0 cm. Each scanning session involved different placements of the objects, resulting in variations in rotation and translation.

Scanner information

The dataset is acquired in the FleX-ray Laboratory, developed by TESCAN-XRE, located at CWI in Amsterdam. The CT scanner consists of a cone-beam microfocus polychromatic X-ray point source, and a 1944x1536 pixel, 14-bit, flat detector panel (Dexela1512NDT). Full details can be found in [Coban 2020].

Scanning geometry

A Region-of-Interest (ROI) scanning approach was used to acquire projections with dimensions of 956 X 10 pixels. The source-to-object and detector-to-object distances were both set to 225 mm. 

Scanning settings

A peak voltage of 90 kV was used. An exposure time of 80 ms per projection was applied, and the source spectrum was shaped using filters consisting of 0.1 mm zinc, 0.2 mm copper, and 0.5 mm aluminum. A total of 3601 projections were acquired. To create a dataset with three noise levels, three emission currents were used: 600 μA, 300 μA, and 100 μA. The lower emission current (100 μA) produced data with higher noise levels. Finally, 12 groups of projections were acquired for each shape and each noise level, resulting in a total of 48 groups of projections. 

Reconstruction

The script fan_beam_reconstruction.py uses the ASTRA toolbox [Aarle 2015, Aarle 2016] to reconstruct the dataset. It focuses on the middle row of the detector to approximate fan-beam geometry.

File name description

For example, Triangle_600 represents triangular samples scanned at an emission current of 600 μA. Files within that folder—like Triangle_600_1—denote individual samples (in this case, the first sample).
