Yields of 3D magnetorotational supernova models in Zha et al. 2024
<p>These tables contain the nucleosynthetic yields from magnetorotational supernovae calculated by Zha, Mueller, Powell (2024), arXiv: 2403.02072. The name of the tables indicates that the models has an initial progenitor mass of 39 solar masses. B0, B10, B12 imply the initial magnetic-field strengths of 0, 10^10 and 10^12 gauss with detailed field configuration given by Equation (1) of the accompanying paper. Each table has three columns, which displace the atomic number (1st column), mass number (2nd column) and absolute mass in the unit of a solar mass (3rd column), corresponding to each isotope in the rows. </p>

3D models of Artibeus jamaicensis and Rhinolophus pusillus hyoid apparatus and tympanic bones
<p>The morphology of the stylohyal-tympanic bone articulation found in laryngeally echolocating 7 bats is highly indicative of a function associated with signal production. One untested hypothesis is that 8 this morphology allows the transfer of a sound signal from the larynx to the tympanic bones (auditory 9 bulla) via the hyoid apparatus during signal production by the larynx. We used µCT data and finite 10 element analysis (FEA) to model the propagation of sound through the hyoid chain into the tympanic 11 bones to test this hypothesis. We modeled sound pressure (dB) wave propagation from the basihyal to the 12 tympanic bones, vibratory behavior (m) of the stylohyal – tympanic bone unit, and the stylohyal and 13 tympanic bones when the stylohyal bone is allowed to pivot on the tympanic bone. Sound pressure wave 14 propagation was modeled using the harmonic acoustics solver in ANSYS and vibratory behavior was 15 modeled using coupled modal and harmonic response analyses in ANSYS. For both analyses (harmonic 16 acoustics and harmonic response), the input excitation on the basihyal and thyrohyals was modeled as the 17 estimated pressure (Pa) imposed by the collision of the vibrating thyroid cartilage of the larynx against 18 these bones during signal production. Our models support the hypothesis that this stereotypical hyoid 19 morphology found in laryngeally echolocating bats can transfer sound to the auditory bullae at an 20 amplitude that is likely heard for the species Artibeus jamaicensis and Rhinolophus pusillus</p>

Data from: Ellipsoid segmentation model for analyzing light-attenuated 3D confocal image stacks of fluorescent multi-cellular spheroids
In oncology, two-dimensional in-vitro culture models are the standard test beds for the discovery and development of cancer treatments, but in the last decades, evidence emerged that such models have low predictive value for clinical efficacy. Therefore they are increasingly complemented by more physiologically relevant 3D models, such as spheroid micro-tumor cultures. If suitable fluorescent labels are applied, confocal 3D image stacks can characterize the structure of such volumetric cultures and, for example, cell proliferation. However, several issues hamper accurate analysis. In particular, signal attenuation within the tissue of the spheroids prevents the acquisition of a complete image for spheroids over 100 micrometers in diameter. And quantitative analysis of large 3D image data sets is challenging, creating a need for methods which can be applied to large-scale experiments and account for impeding factors. We present a robust, computationally inexpensive 2.5D method for the segmentation of spheroid cultures and for counting proliferating cells within them. The spheroids are assumed to be approximately ellipsoid in shape. They are identified from information present in the Maximum Intensity Projection (MIP) and the corresponding height view, also known as Z-buffer. It alerts the user when potential bias-introducing factors cannot be compensated for and includes a compensation for signal attenuation.
Functional and ecomorphological evolution of orbit shape in Mesozoic archosaurs is driven by body size and diet: Geometric morphometric data, 3D models (stl files), FEA models (Hypermesh, Abaqus files)
<p class="MsoNormal">The orbit is one of several skull openings in the archosauromorph skull. Intuitively, it could be assumed that orbit shape would closely approximate the shape and size of the eyeball resulting in a predominantly circular morphology. However, a quantification of orbit shape across Archosauromorpha using a geometric morphometric approach demonstrates a large morphological diversity despite the fact that the majority of species retained a circular orbit. This morphological diversity is nearly exclusively driven by large (skull length > 1000 mm) and carnivorous species in all studied archosauromorph groups, but particularly prominently in theropod dinosaurs. While circular orbit shapes are retained in most herbivores and smaller species, as well as in juveniles and early ontogenetic stages, large carnivores adopted elliptical and keyhole-shaped orbits. Biomechanical modeling using finite element analysis reveals that these morphologies are beneficial in mitigating and dissipating feeding-induced stresses without additional reinforcement of the bony structure of the skull.</p>
