- Description:
- The datasets associated with this deposit are micro-CT data. These data were generated to be better understand how diffusion iodine contrast enhanced (diceCT) CT scanning can differ amongst major groups of vertebrates. This study stained fish, mammals, reptiles, and amphibians with either H20-Lugol's iodine or Ethylic-Lugol's iodine and measured the differences in the resulting stained soft tissue contrast levels and iodine uptake.

- Description:
- The scanned proximal left humerus is part of an associated skeleton of the pterosaur Inabtanin alarabia, accessioned to Yarmouk University (YUPC-INAB-6-001–010) in the Hashemite Kingdom of Jordan. The specimen was collected from Late Cretaceous-aged sediments near Tal Inab in south-central Jordan, which is 34 km north of the current border with Saudi Arabia. For inquiries about access, please contact Jeff Wilson Mantilla ( wilsonja@umich.edu) or Iyad Zalmout ( izalmout@ksu.edu.sa). Casts of this and other elements of Inabtanin are available at the University of Michigan Museum of Paleontology.

- Description:
- The 3D model of the humerus was created from an isolated element that is referred to the pterosaur Arambourgiania philadelphiae. The element is accessioned to Yarmouk University (YUPC-RUSEIFA-1) in the Hashemite Kingdom of Jordan. The specimen was collected from Late Cretaceous-aged sediments at the Ruseifa Quarry in central Jordan. For inquiries about access to the specimen, please contact Jeff Wilson Mantilla ( wilsonja@umich.edu) or Iyad Zalmout ( izalmout@ksu.edu.sa). Casts of this element of Arambourgiania are available at the University of Michigan Museum of Paleontology.

- Description:
- The data herein resulted from a study documenting the characteristics of extratropical cyclones that pass through the Great Lakes Region (GLR) and how the cyclones are trending with time. All scripts used to create these data can be found in the Github repository https://github.com/abkenyon/GLStormTrends_2024. storm_track_slp_xxxx.npz - Structured numpy files containing all storm tracks identified over one cold season, regardless of whether the storm encountered the GLR, with the file name indicating the year on which the season ended. storm_composite_xxxx-xxxx.nc - NetCDF files containing one seasonal cyclone composite with different atmospheric variables. A composite is storm-centered, and covers a 20 degree square area.

- Description:
- Pharmaceutical synthesis has been a driving force behind advancements in the field of biocatalysis. In this paper, we report the further optimization of the heme protein YfeX for regio- and stereoselective carbene transfer reactions using mutagenesis to explore the role of important amino acids in the active site for catalysis. In this way, we identified YfeX variants that are efficient and selective carbene transferases towards primary and secondary amines, olefins, and indoles. Molecular Dynamic simulations reveal that mutations within the secondary coordination sphere induce distinct alterations in the conformation and electrostatic properties within the active site. These changes, in turn, affect substrate positioning both within the active site and at its entrance, which explains the distinct and sometimes surprising variations in selectivity observed experimentally between select YfeX variants. Our results show that the I230A single variant identified here is one of the most active N-H insertion catalysts known, producing >90% yields in only 1 hour (typical reaction times in the literature are 8 – 24 hours). On the other hand, the R232A variant catalyzes the C-H insertion of unprotected indole in 21% yield. The capacity to selectively act on unprotected indole offers a cost-effective, environmentally-friendly approach for late-stage functionalization of indoles and similar precursors in pharmaceuticals. In addition, YfeX is an efficient and fast biocatalyst that shows no structural degradation or heme loss during turnover, underscoring YfeX’s robustness as a viable biocatalyst for both industrial and academic applications.

- Description:
- This work characterized variability in the emitter geometry of a porous electrospray array thruster. It consists of raw topographic maps taken from the thruster, segmented versions of those maps that divide the measurement domain into individual sites within the array, and the geometric parameters describing each of those sites inferred by regressing a geometric model of an emitter against the data. It also includes copies of the computer code used to perform this analysis and plot the results, written in a combination of Python and MATLAB.

- Description:
- The SID dataset was curated to support advanced research in autonomous driving systems, particularly focusing on perception under adverse weather and lighting conditions. This dataset encompasses over 178k high-resolution stereo image pairs organized into 27 sequences, reflecting a rich variety of conditions such as snow, rain, fog, and low light. It covers dynamic changes in driving scenarios and environmental backgrounds, including university campuses, residential streets, and urban settings. The dataset is designed to challenge perception algorithms with scenarios such as partially obscured camera lenses and varying visibility, promoting the development of robust computer vision models. No specialized software or scripts are necessary for accessing the image data, as the files are provided in standard PNG format. However, researchers and developers may require their image processing and computer vision toolkits to utilize the dataset effectively in their work.
