Data and code associated with the publication: Full field stress response in 2-phase microstructures under dynamic loading
No full textThe dataset contains full-field stress responses for fiber-reinforced microstructure(s) exposed to external time-varying load path(s). The dataset contains variations in both spatial dimensions (fiber arrangement in microstructures) and temporal dimensions (external loading). A single simulation trajectory in the dataset consists of the full field stress response within a particular microstructure evaluated at equally spaced time-steps on a monotonically increasing external load path. This dataset can be potentially used for validation of analytical/data-driven models in computational mechanics research
Data and code associated with the publication: Building RNA concentration fields
No full textThis repository contains all raw data, images, and code associated with our paper (available on https://chemrxiv.org/engage/chemrxiv/article-details/6758a1f6f9980725cfa766e7
) and is scheduled for publication in a peer-reviewed journal.

Data associated with the publication: C3VDv2: 3D colonoscopy video dataset with enhanced realism
No full text3D computer vision techniques could improve the diagnostic value of colonoscopy, but the lack of 3D colonoscopy datasets for training and validation hinders their development. This paper introduces C3VDv2, a high-definition Colonoscopy 3D Video Dataset with enhanced realism designed to facilitate the quantitative evaluation of 3D colon reconstruction algorithms. 192 video sequences were captured by imaging high-fidelity phantoms from two colon anatomies. Ground truth depth, surface normals, optical flow, occlusion, six-degree-of-freedom pose, coverage maps, and 3D models are provided for 169 colonoscopy videos. Eight simulated screening colonoscopy videos acquired by a gastroenterologist are provided with ground truth poses. The dataset includes 15 videos featuring colon deformations for qualitative assessment. C3VDv2 elevates realism by incorporating diverse and challenging scenarios for 3D reconstruction algorithms commonly encountered during colonoscopy procedures, such as the presence of fecal debris, mucous pools, blood, debris obscuring the colonoscope lens, en-face views, and fast camera motion. The comprehensive nature of C3VDv2 offers a robust and diverse dataset for the quantitative and qualitative evaluation of 3D reconstruction algorithms. .

Code associated with the publication: Low levels of H5N1 HA and NA antibodies in the human population are boosted by seasonal A/H1N1 infection but not by A/H3N2 infection or influenza vaccination
No full textAn increase in the number of human cases of influenza A/H5N1 infection in the US has raised concerns about the pandemic potential of the virus. Preexisting population immunity is a key determinant for risk assessment and pandemic potential for influenza virus. Antibody responses against the bovine A/H5N1 hemagglutinin (HA) and neuraminidase (NA) proteins were measured among a population of influenza-vaccinated or influenza-infected individuals. Modest titers of bovine A/H5N1 HA-binding antibodies and low to undetectable neutralizing antibody responses were detected in a cohort of 73 individuals. Conversely, bovine A/H5N1 NA binding and neuraminidase-inhibiting antibody responses were comparable to those against a human A/H1N1 NA at baseline. Seasonal influenza vaccination failed to significantly increase antibody titers against both HA and NA glycoproteins of bovine A/H5N1. Recent infection with human A/H1N1 but not A/H3N2 viruses induced significant increases in bovine A/H5N1 neutralizing antibody, as well as increases in NA-binding and NA-inhibiting antibodies to bovine A/H5N1 NA. While the degree of protection afforded by these A/H5N1 cross-reactive antibodies is not known, incorporating NA or enhancing current seasonal vaccine formulations to increase NA-specific antibody responses may increase antibody breadth and protection against both seasonal and pandemic influenza viruses
