- Description:
- These data came from research that was geared towards measuring the mass of the black hole in the galaxy NGC 4826. The data are line-of-sight velocity distributions (LOSVDs) inferred from high-spatial resolution stellar absorption line spectra of Hubble Space Telescope / Space Telescope Imaging Spectrograph (HST/STIS) data and lower-spatial resolution stellar absorption line spectra of Hobby-Ebberly Telescope / Low-Resolution Spectrograph (HET/LRS) data. These data can be used for kinematic analysis of the galaxy NGC 4826 (M64) including black hole mass estimation. The HST/STIS data span about one arcsec, and the HET/LRS data span about 90 arcsec.

- Description:
- THE DATA: Unfortunately, we are unable to share our data for this project. Since we were working with a vulnerable population (children), we were asked by Queens University Belfast’s IRB-equivalent to include language in the consent documents indicating that the data would not be shared outside of the research team. Thus, the datasets generated during and/or analyzed during the current study are not publicly available as participants were informed that no-one outside of the research team would have access to the research data when they signed their consent forms. Thus, we provide Stata, R and Mplus scripts used to generate all tables and figures reported in the paper. Since we cannot share the raw study data, most of these files cannot be run, but in the interest of transparency we include the scripts so that our code can be checked. Since a major portion of the paper is the LTA modeling, we took an additional step there and generated simulated data that allows the R+Mplus scripts to be run. These runnable scripts and the simulated data are contained in the subfolder LTA_code_EXEC.

- Description:
- Robotic models are useful for independently varying specific features, but most quadrupedal robots differ so greatly from animal morphologies that they have minimal evolutionary relevance. Commercially available quadrupedal robots are also prohibitively expensive for biological research programs and difficult to customize. Here, we present a low-cost quadrupedal robot with modular legs that can match a wide range of animal morphologies for biomechanical hypothesis testing. The Robot Of Theseus (TROT) costs ≈$4000 to build out of 3D printed parts and standard off-the-shelf supplies. Each limb consists of 2 or 3 rigid links; the proximal joint can be rotated to become a knee or elbow. Telescoping mechanisms vary the length of each limb link. The open-source software accommodates user-defined gaits and morphology changes. Effective leg length, or crouch, is determined by the four-bar linkage actuating each joint. The backdrivable motors can vary virtual spring stiffness and range of motion.
