(Liang et al. 2025) Unfortunately we had to temporarily remove additional information as this was scraped by multiple AI companies who sell that data. However, these details, e.g. detailed descriptions (about less than half a page) are available for collaborators and contributors. Please contact us if you need any of this material. |
