Nice line drawing. Could be interesting to use a plotter to print those drawings

TechRxiv (pronounced "tech archive") is an open, moderated preprint server for unpublished research in the areas of engineering, computer science, and related technology.

Les preprints rédigés sur Authorea finissent dans techRxiv une fois qu'ils sont prêts à être publié dans une revue.

VeriXiv (pronounced very-kive) is a verified preprint server, enabling the rapid availability of new research findings. Preprints are the version of a research paper shared prior to peer review and publication in a journal. Unlike many preprint servers, VeriXiv will conduct a series of rigorous pre-publication checks to support research integrity.

VeriXiv supports researchers in complying with the Gates Foundation’s refreshed Open Access policy that requires all their funded research to be made available as a preprint from January 2025.
