Terms of Use

Who runs this site

This site is the personal academic and educational site of Xinru Qiu. It is not published by, and does not speak for, any employer or institution. Views expressed here are the author's own.

Content ownership

Original text, tutorials, illustrations, animations, the Healshu character, and the site's visual identity are © 2026 Xinru Qiu, all rights reserved. Public access to this site is not a grant of a license to reuse the material. What you may and may not do is set out on the licensing page, with the authoritative text in LICENSE.md.

Educational content, not professional advice

The tutorials describe computational methods for research use. They are teaching material: they simplify, they reflect the state of the field at the time of writing, and they may contain errors. Nothing here is clinical, diagnostic, or medical advice, and nothing here should be used to make patient-care decisions.

Code examples are illustrative. Verify parameters, package versions, and assumptions against the official documentation before relying on them for your own analysis. Corrections are welcome by email or as a GitHub issue.

Third-party names, tools, and links

Method names, software packages, and datasets referenced here belong to their respective authors and owners, and are named for identification and teaching purposes. Referencing a tool is not an endorsement, and it does not imply any affiliation with or sponsorship by its authors.

External links are provided for convenience. Their content is outside this site's control and is subject to the destination site's own terms.

Privacy

This site uses Google Analytics to understand which material is useful and where readers get stuck. It collects aggregate usage data such as page views, approximate region, and referring site. No accounts, no sign-in, and no personal data are collected by this site, and nothing is sold or shared for advertising. Analytics can be blocked with any standard browser setting or extension without affecting how the site works.

Availability and changes
