If you are a researcher, correctly selecting pacs.10 or its subcodes is crucial for:
pacs.10 query --patientID "12345" --modality CT
Returns study UIDs, dates, and series descriptions.
It is important to address the transition. In 2016, the American Institute of Physics introduced the Physics Subject Headings (PhySH) system to replace PACS. PhySH is more flexible, faceted, and semantic. However, pacs.10 has not disappeared. pacs.10
For the next decade, any serious researcher must be bilingual: fluent in PhySH for new literature and fluent in PACS (especially .10) for the deep historical archive.
Before developing content or research in PACS.10, ensure background in: If you are a researcher, correctly selecting pacs
A breakthrough in solving nonlinear partial differential equations (PDEs) developed by a quantum gravity theorist might be the missing piece for a climate modeler. Without the pacs.10 tag, that paper would be buried in the "General Relativity" section. PACS.10 acts as a universal aggregator, allowing a mathematician working on eigenvalue problems to discover applications in plasma physics or quantum chemistry.
For the working scientist, knowing how to leverage pacs.10 in databases (like Crossref, Scopus, or arXiv.org) can save hundreds of hours of literature review. Returns study UIDs, dates, and series descriptions
On arXiv.org:
While arXiv uses its own subject classification, many authors still include legacy PACS codes in their metadata. Searching for "pacs: 10" in the abstract or full-text search will return papers focused on mathematical methods. A smarter search query is:
cat:physics.comp-ph OR cat:math-ph combined with "PACS: 10"
In Scopus and Web of Science:
These databases allow direct filtering by PACS code. Use pacs.10 as a filter, then refine by year or journal. You will notice that high-impact journals like the Journal of Computational Physics, Physical Review E, and Computer Physics Communications are overrepresented in this category.
Pro-Tip for Authors:
If you are writing a paper that introduces a new numerical method (e.g., a symplectic integrator for Hamiltonian systems) or a novel mathematical technique (e.g., a new transform for solving the heat equation), explicitly include PACS: 10.xx in your manuscript metadata. This ensures that your work is indexed not just for your specific application field but for the entire community of computational physicists.
