Domain-specific

• Group contribution method
  • The transferable element is the parameterized group description, not a universal claim that each fragment contributes one fixed independent number.
• UNIQUAC
  • … structural r and q parameters, binary interaction parameters and temperature dependence, combinatorial and residual equations, composition convention and phase-equilibrium use are explicit. to An applied instance preserves the same invariant under changed scale, notation, dataset, jurisdiction, or implementation..

Verification

Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.

Does it back the claim? Not recorded. Neither this nor any other of the 2 citations of this work carries a recorded support check.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
