Incoherent inelastic neutron-scattering studies of the structure of water associated with DNA and gelatin
Bibliographic record
Abstract
Incoherent inelastic neutron-scattering spectra of DNA and gelatin samples with different hydration levels were measured with the TOSCA spectrometer at ISIS, Rutherford Appleton Laboratory. Comparison with the spectra of different ice phases shows that for water contents up to 0.75 g water/g DNA and 0.5 g water/g gelatin the optical region (2050 meV) is almost featureless, similar to high-density amorphous ice (HDA). The librational band is shifted to lower energy transfers and its edge at 55 meV matches again the spectrum of HDA ice. For water contents of 1 g water/g DNA and 0.75 g water/g gelatin resemblance to spectra of ice Ih and low-density amorphous ice (LDA) is obvious. PACS Nos.: 61.12Ex, 82.39Jn

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
