Dynamics of laser induced thermoelastic expansion of native and coagulated ex-vivo soft tissue samples and their optical and thermo-mechanical properties
Bibliographic record
Abstract
The interferometric measurement of laser induced thermoelastic expansion of tissue samples can be used to estimate their optical, thermal and mechanical properties. This method was used to assess the Gruneisen coefficient and optical attenuation depth for native and coagulated ex-vivo bovine liver and porcine kidney samples. The results demonstrate decreases of 54% and 60% in the optical attenuation depth in bovine liver and porcine kidney after coagulation, respectively. The Gruneisen coefficient of native porcine kidney was determined to be 58% smaller (p < 0.05) that native bovine liver. The measured Gruneisen coefficients for native and coagulated ex-vivo porcine kidney were 0.07 ± 0.03 and 0.105 ± 0.02, respectively, whereas the Gruneisen coefficients for native and coagulated liver were 0.126 ± 0.036 and 0.127 ± 0.04, respectively. Our measurements indicate significant inter sample variability due likely to inherent variations in tissue optical absorption and surface preparation.

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.
