Abstract
ABSTRACT Electrical resistance tomography was used to evaluate liquid flow trough a 40 L model digester filled with wood chips. Tests were made with cooked and uncooked chips, both uncompressed and at two levels of chip compression (giving external liquid void fractions of 0.53, 0.43, and 0.33). The chips were stationary in all tests. Flow situations (symmetrical and asymmetrical liquid upflow, symmetrical liquid downflow) were studied with liquor recirculated through the downcomer-screen circulation loop. The creation of distinct liquor flow zones both above and below the screen section depended on the ratio of liquor flow in the downcomer-screen circuit to the axial liquor flow (either upflow or downflow) and did not depend on the level of chip compaction attained. Asymmetrical flows created by closing one-half of the screen set established nonuniform zones within the model digester. The significance of these findings for operating digesters is discussed.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
