Changes in Physical Properties of Yellow Birch Below and Above the Fiber Saturation Point
Bibliographic record
Abstract
Two experimental techniques were used to perform moisture sorption tests at 25C on specimens of yellow birch sapwood.The first used saturated salt solutions (from 33% to 90% relative humidity), and the second used the pressure membrane method (above 96% relative humidity).These sorption tests were combined with dimensional measurements and perpendicular-to-the-grain tangential compression tests.Results showed that at equilibrium moisture content, radial, tangential, and volumetric shrinkage, as well as changes in transverse strength, occur above the fiber saturation point.This behavior can be explained by the effect of hysteresis at saturation on wood properties.This hysteresis indicates that loss of bound water takes place in the presence of liquid water, which contradicts the concept of FSP.The initial equilibrium moisture content at which bound water is removed from yellow birch was about 41%.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
