Biochar alters hydraulic conductivity and inhibits nutrient leaching in two agricultural soils: AS800, AS500, SW500 biochars
Bibliographic record
Abstract
X-ray microcomputed tomography data collected at the advanced light source beamline 8.3.2 of almond shell and softwood biochars hydropyrolyzed at 500 C and an almond shell biochar gasified at 800 C. Gross morphological differences among AS500, AS800 and SW500 were visualized by X-ray micro-computed tomography (X-ray microCT) at the Lawrence Berkeley National Laboratory Advance Light Source on beamline 8.3.2 using a beam energy of 21 KeV. 1025 projections were acquired using continuous tomography mode with a 4x objective, for a final pixel size of 1.7 µm. Images were reconstructed using gridrec methods via TomoPy and Xi-CAM . Image analysis was completed in Dragonfly, a 3d image analysis software free for non-commercial use (Object Research Systems, Canada).
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
How this classification was reachedexpand
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; both teacher heads agree on what is shown here.
