Abstract
Abstract Although both dipping boundary and anisotropy can cause significant energy in transverse component of receiver functions, they are distinguishable in the arrival time and period. According to different periodicities of transverse components, characteristic anisotropy or dipping boundary can be enhanced by weighted stacking method, and splitting parameters can be inferred from related waveform analysis. As an example, we studied crustal anisotropy near the Red River Fault using P to S converted phases of receiver function. The receiver functions are derived from four broadband digital seismic stations near the Red River Fault. The fast polarization direction is 132° with a time delay of 0.24s. The fast polarization direction in crust is consistent with tectonic line of this region but nearly perpendicular to the fast polarization direction of upper mantle, indicating that the crust and upper mantle may be de‐coupled near the Red River Fault.

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
