Abstract
Linear-response dielectric theory is used to study the interaction potential between dust grains in a flowing plasma, taking into account the finite sizes and the asymmetric charge distributions of the grains. This potential can be divided into two parts: a screened Coulomb potential and a wake potential. The former is a short-ranged repulsive potential, while the later is a long-ranged oscillatory potential which acts only on trailing grains. Both the amplitude and wavelength of the wake potential depend on the Mach number. The grain size and the asymmetric charge distribution may affect the interaction potential in a significant way when the distances between grains are comparable with the grain size, or when the grain size is comparable with the plasma Debye length.

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
