Energy avalanches in the central plasma sheet
Bibliographic record
Abstract
The central plasma sheet (CPS) is simulated as a 1D cellular automaton. The system is driven deterministically and globally by a spatially non‐uniform energy loading (convection). Each node (a flux tube) evolves until one of two local instability criteria is exceeded. The unstable node releases a small amount of energy to the ionosphere and another small amount is distributed to its neighboring nodes. The partition between the two modes of energy distribution is the only random factor in the model. The energy redistribution relaxes the node deterministically to a stable state. The simulation suggests that a central plasma sheet driven in the above manner is in a self‐organized critical state, with energy avalanches obeying a scale‐free distribution. The avalanches, however, co‐exist with quasi‐periodic intermittencies manifested in ring‐current injection, which is correlated with strong CPS avalanches, and tailward energy ejection, which shows no apparent correlation in this aspect.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
