Editor’s rationale

Heuristic triage from title and abstract text only, not a reading of the paper. Cues found: novelty (contrary to expectation, open problem).

How the score was computed

rank-2026-10-18

Score█████░░░░░5.1

Score = 10 × (50% × adjusted merit / 10 + 25% × attention + 25% × freshness)

Desks place stronger verdicts first, then use this score to order work within the same verdict.

Merit: 3.5 / 10; Weighted rubric, evidence-gated.
Adjusted merit: 3.9 / 10; Shrunk toward the desk prior by editor confidence (30%).
Attention: 29%; Citations, upvotes, points, mentions.
Freshness: 98%; Half-life decay since publication.

No attention signals recorded yet.
