Driven Translocation of Linked Ring Polymers through a Pore
Bibliographic record
Abstract
We have carried out a systematic computational investigation of the driven translocation dynamics of mutually entangled pairs of flexible polymers. Once closed into rings the entanglement is locked into topological links, and our results show that the presence of a topological (i.e., not removable) obstruction of this type at the pore dramatically slows down the translocation dynamics. The stalling time at the pore depends strongly on the complexity of the link type and corresponds to the time needed to squeeze the linked portion inside the pore. A notable feature is that unlike the translocation of knotted polymers, the passage of the portion of a two-component link that contains the essential crossings typically occurs when the translocation process is half completed. We claim that this difference can be exploited to distinguish knots from links by translocation experiments. These features should help to advance the interpretation and design of future translocation experiments aimed at probing the presence and amount of mutual entanglement in concatenated ring polymers.

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; a candidate call from one teacher head, not a consensus.
