The emergence of a regime of negative differential mobility induced by topological interactions between the rings and the substrate is the key mechanism for selective sieving of circular polymers with distinct flexibilities. A simple model accurately describes the sieving process observed in molecular dynamics simulations and yields experimentally verifiable analytical predictions, which can be used as a reference guide for improving filtration procedures of ci","authors_text":"Davide Michieletto, Enzo Orlandini, Marco Baiesi, Stefano Iubini","cross_cats":["q-bio.BM"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2018-11-19T20:48:35Z","title":"Topological Sieving of Rings According to their Rigidity"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1811.07970","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:60c77be57fb1497d58f3a4812bd37e6505f7cf4b4b476a9d7307f57ddd51a777","target":"record","created_at":"2026-05-18T00:00:17Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"adc715d93547266dd7d78bf2cbd5a12bfeb49c6a336319897e2dcb2aa57d49e2","cross_cats_sorted":["q-bio.BM"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2018-11-19T20:48:35Z","title_canon_sha256":"021c8c5d38695ccf0c872f48948bd6f2238b37491cc025e07e0535c0a0202adc"},"schema_version":"1.0","source":{"id":"1811.07970","kind":"arxiv","version":1}},"canonical_sha256":"270c7f07182eabdfad02115c2df89a974b8c666deed8f43cca779f9984be2358","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"270c7f07182eabdfad02115c2df89a974b8c666deed8f43cca779f9984be2358","first_computed_at":"2026-05-18T00:00:17.239700Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:00:17.239700Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"dzPGUv0/jQstBSX5jVxiBg39YVqSVVmYnrhVokgUIEaQsSCfQADdZQJjyAa6sCE5tGvsrcEWfchnosAdP9wjAw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:00:17.240326Z","signed_message":"canonical_sha256_bytes"},"source_id":"1811.07970","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:60c77be57fb1497d58f3a4812bd37e6505f7cf4b4b476a9d7307f57ddd51a777","sha256:1370239b22688db39c9b694251725371bba70dc7cbc381433f4235c628056a70"],"state_sha256":"4e77c2f94fd9b27f695dad1a7e382f1ad62c1d60b5e689dadae359478a4a32a9"}
