More recently a natural generalization has been introduced in the biophysics literature to overcome the limits of the original model, namely to allow an excess of bases -- i.e. a different length of the two single stranded DNA chains -- and to allow slippages in the chain pairing. The increased complexity of the model is reflected in the appearance of configurational transitions when the DNA is in double stran","authors_text":"Giambattista Giacomin, Maha Khatib, Quentin Berger","cross_cats":["q-bio.BM"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.PR","submitted_at":"2017-03-30T07:50:32Z","title":"DNA melting structures in the generalized Poland-Scheraga model"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1703.10343","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":"sha256:3c5a238931ddfcc22c0baa27bd3e5b1686c570f20af8026114255df722abb97a","target":"record","created_at":"2026-05-18T00:47:37Z","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":"a73f5dc6393c3a8f154c050cec5c5264a9fd712de0652d8a8c6202b6db8803c5","cross_cats_sorted":["q-bio.BM"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.PR","submitted_at":"2017-03-30T07:50:32Z","title_canon_sha256":"a16a55fcfb6704444f5cd2aa063df4171bef3ff8eb858085f7d7ed5ec9f2b043"},"schema_version":"1.0","source":{"id":"1703.10343","kind":"arxiv","version":1}},"canonical_sha256":"397ef8355c84c00ed39029c44b73e5a432681ff48a0a3de667fe43caded6e514","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"397ef8355c84c00ed39029c44b73e5a432681ff48a0a3de667fe43caded6e514","first_computed_at":"2026-05-18T00:47:37.309136Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:47:37.309136Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bV+4mCNeXuN5TeQWcEIvEI9ZJjiZhIoU44qgkmPPVSUkJJ6sX5N1iFaTuu0WMVKcEhI7q3dig4SOGfGBnZ6BDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:47:37.309628Z","signed_message":"canonical_sha256_bytes"},"source_id":"1703.10343","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3c5a238931ddfcc22c0baa27bd3e5b1686c570f20af8026114255df722abb97a","sha256:4c5e925e54059180a61afd012317edb646426f2ef39ee44885c99e4b2f78759d"],"state_sha256":"86987c9c616b8c7b4c5a11901dadd7bb16b09bd84dbbd203095c48e2ec35e401"}
