It is usually believed that these two regimes are driven either by chemical and thermal fields, or through non-local mechanical interactions. Here, we show explicitly that local mechanical interactions regulates the stability and reversibility of the cooperative/non-cooperative melting transition, which is described by a single parameter depending on an internal length scale. Our theory is applicable to a wide range of biological examples such as DNA, protein secondary structures, and the m","authors_text":"Alain Goriely, Giuseppe Florio, Giuseppe Puglisi, Luca Bellino","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.soft","submitted_at":"2023-02-07T17:24:06Z","title":"Cooperative melting in double-stranded peptide chains through local mechanical interactions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2302.11402","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":"sha256:8ea378ff3ec2d4cb55600d706c2ff2a62aa87a0f146747482ac0d086c9e84d35","target":"record","created_at":"2026-07-05T05:44:43Z","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":"6ce2bfae81c5636d02d796e20d10847d10a62f730e7f256ee961e19931fa5a1e","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cond-mat.soft","submitted_at":"2023-02-07T17:24:06Z","title_canon_sha256":"47a44468a62e723f56dda175b9dae7925941d90f586bb8fed61d51ec139b418f"},"schema_version":"1.0","source":{"id":"2302.11402","kind":"arxiv","version":1}},"canonical_sha256":"04c88f67c92be3b8912aaa561e504f1b012ca32b155dd56e156a7dd5e03ea46c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"04c88f67c92be3b8912aaa561e504f1b012ca32b155dd56e156a7dd5e03ea46c","first_computed_at":"2026-07-05T05:44:43.293742Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:44:43.293742Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"vwtx2fnFqDA5fGOXk5vLc7qXh4DOtRLDcxcN0Y9R6f1mp/P9kQB70RoPhyD0iCidyXCGc7WKTDzvm0PQFlWbAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T05:44:43.294264Z","signed_message":"canonical_sha256_bytes"},"source_id":"2302.11402","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8ea378ff3ec2d4cb55600d706c2ff2a62aa87a0f146747482ac0d086c9e84d35","sha256:1567c981c2370c9b05da65901948673b3a1d214761f18a091516575f53d99676"],"state_sha256":"c59c87fbb54b13c3d7555b93e2ddb3bd10acccfb484aed22a8c64372b765ec16"}
