There are experiments on biopolymers like double stranded DNA, which twist and stretch single molecules to probe their elastic properties. It is known that thermal fluctuations play an important role in determining molecular elastic properties, but a\nfull theoretical treatment of the problem of twist elasticity of fluctuating ribbons using the simplest worm like chain model (WLC) remains elusive. In this paper, we approach this problem by taking first a mechanical approach and then incorporating thermal effects","authors_text":"Joseph Samuel, Supurna Sinha","cross_cats":["math-ph","math.MP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2010-11-30T09:04:03Z","title":"DNA Twist Elasticity: Mechanics and Thermal Fluctuations"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1011.6489","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":"sha256:0e4a572a18892df122345e92eec844dc68b58c33db65a2d32fea56379f9d26cd","target":"record","created_at":"2026-05-18T04:34:26Z","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":"e6d849ab2e0229b9e23f9990aa4b1878b5ff7cb9feb11e8bc9782f646bcd58a9","cross_cats_sorted":["math-ph","math.MP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2010-11-30T09:04:03Z","title_canon_sha256":"5cfe2c0ea5f52c04b69e27674869c92b8e5e77693d9bbfacbbb5531d60e6594e"},"schema_version":"1.0","source":{"id":"1011.6489","kind":"arxiv","version":1}},"canonical_sha256":"0b69fce83f1b7c56e59900d7accf9530f720a085ab790dfd4dda241ecfc7f99a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0b69fce83f1b7c56e59900d7accf9530f720a085ab790dfd4dda241ecfc7f99a","first_computed_at":"2026-05-18T04:34:26.805913Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:34:26.805913Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"iaylnPnLK/Ecx5QDk9sx/mCPc81cUTLS1ja9N/RhTBY6mMXQVg496DT6CaWA+caBIH/y297+EwHrI8bmCg2GDA==","signature_status":"signed_v1","signed_at":"2026-05-18T04:34:26.806567Z","signed_message":"canonical_sha256_bytes"},"source_id":"1011.6489","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0e4a572a18892df122345e92eec844dc68b58c33db65a2d32fea56379f9d26cd","sha256:8942a58470f26aa4307c7ec6f2d2224d322e08d340d0488405edb92bbdfc4a01"],"state_sha256":"76bdb66f14d94d896e88a34b95de120d0d40cc670483e5482442ed4c8fc30307"}
