Though often rotated so as to produce thrust, some species of bacteria such Spiroplasma, Rhodobacter sphaeroides and Spirochetes induce movement by deforming a helical-shaped body. Recently, artificial devices have been created which also generate motion by deforming their helical body in a non-reciprocal way (Mourran et al., Adv. Mater., 29, 1604825, 2017). Inspired by these systems, we investigate the transport of a deforming helix within a viscous fluid. Specifically, we consider a swimm","authors_text":"Ahmed Mourran, Eric Lauga, Hang Zhang, Lyndon Koens, Martin Moeller","cross_cats":["cond-mat.soft","physics.flu-dyn"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.bio-ph","submitted_at":"2018-10-22T09:26:42Z","title":"The swimming of a deforming helix"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1810.09148","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":"sha256:70706235ef49a9ffefeed67769d957c13816ff8aa84b80d360c8ab3a4fe16daa","target":"record","created_at":"2026-05-18T00:02:40Z","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":"973c27a441303616e12ebeff7bb459c30d7a3ed02cda9a385b1a15323cc11788","cross_cats_sorted":["cond-mat.soft","physics.flu-dyn"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.bio-ph","submitted_at":"2018-10-22T09:26:42Z","title_canon_sha256":"1445b44e722741d5ef8b47178a239a00da730d610dfcd10c171f303e587386ab"},"schema_version":"1.0","source":{"id":"1810.09148","kind":"arxiv","version":1}},"canonical_sha256":"4dd7eea73bd424e4c17a82df485b91ddfcc80a720ba4c35c275881904fde1237","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4dd7eea73bd424e4c17a82df485b91ddfcc80a720ba4c35c275881904fde1237","first_computed_at":"2026-05-18T00:02:40.935739Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:02:40.935739Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"41UXljmMuIFp2c7RuZopcye2A0eX4W+p0PfzTmKoq6Ckb4HrneGKL5O0s9KnByAXePOVkPN+sdsp0AAF5hXEAw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:02:40.936181Z","signed_message":"canonical_sha256_bytes"},"source_id":"1810.09148","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:70706235ef49a9ffefeed67769d957c13816ff8aa84b80d360c8ab3a4fe16daa","sha256:863a2006d7e72ce4eec29bb70b2c24dc22ad3ac3904330d4d0507b22c09252a5"],"state_sha256":"ae2e123eb1c6ba157cd4b5a612fee909df2d8b81208c6b8b7790fec759d99c86"}
