In our experiments, these chiral structures arise with well-defined probabilities P_H controlled by conditions such as e.g., the initial concentration of the reagents. We develop a model which describes the observed experimental trends. The results suggest that P_H is determined by a delicate interplay among the time and length scales related to the front and to the unstable precipitation modes and, furthermore, the noise amplitude also plays a quantifiable role.","authors_text":"Ferenc Molnar Jr, Istvan Lagzi, Shibi Thomas, Zoltan Racz","cross_cats":["cond-mat.soft"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2013-02-20T15:34:20Z","title":"Probability of the emergence of helical precipitation patterns in the wake of reaction-diffusion fronts"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1302.4997","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:f9e1485b03d26655477ef4e74a3baba22986f7ddf6ac989a832d0da01751c651","target":"record","created_at":"2026-05-18T03:33:00Z","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":"12577228b24c5fe15780e4c19480eebe945087bae40e66c7e54e482500a7e31c","cross_cats_sorted":["cond-mat.soft"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.stat-mech","submitted_at":"2013-02-20T15:34:20Z","title_canon_sha256":"de3239a08e904ff1500482ebde89c2318ffdcf21d0bb81eaba6be0d62f45516d"},"schema_version":"1.0","source":{"id":"1302.4997","kind":"arxiv","version":1}},"canonical_sha256":"b38c9e977eedd3e6dcecdaf36911fa0c9f490d69b8a05177f21b9bb8c4f52882","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b38c9e977eedd3e6dcecdaf36911fa0c9f490d69b8a05177f21b9bb8c4f52882","first_computed_at":"2026-05-18T03:33:00.480719Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:33:00.480719Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"L1ALGdcb7XEQCCb8GZnLMs0w976zwCYTd7GKQdnRxXV7e8GITn8sFNCElDG8OWHpNMgLmC+xq7qi0XMD+3cSBA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:33:00.481548Z","signed_message":"canonical_sha256_bytes"},"source_id":"1302.4997","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f9e1485b03d26655477ef4e74a3baba22986f7ddf6ac989a832d0da01751c651","sha256:6732e8a3b2d82cff6ecb679c5f320b07b82b2e7926b6a9a1d27ce44c1f2a481e"],"state_sha256":"b103c35cf397b9c79a78a5ef6d9e0596154bc1572335f3e14eadff15efb0042a"}
