In this paper we demonstrate by numerical simulations based upon the Oregonator model for the photosensitive Belousov-Zhabotinskii reaction (PBZR) that the Winfree turbulence is suppressed by the interaction of the scroll ring with a confining Neumann boundary. Instead of the Winfree turbulence a stable scroll ring forms due to the boundary interaction. Furthermore, we will discuss the conditions under which boundar","authors_text":"Arash Azhand, Florian Buchholz, Harald Engel, Jan Totz, Rico Buchholz","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nlin.PS","submitted_at":"2014-01-31T10:34:06Z","title":"No-flux boundaries stabilize scroll rings in excitable media with negative filament tension"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1401.8119","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":"sha256:2c4b47e8492b15bc401b29c8295717be1f9431a9e2e5b227301a5677dee7b9a5","target":"record","created_at":"2026-05-18T03:00:36Z","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":"f13131997e28323830a4aa0c5cbf1911c2ffe424a32f78dad42faaf60eca17ec","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nlin.PS","submitted_at":"2014-01-31T10:34:06Z","title_canon_sha256":"c1737cee75bfc7833ea15c1ae4c64d7af9a9b2418dd0bfac876f4ac92acea97d"},"schema_version":"1.0","source":{"id":"1401.8119","kind":"arxiv","version":1}},"canonical_sha256":"3f8a7ba1145e1dbdd4b9c69e79fe8ee911516e1469e0f78e3dd0c1d1ad3c51c6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3f8a7ba1145e1dbdd4b9c69e79fe8ee911516e1469e0f78e3dd0c1d1ad3c51c6","first_computed_at":"2026-05-18T03:00:36.064492Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:00:36.064492Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"lzy9WGE6myScuRJWWxoaL0W16XN30zZpDt+3P5P/ZlBzgqpsCtbEkrWtiq6p3NX+o6IGh11iOcIWQ0kHzUOMCw==","signature_status":"signed_v1","signed_at":"2026-05-18T03:00:36.065192Z","signed_message":"canonical_sha256_bytes"},"source_id":"1401.8119","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2c4b47e8492b15bc401b29c8295717be1f9431a9e2e5b227301a5677dee7b9a5","sha256:b52b095eb610048918c0a5063d1c03737946bd32392cec0afebe1910c4eb2bb9"],"state_sha256":"f7b2956a5c3d56f9af7b0b03e681f09a1391d54b110b0c91a977d19cbe4b00f2"}
