A parametric study is carried out with respect to three major parameters: blowing pressure, embouchure and nonlinear losses coefficient.The model exhibits the well-known effect of reducing the maximum blowing pressure until the oscillations stop (extinction threshold) when nonlinear losses increase.Furthermore, the stability analysis also shows that increasing nonlinear losses increases the mini","authors_text":"Christophe Vergez (LMA), Micha\\\"el Jousserand, Nathan Szwarcberg (LMA), Tom Colinot","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.class-ph","submitted_at":"2024-11-27T10:06:18Z","title":"Oscillation threshold of a Raman clarinet with localized nonlinear losses at the open end"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2411.18185","kind":"arxiv","version":4},"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":"sha256:4e3a848aec19386c511808f2a0f56120c4871e29f68a0da31039eab882eab50c","target":"record","created_at":"2026-07-05T10:40:14Z","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":"a8329cc5b04b5504128f7bfcf908654ee3ec42438566c9e79ce32b282b9fae4f","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.class-ph","submitted_at":"2024-11-27T10:06:18Z","title_canon_sha256":"4fa36ece61401a923421ff38c72a50ff0d79baa23bbaeb65f2204ef98953c1f8"},"schema_version":"1.0","source":{"id":"2411.18185","kind":"arxiv","version":4}},"canonical_sha256":"06a276f837d92b63b78d4a5718f89f270fe3a94c08211657b89189d0f8cda7dc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"06a276f837d92b63b78d4a5718f89f270fe3a94c08211657b89189d0f8cda7dc","first_computed_at":"2026-07-05T10:40:14.476912Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:40:14.476912Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"jc0QOvAtvcb4pyGm4fYfLjTPw5rNgW0NAybgMZdfYpAzUd8axSmeONZxx2a31IcV8aQmi5fDWjaW6C8vhV5lCg==","signature_status":"signed_v1","signed_at":"2026-07-05T10:40:14.477388Z","signed_message":"canonical_sha256_bytes"},"source_id":"2411.18185","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4e3a848aec19386c511808f2a0f56120c4871e29f68a0da31039eab882eab50c","sha256:28df8857c1397f413349eaec47486599ec0ab9d564eba09d760fb4a1946a7df7"],"state_sha256":"c6b7043efb3666c43058cb149cdd9afdd868e63396c029db456a2d8f6451f154"}
