However, structures are strikingly different in the near field, where elasticity-driven streaks affect the dynamics in the potential core of the viscoelastic planar jet, modifying the bulk flow and interacting with the flow instability. The analysis of the polymer field reveals stretched polymer filaments and centre-mode structures, which support the implication of the near-field streaks on sustaining elastic turbulence in three-dimensional viscoelastic planar jets.","weakest_assumption":"That the spatio-temporal Koopman decomposition applied to the simulated velocity and polymer fields fully captures the dominant mechanisms without significant truncation error or missing modes that could alter the interpretation of near-field streaks as the primary sustainer of elastic turbulence."}},"verdict_id":"07420733-0422-4005-a081-f943d78b5855"}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:f6acf425b7b0aa5632a484bd166ca2b534ea2d5201c99c28085e0c3f9b142abe","target":"record","created_at":"2026-06-03T14:05:25Z","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":"80c26968bcd1927553ddb4021be47115dee18c2c4b219d0290d9870e29641d9d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.flu-dyn","submitted_at":"2026-04-29T04:36:59Z","title_canon_sha256":"eb0ac618bb818e7b06f69b8d923d4c01b7e20cb5082cc5045e677abf4cb04331"},"schema_version":"1.0","source":{"id":"2604.26291","kind":"arxiv","version":1}},"canonical_sha256":"6bb02f1d9c8a0811ed4f65cbd468e425bbdfdfe53f6bef95f6e06cf017d0c411","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6bb02f1d9c8a0811ed4f65cbd468e425bbdfdfe53f6bef95f6e06cf017d0c411","first_computed_at":"2026-06-03T14:05:25.251560Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-03T14:05:25.251560Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"uNp6XSz6y42kCXY8GxIhQUNa5ydZEHrYdHBuffpYljc7FlLaoASAZvyfzJC9cVjxucFti3j9oZD8uWN5Ydj/Bg==","signature_status":"signed_v1","signed_at":"2026-06-03T14:05:25.251968Z","signed_message":"canonical_sha256_bytes"},"source_id":"2604.26291","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f6acf425b7b0aa5632a484bd166ca2b534ea2d5201c99c28085e0c3f9b142abe","sha256:58226852180864a44c9106f34b13c0ec1728fb2ec0dfdb149b516152f1a00161"],"state_sha256":"a1c341ecc57c3752863a5312155ddb57601a0138d3aa2692337b35883b15d37a"},"bundle_signature":{"signature_status":"signed_v1","algorithm":"ed25519","key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signature_b64":"CHt0p/JcrxjwgPU+3P/AfMTeH4SqVYK3QAKs1ZbZ5BTj0B9PP5YOoEGPFBkExHeNIH16GOvsFT8zEdvkgHs6Aw==","signed_message":"bundle_sha256_bytes","signed_at":"2026-08-03T20:12:18.040226Z","bundle_sha256":"69915583f910c145f0703ff655642751b9fd90fa24f64d48f9d591291bba7b84"}}
