Recent studies have shown that the physiology of bacteria can be significantly altered when subjected to shear and/or extensional stresses. With this motivation, we perform experiments to understand the vortex dynamics involved during the pinch-off process in a cross flow droplet generator, using particle image velocimetry (PIV) to visualize the vortical structures and to quantitatively measure the asso","authors_text":"Cameron Tropea, Saini Jatin Rao, Saptarshi Basu, Shubhadeep Mandal, Siddhant Jain","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.flu-dyn","submitted_at":"2025-05-24T05:47:20Z","title":"Vortex Dynamics During Pinch-off of Micro-Droplets"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2505.18528","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":"sha256:568ea87d6ea0680bd96b3bc663f12b658e7c66128e6a044f2b306ceb7715608d","target":"record","created_at":"2026-07-05T11:08:47Z","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":"0b4c5a4bc8a56a9a584bd773e16eff740d6b8cca79e7ee9af74e326f93aee753","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.flu-dyn","submitted_at":"2025-05-24T05:47:20Z","title_canon_sha256":"8e6e5a98f24e38c6976be75ebfc4d836079c772a39b7c1d08ed7109213bd5cab"},"schema_version":"1.0","source":{"id":"2505.18528","kind":"arxiv","version":1}},"canonical_sha256":"b000a795160119fb41eebf2605af0a3377e236b93f47b89c3daf7a23e038324a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b000a795160119fb41eebf2605af0a3377e236b93f47b89c3daf7a23e038324a","first_computed_at":"2026-07-05T11:08:47.741306Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:08:47.741306Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ZTmKmgBUXfedQ12RTrrhieV2Hh2cGi1dd8dNA7zQPixe1mjpW3GnSfcKsOENOx1KBImCJbU6u7DTp0Gs+hJpBw==","signature_status":"signed_v1","signed_at":"2026-07-05T11:08:47.741742Z","signed_message":"canonical_sha256_bytes"},"source_id":"2505.18528","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:568ea87d6ea0680bd96b3bc663f12b658e7c66128e6a044f2b306ceb7715608d","sha256:8c8ec772b26fb62e6c2640449b56bb2aa8e5120a0477131fe221b8da89c01f05"],"state_sha256":"1c92f065a827fd6ea91fca542d431228320cf68d5814d1fc316d7707ceb6830b"}
