In contrast to a V-shaped wedge or U-shaped microchannel, it is argued that droplet coarsening takes place by viscous hydrodynamic transport through a stable column of liquid that coexists with the droplets in the groove at a slightly positive Laplace pressure. With some simplifying assumptions, this leads to a t^(1/7) growth law for the characteristic droplet size as a function o","authors_text":"Patrick B Warren","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2015-01-21T16:34:14Z","title":"Beading instability and spreading kinetics in grooves with convex curved sides"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1501.05220","kind":"arxiv","version":2},"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":"sha256:18b8ea396e352186abd0f209f07979087b7b9c31fb6359945a8ac8c4e9aaa572","target":"record","created_at":"2026-05-18T01:23:38Z","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":"6682af441818d1e2cf84bce80837d5d22a0de822c3afe54f45c42deeb2b18d58","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2015-01-21T16:34:14Z","title_canon_sha256":"9392d937aac1ef2d1634d0ace191c70d382fd0b1491bcb230a0a73f752ce5446"},"schema_version":"1.0","source":{"id":"1501.05220","kind":"arxiv","version":2}},"canonical_sha256":"ea2db4b4da333a54360d2b4e1cfdd8881ae2201e0db767b1e9b7b953d8d06758","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ea2db4b4da333a54360d2b4e1cfdd8881ae2201e0db767b1e9b7b953d8d06758","first_computed_at":"2026-05-18T01:23:38.551355Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:23:38.551355Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"q8T5tkmIHgfyJhQlQCkhYWCFxF1B+FKeGyCX0L4XRgIZB77ShWOLov8fzyKJMXWPpxk183TwfJcXzKq6w0XUBw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:23:38.552050Z","signed_message":"canonical_sha256_bytes"},"source_id":"1501.05220","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:18b8ea396e352186abd0f209f07979087b7b9c31fb6359945a8ac8c4e9aaa572","sha256:116c409478f80027bbe9dd6eae860d4f3e85a6dd65b91258a85d1d52770e0a07"],"state_sha256":"53bedd67e4d094ac9bdac2d643bde125d5785619d99a743157dc7f5750f10b87"}
