In both simulations and experiments we find that the wall-induced convection occurs inside the bouncing bed region of the parameter space in which the granular bed behaves like a bouncing ball. A good agreement between experiments and simulations is found for the peak vibration acceleration at which convection starts. By comparing the results of simulations initialised with and without defects, we find that the onset of convection occu","authors_text":"Andrea Fortini, Kai Huang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2014-10-06T09:07:24Z","title":"Role of defects in the onset of wall-induced granular convection"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1410.1291","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":"sha256:21822f24ad9c122870896cee5bc15d08568dfa09f16ace247f715ba12e25ac58","target":"record","created_at":"2026-05-18T01:41:52Z","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":"3f7d0c0f947782da3153dd05bbf4bafec8fbcdf71bd58481a19af492992c7c8a","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2014-10-06T09:07:24Z","title_canon_sha256":"f471758d5aea8872547e1eefc62750770cd48ef6592ac3018c1c67e26565e312"},"schema_version":"1.0","source":{"id":"1410.1291","kind":"arxiv","version":2}},"canonical_sha256":"87416c6108bbd6701aff4fa5f476aef35db82f785547b53ca5788a9f79f010c8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"87416c6108bbd6701aff4fa5f476aef35db82f785547b53ca5788a9f79f010c8","first_computed_at":"2026-05-18T01:41:52.355380Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:41:52.355380Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QzMZVYN6dgyFoUnwe0Jdz9fEPISwDSpenc5DFOqZ1+u47A6dulO+/nOSU33SajNIrctA83pS8tjupsr2lLQDCw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:41:52.356024Z","signed_message":"canonical_sha256_bytes"},"source_id":"1410.1291","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:21822f24ad9c122870896cee5bc15d08568dfa09f16ace247f715ba12e25ac58","sha256:78a213b1bd4999e91a854afe448c15e74a04d9e6851d16bc5695de1f5c0a22be"],"state_sha256":"d019946100f2a1f4cbb15b3df9f49bbec8a0fbff0b1e1fa7e3d19ef12e433668"}
