In a timescale of ~100 ps, there are ~10% more possibilities for the particle moving along the initial orientation than moving opposite to the orientation; and the diffusion distances of the particle reach ~1 nm. We find that the key to this observation is the orientation-dependence of the damping force to the moving of the nanoscale particle and a finite time is required to regu","authors_text":"Haiping Fang, Nan Sheng, Pan Guo, Rongzheng Wan, Yusong Tu","cross_cats":["physics.bio-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2013-07-26T09:07:08Z","title":"Asymmetrical free diffusion with orientation-dependence of molecules in finite timescales"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1307.6963","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:f35d4b0bc522c3aeffd31b233726a5a83b6394c7e7180dfdeff1dc3a6c74d0a5","target":"record","created_at":"2026-05-18T03:17:25Z","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":"f4c6a4ae909cca211ce4b0096205076ee879849e4cbb87c3dcfdac81bb6b129c","cross_cats_sorted":["physics.bio-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.soft","submitted_at":"2013-07-26T09:07:08Z","title_canon_sha256":"43b652a7e7f1983e1c73c1bc1ecd5a5f2dc2ea8d97717cef05447b544d499bf2"},"schema_version":"1.0","source":{"id":"1307.6963","kind":"arxiv","version":1}},"canonical_sha256":"0bd322e040bdba2503d769bb17bd87799d5d1e776ab4b5440bb1528b7b5a0887","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0bd322e040bdba2503d769bb17bd87799d5d1e776ab4b5440bb1528b7b5a0887","first_computed_at":"2026-05-18T03:17:25.701880Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:17:25.701880Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"VhZTy0wjx528UJbVfQBif0C3KdH0uQBk71n6WNsctbKrb/Ek+GigOq3zKsbV6KjJTz4DODHfSWL8QQ8o34cQDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:17:25.702558Z","signed_message":"canonical_sha256_bytes"},"source_id":"1307.6963","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f35d4b0bc522c3aeffd31b233726a5a83b6394c7e7180dfdeff1dc3a6c74d0a5","sha256:4c4fe8e1ca4f7a5712e234b1768f79693949f1efe6282c3b7dc466ab24670e65"],"state_sha256":"661d5416f9a8a28766e0440ab09c66b850cd56e36fa8ca6d15b2dd841dc997fa"}
