In this study, we explore how motility-dependent chemical deposition and concentration-sensitive feedback can give rise to fractal-like networks, using a minimal agent-based model. Agents deposit chemicals only while moving, and their future motion is biased by local chemical gradients. This interaction generates a rich variety of self-organized structures resembling those seen in processes like early vasculogenesis and epithe","authors_text":"Abhishek Chaudhuri, Debasish Chaudhuri, Subhashree Subhrasmita Khuntia","cross_cats":["cond-mat.soft","cond-mat.stat-mech"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.bio-ph","submitted_at":"2025-04-23T09:09:29Z","title":"Self-organized fractal architectures driven by motility-dependent chemotactic feedback"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2504.16539","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":"sha256:28512a11fdc2b6fa2e92d2e46f3a99d7dc7400adc390156f8f503961acaab057","target":"record","created_at":"2026-07-05T10:53:01Z","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":"dd689848f06c0f7677ebf62894496a204a40ab0effd89f9b985f4630db13e10b","cross_cats_sorted":["cond-mat.soft","cond-mat.stat-mech"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.bio-ph","submitted_at":"2025-04-23T09:09:29Z","title_canon_sha256":"15e7a26207d1dc679efe3705b594bb5dc24efcb6b11b9c4cdc5398df839b3844"},"schema_version":"1.0","source":{"id":"2504.16539","kind":"arxiv","version":1}},"canonical_sha256":"cf03dc7460f0fbc94ad945c65d213e0ebe6e5a540d7b60a813d29dd84998d8da","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cf03dc7460f0fbc94ad945c65d213e0ebe6e5a540d7b60a813d29dd84998d8da","first_computed_at":"2026-07-05T10:53:01.280427Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:53:01.280427Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"8bDZHm6UTt19g+EIB1qQ314K00g/Ei8aFOAe4SdY1iQ3m+24Zs9aT12o3tR5/iu85ZTsWQaTYfUAqH5bFr6NDw==","signature_status":"signed_v1","signed_at":"2026-07-05T10:53:01.280839Z","signed_message":"canonical_sha256_bytes"},"source_id":"2504.16539","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:28512a11fdc2b6fa2e92d2e46f3a99d7dc7400adc390156f8f503961acaab057","sha256:5fa4eb831dd38a3f35b87f69bb66bb48f25fa94a3b1a463755d5d879e0aeec45"],"state_sha256":"1c2239df61ff35742c023b0ac17ff81c3ba5df28e89410f74d4b7413cfde4695"}
