Prior results from both experiments and simulations report that the shear stress $\\sigma$ scales with strain rate $\\dot \\gamma$ as $\\sigma \\sim \\dot \\gamma^{1-\\Delta}$, with values of the exponent ranging between $2/3 <\\Delta \\le 1$. However it remains unclear what properties of the system select the value of $\\Delta$, and in particular under what conditions the system displays a yield stress ($\\Delta = 1$). To address these questions, we perform simulations of a minimalistic model system in whi"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1706.06378","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
