The authors fit these models to 3,325 virtual blood pressure and flow waveforms and report better fits than the classical models, along with a new parameter they propose as a viscoelasticity biomarker.","discovery_kind":"extension","skeptic_critique":null,"referee_report":null,"author_rebuttal":null,"desk_editor":null,"rs_alignment":null,"lean_confirmation":null,"pith_extraction":null,"created_at":"2026-08-14T15:58:09.584122+00:00","model_set":{"reader":"deepseek-v4-flash"},"falsifier":null,"supporting_citations":[],"review_version":1}
