Project nGene.org® is a research-oriented educational software workbench developed by Hyunsuk Frank Roh, MD. It brings together hemodynamic modeling, waveform analysis, anatomy visualization, respiratory-mechanics education, ECG simulation, signal-processing demonstrations, and structured medical computation. HEMODYNAMIC MODELING AND READER'S NOTES • Logistic-Based Systolic Model for pulmonary artery pressure estimation and systolic waveform simulation • Mechanics of Blood Circulation - Reader's Notes: an equation-centered guide covering Chapters 1–8, with independently developed diagrams, explicit assumptions, chapter-specific simulations, and an integrated systemic-pulmonary circulation laboratory • The Fluid Mechanics of Aortic Stenosis — Reader's Notes: a study aid for Colin Clark's paired 1976 papers, with source separation, uncertainty statements, and a reader-developed native simulation Reader's notes and simulations are presented separately from the original publications. They are educational interpretations and are not validated patient-specific cardiovascular models. ECHO REFERENCE • Search by disease, equation, measurement, threshold, or source • Organized pathways for equations, chambers, rhythm/conduction/pacing, diastolic function, heart failure and advanced therapies, native and prosthetic valves, valvular hemodynamics, right heart and pulmonary hypertension, cardiomyopathy and pericardium, stress echocardiography, shunts, and aortic disease • Focused tables that keep criteria, interpretation, cautions, and source anchors together • Source sheets, citations, lookup guidance, and available publication links Echo Reference is a quick-reference and source-navigation aid. It does not replace the original guidelines or papers, independent accuracy verification, or formal echocardiographic interpretation. OTHER INCLUDED RESOURCES • Medical equation tools • eGFR and CKD/ESRD reference tables • Ventilation-specific equation tools • Independent Component Analysis waveform demonstration • Chest vascularity visualization • MDRO research dataset viewer • Optional Virtual Ventilator Test-Lung educational add-on • Optional Virtual EKG Simulator educational add-on • Optional Echocardiography Recognition educational preview • Optional IV Nutrition Therapy formulation helper The ICA heart-sound examples are based on the UMich Heart Sound & Murmur Library. Lung-sound examples are based on HLS-CMDS: Heart and Lung Sounds Dataset Recorded from a Clinical Manikin using Digital Stethoscope, Version 3, DOI: 10.17632/8972jxbpmp.3. Attribution and license information are provided in the app. This software is intended for research-oriented education, model inspection, anatomy learning, waveform visualization, signal-processing education, respiratory-mechanics education, ECG simulation education, and structured medical-reasoning education. It is not presented as a diagnostic, monitoring, or treatment device. It does not provide patient-specific clinical decisions and must not replace clinician judgment, ventilator management, respiratory therapy protocols, ECG interpretation, cardiac-rhythm diagnosis, auscultation diagnosis, formal echocardiographic interpretation, prescription decisions, reimbursement decisions, or clinical claim submission. On iOS, the display name appears as “Project_nGene.org” and represents Project nGene.org®.
