Abstract

fetched live from OpenAlex

Abstract A gelatin nanofiber film that shows a failure tensile stress of 35 MPa, much stronger than conventional polyacrylamide hydrogels (<0.2 MPa), tough double network hydrogels (0.2–1.0 MPa), some engineering plastics such as polyethylene films (16 MPa) and polysulfones (1–10 MPa), is prepared by electrospinning. It is processed into a graphene oxide film, which exhibits high conductivity, via a high‐temperature treatment. A simple approach to prepare graphene oxide films using gelatin is provided. A highly sensitive and responsive wearable sensor is fabricated using the graphene oxide film, which is capable of sound recognition, apexcardiogram recording, and pulse spectrum measurement. The apexcardiogram is strongly associated with hemodynamic cardiac health, which reflects the cardiac process of ventricular contraction, blood ejection, diastole, semilunar valve open/close, atrioventricular valve valve open/close, etc. The developed cardiac sensor could be used to measure arterial stiffness index, a derivative of pulse spectrum, useful to evaluate artery walls stiffness and health status. Using the developed sensor, the detection result can be wirelessly relayed to mobile devices for personal cardiac health monitoring.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
