Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

aboutThe title or abstract carries a Canadian signal from the geographic lexicon.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

Eine große Zahl von mechanischen Kreislaufunterstützungssystemen wurde in den vergangenen 30 Jahren entwickelt. Bei den Systemen, die zur Überbrückung bis zur Herztransplantation („bridge to transplantation“) oder als Überbrückung bis zur Erholung des Myokards („bridge to recovery“) zum Einsatz kommen, konnten die größten klinischen Erfolge mit den implantierbaren pulsatilen Pumpensystemen erzielt werden. Das Novacor® LVAS (N100 Left Ventricular Assist System, World Heart Inc., Ottawa, Kanada), ein reines Linksherzunterstützungssystem, wurde von Peer M. Portner in Oakland/CA, USA entwickelt und konnte erstmals im Jahre 1984 am Stanford University Hospital bei einer Patientin mit terminaler Herzinsuffizienz erfolgreich implantiert werden (9, 10). Die implantierbare Pumpeneinheit blieb bis heute unverändert, während die Antriebs-und Steuerungseinheit ständig verkleinert wurden und die Patienten dadurch zu Hause leben können (3).

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.
