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

Objective To study the correlation between CT perfusion imaging of acute cerebral infarction and vascular cognitive impairment(VCI).Methods Sixty-nine patients with acute ischemic cerebral infarction(onset within one week) underwent CT perfusion scanning.Their VCI was detected by Montreal cognitive assessment(MoCA) after 3 weeks.The patients were divided into VCI group with a MoCA score 26(n = 40) and control group with a MoCA score≥26(n = 29). The general data,cerebral blood volume(CBV) and cerebral blood flow(CBF)in the affected side were compared with those in the non-affected side.Results The dependent daily living ability and the ratio of cerebral infarction at the left side and temporal lobe were higher in VCI group than in control group.The CBV and CBF were lower in the affected side than in the non-affected side of both groups.The CBV and CBF in the lesion side were significantly lower in VCI group than in control group(P0.05).The MoCA score was negatively correlated with the local CBV and CBF (r=-0.3758,-0.4772,P0.01).Conclusion Decreased cerebral blood perfusion is correlated with VCI in patients with acute cerebral infarction.

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.
