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

Abstract The crystal structure of aprocitentan Form A has been solved and refined using synchrotron X-ray powder diffraction data and optimized using density functional theory techniques. Aprocitentan Form A crystallizes in space group P-1 (#2) with a = 11.7381(11), b = 10.6771(12), c = 9.6624(5) Å, α = 110.4365(13), β = 92.3143(13), γ = 113.513 (2)°, V = 1,017.53(5) Å 3 , and Z = 2 at 298 K. The crystal structure consists of layers of aprocitentan molecules, approximately along the 1,-7,7 plane. N–H···N hydrogen bonds link the molecules within these layers. The powder pattern has been submitted to the International Centre for Diffraction Data for inclusion in the Powder Diffraction File™.

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.
