Abstract
The outer core region of Helicobacter pylori lipopolysaccharide of the majority of isolates contains an alpha-1,6-glucan polymer synthesized by the product of the HP0159 ORF. Structural studies carried out on HP0159 lipopolysaccharide mutants by a combination of chemical methods, mass spectrometry and nuclear magnetic resonance spectroscopy confirmed that insertional inactivation of HP0159 gene in H. pylori strains 26695 and SS1 resulted in formation of a truncated lipopolysaccharide molecule characterized by the presence of a terminal dd-heptose residue in the side-chain outer core fragment and maintaining an inner core backbone structure compared with the wild-type Lewis antigen-expressing strains. Colonization studies with HP0159 mutants of two mouse-colonizing strains, SS1 and M6, confirmed their inability to successfully colonize the murine stomach.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
