Abstract

fetched live from OpenAlex

Surface stabilized bilayer lipid membranes (s-BLMs) made from egg phosphatidylcholine on silver wires have been used as transducers to electrochemically detect hybridization of short DNA oligomers. The ion currents through s-BLMs were used to monitor hybridization of 20 mer and 25 mer oligonucleotides. Single stranded DNA oligonucleotides that were modified by attachment of a 16 carbon aliphatic chain were immobilized onto the lipid membranes. Various quantities of complementary and partially complementary sequences (each without the aliphatic chain), were introduced as titrants to observe the degree of interaction with the immobilized DNA. The results indicated that hybridization could be detected for mixed base sequences, and for partially complementary sequences. Quantitative results are dependent on the degree of surface occupancy by DNA, on the degree of complementarity of sequences, and on the base sequence within the oligonucleotides.

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.
