Abstract

fetched live from OpenAlex

Infrared spectroscopy was used to probe the hydration and gelation of curdlan, a linear polysaccharide built from repeating units of (1-->3)-beta-D-glucose. The spectra have been recorded using a temperature-controlled attenuated total reflection (ATR) device. Thermal gelation of curdlan could therefore be followed in situ and in real time. The transformation of the low-set gel, mainly formed with single helices, into a high-set gel, associated with a triple helix structure, could be directly observed. The relative intensities and positions of characteristic absorption bands in the C-O region (1200-850 cm-1) were found to be representative of the gel structure, as they are believed to be sensitive to the helical conformation of the polymer chains. Infrared (IR) spectroscopy is shown to be a useful tool for rapid and efficient characterization of curdlan gels.

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.
