Abstract

fetched live from OpenAlex

The Deficit Below Threshold method was applied to characterize low flows in terms of volume, duration and intensity for 31 hydrometric stations in New Brunswick, Canada. The volume, duration and intensity data series were fitted to seven distributions which are the Pareto (PAR), gamma (GAM), Weibull (WEI), log-logistic (LLOG), log-normal (LN), Kappa (KAP) and exponential (EXP) distributions. The goodness of fit was assessed using the Anderson-Darling statistic. For volume, the KAP, LN, LLOG, PAR and WEI distributions gave the best fit. LN, LOG and KAP distributions were best fitted to the duration while the WEI, GAM, LLOG and the LN distributions provide the best fit for intensity. The skew coefficients (Cs) were also calculated for the data series for V, D and I and can provide insight to which distributions may be adequate to fit the low flow characteristics.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
