Abstract

fetched live from OpenAlex

We have used a relatively new microscopical technique, environmental scanning electron microscopy (ESEM), along with transmission electron microscopy (TEM) and light microscopy, to investigate a unique microbial community from a temperate-climate, cold sulfide spring near Ancaster, Ontario, Canada. ESEM allows the viewing of fully hydrated specimens that have not undergone the structural or chemical alterations imposed by the extensive procedures necessary for viewing biological specimens in a vacuum. Besides allowing visualization of microorganisms in their natural form and as intact assemblages, ESEM also detects elements, especially those lighter than Si, which tend to be lost or masked by the processes used to prepare samples for conventional SEM and for TEM thin sections. In this study we report new information about the structure of bacteriogenic sulfur deposits and their relationship to the structural aspects of a natural microbial community from a cold sulfide spring.

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.
