Abstract

fetched live from OpenAlex

Abstract Oligonucleotide probes have been used to detect bacteria and archaea that colonize the cattle and pig digestive system. The Fluorescent in situ hybridization (FISH) is a molecular biology technique that uses oligonucleotides of 15 to 25 nucleotides of length associated with a fluorescent molecule. In microbiology, the FISH technique utilizes probes targeting ribosomal RNA (rRNA). It is one amongst others, a staining technique that allows the identification, detection and quantification of microorganisms without prior cultivation by means of epifluorescence and confocal laser scanning microscopy (CLSM). In this study, we describe the usage of the confocal laser scanning microscopy coupled with fluorescence in situ hybridization (FISH), in order to detect and quantify of bacteria and archaea in fecal samples from cattles’ manure and swine slurry.

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.
