Abstract

fetched live from OpenAlex

Whole-plant corn untreated (Control) or treated with an inoculant ( Lentilactobacillus buchneri, Lentilactobacillus hilgardii, and Pediococcus pentosaceus, INO) was ensiled for 210 days in mini-silos at constant (MS-C) or variable temperature (MS-V) or for 220 days in bunkers. Bunker samples were collected at 50 (D50) and 150 (D150) cm below silo surface. Samples from MS-V and MS-C had similar pH and concentrations of lactic acid, propionic acid, 1,2-propanediol, and ethanol, but different acetic acid content ( P = 0.009). Additionally, MS-V exhibited greater bacterial ( P = 0.002) and fungal ( P = 0.011) richness than MS-C. Inoculation decreased ( P < 0.001) lactic acid levels while increasing ( P < 0.05) acetic acid, 1,2-propanediol, and fungal richness in both mini-silos and bunker. In bunkers, samples collected from D50 had a lower aerobic stability ( P < 0.05) than D150, but inoculation increased ( P < 0.05) aerobic stability compared to Control, regardless of sampling depth. The storage temperature of mini-silos did not markedly impact the fermentation profile or fungal community. Overall, inoculation increased acetic acid production and fungal diversity in mini-silos, regardless of the storage temperature, and in bunkers, irrespective of sampling the depth, improving the aerobic stability of D50 and D150 bunker silages after long-term ensiling.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
