Abstract

fetched live from OpenAlex

Abstract Under the low-stress cropping working condition, a pre-stress notching technology is proposed. According to the force and deformation features of the bar, a cutting force model of notching is established to divide the cutting area into three parts and analyze the mechanism of splitting and friction respectively. The pre-stress notching experiment platform is built to conduct the comparison test between the cutting force of notching under the pre-stressed state and the free state. The experimental results show that the reasonable pre-stress state reduces the shear part and the friction part by 25.4% and 47.8% respectively, which can effectively improve the cropping efficiency and prolong the durability of the cutting tool.

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. 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.
