Abstract

fetched live from OpenAlex

Suturing simulations, of which real-time knotting and unknotting are the most challenge parts, are essential to today's surgical training systems. In this paper, we present a physics-based approach to real-time simulation of deformable linear objects (DLOs) with visual and force feedback. In our suture model, which can represent the mechanical properties of a real thread such as stretching, compressing, bending, and twisting, we simulate not only external forces, but also internal forces including the friction force during knotting and unknotting. We also present how forces propagate along the suture when the user pulls it with one or two hands. We developed a simulator to allow users to grasp and smoothly manipulate a virtual thread, and to tie an arbitrary knot.

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.
