Arbitrarily Shapeable Couplant with Fluidity Onset for Conformal Ultrasound
Bibliographic record
Abstract
Couplant is indispensable for ultrasound examinations. However, shape adaptability and operational feasibility, which are both crucial, cannot be provided conjointly by existing couplants due to their either liquid or solid form. Here an ideal couplant composed of fibers and dynamically cross-linked polysilicone is reported, which exhibits a unique solid-to-fluid transition upon application of stress exceeding a threshold. Together with the acoustically transparent feature, the particularity of the stress-triggered fluidity allows conformal adapting to arbitrary geometries under stress exertion and stable preserving for long-term and reliable ultrasound examination after stress release. Steeply curved geometries and pressure-sensitive tissues, which are extremely challenging for the state-of-the-art ultrasound modalities, are successfully graphed or treated. This couplant integrates the merits of liquids and solids, providing new opportunities for various ultrasound in industrial and medical fields.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
