Data and code for "The sense and control of standing balance in the presence of motor noise"
Bibliographic record
Abstract
These files contain the MATLAB code and data required to reproduce Figures 2–4 and Supplementary material of “The sense and control of standing balance in the presence of motor noise”. The Data folder contains .mat files with all trials of participants from Experiment 1, 2, and 3 separately. Data include measured whole-body angle, forces and moments, together with derived measures such as angular velocity, d′, thresholds, and power. The supplementary material contains descriptions of the Linear Quadratic Regulator (LQR) model simulations together with for the supplementary figures (S1-2). The LQR model represents balance control as an inverted pendulum stabilized by optimal state feedback with a Smith predictor to compensate for sensory and motor delays, and includes nonlinear elements such as ankle stiffness, signal-dependent motor noise, and muscle activation dynamics. The MATLAB code of the LQR model is also provided and further details on the implementation can be found at https://github.com/AminMNasr/NonlinearityLQR.git.
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 machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
