Abstract

fetched live from OpenAlex

Nomenclature A = cross-sectional area of the ribbon Ait� = nondimensional generalized coordinates associated with longitudinal extension Am = maximum cross-sectional area of the ribbon A0 = cross-sectional area of the ribbon at the base ait� = generalized coordinates associated with longitudinal extension Bit� = nondimensional generalized coordinates associated with transverse motion bit� = generalized coordinates associated with transverse motion E = modulus of elasticity of the ribbon material g0 = surface gravity of the Earth � h = characteristic height of the ribbon L = nominally stretched length of the ribbon L0 = nominal length of the ribbon M = number of assumed modes for transverse motion Mc = nondimensional mass of the counterweight (ballast) Mp = nondimensional measure of mass of the tether (ribbon) mc = mass of the counterweight (ballast) mt = mass of the tether (ribbon) mtot = total mass of the system N = number of assumed modes for longitudinal extension RE = radius of the Earth RG = synchronous orbit radius of the Earth s = position on the ribbon t = time U = nondimensional longitudinal extension of the tether along the reference line u = longitudinal extension of the tether along the reference line V = nondimensional transverse motion of the tether relative to the reference line v = transverse motion of the tether relative to the reference line � = angle between the local vertical and reference lines (libration angle) � = ratio of the geosynchronous radius to the radius of the Earth � = bulk density of the ribbon material = nominal strain in the ribbon � = ratio of nominal ribbon length to the radius of the Earth � = gravitational constant of the Earth � = nondimensional position on the ribbon � 0 = nominal stress in the ribbon � = nondimensional time � i = basis functions associated with transverse motion i = basis functions associated with longitudinal extension � = spin rate of the Earth � � = characteristic frequency ratio

Full frame distilled prediction

Teacher imitation

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.
