- Preindustrial labor-material ratio was 5:95 to 10:90 (materials far more expensive than labor)finding0.759Historical baseline showing that fine-tuning presented no special problem when labor was cheap relative to materials.
- Modern labor-material ratios of 50:50, 60:40, and 70:30 are now common in building constructionfinding0.736Quantitative finding establishing why labor-intensive traditional techniques are no longer economically viable.
- The ratio of total building floor area to site area, used to characterize density.
- Role specialization where fitness effects of particle characters reverse depending on context (e.g., germ/soma); formal game-theoretic equivalent to non-linearly separable functions.
- Primary evaluation metric measuring causal effect of interventions; greater value indicates larger causal effect
- A state of balance among forces, creating an appearance of stasis; can be symmetrical or dynamic.
- The capacity of a few instructed cells to recruit neighbors to complete a morphogenetic task, observed in ectopic eye induction.
- Prior-work method for selecting the optimal layer for truth probing by maximizing class separability.
