Dose-Response & Pharmacokinetics

Primes about how a system's response scales with an input dose: threshold, tolerance, and receptor saturation mark regime boundaries, half-life and bioaccumulation track a substance's persistence, and inverted-U response and therapeutic window locate the safe range between too little and too much.

14 primes in this family — primes that sit near one another in abstraction space (k-means over structural-signature embeddings). Each is shown with its short description.

• Bioaccumulation — Progressive concentration.
• Dose-Response Relationship — Input-output mapping.
• Half-Life — Time to halve quantity.
• Hysteresis — Path dependence.
• Inverted-U Response — A response variable rises with a driver, peaks at an interior optimum, then falls — a single-peaked non-monotone relationship in which the same lever that helps below the peak reverses sign and harms above it.
• Linearity — Proportional output.
• Nonlinearity — Disproportionate output.
• PK/PD Modeling (Pharmacokinetics / Pharmacodynamics) — Predict dynamic system behavior.
• Potentiation — One factor enhances another.
• Ratio — Compare one quantity with a nonzero reference quantity by division, so the quotient states how much numerator obtains per unit of denominator and stays interpretable only while both quantities, their units, and their scope are named.
• Receptor Saturation — Plateau effects at capacity.
• Therapeutic Window — Optimal input range.
• Threshold — Safe vs harmful levels.
• Tolerance — Reduced effect with repetition.
