Groundwater Well Drawdown (Theis)
Confined-aquifer Theis solution: cone of depression s(r,t) = (Q/(4πT)) W(u), u = r²S/(4Tt); transmissivity, storativity, observation well.
Dose-Response & Hill Curves
Pharmacologic Hill E(C): EC50/IC50, Hill slope nH, agonist vs antagonist shifts, and therapeutic-window sketch (ED50 vs TD50).
Cable Equation on an Axon
1D passive cable ∂V/∂t = D∂²V/∂x² − (V−V_r)/τ + I; compare uniform fiber vs myelinated (higher D in internodes).
SIRS with Waning Immunity
SIRS compartments with waning ωR→S, booster pulses, seasonal β(t), endemic equilibrium, and R0 vs fade-out.
SIR Vaccination Threshold
Herd-immunity threshold simulator: R_eff = R0(1-v), SIR outbreak curves, peak infected, and final size vs vaccine coverage.
