While any number of social, psychological, and economic factors contribute to methamphetamine (MA) addiction risk, numerous biological variables have also been identified [...]

This investigation applies non-stationary time-series analysis methods and the St.Venant equations to model tidal range, tidal species amplitudes, and phases of water sur [...]
