We compute linear and quadratic static density response functions of three-dimensional Yukawa liquids by applying an external perturbation potential in molecular dynamics simulations. The response functions are also obtained from the equilibrium fluctuations (static structure factors) in the system via the fluctuation-dissipation theorems. The good agreement of the quadratic response functions,...

The sum rule formalism is used to evaluate rigorous bounds for the density and current static response functions in superfluid He at zero temperature. Both lower and upper bounds are considered. The bounds are expressed in terms of ground state properties (density and current correlation functions) and of the interatomic potential. The results for the density static response significantly impro...

Cold-sensitive nerve terminals (CSNTs) encode steady temperatures with regular, rhythmic temperature-dependent firing patterns that range from irregular tonic firing to regular bursting (static response). During abrupt temperature changes, CSNTs show a dynamic response, transiently increasing their firing frequency as temperature decreases and silencing when the temperature increases (dynamic r...

In this study, we tested the hypothesis that nitric oxide (NO) production in the dorsal horn is involved in producing the pressor reflex elicited by static contraction of skeletal muscle. Cats were anesthetized with alpha-chloralose (80 mg/kg) and urethane (100 mg/kg), and a laminectomy was performed. With the exception of the L7 dorsal root, the dorsal and ventral roots from L5 to S2 were sect...
