Single channel currents through cardiac sarcoplasmic reticulum (SR) Ca2+ release channels were measured in very low levels of current carrier (e.g., 1 mM Ba2+). The hypothesis that surface charge contributes to these anomalously large single channel currents was tested by changing ionic strength and surface charge density. Channel identity and sidedness was(More)
Single cardiac sarcoplasmic reticulum Ca2+ release channels were reconstituted into planar bilayer membranes. Streaming potentials were measured in osmotically asymmetric solutions as a shift in the reversal potential. Potential changes induced by water movement through the bilayer (concentration polarization) and reduced ion activity in the concentrated(More)
In this paper, a two-dimensional Cournot model is proposed to study generation companies' (GENCO's) strategic quantity-setting behaviors in the newly established Yunnan's electricity market. A hybrid pricing mechanism is introduced to Yunnan's electricity market with the aim to stimulate electricity demand. Market equilibrium is obtained by iteratively(More)
