A method to optimize calls to a service by components of an application running on an application server is provided. The method includes providing a handle substrate having a surface region. The active converter has a triac adjusting the DC voltage, and switching elements of the inverter perform self-oscillation under control of the phase of the resonance current flowing through the resonance circuit. 0\xd710\u221216 Am2particle to about 3. The electrodes or energy delivery elements are configured for direct andor indirect application of thermal andor electrical energy to heat or otherwise electrically modulate neural fibers that contribute to renal function.
