متن کاملIntermediate Values and Inverse Functions on Non-archimedean Fields
Continuity or even differentiability of a function on a closed interval of a non-Archimedean field are not sufficient for the function to assume all the intermediate values, a maximum, a minimum, or a unique primitive function on the interval. These problems are due to the total disconnectedness of the field in the order topology. In this paper, we show that differentiability (in the topologica...
متن کاملDelta-Sigma Modulators using Frequency- Modulated Intermediate Values
This paper describes a new firstand second-order delta-sigma modulator concept where the first integrator is extracted and implemented by a frequency modulator with the modulating signal as the input. The result is a simple delta-sigma modulator with no need for digital-to-analog converters, allowing straight-forward multi-bit quantization. Without the frequency modulator, the circuit becomes a...

متن کاملSignificance of Intermediate Values of Fractional Flow Reserve in Patients With Coronary Artery Disease.
BACKGROUND The fractional flow reserve (FFR) value of 0.75 has been validated against ischemic testing, whereas the FFR value of 0.80 has been widely accepted to guide clinical decision making. However, revascularization when FFR is 0.76 to 0.80, within the so-called gray zone, is still debatable. METHODS AND RESULTS From February 1997 to June 2013, all patients with single-segment disease an...
