Fully discharging phases. A new approach to biphasic waveforms for external defibrillation.
BACKGROUND Phase-2 voltage and maximum pulse width are dependent on phase-1 pulse characteristics in a single-capacitor biphasic waveform. The use of 2 separate output capacitors avoids these limitations and may allow waveforms with lower defibrillation thresholds. A previous report also suggested that the optimal tilt may be >70%. This study was designed to determine an optimal biphasic wavefo...
متن کاملDischarging cartwheels
In [J. Combin. Theory Ser. B 70 (1997), 2-44] we gave a simplified proof of the Four Color Theorem. The proof is computer-assisted in the sense that for two lemmas in the article we did not give proofs, and instead asserted that we have verified those statements using a computer. Here we give additional details for one of those lemmas, and we include the original computer programs and data as “...
متن کاملMinimal counterexamples and discharging method
Recently, the author found that there is a common mistake in some papers by using minimal counterexample and discharging method. We first discuss how the mistake is generated, and give a method to fix the mistake. As an illustration, we consider total coloring of planar or toroidal graphs, and show that: if G is a planar or toroidal graph with maximum degree at most κ − 1, where κ ≥ 11, then th...
