The emission current was set to 4.2 μA and data collection was in 2 GHz mode, mass range m/z 50-650. For all GC/QTOF-MS experiments, the sample injection order was randomized using the “RAND” function in Microsoft Excel. The same GC column was used for data acquisition shown in ...

mode component source 12 is coupled between one input terminal and ground 20. Impedances 62 and 64 are selected to establish the gain of amplifier 60. Specifically, from well known formulae, which are valid for differential amplifiers having a high open loop gain, the output voltage of an ...
A. Differential Mode For differential mode, we set S1 = −S2 = 1V , S3 = 0, and assume Cp = Cs = Cm = 0 for simplicity. The input impedance at Port 1 and 2 can be found as 1 ω2M2 Zin1,dif f = Zin2,dif f = 2 (Zp + Z3 ) + Zs (33) and the power gain (or ...
finding local maximum and minimum points on thegraph, as well as changes in inflection (convex to concave, or vice versa). When examining a function used in amathematical model, such geometric notions have physical interpretations that allow a scientist or engineer to quickly gain a feeling for...

Next, one has to approximate the Fourier coefficients (see (107)) γ j ( σ ) , j = 0 , ⋯ , s − 1 , needed in (108): for this purpose, we consider the Gauss-Legendre quadrature formula of order 2 k . In order to gain full machine accuracy, when using the double precisi...
