... with low concentration of spin labels should be detected. At low concentration of spin labels where high receiver gain is required to obtain a spectrum of good quality, it is difficult to follow ... that at low microwave power the variance of the EPR signal would be minimum over the whole field scan at the out-of-phase setting, the correct phase angle can be calculated from two high -power spectra ... nucleotide reported disorder. The low- angle X-ray diffraction patterns were modified by AdoPP[CH 2 ]P in insect flight muscle; the ratio of the two inner equatorial peaks was lowered when the concentration...

... SOLUTIONS 9 4.11 D = N(GH) 1/N + P. Compare in a spreadsheet. Design (b) is fastest for H = 1 or 5. Design (d) is fastest for H = 20 because it has a lower logical effort and more stages to drive the ... of the internal nodes is guaranteed to be high rather than low. Thus 11 + 2.5 = 13.5 units of capcitance are high and 5 units are low, reducing the charge sharing noise to 13.5 / (13.5 + 5) ... 40960. The best number of stages is log 4 F = 7.66, so try an 8-stage design: NAND3-INV-NAND2- INV-NAND2-INV-INV-INV. This design has an actual logical effort of G = (5/3) * (4/3) * (4/3) = 2.96,...
