A single acidic residue can guide binding site selection but does not govern QacR cationic-drug affinity. [PDF]
PLoS ONE, 2011 Structures of the multidrug-binding repressor protein QacR with monovalent and bivalent cationic drugs revealed that the carboxylate side-chains of E90 and E120 were proximal to the positively charged nitrogens of the ligands ethidium, malachite green ...

Direct Measurement of Fast Transients by Using Boot-strapped Waveform Averaging [PDF]
, 2017 An approximation to coherent sampling, also known as boot-strapped waveform averaging, is presented. The method uses digital cavities to determine the condition for coherent sampling. It can be used to increase the effective sampling rate of a repetitive
