A coarse timing synchronization acquisition method in a mobile communication system is applied to the timing synchronization acquisition of a mobile communication system that transmits the same signal blocks repeatedly, which comprises: starting from the beginning time instant of timing synchronization acquisition, iteratively calculating the delay correlation accumulation (DCA) values at K samples, when K is the number of DCA values at each time slot; M time slots are searched in each frame, the position corresponding to the maximum DCA value is taken as the estimate of timing synchronization position; M timing synchronization position estimates are obtained, and among these, one timing synchronization position estimate is selected as the candidate for the current frame timing synchronization position, and it is decided whether the candidate is reliable; after L frames are searched, a predicted timing synchronization position of the next frame is obtained by using the L timing synchronization positions.

Droplets or plugs within multiphase microfluidic systems have rapidly gained interest as a way to manipulate samples and chemical reactions on the femtoliter to microliter scale. Chemical analysis of the plugs remains a challenge. It has been discovered that nanoliter plugs of sample separated by air or oil can be analyzed by electrospray ionization mass spectrometry when pumped directly into a fused silica nanospray emitter nozzle. Using leu-enkephalin in methanol and 1% acetic acid in water (50:50 v:v) as a model sample, we found carry-over between plugs was

At least a first capacitor is formed on a substrate and connected to a first differential node of a differential circuit, and the first capacitor may be variable in capacitance. A second capacitor is formed on the substrate and connected to a second differential node of the differential circuit, and the second capacitor also may be variable. A third capacitor is connected between the first differential node and the second differential node, and is formed at least partially above the first capacitor. In this way, a size of the first capacitor and/or the second capacitor may be reduced on the substrate, and capacitances of the first and/or second capacitor(s) may be adjusted in response to a variable characteristic of one or more circuit components of the differential circuit.
