Abstract: A method for preparing a supercapacitor with good cycling stability uses NiO@CoMoO4/NF, an activated carbon plate, a KOH solution (6 mol/L), and polypropylene as raw materials, and is implemented through preparation of an NiO@CoMoO4/NF electrode and assembly of the supercapacitor, wherein the NiO@CoMoO4/NF is the anode of the supercapacitor, the activated carbon plate is the cathode of the supercapacitor, the KOH solution is the electrolyte, and the polypropylene is an isolation plate. The NiO@CoMoO4/NF electrode in the supercapacitor of the present disclosure treated with the ductile material can better adapt to volume changes during the charging and discharging process. After 10,000 cycles of charging and discharging, the capacity of the present disclosure has not faded and still maintains 100% of the maximum capacity, with a high specific capacitance of 79.4 F/g, an energy density of 35.7 Wh/kg, and a functional density of 899.5 W/kg.

Abstract: A switching power amplifier includes logic circuitry that generates first and second components of a differential signal, based on received amplitude code and a delayed version of the same. The amplitude code includes a sign and a magnitude. When the sign is positive, a first logic path is configured to generate the first component based on the received amplitude code and the second logic path is configured to generate the second component based on the delayed amplitude code. When the sign is negative, the first logic path is configured to generate the first component based on the delayed amplitude code and the second logic path is configured to generate the second component based on the received amplitude code. The switching power amplifier further includes a differential-to-single ended conversion circuit configured to generate a single-ended signal based on the differential signal.

Abstract: Methods, systems and programming for personalized presentation of content are presented. In one example, a first reference to a first content item is provided to a user. An input is received from the user indicating that the user is following the first reference to access the first content item. A likelihood is calculated, where the likelihood represents how likely the user will be interested in an additional content item similar to the first content item. An actionable representation of the additional content item is provided to the user. The actionable representation comprises an additional reference to the additional content item. The actionable representation is presented in a manner determined based on the calculated likelihood.
