The supply voltage Vout decreases as a load current of the power supply increases. Vmin?Vout?V, where Vmin is a lowest supply voltage of the processor at the operating frequency in the next time period, and V is a specified supply voltage of the processor at the operating frequency in the next time period.

Abstract: An ultra-sensitive digital rapid chromatographic assay system includes a chromatography system, an optical imaging system, and an image processing system. The chromatography system is a lateral flow or vertical flow chromatography system. The detection area on a reaction membrane of the chromatography system is immobilized with capture biological ligands, the analytes to be detected is specifically enriched by means of the captured biological ligands, and the analytes enriched in the detection area is specifically recognized by the detection biological ligands labelled with tracer nanoparticles. The optical imaging system can visualize a single tracer nanoparticle specifically bound on the reaction membrane. The image processing system includes a detection area recognition module and a nanoparticle counting module, and the counted number of tracer nanoparticles specifically binding to the detection area and the concentration of the analytes to be detected are a proportional relationship.

Abstract: This application provides a memory training method, a memory controller, a processor, and an electronic device. The memory controller keeps transmission delays of N DQs unchanged, adjusts a transmission delay of a DQS, and determines a maximum DQS transmission delay and/or a minimum DQS transmission delay of the DQS when all data carried in the N DQs is correctly transmitted. The memory controller adjusts the transmission delay of the DQS to a target DQS transmission delay between the maximum DQS transmission delay and the minimum DQS transmission delay. The method helps quickly align relative timing positions between the DQS and the N DQs. Therefore, memory training may be repeatedly performed in a working process of the processor, so that the N DQs keep enough timing margins.

Abstract: A nanobowl-supported drug-loaded liposome, a preparation method therefor, and an application thereof. The preparation method for the nanobowl-supported drug-loaded liposome comprises: incubating and ultrasonically treating a nanobowl and a liposome and then successfully encapsulating a drug by utilizing an ammonium sulfate active drug loading method to obtain the nanobowl-supported drug-loaded liposome. The nanobowl-supported drug-loaded liposome can resist the influence of plasma proteins and blood flow shearing forces on drug leakage, enhance the delivery of the drug at a tumor site, improve carrier stability, and improve an anti-tumor curative effect.

Abstract: This application provides a load line circuit and an electronic device, where the load line circuit is applied to the electronic device. A voltage value of a feedback voltage provided by the load line circuit to a switch-mode power supply is linearly and positively correlated with each of a voltage value of a first voltage and a current value of a first current, where the first voltage is a voltage provided to a load circuit, and the first current is a current provided to the load circuit. Through disposition of the load line circuit, the switch-mode power supply can implement a load line function.
