    摘要： A system may include a processor and a memory. The memory may include program code that provides operations when executed by the processor. The operations may include: partitioning, based at least on a resource constraint of a platform, a global machine learning model into a plurality of local machine learning models; transforming training data to at least conform to the resource constraint of the platform; and training the global machine learning model by at least processing, at the platform, the transformed training data with a first of the plurality of local machine learning models.

    摘要： A charge-domain IMC circuit is disclosed and includes: a cluster of 6T SRAM cells; a charge- domain MAC circuit; and an LBL connected to a bit-line of each of the 6T SRAM cells. The MAC circuit includes: a MOS transistor; an input switch; an output switch; an input port; an output port; and a capacitor. The LBL is connected to a gate of the MOS transistor. A first terminal of the MOS transistor is connected to a DC voltage, and a second terminal of the MOS transistor is connected to the output port via the output switch. The second terminal of the MOS transistor is connected to the input port via the input switch and to a first side of the capacitor. A second side of the capacitor is grounded. Other variants of the IMC circuit are disclosed, some of which having a ciSAR ADC or a TD-ADC.

    摘要： A simple immunosensor for rapid and high sensitivity measurements of protein biomarkers, such as SARS-CoV-2 nucleocapsid protein, in serum. The assay is based on a unique sensing scheme utilizing dually labeled magnetic nanobeads for immunomagnetic enrichment and signal amplification. This immunosensor can be integrated onto a microfluidic chip, which offers the advantages of minimal sample and reagent consumption, simplified sample handling, and enhanced detection sensitivity.
    An ultrafast magneto-immunosensor, which employs AC electrothermally driven flow (ACEF) for accelerated mass transport and enhanced immunocomplex formation, is developed for high sensitivity protein measurement in whole blood samples.
