Abstract: Devices for controlling to remove food waste digestion foam are provided. The device includes a digestion tank. The digestion tank includes two hermetically sealed boxes. Each of the two boxes is opened with a liquid inlet connected to an interior of each of the two boxes. A conveying mechanism is connected between the two boxes. The conveying mechanism conveys a gas in the two boxes in a reciprocal manner. The gas in the two boxes is conveyed in the reciprocal manner through the conveying mechanism to generate a pressure difference between the two boxes distributed left and right to remove the foam, which adopts physical defoaming without adding any reagent, is cost-effective and efficient, and does not affect an anaerobic reaction process due to addition of a chemical defoaming agent. The entire device has a simple structure and is easy to operate, and the process is controllable.

Abstract: The disclosed data transmission circuit and a memory include a sense amplifier circuit, a first sub-discharge path, a second sub-discharge path, and a discharge adjustment unit. The sense amplifier circuit generate amplified signals based on two terminals. The first sub-discharge path, in the read state, discharges at the first terminal to the discharge terminal based on the first data line signal; the second sub-discharge path, in reading state, discharges at the second terminal to the discharge terminal based on the discharge adjustment signa. The discharge adjustment unit is electrically connected to the second sub-discharge path and the control signal, but is not connected to the first sub-discharge path, and is used for generating the discharge adjustment signal based on the control signal, to adjust the discharge capacity of the second sub-discharge path. The present disclosure improves the anti-interference ability and data transmission efficiency of the data transmission circuit.

Abstract: Techniques for cancer patient management, and more particularly, to techniques for ultrasensitive detection of circulating nucleic acid with prior knowledge of variants to be monitored in the blood. An exemplary technique includes detecting one or more variants in a sample of cell free DNA from a subject. The one or more variants are selected from a plurality of variants known to be specific to a tumor or disease area of the subject. The technique further includes counting the detected one or more variants, determining a tumor burden based on the count of the one or more variants, and determining a statistical significance of the tumor burden based on whether the detection of the one or more variants is associate with true signals or background noise.
