Abstract: An epidermal biosensor comprising a diffusion layer operable to dissolve a solid-phase epidermal analyte, an enzymatic bioreceptor operable to oxidise the dissolved epidermal analyte from the diffusion layer, a transducer having an interface with the diffusion layer, a processor configured to process electrochemical data from the transducer, and a substrate to which the enzymatic bioreceptor and the transducer are attached. The solid-phase epidermal analyte may include water-insoluble cholesterol and water-soluble lactate. The diffusion-solvation layer may comprise agarose hydrogel and additives including glycerol and/or gelatin to improve mechanical robustness and reduce water evaporation rate of the hydrogel, and ethanol and/or Triton X-100 to facilitate solvation and transportation of hydrophobic analytes.

Abstract: A scanning apparatus (110), a medical image obtaining method, and a medical image obtaining system (100) are provided. The scanning apparatus (110) comprises a gantry, a controller, a C-shaped arm, a radiation source (112), and a detector (113). The radiation source (112) and the detector (113) are arranged at both ends of the C-shaped arm. The C-shaped arm is connected to the gantry. The controller is configured to control a motion of the gantry to drive the C-shaped arm to move so as to scan a target object.

Abstract: Embodiments of the disclosure provide a live-streaming starting method, apparatus, device, storage medium, program product and program. The server receives a live-streaming starting request initiated by a terminal for streaming media; determines a starting segment according to a predetermined delay threshold, the starting segment comprising a media presentation description MPD file, an initialization segment, and a media segment corresponding to the delay threshold; and the terminal receives the starting segment sent by the server, and renders and plays a first frame of the streaming media using the starting segment. On the basis of a DASH protocol, the solution improves a live-streaming starting process, to enable a terminal to render and play a first frame only by initiating a starting request once, thereby effectively reducing a starting time and improving the user experience.

Abstract: Some embodiments of the disclosure provide accounting methods for carbon footprints of leather products. In some examples, the accounting method includes the following steps: firstly, determining a system boundary for a carbon footprint in a life cycle of a leather product; dividing the carbon footprint into a raw material production and transportation stage, a leather product production stage, and a leather product transportation and distribution stage within the system boundary for the leather product; determining carbon emission source inventories of the stages and emission factors thereof in combination with process and flow characteristics of the stages, and then constructing carbon emission accounting models of the stages, and calculating carbon footprint data of the stages, and, finally, obtaining the carbon footprint of the leather product.

Abstract: Provided are a PCIe interrupt processing method and apparatus, a device and a non-transitory readable storage medium, relating to the technical field of computers. The PCIe interrupt processing method comprises: a currently generated internal interrupt signal is acquired; a PCIe interrupt type supported by a current FPGA is determined according to an interrupt vector signal output by a PCIe IP core, so as to determine a corresponding target interrupt processing mechanism according to the PCIe interrupt type; and the internal interrupt signal is processed by means of the target interrupt processing mechanism, and a processing result is input to the PCIe IP core, such that the PCIe IP core sends an interrupt message packet to a central processing unit on the basis of the processing result. The technical solution expands the compatibility of an FPGA with processor interrupts, facilitating the implementation of FPGA logic platform construction.
