Abstract: Techniques associated with bezel-antenna sharing for a foldable device are described. To enhance a user experience with foldable devices and overcome unique challenges associated with wireless communication in foldable devices having two operating modes (e.g., closed mode and open mode), the techniques described herein integrate near-field communication (NFC) functionality with antenna detune elements, located on a bezel of a flip side of the foldable device, in a way that enables the NFC and radio frequency (RF) antennas to operate in both the closed and open modes. Integrating NFC with the bezel also reduces the overall thickness of the foldable device compared to conventional devices that use an NFC coil. In aspects, multiple detune elements on the bezel are bridged together to increase a length of an antenna used for NFC functions, without impacting performance of actively driven antennas (e.g., cellular, WiFi) on an opposing side of the foldable device.

Abstract: The present disclosure relates to the technical field of molecular diagnosis, and particularly, to a microsphere formulation for nucleic acid amplification, an amplification method, and use in joint detection. The disclosed microsphere formulation can be stored for a long duration at 2-8° C. When the microsphere preparation is used, no solvent is additionally added, and the microsphere formulation is directly mixed with a sample to be detected. On the premise that the concentration of an original system is not changed, the template content in the system can be remarkably improved, so that the detection sensitivity is improved. By using the microsphere formulation in recombinase polymerase amplification (RPA), recombinase-aided amplification (RAA), or a double or multiple detection formed by combining a second reaction on the basis of RPA or RAA, the sensitivity can be remarkably improved, and meanwhile, the amplification specificity is ensured.
