Abstract: A segmented grouting method for ramp drivage in an aquifer is provided. Concerning grouting reinforcement for a ramp in an aquifer, a grouting process is divided into four stages according to a pressure change, that is, micro-pressure filling, low-pressure diffusion, medium-pressure reinforcement, and high-pressure fracturing. In the micro-pressure filling, an initial pressure of a grouting orifice is 0, and a low-concentration single-component grout is used to fill an original fissure of the aquifer. In the low-pressure diffusion, a low-concentration bicomponent grout is used for grouting, the original fissure is expanded, and a grouting radius is increased. In the medium-pressure reinforcement, a high-concentration bicomponent grout is used for grouting, thereby reinforcing the aquifer. In the high-pressure fracturing, a high-concentration bicomponent grout is used to reinforce a new fractured fissure of the orifice caused by a high pressure and the original fissure, thereby forming a confining bed.

Abstract: An audio data transmission method. An electronic device transmits audio data to a first earbud of a TWS headset by using a first CIS of a first CIG, and transmits audio data to a second earbud of the TWS headset by using a second CIS of the first CIG. The electronic device determines that the TWS headset is switched from a double-earbud mode (namely, a mode in which the first earbud and the second earbud are used together as audio input/output devices of the electronic device) to a first single-earbud mode (namely, a mode in which the first earbud is independently used as an audio input/output device of the electronic device). In response to the determining, the electronic device deactivates the second CIS, stops transmitting audio data to the second earbud by using the second CIS, and continues transmitting audio data to the first earbud by using the first CIS.

Abstract: Described herein are methods and systems useful in the fabrication of ultrasound transducer devices. Fabrication of ultrasound transducer devices can comprise manipulation of components having extremely small cross-sectional thicknesses, which can increase the risk of damage to the components. For example, inadvertent application of forces sufficient to damage such components is a significant risk during fabrication steps. As described herein, the risk of damage to an ultrasound transducer device component having a small cross-sectional thickness, such as an ultrasound microelectromechanical system (MEMS) wafer, can be reduced by partially or completely coating or filling all or a portion of the component with a stabilizing material, for example, prior to subjecting the component to forces associated with manipulation of the component during the fabrication process.

Abstract: Provided are a system switching method and apparatus, an electronic device, and a non-transitory computer-readable storage medium. When a second operating system is run by the electronic device, a first Bluetooth service is supported independently by the second operating system. When a first operating system is run by the electronic device, the first operating system is required to indirectly communicate with a Bluetooth module by means of the second operating system. When the first operating system is run by the electronic device, the first Bluetooth service is supported by the first operating system and the second operating system. Therefore, when the electronic device is switched from running the second operating system to running the first operating system in response to a first instruction, a second processor running the second operating system is always in a communication connection with the Bluetooth module without a communication interruption.

Abstract: In a method for content stream processing, a coded content stream of a content stream is received from a server. Second trigger timing information of the coded content stream is obtained. The second trigger timing information is determined based on first trigger timing information of the content stream and stream time change information. The stream time change information indicates a timing change between the coded content stream and the content stream. The first trigger timing information indicates a target event in the content stream. The coded content stream is decoded. The decoded content stream is played back. When the decoded content stream is played to the target event indicated by the second trigger timing information, specified processing corresponding to the target event is performed.

Abstract: A double-stranded DNA biomarker derived from exosomes is useful in early diagnosis and preoperative evaluation of pheochromocytoma and paraganglioma, and applications thereof. The biomarker is genome double-stranded DNA fragment specifically derived from exosomes in blood serum of pheochromocytoma and paraganglioma patients. The double-stranded DNA can represent variations of RET, VHL, and HIF2A with high frequency of somatic cell mutation, and metastatic phenotype-related SDHB, which are susceptibility genes of PCCs and PGLs. The circulating exosome DNA in patient's peripheral blood contains 97% of the same chromosomal point mutation information as the tumor cells from which the DNA originated. There is evidence of the existence of double-stranded DNA in the serum exosomes of PCCs and PGLs. The double-stranded DNA can be used to identify mutations in tumor cells and provide a noninvasive molecular marker for the clinical diagnosis and preoperative evaluation of PCCs and PGLs.
