Abstract: This application provides a Bluetooth communication method and an electronic device. The method includes: A first operating system in a first device may establish a first Bluetooth connection between the first device and a second device by using an HCI channel and a second operating system. This provides a possibility for the first operating system of the first device to perform Bluetooth communication with the second device, and helps a container of the first device to communicate with the second device.

Abstract: A testing system for measuring loss of soil particles with different particle sizes in a water inrush process includes: a vibration screening apparatus; a water collecting apparatus for collecting the mass of water and transmitting the water to a collecting and calculating apparatus; a conveying apparatus for conveying screened soil particles to a weighing apparatus; a weighing apparatus used for weighing the screened soil particles and transmitting the measured weight of the screened soil particles to the collecting and calculating apparatus; and a collecting and calculating apparatus used for controlling the operation of the testing system, inputting parameters and calculating data. The condition of particle loss in a simulated tunnel water inrush process can be automatically measured in real time, providing a basis for researching the influence caused by the particle sizes of fillings in the water inrush process of the tunnel to water inrush.

Abstract: A dimming switch system (130). The system (130) may include a dimming switch (520), a weak current module (510) and a strong current module (530). The weak current module (510) may receive at least one drive signal and control a state of the dimming switch (520) based on the drive signal. The strong current module (530) may be connected to the dimming switch (520) and at least one lighting device (140). The strong current module (530) may control brightness of the lighting device (140) connected thereto based on the state of the dimming switch (520). The dimming switch (520) may include a phase-cutting switch (610) and at least one omnidirectional conduction unit (620). When the omnidirectional conduction unit (620) works, the dimming switch (520) is omnidirectionally conductive.

Abstract: A medical adhesive with good biodegradable performance capable of undergoing crosslinking copolymerization, comprising a mono-alpha-cyanoacrylate and a bis-alpha-cyanoacrylic acid diol ester monomer molecule. The olefinic bonds in the mono-alpha-cyanoacrylate structure are polymerized in the presence of infinitesimal anions to form a solid 3D high polymer; the 3D high polymer is provided with degradation sites on the web-like backbone chain, with clear degradation path and absorbable degradation products. The medical adhesive can be used for wound adhesive, large area wound hemostasia, and visceral and soft tissue wound closure.

Abstract: A pegylated artesunate derivative, a pharmaceutical composition and uses thereof, the pegylated artesunate derivative is represented by the general formula (I): The pegylated artesunate derivative has activity comparable to that of artesunate, increased water solubility and stability, and an extended half-life in vivo.

Abstract: Disclosed are an injectable sustained-release pharmaceutical formulation and a process for preparing the same. In some embodiments, the formulation comprises an active ingredient in a therapeutically effective amount, an amphipathic molecule, an organic acid and/or a salt thereof which is hardly soluble in water, and an oily solvent. The injectable sustained-release pharmaceutical formulation provides a good sustained-release effect for various active ingredients, in particular peptides, proteins, nucleic acids and saccharides.
