Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for switching a secondary cell to a primary cell. A user equipment (UE) monitors a first radio condition of the UE for beams of a primary cell and a second radio condition for beams of one or more secondary cells configured for the UE in carrier aggregation. The UE transmits a request to configure a candidate beam of at least one candidate secondary cell as a new primary cell in response to the first radio condition not satisfying a first threshold and the second radio condition for the at least one candidate secondary cell satisfying a second threshold. A base station determines to reconfigure at least one secondary cell as the new primary cell. The base station and the UE perform a handover of the UE to the new primary cell.

Abstract: A water cooling head with sparse and dense fins, including a main body, a first fin set and a second fin set. Wherein a chamber is formed inside the main body, the main body has a first plate and a second plate, the main body forms an inlet channel and an outlet channel, so that the cooling water passes through the chamber. The first fin set and the second fin set are arranged in the chamber, and the first fin set and the second fin set are connected to the first plate respectively. The first fin set comprises several first fins spaced apart, the first fins divide the chamber to form several first channels. The second fin set comprises several second fins spaced apart, the second fins divide the chamber to form several second channels. The water cooling head can increase the overall heat sinking efficiency.

Abstract: An electronic device, a carrying buckle, and a carrying frame of a carrying buckle are provided. The carrying frame is integrally formed as a single one-piece structure and is insertable into a retaining case along an insertion direction for being fixed in the retaining case. The carrying frame includes a body segment, two buckling arms respectively extending from two opposite sides of the body segment, and an elastic structure that extends from the body segment. The elastic structure is elastically deformable when being pressed along the insertion direction, such that an abutting end of each of the two buckling arms has a displacement that allows the abutting end to be abutted against the retaining case.

Abstract: For methane activation, various sulfonation systems using SO3 or H2SO4 have been well studied, however, sulfur dioxide (SO2), a preliminary source of SO3 and H2SO4, has not been used successfully. Herein, we report a novel methane sulfonation method to produce methanesulfonic acid (MSA) utilizing sulfur dioxide by a free radical mechanism. In the presence of H2O2 as a radical initiator, the reaction of SO2 and O2 in trifluoroacetic acid (TFAOH) furnished trifluoroacetylsulfuric acid (TFAOSO3H), which served as the radical propagator to facilitate H-abstraction of methane at low temperatures. In typical reactions, sulfur dioxide was incorporated into MSA in 75% with high selectivity at 60° C.

Abstract: A magnetic body includes a plurality of laminated inner layers and an insulating enclosure fully enclosing the inner layers therein. The inner layers include a first or central metal layer, each one of upper and lower sides of which is sequentially provided with a first insulating layer, a second metal layer, a filter layer, a second insulating layer, a third metal layer, and a light-absorbing material layer. Each of the metal layers is negatively charged and formed by coating a specific high-temperature vaporized metal element on an entire surface of an insulating body. The filter layer is woven from an insulating material and has at least 144 millions of meshes per square inch. The light-absorbing material layer stores pre-absorbed light energy. The magnetic body with the above-described structure produces a radial magnetic field of force that provides enhanced magnetizing effect.

Abstract: A purifier with molecular-rearranging device mainly includes a hollow tubular holder, a tubular molecular-rearranging device positioned in the tubular holder, a tubular isolating layer positioned in a bore of the tubular molecular-rearranging device, and two caps respectively having a through hole closed to two ends of the tubular holder. The purifier may be put around an exhaust pipe or a pipe for transferring liquid, so that a radiated magnetic field is produced by magnetic lines of the molecular-rearranging device and earth poles to magnetize and rearrange molecules of exhaust or liquid flown through the pipe, making the exhaust or liquid filtered and purified to reduce air and water pollution.

Abstract: A magnetic body includes a disc-shaped carrier having one or more layers of magnetic powder that is blended with a viscous liquid and sprayed on outer surfaces of the carrier. Magnetic lines of the magnetic body together with earth poles produce a radiated magnetic field. When the magnetic body is positioned in a vehicle fuel tank cap, the radiated magnetic field produced by the magnetic body causes magnetization and rearrangement of fuel surface molecules and/or air molecules in the limited space in the fuel tank to enable effective fuel volatilization and accordingly upgraded kinetic energy efficiency of a vehicle engine.
