Abstract: A GNSS emergency monitoring error suppression method for an alpine canyon complex environment is provided. Through three steps of GNSS optimization design of the alpine canyon complex environment, derived error suppression of emergency monitoring criteria in the alpine canyon complex environment, and error suppression measurement and result correction, GNSS measurement errors in the alpine canyons can be effectively suppressed. Through improving measurement accuracy, GNSS technology can be widely applied to the alpine canyons, outstanding advantages of high efficiency and high accuracy in a coordinate transmission process of the GNSS technology are brought into full play, and a cost is effectively reduced. Meanwhile, by processing the errors of the emergency monitoring criteria, it is possible to protect workers from on-site operation risks.

Abstract: A train having a protection device with self-adaptive crashworthiness is disclosed, which relates to the technical field of safety protection of trains. The train includes multiple vehicles, a head vehicle is located at the head end of the train, and a head vehicle energy absorbing coupler mechanism is mounted at the front end of the head vehicle, each two adjacent vehicles are connected to each other by a middle vehicle energy absorbing coupler mechanism. An image acquisition mechanism and a radar detector are mounted at the head vehicle for monitoring whether there is an obstacle ahead the train, measuring distance and collision speed between the train and the obstacle, and for transmitting measured data to a processing center of the train, the processing center optimizes and adjusts impact force at the head vehicle energy absorbing coupler mechanism and the middle vehicle energy absorbing coupler mechanisms based on a collision situation.

Abstract: An R—Fe—B based magnet having gradient electric resistance and a method for producing the same are provided. The magnet includes an exterior layer (G) and a main body layer (H). The exterior layer (G) is connected with the main body layer (H) via a sintered layer (I). The oxygen content in the exterior layer (G) is higher than the oxygen content in the main body layer (H), so the electrical resistivity of the exterior layer (G) is not lower than the electrical resistivity of the main body layer (H). The R—Fe—B based magnet having gradient electric resistance is capable of maintaining high resistance and excellent magnetic performance simultaneously.

Abstract: Europium-containing fluorescent nanoparticles and methods of preparing such nanoparticles are provided. The nanoparticles are comprised of an aluminum oxide framework having a europium activator, a magnesium, calcium, strontium, or barium energy reservoir, and at least one co-activator selected from the group consisting of scandium, yttrium, and certain lanthanide elements. The nanoparticles may be optionally coated with a silane coating containing reactive functional groups that allow for attachment of the nanoparticle to a desired biological or chemical target molecule. The coated nanoparticles may be used to detect a variety of protein ligand interactions, and may also be used in assays for nucleic acids.
