Abstract: An optical fiber sensing system for temperature and salinity synchronous measurement is provided, which includes a broad-spectrum light source, an optical fiber circulator, a coupler, a first interferometer, a second interferometer, a third interferometer and a spectrometer; the first interferometer is insensitive to temperature and salinity; the second interferometer is sensitive to both temperature and salinity, and the third interferometer is only sensitive to temperature; light emitted by the broad-spectrum light source passes through the optical fiber circulator and enters the first interferometer; reflected light of the first interferometer passes through the optical fiber circulator and the coupler sequentially, and then enters the second and the third interferometers respectively; the reflected light of the second and the third interferometers enters the spectrometer after passing through the coupler; the temperature and the salinity to be measured are simultaneously obtained by performing spectral an

Abstract: A license plate classification method, a license plate classification apparatus and a computer-readable storage medium are provided. The method includes: performing a license plate recognition process on a first license plate image to obtain a license plate recognition result; performing an encoding process on the license plate recognition result to obtain a first license plate feature; performing a feature extraction process on the first license plate image to obtain a second license plate feature; and processing the first license plate feature and the second license plate feature through a classification network to obtain a first license plate classification result. In this way, an accuracy of license plate classification is improved.

Abstract: An underneath type railway freight car bogie wheelset radial device has front and rear subframes and two cross-arranged connecting rods that are pinned by round pin connectors. The subframe is a combination structure of the adapter and the lateral arm. The connecting rods are arranged under the bolster to form the underneath bogie wheelset radial structure. The height of the central plane of the connecting rod is lower than the height of the central plane of the subframe adapter surface. The adapter has an adapter surface forming an arc-shaped adapter structure and an adapter connecting arm integrated with the adapter surface structure and vertically arranged at one end of the adapter surface; the subframes are fixed to the adapter by the rivet assembly.

Abstract: A railway self-generating express freight car bogie has a wheel-axle assembly, frame, journal box suspension device, bolster, foundation brake, side bearing, empty/load auto-adjustment equipment, central suspension device, longitudinal traction device, vertical damper and lateral damper. An axle-end generator is connected at the outer end of an axle of the wheel-axle assembly, the rotor part of the axle-end generator is connected to the end bearing of the wheel-axle assembly by the axle-end bolts, and the stator part is connected to the mount of the journal box suspension devices. The bogie is designed according to the zero-wear concept, and a large number of rubber components and hydraulic dampers are used to improve the lateral stability, linear stability and curve passing performance of the car, so that the bogie is highly adaptable to railway lines, and can meet the operating requirements within 160 km/h and reduce the workload of bogie operation and maintenance.

Abstract: Disclosed is application of emodin in inhibiting amyloid ?-protein (A?) accumulation, improving cognitive and memory abilities, and reducing senile plaques. Alzheimer's disease (AD) is a neurodegenerative disease which is characterized in that nerve cell fibers are entangled. A? plaques are deposited, and a cognitive function is impaired to a pathological feature, and extracellular toxicity accumulation of A? is considered as one of main links of AD pathogenesis. In the present invention, it is discovered that emodin can obviously inhibit accumulation of an A?42 monomer and formation of fibers and inhibit formation of a ? secondary structure, can improve spatial memory learning ability of an AD mouse, and can obviously clear amyloid plaques in APP/PS1 double-transpenic AD model mouse brain tissues. It shows that emodin can be applied to treatment of AD, and research and development of related medicaments.

Abstract: A hierarchical multiscale fibrous scaffold comprises multiple patterned layers of microfibers with one or more layers of nanofibers interleaved therebetween. In a method for making such scaffolds, electrodeposition or near-field electrospinning is used to deposit patterned layers of microfibers in a stack. Conventional electrospinning is used to deposit nanofibers on the layers of microfibers. The method may be used to tune the mechanical properties of the scaffold, facilitated by microfibers, and the biological features of the scaffold, facilitated by nanofibers. Scaffolds produced by such a process may have highly biomimetic architectures, and allow rapid cellular infiltration and sustainable cell growth for multiple tissue types.
