Abstract: The present invention provides anti-HBV compounds, pharmaceutically acceptable compounds or stereoisomers thereof, and preparation methods and uses for treating, eradicating or inhibiting HBV infection or for alleviating liver injury caused by HBV infection, and so on.

Abstract: A system for managing objects is provided. The system comprises a data collection gateway and a plurality of apparatus. Each of the plurality of apparatus obtains parameters relating to objects in a farm from a server through the data collection gateway. The parameters include a reference threshold weight of the objects. Each of the plurality of apparatus collects weights of the objects through sensors. Also, each of the plurality of apparatus adjusts the reference threshold weight based on the obtained parameters to generate an adjusted threshold weight. Further, each of the plurality of apparatus sorts the objects to different areas in the farm based on the adjusted threshold weight and the collected weights.

Abstract: A camera module and a terminal device are disclosed. The camera module includes a support mechanism, a filter and a sensor disposed corresponding to the filter, where the support mechanism includes substrates, support frames and buffers, the support frames each are disposed on the substrate, an edge of the filter is fixed on the support frame, and the butlers each are disposed between the substrate and the support frame. In this way, even if a suspended area of the filter increases relative to the sensor and shaking moment of the filter acting on the support frame increases, the support frame does not shake significantly relative to the substrate, and can keep its own stability under effective support by the buffer, which significantly reduces a probability of collision between the support frame and the filter, thereby ensuring assembly stability and integrity of the filter when the suspended area increases.

Abstract: The invention relates to a gas distribution panel for a fuel cell wherein gas guiding channels having a meandering-shaped structure and which extend in a parallel manner are arranged. The invention is characterized in that cell connectors having various widths are provided on the meander-shaped defining channels in order to reduce transversal transportation of media along the meander-shaped defining channels. The invention also relates to a fuel cell provided with a gas distribution channel arranged on the cathode side and/or anode side, especially a polymer-electrolyte membrane (PEM) fuel cell.
