Abstract: A display panel, a motherboard, and a mini LED display device. The display panel includes: a panel edge extending along a first direction, and a display region and a test region. The test region is between the display region and the panel edge and includes test pads. At least two test pads are arranged along the first direction, adjacent ones of which are spaced by at least two first electrostatic discharge protection wires extending from one side of the display region adjacent to the test region to the panel edge. Each first electrostatic discharge protection wire includes a first line segment located between two adjacent test pads and a second line segment adjacent to the panel edge. A distance between adjacent first line segments between two adjacent test pads in the first direction is less than a distance between adjacent second line segments in the first direction.

Abstract: A remote-sensing yield estimation method is described that is applicable to a crop whole growth period and belongs to the field of data processing methods and photogrammetry technologies with prediction purpose. In the present disclosure, in combination with agricultural knowledge of crop yields and multi-source remote-sensing data, with the biomass estimation model of whole growth period, the biomass contribution rate curve and the crop harvest index as basis, a crop yield estimation model of whole growth period with stable spatiotemporal extensibility is constructed. The yield estimation model uses the relative accumulated temperature and the remote-sensing vegetation index as variable inputs. Further, based on genetic algorithm, the parameters of the model are optimized in a case of failing to directly construct the model with data fitting due to less sample points, so as to help solve the problems of poor spatiotemporal mobility of the yield estimation model.

Abstract: A method for extracting pullulan polysaccharide from high-viscosity fermentation broth includes following steps: (1) removing cells from the fermentation broth; (2) removing proteins; (3) decolorizing by macroporous resin adsorption; (4) removing ions by ultrafiltration; and (5) drying, crushing and packaging. In the extraction method of the present application, by using natural polymer bioflocculant chitosan, the high-viscosity fermentation broth can be processed without dilution and addition of filter aids and organic solvents for alcohol precipitation, which reduces the pressure of subsequent decolorization, properly recycles the cell proteins, and avoids the potential hazard of the organic solvents. The method can obtain high-purity pullulan polysaccharide, improving the product yield and quality, reducing solid waste, reducing the production cost, and achieving a safe, efficient, continuous and automated production process.

Abstract: An Address Resolution Protocol (ARP) packet processing method. a communication system and a device are disclosed. The method includes: receiving an ARP packet, and judging the type of the ARP packet; when the ARP packet is an ARP request, responding to the ARP request if an entry corresponding to the ARP request is found in a local ARP table; and when the ARP packet is an ARP response. reporting the ARP response if an entry corresponding to the ARP response is found in the local ARP table and a reporting parameter in the entry indicates permission of reporting; or discarding the ARP response if no entry corresponding to the ARP response is found in the ARP table.

Abstract: A method and an apparatus for defending against Address Resolution Protocol (ARP) spoofing attacks are disclosed. When a network device receives an ARP message, the network judges whether the MAC address of the received ARP message is the same as the MAC address in an ARP entry, if the MAC addresses are different, the network device determines the received ARP message as an ambiguous ARP message and starts an ARP verification process, and makes further process according to the result of the ARP verification process. In this way, when no address spoofing attacks occur, no verification messages are generated, and thus reducing signaling interactions and saving network resources; besides, spoofing attacks possibly happening at any time are avoided, which effectively prevents address spoofing attacks via random scanning and protects the normal application of the real host.

Abstract: A method and an apparatus for defending against Address Resolution Protocol (ARP) spoofing attacks are disclosed. The method includes: when an ARP entry is updatable, judging whether the MAC address of a received ARP message is the same as the MAC address in the ARP entry, where the ARP message has the same Internet Protocol (IP) address as the ARP entry; if the MAC addresses are different, determining the received ARP message as an ambiguous ARP message and starting an ARP verification process, or else starting no ARP verification. In this way, when no address spoofing attacks occur, no verification messages are generated, and thus reducing signaling interactions and saving network resources; besides, spooling attacks possibly happening at any time are avoided, which effectively prevents address spoofing attacks via random scanning and protects the normal application of the real host.
