Abstract: The present disclosure relates to a gateway device and a method therefor, a medium and an application product. The gateway device includes: a processor; and a memory coupled to the processor and stored with instructions that, when executed by the processor, cause the gateway device to perform the following operations: during connection of the gateway device to an external network via a mobile network: receiving, from a first networked device, a data packet to be forwarded to the second networked device via the gateway device; determining that the data packet has a data volume greater than a threshold data volume; and intercepting the data packet.

Abstract: A technique for providing search results may include determining a first entity type, a second entity type, and a relationship type based on a compositional query. The technique may also include identifying nodes of a knowledge graph corresponding to entity references of the first entity type and entity references of the second entity type. The technique may also include determining from the knowledge graph an attribute value corresponding to the relationship type for each entity reference of the first entity type and for each entity reference of the second entity type. The technique may also include comparing the attribute value of each entity reference of the first entity type with the attribute value of each entity reference of the second entity type. The technique may also include determining one or more resultant entity references from the entity references of the first entity type based on the comparing.

Abstract: A cellulose-silicon oxide composite superhydrophobic material and a preparation method thereof are disclosed. In the method, cellulose substrates with different surface topographies are pretreated by a low-temperature plasma, and then a first silicon oxide layer is deposited on the cellulose substrate by a low-temperature plasma-enhanced chemical vapor deposition method, then modified by a low-temperature plasma, and finally a second silicon oxide layer is deposited thereon, thereby preparing a micro-nano structured superhydrophobic surface on the cellulose substrate, to obtain a cellulose-silicon oxide composite superhydrophobic material, which is an environmentally friendly bio-based hydrophobic material.

Abstract: The present invention relates to the field of single-mode optical fibers and discloses a bending-insensitive, radiation-resistant single-mode optical fiber, sequentially including from inside to outside: a core, inner claddings, and an outer cladding, all made from a quartz material. The inner claddings comprise, from inside to outside, a first fluorine-doped inner cladding and a second fluorine-doped inner cladding. The core and the first fluorine-doped inner cladding are not doped with germanium. The respective concentrations of other metal impurities and phosphorus are less than 0.1 ppm. By mass percent, the core has a fluorine dopant content of 0-0.45% and a chlorine content of 0.01-0.10%; the first fluorine-doped inner cladding has a fluorine concentration of 1.00-1.55%; and the second fluorine-doped inner cladding has a fluorine concentration of 3.03-5.00%.
