Abstract: Disclosed is a reduced graphene oxide nitrile rubber, comprising the following components in parts by weight: 100-140 parts of nitrile rubber, 30-90 parts of a reduced graphene oxide nitrile rubber masterbatch, 1.8-2.52 parts of a vulcanizing agent, 1.2-1.68 parts of a vulcanization accelerator, 5-7 parts of a vulcanization activator, 17-23.8 parts of a plasticizer, 2-2.8 parts of antioxidant, 59-86.6 parts of a filler, 0.1-0.14 parts of a curing agent, and 2-2.8 parts of dichlorophenol. The reduced graphene oxide nitrile rubber has excellent mechanical properties, a wide applicable temperature range, and strong stability in use, which excellently addresses the poor mechanical properties of the nitrile rubber in the prior art due to high temperature in use and the interfacial compatibility issue between the filler and the rubber.

Abstract: A functionalized graphene oxide nitrile rubber and A tooth-scar-free tooth block is provided. The functionalized graphene oxide nitrile rubber comprises the following components in parts by weight: 100-140 parts of nitrile rubber, 30-90 parts of a functionalized graphene oxide nitrile rubber masterbatch, 1.8-2.52 parts of a vulcanizing agent, 1.2-1.68 parts of a vulcanization accelerator, 5-7 parts of a vulcanization activator, 17-23.8 parts of a plasticizer, 2-2.8 parts of antioxidant, 59-86.6 parts of a filler, 0.1-0.14 parts of a curing agent, and 2-2.8 parts of dichlorophenol. The functionalized graphene oxide nitrile rubber above has excellent mechanical properties, a wide applicable temperature range and strong stability in use, and can be prepared into a tooth-scar-free tooth block.

Abstract: Computer-implemented systems and methods for determining one or more actions to be taken with respect to a first entity. A computer-implemented method can be configured to receive data that is related to characteristics of the first entity as well as data that is related to a plurality of segments. Assignments are determined between the first entity and the segments based upon the characteristics of the first entity and the characteristics associated with the segments. A determined assignment includes a membership probability that is indicative of how probable is membership of the first entity with respect to a segment. One or more actions are determined for the first entity based upon the membership probabilities and action information associated with the assigned segments.

Abstract: This invention discloses a photovoltaic module comprising a photovoltaic module panel and a plurality of photovoltaic module frame segments adapted for holding the photovoltaic module therein; each of the photovoltaic module frame segments comprises a base wall, a photovoltaic module holding part and a first side wall extending between the base wall and the photovoltaic module holding part; the photovoltaic module holding part has a recess facing toward a first direction, the photovoltaic module holding part defines an upper face and a bottom face opposite to each other, wherein said first side wall is oriented at an obtuse angle relative to the bottom face of the photovoltaic module holding part.

Abstract: Computer-implemented systems and methods for analyzing activities associated with accesses of a computer network. A computer-implemented method can be configured to receive data related to the activities associated with the accesses of a computer network. The network activities data are segmented into a plurality of network activities segments. For each of the network activities segments, an anomaly detection predictive model is generated. The generated predictive models are for use in analyzing the activities associated with the computer network.

Abstract: A method and system designed to augment, rather than replace, the work habits of its users. These work habits include practices such as drawing on Post-it™ notes using a symbolic language. The system observes and understands the language used on the Post-it notes and the system assigns meaning simultaneously to objects in both the physical and virtual worlds. Since the data is preserved in physical form, the physical documents serve as a back-up in the case of electronic system failure. With the present invention users can rollout a primary paper document such as a map, register it, and place secondary physical documents on the map. The secondary physical documents can be moved from one place to another on the primary document. Once an object is augmented, users can modify the meaning represented by it, ask questions about that representation, view it in virtual reality, or give directions to it, all with speech and gestures.
