Abstract: Techniques and architecture are described grouping various sources of traffic within a network into grouping fields and assigning each combination of grouping field values an aggregate identification (ID). A first hop edge router may receive a packet and search a mapping table for a corresponding aggregate ID for the combination of grouping field values within the mapping table. If not found, the first hop edge router may assign a corresponding aggregate ID for the combination of grouping field values and store the new aggregate ID for the combination of grouping field values in the mapping table. The first hop edge router may forward the packet on through the network with the aggregate ID embedded in metadata. Routers within the network may measure and aggregate flow metrics of the packet within the network based on the aggregate ID and provide the measurements to the network controller.

Abstract: The present invention offers some general specifications for the design, assembly, and adaptation of a rotating cylinder electrochemical cell into an autoclave, of a high temperature and pressure system for corrosion studies that simulate operating conditions in pipelines, as well as the operation and safety of an autoclave to evaluate the electrochemical process of metal surfaces exposed to aggressive aqueous solutions. The electrochemical cell consists of an array of three electrodes that include a rotating cylinder electrode designed to operate hermetically, a reference electrode and an auxiliary electrode. The rotating cylinder electrode is considered to be the working electrode, where the oxidation and electrochemical reduction processes are studied. However, the use of the method described in this work can be extended to other testing environments and materials by taking into account the physical and chemical properties of the fluids and materials to be used in order to avoid any risk for the operator.

Abstract: An application of a hydrogel in the preparation of products for the treatment of bacterial infection is disclosed. Ferrous ion was used in the antibacterial activity test of Staphylococcus aureus and showed a strong bactericidal effect, which the survival rate of Staphylococcus aureus is less than 0.001%, as well as the survival rate of methicillin-resistant Staphylococcus aureus (MRSA) was less than 0.01%.

Abstract: An IoT service of a provider network may be used to optimize downlink scheduling for edge devices that use a radio communication protocol (e.g., LoRaWAN). A processing instance receives DL packets from a client application that are to be sent to an edge device. The processing instance adds metadata entries (device ID, message ID) to a metadata queue and stores the DL packets into a data store. A scheduling instance obtains a metadata entry and the associated DL packet, formats the DL packet based on edge device information, and publishes the packet to a gateway topic. A separate connection instance receives the formatted DL packet and sends it to a gateway of the client network.
