Abstract: One example method includes performing, in a global environment that includes a central node and edge nodes that are able to communicate with each other, by the central node, operations including: sampling optimal information from the edge nodes concerning a state of the global environment, based on the optimal information, updating a global map of the global environment, based on the optimal information, updating an information retrieval cost, using the state of the global environment to orchestrate placement and execution of one or more tasks and actions in the global environment, using the updated global map, information retrieval cost, tasks and actions to update an attention mechanism operable to control retrieval of next optimal information, and selecting next optimal information for retrieval.

Abstract: Thermoplastic elastomer, which comprises a fumed, hydrophilic or hydrophobic silica, which has been structurally modified and also a process for the improvement of the mechanical properties of thermoplastic elastomers. The thermoplastic elastomers are produced by preparing a masterbatch from the components (e.g. thermoplastic resin component and fumed silica) and compounding this with further thermoplastic elastomers.

Abstract: A heat transfer liquid in the form of a molten salt mixture includes a mixture of potassium nitrate and lithium nitrate, and added calcium nitrate and/or anhydrous salts if appropriate. This is done in order to achieve a low melting point, a low toxicity and in particular a low viscosity. The heat transfer liquid may be used in the vulcanization of rubber.
