Abstract: A combined cable includes a row of cables having a plurality of cables separated from each other in a width direction of the combined cable, each of the cables extending in a length direction of the combined cable, a first film disposed on a side of the row of cables, and a second film disposed on another side of the row of cables opposite the first film in a thickness direction of the combined cable perpendicular to the width direction and the length direction. The first film and the second film are bonded to each of the cables. A portion of each of the first film and the second film between adjacent cables of the row of cables is not bonded together.

Abstract: A cable includes at least two insulated core wires, an insulation structure, a first shielding layer, a second shielding layer, and a second insulation layer. Each insulated core wire includes a conductive wire core and a first insulation layer wrapped over the conductive wire core. The insulation structure is wrapped around an outside of the at least two insulated core wires and fixedly positions the at least two insulated core wires therein. The second insulation layer is circumferentially wrapped around an outside of both the first shielding layer and the second shielding layer. Each of the first shielding layer and the second shielding layer circumferentially surrounds a portion of an outer circumferential surface of the insulation structure and together form a combined shielding layer circumferentially wrapped over the entire outer circumferential surface of the insulation structure.

Abstract: A cable includes at least two conductive wire cores spaced apart from each other and extending in a longitudinal direction of the cable, and an interior insulation structure circumferentially wrapped around and contacting each of the at least two conductive wire cores to fix the at least two conductive wire cores. The interior insulation structure is a foamed insulation structure in which the at least two conductive wire cores are fixedly maintained. The cable further includes an internal insulation layer wrapped over and contacting the interior insulation structure on an outer side of the interior insulation structure, a first conductive shielding layer wrapped over the internal insulation layer on an outer side of the internal insulation layer, and an external insulation layer wrapped over an outside of the first conductive shielding layer.

Abstract: A polyfluoroalkoxy resin and a method of preparing the same. The method includes: S1: charging deionized water, an organic solvent, a surfactant, and a chain transfer agent to a polymerization kettle; S2: after heating to a set temperature ranging from 50° C. to 80° C., charging an appropriate amount of polymerization monomer consisting of tetrafluoroethylene and perfluoroalkyl vinyl ether till reaching a set pressure ranging from 0.7 MPa to 1.5 MPa, followed by charging an initiator to start reaction; S3: adding additional polymerization monomer and perfluoroalkyl vinyl ether polymerization promoter, and maintaining the pressure in the polymerization kettle till end of reaction, whereby a polyfluoroalkoxy emulsion is obtained; S4: condensing, washing, and pelleting the polyfluoroalkoxy emulsion from step S3 to obtain the polyfluoroalkoxy resin.

Abstract: Disclosed is a method for causal inference based on collective movement of active group, comprising obtaining leader time series and follower time series of the collective movement of the active group; obtaining fixed time lag, obtaining optimal fixed time lag based on the fixed time lag, obtaining aligned time lag series based on the leader time series and follower time series; relaxing the fixed time lag, updating the optimal fixed time lag based on the relaxed results; obtaining optimal aligned time lag series based on the aligned time lag series and the updated optimal fixed time lag; distorting the leader time series and the follower time series based on the optimal aligned time lag series; performing Grange Causality inference on the distorted leader time series and follower time series to obtain results of Granger Causality inference of the collective movement of the active group.
