Abstract: A unit configured as constituent part of a fuel cell for use in novel electrochemical hydrogen compressor material technology system includes a combination of a hydrocarbon auto-thermal reformer, a water-gas shift reactor, and at least two countercurrent flow heat recuperators at least one of which is downstream from both the reformer and reactor. Optionally, two of the at least two recuperators are separated by the reactor to generate H2 in addition to that already contained in reformate formed at the reformer. The unit may include a proton conducting membrane that includes an inorganic polymer with pores filled with an organic polymer, each of which is configured to operate individually within a wide range of temperatures with no added solvent.

Abstract: The three-state spintronic device includes: a bottom electrode, a magnetic tunnel junction and a top electrode from bottom to top. The magnetic tunnel junction includes: a spin-orbit coupling layer, a ferromagnetic free layer, a barrier tunneling layer, a ferromagnetic reference layer, three local magnetic domain wall pinning centers and domain wall nucleation centers. An antisymmetric exchange interaction is modulated, and the magnetic domain wall pinning centers are embedded in an interface between a heavy metal and the ferromagnetic free layer. The magnetic domain wall nucleation centers are at two ends of the ferromagnetic free layer. A current pulse flows through the spin-orbit coupling layer to generate a spin current and the spin current is injected into the ferromagnetic free layer. Under a control of all-electrical controlled, an effective field of a spin-orbit torque drives domain wall to move and displace.

Abstract: A method, system, and computer program product for determining customer migration: obtain first feature data for a plurality of users associated with a first time period; segment the plurality of users into a plurality of groups based on the first feature data; identify a center point of each group based on the feature data; obtain second feature data for one or more users of the plurality of users associated with a second time period; determine a distance between the one or more users and each center point of each group based on the second feature data; and assign the one or more users to a group of the plurality of groups based on the distance between the one or more users and each center point of each group.

Abstract: Provided is a computer-implemented method for linking datasets using at least two keys, including matching a second key of a first dataset with a second key of a second dataset to identify a plurality of matching records, linking the plurality of matching records from the first dataset and the second dataset, matching the first key of the first dataset with the first key of the second dataset to identify a second plurality of matching records, and linking the second plurality of matching records from the first dataset and the second dataset.
