    Abstract: A relation search system includes: a storage means (1) which stores a data set which includes a first-type data group and a second-type data group which are two types of data group that are acquired by different methods; a data adaptation means (2) which either corrects or reconstructs either first data which belongs to the first-type data group or second data which belongs to the second-type data group and which is associated with the first data, such that a divergence which arises between the first data and the second data because of the difference in the methods for the acquisition thereof is reduced; and a learning means (3) which, using the data set which includes the corrected or reconstructed data, carries out machine learning.

    Abstract: A heat-flow sensor that includes an insulating layer, a magnetic field application layer arranged on a first surface of the insulating layer and composed of a conductor, and a heat-flow detection layer arranged on a second surface of the insulating layer, the second surface facing the first surface, and the heat-flow detection layer composed of a conductive magnetic body. The heat-flow detection layer faces the magnetic field application layer via the insulating layer.

    Abstract: A combination search system includes: a storage that stores actual data in which input information indicating a combination of values taken by elements of the multi dimensions in the confirmation work in the past or in a real space is associated with output information indicating a value of the predetermined parameter obtained for the combination indicated by the input information at that time; and a search unit that repeats, a process of determining at least one combination to be used in next confirmation work on the basis of importance of information that is an index defined for each combination of the elements, the index being calculated from the actual data and being based on an amount of change in uncertainty of the value of the predetermined parameter in a whole of a search space due to that new output information for the combination is added to the actual data.

    Abstract: A thermoelectric conversion element 10 includes an anomalous Nernst material 11 having the anomalous Nernst effect, in which: the anomalous Nernst material 11 includes at least an element having the inverse spin-Hall effect; and the element is spin-polarized. By applying, for example, a magnetic field to such the thermoelectric conversion element 10 in the x direction and a temperature gradient thereto in the z direction, thermoelectromotive force can be taken out from terminals 12.

    Abstract: [Problem] To provide a heat exchange device with which efficient electric power generation can be performed while transfer of a heat amount is maintained. [Solution] A heat exchange device comprising a heat exchange section 1 and a magnetic body 2. The heat exchange section 1 includes a first heat transmission interface 3 in contact with a heat source, and a second heat transmission interface 4 in contact with a heat bath having a temperature different from that of the heat source. The magnetic body 2 is interposed between the first heat transmission interface 3 and the second heat transmission interface 4 of the heat exchange section 1, and includes a magnetization component in a direction intersecting a heat flux produced between the first heat transmission interface 3 and the second heat transmission interface 4.
