    Abstract: A sign detection device is provided with a plurality of sensors, a data acquisition unit, a calculation unit, and a detection unit. The plurality of sensors are respectively disposed at a plurality of positions of a detection target to measure a physical parameter at each positions.
    The data acquisition unit is configured to acquire time-series change data of the physical parameters from the plurality of sensors. The calculation unit is configured to calculate dynamic network information representing a time change of a complex network structure including a parameter indicating a correlation between the physical parameters at any two positions of the plurality of positions, on the basis of the time-series change data. The detection unit is configured to detect a sign of sudden change vibration of the detection target, on the basis of the dynamic network information.

    Abstract: In an encryption authentication system, a service server transmits the third encryption information to a user terminal, in a case where the service server receives a request from the user terminal. The user terminal calculates fourth encryption information and transmits the fourth encryption information to an encryption server. The encryption server and the calculation server cooperate with each other to calculate encryption information as a collation target and transmit the encryption information to the service server. The service server obtains a coincidence degree between the first plaintext information included in the encryption information as the collation target and the second plaintext information, by a collation function using a third encryption key and a second encryption key used to calculate registration encryption information, and transmits an authentication result corresponding to the coincidence degree to the user terminal.

    Abstract: A power generator includes a power generating unit and at least one of a power storage unit or an output unit that is electrically connected to the power generating unit. The power generating unit includes an electret having a first charged surface and a second charged surface that are charged with opposite polarities, a first electrode formed on the first charged surface, and a second electrode formed on the second charged surface. The electret is formed by polarizing an electret material that includes an inorganic dielectric having a bandgap energy of 4 eV or more. At least one of the first electrode or the second electrode are partially disposed on the corresponding charged surface such that at least one of the first charged surface or the second charged surface has a portion as a current collecting surface exposed outward.

    Abstract: A device which, in a shallow region including the epidermal layer or the dermal layer, can administer a target even in extremely small amounts. This includes a puncture needle which, in a flat puncture unit for puncturing the shallow region, has a groove and a through-hole which constitute a recess that extends through part of or the entire thickness of the puncture unit; and a casing which houses the puncture needle so as to allow the puncture needle to advance. By part or all of a flow agent containing the drug being arranged in the groove and the through-hole, the drug is positioned with respect to the puncture unit. The device is designed such that a flow agent in the amount of 10-1000 nL is dosed in the shallow region per puncture.

    Abstract: An enantiomer preparation method in which one enantiomer of a sulfoxide compound is selectively prepared, the sulfoxide compound having a sulfur atom of a sulfoxide group as an asymmetric center, the method including a step A for optically resolving an enantiomer mixture of a sulfoxide compound into one enantiomer and the other enantiomer; a step B for irradiating with light the other enantiomer obtained in step A or step C to racemize the enantiomer; and step C for optically resolving the enantiomer mixture of the sulfoxide compound obtained in step B into one enantiomer and the other enantiomer. A system for preparing an enantiomer which is used in the enantiomer preparation method.
