Abstract: Provided is an electrolytic solution that includes: an electrolyte containing lithium salt; and a nonaqueous solvent containing cyclic alkylene carbonate and methyl propionate, the electrolyte contains lithium salt other than LiPF6 in an amount of not less than 30 mol % with respect to a total amount of the lithium salt, and the nonaqueous solvent contains 75 volume % or more of the methyl propionate.

Abstract: Provided is an imaging device capable of further suppressing color mixing between pixels. The imaging device includes: a semiconductor substrate provided with a photoelectric conversion unit for each of pixels two-dimensionally arranged; a color filter provided for each of the pixels on the semiconductor substrate; an intermediate layer provided between the semiconductor substrate and the color filter; and a low refraction region provided between the pixels by separating at least the color filter and the intermediate layer for each of the pixels, the low refraction region having a refractive index lower than a refractive index of the color filter.

Abstract: A similarity calculation unit (213) treats each of a plurality of classifications as a target classification, and calculates a similarity between a reference feature value, which is a feature value extracted from image data of the target classification, and a recognition feature value, which is a feature value extracted from recognition target data, which is image data to be recognized. An influence calculation unit (214) calculates an influence on the similarity with regard to each partial image of the recognition target data by taking as input the similarity with regard to each of the classifications and the recognition feature value. A feature identification unit (215) changes the recognition feature value in accordance with the influence.

Abstract: A smart contract (800) includes a bond issuing unit (832) and a bond collecting unit (833). The bond issuing unit (832) determines whether or not a payment amount to be paid by an exchange floor, who is a buyer, to a user, who is a seller, can be paid with a deposit amount of a deposit wallet of the exchange floor, and if the payment amount cannot be paid, issues to the user, a bond equivalent to a currency amount which is at least a part of the payment amount, stores the currency amount of the bond in a bond wallet, and registers the user in a creditor list. When there is currency-putting-in into the deposit wallet of the exchange floor, as the currency-putting-in becomes a trigger, the bond collecting unit (833) selects a creditor registered in the creditor list, and compares a put-in-currency amount with the currency amount of the bond which is issued to the creditor.
