Abstract: A method is provided for determining whether a difference between a first reference sequence and first comparative sequences sharing homology with the first reference sequence is caused by a mutation of the first comparative sequence or a read error in sequencing. The method includes generating second comparative sequences and a second reference sequence by substituting for a sequence having the predetermined base number of the consecutive same bases in the first comparative sequences and the first reference sequence, calculating an edit distance of the second comparative sequence to the second reference sequence, and determining whether the difference is caused by the mutation or the read error based on the edit distance.

Abstract: Each of a plurality of semiconductor light-emitting element has, on an upper surface thereof that has a quadrilateral shape, a pair of connecting portions having different polarities from each other. The pair of connecting portions are aligned on a diagonal of the quadrilateral shape.

Abstract: A lighting apparatus includes a substrate, a light-emitting element, and a sealing member. The light-emitting element emits light in a first wavelength range. The sealing member contains a material that converts the light in the first wavelength range to light in a second wavelength range different from the first wavelength range.

A curved line indicating a change in output angle that occurs upon a change in observation angle is approximated by a quadratic or trigonometric function that passes through the origin.
