Abstract: A nucleic acid fragment including a polymerase binding sequence and a transposase binding sequence, in which the polymerase binding sequence or the transposase binding sequence contains a caged nucleotide residue; a specific binding substance; a method for binding a polymerase or a transposase to the nucleic acid fragment; a method for inserting the nucleic acid fragment in a vicinity of a binding region of a DNA-binding protein bound to a DNA molecule; and a method for gene-amplifying the DNA molecule into which the nucleic acid fragment is inserted are provided.

Abstract: An oligonucleotide includes an additional sequence for detecting a nucleic acid. At least one nucleotide in the additional sequence is modified with a photolabile protecting group.

Abstract: To easily recognize a situation where confidential information has leaked from an information system. A risk management support server 400 that is connected, via a communication network, to an information system 100 managing confidential information includes a fictitious code request receiving unit configured to receive, from the information system 100, a request to acquire a fictitious code to be set in a part of items in the confidential information as well as a type of the item, a fictitious code generation unit configured to generate the fictitious code corresponding to a data format of the received type of the item, and a fictitious code providing unit configured to transmit the generated fictitious code to the information system 100.

Abstract: [Problem] To reduce the size of a linear actuator motor without increasing the operating noise thereof, and to thereby achieve a quieter, more compact linear actuator. [Solution] A linear actuator including: a shaft that is rotated in the forward and reverse directions by a motor via a double start worm and a worm wheel; a screw nut that is screwed and mounted to the shaft; and a piston tube that is fixed to the screw nut and that advances or retreats in accordance with the rotation of the shaft. The motor includes: a four-pole magnet; an armature formed by lap winding an armature coil; a commutator; brushes that are vertically arranged at positions offset by approximately 90°; and an equalizer for connecting coils in the armature coil that are to undergo potential equalization.
