  • Publication number: 20240134077
    Abstract: A fiber sensing system according to the present disclosure includes a submarine cable, and a plurality of relaying apparatuses being connected in series to one another via the submarine cable. The relaying apparatus includes a DAS interrogator being connected to a relaying apparatus at a subsequent stage via a sensing optical fiber in the submarine cable, and a terminator being connected to a relaying apparatus at a preceding stage via the sensing optical fiber. The DAS interrogator outputs probe light to the sensing optical fiber. The terminator terminates probe light being output from the DAS interrogator in the relaying apparatus at the preceding stage to the sensing optical fiber. The DAS interrogator receives backscattered light of probe light from the sensing optical fiber, and acquires the DAS data from the received backscattered light.

  • Publication number: 20240102089
    Abstract: The purpose of the present invention is to provide a method for conveniently and accurately evaluating the ligation efficiency in the DNA sequencing process in order to optimize the condition of ligating Y-type adapters to both ends of a double-stranded DNA fragment. The present invention relates to a method for evaluating the efficiency of ligation reaction through which Y-type adapters are ligated to both ends of DNA to be analyzed, in the sequencing process of DNA to be analyzed using the Y-type adapter, wherein the efficiency of reaction is evaluated by electrophoresing a reaction mixture containing ligation molecules, between the DNA and the Y-type adapters, produced by the ligation reaction under a specified condition, and analyzing a band separated on the basis of the number of adapters ligated to the DNA.

  • Patent number: 10808152
    Abstract: The present invention aims to provide an adhesive composition which enables achievement of highly strong adhesion between a lightweight composite resin and a lightweight metal member, and which can maintain excellent adhesive strength even in cases where the ambient temperature largely changes or the adhesive composition is in contact with water or a snow-melting agent, and an adhesive sheet using it. The above object can be achieved with an adhesive composition containing at least an epoxy resin, an acrylic particle, and a curing agent, wherein the acrylic particle is a core-shell structure containing a butadiene-based rubber, and polymethacrylate or polyacrylate. The adhesive sheet is constituted such that an adhesive layer formed with the adhesive composition is present between a first release film and a second release film.
