  • Patent number: 12109336
    Abstract: The present invention aims to provide a cervical canal sealant that can be used as a sealant to stop bleeding in the uterus and vaginal discharge, particularly, a cervical canal sealant that can block the cervical canal to inhibit amniotic fluid leakage and that can also be peeled off without damaging reproductive tissue. The present invention relates to a sealant for reproductive organs in which a cured product (X) at 25° C. has a storage modulus G? of 200 to 2,000 kPa, the cured product (X) being a cured product obtained by curing the sealant for reproductive organs to a thickness of 120 to 150 ?m.

  • Patent number: 11895146
    Abstract: Provided is an infection-spreading attack detection system and method, as well as a program enabling an occurrence of an infection-spreading attack to be detected with high accuracy. A first feature amount is calculated based on traffic information on a packet transferred by a transfer device, and M partial address space(s) are identified to be a monitoring target based on the first feature amount. A second feature amount is calculated for each of the M partial address space(s) based on the traffic information related to the M partial address space(s). Abnormality detection determination is performed on each of the M partial address space(s) based on the second feature amount. Whether the infection-spreading attack has occurred is determined by evaluating M determination results.

  • Patent number: 11863584
    Abstract: An occurrence of an infection-spreading attack and an attack source thereof are detected with high accuracy. A first feature value is calculated based on traffic information regarding a packet forwarded by a forwarding device, and M partial address spaces to be monitored are specified based on the first feature value. A second feature value is calculated for each address of a terminal in a network, based on traffic information regarding the M partial address spaces, the second feature value is learned to classify terminal addresses into a plurality of clusters, and whether or not each of the clusters is an infection-spreading attack is determined to generate cluster information. Whether or not an infection-spreading attack has occurred and an address of a terminal that is an attack source are specified based on the second feature value and the cluster information.

  • Patent number: 10544425
    Abstract: By a QTL analysis and so forth using 4-HPPD inhibitor-susceptible rice and 4-HPPD inhibitor-resistant rice, a hypothetical gene (HIS1 gene) of an iron/ascorbate-dependent oxidoreductase gene located on a short arm of chromosome 2 of rice has been identified as a 4-HPPD inhibitor-resistance gene. Further, it has also been revealed that a homologous gene (HSL1 gene) of the HIS1 gene is located on chromosome 6 of rice. Furthermore, it has been found out that utilizations of these genes make it possible to efficiently produce a plant having increased resistance or susceptibility to a 4-HPPD inhibitor and to efficiently determine whether a plant has resistance or susceptibility to a 4-HPPD inhibitor.
