  • Publication number: 20250157572
    Abstract: The purpose of the present invention is to improve the efficiency and convenience of analyzing the degree of likelihood that a mutation is one that affects the development or progression of a disease. A common filter unit of an analysis device for selecting a cancer driver mutation in a subject classifies, on the basis of a first classification criteria, each of a plurality of sequence mutations identified by sequencing nucleic acids included in the subject into a rank from among rank MYC1 for which the likelihood of being selected as a target sequence mutation is the highest and ranks MYC2 to MYC4 for which the above likelihood is lower than that for MYC1. A parameter-setting reception unit sets, as a second classification criteria, a classification criteria of having been registered in a database or a list, the second classification criteria being different from the first classification criteria for carrying out classification into rank MYC1.

  • Patent number: 6152570
    Abstract: A light incident into a wedge type light scattering conducting element from a light incident surface of the light scattering conducting element is converted into a light flux having a directionality and is output from a light output surface. The output light is input to a wedge type emitting direction characteristic adjusting element arranged with a positional relationship complementary to the light scattering conducting element. A prism shaped irregularity for adjusting a propagating directionality of the light in longitudinal/transverse directions is formed on a light input surface/light output surface of the wedge type emitting direction characteristic adjusting element. The wedge type emitting direction characteristic adjusting element has a weakened scattering power depending on requirements, thereby a degree of directionality sharpness of the light emitted from a surface light source device is adjusted.
