  • Publication number: 20230037869
    Abstract: The present invention provides a method comprising a step of estimating the kidney function of an arbitrary subject by a regression analysis which employs the amount of a D, L-amino acid in a biological sample from the arbitrary subject as an explanatory variable and employs the amount of filtrated glomeruli in the arbitrary subject as an object variable, by employing a previously determined formula (I): Y=a1·X1+a2·X2+ . . . +an·Xn+b (I) [wherein a1 to an independently represent a constant obtained by the regression analysis; X1 to Xn independently represent a variable of the amount of the D,L-amino acid which is selected by the regression analysis; and b represents a constant obtained by the regression analysis] on the basis of the Y value calculated from the amount of the D, L-amino acid in the biological sample from the object to be evaluated. Also provided is a system for carrying out the method.

  • Patent number: 10911925
    Abstract: The purpose of the present invention is to provide, in the context of the operation of base station devices defined under 3GPP specifications, an alert distribution device that sends an alert to a device as appropriate on the basis of prescribed conditions, without the alert precedingly requested for distribution being overwritten by the alert succeedingly requested for distribution. To achieve this purpose, an assessment is made when distributing a new alert on whether to delay distributing the new alert on the basis of attributes of alerts distributed in the past, and if the assessment is in favor of delaying distribution, the new alert is distributed after a delay of a prescribed length to the base station device that sends new alerts to terminal devices in place of alerts requested for distribution in the past.

  • Patent number: 10652544
    Abstract: An encoder includes processing circuitry, a block memory, and a frame memory. The processing circuitry defines at least one parameter for each of plural types of segment_ids, splits an image into blocks, assigns, to each of the blocks, segment_id according to a type of the block, among the plural types of segment_ids, and sequentially encodes the blocks. In encoding the blocks, the processing circuitry identifies segment_id of a current block to be encoded, and encodes the current block using the at least one parameter defined for identified segment_id. The at least one parameter includes seg_context_idx for identifying probability information associated with context used in context-based adaptive binary arithmetic coding (CABAC).
