Abstract: A congestion prediction device, a congestion prediction method, and a storage medium are provided. A mapping outputs an output variable when input variables are input to the mapping. The output variable indicates a degree of congestion in a predetermined specific area. The mapping is learned in advance by machine learning. The input variables include congestion variables. Each of the congestion variables indicates a degree of congestion in the specific area at regular time intervals within a specific period. The output variable indicates a degree of congestion after a lapse of the regular time interval from an end time of the specific period.

Abstract: Provided is a novel compound that has an excellent ?-lactamase inhibitory effect. More specifically, provided is a compound represented by formula (1a), (1b) or (11) having an excellent ?-lactamase inhibitory effect or a pharmaceutically acceptable salt thereof. By using this compound either in combination with a ?-lactam drug or alone, a useful preventive or therapeutic agent for bacterial infections is provided. Also provided are useful preventive or therapeutic agents for treating various diseases with the combined use of the aforesaid compound and ?-lactam drugs.

Abstract: Provided is a black heart malleable cast iron and a method for manufacturing the same which can significantly shorten the time required for graphitization, as compared with the prior art. The black heart malleable cast iron includes a matrix of ferrite and lump graphite included in the matrix, and includes at least one selected from the group consisting of (i) 0.0050% by mass or more and 0.15% by mass or less of bismuth and 0.020% by mass or more of manganese, and (ii) 0.0050% by mass or more and 1.0% by mass or less of aluminum and 0.0050% by mass or more of nitrogen. In addition, the grain size of the matrix is 8.0 or more and 10.0 or less in terms of grain size number, numerically determined by comparison between a metallographic photograph of the matrix and a standard grain size chart.
