Abstract: An information processing apparatus includes at least one processor, in which the processor is configured to: for a machine learning model that uses a document data group including a plurality of document data as input and outputs output data, derive an evaluation value in the machine learning model for each document data included in the document data group.

Abstract: An information processing apparatus including: plural models including at least a first model that uses first data as input to carry out a first prediction task and a second model that uses second data as input to carry out a second prediction task different from the first prediction task, and at least one processor, in which the processor is configured to: acquire information data representing information related to a specific target; select a selection model to be used for prediction from among the plural models based on the information data; and derive a degree of importance to the specific target for each item included in the information data by using the selection model.

Abstract: In a radiation image storage panel which has a phosphor layer containing energy-storing phosphor particles, the energy-storing phosphor particles is composed of a mixture of a phosphor particle group having a relatively large median diameter and a phosphor particle group having a relatively small median diameter, the former group having a median diameter of 4 to 30 ?m, the latter group having a median diameter of 1 to 8 ?m, and the mixture having a particle size frequency distribution that satisfies the condition of: (x+y)/5>z in which x is a size frequency (%) at the peak in a larger range of the size frequency distribution curve, y is a size frequency (%) at the peak in a smaller range, and z is the lowest size frequency (%) in the range between the two peaks.

Abstract: In a method and apparatus for manufacturing ceramic green sheets, first and second long ceramic green sheets are selectively drawn out by means of first and second draw-out rollers into a commonly used punching station. In the punching station, predetermined areas of the long ceramic green sheets are punched, so that ceramic green sheet cut pieces having predetermined sizes are formed. A cut piece held by a punching head is conveyed to a lamination station adjacent to the punching station, where lamination and press-bonding are carried out.

Abstract: A radiation image storage device composed of a fluorescent sheet which contains a phosphor which absorbs a radiation energy and emits a light of ultraviolet or visible region, and a radiation image storage panel having a fluorescent layer and a radiation image storage layer, in which the fluorescent layer contains a phosphor that absorbs a radiation energy and emits a light of ultraviolet or visible region, and the radiation image storage layer contains a stimulable oxide phosphor that absorbs the light emitted by the phosphors of the fluorescent layer and the fluorescent sheet to store energy of the absorbed light and releases the stored energy in the form of a light upon irradiation with a light of visible or infrared region is favorably employed for a radiation image storing and reproducing method.

Abstract: There is provided a radiographic image conversion panel having a substrate made of a metal or an alloy, an oxide layer formed on the substrate by a vapor deposition technique such as sputtering, ion plating or ion beam assisted deposition, and a phosphor layer formed on the oxide layer by the vapor deposition technique. A method of manufacturing the radiographic image conversion panel is also provided. The radiographic image conversion panel is capable of suppressing for a long time corrosion of the surface of the substrate due to a reaction between a stimulable phosphor and the substrate through moisture and also capable of providing a radiographic image without any deterioration of the characteristics.
