Abstract: Provided is a regression estimation device that can improve accuracy of estimation in a case where estimation results obtained by performing a plurality of inputs are integrated to derive one estimated value. A regression estimation device includes one or more processors and one or more storage devices that store a program to be executed by the one or more processors. The one or more processors execute commands of the program to receive an input of a plurality of data items, to input the plurality of data items to a single regression model to estimate a plurality of sets of estimated values and certainties of the estimated values from the plurality of data items, and to integrate estimation results of the plurality of sets on the basis of the plurality of sets of the estimated values and the certainties of the estimated values estimated by the regression model.

Abstract: Provided are a medical image processing device, a medical image processing method, and a program that can estimate temporal information in an image to be processed even in a case where it is difficult to use information attached to the image to be processed. A medical image processing device includes one or more processors and one or more memories that store a program to be executed by the one or more processors. The one or more processors execute commands of the program to receive an input of an image generated by performing contrast imaging (1002) and to estimate an elapsed period from start of injection of a contrast agent in the image on the basis of image analysis of the image (1004).

Abstract: Provided are a contrast state determination device, a contrast state determination method, and a program that quickly, accurately, and robustly determine a contrast state even in a case where there is an organ that is not included in an image. A plurality of two-dimensional images including information of slice images of a subject at different positions are acquired from a first image series captured before or after a contrast agent is injected into the subject, an index value related to a contrast state is estimated from each of the plurality of two-dimensional images, and the contrast state of the first image series is determined on the basis of each of a plurality of the index values.

Abstract: A method of forming a thin film of material on a surface of a substrate, the substrate comprising a semiconductor, comprises: depositing a thin film of metal on the surface of the substrate, wherein the deposition is performed in an ultra-high vacuum, and wherein the substrate is at a temperature of less than or equal to 260 K during the deposition. Cooling the substrate during deposition of the thin film of metal may allow for an atomically flat and very uniform thin film to be obtained. Also provided is a device obtainable by the method.

Abstract: Provided are a medical image processing device, a method for operating a medical image processing device, and a program that achieve stable performance in property analysis on a medical image using a contrast state. A medical image generated by performing contrast imaging is acquired, a contrast state of the medical image is estimated on the basis of analysis on the medical image, and a property analysis is performed on a region of interest included in the medical image on the basis of features of the region of interest, using contrast state information indicating the contrast state of the medical image.

Abstract: An acrylic rubber composition comprising 5 to 15 parts by weight of a plasticizer having a solubility parameter SP value (by Small's method) of 8.5 to 10.5 based on 100 parts by weight of super cold resistant grade acrylic rubber having a glass transition point Tg of ?42° C. or less, wherein the acrylic rubber composition can give a vulcanizate with the TR10 value, which is an index of cold resistance, of ?42° C. or less both initially and after oil dipping. In the acrylic rubber composition, first, the ratio of an acrylate monomer that constitutes acrylic rubber is adjusted, thereby the low temperature characteristics can be maintained even in an oil contact environment. This intentionally reduces the oil resistance of the vulcanized rubber molded product, thereby increasing the amount of oil swelling into the vulcanized rubber molded product and improving the flexibility in a low temperature environment.

Abstract: The present disclosure provides an ethylene acrylate rubber composition which has all of oil resistance, heat resistance and hydrolysis resistance with good balance after molding and cross-linking, and a molded article formed of a cross-linked substance of the ethylene acrylate rubber composition. The ethylene acrylate rubber composition contains 100 parts by mass of an ethylene acrylate rubber, 10 to 50 parts by mass of a plasticizer with an SP value of 7 or more and 0.05 to 30 parts by mass of a cross-linking agent selected from polyvalent aliphatic primary amine or derivatives thereof. The content of a plasticizer with an SP value of less than 7 in the ethylene acrylate rubber is less than 0.1 parts by mass. Further, a molded article formed of a cross-linked product of the ethylene acrylate rubber composition is provided.
