Abstract: One aspect of the present invention is a refrigerating machine oil comprising a base oil, a dithiophosphoric acid ester, and a phosphonate ester.

Abstract: Provided are an information selection system, an information selection method, and an information selection program for efficiently and appropriately selecting information for use in information processing. A control unit of an assistance server generates a plurality of analysis models, using one or more pieces of information among information constituted by a plurality of pieces of training data, and calculates the accuracy of each of the analysis models. The control unit assigns distribution values according to each accuracy to information used for generating the analytical models, calculates statistics of the distribution values, for each piece of information used for generating the analytical models, and selects, using the statistics, information for use in generating the analytical models.

Abstract: One aspect of the present invention is a refrigerating machine oil comprising a base oil, a dithiophosphoric acid ester, and an amine salt of an acidic phosphoric acid ester.

Abstract: A control unit of a support server identifies, with respect to input data, a nearby node among existing nodes. The control unit calculates the distance between the input data and the nearby node. If the distance is greater than a maximum distance, the control unit uses the input data to add a new node to the existing nodes, and updates the activity value and the age of the new node and the nearby node in accordance with the distance to the nearby node. The control unit generates a self-organizing map by using the activity value of each node and the activity value of each path to calculate an age-based degree of activity, and by determining the presence or absence of each node and each path according to the degree of activity.

Abstract: An image reading apparatus includes a transparent member including a document placing surface on which a document is placed, a document pressing portion that presses the document placed on the transparent member against the transparent member, a pivot supporting portion that pivotably supports the document pressing portion so as to be pivotable about a pivot shaft with respect to a casing of the image reading apparatus, an image reading unit, an abutment portion against which an edge portion of the document placed on the document placing surface is abutted in order to position the document at a reference position, and an inclined surface. The abutment portion is provided at one portion of a front end on a side far from the pivot supporting portion. The inclined surface is provided at another portion of the front end and inclined upward toward the side far from the pivot supporting portion.

Abstract: Cyclic compounds that selectively inhibit KRAS were found. Moreover, cyclic compounds were found to interact with an amino acid residue specific to KRAS.

Abstract: A document supporting portion includes a first supporting portion and a second supporting portion. The first supporting portion has a first supporting surface that supports a document. The second supporting portion has a second supporting surface that supports the document together with the first supporting surface and provided so as to be slidable between a first position at which the second supporting portion located above the first supporting portion and a second position at which the second supporting surface supports the document together with the first supporting surface. In a state where the second supporting portion is located at the first position, the second supporting surface constitutes a portion of an upper surface of the document feeding apparatus.

Abstract: A differential amplifier includes: a constant current source; first and second field effect transistors whose respective gates are imparted with positive-phase and negative-phase input signals and whose sources commonly connected to each other, the constant current source being connected to a common node of the sources; first and second loads serving as current paths for respective drain currents of the first and second field effect transistors; an amplifying unit which outputs positive-phase and negative-phase output signals which are amplified in response to the respective drain voltages of the first and second field effect transistors; and a current path generator which generates first and second current paths parallel to the respective first and second field effect transistors for a predetermined period of time at the time of start-up of the differential amplifier.
