Abstract: A gas sensor includes: a gas-sensitive body layer disposed above a substrate and including a metal oxide layer; a first electrode on the gas-sensitive body layer; and a second electrode on the gas-sensitive body layer, being apart from the first electrode by a gap.

At least a part of the gas-sensitive body layer is exposed to the gap. The gas-sensitive body layer has a resistance that decreases when gas containing a hydrogen atom is in contact with the second electrode.

Abstract: A variable resistance non-volatile memory element includes first and second electrodes and a variable resistance layer between the electrodes. The layer has a resistance value reversibly variable based on an electrical signal. The layer includes a first variable resistance layer that includes an oxygen deficient first metal oxide containing a first metal element and oxygen, and a second variable resistance layer that includes a composite oxide containing the first metal element, a second metal element different from the first metal element, and oxygen, and having a different degree of oxygen deficiency from the first metal oxide. The composite oxide has a lower degree of oxygen deficiency than the first metal oxide. At room temperature, the composite oxide has a smaller oxygen diffusion coefficient than a second metal oxide containing the first metal element and oxygen, and having the degree of oxygen deficiency equal to that of the composite oxide.

Abstract: To contribute to the assurance of IP reachability from an ACS to an L2CPE, in a communication system which includes an L2CPE arranged on an in-home network, an L3CPE that performs address conversion processing in L3 between the in-home network and a communication carrier network, and an ACS that is arranged on the communication carrier network and that manages L2CPE. A management device installed on a communication carrier network: receives, from an L2CPE via an L3CPE, a connection establishment message which includes a local address of the L2CPE used to access the L2CPE from the ACS; sets, in respect to the L3CPE, a correspondence between the L2CPE local address and a global address of the communication carrier network used to convert an address to the local address; and transfers, to the ACS, the message changed so the local address included in the received message corresponds to a port-mapped global address.

Abstract: A method of measuring a fluid secretion function of epithelial cells includes: seeding organoids established from epithelial cells in a culture receptacle and culturing the organoids in a gel in each well of the culture receptacle for a prescribed period of time; capturing a multi-pixel image of each organoid-containing well; detecting as organoids regions in the captured image that are regions surrounded by edges having at least a prescribed difference in pixel intensity value with respect to that of a background; calculating an area inside the edges for the object; selecting whether or not the object is an organoid-derived object; and determining whether or not an object selected as being derived from the organoid is subject to analysis. No cell staining product for staining the organoids is added when performing the imaging process.
