  • Patent number: 9234897
    Abstract: Disclosed is a method for distinguishing a mesenchymal stem cell comprising, using at least one gene selected from the genes having the nucleotide sequences indicated by the accession numbers shown in Table 1 as a distinguish marker, detecting the difference in expression of the distinguish marker between a mesenchymal stem cell and a connective tissue cell to distinguish the mesenchymal stem cell from the connective tissue cell. This method enables to distinguish an undifferentiated mesenchymal stem cell from other connective tissue cell such as fibroblasts, osteoblasts, chondrocytes and adipose cells with good accuracy. A mesenchymal stem cell given by this method or a composition comprising the mesenchymal stem sell can be used as a therapeutic for use in the regenerative medicine.

  • Patent number: 8077811
    Abstract: For each of a plurality of control channels, a likelihood indicated by a state metric of each state at the last point which is obtained at the time of Viterbi decoding is obtained. This Viterbi decoding is not cut off and performed to convolutionally coded data of the corresponding control channel. The ranking of the likelihood is obtained as a possibility ranking SM0RANK indicating the possibility of the control channel to be a control channel for a particular receiving apparatus. From the plurality of control channels, the control channels with the possibility ranking SM0RANK more or equal to a predetermined threshold are selected as candidate channels. An output likelihood of each candidate channel which is obtained in the Viterbi decoding is normalized with a receiving intensity of the corresponding candidate channel to detect a candidate channel having the highest normalized output likelihood as the control channel for the receiving apparatus.

  • Publication number: 20110297059
    Abstract: A combustion apparatus has: a combustion housing; a partition plate provided in the combustion housing to partition a space in the combustion housing into a combustion chamber and an air supply chamber; and a plurality of rich-lean burners arranged in a right-left direction of the combustion chamber. A multiplicity of distributed holes are formed in the partition plate through which distributed holes secondary air is supplied from the air supply chamber to the combustion chamber. A flame rod facing to an upper side of a part of the rich-lean burners stops combustion when the flame rod does not detect any flames owing to a flame lift at a time of an oxygen deficiency. A supply quantity of the secondary air to the part of the rich-lean burners to which part the flame rod faces is larger than those to other parts.

  • Publication number: 20090327836
    Abstract: A decoding method performs turbo decoding on data that includes a first value before transmission and that includes a second value after received, the second value changed from the first value due to the influence of a transmission path. The decoding method includes performing the turbo decoding on the data to obtain a log-likelihood ratio for the second value, converting the second value to a third value that is obtained by correcting the second value to become closer to the first value when a decoded result from the turbo decoding on the data includes an error and when an absolute value of the log-likelihood ratio is equal to or greater than a predetermined threshold value; and performing the turbo decoding on the data including the third value to obtain a decoded result of the data.

  • Patent number: 5735990
    Abstract: Disclosed is a process for producing a carpet backsized with a backing composition. The composition contains a resin component with ethylene/vinyl acetate being the principle compound and an ethylene/alpha-olefin copolymer constituting the remainder. In addition, the composition includes an inorganic filler in an amount of from 25 to 75% by weight and a dispersing agent that is atactic polypropylene. This composition is formed by kneading and pelletizing the inorganic filler and dispersing agent to form a master batch which is in turn dry-blended with the resin component of the composition, followed by extrusion through T-dies into a sheet and applied, while still melted, to the underside of a carpet base material and cooled.
