Abstract: The present invention provides a mobile object detection method, and a mobile object detection system, that allow detecting the movement of an object based on measurements of the electric field intensity generated by transmitters such as IC tags, while curbing implementation costs. Movement of the object is detected by measuring electric field intensity generated by a plurality of transmitters arranged in a detection space, obtaining a difference between the electric field intensity and an average value of the electric field intensity in a state where an object in the detection space is not moving, and detecting the movement of the object when the difference is equal to or larger than a threshold value based on a standard deviation of the electric field intensity in a state where the object in the detection space is not moving.

Abstract: A codeword retransmission/decoding method and transmission/receiving apparatus uses feedback information. When a failure to decode data received from a receiving node occurs, the feedback information including success/failure information of the decoding and retransmission information are transmitted to a transmission node. The retransmission success probability may be increased when the retransmission feedback information is configured by the receiving apparatus repeating code-bits of the codeword just previously transmitted so as to demodulate the retransmission part.

Abstract: We have now discovered that eukaryotes, including mammals, have a DNA mismatch repair pathway analogous to the pathway that exists in bacteria. Defects or alterations in this mismatch repair pathway in a mammal, such as a human, will result in the accumulation of unstable repeated DNA sequences. Such a phenotype has a high correlation to disease state in a number of cancers, such as hereditary colon cancers. Accordingly, discovering a defect or alteration in the pathway can be diagnostic of a predisposition to cancer, and prognostic for a particular cancer.

Abstract: A method of enhancing progenitor cell differentiation, including enhancing myogenesis, neurogenesis, and hematopoiesis, by contacting a progenitor cell with an effective amount of a deacetylase inhibitor (DI). The progenitor cell can be part of cell culture, such as a cell culture used for in vitro or in vivo analysis of progenitor cell differentiation, or can be part of an organsism, such as a human or other mammal. Contacting the progenitor cell with a DI can lead to enhancement of expression of terminal cell-type specific genes in the progenitor cell, such as enhancing expression of muscle-specific genes in myoblasts. Administering a DI to a subject also can provide some prophylactic or therapeutic effect for inhibiting, preventing, or treating associated with a degeneration or loss of tissue. The DI can be administered to a subject as part of a pharmaceutical composition.
