Abstract: A storage controller receives a first transmission preset value and a first coefficient value at a first time from outside, at a phase 3 stage of a PCIe link training and equalization, checks whether the first transmission preset value and the first coefficient value are optimal with reference to a database, transmits signals corresponding to the first transmission preset value and the first coefficient value to the outside when the first transmission preset value and the first coefficient value are determined to be optimal and transmits signals corresponding to a second transmission preset value and a second coefficient value from the database, which are different from the first transmission preset value and the first coefficient value and optimal for the phase 3 stage of the PCIe link training and equalization, to the outside when the first transmission preset value and the first coefficient value are determined not to be optimal.

Abstract: A work suit having a lifesaving function is provided where the work suit is made of two or more sheets of fabric, at least one variable contact tube keeping air in an amount smaller than a maximum capacity is formed in the uppermost part of a side of the work suit that corresponds to the girth of the body of a wearer, and when the variable contact tube gets into water, air in a lower portion is moved up by water pressure such that the thickness of an upper portion changes to the thickness when the variable contact tube is fully filled with air, so the variable contact tube come is in close contact with the body of the wearer.

Abstract: A method of operating a memory device, a first setting signal is received by a first memory device among a plurality of memory devices. The first memory device has a first storage capacity, and the memory devices may be connected to one another by a single channel. A second setting signal is received by a second memory device among the plurality of memory devices. The second memory device has a second storage capacity different from the first storage capacity. N refresh operations are performed by the first memory device based on a first refresh command and the first setting signal during a first refresh period. M refresh operations are performed by the second memory device based on a second refresh command and the second setting signal during a second refresh period. A duration of the second refresh period is substantially the same as a duration of the first refresh period.

Abstract: Disclosed is an electronic device module including a module substrate having first and second electronic device pair portions. The first electronic device pair portion may include a first and a second contact pad area and a first via area between the first and second contact pad areas. The first electronic device pair portion may also include a first layer and a second layer. The first layer may include a plurality of first lines connecting a plurality of contact pads in the first contact pad area on one side of the module substrate to a plurality of vias. The second layer may include a plurality of second lines connecting a plurality of contact pads in the second contact pad area to a plurality of vias in the via area. The second layer may also include a plurality of third lines connecting the first and second electronic device pair portions.

Abstract: A printed circuit board (PCB) has a multi-layered substrate including a plurality of signal lines and a ground voltage plate disposed below the signal lines and by which a common ground voltage is applied to the signal lines, a heat sink disposed on the multi-layered substrate, and thermal interface material interposed between the signal lines and the heat sink to transfer heat from the multi-layered substrate to the heat sink. The heat sink thus dissipates the heat generating from the multi-layered substrate and along with the ground voltage plate suppresses electromagnetic interference of signal transmitted through adjacent ones of the signal lines. The thermal interface material also serves in the design phase as a means to tune the impedance of the signal lines.

Abstract: The present invention relates to monoclonal antibodies specifically binding to a membrane antigen of human mesenchymal stem cells, hybridoma cell lines producing the same, and methods for identifying or isolating human mesenchymal stem cells using the same. The monoclonal antibodies of this invention exhibit excellent specificity to human mesenchymal stem cells, inter alia, bone marrow-derived human mesenchymal stem cells, so that it allows for the identification and isolation of human mesenchymal stem cells with much higher specificity.
