Abstract:
A method of fabricating metallic Cu nanowires with lengths up to about 25 μm and diameters in a range 20-100 nm, or greater if desired. Vertically oriented or laterally oriented copper oxide structures (CuO and/or Cu2O) are grown on a Cu substrate. The copper oxide structures are reduced with 99+ percent H or H2, and in this reduction process the lengths decrease (to no more than about 25 μm), the density of surviving nanostructures on a substrate decreases, and the diameters of the surviving nanostructures have a range, of about 20-100 nm. The resulting nanowires are substantially pure Cu and can be oriented laterally (for local or global interconnects) or can be oriented vertically (for standard vertical interconnects).
Abstract:
A semiconductor memory cell includes a floating body region configured to be charged to a level indicative of a state of the memory cell selected from at least first and second states. A first region of the memory cell is in electrical contact with the floating body region. A second region of the memory cell is spaced apart from the first region and is also in electrical contact with the floating body region. A gate is positioned between the first and second regions. A back-bias region is configured to generate impact ionization when the memory cell is in one of the first and second states, and the back-bias region is configured so as not to generate impact ionization when the memory cell is in the other of the first and second states.

Abstract:
The present invention relates to a multi-layered vitamin/mineral complex tablet having enhanced stability of ubidecarenone. The present invention is characterized in that ubidecarenone is contained in a first layer, and ingredients decreasing the stability of ubidecarenone are contained in an additional layer separated from the first layer. The method is a convenient process, and the formulation prepared by the method can maintain a high content of ubidecarenone during long-term storage, thereby providing a simultaneous intake of ubidecarenone and nutritional ingredients such as various vitamins.

Abstract:
A method and device for recognizing a pulse repetition interval (PRI) modulation type of a radar signal are provided. The method for recognizing a pulse repetition interval (PRI) modulation type includes: extracting time of arrival (TOA) information of pulses aligned in time order from a received radar signal; generating a PRI sequence based on a difference of adjacent TOAs in the TOA information of pulses; generating a difference of PRIs (DPRI) sequence by using a difference of the adjacent PRIs in the PRI sequence; generating respective symbol sequences by using specific partition rules from the PRI sequence and the DPRI sequence; and calculating characteristic factors from the symbol sequences, and comparing the characteristic factors with threshold values for discriminating a PRI modulation type to determine the PRI modulation type. Thus, the PRI modulation type, a promising feature for radar signal identification, can be precisely derived.
