Abstract:
A magnetic disc used in a constant-density magnetic disc driving apparatus includes a wedge identification field following a servo information area that contains a wedge identification for identifying a plurality of data sectors located within a corresponding data information area. A pseudo identification field positioned at a first portion of each data sector represents a time interval required to generate from the wedge identification a pseudo identification that identifies a corresponding one of the data sectors and transfer the pseudo identification to a controller of the magnetic disc driving apparatus. The pseudo identification field includes a data preamble for providing data synchronization for the corresponding data sector. A data field is positioned behind the pseudo identification field, and the data field and pseudo identification field make up a single data sector. Data that is identified by the pseudo identification and synchronized by the data preamble is written in the data field.
Abstract:
A composition for delivery of a selected nucleic acid into a targeted host cell comprises a complex of a hydrophobized, positively charged, biocompatible polymer; a lipoprotein; and a selected nucleic acid. Hydrophobic and electrostatic interactions between the components provide for the formation of the condensed DNA-containing complex. Preferred embodiments of the complex have a slightly positive surface charge and an average diameter of about 200 nm. Plasmids and oligonucleotides can be efficiently delivered with such compositions. A method of delivering a selected nucleic acid to a host cell is also disclosed.
Abstract:
Disclosed herein is a Superconducting Fault Current Limiter (SFCL) for suppressing a bus voltage drop in an electric power system. A primary winding, a secondary winding, and a tertiary winding are wound around an identical iron core, and a superconductor is connected to any one of the primary winding and the secondary winding. A first switch is connected to any one of the primary winding and the secondary winding and is configured to be opened so as to separate a faulty section when a fault current is generated and to be shorted when the fault current is eliminated. A second switch is connected in series to the tertiary winding and is configured to be shorted so as to stably supply power when the fault current is generated and to be opened when the fault current is eliminated. According to the present invention, there are advantages in that a fault current is limited using magnetic coupling between two coils that are connected in a non-isolated type (in parallel or in series) or in an isolated type and in that a faulty section is separated using a switch and power is stably supplied to a section, in which a bus voltage drop has occurred due to the fault current, using a tertiary winding and a switch connected thereto, thus improving the stability of the system and obtaining economic effects.
