摘要:
A THz reverse micromagnetron includes a MEMS-based reverse magnetron configuration in which the anode is located at the center of the magnetron surrounded by a cathode ring. Electrons move radially inward in the combined electric and magnetic cross-fields and can reach orbiting angular frequencies in the THz region, even with a magnetic field of the order of 1 T or less. The THz reverse micromagnetron is portable, operates at room temperature, and can be bright.

The present invention relates to a method of detecting the presence or absence of herpes simplex virus (HSV) in a sample based on amplifying a portion of the Glycoprotein G(US4) gene of HSV and detecting the presence of the amplified nucleic acid using primers and detector primers as described herewith. The method of the invention further identifies the type of HSV, either HSV-1 or HSV-2, in a sample. Also encompassed by the invention is a kit comprising the primers and detector primers which may be used with the amplification method described herewith.

A two component highly portable and lightweight system for extending the transmission capabilities of Land Mobile Radio systems into areas lacking coverage due to structures, depth below the earth's surface, or varying terrain or other dead zones lacking coverage. The system utilizes the Radio over IP protocol to transfer two-way audio from one radio to another radio for re-broadcast inside a dead zone over a 900 MHz Ethernet-based point-to-point wireless link. The novel system includes RF to TCP/IP conversion and digital data transmission followed by a TCP/IP conversion to RF radio link and provides components and a method for bridging RF radio into dead zones.

A system and method for managing logical versions of a filesystem made through a near-instantaneous copy process is provided. Each logical version of the filesystem, including the primary version, is assigned a unique epoch number or other identifying value, and each filesystem object is assigned two epoch numbers that define the space of logical versions for which the object exists. A list of all valid epoch numbers are maintained in a version table. The near-instantaneous creation of a logical version of the filesystem requires inserting a unique epoch number entry in the version table (106) and the next epoch number to the new logical version. An original state of the system is preserved through the use of a copy-on-write procedure for filesystem objects that are reference by that logical filesystem version (120). Accordingly, filesystem versions are maintained and original states of previous states of the logical filesystem versions are preserved.

A process for quiescing a master and a plurality of subordinate computer systems in a cluster. An original or a pending state may be entered that is a quiesce or an online state. The master instructs the subordinates the quiesce or online state be made the pending state. The subordinates prepare to change accordingly, determine whether successful, and vote to commit or abort. Based on whether all voted to commit, the master instructs the subordinates to either commit or abort. If to commit and the pending state is the quiesce state, an operation is performed in the subordinates. If to commit and the pending state is the online state, the subordinates prepare to resume the original state. The subordinates change from the original to the pending state. Otherwise, if to abort, the subordinates prepare to remain in the original state and reset the pending to the original state.
摘要:
Various copy-on-write implementations for a computing environment are presented. One copy-on-write implementation includes employing a read mapping table to perform a first virtual block to physical block mapping for use in reading a block of data of a file to be copy-on-written from physical storage for modification; and employing a different, write mapping table to perform a second virtual block to physical block mapping for use in writing a modified block of the file data to physical storage, wherein copy-on-write of the block of data is achieved using a single write operation. In another implementation, a distributed copy-on-write of a file for a client server environment is presented. This distributed copy-on-write includes performing, by a first client, copy-on-write of at least one block of data of the file to be copy-on-written, and performing, by a second client, copy-on-write of at least one other block of data of the file, wherein multiple clients perform the copy-on-write of the file.
