Title: Amplification of nucleic acids
Inventor: OULTRAM JOHN DOUGLAS
IPC: C12Q1/6853
Filed: 1998-08-12
Abstract: The present invention relates to a method of amplifying a nucleic acid sequence present in a first strand of a double stranded nucleic acid molecule wherein said molecule incorporates an unmodified recognition site for a restriction enzyme capable of cutting the first strand at the 5' end of the sequence therein to be amplified and leaving the 3'-end region of the second strand projecting beyond the cut site in the first strand. The method further comprises treating said molecule with said enzyme in the presence of a strand displacing polymerase and unmodified nucleotides for incorporation in an extending nucleic acid strand such that there is or becomes hybridised to said 3'-end region of the second strand a primer sequence complementary thereto whereby said primer sequence is extended in the 5' to 3' direction using the second strand as a template to regenerate the restriction endonuclease cut site and displace the sequence to be amplified.

Patent CA-2325446-A1 (CA)
Inventor: AHMAVAARA KALLE
IPC: H04B7/02
Filed: 1999-03-31
Abstract: The invention is directed to a method for controlling delays in a cellular telecommunications network. The delay control method according to the invention is based on a hierarchical structure of delay controlling entities, which preferably communicate only with entities directly above or below them in the hierarchy. In the downlink direction, an entity receiving data, such as a base station or a splitting unit, sends a timing report to the entity sending the data if the data is received too early or too late, whereafter the sending entity may adjust the sending time of data. The same reporting and adjusting process may be repeated through all levels of the control hierarchy, resulting in a collective control of delays from the top of the hierarchy, for example from a RNC, to the bottom, for example to a base station. In the uplink direction, a higher level entity receiving data from a lower level entity may command the lower level entity to adjust the sending time, if the data is received too early or too late. When the same action is repeated in all levels of the hierarchy, a collective control of delays is achieved for the link between the lowest level, e.g. the base station, and the highest level, e.g. a RNC.

Abstract: A distributed memory type parallel computer and a write data transfer end confirming method of the distributed memory type parallel computer, in which a series of processes to confirm a write data transfer end between plural computing nodes can be made in high speed, are provided. A computing node in the distributed memory type parallel computer provides a request accepting section, a data accepting section, an arbitration section, an address transforming section, a request/data outputting section, an EOT (end of transfer) judging section, and a selector. By using the EOT judging section and the selector in a remote node, a transfer end mark can be added to transfer data themselves.      Therefore, without executing processes before and after write data transfer by a CPU in a local node, an end confirmation of a write data transfer from the remote node to the local node can be realized by adding a transfer end mark to the transfer data themselves. With this, a series of the processes to confirm the write data transfer end can be executed in high speed.
