Patent CA-2473922-A1 (CA)
Inventor: BLATTNER FREDERICK R
IPC: C12N15/10
Filed: 2003-01-22
Abstract: The present invention provides a bacterium having a genome that is genetical ly engineered to be at least 2 to about 20% smaller than the genome of its nati ve parent strain. A bacterium with a smaller genome can produce a commercial product more efficiently. The present invention also provides methods for deleting genes and other DNA sequences from a bacterial genome. The methods provide precise deletions and seldom introduces mutations to the genomic DNA sequences around the deletion sites. Thus, the methods can be used to genera te a series of deletions in a bacterium without increasing the possibility of undesired homologous recombination within the genome. In addition, some of t he methods provided by the present invention can also be used for replacing a region of a bacterial genome with a desired DNA sequence.

Abstract: According to the invention, in order to equalise and demodulate a data signa l transmitted to a receiver via a time-variant channel, the scatterer coefficients (damping, delay and Doppler frequency) causing the signal distortions in the channel are determined from the received data signal in t he receiver. In this way, the data signal is equalised and then demodulated.</S DOAB>

Abstract: An Atmospheric Pressure Chemical Ionisation ("APCI") ion source is disclosed comprising a housing 14 having a corona discharge chamber 1, a reaction chamber 2 and a passage 6 connecting the corona discharge chamber 1 to the reaction chamber 2. Reagent ions are formed in the corona discharge chamber 1 and pass to the reaction chamber 2 via the passage 6. Analyte is sprayed into a heated tube 3. Low to moderately polar analyte molecules pass from the heated tube 3 into the reaction chamber 2 whereupon the analyte molecules are ionised by interacting with reagent ions. In contrast, highly polar analytes are ionised by thermal ionisation processes within the heated tube 3 and hence highly polar analyte ions pass into the reaction chamber 2.      Analyte ions entering the reaction chamber 2 are substantially shielded from the effects of an electric field generated in the corona discharge chamber 1 as part of the process of generating reagent ions. The APCI ion source according to the preferred embodiment is able to optimally ionise a sample containing both low to moderately polar analytes and also highly polar analytes.

Abstract: The present invention relates to collagenous membranes produced from amnion, herein referred to as a collagen biofabric. The collagen biofabric of the invention has the structural integrity of the native non-treated amniotic membrane, i.e., the native tertiary and quaternary structure. The present invention provides a method for preparing a collagen biofabric from a placental membrane, preferably a human placental membrane having a chorionic and amniotic membrane, by decellularizing the amniotic membrane. In a preferred embodiment, the amniotic membrane is completely decellularized. The collagen biofabric of the invention has numerous utilities in the medical and surgical field including for example, blood vessel repair, construction and replacement of a blood vessel, tendon and ligament replacement, wound-dressing, surgical grafts, ophthalmic uses, sutures, and others. The benefits of the biofabric are, in part, due to its physical properties such as biomechanical strength, flexibility, suturability, and low immunogenicity, particularly when derived from human placenta.

Title: Lazy flushing of translation lookaside buffers
Inventor: COHEN ERNEST S
IPC: G06F12/10
Filed: 2004-10-04
Abstract: Address translation control (ATC) limits the mappings between virtual and physical addresses in order to implement a memory access policy. Each processor in a mufti-processor system maintains a translation lookaside buffer (TLB) that caches mappings to speed translation of virtual addresses. Each processor also maintains a counter. Each time a processor's TLB is flushed, the processor's counter is incremented. When a link to a page is removed from an address translation map, the counter values for all of the processors are recorded.  When that page is accessed by a processor, the recorded counter values are compared with the processor's current counter value to determine whether the processor's TLB has been flushed since the link to the page was removed from the map. An expensive TLB flush operation is delayed until needed, but still occurs early enough to prevent an invalid TLB entry from being used to violate the access policy.
