Title: Novel dna cloning method
Inventor: BUCHHOLZ FRANK
IPC: C12N1/21
Filed: 1998-12-07
Abstract: The invention refers to a novel method for cloning DNA molecules using a homologous recombination mechanism between at least two DNA molecules comprising: a) providing a host cell capable of performing homologous recombination, b) contacting in said host cell a first DNA molecule which is capable of being replicated in said host cell with a second DNA molecule comprising at least two regions of sequence homology to regions on the first DNA molecule, under conditions which favour homologous recombination between said first and second DNA molecules and c) selecting a host cell in which homologous recombination between said first and second DNA molecules has occurred. In particular, it relies on the use of the E. coli RecE and RecT proteins, the bacteriophage Red-alpha and Red-beta proteins, or the phage P22 recombination system. The beneficial effects of concomitant expression of the RecBC inhibitor genes (e.g. Red-Gamma) is also examplified.

Patent CA-2329484-A1 (CA)
Inventor: HUANG SHAY-JAN
IPC: G10L25/00
Filed: 2000-02-18
Abstract: The invention comprises an efficient system and method for performing the modified discrete cosine transform (MDCT) in support of time-domain aliasing cancellation (TDAC) perceptive encoding compression of digital audio. In one embodiment, an AC-3 encoder performs a required time-domain to frequency-domain transformation via a MDCT. The AC-3 specification presents a non-optimized equation for calculating the MDCT. In one embodiment of the present invention, an MDCT transformer (230) is utilized which produces the same results as carrying out the calculations directly as in the AC-3 equation, but requires substantially lower computational resources. Because the TDAC scheme requires MDCT calculations on differing block sizes, called the long and short blocks, one embodiment of the present invention utilizes complex-valued premultiplication and postmultiplication steps which prepare and arrange the data samples so that both the long and short block transforms may be computed with a computationally efficient FFT. The premultiplication and postmultiplication steps are carefully structured to work with FFT's in a manner which will give the same numeric results as would be achieved with a direct calculation of the MDCT.

Filed: 2001-02-12
Abstract: The invention is concerned with a method of forming a single crystal of a ceramic, semiconductive or magnetic material. The method according to the invention comprises the steps of (a) compacting a nanocrystalline powder comprising particles having an average particle size of 0.05 to 20 µm and each formed of an agglomerate of grains with each grain comprising a nanocrystal of a ceramic, semiconductive or magnetic material; and (b) sintering the compacted powder obtained in step (a) at a temperature sufficient to cause an exaggerated growth of at least one of the grains, thereby obtaining at least one single crystal of aforesaid material. Instead of sintering the compacted powder, it is also possible to contact same with a template crystal of the aforesaid material, and to heat the compacted powder and template crystal in contact with one another so as to cause a sustained directional growth of the template crystal into the compacted powder, thereby obtaining a single crystal having a size larger than the template crystal. By using nanocrystalline powders, the temperature of operation for crystal growth is reduced, the rate of crystal growth increases, and crystals with large size and with very little or no porosity or inclusions can be obtained.
Patent CA-2336636-A1 (CA)
Inventor: TURSKI ZYGMOND
IPC: H01Q1/24
Filed: 1999-06-08
Abstract: Wireless local loops include primarily non-vertically polarized antennas.  Preferably, the wireless local loop includes horizontally polarized antennas.  By using primarily non-vertically polarized antennas in the WLL, interference between cellular, satellite and/or other radiotelephone communications systems, which employ predominantly vertically polarized antennas, can be reduced and preferably minimized. Conventional cellular and satellite radiotelephone systems use vertically polarized transmissions due to the vertical nature of the orientation of the mobile antennas on vehicles and/or mobile radiotelephones. However, in a WLL, with its fixed wireless telecommunications, there is no need to use vertically oriented antennas.  Accordingly, to reduce interference, antennas that are primarily non-vertically polarized are used.
