20080288195SYSTEM AND METHOD FOR AUTOMATION OF HARDWARE SIGNAL CHARACTERIZATION AND SIGNAL INTEGRITY VERIFICATION - A PCB comprising two or more components, such as ICs, comprises drivers and receivers that facilitate communication of signals between the components. Signal terminations, such as series and AC terminations, are used to increase the integrity of signals transmitted between components. Advantageously, values of the terminations are determined using a computerized method comprising sequential adjustment of on-chip programmable resistors and/or capacitors on chips coupled to the PCB. Thus, the effect of various values of on-chip termination resistors and/or capacitors on signal integrity is actually tested on the PCB, rather than simulating using software, for example, in order to determine optimal termination values. Characteristics of on-chip programmable resistors and/or capacitors may be adjusted by writing values into registers of the corresponding chips. The termination testing may be performed at various temperature and humidity settings corresponding to expected use environments in order to observe signal integrity at specific use environments.11-20-2008

This device comprises a first current generator for supplying a driving current to the laser source in view of producing the laser signal. A phase noise detector is responsive to the laser wavelength for generating a phase error signal and a second current generator is responsive to the phase error signal for generating a compensation current added to the driving current supplied to the laser source for generating a phase-adjusted laser signal.

20080299105Inhibition of Feline Calicivirus - We conducted feline calicivirus (FCV) inhibition experiment with two anti-viral aminohydrolases, asparaginase and glutaminase. We found that in the presence of 8 units and 4 units/ml of asparaginase, about 90% of FCV replication was inhibited. In contrast, glutaminase showed no significant inhibition effect on the virus replication. We have also shown that asparaginase did not inhibit the replication of adenovirus suggesting that the inhibition was specific. Our results implicated that asparaginase could be used as a candidate for anti-FCV drug development.12-04-2008

20110112195Potent and Selective Inhibition by Aurinticarboxylic Acid - The severe acute respiratory syndrome virus (SARS) is a coronavirus that instigated regional epidemics in Canada and several Asian countries in 2003. The newly identified SARS coronavirus (SARS-CoV) can be transmitted among humans and cause severe or even fatal illnesses. As preventive vaccine development takes years to complete and adverse reactions have been reported to some veterinary coronaviral vaccines, anti-viral compounds must be relentlessly pursued. In this study, we analyzed the effect of aurintricarboxylic acid (ATA) on SARS-CoV replication in cell culture, and found that ATA could drastically inhibit SARS-CoV replication, with viral production being more than 1000 fold than that in the untreated control. ATA is also shown to be an effective anti-viral for several other viruses, including West Nile Virus and variola virus.05-12-2011

20090205795Combined process of peroxide bleaching of wood pulps and addition of optical brightening agents - A process for improving optical properties of high-yield pulp (HYP) for producing paper products with superior brightness. Optical brightening agents (OBAs) can effectively improve the optical properties of high-yield pulp (HYP). The present process involves incorporating the OBAs into the alkaline peroxide bleaching process. By combining peroxide bleaching with an optical brightening agent, one can decrease the bleaching cost to reach the same brightness target. Some key advantages of adding OBA to HYP at the pulp mill over the conventional wet-end addition of OBA include: i) the quenching effect on OBA by the wet-end cationic polymers such as PEI is decreased by fixing OBA on HYP fibers; ii) the negative impact of metal ions in the white water system on the OBA performance is minimized when OBA is pre-adsorbed and fixed on HYP fibers; iii) the photo-yellowing (color reversion) of HYP and HYP-containing paper sheets is decreased when more OBA is on HYP fibers to protect them from harmful UV radiation.08-20-2009
