Several hepatitis A virus (HAV) and norovirus (NV) outbreaks due to consumption of berries and vegetables have been reported during recent years. To facilitate the detection of enteric viruses that may be present on different fresh and frozen products, we developed a rapid and sensitive detection method for HAV, NV, and rotavirus (RV). Initial experiments focused on optimizing the composition o...

—Over low bit rate channels, we adopt the streaming of nonlinearly sampled video frames (i.e., key-frame slideshow) synchronized with the audio stream. Given the channel and buffer limits, we wish to obtain a set of sampled frames that is not only feasible (i.e., no frame drop) but also optimal in terms of maximal information flow (given that the semantic information contents of each frame can ...

Proteins labeled with a luminescent lanthanide chelate, {{2,2',2'',2'''-{4'-{[(4,6-dichloro-1,3,5-triazin-2-yl)amino]biphenyl-4-yl}-2,2':6',2''-terpyridine-6,6''-diyl}bis(methylenenitrilo)}tetrakis(acetato)}europium(III) (DTBTA-Eu(3+)),were analyzed with sodium dodecyl sulfate-polyacrylamide gel (SDS-PAGE) slab gel electrophoresis and hydroxyethyl cellurose gel capillary electrophoresis with a ...

Capillary zone electrophoresis with UV detection was applied to the simultaneous determination of thiabendazole, prochloraz and procymidone in grapes. Electrolyte conditions such as pH, composition and concentration of the buffer, addition of organic solvent and working voltage were checked to obtain a high-performance separation of the three fungicides (by measurement of separation efficiency ...

With the falling price of the memory, an increasing number of multimedia servers and proxies are now equipped with a large memory space. Caching media objects in the memory of a proxy helps to reduce the network traffic, the disk I/O bandwidth requirement, and the data delivery latency. The running buffer approach and its alternatives are representative techniques to cache streaming data in the...

We have employed a rapid and highly efficient on-line preconcentration method, cation-selective exhaustive injection and sweeping micellar electrokinetic chromatography (CSEI-sweeping-MEKC), for the analysis of selective serotonin reuptake inhibitors (SSRIs) of antidepressant drugs. We monitored the effects of several of the CSEI-sweeping-MEKC parameters - including the pH, the concentrations o...

Presented in this paper are: 1.) lower bounds on energy consumption of noisy digital gates and 2.) the concept of noise tolerance via coding for achieving energy efficiency in the presence of noise. A discrete channel model for noisy digital logic in deep submicron technology that captures the manifestation of circuit noise is presented. The lower bounds are derived via an information-theoretic...

A simple, highly sensitive, isocratic stability indicating reversed phase-high performance liquid chromatography (RP-HPLC) method with UV detection at 247 nm was developed and validated for analysis of Atorvastatin (AT). Diclofenac was used as an internal standard (IS). Retention times of the AT and diclofenac (IS) were found to be 4.2 and 8.2 min, respectively. A mobile phase consisting of 0.0...
