Observations ceased on April 8 , 1998 when the temperature of the telescope's detectors rose above 4 K (−269 °C, or −452 °F), which made detecting sky sources impractical.
Typhimurium is one of the most common serotypes of Salmonella, which make detecting outbreaks more difficult in the absence of subtyping.
This may be partly be explained by the small Ne in humans (≈ 10 4 ), which may render a general reduction in efficacy of selection, which in turn makes detecting the effects of HRI harder than in species with large Ne such as Drosophila (≈ 10 6 ; Bullaughey et al. 2008).
It is however possible that the amplified uptake signal for U343 and especially A431 as observed by Sundberg et al. [14] can be explained solely by an increased affinity, since the 125I-EGF concentration tested (2 nM) is close to KD which makes the detected output highly sensitive to any affinity changes.
Although the detection process of the ARGOS system, which makes use of detected library of repeated objects, significantly increases the search efficiency, its discovery process still suffers from the exhaustive search over all the collection data.
Micromuse, which makes software to detect flaws in data networks, announced plans yesterday to acquire RiverSoft, a competitor.
"It's nice to see big players taking spyware seriously," said Ed English, the chief executive of Intermute, which makes products to detect and remove adware and spyware.
A result revealing a CK19 mRNA copy number >250, which makes sure to detect mainly macrometastases and not isolated tumour cells (ITC) or micrometastases only, was regarded as positive for lymph node metastases based on previous threshold investigations.
A spokesman for BioVeris, which makes testing systems to detect things like biowarfare agents and bacteria in food, declined comment.
"The effects of brain aging can be subtle and progress slowly, which makes them difficult to detect," he noted.
