background: the purpose of this comparative study was to detect superoxide dismutase (sod) activities in fasciola hepatica, f. gigantica parasites, infected and healthy liver tissues in order to determine of species effects and liver infection on sods activity level. methods: fasciola spp. parasites and sheep liver tissues (healthy and infected liver tissues), 10 samples for each, were collecte...

In this paper, we describe the uBike on-line service, primarily designed for amateur cyclists. We explain how the collective analysis of data is used to promote physical activity. The data fed into the system consists of GPS tracks captured during training sessions. Data analysis provides the basis for a range of features, including personal progress reports, group rankings and match-making of ...

In this paper we investigate disk activity caused by accesses to large databases stored on modern storage systems. We show that read and write requests do not arrive according to a Poisson process but rather show a power law behaviour. Also, the aggregated rates of requests show signs of long range dependence through convincing 1/f noise in the power spectrum of the process. We then present a n...

Translational control of gene expression is a mechanism that affects the relationship between mRNA level and protein level. Translation is commonly deregulated in human diseases such as cancer and understanding which mRNAs are targeted for translational deregulation and the mechanisms that mediate such effects is of high importance. Estimates of global translational activity has primarily been ...

Current computer vision techniques can effectively monitor gross activities in sparse environments. Unfortunately, visual stimulus is often not sufficient for reliably discriminating between many types of activity. In many cases where the visual information required for a particular task is extremely subtle or non-existent, there is often audio stimulus that is extremely salient for a particula...

In forward mode Automatic Differentiation, the derivative program computes a function f and its derivatives, f ′. Activity analysis is important for AD. Our results show that when all variables are active, the runtime checks required for dynamic activity analysis incur a significant overhead. However, when as few as half of the input variables are inactive, dynamic activity analysis enables an ...

the antioxidant activities of methanol (me), ethanol (ee), water (we) and ethyl acetate (eae) extracts of four inula helenium l. taxa (i. helenium ssp. orygalis (boiss.) grierson, i. helenium ssp. pseudohelenium grierson, i. helenium ssp. turcarasemosa grierson and i. helenium ssp. vanensis grierson) were investigated. the phosphomolybdenum assay, β-carotene–linoleate bleaching and dpph radical...
