The Genomic Virtual Laboratory (GVL) presented here was developed for automate analysis of data retrieved from a microarray experiment. The system was implemented for R Bioconductor-based analysis of results obtained in the study on human acute myeloid leukaemia (AML). The article extends the theoretical aspects of GVL presented earlier [8] and describes how the particular elements were integrated to establish the advanced system of two-colour microarray data analysis

An estimation is obtained for the asymptotic behavior of the number of multidimensional partitions into sums of various powers of integers. The obtained results are shown to reproduce the known ones for linear summands

It will also open the possibility to promote locally the content produced in other countries and host/deliver it for better end-user experience. In the paper we present the principles and conceptual design of country-wide service for interactive delivery of HD television within the PIONIER network. The concept covers five functional components which we are describing: media production, digital media repositories, live virtual channels creation and management, scalable content delivery, interactive application-on-demand provisioning (AoD)

Our numerical investigations demonstrate a spectro-temporal evolution in the broadband Cr3+: LiSAF laser emission from Fabry-Perot resonator and particularly, from a low – Q resonator. Furthermore, the resonator transient and the phenomenon of relaxation oscillations in the solidstate Cr3+: LiSAF laser have been studied. Interestingly, using a diode-pump pulse of 100 μs at 670 nm, a stable generation of single nanosecond Cr3+: LiSAF laser pulse at 850 nm is obtainable by simple choices of resonator parameters such as photon-cavity time and pump level. A pulse compression factor of 1 000 is achievable. As a result, a simple technique of short laser pulse generation at a high repetition rate of diode pumping pulses has been proposed
