The intensity-based ratiometric FRET (fluorescence resonance energy transfer) method is a powerful technique for following molecular interactions in living cells. Since it is not based on irreversibly destroying the donor or the acceptor fluorophores, the time course of changes in FRET efficiency values can be monitored by this method. ImageJ, a(More)
This paper deals with a retrial queueing system with a finite number of homogeneous sources of calls and a single non-reliable server, which means that the server is subject to random breakdowns depending on whether it is busy or idle. The failure of the server may block or unblock the systems's operations and the service of the interrupted request may be(More)
In wireless multihop networks each node acts as a relay for the other nodes. Consequently, the distribution of the traffic load has a strong spatial dependence. We consider a dense multihop network where the routes are approximately straight line segments. To this end we introduce the so-called line segment traversing process which defines the movement of(More)
BACKGROUND The acceptor photobleaching fluorescence resonance energy transfer (FRET) method is widely used for monitoring molecular interactions in cells. This method of FRET, while among those with the simplest mathematics, is robust, self-controlled and independent of fluorophore amounts and ratios.
