We settle a conjecture concerning necessary conditions for finite mean steady-state customer delay at the second node of a tandem queue, using as an example a stable tandem queue with mutually independent i.i.d. interarrival and service times. We assume that the service times have infinite variance at the first node, finite variance at the second node,

We derive convexity results and related properties for the value functions of tandem queuing systems. The results for standard multiserver queues are new. For completeness, we also prove and generalize existing results on tandems of controllable queues. The results can be used to compare queuing systems.

Tandem repeats constitute a consistent fraction of eukaryotic genomes and are given by monomers or gene clusters repeated in a head-to-tail direction. Main examples are represented by microsatellites, minisatellites, satellites, rDNA genes, and protein-coding genes.

Tandem catalysis is a growing field that is beginning to yield important scientific and technological advances toward new and more efficient catalytic processes. 'One-pot' tandem reactions, where multiple catalysts and reagents, combined in a single reaction vessel undergo a sequence of precisely staged catalytic steps, are highly attractive from the ...

Tandem Plasmapheresis and Hemodialysis
Therapeutic Apheresis, 2001Abstract: Many patients requiring plasmapheresis (PE) have renal failure and also need hemodialysis. If done separately almost 6–7 h is required. Hence, we decided to perform the procedures simultaneously in those patients requiring both PE and hemodialysis. The plasmafilter was inserted into the extracorporeal circuit after the hemodialyzer.
