Quasi-Birth-Death Processes, Tree-Like QBDs, Probabilistic 1-Counter Automata, and Pushdown Systems
We begin by observing that (discrete-time) QuasiBirth-Death Processes (QBDs) are equivalent, in a precise sense, to (discrete-time) probabilistic 1-Counter Automata (p1CAs), and b...

A system of grabbing particles related to Galton-Watson trees
We consider a system of particles with arms that are activated randomly to grab other particles as a toy model for polymerization. We assume that the following two rules are ful...

Supporting VCR-Like Operations in Derivative Tree-Based P2P Streaming Systems
— Supporting user interactivity in peer-to-peer streaming systems is challenging. VCR-like operations, such as random seek, pause, fast forward and rewind, require timely P2P ove...
