We show that for any n ≥ 2, two elements selected uniformly at random from a symmetrized Euclidean ball of radius X in SLn(Z) will generate a thin free group with probability tending to 1 as X → ∞. This is done by showing that the two elements will form a ping-pong pair, when acting on a suitable space, with probability tending to 1. On the other hand, we give an upper bound less than 1 for the...
PIWI-interacting RNAs (piRNAs) silence transposable elements in animal germ cells. In Drosophila ovaries, piRNAs are produced by two distinct pathways: the "ping-pong" amplification cycle that operates in germ cells and a ping-pong-independent pathway termed the primary pathway that mainly operates in somatic cells. AGO3, one of three PIWI proteins in flies, is involved in the ping-pong cycle i...
This paper addresses forest height estimation for boreal forests at the test site of Edson in Alberta, Canada, using dual-baseline PolInSAR dataset measured by Intermap’s single-pass system. particular is acquired both ping-pong and non-ping-pong modes, which permit forming a TomoSAR configuration, i.e., an extreme configuration tomographic processing. A approach, based on polarimetric Capon MU...
Piwi-interacting RNAs (piRNAs) silence transposons and maintain genome integrity during germline development. In Drosophila, transposon-rich heterochromatic clusters encode piRNAs either on both genomic strands (dual-strand clusters) or predominantly one genomic strand (uni-strand clusters). Primary piRNAs derived from these clusters are proposed to drive a ping-pong amplification cycle catalyz...
The purpose of this paper design makes use of integration of PLC controller and speech via a touch screen for personalized balls adjustment of sports equipments. The athletes may adjust their requirement according to their physical condition. The system applies speech recognition Onto Ping-Pong pitching machine and controls the users’ command of speedy, slow, left or right. The athletes can pra...
In this paper, the convergence behavior of linear parallel interference cancellation is investigated. Especially the so-called ping-pong effect, where the bit-error rate performance is found to oscillate between two different convergence patterns is studied in detail. This effect is shown to be a direct consequence of the extreme eigenvalues of the correlation matrix, allowing for an analytical...
