We consider a multi-source delivery system, where Raptor coding at sources and linear network coding in overlay nodes work in concert for efficient data delivery in networks with diversity. Such a combination permits to increase throughput and loss resilie ...
We study charmless B+ meson decays to the p Lambda pi(+)pi(-) final state using a 605 fb(-1) data sample collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. There are significant signals found wit ...
Purpose: To compare early versus late enhancement in two glioblastoma models characterized by different infiltrative/ edematous patterns. Materials and Methods: Three weeks after inoculation into nude mice of U87MG and U251 cells, T1-weighted images were a ...
Digital media have become an integral part of modern lives. Whether surfing the web, making a wireless phone call, watching satellite TV, or listening to digital music, a large part of our professional and leisure time is filled with all things digital. Th ...
We present results of a detailed study of the three-body over(B, ̄)0 → Σc (2455)0 over(p, ̄) π+ decay. A significant enhancement of signal events is observed in the over(p, ̄) π+ invariant mass distribution near 1.5 GeV / c2 that is consistent with the pre ...
We present a new model for LT codes which simplifies the analysis of the error probability of decoding by belief propagation. For any given degree distribution, we provide the first rigorous expression for the limiting bit-error probability as the length o ...
This paper exhibits a class of universal Raptor codes: for a given integer k, and any real /spl epsiv/>0, Raptor codes in this class produce a potentially infinite stream of symbols such that any subset of symbols of size k(1 + /spl epsiv/) is sufficient t ...
Growth of Ru- and RuO2-composite (ROC) nanodots on atomic-layer-deposited Al2O3 film has been studied for the first time using ion-beam sputtering followed by post-deposition annealing (PDA). X-ray photoelectron spectroscopy analyses reveal that RuO2 and R ...
LT-codes are a new class of codes introduced by Luby for the purpose of scalable and fault-tolerant distribution of data over computer networks. In this paper, we introduce Raptor codes, an extension of LT-codes with linear time encoding and decoding. We w ...
This paper provides an efficient method for analyzing the error probability of the belief propagation (BP) decoder applied to LT Codes. Each output symbol is generated independently by sampling from a distribution and adding the input symbols corresponding ...
