LDPC codes, LT codes, and digital fountain techniques have received significant attention from both academics and industry in the past few years. By employing the underlying ideas of efficient Belief Propagation (BP) decoding process in LDPC and LT codes, this paper introduces three classes of secret sharing schemes called BP-XOR secret sharing schemes, pseudo-BP-XOR secret sharing schemes, and...

This paper presents a proof of the existence of computationally fast probabilistic erasure codes at distance ǫ from being MDS, namely the decoding algorithm is able with high probability to reconstruct the n letter message from any set of (1+ǫ)n letters. It can either be fixed rate or a rateless LT code [10] in that any number of code letters can be produced and each is produced independently o...

The congestion control algorithms in TCP may incur inferior performance in a lossy network context like wireless networks. Previous works have shown that random linear network coding can improve the throughput of TCP in such networks, although it introduces extra decoding delay at the destination. In this paper we try to alleviate the decoding delay by replacing random linear network coding wit...

hepatocellular carcinoma (hcc) represents one of the most common neoplasms worldwide.  liver trasnplantation (lt) is the treatment of choice for selected group of patients with hcc. lt is actually a consolidated therapeutic option for hcc because it cures both tumor and underlying cirrhosis. in 1996, the publication of a pivotal prospective study on less than 50 patients, transplanted for hcc u...

OBJECTIVE To evaluate a possible association between neighbourhood socio-economic status and spontaneous premature birth in Alberta births. METHODS The study design was a retrospective cohort of all births in Alberta for the years 2001 and 2006. The primary outcome was spontaneous preterm birth at &lt;37 weeks gestation. Neighbourhood socio-economic status was measured by the Pampalon Materia...
