This paper studies the problem of Raptor-code design for binary-input AWGN (BIAWGN) channels using the mean-LLR-EXIT chart approach presented in [1]. We report that there exist situations where such a design approach may fail or fail to produce capacity-achieving codes, for certain ranges of channel SNR. Suggestions and discussions are provided pertaining(More)
Approximate string matching technique has been widely applied to many fields such as network information retrieval, digital library, pattern recognition, text mining, IP routing searching, network intrusion detection, bioinformatics, and computing in musicology. The two concise parallel dynamic programming algorithms for approximate string matching with(More)
By allowing the overlap execution of computation and communication, a multi-round algorithm with inter-node scheduling and intra-node scheduling for divisible loads is presented on the heterogeneous cluster systems of multi-core computers, which have different number of processing cores and distinct computation, communication and memory abilities. The(More)
OBJECTIVE The aim of this study is to observe the chronic effects of diltiazem release capsules on patients with coronary slow flow (CSF) phenomenon. METHODS From 2004 to 2009, 80 consecutive patients with chest pain and normal coronary arteries evidenced by coronary angiography and CSF were included in this randomized, double-blind, placebo-controlled(More)
Problem-based learning is a popular approach in the medical profession constructivist teaching model. In this paper, the problem-based learning teaching mode is analyzed and is applied into teaching operating system course. We design problem-based teaching and learning projects, investigate the arising key problems in the teaching practice, and propose some(More)
Currently, there is still a lack of an optimal treatment for no reflow phenomenon (NRP). We analyzed the efficacy and safety of using nondihydropyridine calcium channel antagonists (NDHP, verapamil/diltiazem) in patients suffering from NRP. Eight RCTs with 494 participants were eligible for analysis. The pooling analysis showed that intracoronary(More)
BACKGROUND Aortocaval fistula (AV) in rat is a unique model of volume-overload congestive heart failure and cardiac hypertrophy. Living donor kidney transplantation is regarded as beneficial to allograft recipients and not particularly detrimental to the donors. Impact of AV on animals with mild renal dysfunction is not fully understood. In this study, we(More)
It has been widely acknowledged that regular consumption of fresh fruits and vegetables is linked with a relatively low incidence of cancers (e.g. breast, cervix, and colon). Notably, dietary polyphenolic compounds that show some structural similarity to human estrogen, e.g. isoflavones, coumestans, lignans, flavones, have been proposed to play a role in(More)
