Thoracic ossification of ligamentum flavum (OLF) caused by skeletal fluorosis is rare. Only six patients had been reported in the English literature. This study reports findings from the first clinical series of this disease. This was a retrospective study of patients with thoracic OLF due to skeletal fluorosis who underwent surgical management at the(More)
Different from the traditional topic detection and tracking (TDT) technologies primarily focus on detecting topic in local network domain, this paper proposes a cooperative alert topic detection model in distributed environment (named CATDM). The model abstracts the alert topic and represents it as the local alert case by analyzing the alert of campus(More)
We present a scalable spatial decomposition coloring approach to implement molecular dynamics simulations with embedded atom method (EAM) on multi-core architectures. It effectively solves parallelization of reduction operations on irregular arrays in molecular dynamics simulations. In OpenMP program model, our methodology avoids that the same memory(More)
Aiming at the deficiencies of traditional blog hotness evaluation methods, the paper presents a blog hotness evaluation model based on text opinion analysis (named BHEM-TOA). The model not only considers the number of reviews, comments and publication time of the blog topic, but also focuses on the comment opinion. BHEM-TOA emphasizes subjective opinions of(More)
OpenMP is an emerging industry standard for shared memory architectures. While OpenMP has advantages on its ease of use and incremental programming, message passing is today still the most widely-used programming model for distributed memory architectures. How to effectively extend OpenMP to distributed memory architectures has been a hot spot. This paper(More)
Message-passing is a predominant programming paradigm for distributed memory systems. RDMA networks like infiniBand and Myrinet reduce communication overhead by overlapping communication with computation. For the overlap to be more effective, we propose a source-tosource transformation scheme by automatically restructuring message-passing codes. The(More)
In the process of treatments to large-scale 3-D prestack Kirchhoff depth migration, the required memory for imagining spaces is large, even more than the total memory of the single node. So this paper proposes the partitioning algorithm based on the process groups in the environment of distributed memory. Partitioning to the imaging spaces is going on in a(More)
