Aside from the important role of brain natriuretic peptide (BNP) in diagnosis, and differential diagnosis of heart failure, this biological peptide has proved to be an independent surrogate marker of rehospitalization and death of the fatal disease. Several randomized clinical trials demonstrated that drugs such as beta blocker, angiotensin converting(More)
This paper presents a simulation framework for structured P2P (peer-to-peer) networks, which can be utilized in research of P2P networks. The framework provides foundational modules needed in structured P2P network simulation, presents a primitive set for structured P2P network simulation, and supports developing simulation environments for variety kinds of(More)
Two kinds of parallel genetic algorithm (PGA) are implemented in this paper based on the MATLAB® Parallel Computing Toolbox™ and Distributed Computing Server™ software. Parallel for-loops, SPMD (Single Program Multiple Data) block and co-distributed arrays, three basic parallel programming modes in MATLAB are employed to accomplish the(More)
The suboptimal water quality, including the eutrophication and the pollutants of NH<sub>3</sub>, H<sub>2</sub>S as well as organic compounds, is the main reason of damaging fish resources, which are suffered by the aquaculture ponds in the north of China and result in great losses to Chinese aquatic products every year. Therefore, it is important and the(More)
During the last 10 years, dramatic progress has been achieved in the molecular basis of disease transformation of gastrointestinal stromal tumors (GISTs). Currently, GISTs are defined as KIT-positive mesenchymal tumors with specific histological characteristics that occur primarily in the gastrointestinal tract and abdomen. In terms of distribution,(More)
A new adaptive mesh simplification method based on vertex clustering is presented in this paper, which can preserve the model topology and subtle geometric features better than traditional vertex-clustering methods. Guided by the normal vectors corresponding to all vertices, the proposed method adopts a binary tree structure to split the bounding box of the(More)
With large database, the process of mining association rules is time consuming. The efficiency becomes crucial factor. By analyzing Apriori algorithm and its improvement, the improved Apriori algorithm is applied to early warning of equipment failure. Moreover, Apriori algorithm is improved by reducing the number of scanning data base and the number of(More)
Shoot pruning could cause short-term damages to vines. In response to damage, tyloses develop in shoot xylem vessels interfering free water and mineral transportation. In this study, the tylosis development at different nodes of the current-year and perennial shoots of sixty three-year-old grapevines (Vitis vinifera L.) after pruning was investigated. The(More)
This paper discusses techniques to develop the database of civil aviation Air Traffic Control (ATC) Tower scene database and optimize approaches of 3D model by virtue of the professional modeling tool -MultiGen Creator. The ATC Tower visual simulation system is established combined with Vega Prime. However, excessive amount of data make the system not run(More)
In this paper, a new type of self-adaptation mechanism for survivability is proposed. It incorporates intrusion deception and uses it for unknown attack data collection. Attack information is extracted from the collected data through behavior analysis. Different measures are taken to deal with different types of attacks to form new rules. For example,(More)
