It is a challenging task to investigate the different influence of long-range and short-range interactions on two-state and three-state folding kinetics of protein. The networks of the 30 two-state proteins and 15 three-state proteins are constructed at three length scales: protein contact networks, long-range interaction networks and short-range interaction networks, using complex networks analysis. To uncover the relationship between structural properties and folding kinetics of the proteins, the correlations of protein network parameters with protein folding rate and topology parameters contact order are analyzed. The results show that protein contact networks and short-range interaction networks (for both two-state and three-state proteins) exhibit the dasiasmall-worldpsila property and long-range interaction networks indicate dasiascale-freepsila behavior. Our results further indicate that all protein contact networks and short-range interaction networks are assortative type. While some of long-range interaction networks are of assortative type, the others are of disassortative type. For two-state proteins, the clustering coefficients of short-range interaction networks show prominent correlation with folding rate and contact order. The assortativity coefficients of short-range interaction networks also show remarkable correlation with folding rate and contact order. Similar correlations exist in protein contact networks of three-state proteins. For two-state proteins, the correlation between contact order and folding rate is determined by the numbers of local contacts. Short-range interactions play a key role in determining the connecting trend among amino acids and they influence directly the folding rate of two-state proteins. For three-state proteins, the folding rate is determined by short-range and long-range interactions among residues together.
研究远距离和短程相互作用对蛋白质两态和三态折叠动力学的不同影响是一项具有挑战性的任务。利用复杂网络分析方法,在蛋白接触网络、远程相互作用网络和短程相互作用网络三个长度尺度上构建了30个两态蛋白和15个三态蛋白的网络。为了揭示蛋白质的结构性质与折叠动力学之间的关系,分析了蛋白质网络参数与蛋白质折叠速率和拓扑参数接触顺序的相关性。结果表明,蛋白质接触网络和短距离相互作用网络(两态和三态蛋白质)表现出小世界性,而远距离相互作用网络表现出无世界性。我们的研究结果进一步表明,所有的蛋白质接触网络和短程相互作用网络都是分类型的。而一些远程相互作用网络是分类型,其他的是非分类型。对于两态蛋白,近程相互作用网络的聚类系数与折叠速率和接触顺序有显著的相关性。近距离相互作用网络的分类系数也与折叠率和接触顺序呈显著相关。在三态蛋白的蛋白质接触网络中也存在类似的相关性。对于两态蛋白,接触顺序与折叠速率的关系取决于局部接触的数量。短程相互作用在决定氨基酸之间的连接趋势中起着关键作用,并直接影响两态蛋白的折叠速率。对于三态蛋白,折叠速率由残基之间的短程和远程相互作用决定。

In existing P2P network trust models, the evaluation offered by applicant is always relatively simple, so there is lack of prior information in computing the trust value, which would weaken the rationality and objectivity of P2P model. To solve this problem, this paper proposes a novel trust model which is based on nodepsilas capability and quality. Through the definition of capability and quality, we propose multi-dimensional evaluation vectors with which we induce the method of computing the trust value. Simulation and analysis show that our novel model can provide effective trust services and is eligible to resist and distinguish the malicious nodes which are characterized by attack, conspiracy and strategy.

With two chains cooperation, the operation of closed-loop supply chain (CLSC) networks based on remanufacturing are studied. The model of CLSC networks is established. An l2 norm of the discrete-time transfer function of CLSC networks is described as a method to quantify the bullwhip effect. It is the minimum of the up bounded of the bullwhip effect. To reduce the bullwhip effect, we apply the linear matrix inequality approach to design a Hinfin control strategy in the worst case that the end customerpsilas demand is the most fluctuation. To prove it, we give a number example. The essence of the methods is that in the worst case the optimum strategy of the normal manufacturing and order are made by cooperation control of node enterprises in CLSC networks to restrain bullwhip effect. As a result, it presents a new method to study the stability of CLSC networks and restrain their bullwhip effects.

Introducing a LFMCW (linear frequency modulated continuous wave) radar altimeter system, which is modulating by the triangular wave, is a continuous wave modulation system of access to distance information through modulating the continuous wave. Comparing with the pulse radar, LFMCW radar has many advantages. It is based on the principle of electromagnetic wave propagation delay time in space to determine the height of the Earth's surface craft. a new arithmetic of processing the echo signal is put forward, in order to achieve the high precision altimetry and target detection and ensure the steady false alarm. The arithmetic adopts the manner of accumulating average through the sliding window, making use of the Doppler frequency shift.

Intelligent Classification Based on Tolerance Relations 基于公差关系的智能分类
Pub Date : 2008-12-18 DOI: 10.1109/FBIE.2008.120
P. Zhou, W. Cai
Binary relations and its operations are important in set theory. But traditional research mainly focuses on pure mathematics operations on set theory. Pansystems strengthen the research work in set theory by combining mathematics with its philosophical background. In this paper, using pansystems PMT-combination method, we re-inspect the philosophical background of binary relations and give a new interpretation of equivalence relations and tolerance relations. Tolerance relations are more generic than equivalence relations. Equivalence relations can generate a division on a given set. Tolerance relations, however, cannot to be used to divide a set directly. Based on our research on tolerance relations and equivalence relations, we propose a new method of using tolerance relations to divide a given set. Furthermore we go back to the real world and give the philosophical explanation of this new kind of division.
二元关系及其运算在集合论中是很重要的。但传统的研究主要集中在集合论的纯数学运算上。泛系统通过将数学与其哲学背景相结合,加强了集合论的研究工作。本文利用泛系统pmt组合方法,重新考察了二元关系的哲学背景,对等价关系和容差关系给出了新的解释。容差关系比等价关系更一般。等价关系可以在给定集合上产生一个除法。然而,容差关系不能直接用于划分集合。在对容差关系和等价关系进行研究的基础上,提出了一种利用容差关系划分给定集合的新方法。然后,我们回到现实世界,对这种新的划分进行哲学解释。

This paper is to determine metabolites of toluene diisocyanate (TDI) in mice and deduced the pathway for toluene diisocyanate metabolism in the organism. Toluene diisocyanate was administered to mice for 2 weeks, samples of blood, feces, and urine were taken, and the structure of the toluene diisocyanate metabolites was determined using gas chromatography-mass spectrometry (GC-MS). Conditions for TDI chromatography: Supelco PTETM-5 chromatographic column (30 mm times 0.25 mm times 0.25 mum); initial column temperature: 90degC, which was maintained for 30 min, after which the temperature was increased at a rate of 40degC/min to 280degC, which temperature was then maintained for 5.25 min; temperature for the vaporizing chamber: 250degC; carrier gas: helium flowing at 1.0 mL/min. Conditions for chromatography of TDI metabolites in the organism: 94% methyl, 4% ethenyl-bonded-phase fused-silica capillary column (30 + 2 mX 0.25 + 0.02 mm); initial column temperature: 30degC, which was maintained for 5 min, after which the temperature was increased at a rate of 80degC/min to 280degC, which temperature was then maintained for 5 min; temperature for the vaporizing chamber: 250degC; carrier gas: helium flowing at 1.0 mL/min. Conditions for mass spectrometry: EI for ionization; 70 eV for ionization energy; 280degC for connecting tube temperature; 35-350 amu for range of scanning; and 1.0 muL for sample size. The results showed 2,4-toluene diisocyanate was metabolized into 2,4-diaminotoluene, which is completely the same in male and female animals. Under the conditions selected for GC-MS, TDI metabolites in the organism can be isolated. Endogenous impurities in the blood, feces, or urine of mice do not interfere with the measurements.

This paper proposes a new method of text categorization called the clonal selection algorithm based on antibody density (CSABAD). In this method, antigen, B cell and antibody are respectively corresponded with training texts, a possible individual of classifier and the affinity between the individual and training texts. B cells consist of general cells, fresh cells and memory cells. General cells are used to store various individuals, fresh cells are used to replace the degraded general cells, and memory cells are used to record the best individuals. According to the clonal selection principle and density control mechanism, only those cells that have higher affinity and lower density are selected to proliferate. The ultimate classifier is composed with many memory cells. Considering the characters of medical information, we realize a medical text classifier based on CSABAD, and tests the system on OHSUMED data set. The experiment results show that it can obtain the better classification performance.
本文提出了一种基于抗体密度的克隆选择算法(CSABAD)。在该方法中,抗原、B细胞和抗体分别对应于训练文本、分类器的可能个体以及个体与训练文本之间的亲和力。B细胞由一般细胞、新鲜细胞和记忆细胞组成。一般细胞用于存储各种个体,新鲜细胞用于替换退化的一般细胞,记忆细胞用于记录最佳个体。根据克隆选择原理和密度控制机制,只有亲和性较高、密度较低的细胞才会被选择增殖。最终分类器由许多记忆单元组成。针对医学信息的特点,实现了基于CSABAD的医学文本分类器,并在OHSUMED数据集上进行了测试。实验结果表明,该方法能获得较好的分类性能。

Considering the characters of medical information, we realize a medical text classifier based on CSABAD, and tests the system on OHSUMED data set. The experiment results show that it can obtain the better classification performance.","PeriodicalId":415908,"journal":{"name":"2008 International Seminar on Future BioMedical Information Engineering","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128154420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At present, defect detection during the manufacturing are still finished by man, there are a lot of weaknesses by this way, such as low detection efficiency, high miss rate. All of these affect the production quality seriously and restrict the further improvement of production efficiency. This paper presents a method using Fisher classifier in computer image pattern recognition for defect detection and grade scoring of fabric, and gives the realization of software programming and testing. The test results show that the defect recognition rate is 94%.

A Modified LFM Signal in Coded Ultrasound 编码超声中一种改进的LFM信号
Pub Date : 2008-12-18 DOI: 10.1109/FBIE.2008.86

The linear nature of linear frequency modulation (LFM) waveform makes it rather insensitive to frequency shifts, a property which is of great importance in ultrasound imaging. However, relatively high sidelobes remain in the autocorrelation function (ACF). A modified FLM waveform is proposed by combining LFM with binary frequency code. This waveform maintains the linear nature of LFM and at same time low sidelobos are exhibited. Simulated results show the relation between the sidelobes reduction with the amplitude of the binary frequency code.
线性调频(LFM)波形的线性特性使其对频移不敏感,这一特性在超声成像中非常重要。然而,相对较高的副瓣仍然存在于自相关函数(ACF)中。将线性调频与二进制频率编码相结合,提出了一种改进的线性调频波形。该波形保持了线性调频的线性特性,同时显示出低副瓣。仿真结果表明了副瓣减小量与二进制频率码的幅值之间的关系。
