In this study, 149 polymorphic markers were screened from 200 microsatellite markers. From a family of mirror carp, which included 107 individuals. All samples were analyzed for body correlation, and intermuscular bone number was tested using the General Linear Model (GLM) single marker regression. Determination of the threshold values by 10,000 permutation tests showed that eight markers had significant correlation (P<0.05), in which HLJ3086, HLJ3642 and HLJ3515 had very significant correlation with intermuscular bone number (P<0.01). In addition, the genotypes of the captured correlative loci were determined by Duncan's test using SPSS17.0 software. Markers were used to screen the protein and nucleotide database in the National Center for Biotechnology Information (NCBI). Blasting results showed that HLJ2891 was highly correlated (92%) with latrophilin-2-like and HLJ3515 was highly correlated (81%) with serine/threonine-protein kinase 32B-like of zebrafish. These functional markers and genotypes may provide an efficient basis for marker-assisted selection of intermuscular bone number in mirror carp. Source

This paper presents a hybrid air handling unit (AHU) fault detection strategy based on Principal Component Analysis (PCA) method and Pattern Matching method. The basic idea of the pattern matching method is to locate periods of operation from a historical data set whose operational conditions are similar to the target operating condition. The proposed Pattern Matching-PCA method uses two similarity factors, PCA similarity factors and Distance similarity factors, to characterize the degree of similarity between historical data window and current snapshot data. PCA model is then built using the historical AHU operation dataset that are identified to be similar to current snapshot operation data. The method is validated by operational data of an AHU system in real building. The results show that the sensibility of PCA models is enhanced by preprocessing the training data with the Pattern Matching method. © 2014 Elsevier B.V. Source

Abstract This paper proposes an effective analytical expression for the accurate evaluation of the effective thermal conductivity (ETC) of randomly packed granular material with high solid-to-fluid conductivity ratio. The procedure is a novel combination of two key techniques: the parallel-column model and the pipe-network model. The ETC can be predicted using the proposed expression without microscopic analysis of the granular sample. Several practical issues associated with the accuracy and efficiency of the analytical expression are discussed, and test cases are provided to illustrate the applicability of the expression. © 2015 Elsevier Ltd.

A group of F2 hybrids of mirror carp including 68 individuals was used to construct a linkage map using JoinMap4.0 software. Of 560 markers genotyped, 507 markers (143 SSR markers, 33 EST-SSR markers, and 321 SNP markers) were assigned to the map, which comprised of 62 linkage groups. Quantitative traits loci (QTLs) associated with body length were identified by interval mapping of the software MapQTL 5.0. A linkage group wide permutation test (1 000 replicates) determined the significance of the maximum LOD value over the various intervals analyzed for each linkage group. Twelve QTLs were identified for body length on the linkage groups of BL-1-1 (SNP0137-SNP1481), BL-4-1 (SNP0092-HLJ797), BL-5-1 (SNP1268-HLJ423), BL-7-1 (HLJ870-SNP0702), BL-12-1 (SNP0922-HLJ639), BL-16-1 (HLJE351-SNP0674), BL-25-1 (SNP0394-SNP0862), BL-35-1 (HLJ668-SNP0832), BL-43-1 (SNP0389-SNP1425), BL-47-1 (HLJ057-HLJ1113), BL-47-2 (HLJ1439-HLJ14180), which explained 13.8% to 64.9% of the total variation of body length. Eight major QTLs explained over 20% of the phenotypic variation, which were major QTLs associated with the body length of mirror carp. Source

Recently, cloud computing rapidly expands as an alternative to conventional computing due to it can provide a flexible, dynamic and resilient infrastructure for both academic and business environments. In public cloud environment, the client moves its data to public cloud server (PCS) and cannot control its remote data. Thus, information security is an important problem in public cloud storage, such as data confidentiality, integrity, and availability. In some cases, the client has no ability to check its remote data possession, such as the client is in prison because of committing crime, on the ocean-going vessel, in the battlefield because of the war, and so on. It has to delegate the remote data possession checking task to some proxy. In this paper, we study proxy provable data possession (PPDP). In public clouds, PPDP is a matter of crucial importance when the client cannot perform the remote data possession checking. We study the PPDP system model, the security model, and the design method. Based on the bilinear pairing technique, we design an efficient PPDP protocol. Through security analysis and performance analysis, our protocol is provable secure and efficient. © 2008-2012 IEEE.
