Research On Collaborative Filtering Recommendation Algorithm Based On Temporal Behavior
Yuanzhen Liu1, 2,Jianzhao Liu1
Collaborative filtering directly predicts the products that may be liked by the user's behavior records, it is the most successful and widely used method of recommendation. Probabilistic matrix factorization is one of the most important collaborative filtering methods. It is recommended by learning the approximate matrix of low dimension, and can effectively deal with massive data. However, the traditional probabilistic matrix factorization method often ignores the relationship between users and products, and affects the effect of recommendation algorithms. By measuring the relationship between users to find similar neighbor users, we can more accurately identify the user's personal interests, so as to effectively improve the accuracy of collaborative filtering recommendation. To solve this problem, a method for modeling temporal behavior among users is proposed. Based on this method, the neighbor set which has the greatest influence on the current user can be found. Furthermore, the neighbor set is successfully fused into a collaborative filtering recommendation algorithm based on probabilistic matrix decomposition.

Epids: Imprecise D-s Inference Models For Detection Of Epistatic Snp-snp Interactions
Yaling Yin, Junying Zhang
The study of epistatic SNP-SNP interactions is a powerful way for revealing the causes of common complex diseases. However, the testing of a large number of SNP-SNP interactions presents a large statistical and computational burden. Several methods have been developed for analysis of certainty statistical interaction models in case-control studies. As far as uncertainty interaction models, however, few methods currently exist to deal with the immense search space. We have developed a new approach – epistatic difference D-S inference (EpiDS)–that uses inferential models to detect epistasis while handling uncertainty separately. EpiDS combines the D-S evidence of the inference model framework on the basis of random forest filtration. In simulated data sets, epistatic interactions are accurately discovered. In applying a real data set of age-related macular degeneration (AMD), the results show that EpiDS highlights the certainty and decreases the uncertainty of disease models. EpiDS is able to detect SNPs related to AMD, as well as those that suppress the disease, including rs1923438 in the gene PTPRT. These experimental results demonstrate that the proposed identification method for detection of epistasis represents an effective and novel technique for identifying the uncertainty in disease models.

Design Method Of Meridional Contours Based On Velocity Distribution Of Multi-stage Composite Impeller
Jiangfeng Fu, Huacong Li, Xianwei Liu, Jiaxing Zhu, Jing Liu
The aim of this paper was to solve the integrated design problem of meridional contours of the multi-stage composite impeller centrifugal pump with special structure. A design method of axial flow channel is proposed based on the rule of axial velocity distribution. The cubic spline curve was used to fit the shroud and hub to get the central axis of the meridional contours. Then the meridional velocity distribution was analysed combined with the result of numerical simulation after obtaining the variation of the cross-flow section area. Finally, adapting the dimensionless method to establish the constraints model that used in the design differential equations according to medial axis theory to draw the appropriate meridional contours. Research results show that the cross-flow section area of this type of impeller is not linear or parabolic distribution which is different from existing theory. Crowding-out effect is the main reason of the error in meridional velocity calculation. The proposed design method is easy to control the shape of the axial flow channel. The variation trend of the flow area and axial surface velocity designed by this method is well fitted with the impeller of the model pump. This method has good engineering practical value in the design of centrifugal pumps.

Weida Zhan, Yijun Wang,ziqiang Hao
Routing algorithms for HWOBAN have such problems as greater time delay, lower delivery ratio and lower throughput than the state of art wireless networks do. Context-Aware Cross-Layer routing algorithm is presented to work out corresponding issues. Firstly, we inserted neighbour ID code into IEEE 802.3 frame that included neighbour ID option and relationship option. Before sending packets, an OLT firstly considered its neighbour OLTs according to link cost, and then selected an appropriate OLT as next-hop node. Secondly, we reallocated wireless routers roles according to their state for packets transmission. After reallocation, the wireless router compared neighbourhood based on context, and then chosen effective neighbour link for information transmission. Simulation experiments show that this algorithm achieves shorter time delay and higher packets delivery ratio. The algorithm also increases network throughput compared with other algorithms.

Actin Cytoskeleton Regulators Required For Cell Migration In Drosophila Ovary
Ping Wan, Sumei Zheng
Cell migration is prevalent in many physiological and pathological processes. Some cells migrate as single cell, but many cell types migrate collectively in loosely or closely associated cell groups. Molecular mechanisms of single cell migration have been well studied, however study of the mechanisms of collective cell migration is limited. Border cell migration in Drosophila ovary has shown be a good in vivo model to study collective cell migration and identify genes involved in regulating this process. Actin cytoskeleton is an essential modulator of cell motility and is precisely controlled during the migration process. In this study, we focus on regulators of actin cytoskeleton. By driving expression of 23 RNAi lines specifically in border cells, we knocked down 12 genes encoding actin binding proteins to identify whether they are essential for border cell migration. Expressions of most RNAi lines in border cells cause migration defects. Knocking down 4 of the 12 genes causes more severe migration defects compared with other genes and the control. Our data suggest that these 4 genes are important for border cell migration.

Abstract: The calculation method of cutting force of a single tooth for slicing tool of cycloid gear based on micro-section edge was proposed. Machining the tooth flank directly from blank by continuous indexing, gear slicing can dramatically improve the efficiency. We set up the model based on the characteristics that relevant parameters with cutting are time-varying during the cutting process such as the edges involved cutting, the cutting speeds of arbitrary points on cutting edges and the thickness of cutting layer etc. The cutting edge is divided into three sections: cut-in edge, top edge and cut-out edge, and then the cutting force for each of them can be calculated. When analyzing the cutting force, we proposed the concept of micro-section edge, where the three component forces on x, y and z directions are calculated by the calculation method of bevel cutting force. First calculating cutting force generated by each of the three sections and then the resultant formed by three component forces, which is the cutting force of a single tooth. The theory meets the urgent demand of calculation method for cutting force of slicing cutter, promotes the designing process for tool and machine of gear slicing and lays the foundation to develop more accurate calculation method for cutting force of gear slicing.

The acquisition of pulse signal is mainly obtained by the weak signal amplification. In this process, the noise of the circuit coupling will seriously affect the characteristic analysis of the signal. Focus on noise interference in the process of PPG signal acquisition a denoising algorithm based on Bayesian wavelet analysis is proposed. On the basis of wavelet analysis of PPG signal, the optimal wavelet coefficient threshold and weighting factor are calculated through Bayesian algorithm, and finally realized the denoising and reconstruction of PPG signal. The experimental results show that the proposed algorithm can eliminate the noise of PPG signal and reduce the distortion of the signal. Compared with wavelet soft threshold and hard threshold algorithms, the calculation shows that the MSE of the algorithm is 0.0067 and PSNR is 69.8991, which is superior to the two algorithms, and has high use value.
