摘要：
In this paper, we consider a mathematical model for HIV-1 infection with intracellular delay and cell-mediated immune response. A novel feature is that both cytotoxic T lymphocytes (CTLs) and the intracellular delay are incorporated into the model. We obtain a necessary and sufficient condition for the global stability of the infection-free equilibrium and give sufficient conditions for the local stability of the two infection equilibria: one without CTLs being activated and the other with. We also perform some numerical simulations which support the obtained theoretical results. These results show that larger intracellular delay may help eradicate the virus, while the activation of CTLs can only help reduce the virus load and increase the healthy CD(4)(+) cells population in the long term sense.
摘要：
Based on the ideal solution approximation, the model for size-dependent melting temperature of pure metal nanoparticles is extended to binary alloy systems. The developed model, free of any adjustable parameter, demonstrates that the melting temperature is related to the size and composition of alloy nanoparticles. The melting temperature of CuNi, PbBi and SnIn binary alloy nanocrystals is found to be consistent with the experiments and molecular dynamics simulations. The research reveals that alloy nanocrystals have similar melting nature as pure metal.

摘要：
The maximal clique problem is an NP (nondeterministic polynomial time)-complete problem. We present an algorithm that solves maximal clique problem within the framework of a surface-based model of computation. The time complexity of our algorithm is O(n2), and the number of kinds of short oligonucleotides needed to encode maximal clique problem is n + 3, where n is the size of the graph. In our algorithm, immobilizing DNA (deoxyribonucleic acid) strands to a solid surface reduces the possibility of error resulting from the loss of DNA strands in solution. A solution-based algorithm solving maximal clique problem has previously been proposed by Qi Ouyang et al.. In their algorithm, the number of enzyme is equal to the number of vertices of the graph, which causes the difficulty of encoding and scaling up, because the DNA sequences of restriction enzyme sites should not be present in otherwhere. Using surface-based model, we designed an algorithm for maximal clique problem, which needs only one enzyme.

摘要：
In this paper, we are concerned with the fast solvers for higher order edge finite element discretizations of Maxwell’s equations. We present the preconditioners for the first family and second family of higher order Nédélec element equations, respectively. By combining the stable decompositions of two kinds of edge finite element spaces with the abstract theory of auxiliary space preconditioning, we prove that the corresponding condition numbers of our preconditioners are uniformly bounded on quasi-uniform grids. We also present some numerical experiments to demonstrate the theoretical results.

ductile/brittle substrates;representative strain;finite element method (FEM);forward/reverse analysis
摘要：
A new approach to extract the mechanical properties of ductile thin films on brittle substrates based on the representative strain (corresponding to the representative stress) has been presented in depth-sensing indentation with finite element method (FEM). Forward and reverse analyses of high deformation symmetry numerical simulation of Berkovich indentation tests are used to determine mechanical properties of ductile films. The proposed reverse analysis provides a new solution for the initial yield stress (or the representative stress) and the strain-hardening exponent, given that the Young's modulus is predetermined from the Sakai method, e.g., as [1]. The validity of the reverse analysis method is checked using the numerical nano-indentation test.

摘要：
We research the model for the Ebola outbreak, such as the spread of the disease, the quantity of the medicine needed, possible feasible delivery systems, locations of delivery and the speed of manufacturing of the vaccine or drug. In order to describe the spread of the Ebola virus, we have established a model for the Delay Differential Equations with latency parameter, using the numerical calculation and analysis, the spread of the Ebola virus are described. We found the model to stop the spreed of the virus according to the number of infections, which is connected with the time variable. People are encouraged to cooperate with the government prevention and treatment by the classification isolation and buffer isolation. In order to find the best solution to control the epidemic, examining the Ebola epidemic in Africa and using the shortest path of Floyd-War shall algorithm from the classical location problem, we carefully selected three drug distribution centers. We establish the optimization model of graph theory under an insufficient supply, which make a minimum transportation costs and control the epidemic, according to the location of drug delivery, drug, vaccine production speed and the demand for drug, when drugs were in short supply, we constructed function with correction factor, we converted into a situation to solve the problem under an adequate supply of medicines

Steel high strength concrete column;seismic performance;axial compression ratio;stirrup ratio;steel ratio;finite element analysis
摘要：
In the thesis, simulated analysis of eight steel reinforced high strength concrete column under the low reversed cyclic horizontal load were performed by using the nonlinear finite element software of ABAQUS. The hysteresis behavior, skeleton curve, displacement ductility energy-dissipating capacity of the steel reinforced concrete column under the combined action of the bending, pressing, and shearing were discussed in this thesis. And it also analyzed factors that affect the bearing capacity and ductility of the steel reinforced column, such as axial compression ratio, stirrup ratio, steel ratio. Results indicate that the displacement ductility factor between 2.43 and 3.95; The stirrup ratio have a greater impact on the seismic performance of steel reinforced high strength concrete columns. With the increment of volume-stirrup ratio and steel ratio, the ductility factor increases; As The axial compression ratio increased, bearing capacity increased correspondingly; When steel reinforced concrete column are under higher axial pressure, stirrup ratio has more significant effect on the bearing capacity of structure.

摘要：
In this study, we propose a manifold learning-based method for predicting disease genes by assuming that a disease and its associated genes should be consistent in some lower dimensional manifold. The 10-fold cross-validation experiments show that the area under of the receiver operating characteristic (ROC) curve (AUC) generated by our approach is 0.7452 with high-quality gene-disease associations in OMIM dataset, which is greater that of the competing method PBCF (0.5700). 9 out of top 10 predicted gene-disease associations can be supported by existing literature, which is better than the result (6 out of top 10 predicted association) of the PBCF. All these results illustrate that our method outperforms the competing method.

fuzzy multiple objectives decision making;vague sets;objective decision making matrix
摘要：
As a further generalization of fuzzy set theory, the vague set theory can overcome the shortcomings of fuzzy set by describing the membership from two sides of both TRUE and FALSE, rather than only by a single membership value. Since vague sets can provide more information than fuzzy sets, it is superior in mathematical analysis of system with uncertainty. In this paper, a new method vague set-based is proposed to deal with fuzzy decision fusion problem. Compared with traditional fuzzy decision fusion method-such as fuzzy comprehensive evaluation, the new method is more efficient and powerful to fulfill decision fusion with uncertain and inaccurate information. Generally, the new method is the same with group decision fusion and soft fusion.

摘要：
It is because the matrix arrangement cement lining steel shear which have large elastic-plsatic deformation, yield deformation and slip body, as well as existing multiple complex nonlinear and coupling that traditional methods have not been able to meet the analysis requirements. Therefore, The coupled theory based on elastic mechanics, fracture mechanics and brittle fracture was put forward by considering the change" elastic deformation-plastic yield-shear fracture", and having in-depth discussion about the sheear process. Eventually, a complete mathematical model of matrix arrangement cement lining steel shear has been formed to provides theoretical basis for shear performance and mechanics analysis.
