Independent vector analysis (IVA) is a new method for solving the permutation problem in the frequencydomain independent component analysis. IVA assumes inner dependency among the frequency components of each source; then, it treats a set of the frequency components of a source as a source vector. Although the effectiveness of IVA has been demonstrated by its applications, there are very few ma...

in this paper, load and buckling mode of a smart column are presented. the theoretical model is a three-layer piezoelectric composite beam that behaves as an axial actuating mechanism. this actuator consists of an elastic core sandwiched between two piezoelectric active outer layers. the piezoelectric layers are polarized transversely, i.e., the polarization vector is parallel to the applied el...

background: hepatitis c virus (hcv) infection is one of the most prevalent infectious diseases responsible for high morbidity and mortality worldwide. therefore, designing new and effective therapeutics is of great importance. the aim of the current study was to construct a dna vaccine containing structural proteins of hcv and evaluation of its expression in a eukaryotic system. methods: struct...

 We consider the problem of model selection in vector autoregressive model with Normal innovation. Tests such as Vuong's and Cox's tests are provided for order and model selection, i.e. for selecting the order and a suitable subset of regressors, in vector autoregressive model. We propose a test as a modified log-likelihood ratio test for selecting subsets of regressors. The Europe oil prices, ...

In this paper, we study the classical sensitivity analysis when the right - hand – side vector, and the coefficients of the objective function are allowed to vary. 

background: cholera toxin b subunit (ctb) has been extensively considered as an immunogenic and adjuvant protein, but its yield of expression is not satisfactory in many studies. the aim of this study was to compare the expression of native and mutant recombinant ctb (rctb) in pqe vector. methods: ctxb fragment from vibrio cholerae o1 atcc14035 containing the substitution of mutant ctxb for ami...

objective: the aim of this study was to construct a pcdna3.1+ vector containing fmdv type o/irn/1/2007-vp1 gene, protein expression in bhkt7 cells and evaluation of immune response in balb/c mice. materials and methods: fmdv type o/irn/1/2007 was isolated from a cattle in ray in 2007 and serotyped. the purified vp1 gene was sub-cloned into the ptz57r/t vector and pcdna3.1+ expression vector. t...
