Male partners' involvement is a vital issue to prevent human immunodeficiency virus (HIV) transmission from mother to child; because it is much expectable that women were more vulnerable and high risk group of population portion. Therefore, to save lives of mothers and their newborn from acquiring HIV, male partners should do their maximum endeavor regardless of any determinant factors as our r...

We verify a conjecture of Gillet-Soulé. We prove that the determinant of the Laplacian on a line bundle over CP is always bounded from above. This can also be viewed as a multi-particle generalization of the Moser-Trudinger Inequality. Furthermore, we conjecture that this functional achieves its maximum at the canonical metric. We give some evidence for this conjecture, as well as links to othe...

This paper presents an optimal planning problem for workpiece measurement. Two sequential optimization algorithms are introduced to find maximum determinant solutions. Then, based on a reliability analysis of workpiece localization and the sequential optimization algorithms, a computer-aided probing strategy is proposed. With this strategy, given the desired translation and orientation error bo...

We consider a new nonlinear relaxation for the Constrained Maximum Entropy Sampling Problem { the problem of choosing the s s principal submatrix with maximal determinant from a given n n positive deenite matrix, subject to linear constraints. We implement a branch-and-bound algorithm for the problem, using the new relaxation. The performance on test problems is far superior to a previous imple...

We study multivariate normal models that are described by linear constraints on the inverse of the covariance matrix. Maximum likelihood estimation for such models leads to the problem of maximizing the determinant function over a spectrahedron, and to the problem of characterizing the image of the positive definite cone under an arbitrary linear projection. These problems at the interface of s...

The class of square matrices order n having a negative determinant and all their minors up to n−1 nonnegative is considered. A characterization these presented which provides an easy test based on the Cauchon algorithm for recognition. Furthermore, maximum allowable perturbation entry in position (2,2) such that perturbed matrix remains this given. Finally, it shown lying between two with respe...

in this research, the effect of entomopathogenic fungus, beauveria bassiana (ascomycota, hypocreales), on functional response (in laboratory) and reproduction (in microcosm) of parasitoid wasp, aphidius matricariae haliday (hym.: braconidae) on its host, myzus persicae (sulzer) (hem.: aphididae) was investigated. illustrating number of mummified aphids versus initial density of green peach aphi...

conclusions results of the present study showed that the tst and sea genes had high frequencies among the mrsa isolates. the increased prevalence of mrsa isolates containing different virulence genes, probably accompanied by antimicrobial resistance, can complicate the therapy of mrsa isolates. results all the tested isolates were susceptible to vancomycin, but resistant to penicillin (100%), e...
