DETERMINATION OF DOMINANT SEROVARS OF LISTERIA MONOCYTOGENES
Serovars of Lisreria l1Iollocyrogelles were determined. Sera of aborted samples (200) were collected from different hospitals in Tehran and were tested serologically by immunofluorescent antibody methods (IF tests). 137 positive sera were identified. Positive sera were tested against 12 serovars of Listeria l1Iollocytogelles separately. Titers of antibody in patients' sera for all serovars ...
متن کاملMetastability and Dominant Eigenvalues of Transfer Operators
We prove upper and lower bounds for the metastability of a statespace decomposition for reversible Markov processes in terms of dominant eigenvalues and eigenvectors of the corresponding transfer operator. The bounds are explicitly computable and sharp. In contrast to many other approaches, the results do not rely on any asymptotic expansions in terms of some smallness parameter, but rather hol...
متن کاملDetermination of Lamb mode eigenvalues.
An original method is presented to determine the complex Lamb wave spectrum by using a numerical spectral method applied to the elasticity equations. This method presents the advantage to directly determine complex wave numbers for a given frequency via a classical matricial eigenvalue problem, and allows the wave numbers to be determined at relatively high frequencies (i.e., corresponding to m...
متن کاملDetermination of Eigenvalues by Divergent Perturbation Series*
We study eigenvalue problems for operators H0 + tiP', where the per turbat ion series is finite order by order bu t divergent for any ft. We prove that, under suitable conditions, the series nevertheless determines the level uniquely [and is not merely asymptotic] because some control of the remainder term, RN, uni form in N is present; in fact, for fi real, positive, and small, the perturbat i...
متن کاملSmall graphs with exactly two non-negative eigenvalues
Let $G$ be a graph with eigenvalues $lambda_1(G)geqcdotsgeqlambda_n(G)$. In this paper we find all simple graphs $G$ such that $G$ has at most twelve vertices and $G$ has exactly two non-negative eigenvalues. In other words we find all graphs $G$ on $n$ vertices such that $nleq12$ and $lambda_1(G)geq0$, $lambda_2(G)geq0$ and $lambda_3(G)0$, $lambda_2(G)>0$ and $lambda_3(G)
