In this study we investigate multiply charged ions production from two matrices CHCA and DHB using AP MALDI source coupled to the ion trap Esquire 4400. Based on the published results six main parameters, which influence the charge state of the ions, were identified (Fig 1 below): (1) type...
In order to derive the stress tensor for an infinite lattice, we multiply the rotational invariance, Eq. (5), by the atomic position τϰδ and sum over ϰ. Then, using Eq. (7) we arrive at $${T}_{\alpha \delta ,\beta \gamma }-\Omega {\sigma }_{\gamma \delta }{\delta...
of these matrices. Unlike other Toeplitz+Hankel matri- ces, the Toeplitz+Hankel matrices arising in our context cannot be diagonalized by the discrete cosine transform, but they still allow a fast matrix-vector multiplication via DCT which gives rise to fast conjugate gradient type algorithms. We...
Since the matrices A and B satisfy (1.3), the operator \(L_{A,B}\) is selfadjoint [14]. Obviously, this correspondence between matrices and operators is not one-to-one: one can multiply A and B simultaneously from the left by any invertible matrix, and this defines the same interface...
Multiply (10) by [Math Processing Error] and use commutativity of [Math Processing Error] and [Math Processing Error] to get [Math Processing Error] If we apply A and (8), we find that [Math Processing Error] when [Math Processing Error] is close enough to [Math Processing Error] (...
This has the effect of converting the diffusion region from a simply connected to a multiply connected region. Dirichlet conditions with prescribed flux values zero are imposed on nodes in the interior of the non diffusion zones in order to decouple these nodes from the rest. The method is ...
In that case QA and QA′ have the same sign for A in an open set of nonnegative matrices containing the set of matrices for which R0=1. Consider a matrix such that R0=1. Now concentrate on two arbitrary matrix entries that are not in the same column or row of A, referred to as ...
We prove a two-term asymptotic expansion of eigenvalue sums of the Laplacian on a bounded domain with Neumann, or more generally, Robin boundary conditions. We formulate and prove the asymptotics in terms of semi-classical analysis. In this reformulation it is natural to allow the function descr...

Summer rain allows summer active adults to multiply immediately. For instance, Z. moralesi reproduced, developed, and metamorphosed in 75 days or less [52]. It is, therefore, possible to recruit a fresh cohort of adults within the same annual breeding season and increase the irruption. ...
