Based on previously developed Mode Pursuing Sampling (MPS) approach for continuous variables, a variation of MPS for discrete variable global optimization problems on expensive black-box functions is developed in this paper. The proposed method, namely, the discrete variable MPS (D-MPS) method, differs from its continuous variable version not only on sampling in a discrete space, but moreover, ...

In this paper, we develop a method to count the number of spanning trees in certain classes of double fixed-step loop networks with nonconstant steps. More specifically our technique finds the number of spanning trees in ~ C n , the double fixed-step loop network with n vertices and jumps of size p and q, when n = d1m, and q = d2m+ p where d1, d2, p are arbitrary parameters and m is a variable.

A new version of the time-dependent close-coupling method is used to calculate the single and double photoionization of the Be and Mg atoms. Total cross sections are calculated using an implicit time propagator with a core orthogonalization method on a variable radial mesh. The double to single photoionization cross section ratios are found to be in good agreement with experiment for both Be an...

A double transformation kernel density estimator that is suitable for heavy-tailed distributions is presented. Using a double transformation, an asymptotically optimal bandwidth parameter can be calculated when minimizing the expression of the asymptotic mean integrated squared error of the transformed variable. Simulation results are presented showing that this approach performs better than ex...

Abstract We prove local $C^{0,\alpha }$- and $C^{1,\alpha }$-regularity for the solution to an obstacle problem with nonstandard growth. These results cover as special cases standard, variable exponent, double phase, Orlicz

In this paper we establish square-function estimates on the double and single layer potentials with rough inputs for divergence form elliptic operators, of arbitrary even order 2m, with variable t-independent coefficients in the upper half-space.

This work concerns how to find the double periodic form of approximate solutions of the perturbed combined KdV (CKdV) equation with variable coefficients by using the homotopic mapping method. The obtained solutions may degenerate into the approximate solutions of hyperbolic function form and the approximate solutions of trigonometric function form in the limit cases. Moreover, the first order ...

Targeting of AID to antibody variable (V) regions results in somatic hypermutation, whereas its recruitment to switch (S) regions leads to class-switch recombination. Yeap et al. find that the mechanism by which variable and switch regions recruit AID essentially is the same but that the two regions differ in the density of double-stranded DNA breaks that are generated. These lead to either poi...

In this paper, a nonlinear acoustic echo cancellation (AEC) system is proposed, whereby 3rd order Volterra filtering is utilized along with a variable step-size Gauss-Seidel pseudo affine projection (VSSGS-PAP) algorithm. In particular, the proposed nonlinear AEC system is developed by considering a double-talk situation with near-end signal variation. Simulation results demonstrate that the pr...

congenital double lip anomaly is an infrequent developmental abnormality affecting the lips, more commonly the upper lip. 5 cases of double lip are being reported for the first time from iran and all confined to the upper lip. a new surgical excision is being introduced which is called transverse cupid bow-like elliptical incision. the previous traditional method was a simple elliptical excisio...
