Computing planar and spherical choreographies [PDF]
, 2015 An algorithm is presented for numerical computation of choreographies in the plane in a Newtonian potential and on the sphere in a cotangent potential. It is based on stereographic projection, approximation by trigonometric polynomials, and quasi-Newton ...

, 2003 We take a unifying and new approach toward polynomial and trigonometric approximation in an arbitrary number of variables, resulting in a precise and general ready-to-use tool that anyone can easily apply in new situations of interest. The key idea is to

Archaeological Prospection, EarlyView.ABSTRACT Neolithic long barrows are among the earliest monumental structures in Europe, yet in many parts of Central Europe their surface expression has been largely erased by long‐term agricultural activity. This study evaluates the potential of integrated remote sensing approaches for identifying and contextualizing long barrows and associated ...

On Weighted Lp Integrability of Functions Defined by Trigonometric Series
Journal of Inequalities and Applications, 2010 We introduce a new class of sequences called GM¯θr and give a sufficient and necessary condition for weighted Lp integrability of trigonometric series with coefficients to belong to the above class.

A Novel 3D Wiring Technique—ZOLUTION Zero Degree OverLap View Universal Three DimensIONal CTO Wiring
Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT We present a novel simple and easy‐to‐use 3D wiring technique for coronary chronic total occlusions (CTOs) named ZOLUTION—Zero OverLap View Universal Three dimensIONal wiring. ZOLUTION can be used for: (1) Distal cap puncture, (2) CTO body wiring, (3) Retrograde wiring, and (4) Reverse controlled antegrade and retrograde tracking (reverse CART)

Approximation of classes B^ω_p,θ of periodic functions of several variables by polynomials with spectrum from cubic areas (in Ukrainian) [PDF]
Математичні Студії, 2011 We have obtained exact order estimates for error of approximation of classes B^ω_p,θ of periodic functions of several variables by trigonometric polynomials with spectrum from cubic areas.

Fast O(1) bilateral filtering using trigonometric range kernels [PDF]
, 2011 It is well-known that spatial averaging can be realized (in space or frequency domain) using algorithms whose complexity does not depend on the size or shape of the filter.

Asymmetric Feature Maps with Application to Sketch Based Retrieval
, 2017 We propose a novel concept of asymmetric feature maps (AFM), which allows to evaluate multiple kernels between a query and database entries without increasing the memory requirements.

Communications on Pure and Applied Mathematics, EarlyView.ABSTRACT The leading‐order asymptotic behavior of the solution of the Cauchy initial‐value problem for the Benjamin–Ono equation in L2(R)$L^2(\mathbb {R})$ is obtained explicitly for generic rational initial data u0$u_0$. An explicit asymptotic wave profile uZD(t,x;ε)$u^\mathrm{ZD}(t,x;\epsilon)$ is given, in terms of the branches of the multivalued ...
