Quincunx Fundamental Refinable Functions in Arbitrary Dimensions
Axioms, 2017 In this paper, we generalize the family of Deslauriers–Dubuc’s interpolatory masks from dimension one to arbitrary dimensions with respect to the quincunx dilation matrices, thereby providing a family of quincunx fundamental refinable functions in ...

Symmetric multivariate orthogonal refinable functions [PDF]
, 2004 In this paper, we shall investigate the symmetry property of a multivariate orthogonal M-refinable function with a general dilation matrix M. For an orthogonal M-refinable function ϕ such that ϕ is symmetric about a point (centro-symmetric) and ϕ ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Fractional GP refinable functions [PDF]
, 2007 A new class of refinable functions extending the GP class introduced in [12] is presented. It is characterized by a symbol with fractional exponent that gives rise to non-compactly supported refinable functions.

Refinable Functions with PV Dilations [PDF]
, 2017 A PV number is an algebraic integer $α$ of degree $d \geq 2$ all of whose Galois conjugates other than itself have modulus less than $1$. Erdös \cite{erdos} proved that the Fourier transform $\widehat φ,$ of a nonzero compactly supported scalar valued function satisfying the refinement equation $φ(x) = \frac{|α|}{2}φ(αx) + \frac{|α|}{2}φ(αx-1)$ with ...

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations
Pediatric Blood &Cancer, EarlyView.ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.

Piecewise-smooth refinable functions
, 2005 Univariate piecewise-smooth refinable functions (i.e., compactly supported solutions of the equation (formula presented) are classified completely. Characterization of the structure of refinable splines leads to a simple convergence criterion for the ...

Totally positive refinable functions with general dilation M [PDF]
, 2017 We construct a new class of approximating functions that are M-refinable and provide shape preserving approximations. The refinable functions in the class are smooth, compactly supported, centrally symmetric and totally positive.

Refinements of the Lower Bounds of the Jensen Functional [PDF]
Abstract and Applied Analysis, 2011 The lower bounds of the functional defined as the difference of the right‐hand and the left‐hand side of the Jensen inequality are studied. Refinements of some previously known results are given by applying results from the theory of majorization. Furthermore, some interesting special cases are considered.
