Providing regular and frequent maps of losses and gains of farmland birds based on European monitoring data

open access: yesConservation Biology, EarlyView.
Abstract Knowledge of species distributions is essential for informing policies on nature conservation and restoration. However, updating them on a regular basis and doing so in a harmonized manner at the international level is difficult. The European Bird Census Council integrated national monitoring data covering 5 years to update farmland bird ...

On an interpolation problem on a class of a radially weighted harmonic Bergman space

open access: yesJournal of Inequalities and Applications
The purpose of the present article is to interpolate a sequence by a function in the space of a weighted harmonic Bergman space on the unit ball such that the weight is provided radially.

3-Complex Symmetric and Complex Normal Weighted Composition Operators on the Weighted Bergman Spaces of the Half-Plane

open access: yesMathematics
One of the aims of this paper is to characterize 3-complex symmetric weighted composition operators induced by three types of symbols on the weighted Bergman space of the right half-plane with the conjugation Jf(z)=f(z¯)¯.

Commuting Quasihomogeneous Toeplitz Operator and Hankel Operator on Weighted Bergman Space

open access: yesAbstract and Applied Analysis, 2013
We characterize the commuting Toeplitz operator and Hankel operator with quasihomogeneous symbols. Also, we use it to show the necessary and sufficient conditions for commuting Toeplitz operator and Hankel operator with ordinary functions.

A matheuristic for the traveling salesman problem with positional consistency constraints

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract We propose a matheuristic for the traveling salesman problem with positional consistency constraints, where we seek to generate a set of routes with minimum total cost, in which the nodes visited in more than one route (consistent nodes) must occupy the same relative position in all routes.

Toeplitz Operators on the Weighted Pluriharmonic Bergman Space with Radial Symbols

open access: yesAbstract and Applied Analysis, 2011
We construct an operator R whose restriction onto weighted pluriharmonic Bergman Space bμ2(Bn) is an isometric isomorphism between bμ2(Bn) and l2#. Furthermore, using the operator R we prove that each Toeplitz operator Ta with radial symbols is unitary ...

Future Life Plans and Relationship Formation: A Bidirectional Approach Based on Evidence From Finland

open access: yesJournal of Marriage and Family, EarlyView.
ABSTRACT Objective This study examines the prospective and bidirectional association between personal identity processes and relationship formation using longitudinal survey data from Finland. Background Although psychological factors have increasingly been studied as determinants for family formation processes, the role of identity exploration and ...
