The Core‐Periphery Model Under Additively Separable Preferences
Journal of Regional Science, Volume 65, Issue 2, Page 378-402, March 2025.ABSTRACT This paper reexamines Krugman's core‐periphery model by substituting his constant elasticity of substitution (CES) utility with a general additively separable utility that comprehensively captures the pro‐competitive effect while preserving the income effect.

Some Properties of Unbounded M-Weakly and Unbounded L-Weakly Compact Operators
, 2023 We introduce the class of unbounded M-weakly compact operators and the class of unbounded L-weakly compact operators. We investigate some properties for this new classification of operators, and we study the relation between them and M-weakly compact and

Psychiatry and Clinical Neurosciences, EarlyView.Aims Obsessive‐compulsive disorder (OCD) is associated with abnormalities in large‐scale brain network dynamics. Conventional electroencephalography (EEG) captures local oscillatory activity but does not characterize spatiotemporal propagation patterns.

Bridging Dimensions in STEAM Education: Linking 2D Function Art and 3D Modeling Using GeoGebra
School Science and Mathematics, EarlyView.ABSTRACT This study examines a constructionist‐oriented STEAM learning activity in which Grade 11 students used GeoGebra 3D to model bridges. Building on prior work in function art, the project extended mathematical art‐making from two‐dimensional representations to three‐dimensional structures, emphasizing the use of functions, geometric ...

A note on the modified Picard integral operators
, 2020 This study is a natural continuation of modified Picard operators, defined by Agratini et al, preserving an exponential function. Herein, we first show that these operators are approximation processes in the setting of large classes of weighted spaces ...

The Journal of Physiology, EarlyView.Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Iterates of a class of discrete linear operators via contraction principle [PDF]
, 2003 summary:In this paper we are concerned with a general class of positive linear operators of discrete type. Based on the results of the weakly Picard operators theory our aim is to study the convergence of the iterates of the defined operators and some ...

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT For complex geometries, the coarse problem of geometric multigrid can be too large to be solved by a direct solver. Here, we report on the use of domain decomposition applied to the multigrid coarse problem. Additive overlapping Schwarz methods are domain decomposition methods for the iterative solution of partial differential equations whose ...

Limitedly L-weakly compact operators [PDF]
, 2023 We introduce new class of limitedly L-weakly compact operators from a Banach space to a Banach lattice. This class is a proper subclass of the Bourgain-Diestel operators and it contains properly the class of L-weakly compact operators.
