ON A NEW CLASS OF MULTIVALUED WEAKLY PICARD OPERATORS ON COMPLETE METRIC SPACES
Taiwanese Journal of Mathematics, 2015 In the present paper, the concept of nonlinear $F$-contraction formultivalued mappings in metric spaces is introduced and considering the new proof technique, which was used for single valued maps by Wardowski [D. Wardowski, Fixed points of a new type of contractive mappings in complete metric spaces, Fixed Point Theory Appl.

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.

The Theory of Reich's Fixed Point Theorem for Multivalued Operators
Fixed Point Theory and Applications, 2010 The purpose of this paper is to present a theory of Reich's fixed point theorem for multivalued operators in terms of fixed points, strict fixed points, multivalued weakly Picard operators, multivalued Picard operators, data dependence of the fixed ...

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, EarlyView.Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

Well-posedness via Monotonicity. An Overview
, 2014 The idea of monotonicity (or positive-definiteness in the linear case) is shown to be the central theme of the solution theories associated with problems of mathematical physics.

Plant Biotechnology Journal, EarlyView.ABSTRACT As the staple food of over half the world's population, rice with a high resistant starch (RS) content may be beneficial in the dietary prevention of diabetes and hyperlipidemia. Mutating key enzymes in starch metabolism to increase the RS content has been successful in other crops.

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.

Role of Septin7 in mitochondrial dynamics and oxidative metabolism in C2C12 skeletal muscle cells
The Journal of Physiology, EarlyView.Abstract figure legend Knockdown of Septin7 alters the expression of markers responsible for mitochondrial dynamics. Members of the electron transport chain are also affected by diminished Septin7 level resulting in functional changes of mitochondrial respiration. Abstract Mitochondria are dynamic organelles that undergo fusion and fission.

The Journal of Creative Behavior, Volume 60, Issue 1, March 2026.ABSTRACT Cognitive control is known to support divergent thinking in adults, but findings in children remain mixed. This study examined the association between cognitive control—measured as a composite score from two executive function tasks—and verbal divergent thinking in 120 French‐speaking school‐aged children (aged 10 to 12 years). Originality and
