On modulus of noncompact convexity for a strictly minimalizable measure of noncompactness

Gulf Journal of Mathematics, 2014
In this paper we consider modulus of noncompact convexity ΔX,φ associated with the strictly minimalizable measure of noncompactness φ. We also give some its properties and show its continuity on the interval [0, φ(BX)).

The systole of random hyperbolic 3‐manifolds

Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.
Abstract We study the systole of a model of random hyperbolic 3‐manifolds introduced in Petri and Raimbault [Comment. Math. Helv. 97 (2022), no. 4, 729–768], answering a question posed in that same article. These are compact manifolds with boundary constructed by randomly gluing truncated tetrahedra along their faces.

Impulsive fractional differential equations in Banach spaces

Electronic Journal of Qualitative Theory of Differential Equations, 2009
This paper is devoted to study the existence of solutions for a class of initial value problems for impulsive fractional differential equations involving the Caputo fractional derivative in a Banach space. The arguments are based upon Mönch's fixed point

Hausdorff Measures of Noncompactness and Interpolation Spaces [PDF]

, 2006
2000 Mathematics Subject Classification: 46B50, 46B70, 46G12.A new measure of noncompactness on Banach spaces is defined from the Hausdorff measure of noncompactness, giving a quantitative version of a classical result by R. S. Phillips.

Experimental investigations and design of precast concrete‐filled steel corrugated sheet slender columns with intermediate connection

Structural Concrete, Volume 27, Issue 1, Page 193-210, February 2026.
Abstract Concrete‐filled steel corrugated sheet (CFSCS) offers confinement to the core concrete while the outer galvanized corrugated steel sheet (GCSS) offers excellent corrosion resistance. Application of precast multiple CFSCS columns connected through high‐performance concrete (HPC) in constructing a slender column offers ease of construction while

Solvability of integral equations via the technique of measures of noncompactness

Miskolc Mathematical Notes
Motivated by the work of [Mohammadi et al., Mathematics, 2019, 7, 575.], we extend here Darbo’s fixed point theorem in a Banach space using the combined technique of Wardowski-Mizoguchi-Takahashi contraction.

Plastic Behavior and Design Methodology for Curved Members in Seismic Applications

JAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.
This study investigated the plastic behavior of curved members through static analysis and extensive parametric studies, focusing on initial elastic stiffness, plastic strength, slenderness effects, and section compactness. Estimation equations were developed and validated, contributing to the development of a connection design methodology that ...
