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.

Measures of noncompactness on the standard hilbert C*-module
Filomat, 2019 We define a measure of noncompactness ? on the standard Hilbert C*-module l2(A) over a unital C*-algebra, such that ?(E) = 0 if and only if E is A-precompact (i.e. it is ?-close to a finitely generated projective submodule for any ? > 0) and derive its properties.

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

Nonlinear Integrodifferential Equations of Mixed Type in Banach Spaces
International Journal of Mathematics and Mathematical Sciences, 2007 We prove two existence theorems for the integrodifferential equation of mixed type: x'(t)=f(t,x(t),∫0tk1(t,s)g(s,x(s))ds,∫0ak2(t,s)h(s,x(s))ds), x(0)=x0, where in the first part of this paper f, g, h, x are functions with values in a Banach space E and ...

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 ...

Caught Between the Brain and a Hard Place: A Case of a Cervicomedullary AVM
Case Reports in Radiology, Volume 2026, Issue 1, 2026.Posterior fossa arteriovenous malformations (AVMs) are uncommon lesions that carry significant risk due to their proximity to the brainstem. We present the case of an 18‐year‐old female who suffered a sudden severe headache and was found to have a subarachnoid haemorrhage caused by a cervicomedullary junction AVM of the juvenile Type IIa subtype ...

Solvability of second order linear differential equations in the sequence space n(ϕ) $n(\phi)$
Advances in Difference Equations, 2018 We apply the concept of measure of noncompactness to study the existence of solution of second order differential equations with initial conditions in the sequence space n(ϕ) $n(\phi)$.
