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.

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

Some remarks on measures of noncompactness and retractions onto spheres
, 2007 Some ways to obtain upper and lower bounds for measures of noncompactness of retractions onto spheres in infinite-dimensional normed spaces are discussed. Moreover, relations with 0-epi maps are revealed and the extension of condensing maps on spheres is

Hausdorff measure of noncompactness in some sequence spaces of a triple band matrix [PDF]
, 2013 The sequence spaces c(0)(B), l(infinity)(B) have recently been introduced by Somez (Comput. Math. Appl. 62: 641-650, 2011). In this paper, we establish some identities or estimates for the operator norms and the Hausdorff measures of noncompactness of ...

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 ...

On the bounded compact approximation property and measures of noncompactness
, 1987 The Banach spaces with the bounded compact approximation property are characterized by the completeness of measures of noncompactness. Applications to the theory of semi-Fredholm operators and to the algebraic properties of their canonical images in the ...

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 ...

Measures of noncompactness and upper semi-Fredholm perturbation theorems
, 1993 We introduce the concept of a perturbation function, which allows us to give a general approach to the question of obtaining perturbation theorems for upper semi-Fredholm operators.
