Fat equator effect and minimality in immersions and submersions of the sphere

open access: yesTransactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.
Abstract Inspired by the equatorial concentration of measure phenomenon in the sphere, a result which is deduced from the general (and intrinsic), concentration of measure in Sn(1)$\mathbb {S}^n(1)$, we describe in this paper an equatorial concentration of measure satisfied by the closed (compact without boundary), isometric and minimal immersions x:Σm→

Sustainable control of Dalbulus maidis: A field study with entomopathogenic fungi

open access: yesEntomologia Experimentalis et Applicata, Volume 173, Issue 11, Page 1156-1164, November 2025.
Dalbulus maidis, a plant pathogen vector, poses a serious threat to maize production and food security. We investigated the potential synergistic effects between formulations based on entomopathogenic fungi and corn hybrids with varying resistance to maize stunt complex and Maize rayado fino virus. The combined management of M. anisopliae + B. bassiana

Mismanagement amid resource abundance: Sovereign risk, private sector credit rationing, and economic stagnation in Colombia, 1861‒98

open access: yesThe Economic History Review, Volume 78, Issue 4, Page 1118-1150, November 2025.
Abstract This article examines the relationship between national politics, sovereign default, credit rationing, and their effects on fiscal revenues and exports in nineteenth‐century Colombia. Using quantitative and qualitative analysis, it challenges existing narratives on Colombia's lack of sustained nineteenth‐century export‐led development, showing
