Ecography, Volume 2026, Issue 3, March 2026.Species diversity typically increases from higher to lower latitudes, but the regional‐scale variation along this geographic gradient remains unclear. It has been suggested that species diversity throughout Amazonia generally increases westward toward the Andes, but this pattern and its environmental determinants require further investigation for most ...

Effect of Subphase Ions on Multilayer Deposition of an Anionic Gemini Surfactant on Solid Substrates
Journal of Surfactants and Detergents, Volume 29, Issue 2, Page 221-231, March 2026.Multilayer formation in Gemini surfactant films with subphase ions. ABSTRACT A recently reported anionic Gemini surfactant belonging to the “minimal linker” family has been shown to form closely packed crystalline monolayers at the air–water interface, like a simple fatty acid, but its ability to deposit onto solid substrates as multilayer films ...

Metric characterizations of some subsets of the real line
Математичні Студії, 2023 A metric space $(X,\mathsf{d})$ is called a {\em subline} if every 3-element subset $T$ of $X$ can be written as $T=\{x,y,z\}$ for some points $x,y,z$ such that $\mathsf{d}(x,z)=\mathsf{d}(x,y)+\mathsf{d}(y,z)$.

Products of $H$-separable spaces in the Laver model
, 2018 We prove that in the Laver model for the consistency of the Borel's conjecture, the product of any two $H$-separable spaces is $M ...

Almost-s-Menger ditopological texture spaces
Hacettepe Journal of Mathematics and Statistics, 2020 The aim of this article is to introduce and characterize almost-s-Menger and almost-co-s-Menger selection properties in ditopological texture spaces. We prove that every s-Menger ditopological texture space is almost-s-Menger and every s-compact ditopological texture space is almost-s-Menger, and give an example which shows that the converse is not ...

Mass Spectrometry Reviews, Volume 45, Issue 2, Page 392-428, March/April 2026.ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

Karpatsʹkì Matematičnì Publìkacìï, 2016 Coupled fixed point problems have attracted much attention in recent times. The aim of this paper is to extend the notions of E.A. property, CLR property and JCLR property for coupled mappings in Menger metric space and use this notions to generalizes ...

Functional-Type Caristi–Kirk Theorem on Menger Space and Application
Journal of Mathematics, 2020 In this paper, we extend Caristi’s fixed point theorem in metric spaces to probabilistic metric spaces, and also, we prove some common fixed point theorems for a pair of mappings satisfying a system of Caristi-type contractions in the setting of a Menger

Shift operators from the simplex representation in momentum-space CFT
Journal of High Energy Physics, 2023 We derive parametric integral representations for the general n-point function of scalar operators in momentum-space conformal field theory. Recently, this was shown to be expressible as a generalised Feynman integral with the topology of an (n − 1 ...
