Some new directions in infinite-combinatorial topology
, 2006 We give a light introduction to selection principles in topology, a young subfield of infinite-combinatorial topology. Emphasis is put on the modern approach to the problems it deals with. Recent results are described, and open problems are stated.

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 ...

Nearly Menger covering property via bitopological spaces
AIMS Mathematics<p>This paper is a continuation and complement for previous works on selective covering properties. We introduce the novel concept of the nearly Menger property in a bitopological context. We demonstrate its interrelations with existing covering properties and construct certain equivalences between those. We also investigate various properties of

Combinatorial images of sets of reals and semifilter trichotomy
, 2010 Using a dictionary translating a variety of classical and modern covering properties into combinatorial properties of continuous images, we get a simple way to understand the interrelations between these properties in ZFC and in the realm of the ...

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

Menger curvature and rectifiability
, 1999 For a Borel set E in R^n, the total Menger curvature of E, or c(E), is the integral over E^3 (with respect to 1-dimensional Hausdorff measure in each factor of E) of c(x,y,z)^2, where 1/c(x,y,z) is the radius of the circle passing through three points x,

Extracorporeal photopheresis—New insights into an old procedure
Transfusion Medicine, Volume 36, Issue 1, Page 53-58, February 2026.Abstract Background Extracorporeal photopheresis (ECP) is a safe immunomodulatory strategy that induces cell‐type selective apoptosis through photodynamic processes. Despite decades of use, the mechanisms underlying ECP remain largely unexplored, particularly in studies examining specific immune cell subsets in ex vivo setups.

$\omega$ -cover and related spaces on the vietoris hyperspace $\mathcal F(X)$
Tạp chí Khoa học và Công nghệRecently, Tuyen et al. [1] showed that a space has a $\sigma$-(P)-strong network consisting of cs-covers (resp., $cs^*$-covers) if and only if the hyperspace $\mathcal F(X)$ does, where is one of the following properties: point finite, point countable,

A tropical approach to rigidity: Counting realisations of frameworks
Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.Abstract A realisation of a graph in the plane as a bar‐joint framework is rigid if there are finitely many other realisations, up to isometries, with the same edge lengths. Each of these finitely many realisations can be seen as a solution to a system of quadratic equations prescribing the distances between pairs of points.
