Selection principles and covering properties in bitopological spaces

open access: yesApplied General Topology, 2020
Our main focus in this paper is to introduce and study various selection principles in bitopological spaces. In particular, Menger type, and Hurewicz type covering properties like: Almost p-Menger, star p-Menger, strongly star p-Menger, weakly p-Hurewicz,

Star-Hurewicz and related properties

open access: yesApplied General Topology, 2004
We continue the investigation of star selection principles first considered. We are concentrated onto star versions of the Hurewicz covering property and star selection principles related to the classes of open covers which have been recently introduced.

A Coarse Geometric Approach to Graph Layout Problems

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT We define a range of new coarse geometric invariants based on various graph–theoretic measures of complexity for finite graphs, including treewidth, pathwidth, cutwidth and bandwidth. We prove that, for bounded degree graphs, these invariants can be used to define functions which satisfy a strong monotonicity property, namely, they are ...

Some remarks on Pixley-Roy hyperspaces

open access: yesTạp chí Khoa học Đại học Huế: Khoa học Tự nhiên
In this paper, we study cellular-compact, cellular-Lindel\"of, strongly star-Hurewicz, strongly star-Rothberger, strongly star-Menger spaces on hyperspaces with the Pixley-Roy topology.

The Binding of Pentadiyl‐α,ω‐Bis(Dimethyldodecylammonium), a Cationic Gemini 12‐5‐12 Surfactant to Conjugated Carboxylates as Organic Counterions

open access: yesJournal of Surfactants and Detergents, EarlyView.
ABSTRACT The critical micelle concentration (CMC) values of the cationic gemini surfactant pentadiyl‐α,ω‐bis(dimethyldodecylammonium) bromide depend on the hydrophobicity of added conjugated organic carboxylate anions. Nine conjugated counterions, present as sodium salts of organic acids, were studied to expand the correlation to the counterion ...

Aberrant alternative splicing of purinergic receptor P2RX4 prevents sensitivity towards combinatorial treatment in colorectal and pancreatic cancer

open access: yesThe Journal of Pathology, EarlyView.
Abstract Recently, we suggested the combination of chemotherapy and P2RX4 inhibition as a promising novel therapeutic approach for P2RX4‐expressing epithelial tumors to prevent paracrine resistance. Here, we aimed to assess whether determining P2RX4 expression status in colorectal and pancreatic cancer patients would allow stratification of potentially

Refining the treatment of immune checkpoint inhibitor–associated myocarditis: Challenges, innovations and rechallenge considerations

open access: yesBritish Journal of Pharmacology, EarlyView.
Immune checkpoint inhibitor (ICI)‐associated myocarditis has emerged as a severe and clinically complex immune‐related toxicity that poses significant challenges for therapeutic decision‐making in routine cardio‐oncological care. High‐dose corticosteroids remain the first‐line therapy, yet their timing, dosage and tapering require careful clinical ...

Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

open access: yesIbis, Volume 168, Issue 3, Page 972-984, July 2026.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

CMR‐derived left ventricular pressure‐volume loops enhance individualized assessment of disease severity and prognosis in pulmonary arterial hypertension in adults

open access: yesPhysiological Reports, Volume 14, Issue 11, June 2026.
Abstract In pulmonary arterial hypertension (PAH), increased pulmonary vascular resistance (PVR) causes right ventricular pressure overload and left ventricular (LV) underfilling. We investigated LV mechanics and their prognostic value in PAH using cardiovascular magnetic resonance (CMR)‐derived LV pressure‐volume (PV) loops.

Comparing Two Novel LiDAR‐Based Indices for Quantifying Forest Structural Complexity

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
This study compares two LiDAR‐derived forest structural complexity indices: the fractal‐based box dimension (Db$$ {D}_b $$) and the entropy‐based canopy entropy (CE$$ CE $$). Analysis of 170 plots revealed a strong linear correlation (r = 0.823) between Db$$ {D}_b $$ and CE$$ CE $$, but computation was much slower.
