Some star and strongly star selection principles

Topology and its Applications, 2017
Star selection principles first introduced and studied by Kocinac et al. in [10] and [2] are investigated. In particular we consider the relationship between the star-Menger, strongly star-Menger as well as the relationship between star covering ...

On Strongly Star g-Compactness of Topological Spaces

Tatra Mountains Mathematical Publications, 2023
In this paper, we introduce strongly star g-compactness as a topological covering property and compare its structure to other topological properties that have analogous structures. The characteristics of a strongly star g-compact subset and strongly star

Combinatorial aspects of selective star covering properties in Ψ-spaces [PDF]

, 2014
Which Isbell–Mrowka spaces (Ψ-spaces) satisfy the star version of Menger's and Hurewicz's covering properties? Following Bonanzinga and Matveev, this question is considered here from a combinatorial point of view.

The t/k-diagnosability and strong Menger connectivity on star graphs with conditional faults

Theoretical Computer Science, 2019
The t / k -diagnosis, a famous diagnosis strategy, is proposed by Somani and Peleg. In this strategy, all the faulty vertices, no more than t, can be isolated into a faulty set, which may contain no more than k fault-free vertices. Somani and Peleg ( [16]

Characterizations of weakly star-type Rothberger and Menger properties in hyperspaces

Filomat, 2023
In this paper, we introduce the selection principles wSS* 1(??(?),C?(?)), wSS* fin(??(?),C?(?)), wS* 1(??(?),C?(?)) and wS* fin(??(?),C?(?)) to characterize the properties of weakly strong-star Rothberger (Menger) and weakly star-Rothberger (Menger ...

Endoscopically assessed mucus parameters in equine asthma: Relationship to clinical history and cytological findings data

Equine Veterinary Journal, EarlyView.
Abstract Background Mucus parameters are hallmark diagnostic features of equine asthma (EA). Objectives To investigate the relationship between mucus quantity score and mucus viscosity score with signalment, history, clinical findings and cytological parameters. Study Design Retrospective cross‐sectional study.

How much sampling is enough? Four decades of understorey bird mist‐netting across Amazonia define the minimum effort to uncover species assemblage structure

Ibis, EarlyView.
Mist‐net sampling comprises a key methodological component of assemblage‐wide avifaunal studies, particularly in the understorey of closed‐canopy tropical forests. To investigate mist‐net bird captures and species assemblage structure, we compiled data from 312 sites across the Pan‐Amazon.

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

Ibis, EarlyView.
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 ...

Pollution Permits and Financing Costs

Journal of Money, Credit and Banking, EarlyView.
Abstract Effective environmental policy should consider how the financiers of polluting firms behave. We study phase III of the EU Emission Trading System. Loan spreads for cap‐and‐trade participants are a function of compliance costs, permit market features, and firms’ strategic actions.

Digitalisation of International Trade in Intellectual Properties: An Approach Based on the Utility Theory of Technology Value

The World Economy, EarlyView.
ABSTRACT In the era of globalisation and digital transformation, international trade has expanded beyond traditional goods and services to include the exchange of intellectual properties (IPs), particularly technology. As intangible assets become key drivers of global economic growth, accurately valuing them remains a complex challenge due to their ...
