A very general covering property
, 2011 v.2 largely expanded and improved; v.3: just pointed out that the definitions of Menger and Rothberger are nonstandard in the published journal ...

On the minimal cover property in
Topology and its Applications, 2014 Abstract We investigate in ZF set theory, i.e. Zermelo–Fraenkel set theory minus the Axiom of Choice AC , the set-theoretic strength of the following statements MCC : Every topological space with the minimal cover property is compact and, MCP : For every infinite set X, the Tychonoff product 2 X , where 2 = { 0

FEBS Open Bio, EarlyView.Bioscience students were asked for their opinions on the value and teaching of skills. 204 responded that teamwork, time management and study skills are necessary to reach University, that scientific writing, research, laboratory and presentation skills are taught effectively during their studies, while other skills are gained inherently through study ...

Numerical properties of Chern classes of certain covering manifolds
, 1999 In this paper, we study numerical properties of Chern classes of certain covering manifolds. One of the main results is the following: Let ψ : X → Pn be a finite covering of the n-dimensional complex projective space branched along a hypersurface with ...

Applications of δ-Open Sets via Separation Axioms, Covering Properties, and Rough Set Models
Journal of MathematicsIn this article, we make use of δ-open sets to establish some topological concepts related to separation axioms and covering properties and to propose novel topological rough set models.

A family of covering properties [PDF]
Mathematical Research Letters, 2008 In the first part of this paper I present the main results of my Ph.D. thesis: several proofs of the singular cardinal hypothesis $\SCH$ are presented assuming either a strongly compact cardinal or the proper forcing axiom $\PFA$. To this aim I introduce a family of covering properties which imply both $\SCH$ and the failure of various forms of square.

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs
FEBS Open Bio, EarlyView.Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for

This paper covers the theory of the uncovered set used in the literatures on tournaments and spatial voting. I discern three main extant definitions, and I introduce two new concepts that bound exist- ing sets from above and below: the deep uncovered set

EFFICIENT STORAGE AND COMPRESSION OF COVERING ARRAYS USING ADVANCED ENCODING TECHNIQUES
Journal of Engineering Science (Chişinău)This paper introduced a novel storage format for covering arrays, designed to optimize file size through efficient compression techniques. The proposed format employed Asymmetric Numeral System (ANS) encoding for array data, as well as Run ...

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA
FEBS Open Bio, EarlyView.PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.
