On the Menger covering property and $D$-spaces [PDF]
Proceedings of the American Mathematical Society, 2012 The main results of this note are: It is consistent that every subparacompact space $X$ of size $\omega_1$ is a $D$-space; If there exists a Michael space, then all productively Lindel\"of spaces have the Menger property, and, therefore, are $D$-spaces; and Every locally $D$-space which admits a $\sigma$-locally finite cover by Lindel\"of spaces is a ...

Abstract and Applied Analysis, 2011 We prove the generalized Hyers-Ulam-Rassias stability of a general system of Euler-Lagrange-type quadratic functional equations in non-Archimedean 2-normed spaces and Menger probabilistic non-Archimedean-normed spaces.

Some Results on Best Proximity Points of Cyclic Contractions in Probabilistic Metric Spaces
Journal of Function Spaces, 2015 This paper investigates properties of convergence of distances of p-cyclic contractions on the union of the p subsets of an abstract set X defining probabilistic metric spaces and Menger probabilistic metric spaces as well as the characterization of ...

Dibenzazepin‐verbrückte Netzwerk‐Polymer‐Phthalocyanine als abbaubare heterogene Photokatalysatoren
Angewandte Chemie, EarlyView.Photodynamische Dibenzazepin‐Brücke wurde in Zink‐ und Kobalt‐Netzwerk‐Polymer‐Phthalocyanine (NP‐Pcs) eingeführt, um abbaubare heterogene Photokatalysatoren zu erhalten. Zum ersten Mal spielt die Bestrahlung mit Licht eine Schlüsselrolle beim „Design, der Verwendung und dem Abbau” von NP‐Pcs.

Completely Baire spaces, Menger spaces, and projective sets [PDF]
Topology and its Applications, 2019 W. Hurewicz proved that analytic Menger sets of reals are $ $-compact and that co-analytic completely Baire sets of reals are completely metrizable. It is natural to try to generalize these theorems to projective sets. This has previously been accomplished by $V = L$ for projective counterexamples, and the Axiom of Projective Determinacy for positive ...

On spaces with star kernel Menger
Acta Mathematica Hungarica, 2023 Given a topological property $\mathcal{P}$, a space $X$ is called star-$\mathcal{P}$ if for any open cover $\mathcal{U}$ of the space $X$, there exists a set $Y\subseteq X$ with property $\mathcal{P}$ such that $St(Y,\mathcal{U})=X$; the set $Y$ is called a star kernel of the cover $\mathcal{U}$.

British Journal of Clinical Pharmacology, EarlyView.Aims Since their emergence on the drug market, synthetic cannabinoids (SC) are still gaining increasing importance in forensic toxicology. The representatives of the so‐called new psychoactive substances have in common that they have not undergone preclinical safety studies. Hence, knowledge on toxicokinetic (TK) data is sparse.

Some remarks on almost Menger spaces and weakly Menger spaces
Publications de l'Institut Mathematique, 2015 A space X is almost Menger (weakly Menger) if for each sequence (Un : n ? N) of open covers of X there exists a sequence (Vn : n ? N) such that for every n ? N, Vn is a finite subset of Un and ?n?N ?{V : V ? Vn} = X (respectively, ?n?N ?{V : V ? Vn} = X).

On variants of θ-Menger spaces
Filomat, 2023 In this paper we further study ?-Menger, ?-almost Menger and ?-weakly Menger properties [13] and investigate their relationships with other selective covering properties. We prove that in extremally disconnected semi-regular spaces, the properties viz.

This Woman's Work: On the Relationship Between Creative and Reproductive Cognitive Labor
Gender, Work &Organization, EarlyView.ABSTRACT Persistent gender inequality in creative industries is typically explained through exclusionary networks, precarity, and discrimination. This article shifts focus to the cognitive and temporal dynamics that may influence such inequality. Drawing on dyadic interviews with Canadian parents who work or previously worked in creative fields, it ...
