Exploring multivalued probabilistic ψ-contractions with orbits in b-Menger spaces
Vojnotehnički GlasnikIntroduction/purpose: The paper presents a novel approach to certain well-established fixed point theorems for multivalued probabilistic contractions in b-Menger spaces, leveraging the boundedness of the orbits.

On the importance of including both sexes in animal studies – insights from home‐cage monitoring
Biological Reviews, Volume 101, Issue 5, Page 2408-2426, October 2026.ABSTRACT A review of behavioural studies using home‐cage monitoring (HCM) systems revealed that over 61% of studies used only male subjects, with only 24% including both sexes, despite evidence of substantial behavioural differences between male and female animals. This bias could influence the outcomes of biomedical research.

A Coarse Geometric Approach to Graph Layout Problems
Journal of Graph Theory, Volume 113, Issue 2, Page 169-194, October 2026.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 ...

Common fixed point theorems in Menger spaces
International Journal of Mathematics and Mathematical Sciences, 2006 We proved two common fixed point theorems for four self-mappings and two set-valued mappings with φ-contractive condition in a Menger space.

Synthese Unkonventioneller α‐Polyhalogenierter Amine Durch Hydroaminoalkylierung
Angewandte Chemie, Volume 138, Issue 38, 14 September 2026.Es wird ein redox‐neutrales Verfahren beschrieben, bei dem Alkene und Alkine unter Verwendung stabiler Hemiaminal‐Reagenzien in α‐Polyhalogenmethylamine umgewandelt werden. Dieser Ansatz ermöglicht den Zugang zu α‐CF3‐, α‐CF2H‐, α‐CF2Cl‐, und α‐CFClH‐Aminen und besticht durch ein breites Substratspektrum, eine hohe Toleranz gegenüber funktionellen ...

Carl Menger: «Principios de Economía Política» [PDF]
La objetivación del valor de los bienes, que es por su propia naturaleza totalmente subjetivo, crea mucha confusión. Respecto del valor de un diamante, es indiferente que haya sido descubierto por puro azar o que se hayan empleado mil días de duros ...

Angewandte Chemie, Volume 138, Issue 38, 14 September 2026.Eine nicht‐kanonische C16‐Sesquiterpensynthase aus Morganella morganii produziert das ungewöhnliche Grundgerüst Descartan. Ihr Cyclisierungsmechanismus wurde mittels Isotopenmarkierungsexperimenten und DFT‐Berechnungen aufgeklärt. Gezielte Mutagenese veränderte die Enzymfunktion und führte zu alternativen Produkten, darunter Voltairen, dessen ...

On semi-Menger and nearly Menger spaces
In continuation of the study of semi-Menger and nearly Menger properties in a topological space, we discuss some characterizations of semi-Menger and nearly Menger spaces, and derive the relation of these spaces to other well-known spaces.

Angewandte Chemie, Volume 138, Issue 38, 14 September 2026.Nach einer weitverbreiteten Annahme erfährt der Cobalt‐basierte Fischer‐Tropsch‐Katalysator eine anfängliche Aufrauung, die zu einer Aktivitätssteigerung führt und vom hohen chemischen Potential des Kohlenstoffs getrieben wird. In der vorliegenden Operando‐STM‐ und DFT‐Untersuchung simulieren wir solche Bedingungen.
