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 the importance of including both sexes in animal studies – insights from home‐cage monitoring

Biological Reviews, EarlyView.
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.

Kannan-type cyclic contraction results in $2$-Menger space [PDF]

Mathematica Bohemica, 2016
In this paper we establish Kannan-type cyclic contraction results in probabilistic 2-metric spaces. We use two different types of $t$-norm in our theorems. In our first theorem we use a Hadzic-type $t$-norm.

Fixed points of set-valued mappings in Menger probabilistic metric spaces endowed with an amorphous binary relation

Applied General Topology, 2023
In this paper, we prove the existence of fixed point results for set-valued mappings in Menger probabilistic metric spaces equipped with an amorphous binary relation and a Hadžić -type t-norm.

A Coarse Geometric Approach to Graph Layout Problems

Journal 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 Observations on the Mildly Menger Property and Topological Games [PDF]

, 2022
In this paper, we defined two new games-the mildly Menger game and the compact-clopen game. In a zero-dimensional space, the Menger game is equivalent to the mildly Menger game and the compact-open game is equivalent to the compact-clopen game.

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

Journal 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 ...

TITIK-ANTARA DI DALAM RUANG METRIK DAN RUANG INTERVAL METRIK

Barekeng, 2007
A point p in metric space ()dX, is called a between-point of if Xba∈,()()(bpdpadbad,,,+= ). This concept was formulated by Menger in 1928. If all the between-points of a and b is collected in a set, then a and b are that set automaticlly. In the metric

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

The 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

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 ...
