In this paper we define and investigate nearly Hurewicz spaces and their star version. It is shown that a nearly Hurewicz space fits between Hurewicz and almost Hurewicz spaces.

A tropical approach to rigidity: Counting realisations of frameworks
Abstract A realisation of a graph in the plane as a bar‐joint framework is rigid if there are finitely many other realisations, up to isometries, with the same edge lengths. Each of these finitely many realisations can be seen as a solution to a system of quadratic equations prescribing the distances between pairs of points.

Some Common Fixed Point Theorems in Menger PM Spaces
Employing the common property (E.A), we prove some common fixed point theorems for weakly compatible mappings via an implicit relation in Menger PM spaces. Some results on similar lines satisfying quasicontraction condition as well as -type contraction

Menger-Hausdorff metric and common fixed point theorems in Menger probabilistic G-metric spaces [PDF]
AbstractIn this paper, we introduce the concepts of generalized probabilistically bounded set $\Omega^{*}$ Ω ∗ and Menger-Hausdorff metric $\widetilde{G}^{*}$ G

Abstract figure legend AII amacrine cells are an important class of interneuron in the vertebrate retina. In addition to traditional chemical synapses these cells communicate with other neurons and with each other via electrical synapses. (A) Electrical synapse strength between AII amacrine cells was measured using dual whole‐cell patch‐clamp ...

Fixed Points of Weakly Compatible Mappings Using Common (E.A) Like property
The aim of this paper is to prove common fixed point theorems in Menger spaces using implicit relation and common (E.A) like property. An example is derived to support our main result. We extend our result to four finite families of self mappings.

FIXED POINT THEOREM OF KANNAN-TYPE MAPPINGS IN GENERALIZED FUZZY METRIC SPACES [PDF]
Binayak et al in [1] proved a fixed point of generalized Kannan type-mappings in generalized Menger spaces. In this paper we extend gen- eralized Kannan-type mappings in generalized fuzzy metric spaces. Then we prove a fixed point theorem of this kind of

Alle Seltenerdelemente bilden bekanntlich tri‐ und auch di‐valente Verbindungen. Wenige tetra‐valente Verbindungen sind auch bekannt; kürzlich wurden die ersten Moleküle und Kristalle mit Praseodym(+5) synthetisiert. Der hier definierte atomare Ionisations‐Quotient IQ legt nahe, dass Ln(+4)‐Verbindungen mit geeigneten Liganden für fast alle 4f‐Elemente

Titania nanoplates are assembled into supraparticles (SPs) using an emulsion‐based technique. These SPs are encapsulated within a polystyrene shell, applying a surface‐initiated photocatalyzed radical polymerization procedure. By varying the duration of UV light exposure, the organic fraction of the polymer is tunable.

Some fixed point results in Menger spaces using a control function [PDF]
Here we prove a probabilistic contraction mapping principle in Menger spaces. This is in line with research in fixed point theory using control functions which was initiated by Khan et al. [Bull. Austral. Math.
