Quasi fuzzy delta compact spaces and a few related properties [PDF]

arXiv, 2023
In this paper, we introduce the concept of various types fuzzy delta $(\delta)$ compactness such as Quasi fuzzy delta compact, Quasi fuzzy countably delta compact, Weakly fuzzy delta compact, $a$-delta compact, Strong fuzzy delta compact, Ultra fuzzy delta compact and Fuzzy delta compact and characterize these types of fuzzy delta compactness using the

Mapping Hsp104 interactions using cross‐linking mass spectrometry

FEBS Open Bio, EarlyView.
This study examines how cross‐linking mass spectrometry can be utilized to analyze ATP‐induced conformational changes in Hsp104 and its interactions with substrates. We developed an analytical pipeline to distinguish between intra‐ and inter‐subunit contacts within the hexameric homo‐oligomer and discovered contacts between Hsp104 and a selected ...

Polynomial Compactness in Banach Spaces [PDF]

Rocky Mountain Journal of Mathematics, 1998
We investigate infinite dimensional Banach spaces equipped with the initial topology with respect to the continuous polynomials. We show nonlinear properties for this topology in both the real and the complex case. A new property for Banach spaces, polynomial Dunford-Pettis property, is introduced.

Effects of cardiac motion on dose distribution during stereotactic arrhythmia radioablation treatment: A simulation and phantom study

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Cardiac motion may degrade dose distribution during stereotactic arrhythmia radioablation using the CyberKnife system, a robotic radiosurgery system. This study evaluated the dose distribution changes using a self‐made cardiac dynamic platform that mimics cardiac motion. Methods The cardiac dynamic platform was operated with amplitudes

On Fuzzy Feebly Compact Space

Wasit Journal for Pure Sciences
The object of this work to introduce a new form of fuzzy compact space in  a fuzzy topological space, named by fuzzy feebly compact space. It is stronger than a fuzzy compact space.

Compact-bounded topological groups [PDF]

arXiv, 2022
We will study two subclasses of the class of feebly compact spaces in the class of (para)topological groups, the compact-bounded and weakly compact-bounded spaces, both introduced by J. Angoa, Y. F. Ortiz-Castillo and A. Tamariz-Mascar\'ua in [4]. Also, we will study the $r$-weakly compact-bounded subsets of a topological space $X$.

On mappings of compact spaces into Cartesian spaces

Topology and its Applications, 2000
AbstractEilenberg proved that if a compact space X admits a zero-dimensional map f:X→Y, where Y is m-dimensional, then there exists a map h:X→Im+1 such that f×h:X→Y×Im+1 is an embedding. In this paper we prove generalizations of this result for σ-compact subsets of arbitrary spaces.

Some remarks on bv(s)-metric spaces and fixed point results with an application

Nonlinear Analysis, 2020
We compare the newly defined bv(s)-metric spaces with several other abstract spaces like metric spaces, b-metric spaces and show that some well-known results, which hold in the latter class of spaces, may not hold in bv(s)-metric spaces.

Compactness and collective compactness in spaces of compact operators

Journal of Mathematical Analysis and Applications, 1981
AbstractThis is a study of compactness in (a) spaces Kb(X, Y) of compact linear operators, (b) injective tensor products X \̃boϵ Y, and (c) spaces Lc(X, Y) of continuous linear operators, and its various relationships with equicontinuity and collective compactness.

Products of straight spaces with compact spaces

Applied General Topology, 2007
[EN] A metric space X is called straight if any continuous real-valued function which is uniformly continuous on each set of a finite cover of X by closed sets, is itself uniformly continuous. Let C be the convergent sequence {1/n : n ϵ N} with its limit 0 in the real line with the usual metric. In this paper, we show that for a straight space X, X × C
