On Classes of Hyperfunctions of Rank 2 Generated by Maximal Multiclones

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2017
The research of multifunctions is a one of the directions in discrete function’s investigations. Multifunction is a discrete function from a finite set A to all subsets of A. The set of hyperfunctions is a subset of set of multifunctions.

A new type of generalized closed set via ?-open set in a fuzzy bitopological space [PDF]

open access: yes, 2019
This paper aims to present the notion of (i, j)*-fuzzy γ-open set in a fuzzy bitopological space as a parallel form of (i, j)-fuzzy γ-open set due to Tripathy and Debnath (2013) [17] and show that both of them are independent concepts. Then we extend our

Classification of Multioperations of Rank 2 by E-precomplete Sets

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2020
In this paper multioperations defined on a two-element set and their closure operator based on composition operator and the equality predicate branching operator is considered. The composition operator is based on union of sets.

Some Results of Feebly Open and Feebly Closed Mappings

open access: yesمجلة بغداد للعلوم, 2009
The main purpose of this paper is to study feebly open and feebly closed mappings and we proved several results about that by using some concepts of topological feebly open and feebly closed sets , semi open (- closed ) set , gs-(sg-) closed set and ...

Extremal Union-Closed Set Families [PDF]

open access: yes, 2019
A family of finite sets is called union-closed if it contains the union of any two sets in it. The Union-Closed Sets Conjecture of Frankl from 1979 states that each union-closed family contains an element that belongs to at least half of the members of ...

Experience With Performing Rheocarna Therapy via the Single‐Needle Method for Treatment of Chronic Limb‐Threatening Ischemia

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction This study investigated the safety and efficacy of single‐needle Rheocarna therapy for chronic limb‐threatening ischemia (CLTI) with wounds. Methods Six patients with CLTI involving ulcers unresponsive to revascularization underwent single‐needle Rheocarna treatment.

Closed loop identification based on quantization [PDF]

open access: yes, 2002
This paper proposes a new closed-loop identification scheme for a single-input-single-output control loop. It is based upon a quantizer inserted into the feedback path. The quantizer can be used to generate an equivalent persistently exciting signal with

OnNeutrosophic Crisp g#x Closed Set Operators [PDF]

open access: yesNeutrosophic Sets and Systems
The concept of g#α closed set in general topological spaces was first introduced by Muthukumaraswamy K et. al.,. Recently, kokilavani V, Tharani K et. al., introduced neutrosophic crisp g#α closed set in neutrosophic crisp topological space. Now, in this

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Topological set theories and hyperuniverses [PDF]

open access: yes, 2012
We give a new set theoretic system of axioms motivated by a topological intuition: The set of subsets of any set is a topology on that set. On the one hand, this system is a common weakening of Zermelo-Fraenkel set theory ZF, the positive set theory GPK ...
