Remarks on Separation of Convex Sets, Fixed-Point Theorem, and Applications in Theory of Linear Operators [PDF]

open access: yes, 2007
Some properties of the linear continuous operator and separation of convex subsets are investigated in this paper and a dual space for a subspace of a reflexive Banach space with a strictly convex norm is constructed.

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.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

The Split Equality Fixed-Point Problem and Its Applications

open access: yesAxioms
It is generally known that in order to solve the split equality fixed-point problem (SEFPP), it is necessary to compute the norm of bounded and linear operators, which is a challenging task in real life.

A parallel hybrid accelerated extragradient algorithm for pseudomonotone equilibrium, fixed point, and split null point problems

open access: yesAdvances in Difference Equations, 2021
This paper provides iterative construction of a common solution associated with the classes of equilibrium problems (EP) and split convex feasibility problems.

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Critical Theory of Non-Fermi Liquid Fixed Point in Multipolar Kondo Problem

open access: yesPhysical Review X, 2020
When the ground state of a localized ion is a non-Kramers doublet, such localized ions may carry multipolar moments. For example, Pr^{3+} ions in a cubic environment would possess quadrupolar and octupolar, but no magnetic dipole, moments.

Modified Krasnoselski–Mann iterative method for hierarchical fixed point problem and split mixed equilibrium problem

open access: yesJournal of Inequalities and Applications, 2020
In this paper, we introduce a modified Krasnoselski–Mann type iterative method for capturing a common solution of a split mixed equilibrium problem and a hierarchical fixed point problem of a finite collection of k-strictly pseudocontractive nonself ...

Preliminary Measurements of the Xenon Triple Point

open access: yes, 2014
Ever since the construction and definition of the highly successful International Temperature Scale of 1990 (ITS-90), one severe deficiency of the scale has been recognized, without a reliable remedy.

Some Convergence Results for a Sequence of Gornicki Type Contractions Mappings

open access: yes, 2023
The stability of fixed points for a sequence of mappings satisfying the conditions introduced by Górnicki is studied in a metric space(X;d). In particular, these mappings are only defined on a subsetXnof themetric spaceX.
