Construction of some algebras of logics by using intuitionistic fuzzy filters on hoops

AIMS Mathematics, 2021
In this paper, we define the notions of intuitionistic fuzzy filters and intuitionistic fuzzy implicative (positive implicative, fantastic) filters on hoops. Then we show that all intuitionistic fuzzy filters make a bounded distributive lattice. Also, by

Congruence relations on finitary models [PDF]

Czechoslovak Mathematical Journal, 1992
The theory of congruence lattices of universal algebras is one of the most rich and developed parts of contemporary algebra. Unfortunately, the rather special and purely internal definition of the congruence relation does not extend directly to structures other than sets with operations; in fact it even does not apply to the slightly more general ...

Colloidal Heterostructures Enable Interfacial Transport of Immiscible Molecules in Printable Organohydrogels

Advanced Materials, EarlyView.
Multiphase printable organohydrogels with tunable microstructures are developed to control molecular transport pathways for immiscible cargo. The tortuosity and domain size of the colloidal phases are tuned by adjusting temperature and shear during processing, which enables the tailoring of diffusion kinetics due to different transport pathways.

On Zero-Divisor Graphs of Z_n When n Is Square-Free

Axioms
In this article, some properties of the zero-divisor graph Γ(Zn) are investigated when n is a square-free positive integer. It is shown that the zero-divisor graph Γ(Zn) of ring Zn is a (2k−2)-partite graph when the prime decomposition of n contains k ...

Transformation of citizenship regimes in Serbia since 1990: The key elements [PDF]

Filozofija i Društvo, 2011
The discussion on citizenship in Serbia, as laid out in this paper, is a proposal to look at the citizenship regimes as reflections of (changing) trends in the ways the body of citizens and nation is being conceptualized and consequently managed ...

Macrophages Mediate Mesoscale Brain Mechanical Homeostasis

Advanced Materials, EarlyView.
We investigated the role of infiltrating immune cells in sculpting the developing brain. Using Brillouin microscopy and active microrheology, we found microglia actively maintain tissue viscoelasticity. Moreover, colony stimulating factor one receptor (CSF1R)‐driven stromal remodeling alters brain mechanics in vivo. These findings link immune activity,

Rough sets based on fuzzy ideals in distributive lattices

Open Mathematics, 2020
In this paper, we present a rough set model based on fuzzy ideals of distributive lattices. In fact, we consider a distributive lattice as a universal set and we apply the concept of a fuzzy ideal for definitions of the lower and upper approximations in ...

Congruence modules related to Eisenstein series [PDF]

Annales Scientifiques de l’École Normale Supérieure, 2003
The author studies the structure of congruence modules associated with Eisenstein series in various contexts in the \(\Lambda\)-adic theory of elliptic modular forms. Fix a prime number \(p\geq 5\) and a positive integer \(N\) prime to \(p\). For each pair of Dirichlet characters \((\Theta,\psi)\) such that the product of their conductors is either \(N\

Diameter Dependence of Light Absorption in GaAs Nanowires Evidenced by Photoluminescence Spectroscopy

Advanced Optical Materials, EarlyView.
Photoluminescence spectroscopy is introduced as a qualitative method to probe light absorption in highly phase‐pure GaAs nanowire arrays and single nanowires, for which direct absorption measurements are challenging. Using defect‐line saturation and the exciton‐to‐plasma transition as indicators for the density of photogenerated charge carriers, a ...
