Fixed Point Sets of Digital Curves and Digital Surfaces

open access: yesMathematics, 2020
Given a digital image (or digital object) (X,k), we address some unsolved problems related to the study of fixed point sets of k-continuous self-maps of (X,k) from the viewpoints of digital curve and digital surface theory.

In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

INTERKONEKSITAS DALAM AJARAN SOSIAL TASAWUF SUNNI DAN FALSAFI

open access: yesKomunika, 2017
The existence of Sunni and philosophical mysticism in the study of Sufism has its own epistemology. Discussing the polemic between Sunni and philosophical Sufism is risky because instead of the differences between them, there is prevalent interrelation ...

„Jest ja, ale mnie nie ma” – granica poetyckiego szaleństwa Rafała Wojaczka

open access: yesPrzestrzenie Teorii, 2011
In this article the author made an attempt at demarcating the limits of the poetic language of Rafał Wojaczek, the crossing of which – as the author of this study thinks – opens before the poet a possibility of achieving the perfectness of the subject of

«Perfect» lions, «perfect» leaders

open access: yesJournal des africanistes, 1983
Abstract In studying lion symbolism among the Tabwa (southeastern Zaïre), the author demonstrates the fact that, although this symbolism may have been diffused in Africa from Europe in the Paleolithic age (suggestion of Frobenius), metaphors or other items of culture are adopted only if they allow people to understand and explain some aspects of their ...

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

open access: yesAdvanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Stationary consistent equilibrium coalition structures constitute the recursive core [PDF]

open access: yes
We study coalitional games where the proceeds from cooperation depend on the entire coalition structure. The coalition structure core (Kóczy, GEB, 2007) is a generalisation of the coalition structure core for such games.

Exploring Dipolar Dynamics and Ionic Transport in Metal‐Organic Frameworks: Experimental and Theoretical Insights

open access: yesAdvanced Functional Materials, EarlyView.
In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

Understanding and Optimizing Li Substitution in P2‐Type Sodium Layered Oxides for Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous
