BITERNARY OPPOSITION AS AN ELEMENT OF MULTIPOLAR SOCIO-CULTURAL SYSTEM DESCRIPTION LANGUAGE IN POSTSTRUCTURAL ANTHROPOLOGY

open access: yesКонцепт: философия, религия, культура, 2019
The target of research is the structuralist and poststructuralist paradigm of describing and explaining cultural constants through binary or ternary semiotic codes. The author’s hypothesis, based on anthropological theories of V. Turner and Cl.

New Results Regarding the Construction Method for D‑optimal Chemical Balance Weighing Designs

open access: yesActa Universitatis Lodziensis. Folia Oeconomica, 2020
We study an experiment in which we determine unknown measurements of p objects in n weighing operations according to the model of the chemical balance weighing design. We determine a design which is D‑optimal. For the construction of the D‑optimal design,

Crystallinity and phase separation induced morphological modulation for efficient ternary all-polymer solar cells

open access: yesAPL Energy, 2023
All-polymer solar cells (all-PSCs) have attracted enormous attention and achieved significant progress in recent years due to their long-term stability and excellent film stretchability.

A study on the number of edges of some families of graphs and generalized Mersenne numbers

open access: yesRatio Mathematica, 2022
The relationship between the Nandu sequence of the SM family of graphs and the Generalized Mersenne numbers is demonstrated in this study. Nandu sequences are related to the two families of SM sum graphs and SM Balancing graphs.

Ternary Syndrome Decoding with Large Weight [PDF]

open access: yes, 2019
The Syndrome Decoding problem is at the core of many code-based cryptosystems. In this paper, we study ternary Syndrome Decoding in large weight. This problem has been introduced in the Wave signature scheme but has never been thoroughly studied.

Porous ternary Pt-based branched nanostructures for electrocatalytic oxygen reduction

open access: yesElectrochemistry Communications, 2022
The oxygen reduction reaction (ORR) is pivotal for optimizing the energy output of fuel cells and metal-air batteries; however, their commercialization is precluded by the intolerable cost, instability, earth-scarcity of Pt that remains a prestigious ...

Balances and Abelian Complexity of a Certain Class of Infinite Ternary Words [PDF]

open access: yes, 2010
A word $u$ defined over an alphabet $\mathcal{A}$ is $c$-balanced ($c\in\mathbb{N}$) if for all pairs of factors $v$, $w$ of $u$ of the same length and for all letters $a\in\mathcal{A}$, the difference between the number of letters $a$ in $v$ and $w$ is ...

Varieties whose tolerances are homomorphic images of their congruences [PDF]

open access: yes, 2012
The homomorphic image of a congruence is always a tolerance (relation) but, within a given variety, a tolerance is not necessarily obtained this way. By a Maltsev-like condition, we characterize varieties whose tolerances are homomorphic images of their ...

Applications of Multi-Valued Quantum Algorithms [PDF]

open access: yes, 2007
This paper generalizes both the binary Deutsch-Jozsa and Grover algorithms to $n$-valued logic using the quantum Fourier transform. Our extended Deutsch-Jozsa algorithm is not only able to distinguish between constant and balanced Boolean functions in a ...

High-Performance Ternary Organic Solar Cells Enabled by Combining Fullerene and Nonfullerene Electron Acceptors

open access: yesOrganic Materials, 2019
Recently, by elaborately designing nonfullerene acceptors and selecting suitable polymer donors great progresses have been made towards binary organic solar cells (OSCs) with power conversion efficiencies (PCEs) over 15%. Ternary organic photovoltaics by
