Entropy generation and current density of tangent hyperbolic Cu-C2H6O2 and ZrO2-Cu/C2H6O2 hybridized electromagnetic nanofluid: A thermal power application

open access: yesSouth African Journal of Chemical Engineering, 2023
Maintaining a continuous thermal convective power supply is very essential in many industries and thermal systems, this is because it helps in improving the efficiency of engineering machines and engines.

Multi-Attribute Decision Making Based on Attribute Importance Degree and Case-Based Reasoning

open access: yesCybernetics and Information Technologies, 2013
To tackle a multi-attribute decision making problem, rough set and casebased reasoning are often combined. However, the reduction in a rough set is always complex.

Characterizations of the dilation of frame generator dual pairs for group

open access: yesJournal of Inequalities and Applications, 2019
In this paper, we are interested in the dilation problem on frame generator dual pairs for a unitary representation in Hilbert spaces. We show the existence of a Riesz generator dilation dual pair of a frame generator dual pair in Hilbert spaces. Then we

The Three Terms Task - an open benchmark to compare human and artificial semantic representations

open access: yesScientific Data, 2023
Word processing entails retrieval of a unitary yet multidimensional semantic representation (e.g., a lemon’s colour, flavour, possible use) and has been investigated in both cognitive neuroscience and artificial intelligence.

Eliminating the wave-function singularity for ultracold atoms by a similarity transformation

open access: yesPhysical Review Research, 2020
A hyperbolic singularity in the wave function of s-wave interacting atoms is the root problem for any accurate numerical simulation. Here, we apply the transcorrelated method, whereby the wave-function singularity is explicitly described by a two-body ...

Large‐Diameter DNA‐Scaffolded Nanopores Enabled by Loosely Packed Peptides for Single‐Molecule Sensing

open access: yesAngewandte Chemie, EarlyView.
A nanopore composed of transmembrane peptides and a DNA scaffold that assists peptide assembly was constructed. By employing peptides containing the unnatural amino acid 2‐aminoisobutyric acid (Aib), which promotes loose packing between helices, a large‐diameter nanopore was achieved.

Exploring the Structure of Spatial Representations.

open access: yesPLoS ONE, 2016
It has been suggested that the map-like representations that support human spatial memory are fragmented into sub-maps with local reference frames, rather than being unitary and global. However, the principles underlying the structure of these 'cognitive

Similarity vs unitary similarity and perturbation analysis of sign characteristics: Complex and real indefinite inner products

open access: yes, 2006
For selfadjoint and unitary matrices with respect to indefinite inner products on finite dimensional complex or real vector spaces, the unitary similarity relation is studied in contrast to the similarity relation.

Scientific Representations as Limiting Cases [PDF]

open access: yes, 2011
In this essay, I shall show that the so-called inferential (Suárez 2003 and 2004) and interpretational (Contessa 2007) accounts of scientific representation are respectively unsatisfactory and too weak to account for scientific representation (pars ...
