A Review on Acoustic Emission Testing for Structural Health Monitoring of Polymer-Based Composites

open access: yesSensors, 2023
Acoustic emission (AE) has received increased interest as a structural health monitoring (SHM) technique for various materials, including laminated polymer composites.

Embedded vortices [PDF]

open access: yesPhysical Review D, 1998
We present a discussion of embedded vortices in general Yang-Mills theories. The origin of a family structure of solutions is shown to be group theoretic in nature and a procedure for its determination is developed. Vortex stability can be quantified into three types: Abelian topological stability, non-Abelian topological stability, and dynamical ...

Spoken and Sign Language Emergence: A Comparison

open access: yesLanguages, 2022
A comparison of emerging signed languages and creole languages provides evidence that, when language is emerging, it prioritizes marking the novelty of information; is readily recursive; favors the manner of action (aspect) over the time of action (tense)

La focalisation des conditionnelles

open access: yesDiscours, 2014
The aim of this article is to identify the different syntactic modes existing in French to focus if-clauses in constructions such as {if-P, Q}, and {Q if-P}.

p -embeddings

open access: yesTopology and its Applications, 2013
In 2013, the authors introduced the notion of \(p\)-extension of rings [Contemporary Mathematics 609, 19--32 (2014; Zbl 1302.13012)]. An extension of rings \(R \hookrightarrow S\) is a \(p\)-extension if for each \(s\in S\) there is an \(r\in R\) such that \(sS = rS\).

LncRNA-Disease Associations Prediction Based on Neural Network-Based Matrix Factorization

open access: yesIEEE Access, 2023
Numerous experiments have demonstrated that long non-coding RNA (lncRNA) play an important role in various systems of the human body. LncRNA deletions or mutations can cause human disease. The prediction of lncRNA-disease associations is conducive to the

Mean-field embedding of the dual fermion approach for correlated electron systems [PDF]

open access: yes, 2013
To reduce the rapidly growing computational cost of the dual fermion lattice calculation with increasing system size, we introduce two embedding schemes. One is the real fermion embedding, and the other is the dual fermion embedding.

Density matrix embedding: A strong-coupling quantum embedding theory [PDF]

open access: yes, 2012
We extend our density matrix embedding theory (DMET) [Phys. Rev. Lett. 109 186404 (2012)] from lattice models to the full chemical Hamiltonian. DMET allows the many-body embedding of arbitrary fragments of a quantum system, even when such fragments are ...

Terminal embeddings

open access: yesTheoretical Computer Science, 2017
In this paper we study {\em terminal embeddings}, in which one is given a finite metric $(X,d_X)$ (or a graph $G=(V,E)$) and a subset $K \subseteq X$ of its points are designated as {\em terminals}. The objective is to embed the metric into a normed space, while approximately preserving all distances among pairs that contain a terminal.

A Comparative Study of Sample Preparation for Staining and Immunodetection of Plant Cell Walls by Light Microscopy

open access: yesFrontiers in Plant Science, 2017
Staining and immunodetection by light microscopy are methods widely used to investigate plant cell walls. The two techniques have been crucial to study the cell wall architecture in planta, its deconstruction by chemicals or cell wall-degrading enzymes ...
