Photoinactivation and Photoablation of Porphyromonas gingivalis

open access: yesPathogens, 2023
Several types of phototherapy target human pathogens and Porphyromonas gingivitis (Pg) in particular. The various approaches can be organized into five different treatment modes sorted by different power densities, interaction times, effective ...

Tatouage audio par EMD [PDF]

open access: yes, 2013
In this paper a new adaptive audio watermarking algorithm based on Empirical Mode Decomposition (EMD) is introduced. The audio signal is divided into frames and each one is decomposed adaptively, by EMD, into intrinsic oscillatory components called ...

Mode I and Mode II Crack Tip Asymptotic Fields with Strain Gradient Effects

open access: yes, 2001
The strain gradient effect becomes significant when the size of fracture process zone around a crack tip is comparable to the intrinsic material length l, typically of the order of microns.

Numerical study of delamination process of the CFRP composite

open access: yesFracture and Structural Integrity
A quasi-static approach for an interface damage model, incorporating Rayleigh damping for viscoelastic carbon fiber reinforced polymer composites, is introduced. The interface traction-relative displacement behavior is modeled using a thin adhesive layer,

The Antifungal Action Mode of N-Phenacyldibromobenzimidazoles

open access: yesMolecules, 2021
Our study aimed to characterise the action mode of N-phenacyldibromobenzimidazoles against C. albicans and C. neoformans. Firstly, we selected the non-cytotoxic most active benzimidazoles based on the structure–activity relationships showing that the ...

Toward the end-to-end optimization of the SWGO array layout

open access: yesNuclear Physics B
In this document we consider the problem of finding the optimal layout for the array of water Cherenkov detectors proposed by the SWGO collaboration to study very-high-energy gamma rays in the southern hemisphere.

Mode I Fracture Toughness of Tangential Moso Bamboo

open access: yesBioResources, 2014
This paper discusses moso bamboo (Phyllostachys pubescens) with initial crack formation by a three-point bending (SENB) method. The corrected indentation load-displacement curve (ISO 13586-2000) and the crack opening displacement in determining the crack
