New solitary electrostatic structures for Zakharov model in subsonic limit for solar-wind

open access: yesResults in Physics, 2022
A theoretical study of Zakharov model in subsonic limit has been investigated for plasma waves solutions via many solitary and huge structures. The electrostatic field modulations, the first integral and the rational self-focusing nonlinearly methods ...

Constraining post-Newtonian parameters with gravitational waves [PDF]

open access: yesAIP Conference Proceedings, 2001
We re-express gravitational wave results in terms of post-Newtonian parameters. Using these expressions, and some simplifying assumptions, we compute that in a favorable case, i.e. a ten solar-mass black hole spiraling in to a 10^6 solar-mass black hole, LISA observations will be able to constrain at the 10% level or better a single combination of post-

Multiobjective optimisation approaches applied to a wave energy converter design

open access: yes, 2021
The purpose of this paper is to present two different optimisation approaches for a multi-objective problem applied to PeWEC (pendulum wave energy converter), which is a pitching platform converting energy from the oscillation of a pendulum contained in ...

Integration of Serum Neurofilament Light Chain and Cortical Dysfunction Improves Diagnostic Accuracy in ALS

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine whether integration of serum neurofilament light chain (NfL) and cortical dysfunction improves diagnostic accuracy in amyotrophic lateral sclerosis (ALS) when applied alongside the Gold Coast criteria (GCC). Methods In this prospective study, 148 participants with suspected ALS were recruited (101 ALS and 47 with ALS ...

Development of evanescent wave pH sensors based on coated optical fibres [PDF]

open access: yes, 1996
The development of fibre optic ammonia and pH sensors using analyte-sensitive reagents entrapped in a sol-gel-derived silica film is presented. These sensors are based on evanescent wave absorption using unclad fibres dipcoated with the chemically ...

Study of the dynamic formation of transmission gratings recorded in photopolymers and holographic polymer-dispersed liquid crystals [PDF]

open access: yes, 2004
Local and nonlocal models for the diffusion of photopolymers are applied to the dynamic formation of transmission gratings recorded in photopolymers and holographic polymer-dispersed liquid crystals (H-PDLCs). We retrieve the main parameters of H-PDLCs (

Artificial Intelligence in Systemic Sclerosis: Clinical Applications, Challenges, and Future Directions

open access: yesArthritis Care &Research, EarlyView.
Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.

Radio over fibre distribution systems for ultra-wide band and millimetre wave applications [PDF]

open access: yes, 2011
Short range wireless technology such as ultra-wideband (UWB) and 60 GHz millimetre wave (mm-wave) play a key role for wireless connectivity in indoor home, office environment or large enclosed public areas.

Adaptive Observer for Coupled Wave PDE and Infinite ODE With Sampled Data and Unknown Input: Application to Brain Hemodynamics Estimation

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
This article proposes a convergent adaptive observer for a damped wave PDE and an infinite‐dimensional ODE coupled in cascade using sampled‐in‐space ODE state measurements. The proposed observer estimates the distributed states of the PDE and ODE along with unknown PDE parameters and spatial input.
