Multifrequency Identification and Exploitation in Lamb Wave Inspection [PDF]

open access: yesIEEE Access, 2019
Lamb wave inspection provides a promising method to assess the structural health status. However, Lamb wave modes exhibit different characteristics which vary with frequency significantly. The best excitation frequency usually cannot be determined in specific applications. This work proposes a multifrequency exploitation and identification method. Lamb

Study of Lamb Waves for Non-Destructive Testing Behind Screens [PDF]

open access: yes, 2018
The inspection and control of sodium-cooled fast reactors (SFR) is a major issue for the nuclear industry. Ultrasonic solutions are under study because of the opacity of liquid sodium.

Consumer diversity drives stronger predation in tropical marine communities

open access: yesEcography, EarlyView.
Biotic interactions are predicted to be stronger in the tropics compared to higher latitudes, contributing to observed patterns of global biodiversity. While increased consumer diversity and more complex food webs are expected in tropical communities, the trophic dynamics underlying strong regional effects of predation are not well understood.

Do Big Data Applications and Financial Innovation Lead to Enhanced Banking Performance? Evidence From the United Kingdom

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT Big data and financial innovations are vital to enhancing the performance of banking institutions. However, limited evidence exists on the effects of big data applications and financial innovation on bank performance. This study addresses this gap by constructing a theoretical framework linking big data applications and financial innovations ...

Scanning laser techniques for characterisation of different surface breaking defect geometries [PDF]

open access: yes, 2012
Measurements using a laser scanning system consisting of a pulsed Nd:YAG laser to generate surface ultrasonic waves and an interferometer to detect the surface displacement, are presented for different samples and defect geometries.

Brexit and Its Impact on EU Financial Markets

open access: yesInternational Journal of Finance &Economics, EarlyView.
ABSTRACT We investigate the impact of Brexit on volatility spillovers across the EU countries. We introduce a Brexit intensity measure that assigns an intensity score reflective of the financial markets' reaction to the events that occurred as Brexit negotiations began to unfold.

Resonant States Reveal Strong Light–Matter Coupling in Nanophotonic Cavities

open access: yesLaser &Photonics Reviews, EarlyView.
Photonic resonant states reveal characteristics of coupled light–matter systems that would otherwise be hidden by damping. Their trajectories (when tuning the optical resonance) undergo a qualitative change at the onset of strong coupling: They start swapping positions.

Controlling Collective Quasiparticle Dynamics Beyond Decoherence in Topological Interfaces

open access: yesLaser &Photonics Reviews, EarlyView.
Gold nanoparticles placed above a deformed honeycomb plasmonic crystal couple to a chiral topological interface mode. The pseudospin‐split bands ψ+/ ψ− encode spin‐momentum locking, so emitters radiate directionally along the domain wall and share a common phase.
