Photoemission Evidence for a Remnant Fermi Surface and d-Wave-Like Dispersion in Insulating Ca2CuO2Cl2

open access: yes, 1999
An angle resolved photoemission study on Ca2CuO2Cl2, a parent compound of high Tc superconductors is reported. Analysis of the electron occupation probability, n(k) from the spectra shows a steep drop in spectral intensity across a contour that is close ...

Multi-sensor fire detection by fusing visual and non-visual flame features [PDF]

open access: yes, 2010
This paper proposes a feature-based multi-sensor fire detector operating on ordinary video and long wave infrared (LWIR) thermal images. The detector automatically extracts hot objects from the thermal images by dynamic background subtraction and ...

Heat wave Intensity Duration Frequency Curve: A Multivariate Approach for Hazard and Attribution Analysis

open access: yesScientific Reports, 2019
Atmospheric warming is projected to intensify heat wave events, as quantified by multiple descriptors, including intensity, duration, and frequency. While most studies investigate one feature at a time, heat wave characteristics are often interdependent ...

1.2 ASSESSMENT OF DIASTOLIC FUNCTION IN PAEDIATRIC PATIENTS BY MEANS OF WAVE INTENSITY ANALYSIS DERIVED FROM CARDIOVASCULAR MAGNETIC RESONANCE IMAGING

open access: yesArtery Research, 2013
Evaluating diastolic function in children remains a topic of clinical discussion and a gold standard measurement technique is still lacking. Wave intensity analysis can provide insight into ventricular filling mechanisms and ventriculo-vascular coupling,

Percutaneous Coronary Intervention Enhances Accelerative Wave Intensity in Coronary Arteries.

open access: yesPLoS ONE, 2015
BackgroundThe systolic forward travelling compression wave (sFCW) and diastolic backward travelling decompression waves (dBEW) predominantly accelerate coronary blood flow.

Quantification and prediction of extreme events in a one-dimensional nonlinear dispersive wave model

open access: yes, 2014
The aim of this work is the quantification and prediction of rare events characterized by extreme intensity in nonlinear waves with broad spectra. We consider a one-dimensional non- linear model with deep-water waves dispersion relation, the Majda ...

A Systematic Review of Wave Speed and Wave Intensity Measures in the Human Carotid Arteries

open access: yesArtery Research
Wave intensity and wave speed are measures used to assess the dynamic properties of the arteries and travelling waves within the circulation. Wave intensity and wave speed measured in the carotid artery have the potential to provide hemodynamic and ...

Resonant elastic soft x-ray scattering in oxygen-ordered YBa_2Cu_3O_{6+delta}

open access: yes, 2011
Static charge-density wave (CDW) and spin-density wave (SDW) order has been convincingly observed in La-based cuprates for some time. However, more recently it has been suggested by quantum oscillation, transport and thermodynamic measurements that ...

P1.4 HEMODYNAMICS OF PULMONARY HYPERTENSION: APPLICATION OF THE RESERVOIR-WAVE APPROACH

open access: yesArtery Research, 2015
Using the reservoir-wave approach, previously we characterized pulmonary vasculature mechanics with multiple interventions in a canine model. In the present study, we measured high-fidelity pulmonary arterial (PA) pressure, Doppler flow velocity, and ...
