Adding Prior Information in FWI through Relative Entropy
Entropy, 2021 Full waveform inversion is an advantageous technique for obtaining high-resolution subsurface information. In the petroleum industry, mainly in reservoir characterisation, it is common to use information from wells as previous information to decrease the

Descriptive Epidemiology and Prognosis of Pediatric Acute Leukemia in the Afro-Descendant Population of the French West Indies and French Guiana. [PDF]
Cancer MedABSTRACT Introduction The epidemiology of acute leukemia (AL) in children in Afro‐descendant (AD) populations is poorly described, and survival is often considered worse in these populations. The aim of this study is to describe the epidemiology and prognosis of childhood AL in the AD population of the French West Indies/French Guiana (FWI/FG ...

Future Projections of Burned Area in Europe Highlight the Importance of Human Action. [PDF]
Glob Chang BiolOur simulations with two fire models and the LPJmL Dynamic Global Vegetation Model show that both biophysical and socio‐economic drivers shape future wildfire activity in Europe. Fire weather and fire management capacity dominate broad trends, while changes in land use, vegetation and population density shape regional patterns. Improved fire management

Accelerated Full Waveform Inversion by Deep Compressed Learning [PDF]
SensorsWe propose and test a method to reduce the dimensionality of Full Waveform Inversion (FWI) inputs as a computational cost mitigation approach. Given modern seismic acquisition systems, the data (as an input for FWI) required for an industrial-strength ...

Journal of Geophysical Research: Machine Learning and ComputationFull waveform inversion (FWI) reconstructs subsurface models by minimizing the mismatch between observed and simulated seismic data. However, the strong nonlinearity of the inversion problem makes gradient‐based optimization highly sensitive to ...

Atypical parkinsonian syndromes in French Guiana: Similarities and differences with Caribbean variants [PDF]
Journal of Parkinson’s DiseaseBackground Atypical parkinsonian syndromes are highly prevalent in the French West Indies (FWI), making up 70% of degenerative parkinsonisms and including “Caribbean Atypical Parkinsonism”. Environmental neurotoxins from Annonaceae plants are implicated.

Progressive plug and play full waveform inversion with multitask learning [PDF]
Scientific ReportsThe quality of low-frequency data and the initial model are crucial for robust seismic full waveform inversion (FWI). Some existing deep learning works only address one to improve the inversion accuracy.
