A minimal-code framework for 3D magnetotelluric inversion integrating fuzzy c-means clustering
Applied Computing and GeosciencesMagnetotelluric (MT) inversion plays a critical role in the exploration of deep mineral resources. The resistivity models produced by conventional MT inversion algorithms are smooth. Integrating fuzzy c-means (FCM) clustering into MT inversion allows for

Artificial Intelligence in GeosciencesSeismic impedance inversion is a key technique for extracting reservoir information from seismic data. Traditional model-driven inversion methods often prove inadequate when dealing with complex reservoirs, which has led to the growing adoption of data ...

Nonstationary ETAS models for nonstandard earthquakes
, 2014 The conditional intensity function of a point process is a useful tool for generating probability forecasts of earthquakes. The epidemic-type aftershock sequence (ETAS) model is defined by a conditional intensity function, and the corresponding point ...

Scene-adapted plug-and-play algorithm with convergence guarantees
, 2017 Recent frameworks, such as the so-called plug-and-play, allow us to leverage the developments in image denoising to tackle other, and more involved, problems in image processing.

, 2020 The comparison of benchmark error sets is an essential tool for the evaluation of theories in computational chemistry. The standard ranking of methods by their Mean Unsigned Error is unsatisfactory for several reasons linked to the non-normality of the ...

Possible strong symmetric hydrogen bonding in disodium trihydrogen bis(2,2'-oxydiacetate) nitrate [PDF]
, 2005 In the title compound, 2Na+·C8H11O10-·NO3-, the NaI atom is heptacoordinate with an approximately pentagonal-bipyramidal geometry. A possible strong symmetric hydrogen bond, with the H atom located at an inversion centre and an OO distance of 2.450 (2) Å,

Why do colours look the way they do? [PDF]
, 2011 A major part of the mind–body problem is to explain why a given set of physical processes should give rise to perceptual qualities of one sort rather than another.

Remote SensingGround penetrating radar (GPR) image inversion is of great significance for interpreting GPR data. In practical applications, the complexity and nonuniformity of underground structures bring noise and clutter interference, making GPR inversion problems ...

AIP AdvancesTraditional objective functions in potential field inversions commonly prioritize functionals that emphasize maximal smoothness and stability. Although this approach results in petrophysical images with smooth transitions and gradients, it often fails to
