Sequential joint inversion of gravity and magnetic data via the cross‐gradient constraint

Geophysical Prospecting, 2021
ABSTRACTDifferent geophysical methods use different model parameterizations and inversion algorithms. Thus, combining these different inversion systems and yet adding the nonlinear cross‐gradient constraint in a joint inversion framework might be a big challenge, for instance, as explained further by Moorkamp et al.

Capillary assembly of cross-gradient particle arrays using a microfluidic chip

Microelectronic Engineering, 2015
Display Omitted Cross-gradient particle arrays (CGPA) were produced by capillary assembly.Arrays have a gradual change of composition but a constant particle density.Use of microfluidic chips enabled tuning of the gradient steepness and composition in situ.

Gravity-magnetic cross-gradient joint inversion by the cyclic gradient method

Optimization Methods and Software, 2020
In this paper, we consider a joint-inversion problem using different types of geophysical data: gravity and magnetism.

Genesis of two-dimensional patterns in cross-gradient fields

Physical Review E, 2011
Tissue morphogenesis is controlled by the two-dimensional patterning of gene expression in epithelial layers, that determines cell fates. The mechanisms of pattern formation involve intracellular regulatory networks controlled by paracrine and autocrine signaling.

The cultivation of Phaeodactylum tricornutum in crossed gradients of temperature and light

Algological Studies/Archiv für Hydrobiologie, Supplement Volumes, 2003
Phaeodactylum tricornutum BOHLIN, is one of the most important species in the algal biotests. The cultivation of this species in the crossed gradients evaluated the dependence of the growth rates and morphology on particular combinations of environmental factors (temperature, light).

Improvements to elastic full waveform inversion using cross-gradient constraints

SEG Technical Program Expanded Abstracts 2016, 2016
Seismic full-waveform inversion (FWI) is potentially a powerful method for obtaining high-resolution subsurface images, but the results are often distorted by nonlinear effects and parameter trade-offs. Such distortions can be particularly severe in the case of multiparameter FWI, such as elastic FWI, in which inversion is performed simultaneously for
