Inferring Cenozoic Cover Thickness and Bedrock Sedimentary Material in 3D From Geophysical Data Using Machine Learning Algorithms: A Case Study in the Lockington Region, Victoria, Australia

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract This study presents a supervised machine learning approach to constructing a 3D geological model for the Lockington area in Victoria, Australia, by integrating borehole observations, geophysical surveys (magnetic, gravity, and radiometric), and elevation data.

Distance‐Dependent Stray Field Decay in Magnetically Stable Remanence Carriers: Implications for Magnetic Microscopy

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Micropaleomagnetic analysis offers a path to high‐precision reconstructions of ancient magnetic fields from terrestrial and space‐returned samples by inverting the vertical stray field of individual particles to recover their magnetic moments through the use of magnetic microscopes.

Application of Euler and Werner deconvolution techniques in delineating tin deposit in Okeso area, Southwestern, Nigeria

Proceedings of the Nigerian Society of Physical Sciences
The Okeso pegmatites field was evaluated using magnetic method within abandoned mining site close to the southeastern region of Ojoku area. The study aims to delineate, identify geological boundaries and determine depth of tin deposits in the area.

A Virtual Clinical Trial of Psychedelics to Treat Patients With Disorders of Consciousness

Advanced Science, Volume 13, Issue 11, 23 February 2026.
Disorders of consciousness after severe brain injury are marked by reduced complexity of brain activity and limited treatment options. Using personalized whole‐brain models, this study shows that simulated lysergic acid diethylamide (LSD) and psilocybin shift patient brain dynamics closer to criticality.

The application of Euler deconvolution to airborne EM datay

ASEG Extended Abstracts, 2004
Euler's equation has traditionally not been used with electromagnetic fields because of a belief that it does not apply, because EM data obey Maxwell's wave equations rather than Laplace's equation. However if two approximations are employed then this is not the case. The approximations are ; 1) the effects of displacement currents are neglected; and 2)

SketchSet: Creating Euler diagrams using Pen or Mouse [PDF]

, 2011
Euler diagrams form the basis of various visual languages but tool support for creating them is generally limited to generic diagram editing software using mouse and keyboard interaction.

Identification of magnetic structures and their tectonic implications in southwestern Cameroon using satellite aeromagnetic data

Frontiers in Earth Science
The Southwestern part of Cameroon exhibits a geologically complex framework dominated by Precambrian rocks and associated structures. Satellite aeromagnetic data were processed and interpreted using different filtering techniques, 3D Euler Deconvolution,

Derivation of New Orthonormal Basis Functions for Magnetic Detection of Submarine Telecommunications Cables

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper presents the first orthonormal basis function (OBF) framework adapted for passive magnetic detection of DC current‐carrying submarine telecommunications cables, extending Anderson's dipole‐based approach to cable‐like source configurations. Two orthonormal basis functions are derived from the Biot‐Savart law and integrated into a generalised

Deconvolution Estimation in Measurement Error Models: The R Package decon [PDF]

Data from many scientific areas often come with measurement error. Density or distribution function estimation from contaminated data and nonparametric regression with errors in variables are two important topics in measurement error models.

Introducing 3D Venn and Euler Diagrams [PDF]

, 2012
In 2D, Venn and Euler diagrams consist of labelled simple closed curves and have been widely studied. The advent of 3D display and interaction mechanisms means that extending these diagrams to 3D is now feasible.
