Inverse of the string theory KLT kernel

open access: yesJournal of High Energy Physics, 2017
The field theory Kawai-Lewellen-Tye (KLT) kernel, which relates scattering amplitudes of gravitons and gluons, turns out to be the inverse of a matrix whose components are bi-adjoint scalar partial amplitudes.

Wavelet-Based Three-Dimensional Inversion for Geomagnetic Depth Sounding

open access: yesMagnetochemistry, 2022
The complexity of Earth’s structure poses a challenge to the multiscale detection capability of geophysics. In this paper, we present a new wavelet-based three-dimensional inversion method for geomagnetic depth sounding.

The generalized S- and σ-inverse – a comparative case study for right- and left-invertible plants [PDF]

open access: yesBulletin of the Polish Academy of Sciences: Technical Sciences, 2020
In this paper, an advanced study covering the comparison between two classes of generalized inverses is conducted. Two sets of instances, strictly derived from the recently introduced nonunique S- and σ-inverse, are analyzed, especially in terms of ...

A 2D Lithospheric Magnetic Anomaly Field over Egypt Using Gradient Data of Swarm Mission

open access: yesUniverse, 2022
The current work makes use of the geometrical configuration of the two lower-altitude Swarm satellites (Swarm A and C), moving side by side with a longitudinal distance of 1.4°, to estimate a two-dimensional (2D) model of the lithospheric magnetic ...

The Non-Unicity of the Film Thickness in the Hydrodynamic Lubrication: Novel Approach Generating Equivalent Micro-Grooves and Roughness

open access: yesInternational Journal of Applied Mechanics and Engineering, 2021
Since the 1960s, all studies have assumed that a film thickness “ h ” provides a unique pressure field “ p ” by resolving the Reynolds equation. However, it is relevant to investigate the film thickness unicity under a given hydrodynamic pressure within ...

Time-Domain Multidimensional Deconvolution: A Physically Reliable and Stable Preconditioned Implementation

open access: yesRemote Sensing, 2021
Multidimensional deconvolution constitutes an essential operation in a variety of geophysical scenarios at different scales ranging from reservoir to crustal, as it appears in applications such as surface multiple elimination, target-oriented redatuming,

Shear‐Wave Velocity Structure of Sediments on Cascadia's Continental Margin From Probabilistic Inversion of Seafloor Compliance Data

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Several seismic techniques, both passive and active, exist for estimating the shear‐wave velocity VS structure of shallow sedimentary structures. In particular, passive compliance signals recorded by broadband ocean‐bottom seismometers (OBSs) can be used

New Insights into Long-Term Aseismic Deformation and Regional Strain Rates from GNSS Data Inversion: The Case of the Pollino and Castrovillari Faults

open access: yesRemote Sensing, 2020
We present a novel inverse method for discriminating regional deformation and long-term fault creep by inversion of GNSS velocities observed at the spatial scale of intraplate faults by exploiting the different spatial signatures of these two mechanisms.

Theory completion using inverse entailment [PDF]

open access: yes, 2000
The main real-world applications of Inductive Logic Programming (ILP) to date involve the "Observation Predicate Learning" (OPL) assumption, in which both the examples and hypotheses define the same predicate.
