Gravitational waveforms in scalar-tensor gravity at 2PN relative order [PDF]

open access: yes, 2016
We compute the gravitational waveform from a binary system in scalar-tensor gravity at 2PN relative order. We restrict our calculation to non-spinning binary systems on quasi-circular orbits and compute the spin-weighted spherical modes of the radiation.

Persistence–of–straining and polymer alignment in viscoelastic turbulence

open access: yesApplications in Engineering Science, 2020
Drag reduction in turbulent flows by the addition of polymers is a phenomenon that has a variety of applications in the engineering. The highly nonlinear interactions between the turbulent flow and the polymers in the polymeric solution still impose ...

Robust brain network identification from multi-subject asynchronous fMRI data

open access: yesNeuroImage, 2021
We describe a novel method for robust identification of common brain networks and their corresponding temporal dynamics across subjects from asynchronous functional MRI (fMRI) using tensor decomposition.

Polynomial-Time Tensor Decompositions with Sum-of-Squares [PDF]

open access: yesIEEE Annual Symposium on Foundations of Computer Science, 2016
We give new algorithms based on the sum-of-squares method for tensor decomposition. Our results improve the best known running times from quasi-polynomial to polynomial for several problems, including decomposing random overcomplete 3-tensors and ...

On a ordering of area tensor elements orientations in a micropolar continuum immersed in an external plane space

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2021
The paper deals with the problems of ordering the reper orientations for a micropolar continuum immersed in an external plane space. Based on the concept of an elementary tensor volume (area) \(M\)-cells, an algorithm for comparing and matching external ...

Distinguishing Random and Black Hole Microstates

open access: yesPRX Quantum, 2021
In this work, we study the distinguishability of random states drawn from the Wishart ensemble as well as black hole microstates. We compute the relative entropy and many generalizations, including the Petz Rényi relative entropy, sandwiched Rényi ...

Gravitational Waves in Scalar–Tensor–Vector Gravity Theory

open access: yesUniverse, 2021
In this paper, we study the properties of gravitational waves in the scalar–tensor–vector gravity theory. The polarizations of the gravitational waves are investigated by analyzing the relative motion of the test particles.

Error Analysis and Correction of a Downhole Rotating Magnetic Full-Tensor Gradiometer

open access: yesIEEE Access, 2020
Compared with ground magnetic measurement and aeromagnetic survey, downhole magnetic measurements can provide more abundant and accurate distribution information of ore deposits.
