Rapid parameter estimation for merging massive black hole binaries using continuous normalizing flows

Machine Learning: Science and Technology
Detecting the coalescences of massive black hole binaries (MBHBs) is one of the primary targets for space-based gravitational wave observatories such as laser interferometer space antenna, Taiji, and Tianqin. The fast and accurate parameter estimation of

Torsion Pendulum Apparatus for Ground Testing of Space Inertial Sensor

Sensors
The precise movement of the test mass along a geodesic is crucial for gravitational wave detection in space. To maintain this motion, the core payload-inertial sensor incorporates multiple functional units designed to mitigate various sources of stray ...

Cylindrical gravitational waves

Classical and Quantum Gravity, 1989
It is shown how the general cylindrical wave solution of Einstein's equations can be obtained from a matrix-valued generating function by adapting \textit{R. S. Ward}'s splitting construction [Gen. Relativ. Gravitation 15, 105-109 (1983; Zbl 0504.53022)].

Theoretical Model of Distributed Parameters for Eccentric Coaxial Line and Its Application in Oil Wells

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Aiming at the current demand for using wellbore coaxial lines with tubing and casing in oil wells, implementing microwave chemical‐assisted crude oil upgrading underground, and promoting “carbon‐zero” mining projects in oil field development, we carried out theoretical analysis, simulations, and applied research on the distributed parameters ...

Analysis of the effect of coupling coefficients on the slope of PDH-locked frequency discriminator

AIP Advances
The effects of the coupling coefficients on the reflected field and the error signal under various misalignments and near-axis conditions are analyzed, and some basic features of the error signal are investigated.

Electrically Induced Liquid Metal Resonance Phenomena

Advanced Physics Research, EarlyView.
This study systematically reveals electrically induced resonance phenomena in liquid metal droplets under square wave AC signal excitation through diverse voltage modulation. Volume‐dependent vibrational responses deviate from classical theoretical predictions, while geometric constraints achieve selective resonance modal control and collective ...

The spread of non‐native species

Biological Reviews, EarlyView.
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.
