Investigation of Slow-Moving Artificial Slope Failure with Multi-Temporal InSAR by Combining Persistent and Distributed Scatterers: A Case Study in Northern Taiwan

open access: yesRemote Sensing, 2020
In Taiwan, landslides pose serious threats to local residents and infrastructures each year due to high mountain relief and distinct seasonal precipitation distribution.

Optimal Quantum Phase Estimation [PDF]

open access: yesPhysical Review Letters, 2009
By using a systematic optimization approach we determine quantum states of light with definite photon number leading to the best possible precision in optical two mode interferometry. Our treatment takes into account the experimentally relevant situation of photon losses.

Machine Learning for Quantum Metrology

open access: yesProceedings, 2019
Phase estimation represents a significant example to test the application of quantum theory for enhanced measurements of unknown physical parameters. Several recipes have been developed, allowing to define strategies to reach the ultimate bounds in the ...

Multitaper estimates of phase-amplitude coupling [PDF]

open access: yesJournal of Neural Engineering, 2021
Abstract Phase-amplitude coupling (PAC) is the association of the amplitude of a high-frequency oscillation with the phase of a low-frequency oscillation. In neuroscience, this relationship provides a mechanism by which neural activity might be coordinated between distant regions.

Phase Estimation of Single Tones Next to Modulated Signals in the Medium Frequency R-Mode System

open access: yesIEEE Access, 2022
Position, navigation, and timing information are critical to today’s infrastructures; as a result, the possibility of estimating ranges is being explored in more and more radio systems. One way to achieve this is to extend the modulation with time-

Efficient Bayesian Phase Estimation [PDF]

open access: yesPhysical Review Letters, 2016
We provide a new efficient adaptive algorithm for performing phase estimation that does not require that the user infer the bits of the eigenphase in reverse order; rather it directly infers the phase and estimates the uncertainty in the phase directly from experimental data.

A new estimator for phase statistics

open access: yesJournal of Cosmology and Astroparticle Physics, 2022
Abstract We introduce a novel statistic to probe the statistics of phases of Fourier modes in two-dimensions (2D) for weak lensing convergence field κ. This statistic contains completely independent information compared to that contained in observed power spectrum.

Directional Statistics and Filtering Using libDirectional

open access: yesJournal of Statistical Software, 2019
In this paper, we present libDirectional, a MATLAB library for directional statistics and directional estimation. It supports a variety of commonly used distributions on the unit circle, such as the von Mises, wrapped normal, and wrapped Cauchy ...
