A Probability Distribution for Quantum Tunneling Times

open access: yesAdvances in High Energy Physics, 2018
We propose a general expression for the probability distribution of real-valued tunneling times of a localized particle, as measured by the Salecker-Wigner-Peres quantum clock.

Probability Distribution Functions of Sunspot Magnetic Flux

open access: yesThe Astrophysical Journal, 2023
We investigated the probability distributions of sunspot area and magnetic flux by using data from the Royal Greenwich Observatory and USAF/NOAA. We constructed a sample of 2995 regions with maximum-development areas ≥500 MSH (millionths of solar ...

Receiver orientation and event back-azimuth estimation for downhole microseismic monitoring using a probabilistic method based on P-wave polarization

open access: yesFrontiers in Earth Science, 2023
Microseismic event back-azimuth is an indispensable parameter for source localization in downhole microseismic monitoring, and the accurate orientation of horizontal components of downhole seismic receivers is vital for reliably determining the event ...

Towards a taxonomy for crypto assets

open access: yesCogent Economics & Finance, 2023
We explore the taxonomy of cryptocurrencies and integrate our analysis with traditional ways of understanding financial assets. We thus classify cryptocurrencies using the time series and distributional properties of returns.
