MicroPhaseNO: Adapting an Earthquake-Trained Phase Neural Operator for Microseismic Phase Picking
Seismic phase picking is very often used for microseismic monitoring and subsurface imaging. Traditional manual processing is not feasible for either real-time applications or large arrays. Deep learning-based pickers trained on large earthquake catalogs offer an automated alternative.

An FCM-based microseismic phase arrival picking method and application
Artificial Intelligence in GeosciencesArtificial intelligence-based methods for picking microseismic phase arrivals have been widely adopted. However, these methods are frequently challenged by complex and dynamic monitoring scenarios, where various types of environmental noise mask low ...

KVP: a multiscale kurtosis approach for seismic phase picking
Geophysical Journal InternationalSUMMARY Automatic event detection and phase picking are critical for processing the large volumes of data produced by modern seismological instrumentation. Accurate picking is especially challenging in Distributed Acoustic Sensing (DAS) recordings, where data quality can significantly vary along segments of the fibre due to localized ...

Is the world made of loops? [PDF]
, 2018 I see no good reason to prefer (any version I know of) the `holonomy interpretation' to the `potential interpretation' of the Aharonov-Bohm effect. Everyone agrees that the inverse image $[A]=[A+d\lambda]_{\lambda}=d^{-1}F$ of the electromagnetic field ...

Controlling chaos in spatially extended beam-plasma system by the continuous delayed feedback
, 2006 In present paper we discuss the control of complex spatio-temporal dynamics in a {spatially extended} non-linear system (fluid model of Pierce diode) based on the concepts of controlling chaos in the systems with few degrees of freedom.

Phase picking errors on seismograms of seismic array
Mongolian Journal of Astronomy and GeophysicsBandpass filtering between 0.3 and 7 Hz is used in the daily seismic data analysis routine at IAG. I estimated the back azimuth of selected events from the ERMAR seismic array by F-k analysis and compared it with the back azimuth from the GSE bulletin for those events.

Self-referencing a continuous-wave laser with electro-optic modulation [PDF]
, 2015 We phase-coherently measure the frequency of continuous-wave (CW) laser light by use of optical-phase modulation and f-2f nonlinear interferometry. Periodic electro-optic modulation (EOM) transforms the CW laser into a continuous train of picosecond ...
