TL;DR: In this article, an attempt is made to measure the attenuation of emitted noise at the ITF and correlate it to the distance from the source and to seismic attenuation models in soil.

TL;DR: In this article, the authors discussed the possibility to employ the Multi-gap Resistive Plate Chambers (MRPC) of the Extreme Energy Events (EEE) Project asmuon tracking detectors to monitor the long term stability of civil buildings and structures when used in conjunction with additional detectors, to reconstruct the average direction of the cosmic muon tracks passing through both devices and any small variation over long time acquisition periods.

TL;DR: In this paper, the basic principles of a superconducting coupled cavities have been discussed and the interaction of a gravitational wave with the cavity walls is studied in the proper reference frame of the detector, and the coupling between two electromagnetic normal modes induced by the wall motion is analyzed in detail.

TL;DR: In this paper, a method used to reconstruct, in the range 10 Hz-10 kHz, the gravitational wave strain time series from the detector signals is described and the standard consistency checks of the reconstruction are discussed and used to estimate the systematic uncertainties of the $h(t)$ signal as a function of frequency.

TL;DR: The Virgo DetChar group during the O3 run achieved the addition of about 80 events to the catalog of transient gravitational-wave sources maintained by LIGO, Virgo and KAGRA, with a focus on the associated tools and the main prospects for future data-taking periods with an improved detector.
