Reverberation Chambers for Over-the-Air Tests: An Overview of Two Decades of Research
IEEE Access, 2018 The reverberation chamber (RC) has traditionally been used for electromagnetic compatibility tests. About two decade ago, it found application in various over-the-air (OTA) tests of antennas and wireless devices.

Free-Space Antenna Field/Pattern Retrieval in Reverberation Environments
, 2005 Simple algorithms for retrieving free-space antenna field or directivity patterns from complex (field) or real (intensity) measurements taken in ideal reverberation environments are introduced and discussed.Comment: 6 pages, 2 figures, submitted to IEEE ...

Altered Dynamic Functional Network Connectivity in Post‐Stroke Aphasia
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Previous studies examining post‐stroke aphasia (PSA) patients via resting‐state functional magnetic resonance imaging (rs‐fMRI) have predominantly focused on static functional connectivity. In contrast, the current investigation aims to elucidate the alterations in dynamic functional network connectivity (dFNC) among PSA patients ...

Calibrating Mg ii–based Black Hole Mass Estimators with Hβ Reverberation Measurements
Astrophysical Journal, 2019 We present the new calibration of black hole mass ( ) estimators based on the Mg ii λ2798 broad emission line using the Hβ reverberation-mapped (RM) sample of 31 active galactic nuclei (AGNs) that have high-quality UV spectra.

The Diverse Neuromuscular Spectrum of VPS13A Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective VPS13A disease (chorea‐acanthocytosis) is a rare neurodegenerative disorder caused by biallelic variants in VPS13A, typically presenting with hyperkinetic movement disorders, while neuromuscular signs are often mild. The aim of the project was to investigate the frequency and severity of neuromuscular impairment in VPS13A disease ...

The Acoustics of the Double Elliptical Vault of the Royal Palace of Caserta (Italy)
Buildings, 2017 This work investigates the acoustic characteristics of the double elliptical vault, which overlooks the Grand Staircase of the Royal Palace of Caserta (Italy). The Royal Palace was built by the architect Luigi Vanvitelli in the Seventeenth Century and it

Common mathematical framework for stochastic reverberation models.
Journal of the Acoustical Society of America, 2019 In the field of room acoustics, it is well known that reverberation can be characterized statistically in a particular region of the time-frequency domain (after the transition time and above Schroeder's frequency). Since the 1950s, various formulas have

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Cognitive impairment, fatigue, and depression are common in multiple sclerosis (MS), potentially due to disruption of regional functional connectivity caused by white matter (WM) lesions. We explored whether WM lesions functionally connected to specific brain regions contribute to these MS‐related manifestations.

Study of reverberation pattern and its cancellation method in shallow water [PDF]
Theoretical and Applied Mechanics, 2007 In shallow water, the primary limitation of the performance of active sonar is the reverberation that originates from volume and boundaries scattering as well as multi-path propagation. Therefore, reverberation cancelation is an important research topic
