Free‐Breathing 3D Whole Heart and Aorta Cine MRI Without Contrast Agent—Comparison to Clinical Standard

Journal of Magnetic Resonance Imaging, Volume 64, Issue 2, Page 524-535, August 2026.
ABSTRACT Background The demand for cardiac MRI is increasing with the growing burden of cardiovascular disease. However, conventional protocols require sequential acquisitions for multi‐breath‐hold 2D cine and 3D MR angiography (MRA), which is time‐consuming.

The impact of tropical forests on local climate: Comparing recent research with conservation practitioner information priorities

People and Nature, Volume 8, Issue 8, Page 2828-2846, August 2026.
Abstract The local‐scale climate impacts of tropical forests (LCIF), such as reducing temperatures and increasing rainfall, are directly relevant to climate change adaptation and mitigation. Strengthening understanding of these local climate benefits can encourage actions to conserve natural forests, with positive implications for climate resilience ...

A mechanical mode-stirred reverberation chamber inspired by chaotic cavities

, 2015
A multivariate approach to the calculation of field-field correlation matrices is used to estimate the number of uncorrelated positions in a mode-stirred reverberation chamber (RC) inspired by chaotic cavities.

Studying the pulse regime in a reverberation chamber with a model based on image theory [PDF]

, 2010
6 pages - WOSInternational audienceIn this article, we propose a time-domain model of a reverberation chamber (RC). This very straightforward model based upon image theory (IT) allows to simulate the behavior of a reverberation chamber in the pulse ...

Informal Firms' Adoption and Use of Mobile Money Under Uncertain Times: Evidence From Burkina Faso

Review of Development Economics, Volume 30, Issue 3, Page 1533-1564, August 2026.
ABSTRACT This paper investigates how uncertainty affects mobile money adoption and use by informal businesses. Despite the prevalence of the informal sector in developing countries and the recognized potential of mobile money for financial inclusion, empirical research on its adoption and usage among unregistered businesses is limited.

Radiated Immunity Tests: Reverberation Chamber vs. Anechoic Chamber Results

, 2005
The paper concerns the comparison between reverberation chamber measurements (RC) and anechoic chamber (AC) measurements: in particular, the case of an immunity test is considered. A two-wire transmission line is adopted as a device under test (DUT), and

Apical hypercontractility mitigates impaired diastolic filling and lower intraventricular haemodynamic forces in human bed rest

Experimental Physiology, Volume 111, Issue 8, Page 3570-3587, 1 August 2026.
Abstract Prolonged physical inactivity alters the cardiovascular system, including the heart. Long‐term bed rest is known to decrease left ventricular volume and cause diastolic dysfunction; however, the interplay between these changes and their effect on cardiac contractility have been understudied.

A study of uncertainty models in a reverberation chamber at NIST [PDF]

, 2012
The reverberation chamber has become a good alternative for over-the-air (OTA) testing of small antennas. Here the uncertainty of total radiated power measurements is evaluated for a reverberation chamber at National Institute of Standards and Technology

A dual deformable reverberation chamber [PDF]

, 2009
There is disclosed an arrangement for measuring the effectiveness of a shielding material against electromagnetic fields. The arrangement comprises a first and a second reverberation chamber sharing a common wall.
