Jan 1, 2025
This paper is a commentary reviewing how Bradford Hill’s epidemiological criteria can be applied to multidisciplinary evidence on RF-EMF exposure and adverse health effects. It reports that systematic reviews and meta-analyses in this area often reach substantially different conclusions, and argues that key…

This engineering study addresses measurement error in magnetoelastic resonance sensors caused by Earth's magnetic field. The authors present an antisymmetric magnetic bias field approach and compare the ribbon response to external perturbation fields against a conventional design. They report a 77% reduction in the…

This engineering paper proposes a control method for a photo-electromagnetic field (EMF)-based ammonia gas sensor that uses a wireless network and adjusts illumination light intensity. It reports that measurement error is minimized over 3 800 ppm ammonia when the concentration corresponds to an optimal illumination…
