This in vitro study exposed developing pre-B lymphocytes undergoing V(D)J recombination to low-intensity RF EMFs for 48 hours across 720–1224 MHz. The authors report a frequency- and dose-dependent decrease in recombination, with stronger reductions around 950–1000 MHz at relatively low power densities. γH2AX levels…

This study evaluated extremely low, time-varying EMF “magneto-priming” to optimize germination in foxtail millet seeds using a central composite design and response surface methodology. The authors report optimal germination at 10 Hz, 30,007 nT, and 30 minutes, with improvements in germination percentage and multiple…

This engineering paper describes a third-order continuous-time current-mode ΣΔ modulator designed for WLAN 802.11b applications. It proposes a modified current mirror integrator and a dynamic latch-based current comparator aimed at improving bandwidth, linearity, and sampling rate. The authors report >60 dB dynamic…

Jan 1, 2013
This paper presents a theoretical and experimental demonstration of a photonic RF phase shifter based on a dual-parallel Mach-Zehnder modulator using a two-drive scheme. The approach aims to mitigate residual optical carrier effects and avoid a lowest-frequency limitation from an optical filter by driving the…
