This animal study exposed rats of different early-life ages to 950 MHz UHF electromagnetic radiation for 30 minutes per day (SAR 1.0–1.3 W/kg) across gestation and/or early postnatal periods. The authors report no evidence of oxidative stress by TBARS or protein carbonyls, but report changes in fatty acid…

This engineering/physical chemistry study develops an analytical model and uses computer simulations to describe the electric field in oxide films during thermal metal oxidation. It reports that the electrostatic potential drop across the bulk oxide is often limited to about kBT/e, suggesting most of a larger overall…

This laboratory study investigates various ionic liquids using an electrophoresis of a charged droplet method in a dielectric liquid under an applied electric field. While charged droplets typically bounce between electrodes, the authors report that some ionic liquids exhibit a retreating behavior. They interpret…

This animal study compared rat liver and blood serum enzyme activities after a total two-hour exposure to low-intensity 900 MHz electromagnetic fields delivered as either a single or fractional schedule. The authors report that creatine kinase (liver and serum) and serum alkaline phosphatase were the most sensitive…

The paper reviews and analyzes mechanisms for resonance action of extremely weak alternating magnetic fields (40 nT) combined with weak static fields (40 μT), tuned to cyclotron frequencies. It references prior reports of narrow resonant peaks in electrical conductivity of aqueous solutions and biomedical effects in…

This study reports implementation of a passive RFID system to passively track patient flow in a radiation therapy clinic using readers/antennae in linac vault areas. Across 4302 treatment fractions from 144 patients, the system achieved about 70% read reliability and enabled comparison of median in-vault treatment…

This cross-sectional survey study (LEXNET project) examined how subjective exposure knowledge relates to risk perception (RP) for different RF EMF sources. Respondents were more concerned about base stations than other sources. Regression results suggested that most exposure-characteristic features (except distance)…

This cross-sectional survey sampled general practitioners in Germany to assess EMF knowledge and its relationship to concern about EMF health risks. Four latent knowledge groups were identified, with 43.1% giving mainly correct answers and 14.0% answering mostly "don't know". Concern was not related to knowledge…

This laboratory study examined pulsed magnetic field (PMF) pretreatment of soybean seeds (1500 nT) at 0.1–100 Hz for 5 hours/day over 20 days. The abstract reports increased germination rates for all PMF treatments, with 10 and 100 Hz showing the strongest responses, and improvements in several seedling growth and…

This engineering study investigates resonance behavior in diabolo metal bar optical antennas using FDTD numerical simulations and a dipole oscillator model. It reports that narrowing the antenna waist increases optical absorption and near-field enhancement at resonance and produces a red-shift in resonant…

This laboratory study examined Rayleigh-Bénard convection in liquid gallium under varying strengths of a uniform imposed horizontal magnetic field. Using ultrasonic velocity profiling and temperature monitoring, the authors mapped a regime diagram across Ra and Q and identified five flow regimes. The results describe…

This study measured atmospheric VOCs at the Gongga Mountain base station using weekly samples collected in 2007 and analyzed by preconcentration plus GC-MS. It reports mean concentrations of TVOCs and NMHCs, describes VOC composition, and uses PCA-based receptor modeling to attribute sources. The authors report…

This engineering study describes a handheld microfluidic preconcentrator that uses dielectrophoresis generated by circular microelectrodes with a stepping electric field. Numerical simulations were used to illustrate the electric-field concept. In experiments, HeLa cells were reportedly preconcentrated within 160…

This engineering paper describes low-power wireless sensor nodes and a cluster-based dynamic-tree hierarchical WSN architecture for monitoring historical buildings and wooden artifacts for early pest detection. The authors report simulation and demonstration results indicating improved scalability and reliability…

This article reports an engineering implementation of a wireless sensor network-based remote water-level monitoring system. The system includes field sensors, a base station, a data center, and a web publishing module, and is described as providing real-time monitoring and anti-jamming capability. The authors state…

This modeling study applies uniform electric fields parallel and normal to 180° ferroelectric domain walls in PbTiO3 and computes equilibrium structures using anharmonic lattice statics. The authors report that electric fields can substantially increase domain wall thickness and identify a critical field Ec above…

This condensed-matter physics study examined how high magnetic fields and pressure affect magnetization, transport, and thermodynamic properties of the intermediate-valence compound YbPd. The authors report that the Yb valence state and two first-order transitions are stable up to 55 T, while increasing pressure…

This laboratory/materials study examined deformation and swelling of magnetic field sensitive polymer gels (ferrogels) in a static, uniform magnetic field. The authors report that gels with randomly distributed magnetic particles exhibited weak magnetodeformation, whereas gels with aligned particles showed no…

This laboratory study investigates how magnetic field and pressure affect valence and magnetic transitions in the compound EuPtP. High-field analysis suggests a mixed valence state at low temperature and discontinuous changes in Eu2+ fraction at two transition temperatures. Pressure increases the transition…
