This exposure assessment study analyzed smartphone-logged 4G LTE RSSI and GPS data from adults in France to identify determinants of downlink signal strength. RSSI varied with geospatial factors (distance to antennas, antenna density, urbanicity) and time of day, and was also influenced by technical smartphone…

This paper presents a machine-learning method to estimate ground-level electromagnetic radiation (electric field strength) in the near field of 5G base stations, using multiple technical and environmental input parameters. The authors report experimental performance with a mean absolute percentage error of about…

This exposure assessment measured RF-EMF levels in 21 state hospitals in Samsun Province, Turkey using short-term, long-term, and band-selective approaches across 100 kHz–3 GHz (total) and 27 MHz–3 GHz (band-selective). The study reports that the ICTA 3 V/m limit was exceeded in at least some hospital measurements,…

This study used real-time measurements on a university campus to examine how the number of users relates to RF electric field strength from cellular systems and a Wi-Fi access point. The authors report empirical models that estimate E from user counts, with stated accuracies of 86% for cellular-related measurements…

This engineering/food-processing study evaluates pulsed electric field (PEF) treatment of fresh Artrhospira platensis biomass to enhance aqueous extraction of C-phycocyanin. Extraction depended on electric field strength, treatment time, and application temperature, with higher temperatures reducing the required…

This laboratory study examined how UV-C radiation, an electromagnetic field, microwave radiation, and ultrasound affected polyphenolic compounds in chokeberry. Using UPLC-PDA-MS/MS, the authors report that UV-C, microwaves, and ultrasound generally increased several polyphenolic groups, while the electromagnetic…

This engineering conference paper describes a method for controlling the locomotion of swallowable wireless capsule endoscopy devices using a dynamic magnetic field generated by external coils. A permanent magnet embedded in the capsule is manipulated by adjusting external field strengths to maintain equilibrium for…

This study evaluated gamma radiation and static magnetic field treatments on soybean seeds stored for six months and then subjected to accelerated ageing. The authors report that certain gamma doses (3–5 kGy) and magnetic field strengths (100–200 mT) helped maintain seed protein/oil characteristics and antioxidant…

This engineering/physical chemistry study quantified interfacial electric fields in dye-sensitized solar cells using a newly described electroabsorption signature. Reported field strengths depended on the electrolyte cation (higher for divalent cations) and were linked to TiO2(e−) + I3− charge recombination kinetics…

This occupational exposure assessment monitored surgeons during 11 surgeries using monopolar electro surgery units and measured electric and magnetic field strengths during cutting and coagulating modes. Electric fields near the cable at 10 cm were reported in the hundreds of V/m, while magnetic fields were

This paper proposes a reversible approach to tune Mie scattering resonances in random media using external low induction magnetic fields. The experimental demonstration uses ultrasound in emulsions of fluorinated ferrofluid droplets dispersed in a Bingham fluid. Magnetic-field-induced droplet deformation is reported…

This paper presents a theoretical model of a single ferromagnetic particle with finite coupling between its magnetic moment and particle body in a rotating magnetic field. It describes synchronous and asynchronous motion regimes, including planar motion at low frequencies and a precession regime at high frequencies,…

This in vitro experimental study examined how an AC electric field influences actin filament (F-actin) movement on a myosin-coated substrate. The authors report that the field induces electro-orientation torque that aligns movement perpendicular toward electrode edges, with alignment increasing with field strength.…

This engineering study investigated factors affecting electro-dewatering of activated sludge under a horizontal applied electric field. It reports optimal performance without altering sludge pH or conductivity and finds that CPAM conditioning improves and accelerates dewatering. The authors provide operating…

This paper presents a theoretical description of nonequilibrium dynamics in a three-dimensional Fermi-Hubbard model driven by an external electric field. The authors report direction-dependent damping of Bloch oscillations and the emergence of a long-lived transient prethermalized state over a broad range of field…
