This pilot randomized study evaluated systemic extremely low-frequency magnetic field (ELF-MF) therapy versus sham in 37 women with fibromyalgia using a crossover sequence. The abstract reports significant short-term reductions in pain and improvements in fibromyalgia-related symptom and function questionnaires…

This engineering paper reports a prototype wearable patient-monitoring device that transmits vital-sign measurements via Bluetooth LE during MRI. Across 7 MRI acquisitions (25 minutes total), the authors report no Bluetooth packet loss, increased PPG noise during MRI, and no effect on temperature/humidity readings.…

This computational study used finite element modeling to estimate the electric field distribution in the brain during tDCS for two electrode montages targeting the left DLPFC. It systematically varied isotropic tissue conductivity profiles to assess sensitivity of predicted E-field magnitude and components in the…

This conference paper describes the design and simulation of coil geometries intended to produce a highly uniform magnetic field for scleral search coil eye-movement recordings without restricting head motion. The authors built a large (2.2 m per side) coil frame and compared measured magnetic flux density to…

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 exposure assessment study measured personal and bedroom extremely low-frequency magnetic field (ELF-MF) exposures in 172 children (5–13 years) in Switzerland and Italy. Geometric mean exposures were low on average (0.04 μT personal; 0.05 μT bedroom), but were higher among children living within 100 m of a…

This engineering study evaluates how anatomical/geometric differences affect MRI RF safety metrics. Simulations and a bovine-phantom experiment found that similar transmit B-field patterns can coincide with notably different peak SAR and temperature rise. The authors highlight challenges in using…

This engineering paper presents an experimentally validated wearable personal exposimeter system for RF-EMF exposure monitoring, motivated by increasing wireless applications. It uses a distributed measurement approach and integrates inertial sensors to capture activity and posture during measurements. The system is…

This animal organ-preservation study compared 12-hour porcine heart preservation at -3°C using a device generating a variable magnetic field versus conventional 4°C preservation. The subzero variable-magnetic-field condition showed higher myocardial ATP, lower lactate, and less mitochondrial ultrastructural damage…

This Data in Brief article provides additional experimental data supporting a related study on mitigating ageing effects (Staebler-Wronski effect) in hydrogenated amorphous silicon solar cells. The associated method involves applying reverse bias stress and evaluating how temperature, electric field intensity,…

This longitudinal analysis evaluated cell phone messaging (texts and calls) as a tool for community Ebola syndromic surveillance in Moyamba District, Southern Sierra Leone (Aug–Oct 2014). The authors report that the cell phone alert system captured suspect and confirmed Ebola cases and mortality alerts, with many…

This randomized controlled trial evaluated whether mobile phone SMS messages could improve healthy food choices among Iranian postmenopausal women. Over 4 months, the intervention group received 16 messages about healthy food selection. The study reports increased consumption of Vitamin A rich fruits and vegetables…

This cross-sectional survey assessed how rural-based advanced midwives in South Africa perceive and use mobile phones for education and professional activities. Among 56 respondents, most reported frequent use of mobile phone functions to support work and learning despite low self-rated technology competence and…

This engineering study addresses inter-cell interference in LTE networks as a driver of packet loss between base stations and mobile stations. It examines Soft Frequency Reuse (SFR) and implements a new hybrid frequency reuse method with greater total system bandwidth than SFR while keeping per-cell bandwidth the…

This paper describes development of a fully implantable biotelemetry system that wirelessly transmits cardiac biomechanical force data along with ECG. The system uses a microcontroller with a bidirectional RF transceiver and was tested in a porcine model. The authors report successful transmission and recording of…

This engineering/food science study measured dielectric constant (ε'), dielectric loss factor (ε″), and power penetration depth in beef and gravy preparations across 27–1,800 MHz and 20–130 °C. The dielectric properties generally decreased with increasing frequency, and penetration depth decreased with increasing…

This in vitro study examined whether electromagnetic fields (EMFs) influence chondrogenic differentiation of bovine mesenchymal stem cell pellets, with and without the inflammatory cytokine IL-1β. The authors report EMFs had limited effects on chondrogenesis in the absence of inflammation, but in the presence of…

This workplace measurement study assessed intermediate frequency (IF) and extremely low frequency (ELF) magnetic field exposure among cashiers working near electronic article surveillance (EAS) systems in Finnish stores. Typical seated exposures were reported as well below limits, but short-term exceedances of ICNIRP…

This food science study assessed how UV irradiation, pulsed electric field, hot water dip, and ethanol vapour treatments affected mung bean sprout quality and storage life at room and low temperatures. The abstract reports minimal effects on sprout growth metrics, with ethanol suppressing length/weight, hot water dip…

This engineering study assesses optimal RF frequencies for wireless communication with intraoral electronic devices using an intraoral tongue drive system as an example. It compares 27 MHz, 433.9 MHz, and 2.48 GHz based on path loss, radiation patterns, and bit error rate tests, with adaptive impedance matching…
