This paper describes an engineering approach to avoid RF/microwave radiation in wearable EEG data transmission by using visible light communication. The system performance was tested at different illuminance levels and an algorithm for low-illuminance operation was proposed. The authors report error-free transmission…

This computational study investigates nonlinear membrane-potential dynamics in a Fitzhugh-Nagumo single-neuron model that includes an external electromagnetic radiation term. The authors report that increasing the frequency of an external transmembrane current leads to mode selection among periodic, quasi-periodic,…

This retrospective cohort study reviewed medical records from a Swedish tertiary pain centre to assess 1-month outcomes after pulsed radiofrequency for chronic non-cancer pain. Among patients receiving lumbar median branch pulsed radiofrequency, a minority had major or minor improvement, while many had no change and…

This animal and in vitro study reports a method to lyse tumor cells mechanically using targeted superparamagnetic iron oxide nanoparticles rotated by a weak alternating magnetic field. Nude mice with head and neck tumors received cetuximab-coated nanoparticles and 4 Hz field exposures for 30 minutes on alternating…

This materials study examines how a high magnetic field affects crystallization during isothermal annealing of [(FeCo)BSi]Nb4 bulk metallic glass. The authors report that the field promotes α-(Fe,Co) precipitation and suppresses boride formation, yielding a nanocomposite microstructure with α-(Fe,Co) dispersed in an…

This materials study examined how growth rate and an external magnetic field affect microstructure and properties in directionally solidified Ag-Cu eutectic alloys. The lamellar spacing followed the Jackson-Hunt model with a reported constant of 5.8 µm³/s. Increasing magnetic field tilted eutectic growth and…

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 in vitro study examined how different external magnetic field conditions affect isoniazid release from superparamagnetic iron oxide microspheres. The abstract reports that magnetic fields accelerated drug release, with faster release in acidic (pH 3) conditions and the fastest completion (2 hours) under an…

This engineering study uses a 3D electromagnetic solver to simulate in-to-out body RF path loss for a wireless capsule endoscopy link. The capsule antenna is tuned for the 402 MHz MICS band while accounting for human body properties. The authors examine how capsule misalignment, rotation, and the human body model…

This conference paper reports an engineering approach to convert wireless microwave power into near-infrared light using a miniaturized, wirelessly powered laser. The device is described as millimeter-scale and capable of being powered through >1 cm of tissue. The abstract focuses on enabling in vivo activation of…

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 randomized animal experiment exposed 32 young female rats to 1.8 mT sinusoidal alternating electromagnetic fields at 10, 25, or 40 Hz for 90 minutes per day. The 10 Hz and 40 Hz groups had higher BMD and improved femur and lumbar vertebra biomechanical properties compared with controls, and micro-CT suggested…

This single-institution cohort analysis compared radiofrequency microtenotomy with plantar fasciotomy for recalcitrant plantar fasciitis, including a group receiving both procedures. Patient-reported outcomes (SF-36, AOFAS) and satisfaction/expectations were reportedly similar across procedures at 6 months and 1…

This laboratory/analytical study examined how sample matrix affects sample sweeping in micellar electrokinetic chromatography under an inhomogeneous electric field. It reports strong focusing for hydrophobic cationic analytes when the sample matrix conductivity is much higher than the BGE, even with low surfactant…

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 mouse study examined chronic smartphone electromagnetic radiation exposure and its effects on spatial working memory and hippocampal progenitor cell proliferation. The authors report no significant differences in Y-maze spontaneous alternation or BrdU-labeled progenitor proliferation after exposure, but…

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…
