This experimental physics study examines how a static electric field affects the optical nonlinearity of methyl-red doped nematic liquid crystals. The authors report that low voltages below the Fredericks transition threshold can change the optical nonlinearity by orders of magnitude. They state that the data fit a…

This in vitro study tested whether a weak electric field reconstructed from duodenal spiking potentials during an MMC cycle affects bacterial adhesion to Caco-2 intestinal epithelial cells. The MMC-related electric field increased adhesion of Lactobacillus and Lactococcus strains, while two pathogenic strains…

This engineering study updates a prior (2005) survey on electromagnetic interference (EMI) affecting infusion pumps and extends testing to DECT phones and WiFi terminals. It reports a reduced failure rate for GSM phone exposure compared with 2005 (58% to 30%). The authors report that WiFi and DECT did not pose a real…

This engineering conference paper describes a single access point method for localizing a subject using RF signals from wearable wireless sensors. The approach combines RSSI and LQI measurements from one basestation and applies filtering. The abstract reports that accuracy can approach that of multi-basestation…

This engineering study reports using radio-frequency (RF)-based dielectric heating to assist NaOH pretreatment of switchgrass to improve enzymatic digestibility. Under the stated conditions, RF-assisted pretreatment produced higher xylose and glucose yields than conventional heating and maintained higher yields at…

This paper describes an exposure and microscopy system designed to continuously observe living cells during exposure to modulated RF-EMF similar to mobile phone signals. Using protocols where the same cells serve as controls before and after exposure, the system was validated with endocytosis measurements. Under 900…

This study reports measurements in 25 dental patients treated with the Viofor JPS system using extremely low frequency magnetic fields. Following a series of treatments, oral cavity electropotentials decreased and saliva pH increased. Copper levels in non-stimulated saliva decreased, while other measured elements…

This in vitro study measured biophoton/chemiluminescence emission from MDCK cells after inducing reactive oxygen species with hydrogen peroxide. The authors report that photon emission increased with hydrogen peroxide dose and that photomultiplier tube measurements agreed with fluorescence microscopy observations.…

This laboratory study examined whether a weak alternating magnetic field tuned to the cyclotron frequency of Ca2+ and K+ ions influences fusion of tobacco and soya protoplasts. The abstract reports a 2–3× increase in protoplast fusion frequency under exposure. It also reports involvement of calcium ions in induction…

This engineering study examines multi-wall carbon nanotubes suspended in water exposed to AC electric fields generated by 3D electrodes. It reports field-induced polarization leading to nanotube alignment and long-range, electrically conducting assemblies spanning the electrode gap, with assembly length controlled by…

This paper models extravascular MRI signal decay (R2/R2*) as a function of blood oxygenation, vessel geometry, and magnetic field strength up to 9.4 T using Monte Carlo diffusion simulations. It reports different vessel-size dependencies for Hahn-spin-echo versus gradient-recalled-echo relaxation across field…

This laboratory study tested microwave radiation (10 and 60 mW/cm2 for 5, 30, or 60 minutes) on fungal and actinomycetal spores grown on agar and on common building materials under wet and dry humidity conditions. Reported effects on spore viability depended on strain, growth conditions, humidity, power density, and…

This paper reports analytical theory on how a small solenoidal magnetic field affects an ion-beam pulse propagating through background plasma. The authors predict enhanced self-electric and self-magnetic fields under a resonance-like condition (omegace ≈ omegape beta_b) attributed to a dynamo effect. The combined…

This physics study reports ultranarrow optical absorption and two-phonon excitation spectroscopy of Cu2O paraexcitons in a high magnetic field at 1.2 K. A magnetic field enabled observation of an otherwise forbidden paraexciton absorption line and allowed measurement of field-dependent oscillator strength and energy…

This Physical Review Letters study investigates phase competition between spin- and orbital-ordered states in a DyVO3 single crystal. The abstract reports reentrant temperature-driven transitions in spin ordering and orbital ordering. It also reports that an applied magnetic field can switch between orbital-ordered…

This theoretical paper investigates Beresinskii-Kosterlitz-Thouless vortex physics in two-dimensional superconductors under an external magnetic field using a sine-Gordon field-theory approach. The authors state that the model yields a straightforward definition of field-induced magnetization. They also report that…
