This paper describes a modified approach for assessing occupational EMF exposure during work on radio and television towers and masts, where exposure can be high and tasks/routes are not fixed. The method calculates maximum admissible dwell time at different mast levels while incorporating the EMF…

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…

This randomized animal study tested whether pulsed electromagnetic field (PEMF)-induced vibration affects orthodontic tooth movement produced by magnetic and/or mechanical forces. Forty-four Wistar rats were exposed to PEMF-induced vibration or normal atmosphere while tooth movement was induced…

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,…

This engineering study describes development of a patch antenna array coil (PAAC) intended to address short RF wavelength challenges in ultra-high-field (≥7T) MRI. A prototype PAAC for 7T proton imaging was used to image a monkey brain. The authors report that the imaging demonstrated the coil's…

This paper studies chaotic mixing driven by breakup and reformation of a magnetic particle chain under a rotating magnetic field using direct numerical simulation. The authors report that chain motion and the degree of chaos depend strongly on the Mason number, and that a limited Mason number…

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…

This Physical Review Letters paper reports a method to reverse electric polarization in multiferroic TbMnO3 using a rotating magnetic-field direction, without applying an electric field or heat. The authors state that the direction of magnetic-field-induced polarization along the a axis is…

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…

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…

This paper reports that the electronic gap in bilayer graphene can be controlled externally via a gate bias (electric field effect). Using magnetotransport (Shubnikov-de Haas) data and a tight-binding model, the authors extract the gap as a function of electronic density. They report tuning the…

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.…

This paper outlines the development and evaluation of a wireless PDA-based clinical e-portfolio intended to support reflective clinical learning. The tool synchronized wirelessly via cellular signal or Wi-Fi to a web-based portfolio. An evaluation with nurse practitioner and medical students…

This in vitro study examined whether astrocyte alignment induced by an applied electric field influences neurite outgrowth. Astrocytes were pre-aligned using a physiological-strength electric field (500 mV mm(-1)), and dorsal root ganglia cells were then seeded onto them. Neurite outgrowth at 24…
