This paper describes a system intended to encourage daily walking exercise in people with COPD. During home exercise, the platform sends SMS messages to the patient's mobile phone indicating the target exercise intensity (linked to music tempo). The abstract does not report any findings about health outcomes or…

This paper describes an aerodynamically assisted bio-jetting technique that processes living cells/organisms using differential pressure rather than an electric field. The authors report an operational window for stable jetting and near-monodispersed cell-bearing droplets. Cell viability after jetting was evaluated…

This exposure assessment measured peak magnetic fields during magnetic particle inspection, a nondestructive testing method that uses electromagnetism. Ninety-five peak measurements taken while inspecting 8 turbine engine shafts ranged from

This study reports on symptomatology and risk perception among 45 people living near power-lines in the Benevento area. Although measured electric and magnetic fields were described as being within the normal range, participants reported symptoms mainly in subjective and behavioural domains. The authors argue that…

This narrative review summarizes recent advances (as of Spring 2007) in Internet- and cell phone-based HIV prevention and intervention research. The authors report that few evaluation studies had been published in the prior year, though many programs were funded and under development. Available results are described…

This animal study evaluated two multiprobe radiofrequency ablation device approaches in pigs, including an impedance-based algorithm and clustered/combination probes with and without a switcher controller. The Pringle maneuver was associated with larger ablation volumes and shorter ablation times in one experiment,…

This retrospective case series reviewed four resections of symptomatic giant cavernous hepatic hemangiomas using an RF-powered multiarray (Habib sealer) for hepatic parenchymal transection. No blood transfusions were required and no major biliary or vascular injuries were observed at 1-year follow-up; one…

This study measured satellite structures of second- and third-harmonic spectra reflected from solid targets during femtosecond laser–plasma interactions using an optical multi-channel spectrometer. Red-shifted satellite structures of 2ω0 and 3ω0 were observed, and at ~10^18 W/cm^2 the inferred spontaneous magnetic…

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 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 dose accumulated…

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 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 using magnets and/or…
