This engineering study describes an experimental setup using a small electret condenser microphone connected to a notebook/PC to detect extremely low frequency signals. Using a small air cell made from a drilled DVD plate with a speaker and microphone on opposite sides, the microphone captured…

This university-based pilot study evaluated whether two-way SMS text messaging could be used to collect situational assessment data during simulated public health critical events. Among 63 enrolled students, 76.7% of prompted SMS surveys were completed, and most responses were returned quickly.…

This animal study evaluated whether magnetic field exposure affects breast tumor growth and viability in mice injected with breast cancer cells. Tumor growth was monitored in real time using luciferase labeling and an in vivo imaging system. The authors report that 360 minutes of daily magnetic…

This clinical study evaluated micro-plasma radio frequency treatment for facial acne scars in 24 patients. Patients received 3–5 treatments and were assessed using photographs before and 2 months after treatment. The authors report an overall improvement rate of 83.33% and conclude the technique…

This article reports an engineering implementation of a wireless sensor network-based remote water-level monitoring system. The system includes field sensors, a base station, a data center, and a web publishing module, and is described as providing real-time monitoring and anti-jamming capability.…

This in vitro study exposed newborn rat calvarial osteoblasts to 50 Hz sinusoidal electromagnetic fields at 1.8 mT for different daily exposure times (0.5–3.0 h). The authors report inhibited osteoblast proliferation at longer exposure times, alongside increased differentiation markers (ALP…

This paper reports a MAXWELL 3D simulation study of electric field distribution in a tissue/tumor model relevant to electrical-pulse-mediated drug delivery. The authors report lower electric field strength in tumor tissue compared with normal cells. They interpret this as potentially increasing…

This paper reports the development of a 15-channel transmit-receive RF coil for 7 T human brain MRI, using a hybrid decoupling approach to support element placement along three axes. The design is presented as enabling B1+ shimming and parallel imaging acceleration in three dimensions, with…

This paper describes a new magnetization transfer 31P MRS approach (MT-ISIS) for measuring the creatine kinase forward reaction rate in the human brain using a volume 31P/1H RF coil on a clinical 3-T MRI system. The method aims to reduce acquisition time (30 min), avoid scalp muscle contamination,…

This experimental and modeling study examined pulsed electric field (PEF) permeabilization in several fruit and vegetable tissues at 293 K using 1000 μs pulses and field strengths of 400 and 1000 V·cm(-1). While electroporation theory predicts greater damage in tissues with larger cells, the…

The paper evaluates how pulsed electric field (PEF) processing affects milk volatile compounds compared with HTST pasteurization (75 °C, 15 s). GC-MS detected 37 volatiles and reported some compositional differences between PEF and pasteurized milk, including increased aldehydes and lower methyl…

This engineering-focused mouse fMRI study evaluated a 400-MHz cryogenic RF probe (CryoProbe) versus a conventional room-temperature surface coil during electrical forepaw stimulation. The CryoProbe increased image SNR and temporal SNR and reduced temporal noise compared with the room-temperature…

This engineering study describes modifying MRI RF transmit coil electric-field distributions to create electric field-free zones without substantially changing transmit sensitivity. Phantom experiments are reported to show reduced implant heating when a zero electric-field plane is aligned with…

This study investigated how exposure to a static magnetic field affects electricity production in Shewanella-inoculated microbial fuel cells across different reactor configurations. A 100 mT field was reported to increase maximum voltage and the effect was described as immediate and reversible,…

This in vitro study examined whether extremely low-frequency magnetic fields affect chondrogenic differentiation of human mesenchymal stem cells in pellet culture. Cells exposed for 3 weeks to a homogeneous sinusoidal 5 mT magnetic field showed increased collagen type II expression (significant at…
