This laboratory study examined pulsed magnetic field (PMF) pretreatment of soybean seeds (1500 nT) at 0.1–100 Hz for 5 hours/day over 20 days. The abstract reports increased germination rates for all PMF treatments, with 10 and 100 Hz showing the strongest responses, and improvements in several seedling growth and…

This engineering study reports theoretical analysis and experimental demonstration of an S-tapered optical microfiber integrated with ferrofluid for magnetic-field tunability. The transmission spectrum and dip wavelengths were found to vary with magnetic-field intensity, with a Langevin-like response and a linear…

This study models nematic liquid crystals embedded in random polymer networks, where disorder disrupts long-range order and produces a glassy state. It uses simulations and an Imry-Ma-like analytic approach to visualize domains, predict domain size, and calculate the response to an applied electric field. The authors…

This paper theoretically investigates magnetic-field-induced phenomena in bent-core nematic liquid crystals, focusing on how molecular biaxiality modifies the response. Using molecular field and Landau theory, it reproduces reported experimental trends such as an enhanced Cotton-Mouton effect and an increase in the…

This animal study tested whether pre-exposure to microwave radiation from a GSM mobile phone simulator could induce a radioadaptive response to a subsequent lethal whole-body gamma dose. In mice, pre-exposure to microwave radiation, low dose rate gamma radiation, or both was associated with significantly different…

This paper reports three cases of upper limb critical ischemia with chronic hand/finger defects treated using radiofrequency upper thoracic sympathectomy (thermolysis). The authors state that standard conservative treatments had failed and surgery was initially not indicated. They report the intervention was…

This in vitro study examines RF-induced heat production in citrate-capped gold nanoparticle suspensions while minimizing confounding Joule heating from ionic buffers. It reports size-dependent heating detectable only for ≤10 nm particles, with heating scaling with concentration and surface area and being attenuated…

This engineering study addresses measurement error in magnetoelastic resonance sensors caused by Earth's magnetic field. The authors present an antisymmetric magnetic bias field approach and compare the ribbon response to external perturbation fields against a conventional design. They report a 77% reduction in the…

This physics study analyzes circular wave packets in high Rydberg states produced by applying a pulsed electric field to extreme Stark states. It reports a position-dependent energy gradient that creates a correlation between principal quantum number and spatial coordinate, which appears insensitive to the initial…

This animal experiment assessed integral and pulsed bioelectric activity across rabbit brain regions during exposure to low-intensity magnetic and electromagnetic fields. The authors report that brain-region participation in CNS reactions varied across exposure parameters and conditions and depended strongly on…

This paper describes an engineering device for wireless microscopy using a mobile phone and a WiFi system. The system allows recording, displaying, and storing microscopic images from a remote end via wireless LAN. Conceptual demonstrations are reported for monitoring common objects and liver cancer cells, with…

This randomized, placebo-controlled, double-blind, cross-over trial evaluated a wrist-applied PEMF bracelet in 18 migraine patients and examined possible modulation of placebo effects. In the overall group, both PEMF and placebo were associated with similar reductions in migraine frequency and intensity. The authors…

This paper reports molecular dynamics simulations of polyelectrolyte brushes subjected to external electric fields, focusing on how chain stiffness and salt concentration affect responses. The simulations suggest higher salt concentrations strengthen an induced opposing field from ion redistribution, which resists…

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 signals in the 0.5–20…

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. The authors conclude…

This study evaluated high-intensity pulsed electric fields (HIPEF) as a processing method to inactivate polyphenoloxidase (PPO) in strawberry juice. Using response surface methodology at a constant electric field of 35 kV/cm, the authors report strong PPO reductions across tested parameter ranges. Bipolar mode,…

This condensed-matter study investigates highly oriented pyrolytic graphite under very strong magnetic fields at low temperature. It reports a magnetic-field-induced charge density wave transition and a subsequent sign reversal of the Hall coefficient from negative to positive. The reported angular dependence…

This condensed-matter physics study examined how high magnetic fields and pressure affect magnetization, transport, and thermodynamic properties of the intermediate-valence compound YbPd. The authors report that the Yb valence state and two first-order transitions are stable up to 55 T, while increasing pressure…

This theoretical condensed-matter study examines how an electric field affects the electronic spectrum and localization in quasiperiodic chains modeled with Harper and Fibonacci potentials.
