This engineering study describes using antenna-coupled microwave radiation to enhance laser-induced breakdown spectroscopy (LIBS) emission from a Gd2O3 sample at reduced pressure. The authors report substantially increased plasma emission intensity, higher-temperature plasma, and longer emission lifetime when…

This engineering study examines how the spectral mismatch between mobile phone flash LEDs and modern display gamuts influences smartphone camera color reproduction. Using a CIECAM02-based metric and an evaluation method grounded in raw camera data and a Digital ColorChecker SG, the authors propose optimized flash LED…

This paper presents a theoretical and experimental demonstration of a photonic RF phase shifter based on a dual-parallel Mach-Zehnder modulator using a two-drive scheme. The approach aims to mitigate residual optical carrier effects and avoid a lowest-frequency limitation from an optical filter by driving the…

This occupational exposure assessment monitored surgeons during 11 surgeries using monopolar electro surgery units and measured electric and magnetic field strengths during cutting and coagulating modes. Electric fields near the cable at 10 cm were reported in the hundreds of V/m, while magnetic fields were

This paper proposes a reversible approach to tune Mie scattering resonances in random media using external low induction magnetic fields. The experimental demonstration uses ultrasound in emulsions of fluorinated ferrofluid droplets dispersed in a Bingham fluid. Magnetic-field-induced droplet deformation is reported…

This experimental study measured the electric field inside a plasma channel formed during a high-pressure nanosecond discharge in hydrogen using coherent anti-Stokes Raman scattering. The authors report root-mean-square electric field intensities up to 30 kV/cm in the plasma channel. Polarization measurements…

This laboratory study examined Rayleigh-Bénard convection in liquid gallium under varying strengths of a uniform imposed horizontal magnetic field. Using ultrasonic velocity profiling and temperature monitoring, the authors mapped a regime diagram across Ra and Q and identified five flow regimes. The results describe…

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 paper presents a theoretical model of a single ferromagnetic particle with finite coupling between its magnetic moment and particle body in a rotating magnetic field. It describes synchronous and asynchronous motion regimes, including planar motion at low frequencies and a precession regime at high frequencies,…

This study evaluated combined bipolar radiofrequency surgery of the tongue base (RFBT) with uvulopalatopharyngoplasty (UPPP) in a single session for obstructive sleep apnea, compared with UPPP alone. The combined procedure was associated with improvements in AHI, ODI, sleepiness, and snoring, while mean oxygen…

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 prospective clinical and radiological study evaluated radiofrequency kyphoplasty in 25 patients with 30 fresh osteoporotic vertebral fractures. Pain scores decreased significantly postoperatively and at 3 months, and vertebral height/kyphosis measures improved and remained stable at follow-up. The authors report…

This engineering-focused study evaluates pulsed electric field (PEF)-assisted, solvent-free modification of pectin from sugar beet pulp. The authors report that degree of esterification increased with greater PEF intensity and energy input, with supporting evidence from FT-IR, X-ray diffraction, and NMR. Modified…

This in vitro experimental study examined how an AC electric field influences actin filament (F-actin) movement on a myosin-coated substrate. The authors report that the field induces electro-orientation torque that aligns movement perpendicular toward electrode edges, with alignment increasing with field strength.…

This observational study followed 36 patients for 2 years after temperature-controlled radiofrequency tissue volume reduction for turbinate hypertrophy. Patients reported significantly lower VAS symptom scores (nasal obstruction, headache, rhinorrhoea, anosmia) after treatment compared with baseline. Urban residence…

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…
