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 paper describes development and testing of a Wi-Fi–enabled tele-localisation prototype for radiotherapy field localisation using a personal digital assistant (PDA). Trial tests on 30 subjects across multiple treatment regions reported localisation times under 1.5 minutes and similar transmission speeds across…

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…

This experimental animal study evaluated whether a radiofrequency method could induce thrombosis within an abdominal aortic aneurysm sac to potentially prevent endoleaks after endovascular repair. Six dogs received radiofrequency blood clotting of the sac and then stent-grafting, compared with a historical group of…

This engineering paper presents an intraoral version of the Tongue Drive System (iTDS) built into a dental retainer. It uses four 3-axis magnetoresistive sensors to detect tongue motion and transmits digitized data wirelessly via a dual-band 27/432 MHz transmitter, with configuration updates via a 13.56 MHz inductive…

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 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 engineering paper describes a wireless implementation of a near-infrared profiling sensor using multiple sensor nodes and a base station for data preprocessing and realignment. It reports an enhanced classification approach using a back-propagation neural network to categorize objects as human, animal, or…

This experimental study investigated evaporation of pure water placed at different simulated gravity positions within a superconducting magnet producing a large gradient magnetic field. Water evaporation was reported to be faster in the magnetic field than without the field, and the amount evaporated varied by…

This animal and in vitro study evaluated nanosecond pulsed electric fields (nsPEF) as a nonchemical method to activate platelet-rich plasma (PRP) for cardioprotection. In rabbits undergoing brief coronary occlusion followed by reperfusion, PRP injection into ischemic myocardium was associated with reduced infarct…

This study compared two non-invasive acupoint stimulation methods—TEAS and PEMF—as alternatives to manual acupuncture for recovery from exercise-induced muscle fatigue. Using 2 Hz stimulation (PEMF magnetic flux 30.92 mT), the authors report faster recovery of EMG median frequency and improved peak torque recovery in…

This paper presents a theoretical description of nonequilibrium dynamics in a three-dimensional Fermi-Hubbard model driven by an external electric field. The authors report direction-dependent damping of Bloch oscillations and the emergence of a long-lived transient prethermalized state over a broad range of field…

This study examines how spatial inhomogeneity affects a two-dimensional noncentrosymmetric superconductor in an in-plane magnetic field, motivated by LaAlO3-SrTiO3 interfaces. The authors report that spatial variation of Rashba spin-orbit coupling can generate local magnetic flux patterns through a field-induced…

This Letter presents a method for constructing solar-wind-like magnetic fields that are nearly constant in magnitude, divergence-free, and match any specified fluctuation power spectrum. The approach selects relative phases between two polarizations per wave vector to minimize variance in field magnitude while…
