This study evaluated pulsed radiofrequency (PRF) neuromodulation of the suprascapular nerve in 11 patients with chronic shoulder pain from adhesive capsulitis and/or rotator cuff tear. Pain (VAS) and shoulder-related quality of life/function (OSS) were assessed before treatment and monthly after PRF for up to 9…

This study evaluated a cosmetic radiofrequency device (Accent) for facial wrinkle reduction in 45 women receiving four weekly sessions. Patient satisfaction was higher at 6 months than at 1 month after treatment, and the authors suggest the approach may be effective for facial rejuvenation. The abstract emphasizes…

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 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 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 paper analyzes compressible Hall magnetohydrodynamic turbulence with an external strong guide magnetic field using signed measure analysis. In simulations varying ion skin depth to modulate the Hall term, increasing the Hall term is reported to reduce the fractal dimension of current and vorticity sheets. The…

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 engineering study reports fabrication of a biodegradable PLLA shape-memory nanocomposite incorporating surface-modified Fe3O4 nanoparticles. The composite showed improved tensile/mechanical and shape-memory properties compared with PLLA, and shape recovery could be triggered by an alternating magnetic field.…

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 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 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 engineering paper describes a mm-scale implantable device that is wirelessly powered and remotely controlled to locomote in a fluid medium. The prototype is reported to receive 500 µW from a 2 W, 1.86 GHz RF power signal at 5 cm and to support 2.5–25 Mbps data rates using asynchronous PWM on the carrier. The…

This preliminary clinical series evaluated radiofrequency-assisted recanalization of the nasolacrimal duct in adults with confirmed lower lacrimal system obstruction. The procedure used a monopolar high-frequency device at 450 kHz and 150 W under local anesthesia with sedation. At 90 days postoperatively, 81.25% of…

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 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 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…
