This engineering simulation study models colloidal particle transport and deposition in a membrane filtration channel at a particle volume fraction of 10%. The model couples a dynamically updating crossflow velocity field with particle-particle and particle-membrane interaction potentials (electrostatic double layer…

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 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 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 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 article describes a surgical technique for arthroscopic capsular release in adhesive capsulitis using a flexible hip arthroscopy radiofrequency ablator. The authors present it as a creative approach intended to improve safety and precision in a procedure that can be technically challenging. The abstract does not…

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 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 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 engineering materials study reports fabrication and characterization of nanocomposite dielectrics in a PbO-BaO-Na2O-Nb2O5-SiO2 glass-ceramic system. X-ray diffraction and microstructural observations describe temperature-dependent phase formation with nanometer-sized crystallites dispersed in a glass matrix. The…

This engineering study investigates a plasmonic nanostructure composed of a spherical metallic nanoshell with a small metallic nanoparticle (“nanoknob”) on its surface. It reports tunable plasmon resonance behavior driven by nanoshell properties and localized/enhanced electromagnetic fields near the nanoknob under…

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 case-control study measured electric field intensity and magnetic flux density in high voltage substations and estimated workers' ELF-EMF exposure over a shift. Sleep quality was assessed using the PSQI in 67 exposed workers and 110 controls. The study reports no statistically significant difference in overall…

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 theoretical/physics study analyzes the spectrum of electron-phonon complexes in monolayer graphene in a perpendicular quantizing magnetic field. It reports that near the threshold of optical phonon emission, standard perturbation theory fails for calculating the scattering amplitude. The authors describe new…

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 paper proposes that Pb nanowires created by repeated indentation of a Pb tip on a Pb substrate may exhibit topological superconducting properties in an external magnetic field. The authors analyzed conductance curves from different nanowires and report that, in a few cases, the critical current shows a peculiar…
