This food science study compared freshly harvested, naturally aged, and RF-treated rice/paddy (Jhelum cultivar) to assess whether RF heating can simulate natural ageing. RF treatment reportedly induced ageing-like microstructural and functional changes similar to naturally aged rice. Reported outcomes included…

This systematic review assessed interventional preclinical and clinical studies of adjunctive non-ionizing magnetic or combined EMF therapies in dental implant surgery. Twelve studies were included, with most reporting improvements in implant stability and indicators of osteogenesis/osseointegration. Evidence for…

This in vitro study evaluated SAR and erythrocyte membrane stability during exposure to a fully textile wearable antenna at 2.41 GHz under realistic (6.3 mW) and conservative (450 mW) input power conditions. It reports 1 g average SARs of 0.5758 W/kg and 41.13 W/kg, respectively. For membrane stability at 6.3 mW,…

This study reports synthesizing hydroxyapatite and carbonate-substituted hydroxyapatite using ultrasound and microwave radiation as processing methods. The authors report that these physical factors produced calcium-deficient hydroxyapatite and B-type carbonated apatite and increased in vitro bioactivity compared…

This study compared thermosonication, pulsed electric field, and thermal processing for preserving Royal Gala apple juice and evaluated sensory attributes and quality stability during 30 days of storage at 3°C and 20°C. Thermosonication and pulsed electric field produced juices with different taste compared with…

This in vitro study tested 900-W microwave radiation regimens (3, 5, or 7 minutes) to disinfect type IV dental stone surfaces contaminated with S. aureus, E. coli, or C. albicans. The authors report that 5 and 7 minutes achieved sterilization for S. aureus, while 3 minutes did not fully sterilize; all times were…

This engineering study deposited Ga-doped ZnO thin films via radio frequency sputtering and examined how Ga content affects optoelectronic properties and electrical stability. The abstract reports non-monotonic changes in conductivity with increasing Ga content alongside degraded crystallinity, while maintaining >80%…

This engineering paper demonstrates an auto-tuning method for a high-sensitivity RF interferometer using a tunable liquid attenuator controlled by liquid volume. The authors report an effective quality factor up to 1×10 at ~5 GHz and a self-calibration/measurement process from 2 to 7.5 GHz using a methanol-water…

This engineering paper describes a fiber-based method for stable radio-frequency dissemination using a hybrid frequency modulation approach. Two RF components are transmitted simultaneously using a single laser diode, with one component used for phase fluctuation detection and the other providing a compensated stable…

This preliminary prospective clinical trial compared pulsed electromagnetic field stimulation (PEMF) and low intensity laser irradiation (LILI) as adjuncts to mandibular fracture repair assessed by clinical union and radiodensitometric bone density. Clinical outcomes (segment stability and occlusion) were…

This engineering study reports optical and electrical characteristics of photonic gel cells made from a PS-b-P2VP lamellar film and a hydrogel electrolyte on ITO glass. Applying 2 V between two facing electrodes over 30 minutes shifted the device reflectance peak from 538 nm up to 604 nm with limited bandwidth…

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 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 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 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 paper describes the design and preliminary implementation of a mobile-phone-based wireless blood pressure monitoring system that transmits data via Bluetooth and computes blood pressure and heart rate on the phone. The authors state that experiments demonstrated the device’s reliability and stability, and that…

This prospective multicenter longitudinal trial evaluated arthroscopic thermal radiofrequency capsular shrinkage for chronic ankle instability in adults who failed conservative therapy. The study reports no clinically relevant improvement in mechanical stability, but substantial and statistically significant…

This paper presents numerical methods to compute ground-state solutions of spin-1 Bose-Einstein condensates in a uniform magnetic field. The approach uses normalized gradient flow with an additional normalization condition and enforces conservation of total mass and magnetization. The authors compare numerical…
