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 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 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 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 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 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 physics study analyzes circular wave packets in high Rydberg states produced by applying a pulsed electric field to extreme Stark states. It reports a position-dependent energy gradient that creates a correlation between principal quantum number and spatial coordinate, which appears insensitive to the initial…

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 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 engineering study investigated factors affecting electro-dewatering of activated sludge under a horizontal applied electric field. It reports optimal performance without altering sludge pH or conductivity and finds that CPAM conditioning improves and accelerates dewatering. The authors provide operating…

This study measured atmospheric VOCs at the Gongga Mountain base station using weekly samples collected in 2007 and analyzed by preconcentration plus GC-MS. It reports mean concentrations of TVOCs and NMHCs, describes VOC composition, and uses PCA-based receptor modeling to attribute sources. The authors report…
