This engineering study addresses inter-cell interference in LTE networks as a driver of packet loss between base stations and mobile stations. It examines Soft Frequency Reuse (SFR) and implements a new hybrid frequency reuse method with greater total system bandwidth than SFR while keeping per-cell bandwidth the…

This study evaluated whether fusing delayed enhancement MRI (DE-MRI) with magnetic resonance angiography (MRA) improves visualization of radiofrequency ablation lesions after pulmonary vein isolation. Eighteen atrial fibrillation ablation patients underwent both imaging approaches, and two observers scored lesion…

This feasibility study evaluated whether delayed-enhancement MRI (DE-MRI) using commercially available tools could visualize radiofrequency ablation lesions in Japanese patients with atrial fibrillation. Of 15 scans, 3 were uninterpretable due to low image quality, and lesions were visualized in 8 of the remaining 12…

This engineering study evaluates mechanical hoop strain in a YBCO coated-conductor double-pancake coil intended for a high-field HTS insert in an NMR magnet. The authors present experimental strain-gauge measurements and analytical stress/strain calculations for a coil operated with and without a stainless steel…

This engineering/food science study measured dielectric constant (ε'), dielectric loss factor (ε″), and power penetration depth in beef and gravy preparations across 27–1,800 MHz and 20–130 °C. The dielectric properties generally decreased with increasing frequency, and penetration depth decreased with increasing…

This in vitro study examined whether electromagnetic fields (EMFs) influence chondrogenic differentiation of bovine mesenchymal stem cell pellets, with and without the inflammatory cytokine IL-1β. The authors report EMFs had limited effects on chondrogenesis in the absence of inflammation, but in the presence of…

This cross-sectional study measured ELF magnetic flux density in a petrochemical complex substation environment and assessed workers' sleep quality (PSQI) and general health (GHQ). It reports significant differences between case and control groups, with more sleep disorder and poorer health status in the case group.…

This randomized controlled trial compared postoperative pulsed electromagnetic field therapy (I-ONE) versus control in 33 patients undergoing total knee arthroplasty. The treated group reported significantly better pain, swelling, and functional scores at 1 month, with lower pain still present at 6 months. At 3…

This double-blind randomized placebo-controlled trial evaluated pulsed electromagnetic field (PEMF) therapy followed by a standardized shoulder strengthening exercise program in adults with shoulder impingement syndrome (N=56). The active PEMF group improved in pain and function from baseline across follow-ups, while…

This animal study evaluated whether daily pulsed electromagnetic field (PEMF) treatments improve delayed fracture healing in skeletally mature ovariectomized (OVX) rats. By 6 weeks, PEMF-treated rats showed improved hard callus elastic modulus and radiographic evidence of better callus bridging compared with sham…

This food science study assessed how UV irradiation, pulsed electric field, hot water dip, and ethanol vapour treatments affected mung bean sprout quality and storage life at room and low temperatures. The abstract reports minimal effects on sprout growth metrics, with ethanol suppressing length/weight, hot water dip…

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/materials study examined how RF magnetron sputtering power affects the structural and optical properties of In2S3 thin films intended as a CdS buffer substitute in CIGS solar cells. Films deposited at 60–120 W were characterized using XRD, AFM, EDS, and UV-visible spectrophotometry. The films were…
