This materials study used optical second harmonic generation to detect electric field-induced structural changes at Pt/Fe-doped SrTiO3 anode interfaces. Reduced crystals showed steadily increasing susceptibility with increasing negative voltage, interpreted as electrostriction-related bond distortions. Oxidized…

This materials study examined how growth rate and an external magnetic field affect microstructure and properties in directionally solidified Ag-Cu eutectic alloys. The lamellar spacing followed the Jackson-Hunt model with a reported constant of 5.8 µm³/s. Increasing magnetic field tilted eutectic growth and…

This review-style article discusses gerontechnologies—mobile applications on smartphones/tablets and remote monitoring systems—for outpatient symptom monitoring and self-care management in older adults with heart failure. It frames these tools as potentially cost-effective and accessible when designed for older…

This prospective, randomized, single-blind study compared monopolar versus bipolar radiofrequency surgery for inferior turbinate hypertrophy in 71 patients. Over 6 months, long-term symptom outcomes did not significantly differ between groups. Monopolar radiofrequency showed earlier symptom improvement and less…

This pilot randomized study evaluated systemic extremely low-frequency magnetic field (ELF-MF) therapy versus sham in 37 women with fibromyalgia using a crossover sequence. The abstract reports significant short-term reductions in pain and improvements in fibromyalgia-related symptom and function questionnaires…

This engineering study investigated RF-induced power deposition near straight insulated leads in an MRI context under different incident electric field profiles. Using 3-D electromagnetic simulations, the authors compared simulation-derived power deposition with implant model predictions. For the setups examined,…

This conference paper describes a peri-implantitis therapy using radio frequency electric current and presents numerical simulations alongside referenced clinical evidence. The abstract reports 81% successful treatment across 66 implants in 46 patients. FEM modeling suggests current preferentially concentrates in…

This engineering paper reports a prototype wearable patient-monitoring device that transmits vital-sign measurements via Bluetooth LE during MRI. Across 7 MRI acquisitions (25 minutes total), the authors report no Bluetooth packet loss, increased PPG noise during MRI, and no effect on temperature/humidity readings.…

This engineering study investigated RF-induced power deposition from insulated leads of different lengths positioned near two surrounding tissues. The authors report that both the electromagnetic lead models and the resulting power deposition depended strongly on the electrical properties of both tissues. Using a…

This conference paper describes an automated method for ABO and Rh-D blood typing using images captured by low-cost mobile phones of a fabric strip rapid diagnostic test. The approach applies morphological image processing steps including noise reduction, range filtering, and empirically derived heuristics to…

This computational study used finite element modeling to estimate the electric field distribution in the brain during tDCS for two electrode montages targeting the left DLPFC. It systematically varied isotropic tissue conductivity profiles to assess sensitivity of predicted E-field magnitude and components in the…

This engineering-focused study examined how inter-electrode distance in transcutaneous spinal direct current stimulation (tsDCS) affects electric field distribution in the lumbar and sacral spinal cord. Peak E-field magnitudes occurred in the lumbo-sacral region for all configurations. Larger electrode separations…

This engineering-focused conference paper characterizes thrombus stiffening after radio frequency (rf) electric current treatment in the context of intra-arterial mechanical thrombectomy. The abstract reports thrombus stiffness increased by more than eightfold after rf treatment, attributed to increased crosslinking.…

This conference paper reports an engineering approach to convert wireless microwave power into near-infrared light using a miniaturized, wirelessly powered laser. The device is described as millimeter-scale and capable of being powered through >1 cm of tissue. The abstract focuses on enabling in vivo activation of…

This conference paper describes the design and simulation of coil geometries intended to produce a highly uniform magnetic field for scleral search coil eye-movement recordings without restricting head motion. The authors built a large (2.2 m per side) coil frame and compared measured magnetic flux density to…

This review assessed surgical and procedural case logbook smartphone applications available in major app stores. Of 2,740 apps screened, 16 were relevant and 11 were suitable for critical review, with reported variation in app size and cost. The authors conclude that current mobile apps can efficiently replace…

This single-institution cohort analysis compared radiofrequency microtenotomy with plantar fasciotomy for recalcitrant plantar fasciitis, including a group receiving both procedures. Patient-reported outcomes (SF-36, AOFAS) and satisfaction/expectations were reportedly similar across procedures at 6 months and 1…

This exposure assessment study measured personal and bedroom extremely low-frequency magnetic field (ELF-MF) exposures in 172 children (5–13 years) in Switzerland and Italy. Geometric mean exposures were low on average (0.04 μT personal; 0.05 μT bedroom), but were higher among children living within 100 m of a…

This engineering study demonstrates magnetophoretic track designs that transport single magnetized beads and magnetically labeled single cells in a 3D time-varying magnetic field. A vertical field bias is reported to reduce particle clustering but necessitates redesigned track geometries with alternating curvature.…

This laboratory/analytical study examined how sample matrix affects sample sweeping in micellar electrokinetic chromatography under an inhomogeneous electric field. It reports strong focusing for hydrophobic cationic analytes when the sample matrix conductivity is much higher than the BGE, even with low surfactant…

This mouse study examined chronic smartphone electromagnetic radiation exposure and its effects on spatial working memory and hippocampal progenitor cell proliferation. The authors report no significant differences in Y-maze spontaneous alternation or BrdU-labeled progenitor proliferation after exposure, but…

This engineering paper presents an experimentally validated wearable personal exposimeter system for RF-EMF exposure monitoring, motivated by increasing wireless applications. It uses a distributed measurement approach and integrates inertial sensors to capture activity and posture during measurements. The system is…
