This study evaluated mobile phone use as a tool to improve cancer care follow-up and communication in a low-resource Nigerian setting. Among 1176 oncology patients, sustained follow-up at 24 months was reported as much higher in those receiving the phone intervention than in those who did not. Patients also reported…

This paper describes an engineering/clinical tool development effort: the Robotic EndoLaryngeal Flexible (Robo-ELF) Scope System for manipulating flexible endoscopes in laryngeal surgery. The system includes multiple degrees of freedom, a passive positioning arm, and a custom joystick controller enabling one-handed…

This study investigates instrumentation and procedures to assess electromagnetic exposure from compact fluorescent lamps (CFLs) by measuring both incident and induced fields in the 10 kHz–1 MHz range. For some CFLs, incident electric fields exceeded ICNIRP reference levels at close distances, but induced fields were…

This experimental and clinical study compared two umbrella-shaped expandable radiofrequency ablation electrodes (SuperSlim vs CoAccess) across different ablation algorithms. In ex vivo bovine liver, CoAccess generally produced larger ablation areas and required longer ablation times than SuperSlim, with no…

This engineering study describes a handheld microfluidic preconcentrator that uses dielectrophoresis generated by circular microelectrodes with a stepping electric field. Numerical simulations were used to illustrate the electric-field concept. In experiments, HeLa cells were reportedly preconcentrated within 160…

This study evaluated pulsed electric fields (PEF) as a pasteurization method for raw skim and whole milk across multiple treatment intensities and storage conditions. The abstract reports only minor changes in physicochemical properties and small decreases in some composition measures under stronger treatments.…

This engineering/materials study describes a template-free solution-phase method to synthesize well-aligned nickel nanochains under applied magnetic fields. The authors report that nanochain size and morphology can be tuned by reaction temperature and magnetic field conditions, and explain alignment via magnetic…

This paper describes an engineering method for nucleating nanocrystalline carbon films on monocrystalline silicon using a combination of microwave and radio frequency plasma-assisted chemical vapor deposition. The approach is demonstrated via deposition of nanocrystalline diamond after a seeding step and growth of…

This pre/post clinical study evaluated radiofrequency-assisted uvulopalatopharyngoplasty for snoring using polysomnography before and after surgery in 22 patients. The abstract reports a statistically significant postoperative reduction in snoring, with most patients showing decreased snoring index. The work concerns…

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 retrospective cross-sectional study evaluated pulsed radiofrequency (PRF) for chronic pain in patients who did not respond to conventional treatment. Across 24 patients treated at different anatomical regions, 66.7% reportedly achieved at least a 50% reduction in VAS pain scores over a mean follow-up of 8.5…

This paper addresses heat dissipation mechanisms of magnetic nanoparticles used in targeted hyperthermia under large alternating magnetic fields. Using numerical comparisons, it reports additional features in relaxation loss for rotatable superparamagnetic nanoparticles and field-induced formation of oriented…

This engineering paper proposes a control method for a photo-electromagnetic field (EMF)-based ammonia gas sensor that uses a wireless network and adjusts illumination light intensity. It reports that measurement error is minimized over 3800 ppm ammonia when the concentration corresponds to an optimal illumination…

This engineering study develops and experimentally evaluates a fuzzy-logic method for locating mobile robots in an intelligent space using wireless sensor networks. Localization relies on inter-node range measurements estimated from RF signal strength attenuation, which the authors describe as noisy and unreliable.…

This engineering paper describes a system implementation for interoperation between a 915 MHz UHF RFID reader and a TCP/IP gateway device. The architecture uses wired communication between the TCP/IP device and RFID reader, and wireless ZigBee (IEEE 802.15.4) links to an end-device/coordinator. Web-based tests are…

This engineering study describes an experimental setup using a small electret condenser microphone connected to a notebook/PC to detect extremely low frequency signals. Using a small air cell made from a drilled DVD plate with a speaker and microphone on opposite sides, the microphone captured signals in the 0.5–20…

This university-based pilot study evaluated whether two-way SMS text messaging could be used to collect situational assessment data during simulated public health critical events. Among 63 enrolled students, 76.7% of prompted SMS surveys were completed, and most responses were returned quickly. The authors conclude…

This clinical study evaluated micro-plasma radio frequency treatment for facial acne scars in 24 patients. Patients received 3–5 treatments and were assessed using photographs before and 2 months after treatment. The authors report an overall improvement rate of 83.33% and conclude the technique is effective.

This article reports an engineering implementation of a wireless sensor network-based remote water-level monitoring system. The system includes field sensors, a base station, a data center, and a web publishing module, and is described as providing real-time monitoring and anti-jamming capability. The authors state…
