Methodologically solid and analytically rigorous: the evaluations of our systematic review on RF-EMF and animal cancer are reliable

Research RF Safe Research Library Jan 1, 2025

No abstract is available in the provided material. From the title, the article appears to defend or affirm the methodological rigor and reliability of evaluations in the authors' systematic review on RF-EMF exposure and animal cancer. Specific results regarding carcinogenic effects are not stated in the provided text.

[Electromagnetic field in the environment - estimation methods and monitoring].

Research RF Safe Research Library Jan 1, 2019

This paper discusses the legal context for environmental EMF measurements and describes methods for estimating EMF intensity from multiple sources, particularly cellular base stations. It presents an engineering concept for mobile EMF monitoring and reports verification testing of the measurement setup. Field…

The Validity and Reliability of the Persian Version Test of Mobile Phone Dependency (TMD).

Research RF Safe Research Library Jan 1, 2015

This cross-sectional study developed and validated a Persian version of the Test of Mobile Phone Dependency (TMD) in 350 Tehran university students. Factor analysis identified three factors and the scale showed high internal consistency and moderate test-retest reliability. The authors report a best cut-off point of…

A novel mobile phone application to assess nutrition environment measures in low- and middle-income countries.

Research RF Safe Research Library Jan 1, 2014

This study describes the design, pilot testing, and validation of a mobile phone application version of the Guatemala NEMS-S supermarket survey. In a single supermarket, the app demonstrated high interrater reliability relative to the paper version and good test-retest reliability. The app also reduced survey…

Passive tracking of linac clinical flow using radiofrequency identification technology.

Research RF Safe Research Library Jan 1, 2014

This study reports implementation of a passive RFID system to passively track patient flow in a radiation therapy clinic using readers/antennae in linac vault areas. Across 4302 treatment fractions from 144 patients, the system achieved about 70% read reliability and enabled comparison of median in-vault treatment…

Evaluation of the packaging and encapsulation reliability in fully integrated, fully wireless 100 channel Utah Slant Electrode Array (USEA): Implications for long term functionality.

Research RF Safe Research Library Jan 1, 2012

This engineering study evaluated long-term encapsulation and packaging reliability of a fully wireless 100-channel Utah Slant Electrode Array system in vitro. The device was soaked in PBS for over 12 months while being wirelessly powered/configured at 2.765 MHz and transmitting an FSK-modulated 900 MHz RF signal. The…

[Realization of mobile phone based wireless blood pressure monitoring system and its preliminary implementation].

Research RF Safe Research Library Jan 1, 2011

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…

Historical building monitoring using an energy-efficient scalable wireless sensor network architecture.

Research RF Safe Research Library Jan 1, 2011

This engineering paper describes low-power wireless sensor nodes and a cluster-based dynamic-tree hierarchical WSN architecture for monitoring historical buildings and wooden artifacts for early pest detection. The authors report simulation and demonstration results indicating improved scalability and reliability…

Magnetic field distribution and signal decay in functional mri in very high fields (up to 9.4 T) using monte carlo diffusion modeling.

Research RF Safe Research Library Jan 1, 2007

This paper models extravascular MRI signal decay (R2/R2*) as a function of blood oxygenation, vessel geometry, and magnetic field strength up to 9.4 T using Monte Carlo diffusion simulations. It reports different vessel-size dependencies for Hahn-spin-echo versus gradient-recalled-echo relaxation across field…
