The biophysical mechanism of magnetic fields (MFs) acting on living systems is not clear. Previous research showed that, similar to epidermal growth factor (EGF), MF exposure induced EGF receptor (EGFR) clustering and activated EGFR signaling. In this study, we investigated whether MF exposure induced the changes in physical characteristics of EGF and downstream effects of EGF and EGFR interaction...
Previous epidemiological studies suggested association between parental occupational exposure to extremely low frequency magnetic fields (ELF-MF) and risk of childhood nervous system tumors, but the results were inconsistent. We conducted a meta-analysis of case-control and cohort studies to re-evaluate this association.Relevant studies were identified by searching PubMed and Web of Science databases...
In this paper a detailed analysis of multiport vector network analyzer (VNA) measurement uncertainties due to non-ideal calibration standards for TRL calibration is presented. Using the concept of general node equations, the error correction equation is simplified by the matrix operation, thus a generalized formula for the deviations of the measured S-parameters with respect to the error terms can...
