BACKGROUND The number of implantable cardioverter-defibrillators (ICDs) for the prevention of sudden cardiac death is continuing to increase. Given the technological complexity of ICDs, it is of critical importance to identify and control possible harmful electromagnetic interferences between various sources of electromagnetic fields and ICDs in daily life and occupational environments. METHO...

We model alternatives for moving bulk energy, including both private costs and accounting for environmental externalities by requiring the transport system to satisfy environment health, and safety standards. In particular, we focus on the cost and environmental trade-offs between "coal by wire," mine-mouth generation with electricity transmission, and transporting the primary energy resources ...

OBJECTIVES The aim of this study was to address the prevalence of clinically assessed high-frequency hearing impairment (HFHI) and self-reported hearing impairment (SRHI) and examine the association of these hearing assessments with physical and mental functioning in African American and Caucasian women at midlife. METHODS The sample included 467 women who participated in the Michigan Functio...

Many modern theories predict that the fundamental constants depend on time, position or the local density of matter. Here we develop a spectroscopic method for pulsed beams of cold molecules, and use it to measure the frequencies of microwave transitions in CH with accuracy down to 3 Hz. By comparing these frequencies with those measured from sources of CH in the Milky Way, we test the hypothes...

For more than 12 hours beginning on January 18, 2021, continuous narrowband electrostatic emissions were observed Parker Solar Probe near 20 solar radii. The <1000 Hz frequencies well below the local ion plasma frequency. Surprisingly, consisted of wave packets with shock-like envelopes, appearing repetitively at a ~1.5 rate. This repetitiveness correlated and was in phase low frequency electro...

A dynamic blue-detuned optical dipole trap with stable (87)Rb atoms produces a differential ac Stark shift of 18 Hz in the ground state hyperfine transition, and it preserves the ground state hyperfine superpositions for a long coherence time of 180 ms. The trapped atoms undergoing microwave Rabi oscillations are sensitive to a small signal, artificially generated with a second microwave source...

In this paper, a novel wave equation for electromagnetic waves in a medium having anisotropic permittivity has been derived with the help of Maxwell’s curl equations. The x and y components of the Maxwell’s equations are written with the permittivity ( ) being a 3× 3 symmetric matrix. These equations are solved for Ex , Ey, Hx, Hy in terms of Ez , Hz, and the partial derivatives. The Z componen...

Contemporary neuroscience suggests the existence of fundamental algorithms by which all sensory transduction is translated into an intrinsic, brain-specific code. Direct stimulation of these codes within the human temporal or limbic cortices by applied electromagnetic patterns may require energy levels which are within the range of both geomagnetic activity and contemporary communication networ...
