Electrical conductivity of tissue at frequencies below 1 MHz.

A two-pronged approach, review and measurement, has been adopted to characterize the conductivity of tissues at frequencies below 1 MHz. The review covers data published in the last decade and earlier data not included in recent reviews. The measurements were carried out on pig tissue, in vivo, and pig body fluids in vitro. Conductivity data have been obtained for skeletal and myocardial muscle...

Tests of Gravity at the 100 Micron Scale and Below

Experimental limits allow for new forces in nature millions of times stronger than gravity at distance scales resolvable to the unaided eye, and trillions of times stronger than gravity at scales accessible to scanning probe microscopy. Recent theoretical work has led to specific predictions of new physics in these regimes, including possible signatures of extra spacetime dimensions. This prese...

DC component analysis at LWA1

After the newly constructed LEDA outriggers at LWA1 became operational Hank Tillman and Steve Ellingson performed TBN observations on September 5, 2013. They only looked at the 5 outriggers and performed dipole-dipole correlations for those baselines. They noted discrepancies in the magnitude and phase of the correlation products going from baseline to baseline. More importantly they reported a...
