A second coupling beam induces EIT and creates a "window" in the absorption region (red). This plot is a computer simulation of EIT in an InAs/GaAs quantum dot. Electromagnetically induced transparency (EIT) is a coherent optical nonlinearity which renders a medium transparent within a narrow spectral range around an absorption line.
2D resistivity inversion of ERT data Deployment of a permanent electrical resistivity tomography profile on a longitudinal section of an active landslide.. Electrical resistivity tomography (ERT) or electrical resistivity imaging (ERI) is a geophysical technique for imaging sub-surface structures from electrical resistivity measurements made at the surface, or by electrodes in one or more ...

1980s mortgage rate trends. At the beginning of 1980, homes in the U.S. cost a median of $63,700, according to the Department of Housing and Urban Development (HUD). By 1990, that median had risen ...
Other differences between today’s Fed and the Fed of the past include a wider target range for the benchmark fed funds rate, sometimes spanning 5 percentage points instead of the 0.25 percentage ...
where S = dP/dh is the apparent tip-sample contact stiffness at the onset of unload, ˙ is the displacement rate just before the unload, ˙ is the unloading rate, and is the true (i.e. viscosity-corrected) tip-sample contact stiffness which is related to the reduced modulus and the tip-sample contact size by the Sneddon relation.
The Fed cut its federal funds rate — the interest rate banks charge each other for short-term loans — by 0.25 percentage points, lowered the rate to a range of 4.25% to 4.5%, down from its ...
