Abstract We study for the first time propagation of packets plane waves Maxwell free field in de Sitter expanding universe as detected by an observer staying at rest his proper frame with physical Sitter–Painlevé coordinates. This observes accelerate wave packet along to a null geodesic, laying out severe exponential decay and moderate dispersion, increasing exponentially during propagation. Th...

The mirror constitutes a significant image that recurs multiple times in Heart Is Lonely Hunter, and it is mainly associated with Mick Kelly Biff Brannon, who are reckoned the novel grotesques terms of sexuality. This article does not consider as something merely reflecting subject front it, but media occasions self-examination self-reconstitution subject. It superimposes Michel Foucault’s conc...

Conventional mirrors convert right-handed circularly polarized waves (RCP) into left-handed circularly polarized waves (LCP) and vice versa, see Fig. 1(a-c). Here we demonstrate a novel type of chiral mirror that will reflect one circular polarization without changing its handedness, while absorbing waves of the opposite handedness, see Fig. 1(d-f). This functionality, which fundamentally relie...

We consider the cooperative spontaneous emission of a system two identical atoms, interacting with electromagnetic field in vacuum state and presence an oscillating mirror. assume that one ground other excited state, are prepared correlated (symmetric or antisymmetric) {\em Bell}-type state. also suppose perfectly reflecting plate oscillates adiabatically, modes satisfying boundary conditions a...

Recently proposed low scale quantum gravity scenario is expected to have a significant impact on the Mirror World hypothesis. Some aspects of this influence is investigated here, assuming that the fundamental gravity scale is near a TeV. It is shown that future colliders will be capable to produce the mirror matter, but an experimental signature, which will distinguish such events from the back...

A new class of visuomotor neuron has been recently discovered in the monkey's premotor cortex: mirror neurons. These neurons respond both when a particular action is performed by the recorded monkey and when the same action, performed by another individual, is observed. Mirror neurons appear to form a cortical system matching observation and execution of goal-related motor actions. Experimental...

Low-voltage cascode current mirrors are reviewed with respect to the design limitations imposed if all transistors in the mirror are required to operate in the saturation region. It is found that both a lower limit and an upper limit exist for the cascode transistor bias voltage. Further, the use of a signal dependent cascode bias voltage is discussed and a selfbiased cascode configuration is p...

Mirror neurons and canonical neurons are two classes of visuomotor neurons that are activated by different visual stimuli (Rizzolatti and Kalaska, 2012). Mirror neurons respond to a biological effector interacting with an object (Gallese et al., 1996), suggesting their role in action recognition, while canonical neurons respond to the presentation of a graspable object (Murata et al., 1997), an...

We describe an atom interferometer to study the coherence of atoms reflected from an evanescent wave mirror. The interferometer is sensitive to the loss of phase coherence induced by the defects in the mirror. The results are consistent with and complementary to recent measurements of specular reflection.
