Ghost imaging is a transverse imaging technique that relies on the correlation between a pair of light fields, one that has interacted with the object to be imaged and one that has not. Most ghost imaging experiments have been performed in transmission. and virtually all ghost imaging theory has addressed the transmissive case. Yet stand-off sensing applications require that the object be image...

In the context of deductive program verification, ghost code is part of the program that is added for the purpose of specification. Ghost code must not interfere with regular code, in the sense that it can be erased without any observable difference in the program outcome. In particular, ghost data cannot participate in regular computations and ghost code cannot mutate regular data or diverge. ...

The facts of the human body, evolutionary, physiological, social, and systemic, as experienced and symbolized (often differently) by every human, necessarily set the standards, and the limits, of human minds, and of theories about them. Following Turner (1994), who conjures the ghost of Plato conjuring the ghost of Socrates conjuring the ghost of Protagoras, we may call (1) Protagoras’s Principle:

On (b, c)-system at finite temperature in thermo field approach Abstract We construct the finite temperature field theory of the two-dimensional ghost-antighost system within the framework of thermo field theory.

We demonstrate that a Hermitian matrix model can be derived from level truncated open string field theory with Chan-Paton factors. The Hermitian matrix is coupled with a scalar and U(N) vectors which are responsible for the D-brane at the tachyon vacuum. Effective potential for the scalar is evaluated both for finite and large N. Increase of potential height is observed in both cases. The large...

Terrestrial laser scanning (TLS) data makes possible to directly characterize the three-dimensional (3D) distribution of canopy foliage elements. The scanned edges of these elements may result in incorrectly point measurements (i.e., “ghost points”) impacting the quality of point cloud data. Therefore, estimation of the ghost points’ spatial visibilities, measurement of their characteristics an...

One of the most surprising consequences of quantum mechanics is the nonlocal correlation of a multi-particle system observable in joint-detection of distant particle-detectors. Ghost imaging is one of such phenomena. Taking a photograph of an object, traditionally, we need to face a camera to the object. But with ghost imaging, we can image the object by pointing a CCD camera towards the light ...

The gluonic ghost pole has been instrumental in explaining the mass of the η and providing a plausible explanation for solving the spin crisis. We show that it also plays an important role in the description of photoand electroproduction of vector mesons at low energy and high momentum transfers. We calculate the axial ghost pole contribution to φ meson electromagnetic production in a model, wh...
