Converging Luminosity in Column‐Sprite Filaments

The luminosity bias relation from filaments in the Sloan Digital Sky Survey Data Release Four

We compare quantitative estimates of the filamentarity of the galaxy distribution in seven nearly two dimensional sections from the survey against the predictions of ΛCDM N-body simulations. The filamentarity of the actual galaxy distribution is known to be luminosity dependent. It is also known that the filamentarity of the simulated galaxy distribution is highly sensitive to the bias, and the...

Converging Hands or Converging Minds?

Interlocutors sometimes repeat each other’s representational hand gestures. We investigated if this is a case of direct mimicry of form, or whether perceiving a gesture gives rise to a semantic representation, which subsequently informs gesture production. For this we used an interactive route description task, in which a confederate’s gestures indicated the route in either the vertical or the ...

Cosmic Walls and Filaments Formation in Modied Chaplygin Gas Cosmology

We want to study the perturbation growth of an initial seed of an ellipsoidal shape in Top-Hat collapse model of the structure formation in the Modied Chaplygin gas cosmology. Considering reasonable values of the constants and the parameters of the model under study, we can show that a very small deviation from spherical symmetry (ellipsoidal geometry) in the initial seed leads to a nal highly ...

NBIC, THE CONVERGING TECHNOLOGIES

Shockwaves in Converging Geometries

Plate impact experiments are a powerful tool in equation of state (EOS) development, but are inherently limited by the range of impact velocities accessible to the gun. In an effort to dramatically increase the range of pressures which can be studied with available impact velocities, a new experimental technique is being developed. The possibility of using a confined converging target to focus ...
