A Metric for Automatic Hole Characterization

A CHARACTERIZATION FOR METRIC TWO-DIMENSIONAL GRAPHS AND THEIR ENUMERATION

‎The textit{metric dimension} of a connected graph $G$ is the minimum number of vertices in a subset $B$ of $G$ such that all other vertices are uniquely determined by their distances to the vertices in $B$‎. ‎In this case‎, ‎$B$ is called a textit{metric basis} for $G$‎. ‎The textit{basic distance} of a metric two dimensional graph $G$ is the distance between the elements of $B$‎. ‎Givi...

Isolation and Characterization of the Progenitor Cells From the Blastema Tissue Formed at Experimentally-Created Rabbit Ear Hole

  Objective(s): Throughout evolution, mammalians have increasingly lost their ability to regenerate structures however rabbits are exceptional since they develop a blastema in their ear wound for regeneration purposes. Blastema consists of a group of undifferentiated cells capable of dividing and differentiating into the ear tissue. The objective of the present study is to isolate, culture expa...

A Characterization of the Infinitesimal Conformal Transformations on Tangent Bundles

Two Metrics unsuitable for Black Holes embedded in Expanding Universe

How to describe a black hole embedded in an expanding universe is an important topic. Many models about this issue are suggested by assuming that the metric is a conformal transformation of the Schwarzschild metric or of the isotropic black hole metric. In the paper, it is shown that the two metrics are not suitable for describing a black hole embedded in an expanding universe because of the si...

A New Action-Derived Form of The Black Hole Metric

Several different but equivalent forms of the spherical black hole (Schwarzschild) are known, as well as several derivations. Here a novel form is derived through the power of the action formalism. The method generalizes to any spherical black hole or brane, and the charged hole case (Reissner-Nordström) is worked out in detail. To Eitan Aharoni, my friend ever since the 7th grade, who always e...
