Napoleon Polygons
An n-gon is called Napoleon if the centers of the regular ngons erected outwardly on its sides are vertices of a regular n-gon. In this note we obtain a new geometric characterization of Napoleon ngons and give a new proof of the well-known theorem of Barlotti Greber ([1], [3]) that an n-gon is Napoleon if and only if it is affine regular. Moreover, we generalize this theorem by obtaining an an...

Plasmapheresis, which is defined as the removal of plasma, can be either "adjusted plasma" or “exchange of plasma”.

During the past 50 years, growth and differentiation molecules have been identified and shown to contribute importantly to many different biological functions. One of these, the recently discovered neuregulin (NRG) and the associated erbB receptors were first found to be important for differentiation of the peripheral nervous system, where they direct the differentiation of Schwann cells from n...

Embryos of different species of vertebrate share a common organisation and often look similar. Adult differences among species become more apparent through divergence at later stages. Some authors have suggested that members of most or all vertebrate clades pass through a virtually identical, conserved stage. This idea was promoted by Haeckel, and has recently been revived in the context of cla...

The main purpose of the present meta-analysis was to examine the criterion-related validity of the 20-m shuttle run test for estimating cardiorespiratory fitness. Relevant studies were searched from twelve electronic databases up to December 2014, as well as from several alternative modes of searching. The Hunter-Schmidt’s psychometric meta-analysis approach was conducted to estimate the popula...
