We illustrate how a group of symmetry transformations, which preserve the form of the n-dimensional flat Friedmann-Robertson-Walker cosmologies satisfying Einstein's equations, act in any dimension. This group relates the ...

Progesterone is a natural steroid hormone and a poor soluble drug which presents two polymorphs (forms 1 and 2). Different methods to obtain form 2 were tested and a complete solid-state characterization of both polymorphs ...

To any sequence of real numbers < a(n)>(n >= 0), we can associate another sequence < a(s)>(s >= 0), which Knuth calls its binomial transform. This transform is defined through the rule as = Bsan = Sigma(n) (-1)(n) ...

Using the fact that Miura transformation can be expressed in the form of gauge transformation connecting the KdV and mKdV equations, we discuss the derivation of the B�cklund transformation and its Miura-gauge transformation ...

In these times of pandemic, the world has witnessed the power of connectivity, and many organizations have seen the need to rethink their models and even reinvent themselves in response to this new form of global connectivity. ...
