The island of Kuai, home to the Pacific Missile Range Facility, is preparing for the first of a series of Star Wars rocket launches expected to begin early this year. The Strategic Defense Initiative plans 40 launches of the Stategic Target System (STARS) over a 10-year period. The focus of the tests appears to be weapons and sensors designed to combat

Drazin-Star and Star-Drazin Matrices
Results in Mathematics, 2020The author introduces new classes of matrices in order to solve some types of matrix equations. She defines the Drazin-star matrix and the star-Drazin matrix of \(A\in\mathbb{C}^{n\times n}\) by \((A^DAA^*)\) and \((A^*AA^D)\), respectively, where \((A^D)\) denotes the Drazin inverse of \((A)\).

The stars do not appear to be of equal brightness. About 125 BC, Hipparchus made the first classification of stars according to their brightnesses. His predecessor, Aristarchus (310–230 BC), had proved that the Sun, Moon and planets are at varying distances from the Earth, and that they do not move equally far from the Earth against a crystal sphere ...

Astronomy and Astrophysics were first treated in volume III of the 6th edition of Landolt-Bornstein in 1952, then in volumes VI/1 and VI/2 of the New Series, 1965 and 1981/82 respectively. The present volume VI/3 is a further supplementation of volume VI/1.

Star-free star and trace languages
Fundam. Informaticae, 2006Summary: The paper deals with star-free languages in free monoids and trace monoids. We introduce the notion of star-free star, fundamental for this paper, and show that the classes of star-free languages and star-free star languages coincide. Then, using this result, we obtain a general characterization of star-free trace languages, containing a ...
