Comparative Analysis of Five XML Query Languages
Angela Bonifati, Stefano Ceri
XML is becoming the most relevant new standard for data representation and exchange on the WWW. Novel languages for extracting and restructuring the XML content have been proposed,…
A Model for the Self-Organization of Microtubules Driven by Molecular Motors
B. Bassetti, M. Cosentino Lagomarsino, P. Jona
We propose a two-dimensional model for the organization of stabilized microtubules driven by molecular motors in an unconfined geometry. In this model two kinds of dynamics are com…
Quantum stochastic models of two-level atoms and electromagnetic cross sections
Alberto Barchielli, Giancarlo Lupieri
Quantum stochastic differential equations have been used to describe the dynamics of an atom interacting with the electromagnetic field via absorption/emission processes. Here, by…
Kerr-Schild Approach to the Boosted Kerr Solution
Alexander Burinskii, Giulio Magli
Using a complex representation of the Debney-Kerr-Schild (DKS) solutions and the Kerr theorem we analyze the boosted Kerr geometries and give the exact and explicit expressions for…
Gravitational collapse of fluid bodies and cosmic censorship: analytic insights
Sanjay Jhingan, Giulio Magli
The present analytical understanding on the nature of the singularities which form at the endstate of gravitational collapse of massive fluid bodies ("stars") is reviewed. Special…
Black holes vs. naked singularities formation in collapsing Einstein's clusters
S. Jhingan, G. Magli
Non-static, spherically symmetric clusters of counter-rotating particles, of the type first introduced by Einstein, are analysed here. The initial data space can be parameterized i…
