Topological indices in Random Spiro Chains [PDF]
arXiv, 2022 In this paper, we study topological indices in random spiro chains via a martingale approach. In which their explicit analytical expressions of the exact distribution, expected value and variance are obtained. As n goes to infinity, the asymptotic normality of topological indices of a random spiro chain is established through the Martingale Central ...

The Spiros imaging software for the Integral SPI spectrometer [PDF]
Astron.Astrophys.411:L123-L126,2003, 2003 A key tool in the package of software available for the analysis of data from the SPI spectrometer of Integral is the SPIROS system developed at the University of Birmingham. Although intended primarily for the analysis of point sources and for the extraction of spectral information, SPIROS has many additional capabilities.

Ligand-biased ensemble receptor docking (LigBEnD): a hybrid ligand/receptor structure-based approach. [PDF]
, 2017 Ligand docking to flexible protein molecules can be efficiently carried out through ensemble docking to multiple protein conformations, either from experimental X-ray structures or from in silico simulations.

Global Hyperbolicity of Sliced Spaces [PDF]
Gen.Rel.Grav. 36 (2004) 1183-1188, 2003 We show that for generic sliced spacetimes global hyperbolicity is equivalent to space completeness under the assumption that the lapse, shift and spatial metric are uniformly bounded. This leads us to the conclusion that simple sliced spaces are timelike and null geodesically complete if and only if space is a complete Riemannian manifold.

Modern Approaches to Cosmological Singularities [PDF]
J.Phys.Conf.Ser. 8 (2005) 150, 2005 We review recent work and present new examples about the character of singularities in globally and regularly hyperbolic, isotropic universes. These include recent singular relativistic models, tachyonic and phantom universes as well as inflationary cosmologies.
