The new measurement of the muon’s anomalous magnetic moment implies an improved model–independent limit on the scale of muon substructure, Λμ ∼ 2TeV. ∗[email protected]

Determining the large-scale structure of galaxy distribution in the local universe is currently an active research area in cosmology. Features called superclusters, which are global overdensities of galaxies, are of particular interest. Superclusters are comprised of a collection of galaxy clusters, which are smaller-scale and more dense regions of galaxies, along with the regions between these...

The quark mixing matrix with manifest Cabibbo substructure and an angle of the unitarity triangle as one of its parameters Abstract The quark mixing matrix is parameterised such that its " Cabibbo substructure " is emphasised. One can choose one of the parameters to be an arbitrarily chosen angle of the unitarity triangle, for example the angle β (also called Φ 1).

In this paper we consider finding solutions for problems represented using AND/OR graphs, which contain tasks that can fail when executed. In our setting each node represent an atomic task which is associated with a failure probability and a rollback penalty. This paper reports the following contributions (a) an algorithm for finding the optimal ordering of the atomic tasks in a given solution ...

The Gauß–Manin connection is an extra structure on the de Rham cohomology of any algebraic variety, ∇ : H dR/k −→ Ωk ⊗k H dR/k (its definition will appear below). If one believes the Hodge conjecture then for a given pure Hodge structure H there is at most one connection ∇ such that H is a Hodge substructure of a cohomology group of a smooth projective complex variety with ∇ induced by the Gauß...

One of the targets of the recently launched Fermi Gamma-ray Space Telescope is a diffuse gamma-ray background from dark-matter annihilation or decay in the Galactic halo. N-body simulations and theoretical arguments suggest that the dark matter in the Galactic halo may be clumped into substructure, rather than smoothly distributed. Here we propose the gamma-ray-flux probability distribution fun...

We simulate the dynamics of fractal star clusters, in order to investigate the evolution of substructure in recently formed clusters. The velocity dispersion is found to be the key parameter determining the survival of substructure. In clusters with a low initial velocity dispersion, the ensuing collapse of the cluster tends to erase substructure, although some substructure may persist beyond t...

The symbolic value partition problem is more general than the reduct problem and more complicated than the discretization problem. In this paper, we point out that the symbolic value partition problem can be converted into a series of reduct problems and propose an algorithm called reduction based symbolic value partition (RBSVP) whose all possible outputs form the set of all partition reducts....
