A combinatorial approach to binary positional number systems [PDF]

open access: yesActa Mathematica Hungarica, 2013
A binary radix system for \({\mathbb R}^+\) is a pair \((B,\Gamma)\), where \(B>1\) is a real number called the base and \(\Gamma\) is a subset of all sequences with terms \(0,1\) denoted \(\{0,1\}^{\infty}\) with a ``decimal dot'' called the address space such that \(\Gamma\) is shift invariant and \(\pi:\Gamma\mapsto [0,1]\) given by \[ \pi(\omega_0 ...

Desirable properties for XML update mechanisms [PDF]

open access: yes, 2010
The adoption of XML as the default data interchange format and the standardisation of the XPath and XQuery languages has resulted in significant research in the development and implementation of XML databases capable of processing queries efficiently ...

Hard X-ray Emission Associated with White Dwarfs [PDF]

open access: yes, 2003
We have used the WGACAT to search for hard X-ray sources associated with white dwarfs (WDs) from the catalog of McCook & Sion (1999). We find 17 X-ray sources coincident with WDs showing significant hard X-ray emission at energies >0.5 keV.

Quantitative games with interval objectives [PDF]

open access: yes, 2014
Traditionally quantitative games such as mean-payoff games and discount sum games have two players -- one trying to maximize the payoff, the other trying to minimize it.

Cataclysmic Variables and Other Compact Binaries in the Globular Cluster NGC 362: Candidates from Chandra and HST

open access: yes, 2010
Highly sensitive and precise X-ray imaging from Chandra, combined with the superb spatial resolution of HST optical images, dramatically enhances our empirical understanding of compact binaries such as cataclysmic variables and low mass X-ray binaries ...

Universal Indexes for Highly Repetitive Document Collections [PDF]

open access: yes, 2016
Indexing highly repetitive collections has become a relevant problem with the emergence of large repositories of versioned documents, among other applications.

Accurate Coordinates and 2MASS Cross-IDs for (Almost) All Gliese Catalog Stars [PDF]

open access: yes, 2010
We provide precise J2000, epoch 2000 coordinates and cross-identifications to sources in the 2MASS point source catalog for nearly all stars in the Gliese, Gliese and Jahreiss, and Woolley catalogs of nearby stars.

BOOL-AN: A method for comparative sequence analysis and phylogenetic reconstruction [PDF]

open access: yes, 2009
A novel discrete mathematical approach is proposed as an additional tool for molecular systematics which does not require prior statistical assumptions concerning the evolutionary process.

The Rate of Short-Duration Gamma-Ray Bursts in the Local Universe

open access: yes, 2018
Following the faint gamma-ray burst, GRB 170817A, coincident with a gravitational wave-detected binary neutron star merger at $d\sim40$ Mpc, we consider the constraints on a local population of faint short duration GRBs (defined here broadly as $T_{90}

M 33 X-7: ChASeM33 reveals the first eclipsing black hole X-ray binary [PDF]

open access: yes, 2006
The first observations conducted as part of the Chandra ACIS survey of M 33 (ChASeM33) sampled the eclipsing X-ray binary M 33 X-7 over a large part of the 3.45 d orbital period and have resolved eclipse ingress and egress for the first time.
