1728Gondolo, PaoloDetectability of the Sgr dwarf leading tidal stream with Auger, EUSO, or OWLWe point out that if heavy metastable particles composing the dark matter of our galaxy are responsible for the ultrahigh energy cosmic rays (UHECR) then the leading tidal stream of the Sagittarius dwarf galaxy could be detected through UHECR. The signal would be an anisotropy in the UHECR flux sma...Sagittarius dwarf galaxy; Sgr stream; anisotropy2004-07
1729Gondolo, PaoloDetectability of weakly interacting massive particles in the Sagittarius dwarf tidal streamTidal streams of the Sagittarius dwarf spheroidal galaxy (Sgr) may be showering dark matter onto the solar system and contributing ~(0:3-23)% of the local density of our galactic halo.

1730Bruderlin, BeatDetecting ambiguities: an optimistic approach to robustness problems in computational geometryComputational geometry algorithms deal with geometric objects, usually represented by coordinates in an n-dimensional Euclidean space. Most efficient algorithms implement geometric operations as floating point arithmetic operations on the coordinates.

1733Mathews, V. JohnDetection and estimation with fixed lag for abruptly changing systemsThe problem of state estimation and system structure detection for discrete-time stochastic systems with parameters which may switch among a finite set of values is considered. The switchings are modeled by a semi-Markov, or Markov, chain with known transition statistics. A fixed time delay (lag) is...1983
