We present deep color-magnitude diagrams for two Subaru Suprime-Cam fields in the Virgo Stellar Stream(VSS)/Virgo Overdensity(VOD) and compare them to a field centred on the highest concentration of Sagittarius (Sgr) Tidal Stream stars in the leading arm, Branch A of the bifurcation. A prominent population of main sequence stars is detected in all three fields and can be traced as faint as g ≈ ...

We present an estimation of the closeness level between the distribution of RC4 keystream bytes (at some predefined locations in the stream) to a uniform distribution (over the same domain). Our estimation is based on the L1 distance between a pair of distributions over the same domain. Although learning the distance (empirically) between a distribution of a pair of consecutive bytes in the str...

This study investigates the inviscid, linear spatio-temporal stability of heated, compressible and incompressible coaxial jet flows. The influence of the temperature ratio and the velocity ratio between the core jet and the bypass stream on the transition from convectively to absolutely unstable flows is studied numerically. The investigation shows that for coaxial jets absolute instability can...

We use velocity and metallicity information from SDSS and SEGUE stellar spectroscopy to fit an orbit to the narrow 63◦ stellar stream of Grillmair and Dionatos. The stars in the stream have a retrograde orbit with eccentricity e = 0.33 (perigalacticon of 14.4 kpc and apogalacticon of 28.7 kpc) and inclination approximately i ∼ 35◦. In the region of the orbit which is detected, it has a distance...

Life-history characteristics are an important determinant of a species' dispersal abilities. We predict that variation in life history can influence population-level genetic patterns. To test this prediction, we estimate population-level genetic structure for two sympatric species of stream-breeding salamander. The Cope's giant salamander (Dicamptodon copei) rarely metamorphoses into a terrestr...

Hellinger distance has been successfully used as a tree splitting criterion in Hellinger Distance Decision Trees [10] (HDDT) for unbalanced static datasets. In unbalanced data streams, state-of-the-art techniques use instance propagation and standard decision trees to cope with the unbalanced problem. However it is not always possible to revisit/store old instances of a stream. We solve this pr...

The distribution and morphology of gold panicles from stream sediments, glacial tills and soils have been used to assess their distance from source (Antweiler and Campbell, 1977; Averill, 1988; Petts e/ ul.. 1991; Nikkarinen, 1991; Averill and Huneault, 1991; Grant et ul.. 1991). Here we present preliminary clata on the distribution and morphology of gold in Harris Crcek. southern British Colum...

The hydraulic relationship between the stream and aquifer can be altered from hydraulic connection to disconnection when the pumping rate exceeds the maximum seepage flux of the streambed. This study proposes to quantitatively analyze the physical processes of stream-aquifer systems from connection to disconnection. A free water table equation is adopted to clarify under what conditions a strea...

in this study, the systematic position of acanthalburnus microlepis from kura and aras basins is clarified and some notes on the taxonomy of the acanthobrama species distributed in turkey are given. based on the morphological and osteological analyses, a high similarity between a. microlepis and acanthobrama members is found. some taxonomic information yielded from the examination of recent col...
