The Hellas2xmm Survey: I. the X-ray Data and the Log(n)-log(s)
We present the first results from an XMM-Newton serendipitous medium-deep survey, which covers nearly three square degrees. We detect a total of 1022, 495 and 100 sources, down to minimum fluxes of about 5.9× 10−16, 2.8× 10−15 and 6.2× 10−15 erg cm−2 s−1, in the 0.5-2, 2-10 and 4.5-10 keV band, respectively. In the soft band this is one of the largest samples available to date and surely the la...
متن کاملStUSPACE(log n) <= DSPACE(log²n / log log n)
We present a deterministic algorithm running in space O ? log 2 n= log logn solving the connectivity problem on strongly unambiguous graphs. In addition, we present an O(logn) time-bounded algorithm for this problem running on a parallel pointer machine.

متن کاملThe Milky Way in X-rays for an outside observer Log(N)-Log(S) and Luminosity Function of X-ray binaries from RXTE/ASM data
We study the Log(N)–Log(S) and X-ray luminosity function in the 2–10 keV energy band, and the spatial (3-D) distribution of bright, LX ≥ 10−10 erg/s, X-ray binaries in the Milky Way. In agreement with theoretical expectations and earlier results we found significant differences between the spatial distributions of low (LMXB) and high (HMXB) mass X-ray binaries. The volume density of LMXB source...
متن کاملAsymptotic Slope of Log Pressure
The goal of this study was to develop, on a rational basis, an index of the intrinsic diastolic elastic properties of the left ventricle. A relatively simple analytic model employing a thin-walled spherical geometry coupled with an approximate formulation of a two-dimensional constitutive relation, was used to examine the primary determinants of the pressure-volume relationship of the intact he...
