... The compression of iflo/ lband receivers (lband wide , lband narrow) was measured on 29apr03. ... Center a band at 1415 Mhz and pass it through a 5 Mhz IF filter (centered at 260 MHz). ... Center another band at 1350,1330 Mhz. ... The 1350 data was normalized to full scale while the 1415 Mhz data was normalized to medianTsys -1 (so the radar 1350 scale and the 1415 Mhz scale are not the same). ... You can see the double bumps in the faa radar (this is the 1350 then 1330 pulses spaced by 6 usecs). ...

Let K be a global field. ... The real number $\gamma_K = c_0/c_{-1}$ is called the Euler-Kronecker constant of the field $K$. In the article of Yasutaka Ihara "On the Euler-Kronecker constants of global fields and primes with small norms" the lower bound $\gamma_K\ge-\log\sqrt{|d|}$ is obtained, where $d$ is the discriminant of the field $K$. In my talk I will prove the lower bound $\gamma_K\ge -\left(1-\frac{\sqrt{5}}{5}\right) \log\sqrt{|d|}$. ...

... Briefly, the count rate at the detector from a source at a redshift z is . ... Another possible way that could lead to arising diverse peculiarities in the - distribution induced by the sources evolution is connected with a possible non-monotonic character of the star formation rate in galaxies. ... The most prominent feature of the obtained theoretical - is a notable sharp increase at low count rates due to evolutionary effects. ...

... Using the uvby -photometry and proper motion data for about 5500 F stars within 80 pc from the Sun, we have studied velocity ellipsoid parameters and obtained the following results. 1) The sizw of all wllipsoid semiaxes increase systematically for groups of stars with the decrease of both temperature (at constant metallicity) and metallicity (at constant temperature). ... As a result, each of the three parameters - temperature, metallicity and velocity dispersion - is an age indicator. ...
