... These Frontier Fields will combine the power of HST with the natural gravitational telescopes of high-magnification clusters of galaxies. ... We are soliciting gravitational lensing maps for the last four Hubble Frontier Fields clusters (MACSJ0717.5+3745, MACSJ1149.5+2223, AbellS1063, and Abell 370) based upon the exceptionally deep HST FF imaging and other new ancillary data. ... For the full set of proposal instructions and requirements, see the FY16 Frontier Fields Lensing Map Call for Proposals....

... As a result of BTA observations of 23 chemically peculiar stars with strong magnetic fields, it was found that in 22 of them the longitudinal magnetic field, measured from the hydrogen line cores are considerably lower (by about 1/3) than the value measured from metal lines in the same spectra. ... New approaches need to be developed in order to interpret the data. ... The Zeeman spectrum of a star with a strong magnetic field, 53 Cam. ...

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 $\gamma_K\ge -\left(1-\frac{\sqrt{5}}{5}\right) \log\sqrt{|d|}$. ...

... Bit Fields . Bit Fields: Practical Example . ... NOTE: The combination of pointers and bit-level operators makes C useful for many low level applications and can almost replace assembly code. ... To illustrate many points of bitwise operators let us write a function, Bitcount , that counts bits set to 1 in an 8 bit number ( unsigned char ) passed as an argument to the function. int bitcount(unsigned char x) { int count; for (count=0; x != 0; x>>=1); if ( x & 01) count++; return count; } . ...

... It was believed that the inside of the Earth was magnetized in the same fashion, and scientists were greatly puzzled when they found that the direction of the compass needle at any place slowly shifted, decade by decade, suggesting a slow variation of the Earth's magnetic field. ... Edmond Halley (of comet fame) ingeniously proposed that the Earth contained a number of spherical shells, one inside the other, each magnetized differently, each slowly rotating in relation to the others. ...

... 2 Magnetic Field . ... A magnetized bar has its power concentrated at two ends, its poles ; they are known as its north (N) and south (S) poles, because if the bar is hung by its middle from a string, its N end tends to point northwards and its S end southwards. ... That flow became known as an electric current . ... An electric current produced a magnetic force! ... The fundamental nature of magnetism was not associated with magnetic poles or iron magnets, but with electric currents . ...
