... Featured here is a dramatic video that captured some impressive pulsating auroras in mid-March over Svлnafellsjфkull Glacier in Iceland. ... The quick rapidity of the pulsations seen here is somewhat unusual -- more common are aurora with pulsations that last several seconds. Recent research shows that pulsations are more common in electron-generated aurora, rather than proton aurora , and that the Earth's local magnetic field may fluctuate in unison . ...

... The department was founded in late sixties by Prof. D.Ya.Martynov, who for many years was also the director of Sternberg Astronomical Institute. At present time, the head of the department is Prof. A.M.Cherepashchuk, a pupil of D.Ya.Martynov and his successor as the director of SAI. Since Prof. Martynov, the scientific activity of the department was primarily related to binary stars. ... The department consists of 15 members most of which have Ph.D. in Astrophysics. ...

Pulsars can be used to study the strong nuclear force. The density of matter at the center of neutron stars is one or two orders of magnitude larger than the density of atomic nuclei. ... Very "soft" EOSs predict lower pressures for a given density, i.e., highly compressible matter. ... If more precise measurements can confirm this high value, then many model EOSs for dense matter can be ruled out. ... Another way of studying the behavior of super-dense matter is to find fast pulsars. ...

The array was designed to detect compact radio sources such as these by virtue of the fact that they would scintillate (twinkle) when observed from the Earth through the interplanetary medium ? ... One of Antony Hewish?s research students, Jocelyn Bell, was set the task of operating the telescope and inspecting the daily charts for the kind deflections in the trace which occurred when a scintillating source passed over the array. ...

The aromatic features in M101 were studied spectroscopically and photometrically using observations from all three instruments on the Spitzer Space Telescope. The global SED of M101 shows strong aromatic feature (commonly called PAH feature) emission. ... This implies that the weakening of the aromatic emission in massive star-forming regions is due primarily to processing of the dust grains in these environments, not to differences in how they form. ...

The First Law (1): Energy is Conserved in a closed system: . ... We usually consider work and heat flow as the two kinds of energy . The Second Law (2): The Law of Entropy: . ... The amount of disorder increases . ... You can not go from a disordered system to an ordered system without inputting more energy (this is the most important attribute of the second law) . ... In no way can we recover work of that this disordered system without putting energy into the system. ... More on Thermodynamics . ...

This currently affects the behavior of comedi_to_phys() when converting endpoint sample values, that is, sample values equal to 0 or maxdata. If the out-of-range behavior is set to COMEDI_OOR_NAN, endpoint values are converted to NAN. If the out-of-range behavior is set to COMEDI_OOR_NUMBER, the endpoint values are converted similarly to other values. ...

. This diagram illustrates the behavior of margins, borders, and padding at the split points of an inline box. The illustration shows the rendering of the HTML example preceding the image in the main document, the paragraph "Several emphasized words appear here." The inline box containing the words "emphasized text" is split between the words. At the split point, padding, borders (dashed to emphasize them), and margins are not rendered. Return to image.

... Fractals and multifractals are used to model hierarchical, inhomogeneous structures in several areas of astrophysics, notably the distribution of matter at various scales in the universe. ... It is pointed out that some of the difficulties regarding the convergence rates of algorithms used to determine scaling exponents for a fractal or multifractal, are intrinsically related to its texture, in particular, to its lacunarity . ... Structures with fractal characteristics are important for astrophysics...
