We present an exhaustive quantitative comparison of all the known extinction curves in the Small and Large Magellanic Clouds (SMC and LMC) with our understanding of the general behavior of Milky Way extinction curves. ... The near-infrared extinction curves are calculated mainly from 2MASS photometry supplemented with DENIS and new JHK photometry. ... This result strengthens the picture dust extinction curves exhibit of a continuum of properties between those found in the Milky Way and the SMC bar. ...

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. ...

... Effect of vortex fluctuations on 205 Tl spin-lattice relaxation in the mixed state of Tl 2 Ba 2 CuO 6 . ... The spin-lattice relaxation rate W on 205 Tl has been measured in the mixed state of a Tl 2 Ba 2 CuO 6 aligned powder sample with T c =100 K. At T < 25 K, W T and decreases with increasing magnetic field. This behavior is explained as caused by fluctuations of pancake vortices; the latter induce a time dependent random magnetic field which causes the relaxation of nuclear spins. ...

... An OBJECT column gives the name of the object observed (usually a star name). ... In critical cases, it is common practice to measure sky on two or more positions around a target object, and these positions must be identified. ... A general treatment of this problem requires a column called OBJECT, bearing the usual name of the object (as in the star tables); a column labelled STARSKY, to distinguish between star+sky, star alone, or sky alone; and additional columns to identify the sky position. ...

This lesson is intended as a revision of basic direct-current (DC) circuits . It was discovered in the 19th century that certain materials (so-called ideal resistors) have a current through them I that is proportional to the potential difference (voltage) across them V. This is not a fundamental law of physics (like momentum conservation) but is an observed behavior which some materials roughly follow (like the friction law we covered earlier in the course). ... This equation is called Ohm's law. ...
