Ozone column amounts obtained by the total ozone mapping spectrometer (TOMS) in the southern polar region are analyzed during late austral winter and spring (days 240-300) for 1980-1991 using area-mapping techniques and area-weighted vortex averages. The vortex here is defined using the -50 PVU (1 PVU = 1.0 x 10(-6) K kg-1 m2 s-1) contour on the 500 K isentropic surface. The principal results...
Hans Asperger studied mental abnormalities in children in Vienna, Austria, in the early twentieth century. Asperger was one of the early researchers who studied the syndrome that was later named after him, Asperger's Syndrome. Asperger described the syndrome in his 1944 publication Die Autistischen Psychopathen im Kindesalter (Autistic Psychopathy in Childhood). At that time, the syndrome was c...
I present a practical configuration space computation algorithm for pairs of curved planar parts based on the general algorithm developed by Bajaj and me. The general algorithm advances the theoretical understanding of configuration space computation, but is too slow and fragile for some applications. The new algorithm solves these problems by restricting the analysis to parts bounded by line s...
We present the result of searches for gravitational waves from 200 pulsars using data from the first observing run of the Advanced LIGO detectors. We find no significant evidence for a gravitationalwave signal from any of these pulsars, but we are able to set the most constraining upper limits yet on their gravitational-wave amplitudes and ellipticities. For eight of these pulsars, our upper li...
