Mia Hubert, Peter Rousseeuw and Pieter Segaert (subsequently HRS) are to be praised for having developed a visual and well applicable methodology of treating outliers in functional data. Their principal achievements include a systematics of functional outliers, novel visualizations and a measure of outlyingness (bagdistance), which nicely combines Euclidean distance with location depth. Most im...

Context. The multi-wavelength study of old (>100 Myr) radio pulsars holds the key to understanding the long-term evolution of neutron stars, including the advanced stages of neutron star cooling and the evolution of the magnetosphere. Optical/UV observations are particularly useful for such studies because they allow one to explore both thermal and non-thermal emission processes. In particular,...

Content based image retrieval technology has been proposed to benefit not only management of increasingly large image collection, but also to aid clinical care, biomedical research and education. In this paper, lifting scheme is proposed for content based retrieval method for diagnosis aid in medical field. Content-based image retrieval (CBIR) techniques could be valuable to radiologists in ass...

Brightness temperature (TB) observations at an infrared channel (10.3 ?m) of the Advanced Baseline Imager (ABI) on board U. S. 16th Geostationary Operational Environmental Satellite (GOES-16) are used for determining tropical cyclone (TC) center positions and rainband sizes. Firstly, azimuthal spectral analysis method is employed to obtain azimuthally symmetric a TC. Then, inner outer rainbands...

Most known results on avoiding the occur-check are based notion of "not subject to occur-check" (NSTO). It means that unification is performed only such pairs atoms for which never succeeds in any run a nondeterministic algorithm. Here we show this requirement too strong. We how weaken it, and present some related sufficient conditions under may be safely omitted. examples proposed approach pro...
