... 8, ``Celestial Mechanics'', 2002 Investigation of stability of NEAs orbital resonance motions by numerical methods L. E. Bykova Tomsk State University, Tomsk, Russia The problem of orbital stability of resonance Near­Earth asteroids (NEAs) is considered. Most of NEAs have multiple close approaches to the inner ma­ jor planets. ... The technique of the investigation of NEAs orbital stability has been devel­ oped by author on the basis of the construction of possible motion domains (R) of asteroids. ...

... The most powerful and widely used methods to calculate the scattering matrix of a fractal cluster are based on the coupled dipoles methods (e.g. the Discrete Dipole Approximation, DDA) and the theory of light scattering by a cluster of spherical particles [2-4]. ... At present the procedure of calculation of the scattering matrix is well developed for both an oriented cluster of spherical particles and for chaotically oriented clusters of such particles [4]. ...

Down) observed and imaged the unusual near-Earth asteroid 2000PH during its close approach to the Earth around 27 July 2004. The observations were carried out remotely using the new 2m aperture Faulkes telescope situated on the 10,000-foot summit of Haleakala, on the island of Maui in Hawaii. ...

REPORT ON PIERRE DELIGNE FELLOWSHIP, 2010 SERGEY OBLEZIN During 2010 I have been working on developing a representation theory approach to mirror symmetry and quantum cohomology of homogeneous spaces, associated to Lie groups of classical type. According to Givental the glN -Whittaker functions, being solutions to the quantum cohomology D-module QH (FlN ) of the complete flag variety FlN = GLN (C)/B , describe the corresponding equivariant Gromov-Witten invariants of FlN . ...

... Because the DMR instrument is differential and every pixel is multiply sampled, sky maps are produced by solving a coupled system of linear equations (the normal equations) to minimize a chi-squared. ... This is reflected in the algebraic form of the normal equations matrix, so that, if one were to diagonalize the matrix, one would find a single eigenvector whose eigenvalue was identically zero, and the associated eigenvector, viewed as a sky map, would have a constant value. ...

... This calibration approach is recommended when dealing with high frequency data from the old ATCA correlator, especially at 3mm wavelengths. ... The approach described here exploits the dual frequency bands that were available with the old correlator. ...

Эта эмблема была разработана для экипажей корабля OV 101 Enterprise, на котором в 1977 году проводились испытательные полеты (Approach and Landing Test) в атмосфере при сбрасывании с самолета Boeing-747 на высоте в 25000 футов (7 620 м). Эмблема представляет собой круг, сочетающий в себе синий, белый и красный цвета - основные цвета американского флага. На красном треугольнике, обращенном острой вершиной вверх, символизируя стремление в космос, помещено изображение шаттла Enterprise. ...

... arXiv.org . ... Modeling Light Curves for Improved Classification . ... These include heterogeneity of the data, irregularly sampled data, missing data, censored data, known but variable measurement errors, and most importantly, the need to classify in astronomical objects in real time using these imperfect light curves. We describe a modeling-based approach using Gaussian process regression for generating critical measures representing features for the classification of such lightcurves. ...
