... Email: chaos@mail.cplire.ru . ... We investigate phenomena on the edge of spatially homogeneous chaotic mode and spatiotemporal chaos in a lattice of chaotic 1-D maps with local connections. We show that spatially homogeneous chaotic mode cannot exist in a lattice with local connections if the Lyapunov exponent of the isolated chaotic map is greater than some critical positive value. We propose a few schemes that make spatial synchronization possible in large lattices. ...

The velocity dispersion anisotropy and mass-to-light ratio of elliptical galaxies . van der Marel R.P. MNRAS, 253, 710-726, 1991 . ... The observed velocities in the outer parts of the galaxies in the sample systematically exceed the velocities predicted by the (constant mass-to-light ratio) models. From this it is argued that no axisymmetric constant mass-to-light ratio models can fit the kinematical data in the outer parts of elliptical galaxies. ...

A PL EMBEDDING OF THE 2­SPHERE IN R 4 WITH NON­STANDARD REGULAR NEIGHBORHOOD Eugene Rafikov and Duџ san Repovџ s Abstract. We construct a (non­locally flat) PL embedding S 2 ae R 4 such that the regular neighborhood of S 2 in R 4 is not homeomorphic to S 2 \Theta D 2 . ... Our example is based on construction of a knot, concordant to the trivial one but (with any frame) not Kirby­equivalent to the trivial knot with the frame 0. ...

. Authors: A.A. Suchkov , V.A. Marakov . Journal: Pis'ma Astron. Zh., 1976, v.2, p.38-385. Metallisity function of globular clusters in the Galaxy is constructed. It is found to have three "humps". This leads to a conclusion that there were three metal enrichment outbursts during the period of globular cluster formation. The constraints on the nature of metal sourses and on the early evolution of Galaxy are considered.

We investigate models for main-sequence and horizontal-branch (HB) stars constructed using the Carson opacities and make comparisons with models based on the Cox-Stewart opacities. ... The drop in the hydrogen-shell luminosity due to the helium-core expansion during HB evolution is greater than that obtained with the Cox-Stewart opacities. ... Studies of main-sequence (MS) stars lead to agreement with Stothers' (1974a,b, 1976) results for homogeneous models constructed with Carson opacities. ...

ABSTRACT . Single electron detection is desirable in systems incorporating EBCCDs. The sources of noise in single electron counting are discussed and an expression is given for the total noise. INTRODUCTION . Electron bombarded charge coupled devices (EBCCDs) have been recognized as having performance advantages over competing technologies in terms of their high sensitivity, low noise and high spatial resolution. ...
