... Program: . ... There are twenty one math courses and two theoretical computer science courses. Besides math and computer science courses, a Russian language course, courses in Russian history, history of science and Russian literature (in English) are offered. ... However, we are aware that most students in the Math in Moscow program do not have as much math problem solving experience as Russian students of the same age. ... One "Math in Moscow" course transfers as three or four semester hours. ...

. Fig. The SOHO/EIT 171 image (a) illustrating a pronounced transequatorial inverted V-shaped chain 1-2-3-4 which appears to outline the large soft X-ray CH observed with the Yohkoh/SXT (b) on March 1-2, 1999. The BBSO H-alpha (c) and MLSO/HAO He I 10830 (d) heliograms are shown to demonstrate relation of this and some other EUV chains to other large-scale structures such as H-alpha filaments and He I 10830 features.
