Let A Rn be a closed subset, let C Rn be a compact subset. ... A subset K R is compact if and only if it is bounded and closed. ... Prove that (a) the image of a connected space under a continuous map is connected; (b) the same, for path connectedness; (c) an open subset in Rn is connected if and only if it is path connected. ...

... The common identifier of this star system is G89-14. Initially, there were known just two close spectroscopic components in this system, A and B, orbiting around each other with a period of about 190 days (Carney et al., ... Subsequently, at a separation of 34 arc seconds from this spectroscopic pair, Allen et al. (2000) found its companion D with common proper motion (Fig.1, right, and Fig.2). ... The uniqueness of this star is that it is the most metal-poor quadruple system known to date. ...

Starting with the Apache 1.2 betas, people are reporting many more connections in the FIN_WAIT_2 state (as reported by netstat ) than they saw using older versions. When the server closes a TCP connection, it sends a packet with the FIN bit sent to the client, which then responds with a packet with the ACK bit set. ... Some users have observed no FIN_WAIT_2 problems with Apache 1.1.x, but with 1.2b enough connections build up in the FIN_WAIT_2 state to crash their server. ...
