RFC 6259 DTN Previous - Hop Insertion Block May 2011
This document defines an extension block for use with the DelayTolerant Networking (DTN) Bundle Protocol. This Previous-Hop Insertion Block (PHIB) extension block is designed to be inserted by a forwarding node to provide the endpoint identifier (EID) of an endpoint of which the forwarding node is a member so that this EID may be conveyed to the next-hop receiving node. Knowledge of an EID of a...
متن کاملThe star - burst galaxies NGC 278 , NGC 660 , NGC 3628 , NGC 4631 , and NGC 4666
Aims. We study the physical properties and mass of molecular gas in the central regions of galaxies with active nuclei. GHz [CI] maps in three of these are used to model the molecular gas. Results. All five objects contain bright CO emission in the central regions. Clear central concentrations were found in NGC 660, NGC 3628, and NGC 4666, but not in the weakest CO emitters NGC 278 and NGC 4631...
متن کاملThe Stellar Content of the Southern Tail of Ngc 4038/4039 and a Revised Distance
We have used the Hubble Space Telescope and Wide Field Planetary Camera 2 to image the putative tidal dwarf galaxy located at the tip of the Southern tidal tail of NGC 4038/4039, the Antennae. We resolve individual stars and identify two stellar populations. Hundreds of massive stars are present, concentrated into tight OB associations on scales of 200 pc, with ages ranging from 2 to 100 Myr. A...

متن کاملPerformance of the M11 and M11-L density functionals for calculations of electronic excitation energies by adiabatic time-dependent density functional theory.
Adiabatic time-dependent density functional theory is a powerful method for calculating electronic excitation energies of complex systems, but the quality of the results depends on the choice of approximate density functional. In this article we test two promising new density functionals, M11 and M11-L, against databases of 214 diverse electronic excitation energies, and we compare the results ...
