A weighted pair graph representation for reconstructibility of Boolean control networks
A new concept of weighted pair graphs (WPGs) is proposed to represent a new
reconstructibility definition for Boolean control networks (BCNs), which is a
generalization of the reconstructibility definition given in [Fornasini &
Valcher, TAC2013, Def. 4]. Based on the WPG representation, an effective
algorithm for determining the new reconstructibility notion for BCNs is
designed with the help of the theories of finite automata and formal languages.
We prove that a BCN is not reconstructible iff its WPG has a complete subgraph.
Besides, we prove that a BCN is reconstructible in the sense of [Fornasini &
Valcher, TAC2013, Def. 4] iff its WPG has no cycles, which is simpler to be
checked than the condition in [Fornasini & Valcher, TAC2013, Thm. 4].Comment: 20 pages, 10 figures, accepted by SIAM Journal on Control and

OverPlotter: A Utility for Herschel Data Processing
The OverPlotter utility is a GUI tool written in Java to support interactive data processing (DP) and analysis for the Herschel Space Observatory within the framework of the Herschel Common Science System (HCSS)(Wieprecht et al 2004). The tool expands upon the capabilities of the TableViewer (Zhang &
Schulz 2005), providing now also the means to create additional overlays of sev-
eral X/Y scatter plots within the same display area. These layers can be scaled
and panned, either individually, or together as one graph. Visual comparison
of data with different origins and units becomes much easier. The number of
available layers is not limited, except by computer memory and performance.
Presentation images can be easily created by adding annotations, labeling layers
and setting colors. The tool will be very helpful especially in the early phases
of Herschel data analysis, when a quick access to contents of data products is
important
