Recent decades have seen rapid development of new analytical methods to investigate patterns of interspecific variation. Yet these cutting-edge statistical analyses often rely on data of questionable origin, varying accuracy, and weak comparability, which seem to have reduced the reproducibility of studies. It is time to improve the transparency of comparative data while also making these impro...

Following some previous studies on list automata and restarting automata, we introduce a generalized and refined model – the h-lexicalized restarting list automaton (LxRLAW). We argue that this model is useful for expressing transparent variants of lexicalized syntactic analysis, and analysis by reduction in computational linguistics. We present several subclasses of LxRLAW and provide some var...

We describe the application of a generic stability framework for a teleoperation system under time-varying delay conditions, as addressed in a previous work, to a scaled-four-channel (γ-4C) control scheme. Described is how varying delays are dealt with by means of dynamic encapsulation, giving rise to mu-test conditions for robust stability and offering an appealing frequency technique to deal ...

We report a large-scale coronal wave (so-called “EIT wave”) observed with high cadence by EUVI onboard STEREO in association with the GOES B9.5 flare and double CME event on 19 May 2007. The EUVI instruments provide us with the unprecedented opportunity to study the dynamics of flare/CME associated coronal waves. The coronal wave under study reveals deceleration, indicative of a freely propagat...

Public and private organizations in various areas are setting up digital Information Infrastructures (IIs) for interconnecting government, businesses and citizens. IIs can create value by sharing and integrating data of multiple actors. This can be the basis for value added services and especially collaborations of public and private partners can make IIs thrive. Easier access to integrated ser...

We review the current status of the ’Parker hypothesis’ which suggests that the solar corona is heated by a multitude of small flare-like events called nanoflares. Space-born coronal imagers such as SXT, EIT or TRACE have allowed to test Parker’s hypothesis observationally. Combining the results from different authors it seems that we are close to falsifying the hypothesis, i.e. there are not e...
