Asexuals are an important test case for theories of why species exist. If asexual clades displayed the same pattern of discrete variation as sexual clades, this would challenge the traditional view that sex is necessary for diversification into species. However, critical evidence has been lacking: all putative examples have involved organisms with recent or ongoing histories of recombination an...

Components which are developed independently but have similar behaviour, generally cannot be substituted for use by a client due to structural differences and minor but subtle behavioural differences. An automated solution for adaptation of these mismatches would be desirable. Although automatic adaptation has been addressed by recent works, it fails to go beyond simple structural differences. ...

OBJECTIVES It has been widely accepted in the literature that various forms of physical exercise, even in a single session, enhance positive mood. It has also been shown that physical exercise may sometimes enhance creative thinking, but the evidence is inconclusive. Positive moods can favour creative thinking, but the opposite has also been reported and these relations are unclear. There is a ...

This thesis presents the LiquiMedia operating system architecture. LiquiMedia is specialized to schedule multimedia applications. Because they generate output for a human observer, multimedia applications such as video games, video conferencing and video players have both unique scheduling requirements and unique allowances: a multimedia stream must synchronize sub-streams generated for differe...

An innovative biological energy has been observed related to the eye sight and fusing with another energy over tap water through a small metallic chain. The fused energy has been repeatedly described under standard conditions and it is characteristics vary according to the condition of the eye sight and the water content. This energy may be called: "EFI" (energy functioning, by fusion, independ...

The aim of this paper is to provide a new method for learning the relationships between data that have been obtained independently. Unlike existing methods like matching, the proposed technique does not require any contextual information, provided that the dependency between the variables of interest is monotone. It can therefore be easily combined with matching in order to exploit the advantag...

Two shortest paths P (u, v) and P ′(v, u) are called converging paths if path P (u, v) is exactly the reversal of path P ′(v, u). Independently finding two converging paths from node u and node v, so that a message from u to v is bound to meet a message from v to u, is not trivial even if both nodes have the correct and complete network link state information. This paper presents three differen...

The expression problem is fundamental for the development of extensible software. Many (partial) solutions to this important problem have been proposed in the past. None of these approaches solves the problem of using different, independent extensions jointly. This paper proposes solutions to the expression problem that make it possible to combine independent extensions in a flexible, modular, ...

We propose a model of distributed timed systems where each component is a timed automaton with a set of local clocks that evolve at a rate independent of the clocks of the other components. A clock can be read by any component in the system, but it can only be reset by the automaton it belongs to. There are two natural semantics for such systems. The universal semantics captures behaviors that ...
