Hindbrain patterning requires many factors involved in early segmentation and later segment identity of the specific domains of the hindbrain. Hox proteins and their cofactors are of great importance durng segmentation of the hindbrain, because segmentation and/or segment identity are lost when any of them are lost. Previously, we have reported that Meis proteins synergize with Pbx, another Hox...

Aiming at complex labyrinth-channel emitters’ structure and the practical problem of clogging, this paper investigates the practical flow of water, mixed with sand escaped from filtering, in the labyrinth channel. CFD analysis has been performed on liquid-solid two-phase flow in labyrinthchannel emitters. Based on micro-PIV (particle image velocimetry) flow visualization technology, the flow in...

The development of future software for proposed new computer architectures is expected to make significant demands on compiler technologies. Significant rewriting of applications will be likely to support the use of new hardware features and preserve the current software investment. Existing compilers provide little support for the broad range of research efforts addressing exascale challenges,...

Directed graphs are ubiquitous in most aspects of software analysis. Presented abstractly, as a list of edges, a graph does not manifest much of the important structural information that becomes obvious if the graph displayed pictorially. This paper presents a technique for drawing directed graphs quickly and attractively. It also describes how a tool implementing this technique has been used, ...

In our study of the extremities of a graph, we define a moplex as a maximal clique module the neighborhood of which is a minimal separator of the graph. This notion enables us to strengthen Dirac’s theorem (Dirac, 1961): ‘‘Every non-clique triangulated graph has at least two non-adjacent simplicial vertices’’, restricting the definition of a simplicial vertex; this also enables us to strengthen...
