Abstract The big challenges in education and R&D activities in the century just started are related on the complexity and transdisciplinarity understanding and promotion.The approaches are necessary in order to understand the unity of the world we live in through the unity of knowledge.The complexity is the result of the integration process.The paper presents fundamentals of the integration-intrication process in the nature and technology.The concept of integronics and the basic principles of the integration process are outlined too. Also the main features of mechatronics as environment for transdisciplinarity learning and the concept of integral education promotion are presented.The advanced mechatronics and the embedded systems are fundamentals of the cyberphysical systems of the future

Networked Embedded Systems have come to occupy an important role in emerging applications. Nodes in such a system are interconnected by a mesh topology. Despite the availability of multiple shortest paths between pairs of nodes, simulation results revealed that these paths cannot be effectively exploited by spreading the messages over the paths in a uniform method. We define the union of all the shortest paths between a pair of nodes as a contour. We present results that characterize the structure of contours when each node communicates directly with eight immediate neighbors. Heuristic rules that effectively disseminate messages over the available paths are presented. Simulation results demonstrate that the new method for dissemination ensures that nodes in a contour, which are at the same distance from the source, handle roughly the same number of messages. In the future, such techniques can be extended to general topologies.

A symposium on the future of the International Latitude Service (I. L. S.) is to be held in Helsinki in July 1960. My report for the symposium consists of two parts. Part I, denoded (Mk I) was published [1] earlier in 1960 under the title “Latitude and Longitude, and the Secular Motion of the Pole”. Part II is the present paper, denoded (Mk II).

Second-epoch photographs have now been obtained for nearly 850 of the 1246 fields of the proper motion program with centers at declination -20° and northwards. For the sky at 0° and northward only 130 fields remain to be taken in the next year or two. The 270 southern fields with centers at -5° to -20° remain for the future.

Metaphase chromosomes from human and mouse cells in vitro are isolated by micrurgy, fixed, and placed on grids for electron microscopy. Interpretations of electron micrographs by current methods indicate the following structural features.Chromosomal spindle fibrils about 200Å thick form fascicles about 600Å thick, wrapped by dense spiraling fibrils (DSF) less than 100Å thick as they near the kinomere. Such a fascicle joins the future daughter kinomere of each metaphase chromatid with those of adjacent non-homologous chromatids to either side. Thus, four fascicles (SF, 1-4) attach to each metaphase kinomere (K). It is thought that fascicles extend from the kinomere poleward, fray out to let chromosomal fibrils act as traction fibrils against polar fibrils, then regroup to join the adjacent kinomere.
