Branching network is one of the most universal phenomena in living or non-living systems, such as river systems and the bronchial trees of mammals. To topologically characterize the branching networks, the Branch Length Similarity (BLS) entropy was suggested and the statistical methods based on the entropy have been applied to the shape identification and pattern recognition. However, the mathe...

Interactions between neuronal assemblies form a basis for the mechanism of functional integration that underlies most of our actions. Studying these interactions is important for understanding the principles of brain operation. However, such neuronal communications are hallmark of a living brain and therefore it is of paramount importance to develop tools for imaging of these interactions on th...

The link between robotic systems and living systems is increasingly considered to be important. However finding out more precisely which properties these two kinds of system must share is a difficult question to answer. It is suggested that behavioral plasticity constitutes a crucial property that robots must share with living beings. A classification is then proposed for the different aspects ...

Installing and using AAL Smart Home-systems in the homes of older people not only offers a tremendous potential for increasing safety and quality of life but may also evoke reluctance and anxiety. Will such a system become a “Big Brother” watching the steps and the behaviour of the inhabitants and betray them to their outside world? In several field-trials of an AAL Smart Home-system with inhab...

A. E. Carlsson Department of Physics, Washington University, St. Louis, Mo. 63130 (Dated: February 2, 2008) Abstract Theory and experiment have established that F-actin filaments are strongly attached to the intracellular parasites (such as Listeria) they propel with “comet tails”. We consider the implications of these observations for propulsion. By calculating the motion produced in various m...
