Earlier models of kinetic artificial creatures typically describe ontogenetic mechanisms and motion control mechanisms separately. The latter are often assumed free from morphological constraints, reducing the biological and physical plausibility of these creatures. To go over these limitations, here we propose “Wriggraph”, a kinetic graph model that describes both ontogeny and motility of grap...

The study of evolving physically situated and virtually embodied artificial creatures has been a hotbed of research in recent years. The availability and maturation of commercial-off-the-shelf physics engines coupled with the dramatic increase of personal computing power have encouraged widespread research into this intriguing field of artificial life. This paper provides a comprehensive survey...

In this paper, we discuss our challenge on how to give the creatures and ability to follow spatial restriction while keeping the complexity low enough to still allow for real-time simulation of the herd. Our methodologies extend the pioneering work by Reynolds' flocking algorithm. We extend how the herd can move in natural-looking paths. Also, we show like the creatures to travel smoothly in 3D...

Relativistic corrections to the strange axial form factor are evaluated within a light-cone formalism, taking into account effects due to the breaking of Lorentz covariance associated with the use of one-body currents. Similar corrections are known to also be needed for the magnetic form factor, and we discuss the importance of these for recent data on strange electromagnetic form factors from ...

There are several different experimental indications, such as the σπN term, strange spin polarization, strangeness contribution to the magnetic moment of the proton, ratio of strange and non strange quark flavor distributions which suggest that the nucleon contains a hidden strangeness component which is contradictory to the naive constituent quark model. Chiral constituent quark model with con...
