Our work tackles collective motion and decision-making in a primitive multicellular animal, Trichoplax adhaerens, enabling pioneering research into how intercellular coordination affects animal behavior and how migration accuracy scales with group size. Collective motion of cells is critical to some of the most vital tasks including wound healing, development, and immune response [Friedl and Gi...

Collective phenomena in biology can be a source of inspiration to propose multiagents methods in problem solving. They allow the design of individual behavior that are simple and that produce collectively complex phenomena. This article presents the process we followed to transpose a simulation model to a problem solving one. The initial biological context is the web building in social spider s...

— We review some of the key facts in the phenomenology of Pdhydrides usually referred to as «cold fusion». We conclude that all theoretical attempts that concentrate only on few-body interactions, both electromagnetic and nuclear, are probably insufficient to explain such phenomena. On the other hand we find good indications that theories describing collective, coherent interactions among eleme...

Recent experimental advances enable the fabrication of photonic lattices in which light propagates with non-trivial energy dispersions. When interfaced quantum emitters, such systems yield strong collective spontaneous emission phenomena, as perfect sub-radiance, decay into bath is completely suppressed, forming bound-states-in-the-continuum. Since are generally lossy, an alternative way probin...

The dispersal of cells from an initially constrained location is a crucial aspect of many physiological phenomena ranging from morphogenesis to tumour spreading. In such processes, the way cell-cell interactions impact the motion of single cells, and in turn the collective dynamics, remains unclear. Here, the spreading of micro-patterned colonies of non-cohesive cells is fully characterized fro...

The various kinds of flow phenomena such as directed flow, elliptic flow and radial flow have been observed in recent experiment at AGS and SPS [1]-[4]. Anisotropic flow phenomena are expected to show a strong dependence on the nuclear equation of state [5]. Here, for analyzing anisotropic flow phenomena with relativistic hydrodynamical model in detail, we need full calculation of (3+1)-dimensi...

The understanding of emergent collective phenomena in natural and social systems has driven the interest of scientists from different disciplines during decades. Among these phenomena, the synchronization of a set of interacting individuals or units has been intensively studied because of its ubiquity in the natural world. In this Letter, we show how for fixed coupling strengths local patterns ...

Collective phenomena in strongly nonequilibrium systems interacting with electromagnetic field are considered. Such systems are described by complicated non-linear differential or integro–differential equations. The aim of this review is to show that many nonlinear collective phenomena can be successfully treated by a recently developed method called the Scale Separation Approach whose name is ...
