Neuronal Avalanches

It has recently been suggested that, in order to provide the richness of behavior which is seen empirically, the brain must operate in a critical regime between a phase of order and disorder [1]. In particular, such critical behavior is exhibited in what is termed neuronal avalanches. These cascades of synaptic activity have been seen both in vitro and in vivo [6]. Several models have been put ...

Honeybee: The flying pharmacist

Honeybee, a small -although powerful- creature moves from one place to another to make an elixir, which cures different diseases. To make one kilogram of honey the small creature has to carry 150000 pieces of pollen and suck the sap of ten million flowers. Both honey and the honeybee poison have been used in treating diseases for thousands of years. The product made by such tiny creatures has b...

Mechanics of snow avalanches

The main problems of mechanics of snow avalanches are those of: (1) predicting avalanches, (2) avalanche motion, (3) the action of an avalanche upon obstacles, (4) the air wave, (5) the slow moving snow cover and its interaction with protective constructions and (6) the problem of artificial release of avalanches. This paper surveys the modern state of scientific knowledge about the nature of p...
