Merging Physics And Neuroscience: First Evidence Of Self-Organized Criticality In Brain Networks
...hat gradually reach a critical state -- leading to avalanches ofvarying sizes -- as grains of sand are slowly added. The work andits implications remain controversial in the physics community. In brain cells, random firing of neurons creates noise thatmoves the system toward criticality, Jung explained. Wit...... Desert'srichest fossil site were killed by sudden avalanches of water-soaked sandflowing down the sides of dunes.

...ountain, which should make them less vulnerable to avalanches and medical problems, the leading causes of death among mountaineers. Messner also argued against using supplemental oxygen, saying it results in downgrading Everest to a 20,000-foot mountain.

They alternated with explosive events, which emplaced ignimbrites, probably related to the formation of two calderas, and pyroclastic flows, surges, and tephra falls.
