Firing back
voluntarily herd shoals of fish towards fishing boats. The fishermen benefit from enhanced catches and the dolphins feed on the entrapped fish, as well as getting some rewards from the fishermen. Nonetheless, numbers of dolphins have declined in Myanmar as a result of electrocution through illegal electric fishing, entanglement in nets, mercury poisoning and habitat loss from gold mining. Myanm...
متن کاملOn the back-firing instability.
The onset of the back-firing instability is studied in a one-dimensional spatially extended and dissipative system, where propagating localized solutions become unstable. It corresponds to the emission in the tail of a solitary wave of a new wave propagating in the opposite direction. The transition is illustrated, in geometrical terms, using a model normal form equation. (c) 2004 American Inst...
متن کاملFiring back: how great leaders rebound after career disasters.
Among the tests of a leader, few are more challenging-and more painful-than recovering from a career catastrophe. Most fallen leaders, in fact, don't recover. Still, two decades of consulting experience, scholarly research, and their own personal experiences have convinced the authors that leaders can triumph over tragedy--if they do so deliberately. Great business leaders have much in common w...
متن کاملFiring Hot, Firing Cold: How Poikilotherms Compensate for Temperature Swings
If you are reading this, you have one less problem than the crabs that are the subject of a new study in this issue of PLoS Biology. Humans, like all mammals (as well as birds), are ‘‘warm-blooded,’’ or more correctly ‘‘homeothermic,’’ meaning we maintain our core body organs at a constant temperature. We expend considerable energy to do so, and may die when we cannot. In contrast, crabs, cod, ...
متن کاملFiring Patterns in the Parallel Chip-Firing Game
The parallel chip-firing game is an automaton on graphs in which vertices “fire” chips to their neighbors. This simple model, analogous to sandpiles forming and collapsing, contains much emergent complexity and has connections to different areas of mathematics including self-organized criticality and the study of the sandpile group. In this work, we study firing sequences, which describe each v...
