The importance of catastrophe
or microtubule asters, just as with life in general, sometimes you get stuck in a corner. And, say Cendrine Faivre-Moskalenko and Marileen Dogterom (FOM Institute for Atomic and Molecular Physics, Amsterdam, Netherlands), it can take a catastrophe to get things moving again. Dogterom has been trying to reproduce aster behavior in the minimal environment of a microfabricated chamber. Her beads, ...
متن کاملCatastrophe Archetypes
We propose an Integrated Systemic Theory of Catastrophes (ISTC) using System Dynamics to model and to understand common systemic structures and behaviours of catastrophes. Current catastrophe research concentrates on a specific field and does not capture complex multi-field catastrophe scenarios that cannot be reduced to a single scientific field. For example, when looking at famines the elemen...
متن کاملEffects of the Chernobyl Catastrophe
On Saturday, April 26th, 1986 at 1:23 am, Block 4 of the nuclear power plant at Chernobyl exploded. The plant was located approximately 100 km north of the Ukrainian capital Kiev, near the border with Belarus. 180,000 kilograms of highly radioactive material is inside the reactor at the time an amount equal to 1,000 Hiroshima bombs. About 1019 Bq of radioactive material – consisting of at least...
متن کاملElectromechanical Catastrophe
A transducer is a system that couples two loads. For example, an electromechanical transducer couples a mechanical force and an electrical voltage. A two-load, nonlinear system can exhibit rich behavior of bifurcation, which can be displayed in a three-dimensional space, with the horizontal plane representing the two loads, and the vertical axis representing the state of the system. In this thr...
متن کاملDo Firms Manage Catastrophe and Non-Catastrophe Risks Differently?
Recent disasters and historical insurance payouts have triggered renewed interest in how firms manage their left-tail exposure. Using a unique dataset of fully described insurance policies purchased by large U.S. firms, we provide the first consistent estimates of premium elasticity of corporate demand for insurance for both catastrophe and noncatastrophe risks. We do so by combining this datas...
