Nuclear power has prevented 1.84 million air pollution deaths and could save millions more in the coming decades Using nuclear power in place of fossil-fuel energy sources, such as coal, has prevented some 1.84 million air pollution-related deaths globally and could save millions of more lives in coming decades, concludes a study. The researchers also find that nuclear energy prevents emissions of huge quantities of greenhouse gases. These estimates help make the case that policymakers should continue to rely on and expand nuclear power in place of fossil fuels to mitigate climate change.   Environmental Science and Technology Journal - Prevented mortality and greenhouse gas emissions from historical and projected nuclear power by Pushker A. Kharecha and James E Hansen. Hansen is a famous NASA scientist who is well known for his position to stop climate change.

A look at lowering the deaths per terawatt hour by reducing pollution and making energy safer. A review of peer reviewed studies of air pollution deaths.

However, finding sparse codes remains a very difficult computational problem. In this paper, we present efficient sparse coding algorithms that are based on iteratively solving two convex optimization problems: an L1-regularized least squares problem and an L2-constrained least squares problem. We propose novel algorithms to solve both of these optimization problems. Our algorithms result in a significant speedup for sparse coding, allowing us to learn larger sparse codes than possible with previously described algorithms. We apply these algorithms to natural images and demonstrate that the inferred sparse codes exhibit end-stopping and non-classical receptive field surround suppression and, therefore, may provide a partial explanation for these two phenomena in V1 neurons.   Sparse coding is a very interesting idea that Dwave Systems been experimenting with on their adiabatic quantum computer. Sparse coding is a way to find 'maximally repeating patterns' in data, and use these as a basis for representing that data. Sparse coding is probably related to how human perception and cognition functions.

"Basically convertible is possible in five years, but it might not be 100 percent convertible." London is racing against Paris and Zurich to become the center for yuan trading in Europe as China seeks to take its currency global.
