What Is the Probability Your Vote Will Make a Difference?

One of the motivations for voting is that one vote can make a difference. In a presidential election, the probability that your vote is decisive is equal to the probability that your state is necessary for an electoral college win, times the probability the vote in your state is tied in that event. We computed these probabilities a week before the 2008 presidential election, using state-by-stat...

Make junction, will travel

ny cell therapy risks introducing mutated and possibly tumorigenic cells. Now results from Peter Stambrook (University of Cincinnati, Cincinnati, OH) and colleagues underline this concern for embryonic stem (ES) cells, which are one possible source for therapeutic cells. Stambrook constructed a cell line in which he could detect loss or mutation of a heterozygous marker gene. Loss (rather than ...

Towards Sustainable Development of Energy-Aware Systems

Smart devices have pervaded our society and encouraged lifestyles that depend on them. One of the fundamental requirements for a successful dependency is that the general public be aware of the energy limitations of these devices and to stay in control of energy consumption. In this paper, the authors propose a formal specification method that takes energy into account. They propose two develop...

Integrated Design of Dynamic Sustainable Energy Systems

Recent advancements in the development and investigation of integrated methods for the design of dynamic engineering systems have made possible the achievement of new levels of system performance and now support the ability to systematically identify synergy mechanisms that can improve the effectiveness of system design processes at both early and late stages. Significant efforts in the last se...
