from the early 1950s, estimating the autocorrelations of polynomials with coefficients on the unit circle has found applications in ising spin systems and in surface acoustic wave designs. in this paper, a technique is introduced that not only estimates the autocorrelations, but for some special types of such polynomials, it locates the frequencies at which maximum autocorrelation occurs.

The challenges of resistance to antibiotics and herbicides have much in common. Antibiotic became a risk the 1950s, but concerted global effort manage it did not begin until after 2000. Widespread herbicide use began during 1950s was soon followed by an unabated rise resistance. Here, we examine what lessons for combatting could be learnt from global, coordinated efforts all stakeholders avert ...

The article retraces major events and milestones in the mutual influences between mathematical logic and computer science since the 1950s.

[1] The sea surface temperatures (SSTs) of the tropical Indian Ocean show a pronounced warming since the 1950s. We have analyzed the impact of this warming on Sahelian rainfall and on the North Atlantic Oscillation (NAO) by conducting ensemble experiments with an atmospheric general circulation model. Additionally, we investigate the impact of the other two tropical oceans on these two climate ...
