The result says that convolutions are somewhat ‘continuous’ objects: one can find lots of translates that leave f ∗ g virtually unchanged in L; furthermore, there is a lot of structure to the set of translates. For the reader unfamiliar with Bohr sets, we give the definition and the relevant properties in the next section; the general idea to take away is that B can be considered a ‘large’ and ...

We investigate the distribution of the Riemann zeta-function on the line Re(s) = σ. For 1 2 < σ ≤ 1 we obtain an upper bound on the discrepancy between the distribution of ζ(s) and that of its random model, improving results of Harman and Matsumoto. Additionally, we examine the distribution of the extreme values of ζ(s) inside of the critical strip, strengthening a previous result of the first ...

Global health networks—webs of individuals and organizations linked by a shared concern for a particular condition—have proliferated over the past quarter century. In a recent editorial in this journal, I presented evidence that their effectiveness in addressing four challenges—problem definition, positioning, coalitionbuilding and governance—shapes their ability to influence policy. The editor...

the objective of this paper is to provide an overview of various approaches on iran’s nuclear program and the frameworks within which the approaches can be located. it first addresses different views held in relevant think tanks and academic circles in the u.s. regarding iran’s nuclear program, including motivation-based and consequence-based arguments in their different variants. then iranians...
