Mathematician's study of 'swarmalators' could direct future science | EurekAlert! Science News: Strogatz and Kevin O'Keeffe, Ph.D. '17, used the curious mating ritual of male Japanese tree frogs as inspiration for their exploration of "swarmalators" - their term for systems in which both synchronization and swarming occur together.

Specifically, they considered oscillators whose phase dynamics and spatial dynamics are coupled. In the instance of the male tree frogs, they attempt to croak in exact anti-phase (one croaks while the other is silent) while moving away from a rival so as to be heard by females.

This opens up "a new class of math problems," said Strogatz, a Stephen H. Weiss Presidential Fellow. "The question is, what do we expect to see when people start building systems like this or observing them in biology?"

Their paper, "Oscillators That Sync and Swarm," was published Nov. 13 in Nature Communications. Strogatz and O'Keeffe - now a postdoctoral researcher with the Senseable City Lab at the Massachusetts Institute of Technology - collaborated with Hyunsuk Hong from Chonbuk National University in Jeonju, South Korea.

In 1987, the Soviet ambassador to the United Nations, Yuri Dubinin, arranged for Trump and his then-wife, Ivana, to enjoy an all-expense-paid trip to Moscow to consider possible business prospects. Only seven weeks after his trip, Trump ran full-page ads in the Boston Globe, the NYT and WaPO calling for, in effect, the dismantling of the postwar Western foreign policy alliance. The whole Trump/Russian connection started out as laundering money for the Russian mob through Trump's real estate, but evolved into something far bigger. ► In 1984, David Bogatin — a Russian mobster, convicted gasoline bootlegger, and close ally of Semion Mogilevich, a major Russian mob boss — met with Trump in Trump Tower right after it opened. Bogatin bought five condos from Trump at that meeting. Those condos were...
