Mathematics Tue, 18 Jun 2019 07:14:46 EDTnews480060876The hidden structure of the periodic systemThe periodic table of elements that most chemistry books depict is only one special case. This tabular overview of the chemical elements, which goes back to Dmitri Mendeleev and Lothar Meyer and the approaches of other chemists to organize the elements, involve different forms of representation of a hidden structure of the chemical elements. This is the conclusion reached by researchers at the Max Planck Institute for Mathematics in the Sciences in Leipzig and the University of Leipzig in a recent paper. The mathematical approach of the Leipzig scientists is very general and can provide many different periodic systems depending on the principle of order and classification—not only for chemistry, but also for many other fields of knowledge.

A new paper in the Proceedings of the National Academy of Sciences (PNAS) suggests that one of these old approaches is more practical than previously realized.

The technique consists of adding a constant parameter to the "analytic signals" in a way that emphasizes certain aspects of their timing. This could improve brain-computer interfaces designed to aid disabled people.

Even though the sandpile model serves as the archetypal model to study self-organized criticality, questions about its characteristics are still open and remain an active field of research.

Frogs communicate with sound, and amid their ruckus is an internally orchestrated system that lets information get through more clearly while also permitting collective choruses and time to rest. Researchers from Osaka University and University of Tsukuba sought to leverage this amphibious acumen for mathematical and technological aims.

The objects resemble geometric sculptures that might be found in a modern art museum, but it is the motions they undergo that really capture the imagination. Ring linkages, constructed from hinges and rigid geometric shapes, can be turned inside-out continuously, reminiscent of a flower bud blooming over and over again. The mesmerizing objects inspire wonder in all those who see them, including curious engineers and mathematicians.

But only some of that information is meaningful, in that it actually helps the fish survive. In various disciplines, from biology to artificial intelligence, identifying such meaningful, or "semantic," information is a key challenge. Yet a broadly applicable, fully formal definition of this kind of information has never been developed.
