Scientists in Vienna have studied the complex interplay between flooding events and economic decisions. Private businesses should not shoulder the responsibility for flood protection alone. In prosperous countries in particular, it makes sense for central government to establish the necessary infrastructure for flood protection.
Weather patterns, brain activity and heartbeats each generate lines of complex data. To analyze this data, researchers must first divide up this continuous data into discrete pieces -- a task difficult to perform simply and accurately. Researchers have devised a method to transform data from complex systems, reducing the amount of important information lost, while still using less computing power than existing methods. They describe this new method in the current issue of Chaos.
Scientists at the John Innes Centre have come up with a novel way of quantifying cell shapes -- with a lot of mathematics and a little musical inspiration.
Sudden unexpected death of infants (SUDI) was the most common cause of infant mortality among children born full term in the US according to estimates from a state-by-state study published this week in PLOS Medicine.
Army and university scientists are turning to problems with social media to create social sensing as a scientific discipline. For the Army in particular, this emerging science space, they say, will better help commanders assess and comprehend the accuracy and true meaning of information on the battlefield.
Information scientists at the U.S. Army Research Laboratory and the University of Michigan have borrowed from the popular game "20 Questions," to make an important step towards helping robots maintain continuous and purposeful conversation with humans. They have developed an optimal strategy for asking a series of yes/no questions that rapidly achieves the best answer.
Surprisingly, a quintessential equation of quantum mechanics emerges while studying astronomical disks of orbiting material.
The average rate at which Americans tip for services has been increasing steadily for decades, but the practice has been branded over the years as classist, anti-egalitarian, and downright undemocratic, leading some restaurateurs to abandon it. A new paper, drawing insight from nonlinear dynamics and published in the journal Chaos, hopes to shed light on the economically irrational world of tipping, showing that at a certain point, banning the practice might be fair and profitable.
The same techniques used to train self-driving cars and chess-playing computers are now helping physicists explore the complexities of the quantum world. For the first time, physicists have demonstrated that machine learning can reconstruct a quantum system based on relatively few experimental measurements. This method will allow scientists to thoroughly probe systems of particles exponentially faster than conventional, brute-force techniques.
Most election polls take the political pulse of a state or nation by reaching out to citizens about their voting plans. Santa Fe Institute Professor Mirta Galesic says pollsters might also ask: how do your friends plan to vote?
