Network of sounds: New research reveals the magic secret of human networksA group of Israeli researchers recruited 16 violinists to study the behavior of a human network and find out what sets it apart from other networks, such as animals, computers, and other objects. The results combine science and esthetics, and also evoke thoughts about the spread of the coronavirus.

And despite the choice by all US states to gradually ease lockdown from late May onwards to save the economy, 14 million Americans have lost their job, while the economic output in the second quarter of 2020 dropped by 9.5%. To help entrepreneurs decide on how they can safely reopen their business, mathematicians and statisticians here develop a model for the spread of infections within companies and the economic payoff of safety measures. Their findings are published today in Frontiers in Applied Mathematics and Statistics.

Mathematics Economics & Business Tue, 11 Aug 2020 00:20:01 EDTnews516289090Q&A: What's math got to do with peace?Larry Liebovitch is a professor in the Department of Physics and the Department of Psychology at Queens College, and at the Physics Program of the Graduate Center, City University of New York. He is also a core faculty member of the Sustaining Peace Project at the Earth Institute's Advanced Consortium on Cooperation, Conflict, and Complexity (AC4). He recently developed a mathematical model simulation of sustainable peace in a society. In this mathematical model, users respond to a series of questions about a community by plugging in values for different factors that research suggests are important to sustaining peace. Examples of these factors include the degree to which leaders model peaceful values and the degree to which information flows freely between members of all groups in a society. The model then shows where the system of factors might end up over time—heading to war or situated in peace—offering a tool for the public to think about possible paths to sustaining peace.

Radboud mathematician Walter van Suijlekom explains in a new publication in the journal Communications in Mathematical Physics on 14 July. "We can compare this to MP3s: with a limited range of sound waves, we easily get the impression we are listening to an analogue recording of music." This finding eventually means that we should be able to calculate the shape of our universe.

As weeks pass by, we learn more and more about this little virus, which affects our everyday lives and our world so much. In the biocomplexity section at the Niels Bohr Institute (NBI), University of Copenhagen, the researchers are busy applying methods from the physics of complex systems to examine how the epidemic is best handled. The, by now, well known and simplest manner is the "lock down," which we've been going through during the months of March and April. It is also the most expensive, it proved to be efficient, something we couldn't know before testing it. But there are many ways of calculating and forecasting the development of the epidemic, and the researchers in biocomplexity and complex systems explain one of them here, as well as some of the most prevalent concepts presented in the media.

Minecraft is a sandbox video game released in 2011, where the gamer can build almost anything, from simple houses to complex calculators, using only cubes and fluids. These countless possibilities are what lured David Strütt into Minecraft's universe: "the game might be first intended for kids but I was studying for my Bachelor's degree in mathematics when I discovered it. I fell in love with the game when I realized there is all the necessary blocks to build a Turing machine inside the game. It was a long time ago, so I have since forgotten what a Turing machine is. But the gist of it is: anything is possible inside the game."

The use of statistical methods utilizing correlation matrices to analyze the hundred most-traded virtual currencies shows that the cryptocurrency market in the last two years is less and less different from the mature global currency market (Forex) and becomes independent of it. It means cryptocurrencies can be considered a serious and full-fledged financial instrument.

Mathematics Economics & Business Thu, 02 Apr 2020 12:28:50 EDTnews505049325Representation of driving behavior as a statistical modelA joint research team from Toyohashi University of Technology, Department of Architecture and Civil Engineering, Toyota Transportation Research Institute, and Daido University has established a method to represent driving behaviors and their changes that differ among drivers in a single statistical model, taking into account the effect of various external factors such as road structure. This method was applied to measure the effectiveness of Intelligent Speed Adaptation (ISA), which controls excessive speed violations. As a result, the research team found that in some cases, it is effective for drivers with a high tendency of frequent excessive speeding, and in other cases, effective only for elderly drivers depending on the style of the ISA. This method can be applied not only to ISA but also to measure the effectiveness of traffic safety management technologies that encourage drivers to change their various driving behaviors.
