A team including researchers from Osaka University looked to nature for inspiration in designing more effective wireless sensor networks. First, they recorded the vocal interplay of neighboring tree frog calls, which they found allowed tradeoff time for individual communication, though this is interspersed with more random collective silence and choruses. They mathematically modeled these patterns and effectively applied their model toward the control of a wireless sensor network.
Dr. Teruyoshi Kobayashi of Kobe University and his team developed a new method for identifying individuals that have essential connections between them -- what they call 'significant ties'. Dr. Kobayashi says: "The point is that we need to distinguish between the contact events that could happen by chance and the events that would not happen without a significant relationship between two individuals." Their findings were published in Nature Communications on January 15.
In a study published in Physical Review E, physicists analyzed the Rossler system, a well-known chaotic system which physicists have studied thoroughly for almost 40 years. Looking at this system from a fresh perspective, they discovered new phenomena that have been overlooked until now. For the first time the researchers were able to measure the fine grain process that leads from disorder to synchrony, discovering a new kind of synchronization between chaotic systems.
One of the first studies to examine how climate is influencing functional traits in forest communities on a global scale found evidence of major changes.
A recent study published in iScience researchers at Kanazawa University describes the role of a molecule, Netrin, in creating borders inside the brain to compartmentalize the functions of the brain.
Researchers introduce a curious new class of linkage which could be used in everything from fundamental research to synthetic chemistry to robotics.
When making sense of the massive amount of information packed into an ice core, scientists face a forensic challenge: how best to separate the useful information from the corrupt. Tools from information theory, a branch of complexity science, can quickly flag which segments, in over a million data points, require further investigation.
One transistor, just a pair of inductors and capacitors. Such a simple electronic circuit can become an oscillator with a surprising richness of behavior. However, even more interesting effects become visible if the structure of connections is fractal and shows some... imperfections. Could similar rules explain the diversity and complexity of the human brain dynamics?
Researchers from NYU Tandon School of Engineering and Politecnico di Torino, Italy, have developed a mathematical model that could cure the potential to underestimate how quickly diseases spread. The team discovered that current predictive models may miss the influence of a critical aspect of the social behavior of individuals called 'burstiness.'
Northwestern Engineering's Noshir Contractor and researchers analyzed game statistics across major sports and online games, revealing that past shared success among teammates improves their team's odds of winning future games.
