Researchers discover that most typical networks are robust to both random and deliberate attacks, contrary to previous thought. They propose a simple method to explore the mathematical space of all interesting networks with a particular node degree distribution.
A new algorithm developed by Hua-Wei Shen helps accurately allocate credit to researchers based on their contributions. The algorithm, which has been tested on 63 Nobel prize-winning papers, found that authors deserving of the most credit corresponded to the Nobel laureate in 81% of cases.
The paper proposes a formal passive testing approach to evaluate the conformance and performance of Extensible Messaging and Presence Protocol (XMPP) in IoT environments. The approach uses Horn clauses to express properties checked on extracted protocol traces, enabling the testing of individual nodes in complex networks.
Researchers found that temporal characteristics, particularly bursts of activation events, significantly impact diffusion processes. This new understanding can help build more accurate metrics for analyzing real-world network data.
Brazilian physicists Thiago Silva and Diego Amancio devised a method to disambiguate words with multiple meanings by analyzing their connections in literary classics. Their approach, based on deterministic tourist walks, showed significant accuracy rates comparable to traditional semantic-based methods.
Researchers at Northwestern University developed a computational framework to control large complex networks by identifying small perturbations that can rescue or reprogram them. The approach has been successfully applied to mitigate cascading failures in power-grid networks and identify potential drug targets in human cancer.
Complex networks from different disciplines exhibit similar core structures, known as skeletons, which are shaped by basic growth mechanisms. This discovery could help predict how diseases or information spread across networks.
Researchers at Northwestern University develop a new theory of networks, establishing relationships between disparate topics such as friendship paradoxes and material properties. The study reveals that cascading processes can be controlled and collective behavior depends on network properties, opening new avenues for disease treatment ...
North American cuisine tends to share more flavor compounds than expected, with ingredients like milk and butter contributing positively to food pairing. In contrast, East Asian cuisine often avoids mixing ingredients with shared flavor compounds, such as beef and ginger, which may negatively impact food pairing.
Researchers found that higher disorder in complex networks accelerates synchronisation, contradicting previous theories. This observation holds true for various real-life networks, including air-transport and social networks.
Scientists developed a mathematical model to describe interactions within ecological food webs, illustrating how human intervention can aid species conservation. The study found that over 70% of extinctions are preventable by balancing the system with available resources.
A team of scientists has made significant progress in understanding how the brain's 'hearing center' processes sound by mapping its acoustic space.
