Time crystals sound like something out of science fiction, but they may be the next major leap in quantum network research. A team based in Japan has proposed a method to use time crystals to simulate massive networks with very little computing power. They published their results on October 16 Science Advances.
Researcher makes 'little data' act big through, the application of mathematical techniques normally used for time-series, to spatial processes. The study, 'An information-theoretic approach to study spatial dependencies in small datasets,' featured on the cover of Proceedings of the Royal Society.
Contagion processes, such as opinion formation or disease spread, can reach a tipping point, where the contagion either rapidly spreads or dies out. When modeling these processes, it is difficult to capture this complex transition. In the journal Chaos, researchers studied the parameters of these transitions by including three-person group interactions in a contagion model called the susceptible-infected-susceptible model. In this model, an infected person who recovers from an infection can be reinfected.
In an article published in Nature on October 14, 2020, scientists at Princess Margaret Cancer Centre, University of Toronto, Stanford University, Johns Hopkins, Harvard School of Public Health, Massachusetts Institute of Technology, and others, challenge scientific journals to hold computational researchers to higher standards of transparency, and call for their colleagues to share their code, models and computational environments in publications.
Researchers at Institut national de la recherche scientifique (INRS) have discovered a cost-effective way to tune the spectrum of a laser to the infrared, a band of great interest for many laser applications. They collaborated with Austrian and Russian research teams to develop this innovation, which is now the subject of a patent application. The results of their work were recently published in Optica, the flagship journal of the Optical Society (OSA).
A new set of assessment tools shows promise in capturing how the COVID-19 pandemic affects patterns of criminal activity. Hervé Borrion of University College London, U.K., and colleagues present this toolkit in the open-access journal PLOS ONE on October 14.
Northwestern University researchers have developed the first quantitative model that captures how politicized environments affect U.S. political opinion formation and evolution.
"Flutter" is a complex oscillatory phenomenon that can destroy aircraft turbine blades and has historically been the cause of several plane accidents. Now, scientists at Tokyo University of Science and the Japan Aerospace Exploration Agency explore a novel approach that can be used to early detect the onset of flutter, solving one of the main problems that has been holding back the design of lighter and more efficient turbines.
The international collaborative team has discovered for the first time a topological change of a classical interfacial hydrodynamics, which is driven by 'a partially miscibility'. This phenomenon cannot be seen in completely mixed (fully miscible) system with infinite solubility or immiscible system with no solubility.
Cloaking a concentrator in thermal conduction via topology optimization. A simultaneous cloaking and concentrating of heat flux is achieved through topology optimization, a computational structural design methodology.
