Deviations from Brownian motion leading to anomalous diffusion are ubiquitously found in transport dynamics, playing a crucial role phenomena quantum physics life sciences. The detection and characterization of the measurement an individual trajectory challenging tasks, which traditionally rely on calculating mean squared displacement trajectory. However, this approach breaks down for cases important practical interest, e.g., short or noisy trajectories, ensembles heterogeneous non-ergodic...

The 2030 Agenda of the United Nations (UN) revolves around Sustainable Development Goals (SDGs). A critical step towards that objective is identifying whether scientific production aligns with SDGs' achievement. To assess this, funders and research managers need to manually estimate impact their funding agenda on SDGs, focusing accuracy, scalability, objectiveness. With this in mind, work, we develop ASDG, an easy-to-use Artificial-Intelligence-based model for automatically potential papers...

Abstract The results of the Anomalous Diffusion Challenge (AnDi Challenge) (Muñoz-Gil G et al 2021 Nat. Commun. 12 6253) have shown that machine learning methods can outperform classical statistical methodology at characterization anomalous diffusion in both inference exponent α associated with each trajectory (Task 1), and determination underlying diffusive regime which produced such trajectories 2). Furthermore, five teams finished top three across tasks AnDi Challenge, those used...

Anomalous diffusion is characterized by nonlinear growth in the mean square displacement of a trajectory. Recent advances using statistical methods and recurrent neural networks have made it possible to detect such phenomena, even noisy conditions. In this work, we explore feature extraction through parametric non-parametric spectral analysis decode anomalously diffusing trajectories, achieving reduced computational costs compared with other approaches that require additional data or prior...

Anomalous diffusion is present at all scales, from atomic to large ones. Some exemplary systems are ultracold atoms, telomeres in the nucleus of cells, moisture transport cement-based materials, arthropods' free movement, and birds' migration patterns. The characterization gives critical information about dynamics these provides an interdisciplinary framework with which study diffusive transport. Thus, problem identifying underlying regimes inferring anomalous exponent α high confidence...

Abstract Anomalous diffusion occurs at very different scales in nature, from atomic systems to motions cell organelles, biological tissues or ecology, and also artificial materials, such as cement. Being able accurately measure the anomalous exponent associated a given particle trajectory, thus determining whether subdiffuses, superdiffuses performs normal diffusion, is of key importance understand process. Also it often important trustingly identify model behind this gives large amount...
