The Astrophysical Journal, 2023 Lower hybrid waves are commonly observed in magnetic reconnection. Based on in situ measurements and the application of an extended quasi-linear model, we investigate the occurrence, saturation, and electron heating of lower hybrid waves in the region of

GeoJournal, 2021 Participatory mapping approaches have raised increasing interest in a variety of fields of research and practice during the past two decades. However, their use in modeling and studying individual mobility and activity spaces is rather recent and limited.

Learning to Control Active Matter [PDF]
Phys. Rev. Research 3, 033291 (2021), 2021 The study of active matter has revealed novel non-equilibrium collective behaviors, illustrating their potential as a new materials platform. However, most works treat active matter as unregulated systems with uniform microscopic energy input, which we refer to as activity.

Planetary-scale MLT waves diagnosed through multi-station methods: a review
Earth, Planets and Space, 2023 Most experimental investigations on planetary-scale waves in the mesosphere and lower thermosphere (MLT) region are based on single-station or -satellite spectral analysis methods, which suffer from intrinsic spectral aliasing/ambiguity.

Active Space Pair 2-Electron Reduced Density Matrix Theory for Strong Correlation [PDF]
J. Phys. Chem. A 124, 4848-4854 (2020), 2020 An active space variational calculation of the 2-electron reduced density matrix (2-RDM) is derived and implemented where the active orbitals are correlated within the pair approximation. The pair approximation considers only doubly occupied configurations of the wavefunction which enables the calculation of the 2-RDM at a computational cost of ...

Beyond Activity Space: Detecting Communities in Ecological Networks. [PDF]
Ann Am Assoc Geogr, 2020 Emerging research suggests that the extent to which activity spaces—the collection of an individual’s routine activity locations—overlap provides important information about the functioning of a city and its neighborhoods.

Linear Scaling Calculations of Excitation Energies with Active-Space Particle-Particle Random Phase Approximation [PDF]
, 2023 We developed an efficient active-space particle-particle random phase approximation (ppRPA) approach to calculate accurate charge-neutral excitation energies of molecular systems. The active-space ppRPA approach constrains both indexes in particle and hole pairs in the ppRPA matrix, which only selects frontier orbitals with dominant contributions to ...

Association Between the Activity Space Exposure to Parks in Childhood and Adolescence and Cognitive Aging in Later Life. [PDF]
Int J Environ Res Public Health, 2019 The exposure to green space in early life may support better cognitive aging in later life. However, this exposure is usually measured using the residential location alone.
