    An Adiabatic-Expansion-Induced Perturbation Study on Gas–Aerosol Partitioning in Ambient Air—Formation of NH<sub>4</sub>NO<sub>3</sub> and Microdroplet Nitrogen Fixation (2) by Yating Gao, Qinchu Fan, Yujiao Zhu, Hengqing Shen, Qi Yuan, Yang Gao, Huiwang Gao, Xiaohong Yao

    Published 2025-05-01
    “…Our results indicate the adiabatic-expansion-induced generation of NH<sub>3</sub> + HNO<sub>3</sub> at ultrafast formation rates, with campaign-dependent stable stoichiometric ratios of HNO<sub>3</sub> to NH<sub>3</sub>, as well as highly variable occurrence frequencies and efficiencies. These findings suggest that microdroplet redox reactions are more likely responsible for the generation of NH<sub>3</sub> + HNO<sub>3</sub> than conventional atmospheric NH<sub>3</sub> chemistry. …”

    Time-varying MVAR algorithms for directed connectivity analysis: Critical comparison in simulations and benchmark EEG data. by Mattia F Pagnotta, Gijs Plomp

    Published 2018-01-01
    “…Results from numerical simulations and from benchmark EEG recordings showed that: i) across a broad range of model orders all algorithms correctly reproduced patterns of interactions; ii) signal downsampling degraded connectivity estimation accuracy for most algorithms, although in some cases downsampling was shown to reduce variability in the estimates by lowering the number of parameters in the model; iii) single-trial modeling followed by averaging showed optimal performance with larger adaptation coefficients than previously suggested, and showed slower adaptation speeds than multi-trial modeling. …”
