Published in 2021 at "Pediatric Pulmonology"

DOI: 10.1002/ppul.25812

Abstract: Inhaled bronchodilators are often given in preterm infants with evolving or established bronchopulmonary dysplasia. However, it is unclear which patients may benefit from it and when it is the best time to start treatment. The… read more here.

Published in 2024 at "Pediatric Pulmonology"

DOI: 10.1002/ppul.27415

Abstract: Spirometry is the gold standard for assessing airway function for clinical studies; however, obtaining high‐quality data in young children remains challenging. Since the forced oscillation technique (FOT) requires less subject cooperations, there has been increasing… read more here.

Published in 2019 at "Archivos de bronconeumologia"

DOI: 10.1016/j.arbres.2019.01.022

Abstract: OBJECTIVE Hypersensitivity pneumonitis (HP) is an interstitial lung disease caused by the inhalation of specific organic antigens or low-molecular weight substances in genetically susceptible individuals. Although small airway involvement is prominent in patients with chronic… read more here.

Published in 2022 at "Physiological Measurement"

DOI: 10.1088/1361-6579/ac522e

Abstract: Objective. The assessment of lung mechanics in horses is nowadays based on invasive methods that may require sedation. The forced oscillation technique (FOT) allows the non-invasive assessment of respiratory mechanics during spontaneous breathing, but current… read more here.

Published in 2024 at "Physical Review D"

DOI: 10.1103/bwrd-v7b4

Abstract: The basic framework of the superfluid vortex model for pulsar glitches, though, is well accepted; there is a lack of consensus on the possible trigger mechanism responsible for the simultaneous release of a large number… read more here.

Published in 2020 at "IEEE Transactions on Control Systems Technology"

DOI: 10.1109/tcst.2019.2898836

Abstract: This brief proposes a tuning methodology for proportional-resonant (PR) controllers by using the design philosophy of the Ziegler–Nichols forced oscillation method. Unlike such related methods that are usual for proportional–integral–differential design, and those that have… read more here.

Published in 2021 at "IEEE Transactions on Power Systems"

DOI: 10.1109/tpwrs.2020.3009422

Abstract: Forced oscillation (FO) has recently been detected in power grids, e.g., Nordic and Western American power systems. It has been reported that the FO is excited by forced disturbances, which consist of the frequencies nearly… read more here.
