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 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 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 2020 at "IEEE Transactions on Power Systems"

DOI: 10.1109/tpwrs.2020.2994855

Abstract: Wide-area time-synchronized measurements have recently revealed troublesome forced oscillations (FOs) within modern synchronized power grids. In some cases, these FOs represent a dangerous hazard to the system. Recent research has focused on locating the source… 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.

Published in 2018 at "Geophysical Prospecting"

DOI: 10.1111/1365-2478.12710

Abstract: 13 Fluid pressure diffusion occurring on the microscopic scale is believed to be a significant 14 source of intrinsic attenuation of seismic waves propagating through fully saturated porous 15 rocks. The so-called squirt flow arises… read more here.

Published in 2018 at "Respirology"

DOI: 10.1111/resp.13186

Abstract: Selecting ‘healthy’ preschool‐aged children for reference ranges may not be straightforward. Relaxing inclusion criteria for normative data does not affect spirometry z‐scores. We therefore investigated the effect of similarly relaxing inclusion criteria in preschoolers on… read more here.

Published in 2019 at "Journal of applied physiology"

DOI: 10.1152/japplphysiol.00534.2018

Abstract: Derecruitment of air spaces in the lung occurs when airways close during exhalation and is related to ventilation heterogeneity and symptoms in asthma. The forced oscillation technique has been used to identify surrogate measures of… read more here.
