DOI: 10.1016/j.enconman.2021.114246

Abstract: Abstract Usually conventional nonlinear tri-stable piezoelectric energy harvesters (TPEHs) contain two external magnets, which make both the system structure and dynamic analysis more complex. Herein, a novel dual-magnet TPEH with only one external magnet is… read more here.

DOI: 10.1088/1361-665x/ad8b88

Abstract: Inspired by the Kresling origami structure and its three stable state characteristics, a novel multimodal continuum robot (MCR) has been proposed in this paper, which achieve its own movement through gas-driven and actively elastic deformed… read more here.

DOI: 10.1093/mmy/myab070

Abstract: Pneumocystis jirovecii colonisation is frequent during COPD and patients constitute potential contributors to its interhuman circulation. However, the existence of an environmental reservoir cannot be excluded. We assessed the prevalence and factors associated with Pneumocystis… read more here.

DOI: 10.1183/23120541.00057-2022

Abstract: Background The burden of chronic obstructive pulmonary disease (COPD) in the Asia-Pacific region is projected to increase. Data from other regions show bacterial and viral infections can trigger acute exacerbations of COPD (AECOPD). Methods This… read more here.

DOI: 10.1186/s12890-024-02888-z

Abstract: Background Elevation of systemic inflammatory markers were found to correlate with increased disease extent, reduced lung function and higher risk of future severe exacerbations in patients with bronchiectasis. Although a significant correlation of circulating hs-CRP… read more here.
