    The global network of gravitational-wave observatories now includes five detectors, namely LIGO Hanford, LIGO Livingston, Virgo, KAGRA, and GEO 600. These detectors collected data during their third observing run, O3, composed of three phases: O3a starting in 2019 April and lasting six months, O3b starting in 2019 November and lasting five months, and O3GK starting in 2020 April and lasting two weeks. In this paper we describe these data and various other science products that can be freely accessed through the Gravitational Wave Open Science Center at https://gwosc.org. The main data set, consisting of the gravitational-wave strain time series that contains the astrophysical signals, is released together with supporting data useful for their analysis and documentation, tutorials, as well as analysis software packages

    Asthma and chronic obstructive pulmonary disease (COPD) are obstructive airway diseases that involve chronic inflammation of the lower respiratory tract. They differ from each other in the pattern of inflammation, their immunologic mechanisms, the extent of reversibility of airflow limitation, and their inciting agents (allergens in the case of asthma and cigarette smoke in the case of COPD). Additional differences in diagnostic workup, treatment, and monitoring have warranted the development and implementation of separate guidelines for the diagnosis and management of these conditions. However, evidence is accumulating that asthma and COPD share common pathogenetic pathways. In particular, genetic studies investigating . . .
