Compact Object Mergers: Population Astrophysics and Statistics (COMPAS; https://compas.science) is a public rapid binary population synthesis code. COMPAS generates populations of isolated stellar binaries under a set of parameterized assumptions in order to allow comparisons against observational data sets, such as those coming from gravitational-wave observations of merging compact remnants. It includes a number of tools for population processing in addition to the core binary evolution components. COMPAS is publicly available via the GitHub repository https://github.com/TeamCOMPAS/COMPAS/, and is designed to allow for flexible modifications as evolutionary models improve. This paper describes the methodology and implementation of COMPAS. It is a living document that will be updated as new features are added to COMPAS; the current document describes COMPAS v02.21.00.

ST‐segment elevation myocardial infarction (STEMI) is associated with increased mortality and morbidity. Although remarkable progress has been made in the management of STEMI in high‐income countries, contemporary data to evaluate processes and outcomes of STEMI care in India is limited. The North Indian ST‐segment elevation myocardial infarction (NORIN STEMI) registry is a prospective cohort study based at government funded and largely free of cost tertiary medical centers in New Delhi, India. These hospitals serve a large proportion of the patients with lower socioeconomic status presenting from multiple states in India, as many centers in these states lack adequate specialized cardiovascular care. The study has been approved by the Institutional Review Boards of each institution and informed consent has been obtained from study participants. The NORIN STEMI registry aims to provide important insights regarding contemporary risk factors profiles, practice patterns, and prognosis in patients with STEMI in an underserved population in North India. These findings may identify opportunities to improve the outcomes of patients with STEMI in India.

The public COMPAS code is a product of work by the entire COMPAS collaboration over many years; we therefore kindly request that, in recognition of this team effort, the paper is cited as Team COMPAS -J. Riley et al.
