Array programming provides a powerful, compact, expressive syntax for accessing, manipulating, and operating on data in vectors, matrices, and higher-dimensional arrays. NumPy is the primary array programming library for the Python language. It plays an essential role in research analysis pipelines in fields as diverse as physics, chemistry, astronomy, geoscience, biology, psychology, material science, engineering, finance, and economics. For example, in astronomy, NumPy was an important part

Here we show how a few fundamental array concepts lead to a simple and powerful programming paradigm for organizing, exploring, and analyzing scientific data. NumPy is the foundation upon which the entire scientific Python universe is constructed. It is so pervasive that several projects, targeting audiences with specialized needs, have developed their own NumPy-like interfaces and array objects. Because of its central position in the ecosystem, NumPy increasingly plays the role of an interoperability layer between these new array computation libraries.

Minna Mecklin, Paula Heikkilä, Matti Korppi
2018 European Journal of Pediatrics  
In the PICU, non-invasive ventilation therapies increased significantly, but intubation rates did not decline.  ...  Median hospital length of stay for PICU patients were 7 days (interquartile range 5-12), 5 days (4-8) and 8 days (4-12.5, p = 0.127), respectively.  ...  Matti Korppi was responsible on study design and interpretation of data and had substantial contribution on writing the article.  ...

Low age, low birthweight and congenital heart disease are risk factors for intensive care in infants with bronchiolitis

Conclusion: Less than 0.1% of infants under the age of 12 months were admitted to the PICU for bronchiolitis.  ...  Results: The average age-specific annual incidence of bronchiolitis requiring PICU admission under the age of 12 months was 1.5/1,000/year (range 0.18-2.59).  ...  The controls were not admitted to the PICU and 146 of them were treated as inpatients on the ward and 64 as outpatients in the ED and were not admitted to the PICU.  ...

Prolonged outbreak of Serratia marcescens in Tartu University Hospital: a case–control study

Vivika Adamson, Piret Mitt, Heti Pisarev, Tuuli Metsvaht, Kaidi Telling, Paul Naaber, Matti Maimets
2012 BMC Infectious Diseases  
The study was conducted in two units: a 9-bed PICU and a 24-bed NU, which serve 300 and 800 admissions per year, respectively. Approximately 2/3 of PICU patients are neonates and 1/3 older children.  ...  If the condition should worsen, neonates can be transferred back to PICU. Neonatologists and trained neonatal nurses work in the units.  ...
