Today, the arterial switch operation is the treatment of choice for patients with transposition of the great arteries. Midterm follow-up confirms the initial hopes for good systemic ventricular function and lack of arrhythmias. A two-stage operation can be performed in patients seen after 1 month of age or in subjects who have had an atrial switch operation and with late systemic dysfunction. Increasing experience with the arterial switch operation has led to its successful use in more complex lesions. Increased mortality and morbidity after the atrial switch operation has been confirmed, with decreased cardiac output, baffle obstruction, and arrhythmias. In some cases interventional catheterization is useful. In patients with corrected transposition of the great arteries who have associated malformations, the poor midterm results seen with the classical surgical repair make the combined atrial and arterial switch an interesting option.

Irish residential heating demand profile dataset.
Data Brief
February 2025
Economic and Social Research Institute, Dublin, Ireland.
This data article describes the operation of gas and oil fuelled residential heating systems in Ireland. Based on almost 10,000 homes, the data presents information on the operation of domestic heating systems (whether turned on/off by the user), and the firing of the boiler during 2-hour slots across a period of two years ending in September 2021 by geographical region. The electrification of heating is government policy, with the ambition that hundreds of thousands of homes will switch from oil and gas fuelled residential heating to heat pumps.

Background: Each year, nearly 400,000 new cases of paediatric hydrocephalus are estimated to occur worldwide, and almost half of these cases are expected to affect children in Africa. At Queen Elizabeth Central Hospital (QECH), an urban tertiary hospital in Blantyre, Malawi, located in south-east Africa, around 200 children received neurosurgical treatment for hydrocephalus in 2023. These children require lifelong follow-up and care, which places significant demands on their caregivers.

Dynamic control of DNA circuit functionality is essential for constructing chemical reaction networks (CRNs) that implement complex functions. The triplex has been utilized for dynamically regulating the diverse functionalities of DNA circuits due to its distinctive pH responsiveness. However, it is challenging for triplexes to independently regulate the functionality of DNA circuits, as various triplexes were often required for DNA circuits to function in complex environments, which adds complexity to the design and control of dynamic circuits.

A large aperture (800µm) is achieved by strategically positioning pixel electrodes on either side of the LC lens and auxiliary electrodes at its center. This design effectively doubles the LC lens aperture compared to conventional structures, achieving this at a significantly lower voltage.
