Article Synopsis
- The study aims to understand the language used around dying in hospitals, focusing on how terminology affects decisions about life-sustaining treatment (LST) and advance care planning.
- It analyzes clinical data from inpatients over a year using a technique called natural language processing to find phrases related to "Ceiling of Treatment" and their connection to patient prognosis.
- Results show that certain phrases closely related to end-of-life care, like "Withdrawal of care," have high mortality rates, emphasizing the need for precise language in discussing LST and end-of-life options.
In this erratum we clarify our previously published paper [Appl. Opt.57, 4008 (2018)APOPAI0003-693510.
View Article and Find Full Text PDFWe report a solar pumped solid state laser using a 20 mm long, 3 mm diameter neodymium-doped yttrium aluminum garnet laser rod. This rod was placed in a liquid cooling chamber using a water-white-emulsion-paint mix. This mix provides cooling for the laser crystal and also doubles as a diffuse light scattering liquid.

View Article and Find Full Text PDFWe describe the characterization of a monolithically integrated photonic device for short pulse generation featuring a mode-locked laser diode, a Mach-Zehnder modulator (MZM), and a semiconductor optical amplifier (SOA). The integrated device is designed for fabrication by a generic foundry scheme with a view to ease of design, testing, and manufacture. Trains of 6.
