Background: The role of the ratio between the arterial partial pressure of oxygen and the inspired fraction of oxygen (PaO/FiO ratio) during the change in position is not fully established.

Methods: This retrospective, single-center cohort study included 98 patients with severe COVID-19 pneumonia.

Objective: This study aimed to evaluate the predictive value of the PaO/FiO ratio for survival in patients with severe COVID-19 pneumonia between changing from supine to prone positions and .

Considerable focus on tin-based perovskites lies on substitution to leadhalide perovskites for the fabrication of eco-friendly optoelectronic devices. The major concern related to tin-based perovskite devices are mainly the stability and the efficiency. However, thinking on the final commercialization scope, other considerations such as precursor stability and cost are major factors to carry about.

The development of random lasing (RL) with predictable and controlled properties is an important step to make these cheap optical sources stable and reliable. However, the design of tailored RL characteristics (emission energy, threshold, number of modes) is only obtained with complex photonic structures, while the simplest optical configurations able to tune the RL are still a challenge. This work demonstrates the tuning of the RL characteristics in spin-coated and inkjet-printed tin-based perovskites integrated into a vertical cavity with low quality factor.
