Abstract: We extend the theoretical prediction for the width difference ΔΓ_{q} in the mixing of neutral B mesons in the Standard Model to next-to-next-to-leading order in α_{s}. To this aim, we calculate three-loop diagrams with two… read more here.

DOI: 10.3389/fmed.2023.1109681
Abstract: Background This meta-analysis aimed at assessing the diagnostic accuracy of ultrasound-measured laryngeal air column width difference (ACWD) in predicting post-extubation stridor (PES) in intubated adult patients. Methods We searched the Medline, Cochrane Library, EMBASE, and… read more here.
