Bond dissociation energies (BDEs) and spectroscopic parameters for the ground states of YbO and NoO were calculated at the Brueckner doubles (BD(T)) level and for NoO at the coupled cluster CCSD(T) level based on the closed-shell configurations Yb(4f)O(2p) and No(5f)O(2p). For YbO, the BD(T) BDE (3.93 eV) and vibrational frequency (686.

Design: Two-phase mixed methods: a cross-sectional survey (January 2021-March 2022), with comparator baseline data from April to October 2018 (critical care nurses only), and semistructured interviews.
Participants: Critical care nurses ( = 461) and nurses redeployed to critical care ( = 200) who worked in the United Kingdom National Health Service (primarily Scotland) between January 2021 and March 2022.
Atherosclerotic cardiovascular disease (ASCVD) remains the leading cause of death worldwide. Lowering low-density lipoprotein cholesterol (LDL-C) levels is a primary strategy to reduce ASCVD risk. Although statin therapy remains the initial therapy of choice to reduce LDL-C and ASCVD risk, statin intolerance and suboptimal LDL-C lowering response prompts the need for additional non-statin therapies.

The relationship between Lp(a) and major adverse cardiovascular events (MACE) in the context of high-sensitivity C-reactive protein (hs-CRP) levels remains controversial due to conflicting results from previous studies.
Objectives: This systematic review and meta-analysis aimed to clarify the association between Lp(a) and risk of MACE across different hs-CRP levels in both primary and secondary prevention settings.
Article Synopsis
- - A study using anion photoelectron spectroscopy and computational methods investigated the photodetachment of UF, revealing a vertical detachment energy of 0.63 eV, aligning closely with a theoretical value of 0.61 eV from spinor-based relativistic coupled-cluster methods.
- - The analysis included complex spectral features related to excited electronic states and vibrational movements in UF, facilitated by advanced theoretical techniques like spin-orbit-coupled multireference perturbation theory.
- - The research confirms that UF exhibits strong ionic bonding characteristics and showcases the effectiveness of the spinor CCSD(T) computational approach in analyzing such systems.
