The divide expand consolidate scheme for unrestricted second order Møller-Plesset perturbation theory ground state energies.

The linear scaling divide-expand-consolidate (DEC) framework is expanded to include unrestricted Hartree-Fock references. By partitioning the orbital space and employing local molecular orbitals, the full molecular calculation can be performed as independent calculations on individual fragments, making the method well-suited for massively parallel implementations. This approach also incorporates error control through the fragment optimization threshold (FOT), which maintains precision and consistency throughout the calculations.

Cognitive component of auditory attention to natural speech events.

The recent progress in auditory attention decoding (AAD) methods is based on algorithms that find a relation between the audio envelope and the neurophysiological response. The most popular approach is based on the reconstruction of the audio envelope from electroencephalogram (EEG) signals. These methods are primarily based on the exogenous response driven by the physical characteristics of the stimuli.

Cluster perturbation theory. XI. Excitation-energy series using a variational excitation-energy function.

Traditionally, excitation energies in coupled-cluster (CC) theory have been calculated by solving the CC Jacobian eigenvalue equation. However, based on our recent work [Jørgensen et al., Sci.

Anaesthesia teams´ perception of mental wellbeing, the psychosocial work environment and patient safety culture.

Background: Mental health issues among healthcare professionals (HCPs) are rising, impacting individual wellbeing, healthcare systems, and patient safety. This exploratory study aimed to analyse the association between anaesthesia teams' perception of their mental wellbeing, psychosocial work environment, and patient safety culture in a university hospital's anaesthesiology department. Second, to identify types of stressors and strategies to overcome them.

Role of Vitamin B in Healthy Ageing and Disease.

B vitamin complex consist of vitamins B1, B2, B5, B6, B9, B12 and is pivotal for overall health, influencing vital functions such as, energy metabolism, DNA maintenance, and healthy immune system. Inadequate B vitamin levels are associated with various health issues, including neurocognitive problems, immune imbalances, and inflammation. In ageing individuals, deficiencies in B vitamins increase the risk of cardiovascular ailments, stroke, cognitive disorders, neurodegeneration, mental health issues, and methylation-related disorders.
