Katharina Boguslawski, Pawel Tecmer
Wave functions restricted to electron-pair states are promising models to describe static/nondynamic electron correlation effects encountered, for instance, in bond-dissociation processes and transition-metal and actinide chemistry. To reach spectroscopic accuracy, however, the missing dynamic electron correlation effects that cannot be described by electron-pair states need to be included a posteriori. In this article, we extend the previously presented perturbation theory models with an Antisymmetric Product of 1-reference orbital Geminal (AP1roG) reference function that allow us to describe both static/nondynamic and dynamic electron correlation effects...

BACKGROUND: The present study was designed to assess the underlying mechanism of decline in effort capacity seen with aging. METHODS: We analyzed 250 healthy senior patients (≥65 years) with an ejection fraction ≥60% who underwent a stress echocardiogram test. The seniors (aged 65-94) were divided into 3 equal age groups (groups 1, 2, and 3), and their echo characteristics at rest and peak exercise (measured and calculated) were compared. RESULTS: Diastolic function at rest declined significantly (E lateral, E septal, E/E', A) with age, while other rest parameters were similar...

INTRODUCTION: Complex skull base approaches are frequently used to treat intracranial vertebral artery (VA) and proximal posterior inferior cerebellar artery (PICA) aneurysms. These complex procedures are associated with higher risk of neurovascular injury. Hence, a less invasive surgical approach is needed to improve treatment's efficacy and safety. MATERIAL AND METHODS: A retrospective analysis was conducted on clinical and radiological data from surgeries where simple lateral suboccipital and "lateral enough" approaches were used to clip VA aneurysms in the Department of Neurosurgery at Helsinki University Central Hospital from 2000 - 2009...

The purpose of this research is to examine the relation between operating efficiency and the quality of care of senior care facilities. We designed a data envelopment analysis, combining epsilon-based measure and metafrontier efficiency analyses to estimate the operating efficiency for senior care facilities, followed by an iterative seemingly unrelated regression to evaluate the relation between the quality of care and operating efficiency. In the empirical studies, Taiwan census data was utilized and findings include the following: Despite the greater operating scale of the general type of senior care facilities, their average metafrontier technical efficiency is inferior to that of nursing homes...
