The Nodal Boundary Condition Method : Wave Functions and Transition Probabilities for Atoms with Two Valence Electrons [PDF]

, 1963
A method is presented for computing valence atomic wave functions and transition probabilities. This method, called the "nodal boundary condition method", is a modified self-consistent-field approach to eliminate the need for calculating wave functions ...

Fluid Biomarkers of Disease Burden and Cognitive Dysfunction in Progressive Supranuclear Palsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Identifying objective biomarkers for progressive supranuclear palsy (PSP) is crucial to improving diagnosis and establishing clinical trial and treatment endpoints. This study evaluated fluid biomarkers in PSP versus controls and their associations with regional 18F‐PI‐2620 tau‐PET, clinical, and cognitive outcomes.

Stability of Geometrically Recurrent Time-inhomogeneous Markov Chains

Austrian Journal of Statistics
This paper is devoted to establishing upper bounds for a difference of n-step transition probabilities for two time-inhomogeneous Markov chains with values in a locally compact space when their one-step transition probabilities are close.

Colombian economic growth under Markov switching regimes with endogenous transition probabilities [PDF]

In this paper, we modelled the Colombian long run per capita economic growth (1925-2005) using a Markov switching regime model with both fixed (FTP) and time-varying transition probabilities (TVTP) to explain regime changes in the economic growth.

Baseline Regional Cholinergic Denervation Predicts Cognitive Trajectories in Moderate Parkinson Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cognitive decline is a disabling and variable feature of Parkinson disease (PD). While cholinergic system degeneration is linked to cognitive impairments in PD, most prior research reported cross‐sectional associations. We aimed to fill this gap by investigating whether baseline regional cerebral vesicular acetylcholine transporter ...

Improved H2 controller design for Markov jump linear system with general transition probabilities

, 2012
This paper concentrates on the problem of designing H2 state-feedback controllers for continuous-time Markovian jump linear systems (MJLSs) with more general transition rates.

A Prospective Study of Individuals at Risk of Multiple Sclerosis Informs the Design of Primary Prevention Studies

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective In multiple sclerosis, the optimal time for deploying a therapeutic intervention is before the central nervous system is damaged; given the success of trials treating the earliest stage of MS, the radiologically isolated syndrome, developing primary prevention strategies is an important next challenge.

Modelling Low Pay Transition Probabilities, Accounting for Panel Attrition, Non-Response, and Initial Conditions [PDF]

We model annual low pay transition probabilities taking account of three potentially endogenous selections: two sample drop-out mechanisms (panel attrition, non-employment) and ‘initial conditions’ (base-year low pay status).
