CSF Monoamine Metabolites and Cognitive Trajectory in Early Parkinson's Disease
ABSTRACT Background Imaging and postmortem studies indicate that abnormalities in monoaminergic neurotransmission contribute to cognitive impairment in Parkinson's disease (PD). However, it remains uncertain if cerebrospinal fluid (CSF) monoamine metabolites can serve as biomarkers of cognitive decline in early PD.

Elevated Connectivity During Language Processing Is Associated With Cognitive Performance in SeLECTS
ABSTRACT Objective Self‐Limited Epilepsy with Centrotemporal Spikes (SeLECTS) is associated with language impairments despite seizures originating in the motor cortex, suggesting aberrant cross‐network interactions. Here we tested whether functional connectivity in SeLECTS during language tasks predicts language performance.

ABSTRACT Objective Intravenous thrombolysis (IVT) before thrombectomy for ischemic stroke may alter clot structure and procedural performance. We investigated how IVT relates to thrombectomy metrics across stroke etiologies. Methods We performed a time‐to‐event analysis of consecutive patients with anterior circulation large vessel occlusion (acLVO ...

Relative Aging of Distributions
Probability in the Engineering and Informational Sciences, 1998We consider the reliability of one random variable relative to another, when the variables are continuous and take values in an interval [a, b). We give definitions and characterizations for the exponential property and the standard aging properties IFR, IFRA, and NBU.

On the Interpretation of Age Distributions
Journal of the American Statistical Association, 1967Abstract Given a national census and a life table we may wish to infer the birth rate and hence the rate of natural increase. The model for making the inference here presented specifies the form of the preceding births and an intuitively selected life table if death statistics are not available.

Game of Ages in a Distributed Network
IEEE Journal on Selected Areas in Communications, 2021We consider a distributed IoT network, where each node wants to minimize its own age of information and there is a cost to make any transmission. A collision model is considered, where any transmission is successful from a node to a common monitor if no other node transmits in the same slot.

The Age Distribution of Poliomyelitis in Massachusetts
New England Journal of Medicine, 1948DATA concerning the incidence of poliomyelitis in Massachusetts have been collected by the Department of Public Health since 1907. This material had been studied statistically by Forsbeck and Luther1 in 1930, and it was thought that a review of these older records, combined with the data accumulated during the past fifteen years would yield additional ...
