Circulating Exosomes Drive Persistent Neuronal Dysfunction in Post‐Herpetic Neuralgia Patients

open access: yesAnnals of Neurology, EarlyView.
Proposed model of exosome‐mediated neuronal dysfunction in post‐herpetic neuralgia (PHN). (1) Circulating, non‐pathogenic exosomes maintain homeostatic processes in healthy skin, where sensory nerve fibers innervate the epidermis and dermis. (2) During acute zoster, reactivating varicella zoster virus (VZV) travels down neurites to the skin causing ...

Understanding the Pattern of Cognitive Decline in GBA1‐Related Parkinson's Disease: An Exploratory Longitudinal Multi‐Cohort Study

open access: yesAnnals of Neurology, EarlyView.
Objective People with Parkinson's disease (PD) who carry a pathogenic GBA1 variant (PDGBA1) are at higher risk of cognitive impairment than those without the variant (PDGBA1_wildtype). To date, little is known about the pattern and evolution of cognitive decline in PDGBA1. This multicenter study characterized the cognitive profile of PDGBA, focusing on

Beta Regression in R [PDF]

open access: yes
The class of beta regression models is commonly used by practitioners to model variables that assume values in the standard unit interval (0, 1). It is based on the assumption that the dependent variable is beta-distributed and that its mean is related ...

Estudio de homogeneidad de la dispersión en diseño a una vía de clasificación para datos de proporciones y conteos Study of Homogeneity of the Dispersion in one way Classification Models with Proportions and Counts Data

open access: yesRevista Colombiana de Estadística, 2009
En el modelamiento de datos donde se evidencia la presencia de sobredispersión, usualmente se asume que para todos los efectos de tratamiento el parámetro de sobredispersión es común.

Generalized Binomial Trees [PDF]

open access: yes
We consider the problem of consistently pricing new options given the prices of related options on the same stock. The Black-Scholes formula and standard binomial trees can only accommodate one related European option which then effectively specifies the

STUDY OF HOMOGENEITY OF THE DISPERSION IN ONE WAY CLASSIFICATION MODELS WITH PROPORTIONS AND COUNTS DATA ESTUDIO DE HOMOGENEIDAD DE LA DISPERSIÓN EN DISEÑO A UNA VÍA DE CLASIFICACIÓN PARA DATOS DE PROPORCIONES Y CONTEOS

open access: yesRevista Colombiana de Estadística, 2009
When analyzing data in the presence of over dispersion, the usual practice is to assume a common dispersion parameter to all observations. However, there are situations where the assumption of homogeneity of the dispersion parameter does not hold.

Alternating Inverse-Binomial Double Series

open access: yesMathematics
We study inverse-binomial double series involving ordinary and alternating harmonic numbers. Using iterated integrals associated with admissible 3-posets, we establish twenty-four explicit evaluations in terms of multiple zeta values and alternating ...
