Interpretability and Representability of Commutative Algebra, Algebraic Topology, and Topological Spectral Theory for Real‐World Data

Advanced Intelligent Discovery, EarlyView.
This article investigates how persistent homology, persistent Laplacians, and persistent commutative algebra reveal complementary geometric, topological, and algebraic invariants or signatures of real‐world data. By analyzing shapes, synthetic complexes, fullerenes, and biomolecules, the article shows how these mathematical frameworks enhance ...

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

Revista 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.

Giving and receiving help in three contexts as predictors of alcohol outcomes in a longitudinal study of sober living house residents

American Journal of Community Psychology, EarlyView.
Abstract Although peer support is central to the social model approach emphasized in sober living houses (SLHs), no longitudinal studies have examined helping among SLH residents. This longitudinal study examined benefits of helping in three contexts among SLH residents. Data were from 205 participants entering 28 SLHs across 2021–2023. Interviews were

Analysis of distributional variation through multi-scale Beta-Binomial modeling

, 2016
Many statistical analyses involve the comparison of multiple data sets collected under different conditions in order to identify the difference in the underlying distributions. A common challenge in multi-sample comparison is the presence of various confounders, or extraneous causes other than the conditions of interest that also contribute to the ...

Bayesian Estimation of the Shape Parameters of Mcdonald Generalized Beta-Binomial Distribution

OALib, 2020
The paper explores and establishes a unique Bayesian framework for estimating three shape parameters of the McDonald generalized beta-binomial distribution. The mixture distribution is used in modelling overdispersed binomial data. Foundations of the framework have been enriched by knowledge of Bayesian statistics and Markov Chain Monte Carlo methods ...

Genetic Contribution to Asthma Informs Acute Chest Syndrome Pathophysiology and Risk Stratification

American Journal of Hematology, EarlyView.
ABSTRACT Acute chest syndrome (ACS) is a severe complication of sickle cell disease (SCD) occurring in ~50% of patients, some presenting frequent episodes. We lack tools to identify patients at high risk of ACS occurrence or frequent episodes. Epidemiological studies have found an association between asthma and ACS, but whether this link is causal is ...

The Longitudinal Effect of APOL1 Risk Alleles on Sickle Cell Anemia‐Associated Kidney Function

American Journal of Hematology, EarlyView.
ABSTRACT Progressive kidney injury is a major cause of morbidity and mortality in sickle cell anemia (SCA). The high risk APOL1 G1/G2 variants contribute to the development of kidney disease in individuals of African ancestry, including those with SCA.

Heterogeneous model for superdiffusive movement of dense core vesicles in C. elegans

Scientific Reports
Transport of dense core vesicles (DCVs) in neurons is crucial for distributing molecules like neuropeptides and growth factors. We studied the experimental trajectories of dynein-driven directed movement of DCVs in the ALA neuron in C.

Immunologic Profiling Suggests an Association Between Treg Cell Dysfunction and Pain in Knee Osteoarthritis

Arthritis &Rheumatology, EarlyView.
Objective Pain is the hallmark symptom of osteoarthritis (OA), and its biologic drivers remain poorly understood. Although the role of innate immunity in OA has been extensively studied, the involvement of adaptive immunity, in particular Treg cells, is not well understood.
