Household food insecurity and cooking energy access in Nigeria: A panel data approach

open access: yesEnergy Nexus, 2023
Access to sources of cooking energy has potential impacts on food security, however, there is a paucity of information and empirical evidence on their linkages.

Multicollinearity and Linear Predictor Link Function Problems in Regression Modelling of Longitudinal Data

open access: yesMathematics, 2023
In the longitudinal data analysis we integrate flexible linear predictor link function and high-correlated predictor variables. Our approach uses B-splines for non-parametric part in the linear predictor component.

On global regularity of 2D generalized magnetohydrodynamic equations [PDF]

open access: yes, 2013
In this article we study the global regularity of 2D generalized magnetohydrodynamic equations (2D GMHD), in which the dissipation terms are –ν(–Δ)αu and –κ(–Δ)βb. We show that smooth solutions are global in the following three cases: α≥1/2, β≥1; 0≤α≤1/2,

Factors associated with mortality from tuberculosis in Iran: an application of a generalized estimating equation-based zero-inflated negative binomial model to national registry data [PDF]

open access: yesEpidemiology and Health, 2019
OBJECTIVES Tuberculosis (TB) is a global public health problem that causes morbidity and mortality in millions of people per year. The purpose of this study was to examine the relationship of potential risk factors with TB mortality in Iran. METHODS This

Risk factors for diarrhea in a cohort of dairy heifer calves reared in individual outdoor hutches in Piraí, Rio de Janeiro, Brazil

open access: yesSemina: Ciências Agrárias, 2016
This study aimed to evaluate the association between diarrhea and risk factors potentially related to diarrhea incidence, such as Cryptosporidium, Giardia, Eimeria and nematode infection, animal age, failure to transfer passive immunity, type of ...

Pathway analysis of rare variants for the clustered phenotypes by using hierarchical structured components analysis

open access: yesBMC Medical Genomics, 2019
Backgrounds Recent large-scale genetic studies often involve clustered phenotypes such as repeated measurements. Compared to a series of univariate analyses of single phenotypes, an analysis of clustered phenotypes can be useful for substantially ...
