Joint frailty model for recurrent events and a terminal event in the presence of cure fraction

Epidemiology, Biostatistics and Public Health, 2023
The observations of repeated or recurrent events occur in many longitudinal studies. Furthermore, sometimes there may exist a terminal event such as death, which is strongly correlated with recurrent events.

Feedback-Linearization-Based Fuel-Cell Adaptive-Control Paradigm in a Microgrid Using a Wavelet-Entrenched NeuroFuzzy Framework

Energies, 2021
The article portrays an adaptive control paradigm for the swift response of a solid-oxide fuel cell (SOFC) in a grid-connected microgrid. The control scheme is based on an adaptive feedback-linearization-embedded fully recurrent NeuroFuzzy Laguerre ...

Recurrent Sequences and Affine Functional Equations

Journal of Number Theory, 1996
An arithmetic function \(f:\mathbb{N}\to\mathbb{C}\) is called recurrent if there are complex constants \(a_0,\dots,a_{k-1}\), \(a_0\neq 0\), such that \[ f(n+k)+a_{k-1}f(n+k-1)+\dots+a_1f(n+1)+a_0f(n)=0\tag{1} \] holds for all natural numbers \(n\). If (1) is satisfied for large values of \(n\) only then \(f\) is called ultimately recurrent.

Decreased Human Leukocyte Antigen-G Expression by miR-133a Contributes to Impairment of Proinvasion and Proangiogenesis Functions of Decidual NK Cells

Frontiers in Immunology, 2017
Human leukocyte antigen (HLA)-G plays a crucial role in conferring fetal–maternal tolerance and ensuring a successful pregnancy. CD56bright natural killer (NK) cells accumulate at the maternal decidua in large numbers during pregnancy and are found in ...
