Association of SIRT1 (rs7069102) Gene polymorphism with premature myocardial infarction in young Egyptian patients
Autor: Ali Mohamad Altaher, Amera Morad Foad, Wael Youssef, Ahmed Elsharawy Ahmed
Publikováno v: Egyptian Journal of Medical Human Genetics, Vol 25, Iss 1, Pp 1-10 (2024)
Abstract Background Premature myocardial infarction (PMI) is one of the most pressing global issues in modern cardiology. Recently, the incidence of PMI has gradually increased. Researches found that genetics is a major contributor in its development

Polynomial stability of a transmission problem involving Timoshenko systems with fractional Kelvin–Voigt damping
Autor: Aissa A Guesmia, Zeinab Mohamad Ali, Ali Wehbe, Wael Youssef
Publikováno v: Preprint, submitted to Operational Research-An International Journal (ORIJ)
International audience; In this work, we study the stability of a one-dimensional Timoshenko system with localized internal fractional kelvin-Voigt damping in a bounded domain. First, we reformulate the system into an augmented model and using a gene

Discrete observability of the Bresse system
Autor: Toufic El Arwadi, Wael Youssef, Ali Wehbe
Publikováno v: Mathematics and Mechanics of Solids. 28:1170-1189
In this work, a recent type of observability inequality for the Bresse system in one-dimensional–bounded domain is investigated. First, a finite element implicit Euler scheme is studied. More precisely, a priori error estimate is established which

Analysis of a contact problem for a viscoelastic Bresse system
Autor: Toufic El Arwadi, José R. Fernández, M. I. M. Copetti, Wael Youssef, Maria Grazia Naso
Publikováno v: ESAIM: Mathematical Modelling and Numerical Analysis. 55:887-911
In this paper, we consider a contact problem between a viscoelastic Bresse beam and a deformable obstacle. The well-known normal compliance contact condition is used to model the contact. The existence of a unique solution to the continuous problem i

On the Stabilization of the Bresse Beam with Kelvin–Voigt Damping
Autor: Toufic El Arwadi, Wael Youssef
Publikováno v: Applied Mathematics & Optimization. 83:1831-1857
The aim of this paper is to study the theoretical and numerical stability of the Bresse system in one-dimensional bounded domain with viscoelastic Kelvin–Voigt damping. We first showed the well posedness of the system. Then stability is obtained by

Age-Dependent Differential Expression of Apoptotic Markers in Rat Oral Mucosa
Autor: Wael Youssef Elias
Publikováno v: Asian Pacific Journal of Cancer Prevention : APJCP
Objective: This study tests the hypothesis that gingival tissue produces age-dependent activation of apoptotic markers. Methods: To address the hypothesis, a prospective experimental study was conducted on 20 adult male albino rats, which were divide
