Effects of mechano-electrical feedback on the onset of alternans: A computational study
(AIP, 2019-06)Cardiac alternans is a heart rhythm instability that is associated with cardiac arrhythmias and may lead to sudden cardiac death. The onset of this instability, which is linked to period-doubling bifurcation and may be a ... -
A Simulation Study of the Role of Mechanical Stretch in Arrhythmogenesis during Cardiac Alternans
(Biophysical Society, 2021-01)The deformation of the heart tissue due to the contraction can modulate the excitation, a phenomenon referred to as mechanoelectrical feedback (MEF), via stretch-activated channels. The effects of MEF on the electrophysiology ... -
Efficiency of semi-implicit alternating direction implicit methods for solving cardiac monodomain model
(Elsevier, 2021-01)It is well known that numerical simulations of the cardiac monodomain model require fine mesh resolution, which increases the computational resources required. In this paper, we construct three operator-splitting alternating ... -
A projection scheme for phase change problems with convection
(Elseiver, 2022-01)Numerical modeling of phase change problems with convection is known to be computationally expensive. The main challenge comes from the coupling between Navier–Stokes and heat energy equations. In this paper, we develop a ... -
Efficiency of parallel anisotropic mesh adaptation for the solution of the bidomain model in cardiac tissue
(Elsevier, 2022-04)Electrocardiology models are nonlinear reaction–diffusion type systems, where the numerical simulation requires extremely fine meshes to accurately compute the heart’s electrical activity. Anisotropic mesh adaptation methods ... -
Numerical modelling of hyperbolic phase change problems: Application to continuous casting
(Elsevier, 2023-03)Heat diffusion processes are generally modeled based on Fourier’s law to estimate how the temperature propagates inside a body. This type of modeling leads to a parabolic partial differential equation, which predicts an ... -
A mixed finite element method for nonlinear radiation–conduction equations in optically thick anisotropic media
(Elsevier, 2023-09)We propose a new mixed finite element formulation for solving radiation–conduction heat transfer in optically thick anisotropic media. At this optical regime, the integro-differential equations for radiative transfer can ... -
Liposomal Encapsulation of Chemotherapeutics Agents Combined with the Use of Ultrasound in Cancer Treatment
(American Scientific Publishers, 2023-07)Ultrasound (US) has numerous uses in the medical field, including imaging, tumor ablation, and lithotripsy; another interesting application of US in cancer therapy is as an external trigger in targeted drug delivery. ... -
Environmental Management Systems in Public Sector
(Edward Elgar, 2023)This chapter focuses on environmental management systems (EMS) in public sector organisations (PSOs). Our objectives are to 1) explain what is an EMS, describe the two main EMS standards (ISO 14001 and EMAS) and how to ... -
Enhancement of the corrosion resistance of mild steel with femtosecond laser- nanostructuring and CrCoNi medium entropy alloy coating
(Elsevier, 2022)In this work, the corrosion resistance of mild steel surface nanostructured with a femtosecond laser and coated with high corrosion resistant CrCoNi (CCN) medium entropy alloy through magnetron sputtering is studied. ... -
Drivers, Challenges and Outcomes of Environmental Management System Implementation in Public Sector Organizations: A Systematic Review of Empirical Evidence
(MDPI, 2023-04-28)Our research objectives were to conduct a systematic literature review of the empirical articles on the drivers, challenges and outcomes of environmental management system (EMS) implementation in public sector organizations ... -
World society and the convergence of consumer values: Buying patterns of eco-certification in the UAE
(Wiley, 2023-04-10)Eco-certifications offer consumers the opportunity to vote with their money for more sustainable methods of production. While consumer-facing eco-labels are mostly recognized and consumed in western countries little is ... -
Tradition and its significance within Islam and the Abrahamic faiths
(USIM Press (Universiti Sains Islam Malaysia), 2022-05-22)The present article looks into the position and significance of tradition within Islam and the Abrahamic Faiths. Tradition in its very theological sense is generally believed to have divine authority albeit not as part of ... -
Insights into rechargeable Zn-air batteries for future advancements in energy storing technology
(Elsevier, 2023-02-27)Owing to its high theoretical specific energy density, low cost, abundance and environmental friendliness, the rechargeable Zn-Air batteries (ZAB) are becoming the most prevalent candidate as energy storage devices for ... -
Pushing against a future dark side for community development: An editorial call to action
(Taylor & Francis, 2023)Community Development as a journal has undergone streamlining, yet much work remains to improve the journal’s relations with its many stakeholders around the world and within the field of community development. Community ... -
It’s Not You, It’s Us: Relationship-Based Factors That Predict Infidelity
(Oxford University Press, 2022-07-12)Infidelity is often defined as perceived as a violation of relationship exclusivity rules, and many view infidelities as immoral. Thus, one can imagine the importance of understanding why up to a fifth of research samples ... -
Modeling of the In Vitro Release Kinetics of Sonosensitive Targeted Liposomes
(MDPI, 2022-12-05)Targeted liposomes triggered by ultrasound are a promising drug delivery system as they potentially improve the clinical outcomes of chemotherapy while reducing associated side effects. In this work, a comprehensive model ... -
Graph of Linear Transformations Over R
(Springer, 2022-12-01)In this paper, we study a connection between graph theory and linear transformations of finite dimensional vector spaces over R (the set of all real numbers). Let Rm, Rn be finite vector spaces over R, and let L be the set ... -
Maximum principles and overdetermined problems for Hessian equations
(ISTE Group, 2021)In this article we investigate some Hessian type equations. Our main aim is to derive new maximum principles for some suitable P-functions, in the sense of L.E. Payne, that is for some appropriate functional combinations ... -
Renormalization functions of the tricritical O(N)-symmetric Φ⁶ model beyond the next-to-leading order in 1/N
