Atherosclerosis is a major underlying cause of cardiovascular conditions. In order to understand the biomechanics involved in the generation and rupture of atherosclerotic plaques, numerical analysis methods have been ...

• Aerodynamics in different epiglottis states were estimated by virtual surgery.
• Changes in the epiglottis angle have an important effect on the flow field.
• Aerodynamic analysis may help to predict the airway surgical outcomes.

A large proportion of infants with vallecular cyst (VC) have coexisting laryngomalacia (LM). Feeding difficulties, regurgitation, occasional cough, and sleep-disordered breathing are the common symptoms in moderate to ...

• This case-control hemodynamic study suggested that.
• The obvious helical flow was found in healthy aortic arches.
• The loss of helical flow and increased NtransWSS were observed in pre-TBAD subjects, which might result in abnormal ...

The occurrence of acute type B aortic dissection (TBAD) remained unclear. This study aimed to investigate the association between flow features and hemodynamic parameters in aortas that demonstrated the risk of TBAD ...

To explore the role of hemodynamic factors in the occurrence of superior mesenteric artery (SMA) dissection (SMAD) using a fluid–structure interaction (FSI) simulation method, and to identify histopathologic ...

• Aneurysmal haemodynamics of 19 patients were quantified by CFD simulations incorporating physiologically real boundary conditions measured in vivo.
• Statistically significant difference was found between simulations using generic and ...

Initiation, growth, and rupture of intracranial aneurysms are believed to be closely related to their local haemodynamic environment. While haemodynamics can be characterised by use of computational fluid dynamics (CFD), ...

• Wall Shear Stress (WSS) is associated with coronary artery disease risk.
• ...

Haemodynamic metrics, such as blood flow induced shear stresses at the inner vessel lumen, are associated with the development and progression of coronary artery disease. Understanding these metrics ...

Discrete subaortic stenosis (DSS) is an obstructive cardiac disease caused by a membranous lesion in the left ventricular (LV) outflow tract (LVOT). Although its etiology is unknown, the higher prevalence of DSS in ...

• We assess the impact of aortoseptal angle (AoSA) alterations on hemodynamic stress.

Superficial femoral arteries (SFAs) treated with self-expanding stents are widely affected by in-stent restenosis (ISR), especially in case of long lesions and multiple overlapping devices. The altered ...

This paper presents a novel energy-efficient all-optical switch architecture for high-performance computing (HPC) systems and datacenter networks (DCNs), that employs the arrayed waveguide grating router (AWGR) and wavelength selective switches (WSSs). ...

We evaluated the influences of the myocardial bridges on the plaque localization in the coronary arteries.We investigated the prediction of "the best" position for plaque progression using WSS, OSI and residence time.A good correlation between positions ...

One approach for real-time scheduling on multicore platforms involves task partitioning, which statically assigns tasks to cores, enabling subsequent core-local scheduling. No past partitioning schemes explicitly consider cache effects. We present a ...

Due to its distributed and open nature, Web Services give rise to new security challenges. This technology is susceptible to Cross-site Scripting (XSS) attack, which takes advantage of existing vulnerabilities. The proposed approach makes use of two ...

Most traditional objective indices don't distinguish between a real sound and a perceived sound, and therefore, these indices have limitations in regard to the evaluation of the real effect of an algorithm under investigation on the auditory perception ...

In this study the biomechanical characteristics of a realistic carotid artery [3] are studied numerically using different inlet velocity profiles. Several experimental data measured [32] at the common carotid artery are used as inlet boundary ...

Two-degree ROADM can be upgraded to next generation dynamically reconfigurable multi-degree OADM using an Nx1 Wavelength Select Switch (WSS). WSS enables routing of selected wavelengths from a (local) degree to N (remote) degrees. In a typical multi-...
