In this paper we study the pointwise convergence problem along a tangential curve for fractional Schrodinger equations in one spatial dimension and estimate capacitary of divergence set. We extend prior by Lee first author classical equation, which itself contains result due to Lee, Vargas author, equation. The proof is based on decomposition argument without time localization, has recently bee...

The aim of this paper is to apply the Said Ball curve (SBC) find approximate solution fractional differential-algebraic equations (FDAEs). This method can be applied solve various types order differential equations. Convergence theorem proved. Some examples are presented show efficiency and accuracy method. Based on obtained results, SBC more accurate than Bezier

Background: Invasive Fractional Flow Reserve Obstructive coronary artery disease (CAD) produces symptoms and increases the risk of adverse cardiac outcomes. However, determining whether a particular coronary stenosis is responsible for causing myocardial ischemia can be challenging, even with invasive coronary angiography (ICA). To help guide decisions in the cardiac catheterization laboratory,...

Fractional flow reserve, as determined with a pressure-wire, was validated in the assessment of the functional severity of intermediate lesions in a population with stable ischemic cardiopathy. The value of pressure-wire analysis in acute coronary syndrome is unknown. We report two patients with acute coronary syndrome, in which the therapeutic approach was guided by the fractional flow reserve...

This study aimed to evaluate the feasibility and utility of using motorized pullback of the pressure guidewire to provide a graphic assessment and prediction of the benefits of coronary intervention. Fractional flow reserve (FFR) measurements were performed with motorized pullback imaging in 20 patients who underwent successful percutaneous coronary intervention (PCI) of the left anterior desce...

In this paper, a Modular Fractional Chaotic Sine Map (MFC-SM) has been introduced to achieve high Lyapunov exponent values and completely chaotic behavior of the bifurcation diagram for level security. The proposed MFC-SM is compared with conventional non it an excellent analysis. addition, randomness test results indicate that shows better performance satisfy all tests. Due properties good ran...

BACKGROUND Small drifts in intracoronary pressure measurements (±2 mm Hg) can affect stenosis categorization using pressure indices. This has not previously been assessed for fractional flow reserve (FFR), instantaneous wave-free ratio (iFR), and whole-cycle distal pressure/proximal pressure (Pd/Pa) indices. METHODS AND RESULTS Four hundred forty-seven stenoses were assessed with FFR, iFR, an...

Exact expressions of velocity, temperature and mass concentration have been calculated for free convective flow of fractional MHD viscous fluid over an oscillating plate. Expressions of velocity have been obtained both for sine and cosine oscillations of plate. Corresponding fractional differential equations have been solved by using Laplace transform and inverse Laplace transform. The expressi...
