Evaluation of the effect of elective percutaneous intervention to left coronary artery disease on left ventricular functions: an echocardiography and tissue Doppler study

Al-Azhar Assiut Medical Journal, 2018
Background and Aim Coronary artery disease (CAD) is the leading cause of death worldwide. After acute myocardial infarction (AMI), CAD is a serious and common ailment that can influence a patient’s prognosis and quality of life. Aim of the study The aim

Energy Consumption Optimization for Autonomous Vehicles via Positive Control Input Minimization [PDF]

arXiv
Autonomous vehicles (AVs) present a unique opportunity to improve the sustainability of transportation systems by adopting eco-driving strategies that reduce energy consumption and emissions. This paper introduces a novel surrogate model for energy and fuel consumption that minimizes Positive Control Input (PCI).

Fascicular/Purkinje Tissue Colocalized With Scar in Cardiomyopathy Patients Undergoing Ventricular Fibrillation Ablation

Pacing and Clinical Electrophysiology, EarlyView.
ABSTRACT Background Ventricular fibrillation (VF) is a poorly understood arrhythmia that is one of the main mechanisms of sudden cardiac death in patients with structural heart disease (SHD). Fascicular and Purkinje tissue (FPT) has been implicated in VF.

Phase chaos in the anisotropic complex Ginzburg-Landau Equation

, 1998
Of the various interesting solutions found in the two-dimensional complex Ginzburg-Landau equation for anisotropic systems, the phase-chaotic states show particularly novel features. They exist in a broader parameter range than in the isotropic case, and

Self-referencing photothermal common-path interferometry to measure absorption of Si3N4 membranes for laser-light sails [PDF]

arXiv
Laser-light sails are a spacecraft concept wherein lightweight "sails" are propelled to high speeds by lasers with high intensities. The sails must comprise materials with low optical loss, to minimize the risk of laser damage. Stoichiometric silicon nitride (Si$_3$N$_4$) is a candidate material with low loss in the near infrared, but the precise ...

The Dual‐Edged State Paradox: Fighting for Justice When the State is Unreliable

Sociological Inquiry, EarlyView.
Sociological theories of collective resistance offer insights into how communities mobilize against oppression but often overlook the complexities when the state, an entity relied upon for justice, also acts as an agent of betrayal. Based on 8 years of ethnographic research in Palermo (2016–2024), this study examines the relationship between Sicilian ...

Acute alterations in blood lactate in the setting of transient stress induced myocardial ischaemia

Experimental Physiology, EarlyView.
Abstract An elevation in resting venous blood lactate ([La−]b) levels in conditions of myocardial hypoperfusion is associated with adverse prognosis and survival. This investigation aimed to assess changes in venous [La−]b levels induced by dobutamine stress in the presence and absence of myocardial ischaemia and adverse outcomes at 1 year.

A deterministic projector configuration interaction approach for the ground state of quantum many-body systems [PDF]

arXiv, 2016
In this work we propose a novel approach to solve the Schr\"{o}dinger equation which combines projection onto the ground state with a path-filtering truncation scheme. The resulting projector configuration interaction (PCI) approach realizes a deterministic version of the full configuration interaction quantum Monte Carlo (FCIQMC) method [Booth, G. H.;

Enhanced Drug Effect With Cutting Balloon Followed by Drug Coated Balloon in a Rabbit Model

Catheterization and Cardiovascular Interventions, Volume 105, Issue 7, Page 1656-1663, June 1, 2025.
ABSTRACT Background Drug‐coated balloon (DCB) are effective treatment options for patients with coronary artery disease and using of scoring or cutting balloon before the DCB usage were recommended. However, the effectiveness of lesion preparation with cutting balloons (CB) followed by DCB (CB + DCB) has not been evaluated before.
