Optimal cost tuning of frustration: Achieving desired states in the Kuramoto-Sakaguchi model [PDF]
Phys. Rev. E 103, 012216 (2021), 2021 There are numerous examples of studied real-world systems that can be described as dynamical systems characterized by individual phases and coupled in a network like structure. Within the framework of oscillatory models, much attention has been devoted to the Kuramoto model, which considers a collection of oscillators interacting through a sinus ...

SINUS NODE DYSFUNCTION IN CHILDREN [PDF]
Pediatric Research, 1977 Over a three year period, 30 pedlatric patients (pts) with electrocardiographic evidence of sinus node dysfunction (SND) were identified. Their ages ranged from 3 days to 21 years. Twenty-two pts had significant heart disease. In 13, the onset of SND followed corrective cardiac surgery, and of these, 8 were operations for atrial septal defect and ...

Effects of atrial fibrillation on the arterial fluid dynamics: a modelling perspective [PDF]
Meccanica, published online June 2018, 2018 Atrial fibrillation (AF) is the most common form of arrhythmia with accelerated and irregular heart rate (HR), leading to both heart failure and stroke and being responsible for an increase in cardiovascular morbidity and mortality. In spite of its importance, the direct effects of AF on the arterial hemodynamic patterns are not completely known to ...

Pheochromocytoma and sinus node dysfunction [PDF]
Baylor University Medical Center Proceedings, 2019 Pheochromocytomas are rare catecholamine-producing neuroendocrine tumors that can lead to detrimental outcomes; if identified and treated, they are associated with a good prognosis. The clinical presentation can vary greatly but is classically associated with tachycardia, headaches, and hypertension.
