Heart-like fair queuing algorithms (HLFQA) [PDF]
, 2006 We propose a new family of fair, work conserving traffic scheduling mechanisms that imitate the behavior of the human heart in the cardiovascular system.

Left ventricular diastolic dysfunction: Early diastolic relaxation and late diastolic compliance
Journal of the American College of Cardiology, 1989 The fundamental importance of cardiac filling in regulating performance of the heart was recognized by Starling (I) early in this century. Development of comprehensive ventricular function curves by Sarnoff and others (la,2) beginning in the 1950s focused attention on the role of ventricular compliance in influencing cardiac pump performance by ...

Current perspectives in diastolic dysfunction and diastolic heart failure [PDF]
Heart, 2006 Diastolic heart failure (HF) has emerged over the last two decades as a separate clinical entity. Approximately half of the patients presenting with symptoms of congestive HF exhibit a near normal left ventricular (LV) systolic function at rest, which is thought to be caused by a predominant abnormality in diastolic function. It is generally considered

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Cardiac motion may degrade dose distribution during stereotactic arrhythmia radioablation using the CyberKnife system, a robotic radiosurgery system. This study evaluated the dose distribution changes using a self‐made cardiac dynamic platform that mimics cardiac motion. Methods The cardiac dynamic platform was operated with amplitudes

Impaired coronary blood flow at higher heart rates during atrial fibrillation: investigation via multiscale modelling [PDF]
, 2019 Background. Different mechanisms have been proposed to relate atrial fibrillation (AF) and coronary flow impairment, even in absence of relevant coronary artery disease (CAD). However, the underlying hemodynamics remains unclear.

A semiparametric regression model for paired longitudinal outcomes with application in childhood blood pressure development [PDF]
Annals of Applied Statistics 2012, Vol. 6, No. 4, 1861-1882, 2013 This research examines the simultaneous influences of height and weight on longitudinally measured systolic and diastolic blood pressure in children. Previous studies have shown that both height and weight are positively associated with blood pressure.

Cerebral autoregulation in patients with acute lacunar infarction: a reliable predictor of outcome
Annals of Clinical and Translational Neurology, EarlyView.Abstract Objective To further investigate the association between dynamic cerebral autoregulation (dCA) and the outcomes in patients with acute lacunar infarction. Methods Patients were prospectively and consecutively enrolled at The First Hospital of Jilin University between 2016 and 2023. dCA was monitored at 1–3 and 7–10 days after the stroke.

Diastolic and isoperimetric inequalities on surfaces [PDF]
Annales scientifiques de l'\'Ecole Normale Sup\'erieure, S\'erie
4, Tome 43 (2010) no. 4, pp. 579-605We prove a universal inequality between the diastole, defined using a minimax process on the one-cycle space, and the area of closed Riemannian surfaces. Roughly speaking, we show that any closed Riemannian surface can be swept out by a family of multi-loops whose lengths are bounded in terms of the area of the surface. This diastolic inequality, which

Arthritis Care &Research, EarlyView.Objective Metabolic syndrome (MetS) is a known comorbidity of psoriatic arthritis (PsA) and is associated with PsA disease activity. We aimed to explore the association between MetS and radiographic features (peripheral and axial) in PsA. Methods We included patients with PsA followed at our prospective observational cohort for the period between 1978 ...
