Background: Markers of central haemodynamics have in recent years emerged as promising predictors of cardiovascular disease (CVD). Central haemodynamics are affected early in the development of vascular aging and affect organs directly attached to large arteries. Carotid-Femoral pulse wave velocity (c-f...

Background: Cardiovascular disease is a leading cause of disease progression and death in multiple sclerosis (MS). Obesity has a negative impact on vascular structure and function, but whether this contributes to worse vascular function similarly in individuals with MS and controls is unknown. Aim:...

Recently, several digital watermarking techniques have been proposed for protecting the copyright of moving image files by hiding data in the frequency domain. In the present study, we applied our method for authenticating a moving image, which uses a discrete wavelet transform for a static image and...

In the previous works, several types of the Self-Repairing Control Systems (SRCS) have been developed against unknown sensor failures. The SRCS can automatically detect failures, and replace failed sensors with healthy backups so as to maintain the system stability. This paper presents a new SRCS, whose...

In this paper, we aim to provide a better assembly method for a snap joints assembly task. We create a 3D cellphone model and use ADAMS simulation environment to analyze the relative motion between screen and backer part. We focus on two points in this research. 1) Two kinds of relative motion between...

Coexisting conditions are relatively common in children with cancer, however, there is a paucity of information on the prevalence of coexisting conditions in children with cancer in South Africa. This cross-sectional study aimed at investigating the common coexisting conditions occurring in children...

We identify a solvable dynamical system — interpretable to some extent as a many-body problem — and point out that — for an appropriate assignment of its parameters — it is entirely isochronous, namely all its nonsingular solutions are completely periodic (i.e., periodic in all degrees of freedom) with...

Objective: The aim of this study is to investigate the relationship of Metabolic Syndrome (MetS) and its components with arterial stiffness in general population without cardiovascular diseases. Design and method: Cross-sectional study of general population without cardiovascular diseases. There were...

Objective: Systemic lupus erythematosus (SLE) is a chronic inflammatory disease associated with vascular derangement [1]. Leptin and adiponectin are adipokines with immunomodulatory and vascular functions [2]. We studied the association between arterial stiffness and plasma leptin and adiponectin levels...

Greater very short- to mid-term blood pressure variability (BPV) has been associated with an increased CVD risk, especially stroke. However, this link remains incompletely understood. We hypothesized that increased arterial stiffness and maladaptive carotid arterial remodeling may underlie this association....

Acute ischemic stroke (AIS) is defined as sudden onset of a neurologic deficit. It’s the cause of about 85% of all strokes and the deficits last for more than 24 h. (1) Blood pressure (BP) is elevated in 75% or more of patients with acute stroke and different levels of peripheral BP at onset are associated...

Introduction: Increased arterial stiffness (AS) in adults causes increased left ventricular (LV) afterload, putting additional strain on the heart. Long-term, this can lead to an adverse cardiovascular phenotype and AS has been found to be a determinant of CVD, independent of traditional cardiovascular...

Ultra-high-speed motors play a very important role in machine tools. A speed-sensor-less ultra-high-speed motor driver is proposed in this paper. Without any speed sensor that is extremely expensive, the proposed driver employing a sensor-less estimation scheme can perform a closed-loop control very...
