BACKGROUND Patients with end-stage renal disease are known to have insulin resistance and advanced arterial stiffness. The present study was undertaken to investigate whether insulin resistance was correlated with carotid arterial stiffness in hemodialysis patients. METHODS Eighty nondiabetic hemodialysis patients were recruited. Stiffness index beta of(More)
Pentosidine is an advanced glycation end product (AGE). The present study was undertaken to investigate the association of serum pentosidine with carotid distensibility as a measure of arterial stiffness in hemodialysis patients. One hundred and three patients on maintenance hemodialysis were recruited. The distensibility coefficient of the common carotid(More)
This paper presents an equivalence between feasible kinodynamic planning and optimal kinodynamic planning, in that any optimal planning problem can be transformed into a series of feasible planning problems in a state-cost space whose solutions approach the optimum. This transformation gives rise to a meta-algorithm that produces an asymptotically optimal(More)

Convolutional neural networks (CNN) are a deep learning technique that has achieved state-of-the-art prediction performance in computer vision and robotics, but assume the input data can be formatted as an image or video (e.g. predicting a robot grasping location given RGB-D image input). This paper considers the problem of augmenting a traditional CNN for(More)
Chronic kidney disease (CKD) is associated with a high prevalence of stroke, and reduced estimated glomerular filtration rate (eGFR) can be a strong predictor of higher recurrence, comorbidity, and mortality among patients with acute ischemic stroke. As the backbone of P2Y12 inhibition, clopidogrel is often recommended for preventing stroke, especially in(More)
We present a framework for representing scenarios with complex object interactions, in which a robot cannot directly interact with the object it wishes to control, but must instead do so via intermediate objects. For example, a robot learning to drive a car can only indirectly change its pose, by rotating the steering wheel. We formalize such complex(More)
BACKGROUND AND PURPOSE Patients with chronic kidney disease (CKD) are at a particularly high risk for ischemic and bleeding events. Limited data exist as to the efficacy and safety of clopidogrel in stroke patients with renal dysfunction. Therefore, we sought to assess the impact of decreased kidney function on clinical outcomes for stroke patients on(More)
