Abstract Background: The current study aims to investigate the effects of mindfulness on attention deficit/ hyperactivity disorder (AD/HD). Attention deficit/ hyperactivity disorder is a kind of neurodevelopmental disorder which affects different aspects of life. Children with attention deficit/hyperactivity disorder have problem with working memory, response inhibition, attention and socia...
Coronary artery disease is one of the most common causes of death and disability, afflicting more than 15 million Americans. Although pharmacological advances and revascularization techniques have decreased mortality, many survivors will eventually succumb to heart failure secondary to the residual microvascular perfusion deficit that remains after revascularization. We present a novel system t...
The vortical structures in the rear separation and wake region produced by a micro-ramp that immersed in a supersonic turbulent boundary layer are investigated. The small scale separation was reveled close to the trailing edge and confirms the previous experimental observation. Between the reverse region and surrounding fast moving flow, a three-dimensional shear layer was formed, where vortice...
The article addresses the problem of how semantic information can be upgraded to knowledge. The introductory section explains the technical terminology and the relevant background. Section two argues that, for semantic information to be upgraded to knowledge, it is necessary and sufficient to be embedded in a network of questions and answers that correctly accounts for it. Section three shows t...
In this paper, we address the problem of fair scheduling of packets in Internet routers with input-queued switches. The goal is to ensure that packets of different flows leave a router in proportion to their reservations under heavy traffic. First, we examine the problem when fair queuing is applied only at output link of a router, and verify that this approach is ineffective. Second, we propos...
We contrasted regional cerebral blood flow in matched groups of 30 patients with major depression, 30 patients with Alzheimer's disease and 30 normal controls using the 133Xe inhalation technique. Whereas both the depressed and Alzheimer's disease groups had markedly reduced global cortical blood flow, the Scaled Subprofile Model, developed to identify abnormalities in regional networks, indica...
Clinical Grade, Regional Cerebral Blood Flow and A ngiographical Spasm in the Monkey After Subarachnoid and Subdural Hemorrhage • Subarachnoid and subdural hemorrhage has been induced in the anesthetized monkey by injection of fresh autogenous blood via a needle inserted through a subfrontal twist drill hole. Serial angiographical studies and regional cerebral blood flow (rCBF) determinations w...
abstract objective: to evaluate the association of base deficit (bd) with mortality in traumatized children, and to assess this association in a subgroup of patients with traumatic brain injury (tbi). methods: in this cross-sectional study performed prospectively on a convenience sample of patients under 16 years of age with trauma presenting to an academic level іі trauma center, we obtain...
