Falls are a major problem in the elderly population, but few communications address the influence of anesthesia on balance control. This study reports how a general balanced anesthesia (GBA) and a spinal anesthesia (SA) affect balance control in the elderly. We divided into three groups, according to electronystagmography findings and type of anesthesia, 21 men older than 65 years (mean age, 72...

Bayesian networks (BNs) have become an essential tool for reasoning under uncertainty in complex models. In particular, the subclass of Gaussian Bayesian networks (GBNs) can be used to model continuous variables with Gaussian distributions. Here we focus on the task of learning GBNs from data. Factorization of the multivariate Gaussian joint density according to a directed acyclic graph (DAG) p...

This paper presents a new queuing model for performance analysis of go-back-N automatic repeat request (GBN-ARQ) protocol in cooperative wireless networks. In the model, cooperative medium access control (CoopMAC) protocol and dynamic radio link adaptation are taken into consideration. We analyze the probability distribution of the total delay witnessed by packets at the source side. Multi-rate...

Background: The number of people aged 60 and older is increasing faster than other age groups worldwide. Iran will experience a sharp aging population increase in the next decades, and this will pose new challenges to the healthcare system. Since providing high quality aged-care services would be the major concern of the policymakers, this question arises that what types of aged care services s...

Nutraceuticals are increasingly applied to the management of equine arthritis and joint disease, particularly those based upon glucosamine and chondroitin sulphate. While the first report of using glucosamine in horses appeared more than 25 years ago, it was not until 1992 that isolated studies began to be reported. Since that time, 15 in vivo papers have been published in the equine literature...

In this paper, we derive an analytical expression for the packet error probability in a telecommunication scheme with the three-copy majority combining. The derived expression has a closed form and it is applicable in the case of diversity packet transmission over three independent binary symmetric channels with various bit error probabilities. This expression is then used to analyze an example...

The growing interest of mobile computing and communication devices, leads to the needs of wireless broadband networks. Data transmission over such networks requires suitable error control schemes to guarantee high data reliability as well as efficient bandwidth utilization. This paper proposes an accurate but simple analytical approach to evaluate the performance of wireless networks using gate...

Ganglioneuroblastoma (GBN) is a malignant neoplasm of the autonomic nervous system. Adult onset of ganglioneuroblastoma is extremely rare. Only 16 cases have been reported in English literature, to date. Surgery represents the first-line therapy for the treatment of ganglioneuroblastoma. Radiation therapy is indicated in patients with localized unresectable disease. Chemotherapy is reserved for...

ACKNOWLEDGEMENTS I would like to thank Dr. Aria Nosratinia for giving me an opportunity to do research as a graduate student with him. I express my gratitude to Dr. Nosratinia for his support, guidance and advice not only in my work but also in other aspects of my life. It is a wonderful experience to work with him. I would like to thank Dr. Fumagalli and Dr. Fonseka for serving on my superviso...
