Vascular diseases of the brain are the second reason of the death and the first cause of morbidity and disability worldwide. In tropical areas stroke has some particular features related to the nature of torrid zones. There are some special causes of the stroke, mainly infectious, although some of them are non-infectious. The most important etiologies are malaria, tuberculosis, cysticercosis, s...

Medically unexplained or functional somatic symptoms (FSS) in children constitute a major clinical problem. However, research data on FSS in young children are few, and epidemiological studies are hampered by lack of good standardised measures. The present thesis consists of two studies: In study one, we developed two measures to assess FSS in young children. The first measure is a parent i...

A strong link exists between stratospheric variability and anomalousweather patterns at the earth’s surface. Specifically, during extreme variability of the Arctic polar vortex termed a ‘‘weak vortex event,’’ anomalies can descend from the upper stratosphere to the surface on time scales of weeks. Subsequently the outbreak of cold-air events have been noted in high northern latitudes, as well a...

Social insect colonies use interactions among workers to regulate collective behavior. Harvester ant foragers interact in a chamber just inside the nest entrance, here called the 'entrance chamber'. Previous studies of the activation of foragers in red harvester ants show that an outgoing forager inside the nest experiences an increase in brief antennal contacts before it leaves the nest to for...

The testes develop in the abdomen and descend during the third trimester into the scrotum. The testicle can be arrested anywhere during its descent or it can migrate into an abnormal position. Undescended testis, otherwise known as cryptorchidism, is a welldescribed disorder with a spectrum of complications ranging from torsion to necrosis, infertility, and atrophy. The risk of developing testi...

Akhilesh Tyagi Iowa State University Department of Computer Science Ames, Iowa 50011 E-mail: [email protected] Abstract. The extremely high data rates of optical computing technology (100 Mwords/s and upward) present unprecedented challenges in the dynamic memory design. An optical fiber loop used as a delay line is the best candidate for primary, dynamic memory at this time. However, it pos...

This article firstly attempts to explore parallel algorithms of learning distributed representations for both entities and relations in large-scale knowledge repositories with MapReduce programming model on a multi-core processor. We accelerate the training progress of a canonical knowledge embedding method, i.e. translating embedding (TransE) model, by dividing a whole knowledge repository int...

in recent years, the topic of desertification has been discussed in different ways in scientific areas. this event occurred globally, regionally and nationally and many steps were taken to stop it. desertification is challenged universally and its destructive effects are unavoidable and its consequences do endanger the life of inhabitants. the identification of sensitive regions and prevention ...

A bstract M-theory on local G 2 -manifolds engineers 4d minimally supersymmetric gauge theories. We consider ALE-fibered and study the physics from view point of a partially twisted 7d Yang-Mills theory its Higgs bundle. Euclidean M2-brane instantons descend to non-perturbative effects theory, which are found be in one correspondence with colored quantum mechanics. compute contributions superpo...
