PURPOSE To screen for keratoconus and potential associated risk factors in a tertiary student population sample. POPULATION AND METHODS This cross sectional study included 1234 students attending An-Najah National University (Nablus, West Bank, Palestine), that were randomly selected from a total of 20,000 university students. 634 (51.3%) student participants responded by completing a self-ad...

The unique event related brain potential (ERP) called the eye fixation related potential (EFRP) is obtained with averaging EEGs at terminations of saccadic eye movements. Firstly, authors reviewed some studies on EFRP in games and in ergonomics and, secondly introduced a new system for assessment of visual entertainments by using EFRP. The distinctive feature of the system is that we can measur...

The largest underground neutrino observatory, Super-Kamiokande, located near Kamioka, Japan has been collecting data since April 1996. It is located at a depth of roughly 2.7 kmwe in a zinc mine under a mountain, and has an effective area for detecting entering-stopping and through-going muons of about 1238 m 2 for muons of > 1.7 GeV. These events are collected at a rate of 1.5 per day from the...

Reconstruction of damaged nerves remains a significant unmet challenge in clinical medicine. To foster improvements, the control of neural stem cell (NSC) behaviors, including migration, proliferation and differentiation are critical factors to consider. Topographical and mechanical stimulation based on the control of biomaterial features is a promising approach, which are usually studied separ...

BACKGROUND The hospital-based stroke registry is useful for understanding diverse clinical characteristics of stroke related to geographical, racial, or environmental differences. METHODS The Khorasan Stroke Registry was established for evaluation of incidence, clinical manifestations, risk factors, topography, and etiology of ischemic stroke in Southern Khorasan, Iran, during 2001 - 2005. Co...

Environmental change caused by urban development, land drainage, agriculture or climate change may result in accelerated decay of in situ archaeological remains. This paper reviews research into impacts of environmental change on hydrological processes of relevance to preservation of archaeological remains in situ. It compares work at rural sites with more complex urban environments. The resear...

In paper industry, the measurement of paper surface topography is important for paper quality control. Noncontact and fast photometric stereo overcomes the disadvantages of the traditional surface topography measurement by the profilometer. In this paper, we present an improvement to three-light photometric stereo for paper surface topography reconstruction. Experiments comparing reconstructed ...

UNLABELLED The brain commonly exhibits spontaneous (i.e., in the absence of a task) fluctuations in neural activity that are correlated across brain regions. It has been established that the spatial structure, or topography, of these intrinsic correlations is in part determined by the fixed anatomical connectivity between regions. However, it remains unclear which factors dynamically sculpt thi...

AF1410 is a low carbon high alloy ultra-high strength steel. It not only has and toughness, but also stress corrosion resistance. However, due to the characteristics of hard quality poor thermal conductivity, difficult material process. In process milling, geometric factors parameters, flexible deformation milling cutter flutter system all affect surface roughness, which makes it predict roughn...
