In the late nineties several authors suggested that the extra dimensions predicted by string theory might lead to observable effects at high energy colliders. The ATLAS experiment which will start taking data at the LHC in 2007 will be an excellent place to search for such effects. The sensitivity of ATLAS to signatures of Extra Dimensions will be presented.

In young patients with medial knee osteoarthritis (OA), surgical intervention may not be desirable due to preferences to avoid bone cutting procedures, return to high activity levels, and prolong implant survival. The Atlas Knee System was designed to fill the gap between ineffective conservative treatments and invasive surgery. This single-arm study included 26 patients, aged 25 to 65 years, w...

We present a framework to build a High Angular Resolution Diffusion Image (HARDI) Atlas based on a population of HARDIs from different subjects. The method relies on a non-linear group-wise registration algorithm as well as a set of tools to re-orient the gradient directions of individual subjects and re-interpolate their diffusion weighted signal in a canonical gradient direction set in atlas ...

Automated analysis of MRI data of the subregions of the hippocampus requires computational atlases built at a higher resolution than those that are typically used in current neuroimaging studies. Here we describe the construction of a statistical atlas of the hippocampal formation at the subregion level using ultra-high resolution, ex vivo MRI. Fifteen autopsy samples were scanned at 0.13 mm is...

The Higgs Boson Machine Learning Challenge (HiggsML or the Challenge for short) was organized to promote collaboration between high energy physicists and data scientists. The ATLAS experiment at CERN provided simulated data that has been used by physicists in a search for the Higgs boson. The Challenge was organized by a small group of ATLAS physicists and data scientists. It was hosted by Kagg...

Abstract In the western Tafilalt area, eastern Anti-Atlas (Morocco), solutan echinoderms are a major faunal element of most echinoderm Lagerstätten occurring within Lower Ktaoua Formation (late Sandbian–early Katian). For first time, members class Soluta formally described from Morocco and Africa. All solutans identified as Dendrocystites aff. sedgwicki . Three size-related morphotypes, probabl...

OBJECTIVE To assess the degree of applicability of bone age calculated by Greulich & Pyle Atlas in estimation of chronological age for therapeutic and medico legal purposes. METHODS Two Hundred and Twenty children (139 males, 81 females) between ages of 56 and 113 months (4.5 to 9.5 years) were randomly selected from 4 primary schools of Shireen Jinnah & Clifton, Karachi. Digital images of ha...

Positron emission tomography (PET) scanners designed to image animals the size of rats and mice should possess simultaneously high and uniform spatial resolution and high sensitivity. ATLAS (Advanced Technology Laboratory Animal Scanner), a 6.0 cm diameter effective transverse field-of-view (FOV), 2 cm axial FOV ring-type research scanner seeks these goals by surrounding the animal with eightee...

With the high bunch-crossing and interaction rates and potentially large event sizes the experiments at the LHC challenge data acquisition and trigger systems. Within the ATLAS experiment, a multi-level trigger system based on hardware and software is employed to cope with the task of event-rate reduction. This review article gives an overview of the trigger of the ATLAS experiment highlighting...

The Allen Mouse Brain Connectivity Atlas is a three-dimensional, high-resolution map of neural connections in the mouse brain. Axonal projections from a broad range of brain regions were mapped on a standardized platform to generate a comprehensive database of neural projections. Built upon an array of transgenic mice genetically engineered to target specific cell types, the Allen Mouse Brain C...
