BACKGROUND A classification of lumbosacral spondylolisthesis has been proposed recently. This classification describes eight distinct types of spondylolisthesis based on the slip grade, the degree of dysplasia, and the sagittal sacro-pelvic balance. The objectives of this study are to assess the reliability of this classification and to propose a new and refined classification. METHODS Standi...

ion and Generalization of 3D structure for recognition in large intra-class variation Gowri Somanath and Chandra Kambhamettu Video/Image Modeling and Synthesis (VIMS) Lab, Department of Computer and Information Sciences, University of Delaware, Newark, DE, USA. http://vims.cis.udel.edu Abstract. Humans have abstract models for object classes which helps recognize previously unseen instances, de...

A successful detection and classification system must have two properties: it should be general enough to compensate for intra-class variability and it should be specific enough to reject false positives. We describe a method to learn class-specific feature detectors that are robust to intra-class variability. These feature detectors enable a representation that can be used to drive a subsequen...

Specific radiological features identified by Brandser and Marsh were selected for the analysis of acetabular fractures according to the classification of Letournel and Judet. The method employs a binary approach that requires the observer to allocate each radiological feature to one of two groups. The inter- and intra-observer variances were assessed. The presence of articular displacement, mar...

this paper analyses the impact of sanctions against iran in addition to other country-specific determinants on intra-industry trade between iran and shanghai cooperation organization (sco) countries over the period 1997-2013. by disentangling total intra-industry trade (iit) into horizontal and vertical iit and after investigating bilateral trade pattern between iran and sco countries, determin...

conclusions categorization of trials based on their classification scheme to investigate the efficacy of classification-based physical therapy could reduce the heterogeneity of trials and allow researchers to understand the contradictory results in this context. results a total of 12 rcts were identified and categorized into four classification schemes. some evidence supporting classification-s...
