In this paper we consider the problem of classification of the nilpotent class 2 finitely generated torsion free groups up to the geometric equivalence. By a very easy technique it is proved that this problem is equivalent to the problem of classification of the complete (in the Maltsev sense) nilpotent torsion free finite rank groups up to the isomorphism. This result, allows us to once more c...

background and purpose: decision-making process in thoracolumbar and lumbar burst fracture (tlbf) patients with thoracolumbar injury severity and classification score (tlics) > 4 is remained controversial. on the other hand, the question is whether that the oswestry disability index (odi) can be use to assess to clinical outcomes in these patients . we aimed to study the correlation between the...

conclusions our study revealed weak correlation between pe/e-vc and cormack-lehane grade, with 87% sensitivity and 30% specificity. therefore, we concluded that sonographic measurement criteria are not accurate in airway evaluations before anesthesia. results it was observed that correlations between the pre-epiglottic space (pe) and cormack-lehane grades i, ii, and iii were weak. correlations ...

The general setting here is that one would like to understand the classification of manifolds, and related objects such as knots in 3-space. The “classification”means up to an appropriate equivalence, and for definiteness we will consider smooth (i.e. differentiable) manifolds up to diffeomorphism (equivalence by differentiable homeomorphisms). Of course, what one really seeks is an understandi...

background: diabetes has become a daunting health and medical challenge as well as a hefty economic burden for societies over the past decades. this study was designed to shed light on the overall trend of research across iran regarding mental health status of diabetic patients. method: search process of the present study is part of search strategy of iran diabetes research roadmap (idrr) study...

This paper reports on the experiences from evaluation of GALEN methods for mapping of follow-up categories in the domain of thoracic surgery to an existing classification of surgical procedures. The mapping of the aggregated levels or groups of thoracic procedures presents a genuine problem in relation to strict hierarchical classifications, since the follow-up categories not necessarily fit in...

A self-adaptive classifier for efficient text-stream processing is proposed. The proposed classifier adaptively speeds up its classification while processing a given text stream for various NLP tasks. The key idea behind the classifier is to reuse results for past classification problems to solve forthcoming classification problems. A set of classification problems commonly seen in a text strea...

This paper focuses on evaluating the ability and contribution of using backscatter intensity, texture, coherence, and color features extracted from Sentinel-1A data for urban land cover classification and comparing different multi-sensor land cover mapping methods to improve classification accuracy. Both Landsat-8 OLI and Hyperion images were also acquired, in combination with Sentinel-1A data,...

In 2006, Restorff completed the classification of all Cuntz-Krieger algebras with finitely many ideals (i.e., those that are purely infinite) up to stable isomorphism. He left open the questions concerning strong classification up to stable isomorphism and unital classification. In this paper, we address both questions. We show that any isomorphism between the reduced filtered K-theory of two C...
