the aim of the present study was to determine psychometric properties of the persian version of the group conflict questionnaire in male and female athletes. for this purpose, 281 athletes at different skill levels in 25 team and individual sports were selected through cluster random sampling method and were asked to complete the persian version of this questionnaire. firstly, the accuracy of t...

Person re-identification (re-id) aims to match pedestrians observed by disjoint camera views. It attracts increasing attention in computer vision due to its importance to surveillance system. To combat the major challenge of cross-view visual variations, deep embedding approaches are proposed by learning a compact feature space from images such that the Euclidean distances correspond to their c...

conclusions although postoperative intra-articular meperidine is a better alternative for bupivacaine, their combination could improve their analgesic effects compared with each other alone. results the bupivacaine-meperidine group had better duration of postoperative analgesia (p = 0.001), latter first analgesic request (p ≤ 0.001), lower total fentanyl consumption in first 24 hours after the ...

Re-identifying the same person in different images is a distinct challenge for visual surveillance systems. Building an accurate correspondence between highly variable images requires a suitable dissimilarity measure. To date, most existing measures have used adapted distance based on a learned metric. Unfortunately, real-world human image data, which tends to show large intra-class variations ...

introduction: measuring the size of motor evoked potentials (meps) induced by transcranial magnetic stimulation (tms) is an investigational technique to show the level of corticospinal excitability however, some of the fundamental methodological aspects of tms (such as the effects of inter-pulse intervals (ipi) on mep size) are not fully understood, this issue raises concerns about the reliabil...

The bag-of-visual-words (BOVW) approaches are widely used in human action recognition. Usually, large vocabulary size of the BOVW is more discriminative for inter-class action classification while small one is more robust to noise and thus tolerant to the intra-class invariance. In this pape, we propose a pyramid vocabulary tree to model local spatio-temporal features, which can characterize th...

Villonodular synovitis is a rare benign condition characterized by villous or nodular hyperplasia of the synovial of unknown etiology. It causes pain and articular swelling. MRI is the imaging modality of choice in patients with a clinical suspicion of villonodular synovitis, but histopathological examination gives definitive diagnosis. Its natural evolution is marked by a high rate of recurren...

Linear discriminant analysis (LDA) is a well-known scheme for supervised subspace learning. It has been widely used in the applications of computer vision and pattern recognition. However, an intrinsic limitation of LDA is the sensitivity to the presence of outliers, due to using the Frobenius norm to measure the inter-class and intra-class distances. In this paper, we propose a novel rotationa...

BACKGROUND The purpose of this study was to examine the inter- and intra-rater reliability of an electronic inspiratory loading device for the assessment of pulmonary functions: maximum inspiratory pressure, peak inspiratory flow, and vital capacity. MATERIAL/METHODS Subjects were 50 patient volunteers in a rehabilitation hospital who had experienced their first episode of unilateral stroke w...
