Adversarial attack is a technique for deceiving Machine Learning (ML) models, which provides way to evaluate the adversarial robustness. In practice, algorithms are artificially selected and tuned by human experts break ML system. However, manual selection of attackers tends be sub-optimal, leading mistakenly assessment model security. this paper, new procedure called Composite Attack (CAA) pro...
Recent works have shown that quantum period-finding can be used to break many popular constructions (some block ciphers such as Even-Mansour, multiple MACs and AEs...) in the superposition query model. So far, all broken exhibited a strong algebraic structure, which enables craft periodic function of single input block. Recovering secret period allows recover key, distinguish, confidentiality o...
Abstract Background and purpose: Migraine is a kind of primary headache that involves neurovascular system. Some studies have shown that obesity could affect the severity, frequency and duration of migraine attacks. This study aimed at investigating the association between anthropometric measurements and severity, frequency and duration of headache in patients with migraine. Material and me...
Background and Aim: Migraine headaches, start since adolescence, are often severe and lead to dysfunction in patients. This study was performed to determine the prevalence of migraine and its relationship with educational disability in adolescents of Birjand city in 2010. Materials and Methods: In this descriptive- analytical study, 723 adolescents were selected by cluster sampling metho...
conclusion these data indicate that while ce-mri will depict more positive results, there are cases in which dwi will show a positive result while ce-mri is negative. we suggest that the combination of these two imaging modalities might yield more positive results in diagnosing acute ms attack giving rise to a more accurate diagnosis. results ce-mri yielded positive results for 61 (87%) patient...
