Background With the development of endoscopic technology, detection rate synchronous multiple primary early esophageal cancer (SMPEEC) is increasing; however, risk factors remain unclear. We aimed to assess clinicopathological characteristics patients with SMPEEC and investigate contributing lesions. Methods A retrospective cohort study was conducted on 911 consecutive who underwent Endoscopic ...
Synchronous carcinoma of the colon is rare but not infrequent. The incidence ranges from 2-5% . Synchronous primary carcinoma of the colon is defined as two or more primary colonic cancers are identified at the same time and confirmed by histological evaluation. The significance of synchronous primaries is not to miss second lesion, patients needs complete screening of the colon and excision of...
Brushless doubly fed machine (BDFM) is indeed an induction machine which has two windings in the stator and a cage rotor with a special design. Due to absence of brushes and slip rings, this machine is considered for the applications needs high reliability, such as wind turbines. In this paper, stead state performance of BDFM in synchronous mode of operation, the most interesting mode of operat...
Stability of synchronous state is a fundamental problem in synchronization. We study Matrix Measure as an approach for investigating of stability of synchronous states of chaotic maps on complex networks. Matrix Measure is a measure which depends on network structure. Using this measure and comparing with synchronization threshold which depends on the function of the map, show us how the synchr...
Inflammatory myofibroblastic tumor (IMT) is a rare entity and a diagnostic challenge with myriad clinical presentations and pathogenetic mechanisms. Isolated occurrences can be at any site in the body; however, only a few cases of IMT with the concomitant appearance of different organs have been published. We report a unique occurrence of bilateral inflammatory myofibroblastic tumor of the lung...
