BACKGROUND Fine needle aspiration cytology (FNAC) is an important investigation in preoperative diagnosis of thyroid lesions. Follicular variant of papillary carcinoma thyroid (FVPTC) is a well defined entity in histopathology, but its diagnosis in FNAC is usually missed and is challenging compared to classic papillary thyroid carcinoma. AIMS The purpose of this study is to retrospectively an...

Cooperation is the foundation of many protocols in wireless networks. Without cooperation, the performance of a network significantly decreases. Hence, all nodes in traditional networks are required to cooperate with each other. In this paper, instead of traditional networks, a network of rational and autonomous nodes is considered, which means that each node itself can decide whe...

Boerhaave syndrome (BS) is a spontaneous esophageal perforation and is a life-threating but uncommon disorder. This syndrome involves a transmural perforation and typically occurs after forceful emesis. The prognosis is dependent on rapid diagnosis and correct management. The classic presentation of BS consists of vomiting, subcutaneous emphysema, and lower thoracic pain. However, significant s...

We propose an efficient collusion-attack-resistant position-verification protocol in a new model named multi-channel model. In the multi-channel model, there are lots of communication channels. When a player picks a random channel and sends a short message over it, the message might slip by an adversary with high probability if the adversary does not know the channel beforehand. This idea is mo...

The term auditory scene analysis (ASA) refers to the ability of human listeners to form perceptual representations of the constituent sources in an acoustic mixture, as in the well-known ‘cocktail party’ effect. Accordingly, computational auditory scene analysis (CASA) is the field of study which attempts to replicate ASA in machines. Some CASA systems are closely modelled on the known stages o...
