In this work, we shall present some novel process to measure the similarity between picture fuzzy sets. Firstly, we adopt the concept of intuitionistic fuzzy sets, interval-valued intuitionistic fuzzy sets and picture fuzzy sets. Secondly, we develop some similarity measures between picture fuzzy sets, such as, cosine similarity measure, weighted cosine similarity measure, set-theoretic similar...

Nowadays, picture fuzzy set theory is a flourishing field in mathematics with uncertainty by incorporating the concept of positive, negative and neutral membership degrees an object. A traditional crisp relation represents satisfaction or dissatisfaction relationship, connection correspondence between objects two more sets. However, there are some problems that can’t be solved through classical...

we describe, the first case of phenobarbital-induced dress syndrome presenting as a lichenoïd eruption. a 49-year-old man had received phenobarbital for a cerebral metastasis. twenty-five days later, he developed a purplish skin eruption, odynophagia, oral mucosal erosion and fever. physical examination revealed a cervical lymphadenopathy and facial edema associated to a diffuse violaceous macu...
