Vocal training through singing and acting lessons is known to modify acoustic parameters of the voice. While the effects of singing training have been well documented, the role of acting experience on the singing voice remains unclear. In two experiments, we used linear mixed models to examine the relationships between the relative amounts of acting and singing experience on the acoustics and p...

In this paper, we present a fixed-point theorem in R-complete regular symmetric spaces endowed with locally T-transitive binary relation R using comparison functions that generalizes several relevant existing results. addition, adopt an example to substantiate the genuineness of our newly proved result. Finally, as application main result, establish existence and uniqueness solution periodic bo...

In this article, we introduce the idea of nonlinear Suzuki (F,R?)-contractions, which is patterned after contractive conditions due to [Nonlinear Anal. 71 (2009) 5313-5317] and Wardowski [Fixed Point Theory Appl. (2012) 94:6]. Utilizing our newly introduced contraction, establish some relation theoretic fixed point theorems. Furthermore, adopt an example highlight genuineness proved results. Fi...

In the following study, we analyze the usage of Twitter during four scientific conferences with focus on humanities and computer science. Automated analyses of tweets, retweets and @-messages were performed as well as an intellectual analysis of the tweets’ contents.
