The pivotal role of listening comprehension in second/foreign language learning requires that researchers conduct studies which investigate factors that affect test takers’ performances. The present study was set out to examine whether item modality (i.e., written vs. oral items) affects listening comprehension test performance. In addition, it investigated whether allowing test takers to take ...

in this note, a generalization of higher rank numerical range isintroduced and some of its properties are investigated

In this note we review a simple criterion, due to Ekedahl, for superspecial curves defined over finite fields.Using this we generalize and give some simple proofs for some well-known superspecial curves.

In this short note, we present a refinement of the logarithmic-geometric mean inequality. As an application of our result, we obtain an operator inequality associated with geometric and logarithmic means.

In this note we characterize the compact weighted Frobenius-Perron operator $p$ on $L^1(Sigma)$ and determine their spectra. We also show that every weakly compact weighted Frobenius-Perron operator on $L^1(Sigma)$ is compact.

In cite{beh}, the authors claimed by a counterexample that the cross product definition in cite{molo} is not correct and thus the proposed technique is false. In this note, we show that this assertion is ‎incorrect.
