The modified $F(R)$ gravity theory with the function $F(R)=-(1/\beta)\ln(1-\beta R)$ is studied. action at small coupling $\beta$ becomes Einstein--Hilbert action. bound on parameter from local tests $\beta\leq 2\times 10^{-6}$ cm$^2$. We find constant curvature solutions and it was shown that de Sitter space unstable but a solution zero Ricci scalar stable. potential mass of field (scalaron) a...

While frame-level audio features, e.g. MFCCs, in combination with the bag-of-frames approach have widely and successfully been used, we use a block processing framework in our submission. In general block-level features have the advantage that they can capture more temporal information than BOF approaches can. We introduce two novel spectral patterns, closely related to the spectrum histogram a...
