Roth’s and Andersson’s model (12) supports the conservative neo-Darwinist precept of constant and gradual evolutionary change. They exclude the possibility that mutation rates (per base pair replicated) may be affected by environmental stress (and are thus forced to argue the unimportance of those cells with demonstrably increased mutation rates). However, their model requires that we ignore mu...

iii ACKNOWLEDGMENTS First and foremost, I would like to thank Dr. Tania Roth for being one of the most influential and exceptional mentors I have ever had. Her constant support and guidance has helped me mature both personally and as a researcher. I have learned an unbelievable amount in the past three years as an undergraduate in her lab, and I feel so fortunate and proud to be a part of this ...

Abstract Let $E\subset{\mathbb{R}}$ be a closed set of Hausdorff dimension $\alpha \in (0, 1)$. $P: {\mathbb{R}}\to{\mathbb{R}}$ polynomial without constant term whose degree is bigger than one. We prove that if $E$ supports probability measure satisfying certain condition and Fourier decay condition, then contains three points $x, x+t, x+P(t)$ for some $t>0$. Our result extends the one ...

UNLABELLED Crown discoloration can be induced by root canal sealer remnants following root canal treatment. OBJECTIVE The aim of this study was to evaluate chromatic alterations in human tooth crowns induced by a Mineral Trioxide Aggregate-based sealer (MTA Fillapex®) and a commonly used ZnOE-based sealer (Roth-811). The tested null hypothesis was that the application of the materials did not...
