In theory, evolutionary modularity allows anatomical structures to respond differently to selective regimes, thus promoting morphological diversification. These differences can then influence the rate and direction of phenotypic evolution among structures. Here we use geometric morphometrics and phenotypic matrix statistics to compare rates of craniofacial evolution and estimate evolvability in...
Reaction of 4, 6-dimethoxy-5-nitropyrimidine [I], with refluxing
pyridine, was discovered to yield the methylpyridinium salt of
1, 6-dihydr -4-hydroxy-1-methyl-5-nitro-6-oxopyrimidine [III]. Possible
use of I as a general N-methylating agent was explored. No
appreciable reaction occurred between I and refluxing excess n-butyl
alcohol. Similar reaction involving quinoline failed to yield an...
T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...
The Viennese waltz is widely recognized as one of the most ubiquitous genres in classical piano literature. Despite the common characteristics that most of these waltzes share ---light, melodious themes, three-four meter, and varied tempos --- there is a large distinction between its earlier and later forms. Curiosity about its...
Oregon State laboratories are responsible for a significant portion of the university’s overall resource and energy consumption, and therefore minimizing waste in a sustainable way should be a top priority for the university while aiming for carbon neutrality by 2025. This study addresses major factors that should be considered when...
We give a new characterization of elements in the Veech group of a translation surface. This provides a computational test for Veech group membership. We use this computational test in an algorithm that detects when the Veech group is a lattice (has co-finite area), and in this case computes a...
Development of new research tools is needed to better understand the potential effects of a noisier ocean on individual and populations of marine mammals. Current behavioral response studies utilize ship-mounted sound sources to induce short-term noise-related behavioral responses in tagged animals. Combining the tag with the sound source into an...
