The Evolution of Gene Expression in The Umbrid Fishes: A Comparison of Phylogenies Based Upon Inferred Differences in Structural and Regulatory Genes (Lactate Dehydrogenase, Duplicate, Controller Nodes, Esocidae, Salmoniformes)
… analyses support: (1) a close relationship of Umbra limi and U. pygmaea, (2) a closer relationship of Dallia pectoralis to Novumbra hubbsi than to either of the Umbra species, and (3) a closer relationship of the Dallia-Novumbra lineage to species of Esox, than the Umbra lineage is to the Esox. …

Solar Sailing Adaptive Control Around the Earth-Moon Lagrange Point L4 for Stellar Observations
… L<sub>4</sub> while the spacecraft transits the umbra of the Moon once per lunar synodic month using solar radiation pressure for orbit control. Rather than a single trajectory, we find a family of solutions using solar sailing to observe the solar corona and capture lunar occultations across …

Software Simulation of an Unmanned Vehicle Performing Relative Spacecraft Orbits
… are implemented in a modular form using the UMBRA framework. In addition, an interface between these two simulations is created for the unmanned vehicle to mimic the translational motion of a spacecraft's relative orbit. Finally, some of the limitations and future improvements of the existing …

Antumbra - Concerto for Classical Guitar and Chamber Orchestra
Antumbra (ænt - UHM - bruh) is a concerto for classical guitar and chamber orchestra with programmatic elements based on the toils of self-discovery. The Latin word ‘antumbra’ (‘ant-‘: “before”; ‘umbra’: “shadow”) describes a state where the subject is in situated in both light and shadow, more …

Application of adaptive optics to the spectroscopic investigation of small-scale solar structures
We study bright points, umbral dots and the G-band using a two-dimensional spectrometer and an Adaptive Optics system, which allows us to record high-resolution dopplergrams and residual intensity images. We find evidence that bright points are smaller than 120 km in diameter. Bright points are …
