Revisiting Neutron Star Physics Including Finite Temperature and Density Effects on the Medium
Neutron stars are highly compact stellar evolutionary endpoints whose formation and existence rely on a complex interplay between the overall hydrodynamic equilibrium and the local approach of quantum mechanics. The extreme conditions theorized inside neutron stars seems to set up conditions for the existence of exotic forms of matter. This project aims to develop a better understanding of the dynamics of neutron stars with the eventual goal of developing an improved and testable model for neutron stars. We begin with a brief review of stellar evolution, from molecular cloud, all the way up to core collapse supernovae, where the temperature and densities begin to take on extreme values. We look at weak force interactions during the supernova and then examine their role in determining the equation of state and thermal evolution of a neutron star. We discuss the structure of neutron stars and the different varieties of neutron star systems that have been observed. Finally, we examine the modification of electron properties in the finite temperature and densities encountered in the interiors of neutron stars. We look at the number density of electrons in high temperatures and chemical potentials in the context of neutron star thermal evolution and find that it fits with existing cooling trends

Olivocerebellar connections in the Atlantic stingray
The morphology of the cerebellum in cartilaginous fishes varies from a smooth, relatively simple bi-lobed structure, to an undulated and complex multi-lobed configuration. Little is known about the anatomical connections and functions of the cerebellum in species with a complex cerebellar morphology, such as the Atlantic stingray, which possesses a tri-lobed cerebellum. The forces that drove this elaboration of the cerebellum in stingrays remain unclear. The inferior olive is a major neural center that is found in all vertebrates. Studies in mammals and other vertebrates indicate that the inferior olive has strong neural connections with, and functional influence on, the cerebellum. Therefore, the elaboration of the cerebellar structure in the Atlantic stingray may have been paralleled by an elaboration of the inferior olive inputs to the cerebellum in this species. In the present study the organization of the neural connections between the inferior olive and the three different lobes of the cerebellum in the Atlantic stingray were revealed using neuroanatomical tracing techniques. Compared to studies of the olivo-cerebellar connections in elasmobranch species with a bi-lobed cerebellar structure, there appears to have been an increase in complexity of these connections in the Atlantic stingray. The results of this research contribute to our understanding of the evolution of the brain in cartilaginous fishes, as well as other vertebrates
Maupin Home, Cook St. (1)
Text on back of photo reads "Maupin Home across from City Hall on Cook St. = cut in to two pieces and Marsh movers placed both pas. in Kemah (At Night) This house at one time sat on the corner of 4th & Moskowitz facing East. That intersection is now in the middle of Hwy. 146. It was moved to lots on Cook St. in 1935. The Maupins were living in the house at the time."One of two photographs (front and back) of the Maupin home on Cook St. Kodak paper
