Spherically symmetric Einstein-aether perfect fluid models

We investigate spherically symmetric cosmological models in Einstein-aether theory with a tilted (non-comoving) perfect fluid source. We use a 1+3 frame formalism and adopt the comoving aether gauge to derive the evolution equations, which form a well-posed system of first order partial differential equations in two variables. We then introduce normalized variables. The formalism is particularly well-suited for numerical computations and the study of the qualitative properties of the models, which are also solutions of Horava gravity. We study the local stability of the equilibrium points of the resulting dynamical system corresponding to physically realistic inhomogeneous cosmological models and astrophysical objects with values for the parameters which are consistent with current constraints. In particular, we consider dust models in ($\beta-$) normalized variables and derive a reduced (closed) evolution system and we obtain the general evolution equations for the spatially homogeneous Kantowski-Sachs models using appropriate bounded normalized variables. We then analyse these models, with special emphasis on the future asymptotic behaviour for different values of the parameters. Finally, we investigate static models for a mixture of a (necessarily non-tilted) perfect fluid with a barotropic equations of state and a scalar field.Comment: 52 pages, 7 figures.

Midline1 and the development of the cranial peripheral nervous system

Genetic abnormalities involving the skull and facial region account for around 1/3 of birth defects. Opitz BBB/G syndrome is one such disorder that gives rise to craniofacial malformations, as well as midline defects that cause gastrointestinal anomalies. Patients with X-linked Opitz BBB/G syndrome have loss of function mutations in the gene Midline 1 (Mid1). Using a chick model of cranial development, we demonstrate the expression pattern of the chick orthologue of Mid1 and report a novel function for cMid1 in the formation of the cranial ganglia. In order to study the role of cMid1, we ectopically expressed cMid1 in subpopulations of neural crest cells (NCC’s) from rhombomere 4 (r4), normally devoid of the protein. We find that ectopic targeting of cMid1 to r4 NCCs transiently induces the formation of a larger facial ganglion. Subsequent work to down regulate endogenous cMid1 activity in rhombomere 2 demonstrates a reduction in the size of the developing trigeminal ganglia. Current work aimed at elucidating the mechanisms underlying these observations will be presented

The effects of regional insolation differences upon advanced solar thermal electric power plant performance and energy costs

The performance and cost of four 10 MWe advanced solar thermal electric power plants sited in various regions of the continental United States was studied. Each region has different insolation characteristics which result in varying collector field areas, plant performance, capital costs and energy costs. The regional variation in solar plant performance was assessed in relation to the expected rise in the future cost of residential and commercial electricity supplied by conventional utility power systems in the same regions. A discussion of the regional insolation data base is presented along with a description of the solar systems performance and costs. A range for the forecast cost of conventional electricity by region and nationally over the next several decades is given
