Explicit formulas for the generalized Hermite polynomials in superspace

We provide explicit formulas for the orthogonal eigenfunctions of the supersymmetric extension of the rational Calogero-Moser-Sutherland model with harmonic confinement, i.e., the generalized Hermite (or Hi-Jack) polynomials in superspace. The construction relies on the triangular action of the Hamiltonian on the supermonomial basis. This translates into determinantal expressions for the Hamiltonian's eigenfunctions.Comment: 19 pages.

Treaty Termination and the Presidency: Using Custom to Solve Separation of Powers Disputes

The debate over whether the President, the Senate, or the Congress has primacy in treaty termination remains unsettled. Professor Curtis Bradley incorrectly argues that custom supports a presidential authority to terminate treaties independently. This paper argues that a fuller view of custom, combined with the Intent of the Framers and functional considerations, shows treaty termination is a shared executive-legislative power

A Genre Analysis of National Endowment for the Humanities Nonprofit-Project Grant Proposals

To reveal how writers can craft effective nonprofit grant proposals the study examined proposal narratives for which the U.S. National Endowment For The Humanities (NEH) had awarded financial grants to nonprofit organizations. The study identified the rhetorical moves that the various proposal authors had made as steps toward persuading NEH to award grants

The Effect of Physical Activity and S-equol on Neurogenesis in the HIV-1 Transgenic Rat

The aim of this thesis is to investigate the effect of physical activity and the administration of s-equol on rates of neurogenesis in HIV-1 transgenic rats. HIV-1 is a neurodegenerative disease that leads to the wide range of cognitive impairment described as HAND. Neurogenesis is a newly discovered process that involves the birth of new neurons during our adult life within the dentate gyrus of the hippocampus. Therefore, inducing neurogenesis may be a proper therapeutic that can mitigate some of the cognitive destruction seen as a result of HIV-1 infection. Physical activity has shown to increase the rate of neurogenesis by activating BDNF proteins that stimulate brain plasticity. We used wheel running to investigate if physical activity may increase neurogenesis in our HIV-1 infected rat. S-equol has shown restorative and protective benefits for neurons. We hoped that oral doses of s-equol pellets could assist young neurons in maturation and thus, assist in successful neurogenesis. To investigate rates of neurogenesis, we used immunohistochemical techniques to stain for the doublecortin protein, which exists in neurons as they migrate between 2 and 8 weeks after birth. Tagging these proteins would indicate recent birth of neurons as a result of our experimental condition. The results indicate only a few significant effects from the introduction of physical activity and s-equol. In our rodents exposed to physical activity, we found significant effects on total counts suggesting that males grow more neurons than females, and on location of recently grown neurons with more cell counts on the ventral blade of the dentate gyrus. For animals introduced to s-equol, we found significant effects in the F344 control animals suggesting that s-equol treatment increases rates of neurogenesis in the dorsal blade of the dentate gyrus, and an interaction between location of neurons and treatment group. Between the two experiments, we did not find a significant effect of physical activity or s-equol on increasing neurogenesis in the HIV-1 transgenic animals

The observed day-to-day variability of Mars water vapor

The diurnal variability of atmospheric water vapor as derived from the Viking MAWD data is discussed. The detection of day to day variability of atmospheric water would be a significant finding since it would place constraints on the nature of surface reservoirs. Unfortunately, the diurnal variability seen by the MAWD experiment is well correlated with the occurrence of dust and/or ice hazes, making it difficult to separate real variations from observational effects. Analysis of the day to day variability of water vapor in the Martian atmosphere suggests that the observations are, at certain locations and seasons, significantly affected by the presence of water-ice hazes. Because such effects are generally limited to specific locations, such as Tharsis, Lunae Planum, and the polar cap edge during the spring, the seasonal and latitudinal trends in water vapor that have been previously reported are not significantly affected

MPD thruster technology

MPD (MagnetoPlasmaDynamic) thrusters demonstrated between 2000 and 7000 seconds specific impulse at efficiencies approaching 40 percent, and were operated continuously at power levels over 500 kW. These demonstrated capabilities, combined with the simplicity and robustness of the thruster, make them attractive candidates for application to both unmanned and manned orbit raising, lunar, and planetary missions. To date, however, only a limited number of thruster configurations, propellants, and operating conditions were studied. The present status of MPD research is reviewed, including developments in the measured performance levels and electrode erosion rates. Theoretical studies of the thruster dynamics are also described. Significant progress was made in establishing empirical scaling laws, performance and lifetime limitations and in the development of numerical codes to simulate the flow field and electrode processes

I can’t give you a brain, but I can give you a diploma

Father Laurence LaPointe, Roman Catholic chaplain at the College for 33 years and known to most as Father Larry, delivers an inspiring address and in his opening remarks, educates those present on the meaning of Baccalaureate. . . . although the application and audience of the Baccalaureate have morphed over the centuries, the fundamental function remains the same. First, it is a time for contemplative reflection amid the many activities and festivities associated with Commencement and it draws upon the inspirational writings of many cultures and the diversity of formidable performance skills of the graduates. These days, respecting the religious and philosophical diversity of those participating, the Baccalaureate service draws from a very wide variety of sources for its inspiration. Second, the Baccalaureate service is also an opportunity for the College to impart some last words of advice to its graduates in its role as alma mater, “Beloved Mother.

Spin-blockade spectroscopy of a two-level artificial molecule

Coulomb and spin blockade spectroscopy investigations have been performed on an electrostatically defined ``artificial molecule'' connected to spin polarized leads. The molecule is first effectively reduced to a two-level system by placing both constituent atoms at a specific location of the level spectrum. The spin sensitivity of the conductance enables us to identify the electronic spin-states of the two-level molecule. We find in addition that the magnetic field induces variations in the tunnel coupling between the two atoms. The lateral nature of the device is evoked to explain this behavior.Comment: 4 pages, 4 figures; revised version with a minor change in Fig.2 and additional inset in Fig.3.;accepted by PR

Impaired Spatial Reorientation in the 3xTg-AD Mouse Model of Alzheimer's Disease.

In early Alzheimer's disease (AD) spatial navigation is impaired; however, the precise cause of this impairment is unclear. Recent evidence suggests that getting lost is one of the first impairments to emerge in AD. It is possible that getting lost represents a failure to use distal cues to get oriented in space. Therefore, we set out to look for impaired use of distal cues for spatial orientation in a mouse model of amyloidosis (3xTg-AD). To do this, we trained mice to shuttle to the end of a track and back to an enclosed start box to receive a water reward. Then, mice were trained to stop in an unmarked reward zone to receive a brain stimulation reward. The time required to remain in the zone for a reward was increased across training, and the track was positioned in a random start location for each trial. We found that 6-month female, but not 3-month female, 6-month male, or 12-month male, 3xTg-AD mice were impaired. 6-month male and female mice had only intracellular pathology and male mice had less pathology, particularly in the dorsal hippocampus. Thus, AD may cause spatial disorientation as a result of impaired use of landmarks
