AGN Feedback models: Correlations with star formation and observational implications of time evolution

We examine the correlation between the star formation rate (SFR) and black hole accretion rate (BHAR) across a suite of different AGN feedback models, using the time evolution of a merger simulation. By considering three different stages of evolution, and a distinction between the nuclear and outer regions of star formation, we consider 63 different cases. Despite many of the feedback models fitting the M-\sigma\ relationship well, there are often distinct differences in the SFR-BHAR correlations, with close to linear trends only being present after the merger. Some of the models also show evolution in the SFR-BHAR parameter space that is at times directly across the long-term averaged SFR-BHAR correlation. This suggests that the observational SFR-BHAR correlation found for ensembles of galaxies is an approximate statistical trend, as suggested by Hickox et al. Decomposing the SFR into nuclear and outer components also highlights notable differences between models and there is only modest agreement with observational studies examining this in Seyfert galaxies. For the fraction of the black hole mass growth from the merger event relative to the final black hole mass, we find as much as a factor of three variation among models. This also translates into a similar variation in the post-starburst black hole mass growth. Overall, we find that while qualitative features are often similar amongst models, precise quantitative analysis shows there can be quite distinct differences.Comment: Accepted to MNRAS.

Complete Health Improvement Program to Implement Lifestyle Medicine

The health of many Americans continues to worsen. Over the past 20 years there has been a fifty percent increase in the incidence of Type 2 Diabetes Mellitus in the US. America has an increase in obesity rates, and lower mortality rates compared to other countries that spend less per capita. Currently the US healthcare system only contributes about 20% of the overall care of patients. Provider burned out is increasing and many remain uneducated regarding lifestyle medicine. Since up to 90% of chronic diseases are lifestyle related, a different approach to chronic disease care is needed. The Complete Health Improvement Program (CHIP) is an international program that can aid providers to address lifestyle as part of their overall care. This project will show how implementing CHIP as lifestyle medicine in a group setting can improve the overall risk factors for cardiovascular disease, including weight, body mass index, blood pressure, cholesterol levels, and blood glucose levels in participants. In addition, this project will show the feasibility for reimbursement of CHIP through group visits

Cable TV\u27s Must Carry Rules: The Most Restrictive Alternative - \u3cem\u3eQuincy Cable TV, Inc. v. FCC\u3c/em\u3e

This note first argues that the court correctly applied the least scrutinizing first amendment test to the facts of the case and concluded its inquiry after the rules failed that test. Second, this note argues that the FCC, while once on the correct regulatory path regarding cable, erred by not studying the potential impact of cable television on a case by case basis as the FCC had decided to do with competing broadcasters in Carroll Broadcasting, Inc. v. FCC. Third, this note concludes that the Quincy case will benefit cable operators financially and will provide proper protection of cable operators\u27 right of free speech

Boron Nitride Thin Films from High Energy Gas Phase Reactants

A novel method for generating boron nitride thin films is currently being developed. This method utilizes the energy stored in the precursor molecules to grow films at low temperatures. The mechanism for film growth has been studied, both experimentally and computationally, with promising results

Unraveling the International Law of Colonialism: Lessons From Australia and the United States

In the 1823 decision of Johnson v. M’Intosh, Chief Justice John Marshall formulated the international law of colonialism. Known as the Doctrine of Discovery, Marshall’s opinion drew on the practices of European nations during the Age of Exploration to legitimize European acquisition of territory owned and occupied by Indigenous peoples. Two centuries later, Johnson—and the international law of colonialism—remains good law throughout the world. In this Article we examine how the Doctrine of Discovery was adapted and applied in Australia and the United States. As Indigenous peoples continue to press for a re-examination of their relationships with governments, we also consider whether and how the international law of colonialism has been mitigated or unraveled in these two countries. While we find that the Doctrine lingers, close examination provides several important lessons for all Indigenous nations and governments burdened by colonization

Final Report to the Coastal Erosion Abatement Commission, Commonwealth of Virginia concerning the inventory of sand supplies in the southern Chesapeake Bay

This final report to the Coastal Erosion Abatement Commission concerning the inventory of sand supplies in the southern portion of Chesapeake Bay is a continuation of the work reported on in September 1981 (Byrne et al). The report includes technical appendices in addition to the general text
