CMB Constraints on Principal Components of the Inflaton Potential

We place functional constraints on the shape of the inflaton potential from the cosmic microwave background through a variant of the generalized slow roll approximation that allows large amplitude, rapidly changing deviations from scale-free conditions. Employing a principal component decomposition of the source function G'~3(V'/V)^2 - 2V''/V and keeping only those measured to better than 10% results in 5 nearly independent Gaussian constraints that maybe used to test any single-field inflationary model where such deviations are expected. The first component implies < 3% variations at the 100 Mpc scale. One component shows a 95% CL preference for deviations around the 300 Mpc scale at the ~10% level but the global significance is reduced considering the 5 components examined. This deviation also requires a change in the cold dark matter density which in a flat LCDM model is disfavored by current supernova and Hubble constant data and can be tested with future polarization or high multipole temperature data. Its impact resembles a local running of the tilt from multipoles 30-800 but is only marginally consistent with a constant running beyond this range. For this analysis, we have implemented a ~40x faster WMAP7 likelihood method which we have made publicly available.Comment: 12 pages, 14 figures, submitted to Phys.Rev.D.

Building Blocks in Hierarchical Clustering Scenarios and their Connection with Damped Lyα\alpha Systems

We carried out a comprehensive analysis of the chemical properties of the interstellar medium (ISM) and the stellar population (SP) of current normal galaxies and their progenitors in a hierarchical clustering scenario. We compared the results with observations of Damped Lyman-$\alpha$ systems (DLAs) under the hypothesis that, at least, part of the observed DLAs could originate in the building blocks of today normal galaxies. We used a hydrodynamical cosmological code which includes star formation and chemical enrichment. Galaxy-like objects are identified at $z=0$ and then followed back in time. Random line-of-sights (LOS) are drawn through these structures in order to mimic Damped Lyman $\alpha$ systems. We then analysed the chemical properties of the ISM and SP along the LOS. We found that the progenitors of current galaxies in the field with mean $L <0.5 L^*$ and virial circular velocity of $100-250 {\rm km/sec}$ could be the associated DLA galaxies. For these systems we detected a trend for $$ to increase with redshift.(Abridged)Comment: 15 pages, 11 Postscript figures. Accepted to MNRA

How has diabetes hospitalizations/ICU admissions changed with insulin price increasing over the last 20 years?

Chronic illnesses are a global issue and therefore are a more researched topic around the world, especially if they are common among populations. Most of these illnesses require medications to maintain a good quality of life or even in some cases just to survive. In this study, we will be looking at those who meet the expectations of the latter requirement for prescriptions. More specifically, the illness Diabetes Mellitus and how the prices of insulin in the United States of America are forcing Americans to fast their rations of insulin that are covered by insurance. Risking their own lives with complications like Acute Myocardial Infarction. We will focus on the rates of ICU admissions in the USA for the primary diagnosis being AMI and a secondary diagnosis for DM. We will compare that to countries who are honest about their insulin prices and are labeled as more “healthcare affordable”. Along with providing research around the world of the complications and dangers of fasting insulin doses. The price of Insulin should not come at the cost of American lives, or even take away the quality of those lives when we have medications that can easily improve them. Our country willingly lets people die from preventable diseases just so pharmaceutical companies can be greedy on a population that has no other choice. There is enough evidence to prove that rationing one\u27s insulin while they have diabetes mellitus makes them much more likely to be admitted to the ICU fighting for their life with an acute myocardial infarction
