Thermal Fluctuations in a Charged AdS Black Hole

In this paper, we will analyze the effects of thermal fluctuations on a charged AdS black hole. This will be done by analyzing the corrections to black hole thermodynamics due to these thermal fluctuations. We will demonstrate that the entropy of this black hole get corrected by logarithmic term. We will also calculate other corrections to other important thermodynamic quantities for this black hole. Finally, we will use the corrected value of the specific heat to analyze the phase transition in this system.Comment: 11 pages, Accepted for publication in EP

ECONOMICS OF WHEAT-FALLOW CROPPING SYSTEMS IN WESTERN NORTH DAKOTA

Income and risk aspects of wheat-fallow cropping systems are analyzed in western North Dakota. A wheat yield trend estimation model based on county yields (1950-77) is developed using independent variables of year, annual precipitation, acres of nonfallowed wheat and a dummy variable for fallow and nonfallow practices. The year-to-year change in wheat yields on fallowed and nonfallowed land indicates that summer fallow is becoming less desirable economically. Based on 1980 costs and yields, summer fallow maximizes returns to land at low yields, low wheat prices, and high nitrogen prices. Income variability is reduced under summer fallow.Crop Production/Industries,

Quintessential Quartic Quasi-topological Quartet

We construct the quartic version of generalized quasi-topological gravity, which was recently constructed to cubic order in arXiv: 1703.01631. This class of theories includes Lovelock gravity and a known form of quartic quasi-topological gravity as special cases and possess a number of remarkable properties: (i) In vacuum, or in the presence of suitable matter, there is a single independent field equation which is a total derivative. (ii) At the linearized level, the equations of motion on a maximally symmetric background are second order, coinciding with the linearized Einstein equations up to a redefinition of Newton's constant. Therefore, these theories propagate only the massless, transverse graviton on a maximally symmetric background. (iii) While the Lovelock and quasi-topological terms are trivial in four dimensions, there exist four new generalized quasi-topological terms (the quartet) that are nontrivial, leading to interesting higher curvature theories in $d \geq 4$ dimensions that appear well suited for holographic study. We construct four dimensional black hole solutions to the theory and study their properties. A study of black brane solutions in arbitrary dimensions reveals that these solutions are modified from the `universal' properties these solutions have. This result may lead to interesting consequences for the dual CFTs.Comment: 46 pages, 1 figure. Discussion of black branes added to section

Charged Dilatonic Black Holes in Gravity's Rainbow

In this paper, we present charged dilatonic black holes in gravity's rainbow. We study geometric and thermodynamic properties of black hole solutions. We also investigate the effects of rainbow functions on different thermodynamic quantities for these charged black holes in dilatonic gravity's rainbow. Then, we demonstrate that first law of thermodynamics is valid for these solutions. After that, we investigate thermal stability of the solutions using canonical ensemble and analyze the effects of different rainbow functions on thermal stability. In addition, we present some arguments regarding the bound and phase transition points in context of geometrical thermodynamics. We also study the phase transition in extended phase space in which cosmological constant is treated as the thermodynamic pressure. Finally, we use another approach to calculate and demonstrate that obtained critical points in extended phase space are representing a second order phase transition for these black holes.Comment: 17 pages with 9 captioned figures: Accepted in EPJ

Path length distribution in two-dimensional causal sets

We study the distribution of maximal-chain lengths between two elements of a causal set and its relationship with the embeddability of the causal set in a region of flat spacetime. We start with causal sets obtained from uniformly distributed points in Minkowski space. After some general considerations we focus on the 2-dimensional case and derive a recursion relation for the expected number of maximal chains $n_k$ as a function of their length $k$ and the total number of points $N$ between the maximal and minimal elements. By studying these theoretical distributions as well as ones generated from simulated sprinklings in Minkowski space we identify two features, the most probable path length or peak of the distribution $k_0$ and its width $\Delta$, which can be used both to provide a measure of the embeddability of the causal set as a uniform distribution of points in Minkowski space and to determine its dimensionality, if the causal set is manifoldlike in that sense. We end with a few simple examples of $n_k$ distributions for non-manifoldlike causal sets.Comment: 9 pages, 5 figure

Dynamic multifactor hubs interact transiently with sites of active transcription in Drosophila embryos.

The regulation of transcription requires the coordination of numerous activities on DNA, yet how transcription factors mediate these activities remains poorly understood. Here, we use lattice light-sheet microscopy to integrate single-molecule and high-speed 4D imaging in developing Drosophila embryos to study the nuclear organization and interactions of the key transcription factors Zelda and Bicoid. In contrast to previous studies suggesting stable, cooperative binding, we show that both factors interact with DNA with surprisingly high off-rates. We find that both factors form dynamic subnuclear hubs, and that Bicoid binding is enriched within Zelda hubs. Remarkably, these hubs are both short lived and interact only transiently with sites of active Bicoid-dependent transcription. Based on our observations, we hypothesize that, beyond simply forming bridges between DNA and the transcription machinery, transcription factors can organize other proteins into hubs that transiently drive multiple activities at their gene targets.Editorial noteThis article has been through an editorial process in which the authors decide how to respond to the issues raised during peer review.

CRT-101.10 Outcomes of Underlying Infiltrative Cardiomyopathy in Percutaneous Coronary Intervention

Background: Evidence on the prognosis of infiltrative cardiomyopathy in patients undergoing percutaneous coronary intervention (PCI) has not been well established. Our objective was to assess the prevalence of infiltrative cardiomyopathy including amyloidosis, sarcoidosis and hemochromatosis in PCI patients and its effect on mortality. Methods: National Inpatient Sample 2016-2019 was used to conduct a retrospective analysis by identifying a cohort of patients who underwent PCI with infiltrative cardiomyopathy using respective ICD-10 codes. Primary outcome was the effect of infiltrative cardiomyopathy on mortality in patients undergoing PCI. Secondary outcomes were the independent predictors of mortality. Multivariate logistic regression model was used for analysis. Results: 1.93 million patients were hospitalized for undergoing PCI, out of which 6270 patients had infiltrative cardiomyopathy (prevalence 0.33%). Subgroup analysis showed that 710 patients had underlying amyloidosis (prevalence 0.04%), 4300 patients had sarcoidosis (prevalence 0.23%) and 1280 patients had hemochromatosis (prevalence 0.07%). Mean age of patients undergoing PCI with infiltrative cardiomyopathy was 61 years, 54% were females and 53.5% were white. Patients undergoing PCI were predominantly males (67%) but patient with infiltrative cardiomyopathy who underwent PCI were predominantly females (54%). Underlying amyloidosis was associated with two fold increased odds of mortality in patients undergoing PCI (OR 2.13, 95% CI 1.08-4.23, p=0.029). While sarcoidosis (OR 1.11, 95% CI 0.73-1.7, p=0.6) and hemochromatosis (OR 0.79, 95% CI 0.32-1.92, p=0.6) were not significantly associated with mortality in patients undergoing PCI. The independent predictors of mortality in patients undergoing PCI with infiltrative cardiomyopathy are arrhythmias (OR 2.59, OR 1.14-5.9, p=0.02), cardiac arrest (OR 10.3, CI 3.8-27.6, p=0.00), pulmonary embolism (OR 5.8, CI 1.06-32.4, p=0.04), kidney disease (OR 4.5, CI 1.99-10.3, p=0.00) and liver disease OR 3.5, CI 1.34-9.1, p=0.01). Conclusion: Prevalence of infiltrative cardiomyopathy in patients undergoing PCI is 0.33%. Amyloidosis is associated with significantly increased odds of mortality in patients undergoing PCI while sarcoidosis and hemochromatosis are not significantly associated with mortality. Arrhythmias, cardiac arrest, pulmonary embolism, kidney and liver disease are independently associated with increased mortality in infiltrative cardiomyopathy patients undergoing PCI
