Small coupling limit and multiple solutions to the Dirichlet Problem for Yang Mills connections in 4 dimensions - Part I

, 2010
In this paper (Part I) and its sequels (Part II and Part III), we analyze the structure of the space of solutions to the epsilon-Dirichlet problem for the Yang-Mills equations on the 4-dimensional disk, for small values of the coupling constant epsilon ...

Chronic, Environmentally Relevant PM2.5 Exposure Exacerbates Metabolic Dysfunction‐Associated Steatotic Liver Disease and Early‐Stage Renal Dysfunction in a Rodent Model

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT While epidemiological studies link fine particulate matter (PM2.5) exposure to metabolic dysfunction‐associated steatotic liver disease (MASLD) and renal dysfunction, a translational gap exists, as most animal models utilize acute, high‐dose exposures that poorly reflect chronic, moderate‐level human scenarios.

The correlation between air quality and meteorological parameters of Ningbo from 2012 to 2013(2012~2013年宁波市空气质量状况及其与气象条件的关系)

Zhejiang Daxue xuebao. Lixue ban, 2014
统计分析了 2012~2013年宁波城区空气质量指数AQI现状及其与降雨、温度、风、边界层、逆温等20类气象要素的相关性，结果表明：秋冬季是宁波污染天气高发期，夏季空气质量较好，首要污染物主要为PM2.5和O3；与2012年相比，2013年宁波空气质量状况转差，主要表现为3级以上污染天气明显增多、污染程度明显加重.AQI与气象要素相关性显著，特别是与地面风速、边界层水平风速、对流有效位能、降雨量、相对湿度以及连续无雨日数等呈显著相关（相关系数为0.4~0.5）.当边界层的水平风速低于6 m • s-1 ...

Bayesian model averaging over tree-based dependence structures for multivariate extremes

, 2018
Describing the complex dependence structure of extreme phenomena is particularly challenging. To tackle this issue we develop a novel statistical algorithm that describes extremal dependence taking advantage of the inherent hierarchical dependence ...

Linking Environmental Health and Civic Health: An Analysis of Air Pollution and Charitable Giving

Nonprofit Management and Leadership, EarlyView.
ABSTRACT This study examines the effect of air pollution on charitable giving. We suggest that the burdens associated with poor air quality are associated with a dampening of civic and philanthropic engagement. Analyzing 12 years of county‐level data from the United States with fixed‐effects OLS and instrumental variables regressions, we identify a ...

Evaluating the U.S. Air Quality Index as a risk communication tool: Comparing associations of index values with respiratory morbidity among adults in California.

PLoS ONE, 2020
BackgroundThe Air Quality Index (AQI) in the United States is widely used to communicate daily air quality information to the public. While use of the AQI has led to reported changes in individual behaviors, such behavior modifications will only mitigate

Audit Quality From a Service Perspective: A Systematic Literature Review

Accounting Perspectives, EarlyView.
ABSTRACT Audit quality is a multidimensional and latent construct that researchers struggle to evaluate and interpret. This paper follows an interdisciplinary approach by systematically reviewing the literature on audit quality evaluation from a service quality perspective.
