Download or read book Spatio Temporal Modeling for Peak Events of Seasonal Influenza written by Ying Wang and published by . This book was released on 2014 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Influenza is one of the most common infectious diseases with respect to its ability to easily spread from person to person and result in severe complications, or even death. For a typical season, influenza activity often peaks in one, or several weeks which incorporate a high proportion of the cases in an outbreak, and are referred to variously as "peak events", or "peak weeks". To address the significance of peak events behind the seasonal nature of influenza outbreaks, multidisciplinary research has been advocated for investigating the impacts of weather conditions on the occurrence of peak events. Taking 16 Florida counties as a study area, this research provides a series of innovative statistical analysis aiming to: 1) derive an unambiguous and practical definition of Influenza-like Illness (ILI) peak events and statistically characterize their properties extracted from limited historic ILI records, including: annual event density, their timing, magnitude over prescribed thresholds, and duration; 2) identify fine-scale time lags between weather fluctuations and ILI peak activity for various age groups in terms of the established definition of peak events; 3) investigate interplay among daily weather conditions, climate divisions, properties of peak events and daily ILI activity during peak events for age-specific groups in Florida based on the identified time lags. The conceptual framework and satisfactory results of this research will aid public health professionals in improving surveillance and determining optimal periods for cost-effective intervention strategies.
Download or read book Regularized and Multi model Methods for Detecting Spatial and Spatio temporal Clusters with Applications in Epidemiology written by Maria Kamenetsky and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many diseases, there are geographic patterns known as spatial clusters that can indicate areas of elevated or reduced disease risk. Such areas may be indicative of an outbreak or harmful environmental exposures and identifying these clusters can help guide public health interventions. The detection of clusters has typically been approached as a large multiple testing problem, using a spatial or spatio-temporal scan statistic. We recast the spatial and spatio-temporal cluster detection problem in a high-dimensional data analytical framework with Poisson or quasi-Poisson regression with the Lasso penalty. We next extend this to case-control data using a two-step procedure to identify multiple overlapping clusters and illustrate the approach with breast cancer data from the Wisconsin Women's Health Study. We use an information-theoretic approach to select the number of clusters in each neighborhood. We include the identified clusters into a participant-level logistic regression model, allowing us to adjust for known covariates. Lastly, while standard methods are limited to identifying a single correct model, we develop an approach that stacks all single cluster models into an ensemble of models using likelihood-based weights. We calculate confidence bounds for cells inside the cluster using model-averaged tail area intervals, which we compare to several other methods using coverage and confidence bound widths. These approaches not only efficiently identify multiple overlapping clusters, but they also enable us to discern gradients of spatial risk. Our approaches detect both spatial and spatio-temporal overlapping clusters and are flexible in their application to other epidemiologic study designs.

Download or read book Mathematical Models in Biology written by Leah Edelstein-Keshet and published by SIAM. This book was released on 1988-01-01 with total page 629 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical Models in Biology is an introductory book for readers interested in biological applications of mathematics and modeling in biology. A favorite in the mathematical biology community, it shows how relatively simple mathematics can be applied to a variety of models to draw interesting conclusions. Connections are made between diverse biological examples linked by common mathematical themes. A variety of discrete and continuous ordinary and partial differential equation models are explored. Although great advances have taken place in many of the topics covered, the simple lessons contained in this book are still important and informative. Audience: the book does not assume too much background knowledge--essentially some calculus and high-school algebra. It was originally written with third- and fourth-year undergraduate mathematical-biology majors in mind; however, it was picked up by beginning graduate students as well as researchers in math (and some in biology) who wanted to learn about this field.

Download or read book The Arctic in the Anthropocene written by National Research Council and published by National Academies Press. This book was released on 2014-07-31 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Once ice-bound, difficult to access, and largely ignored by the rest of the world, the Arctic is now front and center in the midst of many important questions facing the world today. Our daily weather, what we eat, and coastal flooding are all interconnected with the future of the Arctic. The year 2012 was an astounding year for Arctic change. The summer sea ice volume smashed previous records, losing approximately 75 percent of its value since 1980 and half of its areal coverage. Multiple records were also broken when 97 percent of Greenland's surface experienced melt conditions in 2012, the largest melt extent in the satellite era. Receding ice caps in Arctic Canada are now exposing land surfaces that have been continuously ice covered for more than 40,000 years. What happens in the Arctic has far-reaching implications around the world. Loss of snow and ice exacerbates climate change and is the largest contributor to expected global sea level rise during the next century. Ten percent of the world's fish catches comes from Arctic and sub-Arctic waters. The U.S. Geological Survey estimated that up to 13 percent of the world's remaining oil reserves are in the Arctic. The geologic history of the Arctic may hold vital clues about massive volcanic eruptions and the consequent release of massive amount of coal fly ash that is thought to have caused mass extinctions in the distant past. How will these changes affect the rest of Earth? What research should we invest in to best understand this previously hidden land, manage impacts of change on Arctic communities, and cooperate with researchers from other nations? The Arctic in the Anthropocene reviews research questions previously identified by Arctic researchers, and then highlights the new questions that have emerged in the wake of and expectation of further rapid Arctic change, as well as new capabilities to address them. This report is meant to guide future directions in U.S. Arctic research so that research is targeted on critical scientific and societal questions and conducted as effectively as possible. The Arctic in the Anthropocene identifies both a disciplinary and a cross-cutting research strategy for the next 10 to 20 years, and evaluates infrastructure needs and collaboration opportunities. The climate, biology, and society in the Arctic are changing in rapid, complex, and interactive ways. Understanding the Arctic system has never been more critical; thus, Arctic research has never been more important. This report will be a resource for institutions, funders, policy makers, and students. Written in an engaging style, The Arctic in the Anthropocene paints a picture of one of the last unknown places on this planet, and communicates the excitement and importance of the discoveries and challenges that lie ahead.

Download or read book Error Estimation for Pattern Recognition written by Ulisses M. Braga Neto and published by John Wiley & Sons. This book was released on 2015-06-17 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first of its kind to discuss error estimation with a model-based approach. From the basics of classifiers and error estimators to distributional and Bayesian theory, it covers important topics and essential issues pertaining to the scientific validity of pattern classification. Error Estimation for Pattern Recognition focuses on error estimation, which is a broad and poorly understood topic that reaches all research areas using pattern classification. It includes model-based approaches and discussions of newer error estimators such as bolstered and Bayesian estimators. This book was motivated by the application of pattern recognition to high-throughput data with limited replicates, which is a basic problem now appearing in many areas. The first two chapters cover basic issues in classification error estimation, such as definitions, test-set error estimation, and training-set error estimation. The remaining chapters in this book cover results on the performance and representation of training-set error estimators for various pattern classifiers. Additional features of the book include: • The latest results on the accuracy of error estimation • Performance analysis of re-substitution, cross-validation, and bootstrap error estimators using analytical and simulation approaches • Highly interactive computer-based exercises and end-of-chapter problems This is the first book exclusively about error estimation for pattern recognition. Ulisses M. Braga Neto is an Associate Professor in the Department of Electrical and Computer Engineering at Texas A&M University, USA. He received his PhD in Electrical and Computer Engineering from The Johns Hopkins University. Dr. Braga Neto received an NSF CAREER Award for his work on error estimation for pattern recognition with applications in genomic signal processing. He is an IEEE Senior Member. Edward R.

Download or read book Risk Assessment Methods written by V.T. Covello and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much has already been written about risk assessment. Epidemiologists write books on how risk assessment is used to explore the factors that influence the distribution of disease in populations of people. Toxicologists write books on how risk assess ment involves exposing animals to risk agents and concluding from the results what risks people might experience if similarly exposed. Engineers write books on how risk assessment is utilized to estimate the risks of constructing a new facility such as a nuclear power plant. Statisticians write books on how risk assessment may be used to analyze mortality or accident data to determine risks. There are already many books on risk assessment-the trouble is that they all seem to be about different sUbjects! This book takes another approach. It brings together all the methods for assessing risk into a common framework, thus demonstrating how the various methods relate to one another. This produces four important benefits: • First, it provides a comprehensive reference for risk assessment. This one source offers readers concise explanations of the many methods currently available for describing and quantifying diverse types of risks. • Second, it consistently evaluates and compares available risk assessment methods and identifies their specific strengths and limitations. Understand ing the limitations of risk assessment methods is important. The field is still in its infancy, and the problems with available methods are disappoint ingly numerous. At the same time, risk assessment is being used.
