Title:

Abstract:

Objective: This study investigated meteorological and demographic factors affecting the length of dengue fever epidemics and the length of time between epidemics in Barbados, Brazil, and Thailand.
Methods: Region-specific meteorological and demographic data were collected for 104 sites from public sources. Fixed effects piecewise logistic event history analysis was used to quantify the effects of time-varying covariates on the duration of inter-epidemic spells and for the duration of epidemics.
Results: Mean monthly temperature was the most important factor affecting the duration of both inter-epidemic spells (beta = 0.543; confidence interval (CI) 0.4954, 0.5906) and epidemic spells (beta = -0.648; CI -0.7553, -0.5405). Drought conditions increased the time between epidemics. Increased temperature hastened the onset of an epidemic, and during an epidemic, higher mean temperature increased the duration of the epidemic.
Conclusions: By using a duration analysis, this study offers a novel approach for investigating the dynamics of dengue fever epidemiology. Furthermore, these results offer new insights into prior findings of a correlation between temperature and the geographic range and vector efficiency of dengue fever.

Title:

Smallest eigenvalue distributions for two classes of beta-Jacobi ensembles

JOURNAL OF MATHEMATICAL PHYSICS, 53 (10):10.1063/1.4748969 OCT 2012

Abstract:

We compute the exact and limiting smallest eigenvalue distributions for two classes of beta-Jacobi ensembles not covered by previous studies. In the general beta case, these distributions are given by multivariate hypergeometric F-2(1)2/beta functions, whose behavior can be analyzed asymptotically for special values of beta which include beta is an element of 2N(+) as well as for beta = 1. Interest in these objects stems from their connections (in the beta = 1, 2 cases) to principal submatrices of Haar-distributed (orthogonal, unitary) matrices appearing in randomized, communication-optimal, fast, and stable algorithms for eigenvalue computations [J. Demmel, I. Dumitriu, and O. Holtz, "Fast linear algebra is stable," Numer. Math. 108, 59-91 (2007); G. Ballard, J. Demmel, and I. Dumitriu, "Minimizing communication for eigenproblems and the singular value decomposition," 2010. Preprint]. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4748969]

Title:

RELATING THE BOTTOM PRESSURE AND THE SURFACE ELEVATION IN THE WATER WAVE PROBLEM

JOURNAL OF NONLINEAR MATHEMATICAL PHYSICS, 19 1 10.1142/S1402925112400141 OCT 2012

Abstract:

An overview is presented of recent progress on the relation between the pressure at the bottom of the flat water bed and the elevation of the free water boundary within the context of the one-dimensional, irrotational water wave problem. We present five different approaches to this problem. All are compared to (1) numerical data for Stokes waves, one-dimensional traveling wave solutions of the full irrotational water wave problem, and (2) experimental data for high-amplitude waves in a long, narrow (i.e. one-dimensional) wave tank.

Annual Review of Genetics

Abstract:

Short segments of identity by descent (IBD) between individuals with no known relationship can be detected using genome-wide single nucleotide polymorphism data and recently developed statistical methodology. Emerging applications for the detected IBD segments include IBD mapping, haplotype phase inference, genotype imputation, and inference of population structure. In this review, we explain the principles behind methods for IBD segment detection, describe recently developed methods, discuss approaches to comparing methods, and give an overview of applications.
