Locating Environmental Justice Populations: A Method for Identifying Vulnerable Populations in Massachusetts
Environmental Justice Regional Planning In-Justice GIS Vulnerable Populations Hazards
2014/11/11
Environmental Justice is an issue that has been relevant in the mind of the federal government for the past 18 years. Within society, the goal of Environmental Justice looks to prevent the exploitatio...
Joint Modeling and Registration of Cell Populations in Cohorts of High-Dimensional Flow Cytometric Data
Joint Modeling Registration Cell Populations Cohorts High-Dimensional Flow Cytometric Data
2013/6/14
In systems biomedicine, an experimenter encounters different potential sources of variation in data such as individual samples, multiple experimental conditions, and multi-variable network-level respo...
Automatic Estimation of Flux Distributions of Astrophysical Source Populations
Broken power law CDFN X-ray survey Interwoven EM algorithm Likelihood com-putations logN logS Pareto distribution
2013/6/13
In astrophysics a common goal is to infer the flux distribution of populations of scientifically interesting objects such as pulsars or supernovae. In practice, inference for the flux distribution is ...
The Sample Complexity of Search over Multiple Populations
Quickest search rare events SPRT CUSU procedure sparse recovery sequential analysis,sequential thresholding biased coin spectrum sensing multi-armed bandit
2012/11/23
This paper studies the sample complexity of searching over multiple populations. We consider a large number of populations, each corresponding to either distribution P0 or P1. The goal of the search p...
Some Pitman Closeness Properties Pertinent to Symmetric Populations
Pitman closeness order statistics symmetric random variables estimators sample median more peaked distribution ranked set sampling median ranked set sampling
2012/9/19
In this paper, we focus on Pitman closeness probabilities when the estimators are symmetrically distributed about the unknown parameter θ. We first consider two symmetric estimatorsˆθ1andˆθ2...
Effect of high pressure treatment on microbial populations of sliced vacuum-packed cooked ham
High hydrostatic pressure DGGE Weissella viridescens Cooked ham
2012/8/14
In this study, culture-dependent and culture-independent approaches were used to reveal the microbial diversity and dynamic changes occurring in sliced vacuum-packed cooked ham after high pressure pro...

Thousands of social gatherings - online communities – occur via ICTs across the Internet. They use listservers, bulletin boards, instant messaging, blogs, social network and meeting facilitation syste...
Tackling the Underground Economy in Deprived Populations: A Critical Evaluation of the Deterrence Approach
the Underground Economy Deprived Populations the Deterrence Approach
2009/9/30
The aim of this paper is to evaluate critically the public policy approach that seeks to tackle the underground economy in deprived populations by deterring people from engaging in such work by ensuri...
Separating populations with wide data: A spectral analysis
mixture of product distributions clustering small sample spectral analysis
2009/9/16
In this paper, we consider the problem of partitioning a small data sample drawn from a mixture of $k$ product distributions. We are interested in the case that individual features are of low average ...
Development of Yeast Populations during Processing and Ripening of Blue Veined Cheese
blue cheese yeasts lactic acid bacteria identification
2009/3/19
Varieties of blue veined cheese were analyzed regularly during different stages of manufacturing and ripening to determine the origin of contaminating the yeasts present in them, their population dive...
Occurrence of Killer Yeast Strains in Fruit and Berry Wine Yeast Populations
dsRNA immunity killer activity
2009/3/17
Apple, cranberry, chokeberry and Lithuanian red grape wine yeast populations were used for the determination of killer yeast occurrence. According to the tests of the killer characteristics and immuni...
NEW CRITERIA FOR TESTS OF DIMENSIONALITY UNDER ELLIPTICAL POPULATIONS
Elliptical distribution dimensionality multivariate analysis of variance nuisance parameter
2009/3/11
We consider tests of dimensionality in the multivariate analysis of variance (MANOVA). Three types of test criteria (Likelihood-Ratio-type, Lawley-Hotelling-type and Bartlett-Nanda-Pillai-type) are po...
