Parallel Tracking and Mapping on a camera phone
Camera phones are a promising platform for hand-held augmented reality. As their computational resources grow, they are becoming increasingly suitable for visual tracking tasks....
Psychosocial effects of an Ebola outbreak at individual, community and international levels
The 2013-2016 Ebola outbreak in Guinea, Liberia and Sierra Leone was the worst in history with over 28,000 cases and 11,000 deaths. Here we examine the psychosocial consequences...
Cancer Mortality in the United States by Education Level and Race
Cancer death rates vary considerably by level of education. Identifying groups at high risk of death from cancer by level of education as well as by race may be useful in target...
Detergent-insoluble glycolipid microdomains in lymphocytes in the absence of caveolae.
Antibody binding to glycolipids and glycophosphatidylinositol (GPI)-anchored proteins of lymphocytes can trigger activation of specific signal transduction pathways. The finding...
Sociometric Location and Innovativeness: Reformulation and Extension of the Diffusion Model
1968a class, parental encouragement and educational aspirations. American Journal of Sociology 73:559-572. 1968b Parents' education and children's educational aspirations and a...
Two Distinct Populations of Exosomes Are Released from LIM1863 Colon Carcinoma Cell-derived Organoids
Exosomes are naturally occurring biological nanomembranous vesicles (̃40 to 100 nm) of endocytic origin that are released from diverse cell types into the extracellular space. T...
Absolute isotopic abundance ratios and the atomic weight of a reference sample of chromium
Absolute values have been obtained for the isotopic abundance ratios of a reference sample of chromium, using surface emission mass spectrometry. Samples of known isotopic compo...
The Blue Obelisk—Interoperability in Chemical Informatics
The Blue Obelisk Movement (http://www.blueobelisk.org/) is the name used by a diverse Internet group promoting reusable chemistry via open source software development, consisten...
Graph rigidity and distributed formation stabilization of multi-vehicle systems
We provide a graph theoretical framework that allows us to formally define formations of multiple vehicles and the issues arising in uniqueness of graph realizations and its con...
Gaussian Process Priors with Uncertain Inputs Application to Multiple-Step Ahead Time Series Forecasting
We consider the problem of multi-step ahead prediction in time series analysis using the non-parametric Gaussian process model. k-step ahead forecasting of a discrete-time non-l...
