Analysis of LexA binding sites and transcriptomics in response to genotoxic stress in Leptospira interrogans
(Oxford University Press, 2016-02)We determined the effects of DNA damage caused by ultraviolet radiation on gene expression in Leptospira interrogans using DNA microarrays. These data were integrated with DNA binding in vivo of LexA1, a regulator of the ... -
Analysis of light transport in scattering media
(Institute of Electrical and Electronics Engineers (IEEE), 2010-06)We propose a new method to analyze light transport in homogeneous scattering media. The incident light undergoes multiple bounces in translucent objects, and produces a complex light field. Our method analyzes the light ... -
An Analysis of Likely Scalants in the Treatment of Produced Water from Nova Scotia
(Taylor & Francis, 2014-11)A significant barrier to further use of hydraulic fracturing to recover shale oil and/or gas is the treatment and/or disposal of hypersaline produced water. This work is an analysis of produced water from Nova Scotia, with ... -
An Analysis of Linux Scalability to Many Cores
(USENIX Association, 2010-10)This paper analyzes the scalability of seven system applications (Exim, memcached, Apache, PostgreSQL, gmake, Psearchy, and MapReduce) running on Linux on a 48- core computer. Except for gmake, all applications ... -
An analysis of long-term relationships among count statistics and metrics of synthetic tropical cyclones downscaled from CMIP5 models
(American Geophysical Union (AGU), 2015-08)In a changing climate, the impact of tropical cyclones on the United States Atlantic and Gulf Coasts will be affected both by how intense and how frequent these storms become. The observational record of tropical cyclones ... -
Analysis of mobility homophily in Stockholm based on social network data
(Public Library of Science (PLoS), 2021-03)We present a novel metric for measuring relative connection between parts of a city using geotagged Twitter data as a proxy for co-occurrence of city residents. We find that socioeconomic similarity is a significant predictor ... -
Analysis of mutations in tumor and normal adjacent tissue via fluorescence detection
(Wiley, 2021)© 2020 Wiley Periodicals LLC. Inflammation is a major risk factor for many types of cancer, including colorectal. There are two fundamentally different mechanisms by which inflammation can contribute to carcinogenesis. ... -
