A central challenge for natural resource management is developing rigorous yet practical approaches for balancing the costs and benefits of diverse human uses of ecosystems. Economic theory has a long history of evaluating tradeoffs in returns from different assets to identify optimal investment strategies. There has been recent progress applying...
Ballast water discharges are a major source of species introductions into marine and estuarine ecosystems. To mitigate the introduction of new invaders into these ecosystems, many agencies are proposing standards that establish upper concentration limits for organisms in ballast discharge. Ideally, ballast discharge standards will be biologically defensible and adequately...
The 2011 M[subscript W] = 9.0 Tohoku-oki earthquake generated a large number of unique soil liquefaction case histories, including cases with strong ground motion recordings on liquefiable or potentially liquefiable soils. We have compiled a list of 22 strong motion stations (SMS) where surface evidence of liquefaction was observed and...
Assistive mobile manipulators have the potential
to one day serve as surrogates and helpers for people with
disabilities, giving them the freedom to perform tasks such as
scratching an itch, picking up a cup, or socializing with their
families. This article introduces a collaborative project with the
goal of putting...
Theories of human behavior are an important but largely untapped resource for software engineering research. They facilitate understanding of human developers’ needs and activities, and thus can serve as a valuable resource to researchers designing software engineering tools. Furthermore, theories abstract beyond specific methods and tools to fundamental principles that...
A framework for understanding the synthesis and catalysis of metabolites and other biochemicals by proteins is crucial for unraveling the physiology of cells. To create such a framework for Zea mays L. subsp. mays (maize), we developed MaizeCyc, a metabolic network of enzyme catalysts, proteins, carbohydrates, lipids, amino acids, secondary...
Hypoxia is increasing in coastal zones worldwide, with acute effects on demersal fish and benthic invertebrate communities in shallow coastal and estuarine habitats. Less studied are the effects of hypoxia on planktonic larvae of open coastal habitats. Climate change projections suggest intensified hypoxia in open coast upwelling systems, such as...
Cancer economic impact is enormous and depending on the stage in which a colon cancer
is detected, five-year survival rates for colon cancer may be as high as 74%, or as low as
6% (American Cancer Society, 2012). Thus early prevention of colon cancer is crucial to
maximize the chances...
DNA methylation is a well-recognized epigenetic mechanism that has been the subject of a growing
body of literature typically focused on the identification and study of profiles of DNA methylation and their
association with human diseases and exposures. In recent years, a number of unsupervised clustering algorithms,
both parametric and...
