End-to-End Enforcement of Erasure and Declassification
(Institute of Electrical and Electronics Engineers Computer Society, 2008)Declassification occurs when the confidentiality of information is weakened; erasure occurs when the confidentiality of information is strengthened, perhaps to the point of completely removing the information from the ... -
Endangered Right Whales Enhance Primary Productivity in the Bay of Fundy
(Public Library of Science, 2016)Marine mammals have recently been documented as important facilitators of rapid and efficient nutrient recycling in coastal and offshore waters. Whales enhance phytoplankton nutrition by releasing fecal plumes near the ... -
“Endemism” Relative to Space, Time, and Taxonomic Level
(Finnish Zoological and Botanical Publishing Board, 2014)Faunal assemblages consist of immigrants, endemics and long-term residents; changes in proportions of these categories through time reflect general aspects of faunal stability and turnover. To study stability and change ... -
The Ending of the PIE 2 sg. Middle Imperative
(Harrassowitz Verlag, 2006) -
Endocrinology, energetics, and human life history: A synthetic model
(Elsevier BV, 2017)Human life histories are shaped by the allocation of metabolic energy to competing physiological domains. A model framework of the pathways of energy allocation is described and hormonal regulators of allocation along the ... -
Endogenizing Syndromes
(Cambridge University Press, 2007) -
Endogenous agendas and seniority advantage
(2012)We study a legislative assembly that chooses its agenda protocol endogenously. We generalize McKelvey and Riezman’s (1992) seminal theory on seniority in legislatures, by allowing for a large class of ordinal agenda rules ... -
Endogenous Entry, Product Variety, and Business Cycles
(The University of Chicago Press, 2012)This paper builds a framework for the analysis of macroeconomic fluctuations that incorporates the endogenous determination of the number of producers and products over the business cycle. Economic expansions induce higher ... -
Endogenous hydrogen peroxide production in the epithelium of the developing embryonic lens
(Molecular Vision, 2014)Purpose Hydrogen peroxide (H2O2) is an endogenously produced reactive oxygen species (ROS) present in a variety of mammalian systems. This particular ROS can play dichotomous roles, being beneficial in some cases and ... -
Endogenous Political Institutions
(MIT Press, 2004)A fundamental aspect of institutional design is how much society chooses to delegate unchecked power to its leaders. If, once elected, a leader cannot be restrained, society runs the risk of a tyranny of the majority, if ... -
Endothelin-1 supports clonal derivation and expansion of cardiovascular progenitors derived from human embryonic stem cells
(Nature Publishing Group, 2016)Coronary arteriogenesis is a central step in cardiogenesis, requiring coordinated generation and integration of endothelial cell and vascular smooth muscle cells. At present, it is unclear whether the cell fate programme ... -
The Enduring Impact of the American Dust Bowl: Short- and Long-Run Adjustments to Environmental Catastrophe
(American Economic Association, 2012)The 1930s American Dust Bowl was an environmental catastrophe that greatly eroded sections of the Plains. The Dust Bowl is estimated to have immediately, substantially, and persistently reduced agricultural land values and ... -
Energetic N+ ions in the interstellar medium
(Oxford University Press, 1987) -
The Energetic Significance of Cooking
(Wiley-Blackwell, 2009)While cooking has long been argued to improve the diet, the nature of the improvement has not been well defined. As a result, the evolutionary significance of cooking has variously been proposed as being substantial or ... -
Energetic, vibrational, and electronic properties of silicon using a nonorthogonal tight-binding model
(American Physical Society, 2000)We present calculations of energetic, electronic, and vibrational properties of silicon using a nonorthogonal tight-binding (TB) model derived to fit accurately first-principles calculations. Although it was fit only to a ... -
Energetics and the evolution of carnivorous plants - Darwin's "most wonderful plants in the world"
(Oxford University Press, 2009)Carnivory has evolved independently at least six times in five angiosperm orders. In spite of these independent origins, there is a remarkable morphological convergence of carnivorous plant traps and physiological convergence ... -
Energetics of Defects and Diffusion Mechanisms in Graphite
(American Physical Society, 1988)Extensive first-principles calculations are presented for the formation energies and migration barriers of elementary defects in graphite, as well as for the activation energy of atomic exchange. The calculations show that ... -
Energetics of hydrogen impurities in aluminum and their effect on mechanical properties
(American Physical Society, 2002)The effects of hydrogen impurities in the bulk and on the surface of aluminum are theoretically investigated. Within the framework of density-functional theory, we have obtained the dependence on 14 concentration of the ... -
Energetics of Protein–DNA Interactions
(Oxford University Press, 2007)Protein–DNA interactions are vital for many processes in living cells, especially transcriptional regulation and DNA modification. To further our understanding of these important processes on the microscopic level, it is ... -
Energetics, Reproductive Ecology, and Human Evolution
(Paleoanthropology Society / University of Pennsylvania Museum of Archaeology and Anthropology, 2008)Human reproductive ecology is a relatively new subfield of human evolutionary biology focusing on the responsiveness of the human reproductive system to ecological variables. Many of the advances in human, and more recently ...
