Influence of Fluorocarbon and Hydrocarbon Acyl Groups at the Surface of Bovine Carbonic Anhydrase II on the Kinetics of Denaturation by Sodium Dodecyl Sulfate
(American Chemical Society (ACS), 2011)This paper examines the influence of acylation of the Lys-ε-NH3+ groups of bovine carbonic anhydrase (BCA, EC 4.2.1.1) to Lys-ε-NHCOR (R = −CH3, −CH2CH3, and −CH(CH3)2, −CF3) on the rate of denaturation of this protein in ... -
Influence of Force Fields and Quantum Chemistry Approach on Spectral Densities of BChlain Solution and in FMO Proteins
(American Chemical Society (ACS), 2015)Studies on light-harvesting (LH) systems have attracted much attention after the finding of long-lived quantum coherences in the exciton dynamics of the Fenna–Matthews–Olson (FMO) complex. In this complex, excitation energy ... -
The influence of immersion and presence in early stage engineering designing and building
(Cambridge University Press (CUP), 2014)This paper explores the role of a designer's sense of engagement in early stage design. In the field of virtual reality, presence and immersion are standard measures of an individual's sense of engagement and involvement ... -
Influence of iron doping on tetravalent nickel content in catalytic oxygen evolving films
(National Academy of Sciences, 2017)Iron doping of nickel oxide films results in enhanced activity for promoting the oxygen evolution reaction (OER). Whereas this enhanced activity has been ascribed to a unique iron site within the nickel oxide matrix, we ... -
The influence of land use and climate change on forest biomass and composition in Massachusetts, USA
(Wiley-Blackwell, 2011)Land use and climate change have complex and interacting effects on naturally dynamic forest landscapes. To anticipate and adapt to these changes, it is necessary to understand their individual and aggregate impacts on ... -
The Influence of Language on Thought
(Guilford Press, 1993)Examines traditional interpretations of the hypothesis that language influences thought with emphasis on interpretations by B. L. Whorf. Research is reviewed that disconfirms the hypothesis and that supports the effects ... -
Influence of Material Contrast on Fault Branching Behavior
(American Geophysical Union, 2011)Material contrasts across faults are a common occurrence, and it is important to understand if these material contrasts can influence the path of rupture propagation. Here we examine models, solved numerically, of rupture ... -
The Influence of Personality on Neural Mechanisms of Observational Fear and Reward Learning
(Elsevier, 2008)Fear and reward learning can occur through direct experience or observation. Both channels can enhance survival or create maladaptive behavior. We used fMRI to isolate neural mechanisms of observational fear and reward ... -
Influence of Reduced Carbon Emissions and Oxidation on the Distribution of Atmospheric CO2: Implications for Inversion Analyses
(American Geophysical Union, 2005)Recent inverse analyses constraining carbon fluxes using atmospheric CO2 observations have assumed that the CO2 source from atmospheric oxidation of reduced carbon is released at the surface rather than distributed globally ... -
The Influence of Selection for Protein Stability on dN/dS Estimations
(Oxford University Press, 2014)Understanding the relative contributions of various evolutionary processes—purifying selection, neutral drift, and adaptation—is fundamental to evolutionary biology. A common metric to distinguish these processes is the ... -
The Influence of Social Dependencies on Decision-Making: Initial Investigations with a New Game
(Institute of Electrical and Electronics Engineers (IEEE), 2004)This paper describes a new multi-player computer game, Colored Trails (CT), which may be played by people, computers and heterogeneous groups. CT was designed to enable investigation of properties of decision-making ... -
The Influence of Social Norms and Social Consciousness on Intention Reconciliation
(Elsevier, 2002)Research on resource-bounded agents has established that rational agents need to be able to revise their commitments in light of new opportunities. In the context of collaborative activities, rational agents must be able ... -
Influence of subsurface biosphere on geochemical fluxes from diffuse hydrothermal fluids
(Springer Nature, 2011)Hydrothermal vents along mid-ocean systems host unique, highly productive biological communities, based on microbial chemoautotrophy, that thrive on the sulphur, metals, nitrogen and carbon emitted from the vents into the ... -
The Influence of Successional Processes and Disturbance on the structure of Tsuga canadensis Forests
(Wiley-Blackwell, 2008)Old-growth forests are valuable sources of ecological, conservation, and management information, yet these ecosystems have received little study in New England, due in large part to their regional scarcity. To increase our ... -
Influence of sulfate reduction rates on the Phanerozoic sulfur isotope record
(Proceedings of the National Academy of Sciences, 2013)Phanerozoic levels of atmospheric oxygen relate to the burial histories of organic carbon and pyrite sulfur. The sulfur cycle remains poorly constrained, however, leading to concomitant uncertainties in O2 budgets. Here ... -
The influence of task contexts on the decision-making of humans and computers.
(Springer, 2007)Many environments in which people and computer agents interact involve deploying resources to accomplish tasks and satisfy goals. This paper investigates the way that the context in which decisions are made affects the ... -
Influence of the quantum zero-point motion of a vortex on the electronic spectra of s -wave superconductors
(American Physical Society, 2006)We compute the influence of the quantum zero-point motion of a vortex on the electronic quasiparticle spectra of s-wave superconductors. The vortex is assumed to be pinned by a harmonic potential, and its coupling to the ... -
The Influence of Transient Thermal Gradients and Substrate Constraint on Delamination of Thermal Barrier Coatings
(American Society of Mechanical Engineers, 2013)A systematic study of factors affecting the delamination energy release rate and mode mix of a thermal barrier coating attached to a substrate is presented accounting for the influence of thermal gradients combined with ... -
The Influence of True Polar Wander on Glacial Inception in North America
(Elsevier BV, 2017-03)The impact that long-term changes in Earth's rotation axis relative to the surface geography, or true polar wander (TPW), and continental drift have had in driving cooling of high-latitude North America since the Eocene ... -
Influenza A H1N1 Pandemic Strain Evolution – Divergence and the Potential for Antigenic Drift Variants
(Public Library of Science, 2014)The emergence of a novel A(H1N1) strain in 2009 was the first influenza pandemic of the genomic age, and unprecedented surveillance of the virus provides the opportunity to better understand the evolution of influenza. We ...
