    • Adaptive all the way down: Building responsive materials from hierarchies of chemomechanical feedback 

      Grinthal, Alison Elizabeth; Aizenberg, Joanna (Royal Society of Chemistry (RSC), 2013)
      A living organism is a bundle of dynamic, integrated adaptive processes: not only does it continuously respond to constant changes in temperature, sunlight, nutrients, and other features of its environment, but it does so ...
    • Adaptive basis of geographic variation: genetic, phenotypic and environmental differences among beach mouse populations 

      Mullen, L. M.; Vignieri, S; Gore, J. A.; Hoekstra, Hopi E. (The Royal Society, 2009)
      A major goal in evolutionary biology is to understand how and why populations differentiate, both genetically and phenotypically, as they invade a novel habitat. A classical example of adaptation is the pale colour of beach ...
    • Adaptive click-and-cross 

      Li, Louis; Gajos, Krzysztof Z (Association of Computing Machinery, 2014)
      Computer users with impaired dexterity often have difficulty accessing small, densely packed user interface elements. Past research in software-based solutions has mainly employed two approaches: modifying the interface ...
    • Adaptive constructive processes and the future of memory 

      Schacter, Daniel L. (American Psychological Association, 2012)
      Memory serves critical functions in everyday life, but is also prone to error. This article examines adaptive constructive processes, which play a functional role in memory and cognition but can also produce distortions, ...
    • Adaptive coordinate, real-space electronic structure calculations on parallel computers 

      Zumbach, Gil; Modine, N. A.; Kaxiras, Efthimios (Elsevier, 1996)
      We present a method for electronic structure calculations that retains all of the advantages of real space, but addresses the major weakness of a regular grid, i.e., its inability to treat some regions of space with more ...
    • Adaptive Dynamics of Extortion and Compliance 

      Hilbe, Christian; Nowak, Martin A.; Traulsen, Arne (Public Library of Science, 2013)
      Direct reciprocity is a mechanism for the evolution of cooperation. For the iterated prisoner’s dilemma, a new class of strategies has recently been described, the so-called zero-determinant strategies. Using such a strategy, ...
    • Adaptive Evolution as a Predictor of Species-Specific Innate Immune Response 

      Webb, Andrew E.; Gerek, Z. Nevin; Morgan, Claire C.; Walsh, Thomas A.; Loscher, Christine E.; Edwards, Scott V.; O’Connell, Mary J. (Oxford University Press, 2015)
      It has been proposed that positive selection may be associated with protein functional change. For example, human and macaque have different outcomes to HIV infection and it has been shown that residues under positive ...
    • Adaptive Evolution of Fertilization Proteins within a Genus: Variation in ZP2 and ZP3 in Deer Mice (Peromyscus) 

      Turner, Leslie M.; Hoekstra, Hopi E. (Oxford University Press (OUP), 2006)
      Rapid evolution of reproductive proteins has been documented in a wide variety of taxa. In internally fertilized species, knowledge about the evolutionary dynamics of these proteins between closely related taxa is primarily ...
    • Adaptive Evolution of Multiple Traits Through Multiple Mutations at a Single Gene 

      Linnen, Catherine Ramsay; Poh, Yu-Ping; Peterson, Brant K.; Barrett, Rowan; Larson, J. G.; Jensen, J. D.; Hoekstra, Hopi E. (American Association for the Advancement of Science (AAAS), 2013)
      The identification of precise mutations is required for a complete understanding of the underlying molecular and evolutionary mechanisms driving adaptive phenotypic change. Using plasticine models in the field, we show ...
    • An Adaptive Exchange Algorithm for Sampling From Distributions With Intractable Normalizing Constants 

      Liang, Faming; Jin, Ick Hoon; Song, Qifan; Liu, Jun (Informa UK Limited, 2016)
      Sampling from the posterior distribution for a model whose normalizing constant is intractable is a long-standing problem in statistical research. We propose a new algorithm, adaptive auxiliary variable exchange algorithm, ...
    • Adaptive fluid-infused porous films with tunable transparency and wettability 

      Yao, Xi; Hu, Yuhang; Grinthal, Alison Elizabeth; Wong, Tak-Sing; Mahadevan, Lakshminarayanan; Aizenberg, Joanna (Nature Publishing Group, 2013)
      Materials that adapt dynamically to environmental changes are currently limited to two-state switching of single properties, and only a small number of strategies that may lead to materials with continuously adjustable ...
    • Adaptive Greedy Algorithm With Application to Nonlinear Communications 

      Mileounis, Garasimos; Babadi, Behtash; Kalouptsidis, Nicholas; Tarokh, Vahid (Institute of Electrical and Electronics Engineers, 2010)
      Greedy algorithms form an essential tool for compressed sensing. However, their inherent batch mode discourages their use in time-varying environments due to significant complexity and storage requirements. In this paper ...
    • Adaptive Landscape by Environment Interactions Dictate Evolutionary Dynamics in Models of Drug Resistance 

      Ogbunugafor, C. Brandon; Wylie, C. Scott; Diakite, Ibrahim; Weinreich, Daniel M.; Hartl, Daniel L. (Public Library of Science, 2016)
      The adaptive landscape analogy has found practical use in recent years, as many have explored how their understanding can inform therapeutic strategies that subvert the evolution of drug resistance. A major barrier to ...
    • Adaptive Landscapes and Protein Evolution 

      Carneiro, Mauricio; Hartl, Daniel L. (National Academy of Sciences, 2010)
      The principles governing protein evolution under strong selection are important because of the recent history of evolved resistance to insecticides, antibiotics, and vaccines. One experimental approach focuses on studies ...
    • Adaptive Limited-Supply Online Auctions 

      Hajiaghayi, Mohammad T.; Kleinberg, Robert; Parkes, David C. (Association for Computing Machinery, 2004)
      We study a limited-supply online auction problem, in which an auctioneer has k goods to sell and bidders arrive and depart dynamically. We suppose that agent valuations are drawn independently from some unknown distribution ...
    • Adaptive Locomotor Behavior in Larval Zebrafish 

      Portugues, Ruben; Engert, Florian (Frontiers Media SA, 2011)
      In this study we report that larval zebrafish display adaptive locomotor output that can be driven by unexpected visual feedback. We develop a new assay that addresses visuomotor integration in restrained larval zebrafish. ...
    • Adaptive Radiation, Ecological Opportunity, and Evolutionary Determinism 

      Losos, Jonathan (University of Chicago, 2010)
      Adaptive radiation refers to diversification from an ancestral species that produces descendants adapted to use a great variety of distinct ecological niches. In this review, I examine two aspects of adaptive radiation: ...
    • Adaptive Radiation: Contrasting Theory with Data 

      Gavrilets, Sergey; Losos, Jonathan (American Association for the Advancement of Science, 2009)
