Adaptation and Invention during the Spread of Agriculture to Southwest China
(2013-09-04)The spread of an agricultural lifestyle played a crucial role in the development of social complexity and in defining trajectories of human history. This dissertation presents the results of research into how agricultural ... -
Adaptation and Specialization in the Evolution of Bacterial Metabolism
(2014-06-06)Specialization is a balance of evolutionary adaptation and its accompanying costs. Here we focus on the Lenski Long-Term Evolution Experiment, which has maintained cultures of Escherichia coli in the same, defined seasonal ... -
Adaptation at the output of the chemotaxis signalling pathway
(2012)In the bacterial chemotaxis network, receptor clusters process input1–3, and flagellar motors generate output4. Receptor and motor complexes are coupled by the diffusible protein CheY-P. Receptor output (the steady-state ... -
Adaptation in the forest deer mouse: evolution, genetics, and development
(2015-05-16)Variation in the shape, size, and number of segments along the vertebral column underlies a vast amount of vertebrate diversity. Although the molecular pathways controlling vertebrate segmentation during normal development ... -
Adaptation Kinetics in Bacterial Chemotaxis
(American Society for Microbiology, 1983)Cells of Escherichia coli, tethered to glass by a single flagellum, were subjected to constant flow of a medium containing the attractant alpha-methyl-DL-aspartate. The concentration of this chemical was varied with a ... -
Adaptation of CRISPR nucleases for eukaryotic applications
(Elsevier BV, 2016)Glucan phosphatases are essential for normal starch degradation in plants and glycogen metabolism in mammals. Here we develop two chromogenic methods for the detection of glucan phosphatase activity in situ after non ... -
Adaptation of US maize to temperature variations
(Nature Publishing Group, 2013)High temperatures are associated with reduced crop yields1, 2, and predictions for future warming3 have raised concerns regarding future productivity and food security4, 5, 6, 7, 8. However, the extent to which adaptation ... -
Adaptations to Life on an Oxidizing Planet – insights from the evolutionary ecophysiology of iron-respiring bacteria
(2022-06-06)For more than 1 billion years, life on a young Earth evolved in oceans that were essentially devoid of oxygen (O2) and rich in dissolved, un-oxidized iron (Fe2+). However, with the advent of oxygenic photosynthesis and the ... -
Adapting Fairness-Intervention Algorithms to Missing Data
(2023-06-30)Missing values in real-world data pose a significant and unique challenge to algorithmic fairness. Different demographic groups may be unequally affected by missing data, and standard procedures for handling missing values ... -
Adapting Quantitative Protein and Phosphorylation Analyses to a Proteome-Wide Scale
(2013-09-30)Liquid chromatography coupled tandem mass spectrometry (LC-MS/MS) has become the preferred method for large-scale peptide and phosphopeptide identification and quantification. The dominance of LC-MS/MS is the result of ... -
Adapting Sequence Models for Sentence Correction
(Association for Computational Linguistics, 2017)In a controlled experiment of sequence-to-sequence approaches for the task of sentence correction, we find that character-based models are generally more effective than word-based models and models that encode subword ... -
Adapting to Adaptations: Behavioural Strategies that are Robust to Mutations and Other Organisational-Transformations
(Nature Publishing Group, 2016)Genetic mutations, infection by parasites or symbionts, and other events can transform the way that an organism’s internal state changes in response to a given environment. We use a minimalistic computational model to ... -
Adapting to Agents' Personalities in Negotiation
(2005)To establish cooperative relationships, agents must be willing to engage in helpful behavior and to keep their commitments with agents who reciprocate this behavior. However, in uncertain and dynamic environments, it is ... -
Adapting Verified Compilation for Target-Language Errors
(2022-02-24)Verified compilers have the potential to greatly improve users’ trust in their code by providing machine-checked proofs of compiler correctness. In recent years they have become increasingly sophisticated and practical, ... -
An Adaptive Agent for Negotiating with People in Different Cultures
(Association for Computing Machinery, 2011)The rapid dissemination of technology such as the Internet across geographical and ethnic lines is opening up opportunities for computer agents to negotiate with people of diverse cultural and organizational affiliations. ... -
Adaptive Algorithms for Sparse Nonlinear Channel Estimation
(2009)In this paper, we consider the estimation of sparse nonlinear communication channels. Transmission over the channels is represented by sparse Volterra models that incorporate the effect of Power Amplifiers. Channel estimation ... -
Adaptive all the way down: Building responsive materials from hierarchies of chemomechanical feedback
(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
(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
(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
(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, ...
