Quasi-static cyclic tests on masonry spandrels

This paper presents the results of an experimental campaign on masonry spandrels. Within this campaign four masonry spandrels were subjected to quasi-static cyclic loading. Two different spandrel configurations were tested. The first configuration comprise ...

Characterizing the Influence of Effective Population Size on the Rate of Adaptation: Gillespie's Darwin Domain

Jeffrey David Jensen

Characterizing the role of effective population size in dictating the rate of adaptive evolution remains a major challenge in evolutionary biology. Depending on the underlying distribution of fitness effects of new mutations, populations of different sizes ...

Mapping of positive selection sites in the HIV-1 genome in the context of RNA and protein structural constraints

Jacques Fellay, Amalio Telenti, Istvan Bartha

Background: The HIV-1 genome is subject to pressures that target the virus resulting in escape and adaptation. On the other hand, there is a requirement for sequence conservation because of functional and structural constraints. Mapping the sites of select ...

Polyploidy and invasion success: trait trade-offs in native and introduced cytotypes of two Asteraceae species

Alexandre Buttler, François Gillet, Aurélie Thébault

Invasion success is favoured by the introduction of pre-adapted genotypes. In addition, novel pressures in the introduced range may lead to phenotypic changes related to fitness or competitive ability of introduced plants. Polyploidy appears to be over-rep ...

Analysis of Co-evolving Gene Families Using Mutually Exclusive Orthologous Modules

Xiuwei Zhang

Coevolutionary networks can encapsulate information about the dynamics of presence and absence of gene families in organisms. Analysis of such networks should reveal fundamental principles underlying the evolution of cellular systems and the functionality ...

Spatio-temporal brain dynamics mediating post-error behavioral adjustments

Fosco Bernasconi

Optimal behavior relies on flexible adaptation to environmental requirements, notably based on the detection of errors. The impact of error detection on subsequent behavior typically manifests as a slowing down of RTs following errors. Precisely how errors ...

Environment - Application - Adaptation: a Community Architecture for Ambient Intelligence

Rémi Emonet

This article considers the software problems of reuse, interoperability and evolution in the context of Ambient Intelligence. A novel approach is introduced: the Environment, Application, Adaptation (EAA) is streamlined for Ambient Intelligence and is evol ...

Structured Sparsity Models for Compressively Sensed Electrocardiogram Signals: A Comparative Study

David Atienza Alonso, Pierre Vandergheynst, Nadia Khaled, Hossein Mamaghanian

We have recently quantified and validated the potential of the emerging compressed sensing (CS) paradigm for real-time energy-efficient electrocardiogram (ECG) compression on resource-constrained sensors. In the present work, we investigate applying sparsi ...

Adaptation reduces variability of the neuronal population code

Eilif Benjamin Muller

Sequences of events in noise-driven excitable systems with slow variables often show serial correlations among their intervals of events. Here, we employ a master equation for generalized non-renewal processes to calculate the interval and count statistics ...

Perspectives on the use of landscape genetics to detect genetic adaptive variation in the field

Stéphane Joost

Understanding the genetic basis of species adaptation in the context of global change poses one of the greatest challenges of this century. Although we have begun to understand the molecular basis of adaptation in those species for which whole genome seque ...
