Patron-Driven Acquisition et Evidence-Based Acquisition: Comment implémenter ces modèles afin d’étendre l’offre documentaire dans une bibliothèque ?

Nowadays, usage-based acquisition models for e-books, as PDA and EBA, are quite spread and allow libraries to offer wider collections, without acquiring them. A PDA with Ebook Central was implemented in 2019 and a first EBA with Wiley in 2021. The EPFL Lib ...

Drosophila melanogaster cloak their eggs with pheromones, which prevents cannibalism

Yury Tsybin, Laure Menin, Konstantin Nagornov

Oviparous animals across many taxa have evolved diverse strategies that deter egg predation, providing valuable tests of how natural selection mitigates direct fitness loss. Communal egg laying in nonsocial species minimizes egg predation. However, in cann ...

A cell fitness selection model for neuronal survival during development

Gioele La Manno

Developmental cell death plays an important role in the construction of functional neural circuits. In vertebrates, the canonical view proposes a selection of the surviving neurons through stochastic competition for target-derived neurotrophic signals, imp ...

Neighbor predation linked to natural competence fosters the transfer of large genomic regions in Vibrio cholerae

Christian Iseli, Nicolas Jean Philippe Guex, Noémie Matthey, Melanie Blokesch, Candice Stoudmann, Sandrine Stutzmann

Natural competence for transformation is a primary mode of horizontal gene transfer. Competent bacteria are able to absorb free DNA from their surroundings and exchange this DNA against pieces of their own genome when sufficiently homologous. However, the ...

Social network plasticity decreases disease transmission in a eusocial insect

Alessandro Crespi, Laurent Keller

Animal social networks are shaped by multiple selection pressures, including the need to ensure efficient communication and functioning while simultaneously limiting disease transmission. Social animals could potentially further reduce epidemic risk by alt ...

Signatures of selection and environmental adaptation across the goat genome post-domestication

Stéphane Joost, Estelle Rochat

Background: Since goat was domesticated 10,000 years ago, many factors have contributed to the differentiation of goat breeds and these are classified mainly into two types: (i) adaptation to different breeding systems and/or purposes and (ii) adaptation t ...

No need to shout: Effect of signal loudness on sibling communication in barn owls

Xavier Falourd, Hervé Lissek, Patrick Marmaroli, Dorian Cazau

In animal communication, signal loudness is often ignored and seldom measured. We used a playback experiment to examine the role of vocal loudness (i.e., sound pressure level) in sibling to sibling communication of nestling barn owls Tyto alba. In this spe ...

Multigene expression in stable CHO cell pools generated with the piggyBac transposon system

Florian Maria Wurm, David Hacker, Sowmya Balasubramanian

Heterogenous populations of recombinant cells (cell pools) stably expressing 1-4 transgenes were generated from Chinese hamster overy (CHO) cells with the piggyBac (PB) transposon system. The cell pools produced different combinations of three model protei ...

On Non-cooperative Genomic Privacy

Jean-Pierre Hubaux, Mathias Jacques Jean-Marc Humbert, Amalio Telenti, Erman Ayday

Over the last few years, the vast progress in genome sequencing has highly increased the availability of genomic data. Today, individuals can obtain their digital genomic sequences at reasonable prices from many online service providers. Individuals can st ...

Influenza Virus Drug Resistance: A Time-Sampled Population Genetics Perspective

Hyunjin Shim, Jeffrey David Jensen, Claudia Bank, Gregory Bruce Ewing, Matthieu Foll, Anna Ferrer Admetlla

Author Summary In recent years, considerable attention has been given to the evolution of drug resistance in the influenza A H1N1 strain. As a major annual cause of morbidity and mortality, combined with the rapid global spread of drug resistance, influenz ...

On the Prospect of Identifying Adaptive Loci in Recently Bottlenecked Populations

Jeffrey David Jensen

Identifying adaptively important loci in recently bottlenecked populations - be it natural selection acting on a population following the colonization of novel habitats in the wild, or artificial selection during the domestication of a breed - remains a ma ...

MAR Elements and Transposons for Improved Transgene Integration and Expression

Nicolas Mermod, Niamh Harraghy, Déborah Ley

Reliable and long-term expression of transgenes remain significant challenges for gene therapy and biotechnology applications, especially when antibiotic selection procedures are not applicable. In this context, transposons represent attractive gene transf ...

Effects of sharing text selections on gaze recurrence and interaction quality in a pair programming task

Marc-Antoine Nüssli, Patrick Jermann

We present experimental findings from a dual eye-tracking study that illustrate the effect of different ways of sharing se- lection in remote pair-programming scenario. Forty pairs of engineering students had to complete several program under- standing tas ...

Cell biology: a key driver of therapeutic innovation

Oliver Hantschel

All processes associated with cellular function are likely to contribute to disease. Particularly in the cancer field, most major therapeutic innovations have originated from the elucidation of basic molecular mechanisms by academic researchers. Recent bre ...

A Quantitative Test of Hamilton's Rule for the Evolution of Altruism

Dario Floreano, Laurent Keller, Markus Waibel

The evolution of altruism is a fundamental and enduring puzzle in biology. In a seminal paper Hamilton showed that altruism can be selected for when rb − c>0, where c is the fitness cost to the altruist, b is the fitness benefit to the beneficiary, and r i ...

Relatedness influences signal reliability in evolving robots

Dario Floreano, Laurent Keller, Sara Mitri

Communication is an indispensable component of animal societies, yet many open questions remain regarding the factors affecting the evolution and reliability of signalling systems. A potentially important factor is the level of genetic relatedness between ...

Path planning versus cue responding: a bioinspired model of switching between navigation strategies

Ricardo Andres Chavarriaga Lozano

In this paper we describe a new computational model of switching between path-planning and cue-guided navigation strategies. It is based on three main assumptions: (i) the strategies are mediated by separate memory systems that learn independently and in p ...

The evolution of communication in robot societies

Sara Mitri

Communication is fundamental to life on earth. All social organisms, from bacteria to humans, use communicative signals to coordinate their behaviors with members of their own and other species. Despite its key role in social organization, many questions r ...

Genetic Team Composition and Level of Selection in the Evolution of Cooperation

Dario Floreano, Laurent Keller, Markus Waibel

In cooperative multiagent systems, agents interact to solve tasks. Global dynamics of multiagent teams result from local agent interactions, and are complex and difficult to predict. Evolutionary computation has proven a promising approach to the design of ...
