Adapt or Perish: Evolutionary Rescue in a Gradually Deteriorating Environment

Anne-Florence Raphaëlle Bitbol, Loïc Marrec

We investigate the evolutionary rescue of a microbial population in a gradually deteriorating environment, through a combination of analytical calculations and stochastic simulations. We consider a population destined for extinction in the absence of mutan ...

Homogeneous multifocal excitation for high-throughput super-resolution imaging

Pierre Gönczy, Suliana Manley, Kyle Michael Douglass, Khalid Ashraf Mohie Ibrahim, Davide Gambarotto, Paul Guichard, Virginie Hamel, Niccolo Banterle, Dora Mahecic, Denis Fortun

Super-resolution microscopies have become an established tool in biological research. However, imaging throughput remains a main bottleneck in acquiring large datasets required for quantitative biology. Here we describe multifocal flat illumination for fie ...

Understanding Computational Costs of Cellular-Level Brain Tissue Simulations Through Analytical Performance Models

Felix Schürmann, Francesco Cremonesi

Computational modeling and simulation have become essential tools in the quest to better understand the brain's makeup and to decipher the causal interrelations of its components. The breadth of biochemical and biophysical processes and structures in the b ...

Insights into the interfacial carrier behaviour of copper ferrite ( CuFe2O4) photoanodes for solar water oxidation

Kevin Sivula, Liang Yao, Nestor Guijarro Carratala, Florian Le Formal, Yongpeng Liu, Florent Alexandre Boudoire

Designing efficient yet robust photoanodes for water oxidation stands out as a major bottleneck in the realization of a feasible photoelectrochemical tandem cell for solar water splitting. Spinel copper ferrite (CuFe2O4) has been recently reported as a pot ...

Long-term imaging, automated high-content phenotyping and sorting of C. elegans larvae and embryos using microfluidic platforms

Hüseyin Baris Atakan

C. elegans is frequently studied to address fundamental biological questions motivated by its short life cycle, small size, hermaphrodite behavior and well-annotated genome. In this work, we present novel microfluidic platforms that support long-term cultu ...

Mechanics of Allostery: Contrasting the Induced Fit and Population Shift Scenarios

Matthieu Wyart, Solange Marie Flatt, Carolina Brito Carvalho dos Santos, Stefano Zamuner, Riccardo Ravasio

In allosteric proteins, binding a ligand can affect function at a distant location, for example, by changing the binding affinity of a substrate at the active site. The induced fit and population shift models, which differ by the assumed number of stable c ...

Fast Approximate Spectral Clustering for Dynamic Networks

Pierre Vandergheynst, Lionel Jérémie Martin, Andreas Loukas

Spectral clustering is a widely studied problem, yet its complexity is prohibitive for dynamic graphs of even modest size. We claim that it is possible to get information from past cluster assignments to expedite computation. Our approach builds on a recen ...

The Demographic and Adaptive History of the African Green Monkey

Susanne Petra Pfeifer

Relatively little is known about the evolutionary history of the African green monkey (genus Chlorocebus) due to the lack of sampled polymorphism data fromwild populations. Yet, this characterization of genetic diversity is not only critical for a better u ...

The Combined Effect of Oseltamivir and Favipiravir on Influenza A Virus Evolution

Jeffrey David Jensen, Claudia Bank, Sebastian Matuszewski, Nicky Louise Ormond

Influenza virus inflicts a heavy death toll annually and resistance to existing antiviral drugs has generated interest in the development of agents with novel mechanisms of action. Favipiravir is an antiviral drug that acts by increasing the genome-wide mu ...

A heterogeneous evolutionary stable population under assortative matching: Exploring the diversity of preferences

Boris Thurm, Charles Chadi Ayoubi

Recent studies have shown that a population acting not only upon self-interest but also exhibiting some morality preference has an evolutionary advantage. Specifically, in the setting of a symmetric fitness game, a resident population is evolutionary stabl ...
