Marie-Cécile Robert, "Presentation of the CRISPR/CAs9 system"

Résumé

 Marie-Cécile works in the MGC (Montpellier Genomic Collection) plateform of the IGMM. She will introduce us to the famous CRISPR/CAs9 system, its applications and why it is a revolution in molecular biology.

Eric Rivals, "Presentation of the LIRMM survival toolkit"

Résumé

Je propose de présenter quelques outils pratiques pour la survie au LIRMM (mycore, gite.lirmm, filesender, ... et si j'ai le temps org mode).

Marc Chakiachvili, "Why and how to choose your IDE (integrated development environment)"

Résumé

An integrated development environment (IDE) is a software application that provides comprehensive facilities to computer programmers for software development. An IDE normally consists of a source code
editor, build automation tools and a debugger. Most modern IDEs have intelligent code completion. Some IDEs contain a compiler, interpreter, or both. Sometimes a version control system are integrated.
Many modern IDEs also have a class browser, an object browser, and a class hierarchy diagram, for use in object-oriented software development."

Well, that's only Wikipedia IDE definition....

Clearly when developing complex pieces of software, use of an IDE can definitely simplify your programmer's life and reduce the time you spend developing...

- So how and what should you consider before choosing the right IDE for your programs ?
- Simple extensible Text Editor, or choose big and string IDE to ease your development ?
- I'll show you the best ever IDE, everyone should use ! in my opinion, which is obviously unbiased !

Emma Saulnier, "Zombie apocalypse and epidemiological modeling"

Résumé

A Zombie Apocalypse social media campaign by the US Centers for Disease Control and Prevention in May 2011 successfully raised awareness of hurricane domestic preparedness in an audience usually only
marginally receptive to public health messages, through comic-book graphic art and other underused media. We present technologies and applications related to zombie outbreaks modeling.
Les CDC américains ont mené en mai 2011 une campagne médiatique sur les réseaux sociaux intitulé "Zombie Apocalypse".
A travers une BD et d'autres média alternatifs, cette campagne a brillamment accrût la sensibilisation à la préparation aux tempêtes d'une partie de la population généralement peu réceptive aux
messages de santé publique. Nous présenterons ici les technologies et applications liées à la modélisation des épidémies zombie.

Krister Swenson, "Gluing computation experiments together with Snakemake"

Résumé

Do you have a program that operates on data produced by another program?
Snakemake is an efficient way to deal with interactions between a group of programs that depend on each other.
Some benefits of Snakemake are:
 1. python-based syntax (little syntax specific to snakemake)
 2. automatic parallelization of calls
 3. easily rerun only the necessary parts of an experiment after changes to code or input

I will present the basics of Snakemake and go through a simple example.

Rodrigo-antonio Canovas-barroso, "Debate about Compressed Structures"

Résumé

A compressed structure is a data structure modified to take up little space, besides providing direct access
and functionalities to answer certain queries on the stored data without need to decompress them.
Nowadays it has become of vitally important to operate on compressed data.
This is mainly because the information handled has grown exponentially and,
as an aggravating circumstance, secondary storage technology has not evolved enough in terms of speed.
Currently, main memory access is estimated at 10 ns, whereas disk access is estimated at 10^7 ns.
The speed difference is so vast that it is preferable to pay a moderate cost of access to a slower compressed structure,
that it fits in main memory, than to make constant access to disk.

In this context compressed structures make more sense, because by using a smaller space,
more information can be handled in main memory by paying a lower operating cost than
managing the same information efficiently on disk. However, still remains the question
for how long these structures will be still needed.

Clément Agret, "MARIANA: the cutest deep learning framework"

Résumé

VO :As neural nets increase in complexity they also become harder to write and harder to teach. Our hypothesis is that these difficulties stem from the absence of a language that elegantly describe
neural networks.
Mariana (named after the deepest place on earth, the Mariana trench) is an attempt to create such a language within python. That being said, you can also call it an Extendable Python Machine Learning
Framework build on top of Theano. VF :Plus les réseaux neuronaux augmentent en complexité, plus ils deviennent difficiles à écrire et à enseigner. L’hypothèse des développeurs de Mariana est que ces
difficultés proviennent de l'absence d'un langage qui décrit avec simplicité les réseaux de neurones.
Mariana (du nom de l'endroit le plus profond sur terre) est une tentative de créer un tel langage pour python. Cela étant dit, vous pouvez également l'appeler "Python Extensible Machine Learning
Framework" construite sur Theano.

Laurent bréhélin, "Cell biology by the numbers"

Résumé

"One of the central missions of our book is to serve as an entry point
that invites the reader to explore some of the key numbers of cell
biology. We imagine readers of all kinds with different approaches:
seasoned researchers who simply want to find the best values for some
number of interest or beginning biology students who wish to supplement
their introductory course materials. In the pages that follow, we
provide several dozen vignettes, each of which focuses on quantities
that help us think about sizes, concentrations, energies, rates,
information content and other key quantities that describe the living
world." http://book.bionumbers.org/

Fabio Pardi, "SIMONS human diversity project"

Résumé

The SIMONS project completed the 1000 human project by sequencing many
ancestral Asian and Oceania populations. Their results highlights the complexity
of ancestral Homo sapiens cross-breeding which occured at different times
and different continents (sapiens, neanderthalis and denisova).
A nice example of coalescence models application will be discussed.

Benjamin Linard, "Science and social networking"

Résumé

Social networks are more and more used by scientists to spread
their research (Twitter, LinkedIn, Facebook). But social networks specifically
targeted to scientists are now appearing (Google scholar, Researchgate).
Are these useful and can be considered as a research tool ?
Or are they just a consequence of the "mediatic science" in which we live
more and more, forgetting sometimes the purposes of science ?
