Genome-wide screens are a powerful technique to dissect the complex network of genes regulating diverse cellular phenotypes. The recent adaptation of the CRISPR-Cas9 system for genome engineering has revolutionized functional genomic screening. Here, we present protocols used to introduce Cas9 into human lymphoma cell lines, produce high-titer lentivirus of a genome-wide sgRNA library, transduce and culture cells during the screen, isolate genomic DNA, and prepare a custom library for next-generation sequencing. These protocols were tailored for loss-of-function CRISPR screens in human lymphoma cell lines but are highly amenable for other experimental purposes.

International audience; This chapter provides a critical analysis of the evidence for technical activity specialization in the European Upper Paleolithic by sex. It reviews the arguments based on the kind of evidence researchers are likely to collect (e.g., direct, indirect, and analogical). Some hypotheses are based on suppositions generated by ethnographic comparisons, while others rely on direct or indirect indices (task diversification, activity zone locations, skill level identification, diversity of grave goods, and body evidence like handprints and skeletons). The aim of this chapter is to show that there was a reasoned distribution of activities within groups, accompanied by an emerging social hierarchy, but that it is very difficult to account exactly for what women and men did. And even if we suspect that some tasks were respectively performed by males or females, it is possible that there was also a certain amount of technical specialization that was not related to gender.

International audience; This chapter introduces several state of the art techniques that could help to make deep underwater archaeological photogrammetric surveys easier, faster, more accurate, and to provide more visually appealing representations in 2D and 3D for both experts and public. We detail how the 3D captured data is analysed and then represented using ontologies, and how this facilitates interdisciplinary interpretation and cooperation. Towards more automation, we present a new method that adopts a deep learning approach for the detection and the recognition of objects of interest, amphorae for example. In order to provide more readable, direct and clearer illustrations, we describe several techniques that generate different styles of sketches out of orthophotos developed using neural networks. In the same direction, we present the Non-Photorealistic Rendering (NPR) technique, which converts a 3D model into a more readable 2D representation that is more useful to communicate and simplifies the identification of objects of interest. Regarding public dissemination, we demonstrate how recent advances in virtual reality to provide an accurate, high resolution, amusing and appropriate visualization tool that offers the public the possibility to ‘visit’ an unreachable archaeological site. Finally, we conclude by introducing the plenoptic approach, a new promising technology that can change the future of the photogrammetry by making it easier and less time consuming and that allows a user to create a 3D model using only one camera shot. Here, we introduce the concepts, the developing process, and some results, which we obtained with underwater imaging.

This chapter examines Leibniz’s complex relations to Descartes. These relations are deeply influenced by the evolution of the intellectual context from the beginning of the 1670s to the early eighteenth century. Beyond Leibniz’s overall appraisal of Descartes’s philosophy, there are three areas that stand out in which the discussion and criticism of Descartes’s ideas played a decisive role in the development of Leibniz’s thought: epistemology, natural philosophy, and philosophy of mind. There are three central issues at stake between the two philosophers: the nature and role of evidence, the use of final causes, and the Law of Continuity.

Multiple theories of working memory are described in the chapters of this book and often these theories are viewed as being mutually incompatible, yet each is associated with a supporting body of empirical evidence. This chapter argues that many of these differences reflect different research questions, different levels of explanation, and differences in how participants perform their assigned tasks in different laboratories, rather than fundamental theoretical adversity. It describes a version of a multiple component working memory in which a range of specialized cognitive functions (or mental tools) act in concert, giving the impression, at a different level of explanation, of a unified cognitive system. The chapter argues that more rapid and more substantial scientific progress on the understanding of the concept of working memory would be achieved through identifying the levels of explanation explored within each theoretical framework, and attempting to integrate theoretical frameworks rather than perpetuating debate with no clear resolution in sight.

International audience; The threat of quantum computers has sparked the development of a new kind of cryptography to resist their attacks. Isogenies between elliptic curves are one of the tools used for such cryptosystems. They are championed by SIKE (Supersingular isogeny key encapsulation), an "alternate candidate" of the third round of the NIST Post-Quantum Cryptography Standardization Process. While all candidates are believed to be mathematically secure, their implementations may be vulnerable to hardware attacks. In this work we investigate for the first time whether Ti's 2017 theoretical fault injection attack is exploitable in practice. We also examine suitable countermeasures. We manage to recover the secret thanks to electromagnetic fault injection on an ARM Cortex A53 using a correct and an altered public key generation. Moreover we propose a suitable countermeasure to detect faults that has a low overhead as it takes advantage of a redundancy already present in SIKE implementations.

International audience; This introductory chapter gives an overview of the aims, scope, and approach of the volume, while also providing a thematic bibliography of the most significant previous literature on Arabic and contact-induced change.

Part 3: Innovation and Entrepreneurship; International audience; Digitalization of research processes, like those related to open science, for example, has had mixed outcomes for the visibility of African scholarship. One reason for this may be that ICT-based interventions aimed at improving African research systems presume a country deficit model, that is, a view that Africa’s research environment is inherently under-resourced, and failing. Our study set out to explore, through a collaborative rich picture exercise, how research practices are viewed in Rwanda in the light of digitalization by a mixed group of global North and South information specialists. Through an in-depth qualitative inductive analysis of the participants’ accounts, we uncovered not only a dominant discourse of “deficit”, but also an underlying but hidden counter-narrative of resistance to this. We extrapolate how this view could be seen as having the potential for more optimistic outcomes in promoting a more inclusive African research paradigm. We then suggest a research agenda to explore the potential for the digitalization of research processes to provide a means of enabling a dialogue between Western and indigenous forms of knowledge.

Automata networks are mappings of the form \(f: Q^Z \rightarrow Q^Z\), where Q is a finite alphabet and Z is a set of entities; they generalise Cellular Automata and Boolean networks. An update schedule dictates when each entity updates its state according to its local function \(f_i: Q^Z \rightarrow Q\). One major question is to study the behaviour of a given automata networks under different update schedules. In this paper, we study automata networks that are invariant under many different update schedules. This gives rise to two definitions, locally commutative and globally commutative networks. We investigate the relation between commutativity and different forms of locality of update functions; one main conclusion is that globally commutative networks have strong dynamical properties, while locally commutative networks are much less constrained. We also give a complete classification of all globally commutative Boolean networks.
