  , 2019. Pelvic surgery raises the challenge of preser- vation of nerves that handle urinary, gen- ital and digestive functions, especially in situations where these structures may be modi- fied by tumors or malformations. Recent works on 3D nerve visualization, that rely on cadavers dissections [1, 3] or intra-operative use of probes detecting myelin-binding fluorophores [5], do not provide pre- or post-operative analysis of the pelvic nervous anatomy. Magnetic reso- nance neurography as in [12] requires a slice by slice manual segmentation of the nerves. Dif- fusion MRI, associated with tractography algo- rithms, is currently the only technique allow- ing for in-vivo exploration of the nervous net- work [2] with no need for manual nerve segmen- tation. In contrast to brain imaging that moti- vated a lot of work, only few studies focus on pe- ripheral nerves visualization [9, 10, 14]. In this paper, we propose a method for pelvic tractog- raphy analysis based on patient-specific organ segmentation. It is demonstrated with promis- ing results on a healthy adult subject.
• Following and Analyzing a Human Being: On the Continuity and Singularity of an Individual

  , 2019, pp.13-43. This chapter addresses three restrictions observed within the social sciences that prevent researchers from seeing human beings as such. It proposes an ontological argument in favor of following and analyzing human individuals. The chapter compares phenomenography with some phenomenological approaches in anthropology in order to insist on the methodological radicality of the former. As reflected in philosophy's classic debates, an anthropology that sets out to be anthropo-focused cannot separate an action, connection or experience from the person who performs and lives it. The chapter provides the methodological guidelines concerning, in particular, the possible ways of beginning a phenomenographic research which focuses on the rapper LK. It focuses on what calls a "videophenomenography", which corresponds to the moment where LK agreed to film himself, alone, during the creation of a verse. One particularly interesting device attempted was the realization of a "videophenomenography", in which LK agreed to film himself, alone, during a moment of creation.

  European Spine Journal, Springer Verlag, 2019, 28, pp.3026–3034. Purpose Measurement of vertebral axial rotation (VAR) is relevant for the assessment of scoliosis. Stokes method allows estimating VAR in frontal X-rays from the relative position of the pedicles and the vertebral body. This method requires identifying these landmarks for each vertebral level, which is time-consuming. In this work, a quasi-automated method for pedicle detection and VAR estimation was proposed. Method A total of 149 healthy and adolescent idiopathic scoliotic (AIS) subjects were included in this retrospective study. Their frontal X-rays were collected from multiple sites and manually annotated to identify the spinal midline and pedicle positions. Then, an automated pedicle detector was developed based on image analysis, machine learning and fast manual identification of a few landmarks. VARs were calculated using the Stokes method in a validation dataset of 11 healthy (age 6–33 years) and 46 AIS subjects (age 6–16 years, Cobb 10°–46°), both from detected pedicles and those manually annotated to compare them. Sensitivity of pedicle location to the manual inputs was quantified on 20 scoliotic subjects, using 10 perturbed versions of the manual inputs. Results Pedicles centers were localized with a precision of 84% and mean difference of 1.2 ± 1.2 mm, when comparing with manual identification. Comparison of VAR values between automated and manual pedicle localization yielded a signed difference of − 0.2 ± 3.4°. The uncertainty on pedicle location was smaller than 2 mm along each image axis. Conclusion The proposed method allowed calculating VAR values in frontal radiographs with minimal user intervention and robust quasi-automated pedicle localization. (10.1007/s00586-019-06158-z)

• An Turyn-based neural Leech decoder

  , 2019. A new decoder for the Leech lattice is presented. This quasi-optimal decoder utilizes a re-encoding paradigm, where candidates are obtained via a shallow neural network. This implies easy parallelization and low latency. The decoder exploits the fact that the Leech lattice is obtained from the direct sum of three polarized Gosset 8-dimensional lattices. This Turyn's construction was used in 2010 by G. Nebe to build the extremal even unimodular lattice in dimension 72 from three copies of the Leech lattice. Thus, we view this work as a first step towards the implementation of an efficient decoder for the Nebe 72-dimensional lattice.

• De la « fronde anti-Linky » à la justification écologique du smart metering : retour sur la genèse d’un projet controversé
  
  • Draetta Laura

  Lien social et Politiques, Anjou, Québec : Éd. Saint-Martin ; Rennes : Presses de l'EHESP, 2019 (82), pp.52. L’article propose une analyse de la controverse française sur le compteur communicant Linky en interrogeant la construction de sa justification écologique. Il défend l’hypothèse que cette controverse s’enracine de manière concomitante dans la critique du nouvel objet technique et dans celle de la genèse du projet politico-industriel qui a présidé à son déploiement national. Il combine analyse de la presse, étude documentaire et enquête de terrain pour restituer, en deux parties, une description de la controverse en France à partir de son traitement médiatique et une analyse de la genèse institutionnelle du projet Linky. La première partie montre une controverse publique et plurithématique en permanente recomposition, dans laquelle le dispositif technique s’expose à des épreuves successives, dont celle de la dénonciation d’une tentative de verdissement d’un projet de modernisation industrielle. La deuxième partie porte un regard réflexif sur le projet Linky et montre comment les oppositions qui le concernent se nourrissent des limites de son cadrage et de son accompagnement par les institutions politiques et administratives.

• Early Detection of User Engagement Breakdown in Spontaneous Human-Humanoid Interaction

  IEEE Transactions on Affective Computing, Institute of Electrical and Electronics Engineers, 2019. This paper presents a supervised classification system for forecasting a potential user engagement breakdown in human-robot interaction. We define engagement breakdown as a failure to successfully complete a predefined interaction scenario, where the user leaves before the expected end. The goal is thus to detect as early as possible such a potential engagement breakdown during the interaction between a human and a humanoid robot. To this end, we exploit a dataset that we have collected in real-world conditions where a set of participants were left to spontaneously engage in an interaction with the robot. The dataset is labeled according to the presence/absence of engagement breakdown. This study investigates the use of a multimodal approach to this problem, where a set of non-verbal features is considered to characterize the users' behavior. The use of combined multimodal features is found to effectively improve the performance of the system. The optimal set of data streams useful for this task is the combination of the distance to the robot, gaze and head motion, as well as facial expressions and speech. We study the time extent over which a user's departure can be anticipated. We find that this ability to anticipate the departure depends on the window during which we observe the user behavior.

  Designs, Codes and Cryptography, Springer Verlag, 2019, 87, pp.1447 - 1455. We construct trace codes over Z 4 based on Boolean functions and their support. The Lee weight distribution of these codes is studied by using the Walsh-Hadamard transform of the Boolean functions, and exponential character sums. We obtain few weights codes. In particular, bent and semi-bent functions give three-weight codes. (10.1007/s10623-018-0542-x)

• Distributed Approximate k-Core Decomposition and Min-Max Edge Orientation: Breaking the Diameter Barrier

  , 2019. We design distributed algorithms to compute approximate solutions for several related graph optimization problems. All our algorithms have round complexity being logarithmic in the number of nodes of the underlying graph and in particular independent of the graph diameter. By using a primal-dual approach, we develop a 2(1 +)-approximation algorithm for computing the coreness values of the nodes in the underlying graph, as well as a 2(1 +)-approximation algorithm for the min-max edge orientation problem, where the goal is to orient the edges so as to minimize the maximum weighted in-degree. We provide lower bounds showing that the aforementioned algorithms are tight both in terms of the approximation guarantee and the round complexity. Finally, motivated by the fact that the densest subset problem has an inherent dependency on the diameter of the graph, we study a weaker version that does not suffer from the same limitation.

  , 2019, pp.44-48. In 1990, W. Cellary and G. Jomier proposed the Database Version (DBV) approach, which allows to manage multiversion databases - those in which several versions of a set of data items coexist. Ever since, its model, theory and algorithms have been adopted in a multitude of research initiatives and publications, and have been applied to a variety of applications, in particular those in which there is a need for keeping track of parallel or (spatio)-temporal evolution of states of the world. This article presents an overview of the DBV approach, and some of the associated research initiatives throughout three decades, pointing out new potential directions. It has been written in tribute to Geneviève Jomier, Prof. Emeritus of The Université Paris-Dauphine, who left us in March 2018.
