Situation et représentation dans l'œuvre de François Bon
No full textNé en 1953, François Bon publie son premier livre, Sortie d'usine, en 1982. Étudier ses textes, c'est se consacrer à une œuvre qui donne une place éminente à une nouvelle confrontation avec le réel. Sans oublier « l'ère du soupçon » qu'a représenté le nouveau roman ni l'apport immense des « années théoriques », ses textes ne cessent de renouveler la manière dont la littérature réinvestit l'écart qui existe entre le réel et sa représentation, entre le monde et la langue, en assumant la rupture qui les sépare, mais sans conclure à l'impossibilité totale de nouer des liens, de construire des ponts, fussent-ils secrets ou fragiles. Les trois textes qui font l'objet de ce travail, Calvaire des chiens (1990), Temps machine (1993) et Paysage fer (1999), ont été choisis parce qu'ils constituent autant de manières dont la littérature peut aujourd'hui construire le rapport entre le réel et sa représentation et parce qu'ils sont des jalons majeurs dans l'œuvre de François Bon

Mean Turbulence Statistics from Direct Numerical Simulations of Stably Stratified Channel Flows with One- and Two-Dimensional Surface Temperature Heterogeneity
No full textThe dataset contains a suite of Direct Numerical Simulation (DNS) results of pressure driven stably stratified channel flows, both with homogeneous and heterogeneous surface temperatures. The one-dimensional temperature heterogeneity is organized in streamwise infinite strips of width λy/2 with spanwise varying surface temperature with difference Δ θ, while the same temperature difference is maintained between the lower and upper wall to enforce overall stable stratification. In the cases with two-dimensional surface heterogeneity, the strips have a finite streamwise length λx/2.
Two different Reynolds numbers, i.e. Reτ=180 and Reτ=550, and two different Richardson numbers Riτ=120 and Riτ=960 are considered for the heterogeneous cases. For reference, a number of canonical stable channel flow cases with homogeneous surfaces at different Reynolds and Richardson numbers is also included. The simulations were run until a statistically steady state was reached, after which turbulence statistics were collected over a certain time window (30 h/uτ in most cases, see 'T_av' column in StableChannel_Overview.csv. ).
The dataset is generated with the SP-Wind code, an in-house DNS/LES code developed at KU Leuven. For details of the code structure and simulation set-up we refer to Bon and Meyers (2022) and Bon et al. (2023). We note that both publications also contain a schematic illustration of the surface heterogeneity configurations (Figure 1 there).
The dataset is organized as follows. A total of 46 simulations is included, and each has a separate folder. Each folder contains global simulation properties in flowproperties.csv, and horizontally-averaged profiles of relevant variables in profiles_cc.csv (variables on cell-centered grid) and profiles_st.csv (vertical derivatives on staggered grid). Besides, the folders of the streamwise homogeneous cases (kx = 0) contain streamwise-averaged yz-planes of velocity components, potential temperature, Reynolds stresses and temperature fluxes. For the cases with two-dimensional heterogeneity (kx > 0), phase-averaged 3D fields of these variables are included. Note that all variables are time-averaged. An overview of the mean flow properties of each simulation is provided in the file StableChannel_Overview.csv, which also includes relevant input parameters such as domain size and grid resolution.
Fore more information, we refer to the readme.txt file located in the dataset and to the two related publications.

Inventory and new records of Polychaete species from the Cap Bon peninsula , North East coast of Tunisia, Western Mediterranean Sea
No full textAn inventory of polychaete species is presented from the north-east coast of Tunisia with an historic review of the previous literature from Tunisian coasts. Altogether 40 families, 146 genera, and 238 species are currently known from the area, of which 86 taxa, 4 families (Chrysopetalidae, Pilargidae, Protodrilidae and Saccocirridae) and 40 genera (Saccocirrus, Protodrilus, Parathelepus, Thelepus, Petta, Isolda, Brada, Tharyx, Paraprionospio, Jasmineira, Hypsicomus, Euchone, Pseudobranchiomma, Laonome, Galathowenia, Lugia, Pseudomystides, Protomystides, Pirakia, Mysta, Eurysyllis, Parapionosyllis, Streptosyllis, Paraehlersia, Sigambra,
Ancistrosyllis, Kefersteinia, Chrysopetalum, Bhawania, Fimbriosthenelais, Subadyte, Panthalis, Dorvillea, Scalibregma, Paradoneis, Cirrophorus, Metasychis, Websterinereis, Euniphysa and Mastobranchus) are new additions to the polychaete fauna of Tunisia. The list, which provides a synthesis of the regional taxonomic work, including coastal areas from Sidi Daoud to the area of Menzel Hurr (Cap Bon Peninsula, Western Mediterranean Sea), can serve as a baseline for future studies

MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
