Rupture dynamique des failles non-planaires en différences finies

Ce travail est divisé en deux parties: la première est consacrée à la propagation des ondes et la seconde à la rupture dynamique des séismes. Dans la première partie je propose une révision des concepts de base des méthodes en différences finies (DF). Un accent particulier est fait sur la méthode choisie en DF, basée sur une grille partiellement en quinconce (GPQ), utilisée dans la deuxième partie du travail pour étudier la rupture des séismes. Les conditions aux limites sur la surface libre ainsi qu'à l'intérieur d'une fracture plane sont traitées, en discutant certaines approches déjà établies dans chaque cas. La formulation et la mise au point des conditions de radiation " Perfectly Matched Layer " (PML) sont abordées en trois dimensions (3D). Des tests d'absorption sont ainsi présentés en milieux de propagation homogènes et hétérogènes. Dans la deuxième partie, je propose premièrement une autre révision, cette fois-ci sur la mécanique de la rupture. Une fois ainsi posé le problème central de ce travail, j'aborde la modélisation numérique de la rupture dynamique de failles non-planaires en deux dimensions (2D). Une nouvelle approche en DF permettant de résoudre ce problème complexe est donc introduite. Une loi d'échelle, reliant le pas de discrétisation et le nombre de points à l'intérieur de la source, permet d'augmenter la précision des solutions en réduisant les oscillations numériques. Le passage à la géométrie 3D est fait. Sa précision et sa convergence sont analysées en termes de la résolution de la zone de cohésion. La méthode est validée dans le cas de ruptures spontanées planes et non-planaires (i.e. curvilignes) grâce à la comparaison des résultats avec ceux obtenus par d'autres méthodes numériques indépendantes. Finalement, la méthode est appliquée le long de failles non-planaires sous l'effet d'une charge tectonique biaxiale. La géométrie de la faille s'est avérée un facteur déterminant dans la propagation de la rupture. L'analyse de la rupture du séisme de Landers (1992) illustre ce fait, où des simulations faites en tenant compte de la vraie géométrie du séisme sont fondamentalement différentes de celles réalisées par d'autres auteurs où la faille a été considérée comme plane.This work is separated into two parts: the first part is devoted to wave propagation, and the second part treats the dynamic rupture of earthquakes. In the first part I propose a general review of the basic concepts concerning finite difference (FD) methods. Based on a partly staggered grid, the FD technique used in the second part of the work to study the rupture of earthquakes is analyzed in detail. The free surface and the planar crack boundary conditions are treated in separated sections. Several approaches, previously introduced by different authors, are discussed for each problem. The formulation and implementation of the Perfectly Matched Layer (PML) absorbing boundary conditions in three dimensions (3D) are described. Different tests to illustrate the performance of these boundary conditions are presented in homogeneous and heterogeneous media. In the second part I firstly provide an overview of rupture mechanics. After formulating the main problem of this study, I tackle the numerical modeling of nonplanar faults in two dimensions (2D). A new approach allowing these kinds of complex simulations is then introduced. A scaling law, relating the grid size to the amount of grid points discretizing the source, allows an increase in the precision of solutions by reducing the numerical oscillations. The extension of the rupture model to 3D is performed. Both numerical precision and convergence are analyzed in terms of the cohesive zone resolution. The model is validated for the spontaneous rupture along planar and nonplanar (i.e. curvilinear) faults by comparing solutions with those yielded by two independent numerical approaches. Finally, the method is applied to the case of nonplanar faults loaded in a biaxial tectonic stress regime. The fault geometry becomes an extremely important factor for rupture propagation under these conditions. A dynamic rupture analysis of the 1992 Landers earthquake confirms the importance of the fault geometry, since fundamentally different results are obtained when considering the real rupture surface with respect to those reported by previous authors where the fault was assumed to be planar.NICE-BU Sciences (060882101) / SudocSudocFranceF

A Suite of Exercises for Verifying Dynamic Earthquake Rupture Codes

The article of record as published may be found at http://dx.doi.org/10.1785/0220170222We describe a set of benchmark exercises that are designed to test if computer codes that simulate dynamic earthquake rupture are working as intended. These types of computer codes are often used to understand how earthquakes operate, and they produce simulation results that include earthquake size, amounts of fault slip, and the patterns of ground shaking and crustal deformation. The benchmark exercises examine a range of features that scientists incorporate in their dynamic earthquake rupture simulations. These include implementations of simple or complex fault geometry, off-fault rock response to an earthquake, stress conditions, and a variety of formulations for fault friction. Many of the benchmarks were designed to investigate scientific problems at the forefronts of earthquake physics and strong ground motions research. The exercises are freely available on our website for use by the scientific community.Southern California Earthquake Center (SCEC

Considerations and consequences of allowing DNA sequence data as types of fungal taxa

Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity). Two proposals to amend the International Code of Nomenclature for algae, fungi, and plants (ICN), allowing DNA sequences alone (of any region and extent) to serve as types of taxon names for voucherless fungi (mainly putative taxa from environmental DNA sequences), have been submitted to be voted on at the 11th International Mycological Congress (Puerto Rico, July 2018). We consider various genetic processes affecting the distribution of alleles among taxa and find that alleles may not consistently and uniquely represent the species within which they are contained. Should the proposals be accepted, the meaning of nomenclatural types would change in a fundamental way from physical objects as sources of data to the data themselves. Such changes are conducive to irreproducible science, the potential typification on artefactual data, and massive creation of names with low information content, ultimately causing nomenclatural instability and unnecessary work for future researchers that would stall future explorations of fungal diversity. We conclude that the acceptance of DNA sequences alone as types of names of taxa, under the terms used in the current proposals, is unnecessary and would not solve the problem of naming putative taxa known only from DNA sequences in a scientifically defensible way. As an alternative, we highlight the use of formulas for naming putative taxa (candidate taxa) that do not require any modification of the ICN.Peer reviewe

Stoma-free survival after anastomotic leak following rectal cancer resection: worldwide cohort of 2470 patients

Background: The optimal treatment of anastomotic leak after rectal cancer resection is unclear. This worldwide cohort study aimed to provide an overview of four treatment strategies applied. Methods: Patients from 216 centres and 45 countries with anastomotic leak after rectal cancer resection between 2014 and 2018 were included. Treatment was categorized as salvage surgery, faecal diversion with passive or active (vacuum) drainage, and no primary/secondary faecal diversion. The primary outcome was 1-year stoma-free survival. In addition, passive and active drainage were compared using propensity score matching (2: 1). Results: Of 2470 evaluable patients, 388 (16.0 per cent) underwent salvage surgery, 1524 (62.0 per cent) passive drainage, 278 (11.0 per cent) active drainage, and 280 (11.0 per cent) had no faecal diversion. One-year stoma-free survival rates were 13.7, 48.3, 48.2, and 65.4 per cent respectively. Propensity score matching resulted in 556 patients with passive and 278 with active drainage. There was no statistically significant difference between these groups in 1-year stoma-free survival (OR 0.95, 95 per cent c.i. 0.66 to 1.33), with a risk difference of -1.1 (95 per cent c.i. -9.0 to 7.0) per cent. After active drainage, more patients required secondary salvage surgery (OR 2.32, 1.49 to 3.59), prolonged hospital admission (an additional 6 (95 per cent c.i. 2 to 10) days), and ICU admission (OR 1.41, 1.02 to 1.94). Mean duration of leak healing did not differ significantly (an additional 12 (-28 to 52) days). Conclusion: Primary salvage surgery or omission of faecal diversion likely correspond to the most severe and least severe leaks respectively. In patients with diverted leaks, stoma-free survival did not differ statistically between passive and active drainage, although the increased risk of secondary salvage surgery and ICU admission suggests residual confounding

Stoma-free Survival After Rectal Cancer Resection With Anastomotic Leakage: Development and Validation of a Prediction Model in a Large International Cohort.

Objective:To develop and validate a prediction model (STOMA score) for 1-year stoma-free survival in patients with rectal cancer (RC) with anastomotic leakage (AL).Background:AL after RC resection often results in a permanent stoma.Methods:This international retrospective cohort study (TENTACLE-Rectum) encompassed 216 participating centres and included patients who developed AL after RC surgery between 2014 and 2018. Clinically relevant predictors for 1-year stoma-free survival were included in uni and multivariable logistic regression models. The STOMA score was developed and internally validated in a cohort of patients operated between 2014 and 2017, with subsequent temporal validation in a 2018 cohort. The discriminative power and calibration of the models' performance were evaluated.Results:This study included 2499 patients with AL, 1954 in the development cohort and 545 in the validation cohort. Baseline characteristics were comparable. One-year stoma-free survival was 45.0% in the development cohort and 43.7% in the validation cohort. The following predictors were included in the STOMA score: sex, age, American Society of Anestesiologist classification, body mass index, clinical M-disease, neoadjuvant therapy, abdominal and transanal approach, primary defunctioning stoma, multivisceral resection, clinical setting in which AL was diagnosed, postoperative day of AL diagnosis, abdominal contamination, anastomotic defect circumference, bowel wall ischemia, anastomotic fistula, retraction, and reactivation leakage. The STOMA score showed good discrimination and calibration (c-index: 0.71, 95% CI: 0.66-0.76).Conclusions:The STOMA score consists of 18 clinically relevant factors and estimates the individual risk for 1-year stoma-free survival in patients with AL after RC surgery, which may improve patient counseling and give guidance when analyzing the efficacy of different treatment strategies in future studies
