Simulating a power system with both transmission and distribution networks modeled in detail is a huge computational challenge. In this paper, a Schur-complement-based domain decomposition algorithm is proposed to provide accurate, detailed dynamic simulations of such systems. The simulation procedure is accelerated with the use of parallel programming techniques, taking advantage of the parallelization opportunities inherent to domain decomposition algorithms. The proposed algorithm is general, portable and scalable on inexpensive, shared-memory, multi-core machines. A large-scale test system is used for its performance evaluation. [less ▲]

Novarina entretient avec la philosophie une relation faite d’attraction et de défiance. Le primat accordé à la parole et le refus de toute ontologie le conduisent à définir un nouveau modèle théorique, celui de la « fugue » et, tout en poursuivant le dialogue avec les philosophes, à construire ce que nous appellerons une dialectique de l’inattendu, mouvement par lequel le vide actif qui habite la personne humaine nourrit le renouvellement de la pensée et de l’action.

À travers ce chapitre, nous proposons de réaliser l’étude de différents apports de la philosophie de Jean-Paul Sartre à la réflexion et la pratique de la psychopathologie. La « psychopathologie de l’homme en situation » qui s’esquisse repose sur la notion fondamentale de l’émotion ainsi que sur la possibilité de dépassement de cette situation. Ce moment fait jaillir une trame temporelle puisqu’il révèle à la fois l’histoire et la biographie du sujet, mais également son projet et dès lors les fulgurances de la liberté. Penser l’homme en situation, le savoir sorcier ou magicien (c’est-à-dire à la fois ému et émouvant) et parvenir à mobiliser sa narrativité sont des paris essentiels de l’œuvre de Sartre, que la psychopathologie, tant dans sa dimension théorique que pratique, ne peut ignorer.

Pneumocystis fungi represent a highly diversified biological group with numerous species, which display a strong host-specificity suggesting a long co-speciation process. In the present study, the presence and genetic diversity of Pneumocystis organisms was investigated in 203 lung samples from woodmice (Apodemus sylvaticus) collected on western continental Europe and Mediterranean islands. The presence of Pneumocystis DNA was assessed by nested PCR at both large and small mitochondrial subunit (mtLSU and mtSSU) rRNA loci. Direct sequencing of nested PCR products demonstrated a very high variability among woodmouse-derived Pneumocystis organisms with a total number of 30 distinct combined mtLSU and mtSSU sequence types. However, the genetic divergence among these sequence types was very low (up to 3.87%) and the presence of several Pneumocystis species within Apodemus sylvaticus was considered unlikely. The analysis of the genetic structure of woodmouse-derived Pneumocystis revealed two distinct groups. The first one comprised Pneumocystis from woodmice collected in continental Spain, France and Balearic islands. The second one included Pneumocystis from woodmice collected in continental Italy, Corsica and Sicily. These two genetic groups were in accordance with the two lineages currently described within the host species Apodemus sylvaticus. Pneumocystis organisms are emerging as powerful tools for phylogeographic studies in mammals [less ▲]

Background. The prognosis of myelodysplastic syndromes (MDS) after allogeneic stem cell transplantation is critically determined by cytogenetic abnormalities, as previously defined by International Prognostic Scoring System (IPSS) cytogenetics. It has been shown that a new cytogenetic classification, included in the IPSS-R (cytogenetic-IPSS-R [C-IPSS-R]), can better predict the outcome of untreated MDS patients.Methods. In this study, we assessed the impact of the IPSS-R cytogenetic score (C-IPSS-R) on the outcome of 367 MDS patients transplanted from HLA-identical siblings or HLA allele-matched unrelated donors. Results. According to the C-IPSS-R, 178 patients (48%) fell in the good risk, 102 (28%) in the intermediate risk, 77 (21%) in the poor risk, and 10 (3%) in the very poor risk group. In multivariate analysis, after a median follow-up of 4 years, the poor and very poor-risk categories correlated with shorter overall survival (OS) (4-year OS, 32%; hazard ratio [HR], 1.59; P = 0.009 and OS, 10%; HR, 3.18; P = 0.002, respectively) and higher cumulative incidence of relapse (CIR) (CIR, 52%; HR, 1.82; P = 0.004 and CIR, 60%; HR, 2.44; P = 0.060, respectively). Conclusions. Overall, the C-IPSS-R changed the IPSS cytogenetic risk only in 8% of cases but identified a new risk group, the very poor C-IPSS-R category, with dismal outcome after allogeneic stem cell transplantation (10% 4-year OS, 60% 4-year CIR). Posttransplantation maintenance therapy should be investigated in prospective trials for patients with high-risk C-IPSS-R karyotypes. [less ▲]

Ce texte entend réévaluer l'idée de "pure synthèse intellectuelle" que l'on trouve chez Kant. Celle-ci cadre avec la pratique mathématique et métamathématique postérieure à Kant. Elle permet de dépasser l'alternative entre l'intuitionnisme développé dans la Critique de la raison pure et la fondation de la mathématique sur une logique formelle analytique. Je montre que cette idée convient à Bolzano et à Dedekind, dont je soutiens que les projets sont irréductibles à du logicisme et qui sont dès lors bien plus "kantiens" qu'il n'y paraît. [less ▲]

In this paper, the overvoltage problems that might arise from the integration of photovoltaic panels into low-voltage distribution networks is addressed. A distributed scheme is proposed that adjusts the reactive and active power output of inverters to prevent or alleviate such problems. The proposed scheme is model-free and makes use of limited communication between the controllers, in the form of a distress signal, only during emergency conditions. It prioritizes the use of reactive power, while active power curtailment is performed only as a last resort. The behavior of the scheme is studied using dynamic simulations on a single low-voltage feeder and on a larger network composed of 14 low-voltage feeders. Its performance is compared to a centralized scheme based on the solution of an Optimal Power Flow problem, whose objective function is to minimize the active power curtailment. The proposed scheme successfully mitigates overvoltage situations due to high photovoltaic penetration and performs almost as well as the Optimal Power Flow based solution with significantly less information and communication requirements.
