Les processeurs multi-coeurs sur PC, en même temps que les progrès récents sur la performance de la mémoire et des bus, suggèrent un candidat idéal pour la construction d’architectures de routeurs purement logicielles qui soient flexibles et en même temps performantes. Dans cet article, nous présentons une architecture de commutation de paquets pour les routeurs logiciels ou virtuels dont l’objectif principal est de prévenir des accès mémoire coûteux tout en utilisant les ressources CPU disponibles au mieux pour traiter et commuter les paquets. Nous présentons premièrement le principe d’arbre de commutation dont la fonction est de garder les paquets commutés dans la même hiérarchie de cache du processeur. Nous identifions ensuite la source de contention principale des performances de commutation comme l’accès concurrent aux interfaces de sorties puis analysons les gains potentiels de performance en utilisant un verrou sur les interfaces de sortie ainsi qu’un mécanisme de retour sur l’état des queues du routeur. Finalement, nous proposons et évaluons une modification des arbres de commutation qui permet de contourner la contention due au partage des interfaces de sortie par les arbres [less ▲]

We estimate investable comoment equity risk premiums for the US markets. The stock's contribution to the asymmetry and the fat tails of the market portfolio's payoff are priced into a coskewness premium and a cokurtosis premium. We construct zero-investment strategies that are long and short in coskewness and cokurtosis equity risks; we infer from the spread the returns attached to a unit exposure to US equity coskewness and cokurtosis. The coskewness and cokurtosis premiums present positive monthly average returns of 0.27% and 0.14% from January 1959 to December 2011. Comoment risks appear to be significantly priced within the US stock market and display significant explanatory power regarding the US size and book-to-market effects. The premiums do not subsume, but rather complement the empirical capital asset pricing model. Our analysis relies on data collected from CRSP (Chicago Research Center for Security Prices) over December 1955 to December 2011. To our knowledge, the paper is the first to propose investable higher-moment risk factors over such an extensive time period. [less ▲]

Psoriasis is a common chronic inflammatory dermatitis mediated by cytokines released by dendritic plasmacytoid cells in combination with Th1- and Th17-cells. This complex and multifactorial condition is commonly associated with some comorbidities. The complexity of a coordinated management of such intricated pathologies is obvious. It calls for the so-called medicine "centered around the patient" which tops off the evidence-based medicine. Vitamin D by its immunomodulatory effect on T helper cells exerts a therapeutic benefit on psoriasis and some of its comorbidities including the metabolic syndrome. A vitamin D oral treatment was proposed in order to reduce the cardiovascular risk, and the ensuing morbidity and mortality. [less ▲]

PURPOSE: Retrospective studies have shown similar survival among patients with acute myeloid leukemia (AML) and myelodysplasia (MDS) after nonmyeloablative compared with myeloablative conditioning. Refined risk stratification is required to design prospective trials. PATIENTS AND METHODS: We stratified outcomes among patients with AML (n = 391) or MDS (n = 186) who received either nonmyeloablative (n = 125) or myeloablative (n = 452) allogeneic hematopoietic cell transplantation (HCT) based on comorbidities, as assessed by a HCT-specific comorbidity index (HCT-CI), as well as disease status. Patients receiving nonmyeloablative conditioning were older, more frequently pretreated, more often received unrelated grafts, and more often had HCT-CI scores of 3 compared with patients who received myeloablative conditioning. RESULTS: Patients with HCT-CI scores of 0 to 2 and either low or high disease risks had probabilities of overall survival at 2 years of 70% and 57% after nonmyeloablative conditioning compared with 78% and 50% after myeloablative conditioning, respectively. Patients with HCT-CI scores of 3 and either low or high disease risks had probabilities of overall survival of 41% and 29% with nonmyeloablative conditioning compared with 45% and 24% with myeloablative regimens, respectively. After adjusting for pretransplantation differences, stratified outcomes were not significantly different among patients receiving nonmyeloablative compared with myeloablative conditioning, with the exception of lessened nonrelapse mortality (hazard ratio, 0.50; P = .05) in the highest risk group. CONCLUSION: Patients with low comorbidity scores could be candidates for prospective randomized trials comparing nonmyeloablative and myeloablative conditioning regardless of disease status. Additional data are required for patients with low-risk diseases and high comorbidity scores. Novel antitumor agents combined with nonmyeloablative HCT should be explored among patients with high comorbidity scores and advanced disease. [less ▲]
