Rubber bushings are extensively-used linking parts in a vehicle chassis that allow to filter noise and vibration. They influence much, however, the transient behaviour of the vehicle, such as its steering performance. Therefore building a multibody simulation with a relevant description of the rubber bushings is useful to describe the significant characteristics of the vehicle’s steering behavi...

In Salmonella, the rod substructure of the flagellum is a periplasmic driveshaft that couples the torque generated by the basal body motor to the extracellular hook and filament. The rod subunits self-assemble, spanning the periplasmic space and stopping at the outer membrane when a mature length of ~22 nm is reached. Assembly of the extracellular hook and filament follow rod completion. Hook i...

We evaluate the effects of state policy design features on SCHIP take-up rates and on the degree to which SCHIP benefits crowd out private benefits. The results indicate overall program take-up rates of approximately 10 percent. However, there is considerable heterogeneity across states, suggesting a potential role of inter-state variation in policy design. We find that several design mechanism...

In 1971, 44 percent of workers who had been currently entitled to social security disability insurance (DI) benefits for 1 year or more also received benefits from at least one other source. Their average disability insurance benefit was higher than that of persons who received only DI benefits. On the average, total benefits to those receiving multiple benefits were double the amounts paid to ...

BACKGROUND Disease has become one of the key causes of falling into poverty in rural China. The poor households are even more likely to suffer. The New Cooperative Medical Scheme (NCMS) has been implemented to provide rural residents financial protection against health risks. This study aims to assess the effect of the NCMS on alleviating health payment-induced poverty in the Shaanxi Province o...

Understanding how sterile worker castes in social insects first evolved is one of the supreme puzzles in social evolution. Here, we show that in the bee tribe Allodapini, the earliest societies did not entail a foraging worker caste, but instead comprised females sharing a nest with supersedure of dominance. Subordinates delayed foraging until they became reproductively active, whereupon they p...

cet article a pour objectif de montrer que le traducteur outre ses connaissances linguistiques et culturelles a besoin de moyens extérieurs ou d’instruments pour résoudre les problèmes de la traduction. nous allons commencer par les désigner et ensuite étudier les qualités et les défauts de chaque outil. pour cela nous ferons une comparaison entre le dictionnaire unilingue et bilingue. par la s...

This report presents the benefits of using the Model Driven Engineering (MDE) methodology to solve major difficulties encountered by usual high level synthesis (HLS) flows. These advantages are highlighted in a design space exploration environment we propose. MDE is the skeleton of our HLS flow dedicated to intensive signal processing to demonstrate the expected benefits of these software techn...
