The Internet has seen a proliferation of specialized middlebox devices that carry out crucial network functionality such as load balancing, packet inspection or intrusion detection, amongst others. Traditionally, high performance network devices have been built on custom multi-core, specialized memory hierarchies, architectures which are well suited to packet processing. Recently, commodity PC hardware has experienced a move to multiple multi-core chips, as well as the routine inclusion of multiple memory hierarchies in the so-called NUMA architectures. While a PC architecture is obviously not specifically targeted to network applications, it nevertheless provides high performance cheaply. Furthermore, a few commodity switch technologies have recently emerged offering the possibility to control the switching of flows in a rather fine grained manner. Put together, these new technologies offer a new network commodity platform enabling new flow processing and forwarding at an unprecedented flexibility and low cost. [less ▲]

In the Ardenne massif, floodplains have recorded fluctuations in the production of sediment and several periods of increased sediment deposition have been identified. Before the first deforestations rivers developed multiple channels in alluvial forests. Floodplains were not well-developed and probably very humid, which explains the presence of peat layers within the alluvial sequences. In the Amblève catchment, the first increased sedimentary deposition of the Holocene occurred during the Bronze Age (3200 BP), in relation to deforestation and the first crop cultures in the area. An organic deposition has occurred around 2700 BP and could correspond with a period of climatic degradation. Several peat layers have also been dated to around 1000 BP and probably indicate very low anthropogenic pressure. From the 11th Century onwards, there was an increase in sedimentation and a greater concentration of charcoal is present in the alluvial deposits. In many catchments there is an important increase in the sedimentation at the end of the 14th century, which can be related to the development of many iron factories. Analyses of slag concentration produced in these former factories allow us to reconstruct the evolution of the floodplain topography since the inception of the iron industries, in relation to the periods of activity. Total sedimentation in the smaller valleys since the initiation of iron industries amounts 0.5 to 1.0 m, which is in most cases about 50% of the total sediment present in the floodplains and corresponds to a mean sedimentation rate ranging between 10 and 20 cm/century. Such values are explained by various former agricultural practices and forest clearings associated with the huge demand for charcoal by the iron industry. About 20 ha of forest were cleared for the yearly consumption of a refining forge or a blast furnace and more than three hundred iron factories existed in the Ardenne Massif between the 14th and the 19th century.

Wolf software is a set of coupled numerical tools developed for almost ten years for simulating a wide range of free surface flows and transport phenomena. In the scope of new applications in hydraulic structure design and fluid-structure interaction, additional developments have been implemented in the finite volume 2D model to deal with boundaries not aligned along axis or with moving structures. The cut cell based approach, simpler than other classical methods, is based on the division with a sub-grid of the initial Cartesian meshes. While keeping the advantages of regular grids in terms of simplicity, accuracy and storage capacity, it enables to compute instantaneous effects of a structure movement on the fluid or to deal with complex boundaries inclined compared to mesh axis. Several test cases are presented, as well as an applica-tion of the enhanced model, coupled with a 1D one, to the computation of the hydrodynamic fields induced by a lock-door movement. [less ▲]

Plant diseases represent a growing threat to the global food supply. The factors contributing to pathogen transmission from plant to plant remain poorly understood. Statistical correlations between rainfalls and plant disease out- breaks were reported; however, the detailed mechanisms linking the two were relegated to a black box. In this combined experimental and theoretical study, we focus on the impact dynamics of raindrops on infected leaves, one drop at a time. We find that the deposition range of most of the pathogen-bear- ing droplets is constrained by a hydrodynamical condition and we quantify the effect of leaf size and compliance on such constraint. Moreover, we identify and characterize two dominant fluid fragmentation scenarios as responsible for the dispersal of most pathogen-bearing droplets emitted from infected leaves: (i) the crescent-moon ejection is driven by the direct interaction between the impacting raindrop and the contaminated sessile drop and (ii) the inertial detachment is driven by the motion imparted to the leaf by the raindrop, lead- ing to catapult-like droplet ejections. We find that at first, decreasing leaf size or increasing compliance reduces the range of pathogen-bearing droplets and the subsequent epidemic onset efficiency. However, this conclusion only applies for the crescent moon ejection. Above a certain compliance threshold a more effective mechanism of contaminated fluid ejection, the inertial detachment, emerges. This compliance threshold is determined by the ratio between the leaf velocity and the characteristic velocity of fluid fragmentation. The inertial detachment mechanism enhances the range of deposition of the larger con- taminated droplets and suggests a change in epidemic onset pattern and a more efficient potential of infection of neighbouring plants. Dimensionless parameters and scaling laws are provided to rationalize our observations. Our results link for the first time the mechanical properties of foliage with the onset dynamics of foliar epidemics through the lens of fluid fragmentation. We discuss how the reported findings can inform the design of mitigation strategies acting at the early stage of a foliar disease outbreak. [less ▲]

Antibubbles have been produced and studied with the help of a high-speed camera. An antibubble is defined as a fluid object constituted by a thin air shell surrounding a liquid and surrounded by the same liquid. Images reveal some key physical processes and fluid instabilities which take place when an antibubble forms and dies. The collapsing speed of the air film has been measured. Culik's theory does not apply. A new mechanism has been introduced. [less ▲]

Fluid management and assessment of organ perfusion in organ donors with hypotonic polyuria remain poorly investigated problems. In our protocol, urinary losses (565 +/- 202 ml/h) were replaced volume for volume by 3.3% dextrose/0.3% natrium chloride solution (Baxter) with 20 mmol/l potassium chloride. Concentrated red blood cells were administered to maintain hematocrit at about 30%, and volume expansion (central venous pressure above 6 mmHg) was obtained by gelatin (haemaccel) infusion. In all donors (n = 9), plasma electrolytes remained within normal limits despite hypotonic polyuria. Suppression of initial plasma renin activity (PRA: 9.7 +/- 3.6 ng/ml per hour) was obtained by subacute volume expansion. In eight donors the hemodynamic status improved, dopamine administration, when used, was discontinued, and PRA decreased (2.3 +/- 0.7 ng/ml per hour; P less than 0.05). The only donor who failed to respond to fluid therapy had increased PRA (24.2 ng/ml per hour). During fluid challenge, an inverse relationship was demonstrated between mean arterial pressure and PRA in all nine donors (r = -0.61; P less than 0.001), while there were no significant changes in blood urea. creatinine, or urine output. It is concluded that in organ donors, proper maintenance of the hemodynamic status and suppression of the renin stress response may be obtained by an adequate fluid management, involving both qualitative restoration and expansion of intravascular volume.
