Understanding processes of formation of accretionary wedges requires studying young and well preserved examples. The Lengguru wedge (West Papua) is younger than 10 Myr and is a result of oblique and fast subduction (11cm/yr) of the Bird’s Head (a part of the Australian margin beneath the Melanesian Arc). Thus, the rapid formation of this wedge (actually a Fold and Thrust Belt) may be attributed to a single tectonic event. High pressure (HP) metabasic and metasedimentary rocks have been discovered in the core of the wedge in the Wandamen peninsula. Locally, these rocks are overprinted by migmatization during the decompression. Field relationships indicate that migmatites and anatectic leucogranite crosscut the HP metamorphic rocks. This paper reports characterization of petrology and thermobarometry of metasediments and metabasic samples, all included in a former mélange-type rock association, as well as geochronology of metasediments. Pressure-Temperature (PT) conditions highlight two stages of metamorphism within a small time bracket. In metasediments, a first stage of relatively HP (~13-17 kbar) is observed as attested by a first paragenesis of garnet-kyanite-phengite. Garnet, kyanite and phengite are then destabilized in favor of biotite during the decompression (5-12 kbar and > 550°C). Late fractures filled with chlorite and a second generation of white mica crosscut the foliation (< 7 kbar and 500-600°C). In metabasic rocks, the peak of pressure is reached from 15 to 23 kbar and from 525 to 650°C. Geochronological study was conducted using U-Pb dating (LA-MC-ICPMS) on zircons from the metasedimentary and migmatitic rocks. Some zircon cores often present high Th/U ratio typical for magmatic origin, as confirmed by trace element signature of metasediments, and recorded ages older than 300 Ma, witness of the activity of a volcanic arc on the former margin of the Australian craton. Most others zircons presents a low Th/U ratio attesting their metamorphic origin, confirmed by inclusions of kyanite. The metamorphic zircons are dated between 5.61 ± 0.04 Ma and 8.1 ± 1.1 Ma. These very young metamorphic ages attest for a rapid subduction and exhumation event. [less ▲]

We study the problem of predicting Internet path changes and path performance using traceroute and machine-learning techniques. Path changes are frequently linked to path inflation and performance degradation. Therefore, predicting their occurrence could improve the analysis of path dynamics using traceroute. By relying on neural networks and using empirical distribution based input features, we show that we are able to predict (i) the remaining life time of a path before it actually changes, and (ii) the number of path changes in a certain time slot with relatively high accuracy. We also show that it is possible to predict path performance in terms of latency, opening the door to novel, machine-learning-based approaches for RTT prediction. [less ▲]

threo-Methylphenidate hydrochloride is the most widely prescribed drug to treat attention deficit hyperactivity disorder (ADHD). Herein we present the batch-to-flow translation of a carbene-based intramolecular strategy for the diastereoselective preparation of this active pharmaceutical ingredient. The process relies on the thermal generation and decomposition of a hazardous diazospecies, its thermal intramolecular C-H insertion reaction yielding an intermediate β-lactam, and its subsequent acidic methanolysis, giving enriched threo-methylphenidate hydrochloride in 70% isolated yield. The automated microfluidic setup telescopes 2 chemical transformations, 1 intermediate in-line purification and sustains a daily productivity of 20.4 g/day of methylphenidate hydrochloride. The preparation of the β-lactam is implemented on mesoscale in a pilot-scale continuous-flow reactor, providing 4.25 kg of this key intermediate per day. [less ▲]

Environmental inequality scholarship has sought to shed light on the unequal environmental conditions borne by poor people and racial minorities, and to challenge public policies. Most studies are concerned either with assessing the unequal distribution of environmental amenities and disamenities or with exploring the theoretical foundations of environmental justice movements. We propose an original approach to environmental inequality, focused not only on the unequal distribution of environmental burdens but also on two other types of factors: the capacity to mobilize and engage in community organizations on the one hand and the spatial dimension of environmental inequalities on the other. The evidence for this study is from an opinion survey carried out in 2012 with 1298 individuals. We use a two-step cluster analysis method to compute a classification system based on four categories of variables: socio-economic, environmental, spatial, and social capital. [less ▲]

Description of the subject. Water erosion is a particularly important issue, especially in the Mediterranean and semi-arid zone. This zone is characterized by irregular rainfall patterns, which have a considerable influence on soil loss. In mountainous areas, water erosion phenomena are accentuated by steep slopes and low ground cover. The dams draining these areas undergound siltation linked to significant erosion. The silting of the dams drastically limits their capacity and thus their operating life. When used for recharging aquifers, the resuspension of fine particles may accumulate in the recharge areas and reduce infiltration capacity by clogging soil porosity. This leads to a significant reduction of groundwater levels. Additionally, groundwater situated in the coastal zone is submitted to intensive pumping. These two phenomena make groundwater particularly sensitive to marine intrusions. Objectives. This article aims, on the one hand to quantify the rate of siltation in the case of the Boukourdane dam (northern Algeria), which is used to recharge groundwater. On the other hand, the article also shows the reduction in permeability in the capturing field with the current management of releases. Method. Solid rates were set in relation to the liquid flow and sediment concentration occasionally taken from the wadi. The relation established made it possible to evaluate the solid contributions to the dam of Boukourdane. The impact of the releases on recharging the well field was evaluated by grouping wells and the well field mushrooms using heuristic k-means. Regressions were applied to the piezometric variations of each group. Results. This dam is fed by a catchment area of 156 km². Sediment transport was estimated from empirical formulas. The specific degradation rate was estimated at 366 t.km-2.year-1 during the 1993 to 2005 period. The increase in the frequency of extreme rainfall resulted in an increase in the soil erosion rate to 446 t.km-2.year-1 during the 1993 to 2013 period. The volume of sediments accumulated in the dam reached 8.104 m³.year-1 and 11.104 m³.year-1 respectively during these two periods. Conclusions. A change in the management of current releases has a positive impact on the partial restoration of the hydraulic conductivity and de facto, on the fight against marine intrusion. [less ▲]

The use of uncoupled damage models has been widely used over the years for the prediction of ductile fracture in engineering applications. Nevertheless, its applicability in the prediction of failure has been shown to be limited in the wide range of loading conditions encountered in different manufacturing processes. In order to enhance the formulation of former damage models, the Lode angle has been recently used to characterize the stress states along with the stress triaxiality. This new family of damage models has been demonstrated to give excellent results when proportional loading paths are considered, but its efficiency in more complex applications still need further analysis. To this end, a comparative study of former and recently developed uncoupled damage models is performed in this work. The identification of material parameters is done considering simple mechanical tests under different conditions. Then, the models are used to predict the onset and propagation of cracks during blanking, where numerical predictions are compared with experimental results. Finally, the selected damage models presented a remarkable overall performance in the range of clearances under study. [less ▲]

This paper addresses the problem of efficiently operating the storage devices in an electricity microgrid featuring photovoltaic (PV) panels with both short- and long-term storage capacities. The problem of optimally activating the storage devices is formulated as a sequential decision making problem under uncertainty where, at every time-step, the uncertainty comes from the lack of knowledge about future electricity consumption and weather dependent PV production. This paper proposes to address this problem using deep reinforcement learning. To this purpose, a specific deep learning architecture has been designed in order to extract knowledge from past consumption and production time series as well as any available forecasts. The approach is empirically illustrated in the case of a residential customer located in Belgium. [less ▲]
