Building an Encrypted, Distributed, and Searchable Key value Store
Venue: AsiaCCS

Modern distributed key value stores are offering superior performance, incremental scalability, and fine availability for data intensive computing and cloud based applications. Among those distributed data stores, the designs that ensure the confidentiality of sensitive data, however, have not been fully explored yet. In this paper, we focus on designing and implementing an encrypted, distributed, and searchable key value store. It achieves strong protection on data privacy while preserving all the above prominent features of plaintext systems. We first design a secure data partition algorithm that distributes encrypted data evenly across a cluster of nodes. Based on this algorithm, we propose a secure transformation layer that supports multiple data models in a privacy preserving way, and implement two basic APIs for the proposed encrypted key value store. To enable secure search queries for secondary attributes of data, we leverage searchable symmetric encryption to design the encrypted secondary indexes which consider security, efficiency, and data locality simultaneously, and further enable secure query processing in parallel. For completeness, we present formal security analysis to demonstrate the strong security strength of the proposed designs. We implement the system prototype and deploy it to a cluster at Microsoft Azure. Comprehensive performance evaluation is conducted in terms of Put/Get throughput, Put/Get latency under different workloads, system scaling cost, and secure query performance. The comparison with Redis shows that our prototype can function in a practical manner.
Automatic Recognition of Conversational Strategies in the Service of a Socially Aware Dialog System
Venue: SIGDIAL Conference

In this work, we focus on automatically recognizing social conversational strategies that in human conversation contribute to building, maintaining or sometimes destroying a budding relationship. These conversational strategies include self disclosure, reference to shared experience, praise and violation of social norms. By including rich contextual features drawn from verbal, visual and vocal modalities of the speaker and interlocutor in the current and previous turn, we can successfully recognize these dialog phenomena with an accuracy of over 80% and kappa ranging from 60 80% Our findings have been successfully integrated into an end to end socially aware dialog system, with implications for virtual agents that can use rapport between user and system to improve task oriented assistance.
Genome analysis and avirulence gene cloning using a high density RADseq linkage map of the flax rust fungus, Melampsora lini
Venue: BMC Genomics

BackgroundRust fungi are an important group of plant pathogens that cause devastating losses in agricultural, silvicultural and natural ecosystems. Plants can be protected from rust disease by resistance genes encoding receptors that trigger a highly effective defence response upon recognition of specific pathogen avirulence proteins. Identifying avirulence genes is crucial for understanding how virulence evolves in the field.ResultsTo facilitate avirulence gene cloning in the flax rust fungus, Melampsora lini, we constructed a high density genetic linkage map using single nucleotide polymorphisms detected in restriction site associated DNA sequencing (RADseq) data. The map comprises 13,412 RADseq markers in 27 linkage groups that together span 5860 cM and contain 2756 recombination bins. The marker sequences were used to anchor 68.9 of the M. lini genome assembly onto the genetic map. The map and anchored assembly were then used to: 1) show that M. lini has a high overall meiotic recombination rate, but recombination distribution is uneven and large coldspots exist; 2) show that substantial genome rearrangements have occurred in spontaneous loss of avirulence mutants; and 3) identify the AvrL2 and AvrM14 avirulence genes by map based cloning. AvrM14 is a dual specificity avirulence gene that encodes a predicted nudix hydrolase. AvrL2 is located in the region of the M. lini genome with the lowest recombination rate and encodes a small, highly charged proline rich protein.ConclusionsThe M. lini high density linkage map has greatly advanced our understanding of virulence mechanisms in this pathogen by providing novel insights into genome variability and enabling identification of two new avirulence genes.

Drivers and pressures Untangling the terms commonly used in marine science and policy.
Venue: Journal of environmental management

In the marine sciences an increasing number of studies on environmental changes, their causes, and environmental assessments emerged in recent years. Often authors use non uniform and inconsistent definitions of key terms like driver, threats, pressures etc. Although all of these studies clearly define causal dependencies between the interacting socio economic and environmental systems in an understandable way, still an overall imprecise wording could induce misunderstanding at higher policy levels when it comes to integrated ecosystems assessments. Therefore we recommend using unified definitions for a better communication between science and management within national, regional and international environmental policies, for example the European Marine Strategy Framework Directive (MSFD) With this article we provide definitions compatible with the driver pressure state impact response (DPSIR) approach. Although most examples are MSFD related and thus have a marine focus the definitions are intended to be equally applicable for other systems and are usable world wide. We suggest sticking to these definitions for an easy and simplified knowledge transfer from science to management, since DPSIR model is already accepted as a helpful tool for structuring and communicating ecosystem analyses.
Asymptotically one dimensional dynamics of high peak power ultrashort laser pulses

Laser fields with peak powers P well above the critical power of self focusing P cr are intrinsically unstable with respect to modulation instabilities, breaking up into multiple filaments as a part of a quintessentially three dimensional nonlinear beam dynamics. Here, however, we show that even for P P cr the spatiotemporal field evolution can stay effectively one dimensional. In this regime, observed as an asymptotic case of large diffraction lengths, the laser field can undergo a rich diversity of pulse transformation scenarios, including, most notably, pulse self compression to subcycle field waveforms with very high peak powers, while remaining decoupled, within a limited propagation length, from beam dynamics.
Adaptive semi greedy search for multidimensional track assignment
Venue: 2016 19th International Conference on Information Fusion (FUSION)

Robust multitarget, multisensor fusion algorithms rely on optimal or near optimal assignment algorithms at their core. Greedy and semi greedy search algorithms represent a fast and effective solution to multi dimensional assignment problems, at the cost of often producing sub optimal results in challenging cases. The Adaptive Semi Greedy Search (ASGS) presented here is an improvement on older semi greedy search methods, and is more likely to find the optimal solution without sacrificing computational speed. ASGS outperforms Semi Greedy Track Selection (SGTS) in a wide range of statistical tests, where it was consistently more likely to find the optimal solution to 6 dimensional assignment problems, as if the RMS measurement error had been reduced by 25% The two algorithms are also compared in several challenging multitarget, multisensor tracking scenarios, including maneuvering formations and crossing targets, where a Multiple Hypothesis Tracker (MHT) using the ASGS significantly reduces the RMS position error of the tracks (p 0.001 for each scenario) The ASGS effectively increases the range of scenarios in which semi greedy assignment algorithms can be reliably employed, especially valuable for real time applications with large number of targets and sensors.
RELPRON: A Relative Clause Evaluation Data Set for Compositional Distributional Semantics
Venue: CL

This article introduces RELPRON, a large data set of subject and object relative clauses, for the evaluation of methods in compositional distributional semantics. RELPRON targets an intermediate level of grammatical complexity between content word pairs and full sentences. The task involves matching terms, such as "wisdom," with representative properties, such as "quality that experience teaches." A unique feature of RELPRON is that it is built from attested properties, but without the need for them to appear in relative clause format in the source corpus. The article also presents some initial experiments on RELPRON, using a variety of composition methods including simple baselines, arithmetic operators on vectors, and finally, more complex methods in which argument taking words are represented as tensors. The latter methods are based on the Categorial framework, which is described in detail. The results show that vector addition is difficult to beat in line with the existing literature but that an implementation of the Categorial framework based on the Practical Lexical Function model is able to match the performance of vector addition. The article finishes with an in depth analysis of RELPRON, showing how results vary across subject and object relative clauses, across different head nouns, and how the methods perform on the subtasks necessary for capturing relative clause semantics, as well as providing a qualitative analysis highlighting some of the more common errors. Our hope is that the competitive results presented here, in which the best systems are on average ranking one out of every two properties correctly for a given term, will inspire new approaches to the RELPRON ranking task and other tasks based on linguistically interesting constructions.
Relative clause extraposition and prosody in German

Whether a relative clause (RC) can be extraposed has been argued to depend both on contextual focus and on whether an RC is restrictive or appositive. However, no previous study has looked at the interaction between these two factors in restricting extraposition, despite the fact that different types of relative clauses are generally taken to differ in how they relate to focus. Furthermore, previous studies have not looked at the role of prosody in accounting for the effect of focus on extraposition, and have found contradictory results with respect to the prosodic differences between appositive and restrictive relative clauses. This paper presents the results of a production experiment on German which crosses the location of focus and the type of RC in order to explore how they interact in affecting prosody and extraposition.
El acido acetilsalicilico reduce la liberacion de microparticulas eritrocitarias, monocitarias y de celulas del musculo liso vascular en pacientes diabeticos

Resumen Introduccion y objetivos La diabetes mellitus esta asociada a mayor riesgo de enfermedad cardiovascular y su prevalencia esta en aumento. La diabetes mellitus induce estres metabolico a las celulas vasculares, lo cual promueve la activacion plaquetaria y la disfuncion vascular. El grado de activacion de las celulas vasculares se puede medir con el numero y el fenotipo de las microparticulas circulantes. El objetivo de este estudio es investigar el efecto de una dosis de acido acetilsalicilico con accion inhibidora plaquetaria en el numero y el tipo de las microparticulas liberadas a la circulacion. Metodos Se inscribio a 43 pacientes diabeticos que recibieron una dosis diaria de 100 mg de acido acetilsalicilico durante 10 dias, con objeto de cubrir el periodo medio de vida de las plaquetas en la circulacion. Antes y despues del periodo de intervencion, se caracterizaron y cuantificaron las microparticulas circulantes mediante citometria de flujo. Resultados Respecto a los pacientes con diabetes mellitus tipo 2, aquellos con diabetes mellitus tipo 1 presentaron el doble de microparticulas circulantes positivas para factor tisular (derivadas de plaquetas y monocitos) y microparticulas positivas para selectina E de origen endotelial. El tratamiento con acido acetilsalicilico inhibio significativamente las plaquetas, puesto que la generacion de tromboxano derivado de la ciclooxigenasa 1 disminuyo un 99% Se produjo una reduccion significativa de las microparticulas derivadas de eritrocitos, monocitos activados y celulas de musculo liso tras 10 dias de administracion de acido acetilsalicilico. Conclusiones Estos resultados indican que: a) las celulas vasculares y hematicas de los pacientes con diabetes mellitus tipo 1 estan expuestas a un mayor estres continuo, que se refleja en el origen y la cantidad de sus microparticulas; b) el tratamiento con acido acetilsalicilico inhibe la activacion de las celulas de la pared vascular y la liberacion de microparticulas, y c) los efectos del acido acetilsalicilico son similares en la diabetes mellitus tipos 1 y 2.
Creep testing of concrete since setting time by means of permanent and repeated minute long loadings

Monitoring the evolution of early age properties of concrete is necessary to provide input data to the models of prediction of the behavior of concrete structures since setting time. The experimental challenge lies in the fact that this monitoring must be fully automatic since the earliest age because the hardening process of the concrete takes place continuously over a period counted in hours and even in days after the casting time. This research paper presents a new methodology developed at ULB and IFSTTAR to monitor the creep and relaxation of an ordinary concrete chosen as reference concrete since setting time. Compressive creep rigs and two test devices were used: at ULB, a Temperature Stress Testing Machine (TSTM) specifically designed for testing concrete since setting time under free and restraint conditions and at IFSTTAR, a test set up called BTJASPE developed to monitor, in compression, the modulus of elasticity, the creep and the relaxation of a concrete since very early age. For the sake of the study, the same concrete has been used in the two laboratories. In addition, this study is performed at a constant temperature to exclude this parameter, at this step of the study. The methodology is based on experimental measurements with two kinds of test. A classical creep test with permanent loading during one week and a repeated minute long loading test for which every 30 min, a loading is applied and kept constant during 5 min and finally totally removed. The classical test is used to characterize the non aging creep function and the repeated minute long loading test is used to quantify the aging creep functions.
Dissimilar metal deposition with a stainless steel and nickel based alloy using wire and arc based additive manufacturing

The wire and arc based additive manufacturing process applies arc welding technology; the wire material is melted by the arc discharge, and is then accumulated successively in this process. The wire and arc based additive manufacturing process directly and locally adds material to the molten pool. By changing the material locally during the process, more than one kind of material can be used simultaneously in a single manufactured component. In this study, two kinds of dissimilar metal deposition were conducted. A combination used was a stainless steel and Ni based alloy. Mechanical properties near the interface such as hardness and bond strength were investigated. As a result, it was found that the mechanical properties of the manufactured alloy were comparable to those of a bulk material. In addition, an additive manufacturing system and a torch path planning method for using more than two kinds of material were proposed. By using this method, highly functional shapes whose surfaces and inner structures are made of different material could be made.
Deriving the Metal and Alloy Networks of Modern Technology.
Venue: Environmental science technology

Metals have strongly contributed to the development of the human society. Today, large amounts of and various metals are utilized in a wide variety of products. Metals are rarely used individually but mostly together with other metals in the form of alloys and/or other combinational uses. This study reveals the intersectoral flows of metals by means of input output (IO) based material flow analysis (MFA) Using the 2007 United States IO table, we calculate the flows of eight metals (i.e. manganese, chromium, nickel, molybdenum, niobium, vanadium, tungsten, and cobalt) and simultaneously visualize them as a network. We quantify the interrelationship of metals by means of flow path sharing. Furthermore, by looking at the flows of alloys into metal networks, the networks of the major metals iron, aluminum, and copper together with those of the eight alloying metals can be categorized into alloyed nonalloyed (i.e. individual) and both mixed. The result shows that most metals are used primarily in alloy form and that functional recycling thereby requires identification, separation, and alloy specific reprocessing if the physical properties of the alloys are to be retained for subsequent use. The quantified interrelation of metals helps us consider better metal uses and develop a sustainable cycle of metals.
Promoting the Performance of Layered Material Photodetectors by Alloy Engineering.
Venue: ACS applied materials interfaces

The successful peeling of graphene heralded the era of van der Waals material (vdWM) electronics. However, photodetectors based on semiconducting transition metal dichalcogenides (TMDs) formulated as MX2 (M Mo, W; X S, Se) often suffer either poor responsivity or long response time because of their high density of deep level defect states (DLDSs) Alloy engineering, which can shift the DLDSs to shallow level defect states, is proposed to be an efficient strategy to solve this problem. However, proof of concept is still lacking, which is probably because of the absence of a facile technology to grow high quality alloyed TMDs. Here, we report the growth of large scale and high quality Mo0.5W0.5S2 alloy films via pulsed laser deposition (PLD) We demonstrate that the resulting Mo0.5W0.5S2 photodetector possesses a stable photoresponse from 370 to 1064 nm. The photocurrent exhibits positive dependence on both the source drain voltage and incident power density, providing good tunability for multifunctional photoelectrical applications. We also establish that, because of the suppression of DLDSs with alloy engineering, the Mo0.5W0.5S2 photodetector achieves a good responsivity of 5.8 A/W and a response time shorter than 150 ms. The working mechanism for the suppression of DLDSs in Mo0.5W0.5S2 is unveiled by qualitatively analyzing the alloying dressed band structure. In conclusion, the excellent performance of the PLD grown Mo0.5W0.5S2 photodetector may pave the way for next generation photodetection. The approach shown here represents a fundamental and universal scenario for the development of alloyed TMDs.
Application of critical path analysis for permeability prediction in natural porous media

Critical path analysis (CPA) originally developed to describe electrical conductance in semiconductors, has been shown recently to hold some promise in describing transport properties of porous media. I applied some previously developed concepts in CPA and percolation theory to predict permeability in a suite of sandstone, carbonate, and clay rich samples. I assumed that the pore sizes in my samples exhibited fractal scaling and expressed the electrical formation factor as a function of porosity using universal scaling from percolation theory. The resulting CPA permeability predictions match the measured values very well. In addition, I show how considering the scale dependence of the percolation threshold yields two characteristic length scales for transport properties: the critical pore size, and the sample size. This work suggests that the CPA framework is appropriate for describing transport properties of natural porous media, and provides a theoretical basis for understanding the permeability of tight rocks like shale in which laboratory permeability measurements are difficult.
Relative permeability to water or gas in the presence of hydrates in porous media from critical path analysis

Most existing models for predicting relative permeability in the presence of hydrate are either empirical or based on simplistic representations of the pore system and hydrate growth. Multiple models are often needed to explain relative permeability behavior observed in the laboratory over different ranges of hydrate saturation. Critical path analysis (CPA) offers a framework for predicting relative permeability based on pore system properties, including the percolation threshold and breadth of the pore size distribution. Using an existing method developed for partially saturated soils, I show that CPA can accurately predict relative permeability to either water or gas over the entire range of measured hydrate saturation for several suites of laboratory measurements. The method does not require any assumption of hydrate growth habit, and assumes that hydrate tends to grow in the largest pores first. This work represents an improvement in understanding the link between pore structure and transport properties of hydrate bearing sediment.
Quantifying tight gas sandstone permeability via critical path analysis

Rock permeability has been actively investigated over the past several decades by the geosciences community. However, its accurate estimation still presents significant technical challenges, particularly in spatially complex rocks. In this short communication, we apply critical path analysis (CPA) to estimate permeability in porous rocks from measured mercury intrusion porosimetry and electrical conductivity data. Theoretical estimations of various CPA based models are then compared to experimental measurements using eighteen tight gas sandstones. Except for two of the samples, we find permeability estimations performed with the Skaggs model (assuming pore diameter independent of its length) more accurate than other models, within a factor of two of the measured permeabilities. We discuss some plausible sources of the uncertainties.
