Runtime optimization of join location in parallel data management systems
Authors: Chandra Bikash , Sudarshan S.
Published: September 2017

Applications running on parallel systems often need to join a streaming relation or a stored relation with data indexed in a parallel data storage system. Some applications also compute UDFs on the joined tuples. The join can be done at the data storage nodes, corresponding to reduce side joins, or by fetching data from the storage system to compute nodes, corresponding to map side join. Both may be suboptimal: reduce side joins may cause skew, while map side joins may lead to a lot of data being transferred and replicated.

In this paper, we present techniques to make runtime decisions between the two options on a per key basis, in order to improve the throughput of the join, accounting for UDF computation if any. Our techniques are based on an extended ski-rental algorithm and provide worst-case performance guarantees with respect to the optimal point in the space considered by us. Our techniques use load balancing taking into account the CPU, network and I/O costs as well as the load on compute and storage nodes. We have implemented our techniques on Hadoop, Spark and the Muppet stream processing engine. Our experiments show that our optimization techniques provide a significant improvement in throughput over existing techniques.
Automating data citation in CiteDB

Published: September 2017

An increasing amount of information is being collected in structured, evolving, curated databases, driving the question of how information extracted from such datasets via queries should be cited. While several databases say how data should be cited for web-page views of the database, they leave it to users to manually construct the citations. Furthermore, they do not say how data extracted by queries other than web-page views --
general queries
-- should be cited. This demo shows how citations can be specified for a small set of views of the database, and used to
automatically generate citations for general queries
against the database.
Caching at the web scale
Authors: Zakhary Victor , Agrawal Divyakant , Abbadi Amr El
Published: September 2017

Today's web applications and social networks are serving billions of users around the globe. These users generate billions of key lookups and millions of data object updates per second. A single user's social network page load requires hundreds of key lookups. This scale creates many design challenges for the underlying storage systems. First, these systems have to serve user requests with low latency. Any increase in the request latency leads to a decrease in user interest. Second, storage systems have to be highly available. Failures should be handled seamlessly without affecting user requests. Third, users consume an order of magnitude more data than they produce. Therefore, storage systems have to be optimized for read-intensive workloads. To address these challenges, distributed in-memory caching services have been widely deployed on top of persistent storage. In this tutorial, we survey the recent developments in distributed caching services. We present the algorithmic and architectural efforts behind these systems focusing on the challenges in addition to open research questions.

L'enquête se donne pour objectif premier d'examiner en profondeur toutes les sources épigraphiques (principalement certains passages de la Loi de Gortyne) et narratives (en particulier certains passages de la „Politique“ d'Aristote) afin de dresser un état des lieux de la clémence parfaitement exceptionnelle de la législation et la juridiction des cités crétoises à l'égard des individus de statut servile. Dans un deuxième temps, on cherche à apporter des éléments d'explication, en élargissant la base documentaire avec l'appui des sources archéologiques.
Regionalentwicklung in einem postkolonialen Inselstaat im Globalen Süden: eine empirische Analyse der Republik Mauritius mit Zensus- und Surveydaten
Authors: Dirksmeier Peter
Published: September 2017

Die im südlichen Indischen Ozean gelegene, postkoloniale Inselrepublik Mauritius ist gegenwärtig Herausforderungen in ihrer Regionalentwicklung ausgesetzt, die in der Transformation der Insel von einer agrikulturellen, zuckerbasierten Gesellschaft hin zu einer diversen Ökonomie begründet sind. Die Verbesserung der Lebensbedingungen in allen Regionen des Inselstaates soll durch einen dreigliedrigen Ansatz der regionalen Entwicklung erreicht werden, der im Wesentlichen aus einer Sonderwirtschaftszone, dem internationalen Tourismus und Investitionen in die Informations- und Kommunikationstechnologie besteht. Der Aufsatz analysiert, ob diese Strategien erfolgreich in der Verbesserung der Lebensbedingungen in Mauritius sind. Die Regressionsanalyse verdeutlicht, dass lediglich der Informations- und Kommunikationssektor einen positiven Einfluss auf die Lebensbedingungen zeigt. Er ist allerdings hochgradig sozial selektiv. Dagegen weist der internationale Tourismus einen negativen Einfluss auf die Lebensbedingungen auf, da die parallel auftretende Verknappung von Immobilien zu hohen Wohnkosten in den touristischen Gebieten führt. Die Sonderwirtschaftszone zeigt ebenfalls einen schwachen, negativen Einfluss. Der Aufsatz folgert aus diesen Ergebnissen, dass die existierenden Regionalentwicklungspfade in Mauritius ambivalent sind und vorsichtiger politischer Anpassungen bedürfen, um das übergeordnete Ziel der Verbesserung der Lebensbedingungen auf der Insel zu erreichen.

Lgr5, leucine-rich repeat-containing G-protein coupled receptor 5, is abona fidebiomarker for stem cells in multiple tissues. Lgr5 is also expressed in the brain, but the identities and properties of these Lgr5+cells are still elusive. Using an Lgr5-EGFP reporter mouse line, we found that, from early development to adulthood, Lgr5 is highly expressed in the olfactory bulb (OB), an area with ongoing neurogenesis. Immunostaining with stem cell, glial, and neuronal markers reveals that Lgr5 does not label stem cells in the OB but instead labels a heterogeneous population of neurons with preference in certain subtypes. Patch-clamp recordings in OB slices reveal that Lgr5-EGFP+cells fire action potentials and display spontaneous excitatory postsynaptic events, indicating that these neurons are integrated into OB circuits. Interestingly, R-spondin 3, a potential ligand of Lgr5, is also expressed in the adult OB. Collectively, our data indicate that Lgr5-expressing cells in the OB are fully differentiated neurons and imply distinct roles of Lgr5 and its ligand in postmitotic cells.

SIGNIFICANCE STATEMENTLgr5 (leucine-rich repeat-containing G-protein coupled receptor 5) is abona fidestem cell marker in many body organs. Here we report that Lgr5 is also highly expressed in the olfactory bulb (OB), the first relay station in the brain for processing odor information and one of the few neural structures that undergo continuous neurogenesis. Surprisingly, Lgr5 is not expressed in the OB stem cells, but instead in a few subtypes of terminally differentiated neurons, which are incorporated into the OB circuit. This study reveals that Lgr5+cells in the brain represent a nonstem cell lineage, implying distinct roles of Lgr5 in postmitotic neurons.
Kaldor and Kornai on economics without equilibrium – two life courses
Authors: Mihalyi Peter
Published: September 2017

Nicholas Kaldor and János Kornai are known in the academic literature as the most principled and unyielding opponents of the neoclassical, mainstream economics in general, and the Arrow-Debreu General Equilibrium Theory (GET) in particular since the beginning of the 1970s. Nevertheless, they remained in the minority camp with their views until today. The mainstream of the economic profession still holds that only the neoclassical paradigm offers a comprehensive, systematic, consistent and, above all, mathematical (hence “scientific”) description of how modern economies operate. This paper aims at investigating why these two prolific writers, who were friends and spoke the same mother tongue, did not find a common ground and did not even try to build a school of followers jointly.

Permasalahan tersebut dapat diselesaikan dengan menggunakan model konseptual untuk menjamin keberlanjutan sumberdaya ikan tuna dan model konseptual untuk pembatasan penangkapan yuwana ikan tuna. Nusa Tenggara waters and its adjacent known as tuna’s migration area. That condition caused the high competition of tuna utilization in Nusa Tenggara waters.The research to define the issues of tuna utilization activities and to formulate the conceptual models to solve the problems. The results showed that the decreasing productivity of tuna fishing unit and undersized catch of tuna (juvenile) are the major concern that should be considered on arranging the management measures. Those problems could be solved by considering the conceptual model on the optimizing of productivity and limiting the catch of juvenile tuna.
Validation of the log e–log σ normal compression law using particle strength data
Authors: de Bono J. , McDowell G. R.
Published: August 2017

This note is a study of experimental data on particle strength and normal compression, to establish whether the normal compression law proposed by McDowell and de Bono in 2013 is supported and confirmed. A number of different sands are examined and found to support the hypothesis. In addition, some new simulations on sand mixtures are used to explain experimental results for quartz–feldspar mixtures. It would appear that the proposed compression law is also supported by the data for the sand mixtures.

Authors: J. AshokRaja , S. Balasankar , K. Mathiarasan
Published: August 2017

Background: Efficacy of wiping with a cloth compared to suction in routine care is not known. In term elective Lscs with clear liquor, we hypothesise that it has equivalent efficacy with suction.Methods: Randomized controlled equivalency trial with parallel group design. Inclusion criteria was term neonates born elective Lscs, with clear liquor and cried at birth at Government Rajaji Hospital, Madurai. Major congenital anomalies, Depressed or asphyxiated at birth, Meconium staining, Preterm were excluded. The Primary outcome is the time to reach a saturation of 92%. After randomisation, one group received gentle electrical suction and the other wiping of face, mouth and nose using a sterile cloth. The Pulseoximeter readings in the first fifteen minutes of life were transferred to a computer. Other clinical data collected using a Proforma.Results: Among 270 elective Lscs babies, 112 randomized, 58 received suction and 54 wiping. Excluding four babies, 56 Neonates in the suction group and 52 in the no suction group were analysed. The baseline data was similar except for maternal age. The primary outcome, median time to reach 92% saturation is significantly lesser (7 minutes (m)& 6 seconds(s)), [IQR 4m41s, 9m17s] in the no suction group, than the suction group (8 m18 s) [IQR 6m44s, 10m1s] (P value 0.009 ).Conclusions: In term elective LSCS babies with clear liquor and cried at birth, wiping with a sterile cloth has equivalent efficacy compared to suction for routine care.
“I Prefer Face-to-Face”: Comedic Moments in Teaching On-line
Authors: Roulston Kathryn , DeMarrais Kathleen
Published: August 2017

This script presents comedic moments experienced by professors teaching online. We examine instructor experiences of the “wheel of death,” the “hermeneutic circle of support,” the phenomenon of students taking coursework for purposes of convenience, instructors’ felt needs to always be at others’ service 24/7, and how instructors respond to students’ self-evident questions. In this short scene about learning to teach online, all characters appearing are fictitious. We share this with others because we argue that comedy is an effective way to respond to some of the challenges we have faced in learning to teach online.

Efecto Del Incremento De Intensidad Y Frecuencia Semanal Sobre La Condición Física En Personas Mayores Activas Que Proporcionan Los Programas: Ejercicio Funcional Con Bandas Elásticas Vs Lúdico- Recreativo
Authors: Franco Christian Hernán Ponce , Bravo Hernán Leopoldo Ponce , Cayo Henry Rodolfo Gutiérrez , Brito Karolina Janeth Cando , Machado Ramón Fernando Bayas
Published: September 2017

This study examines the impact of a program of functional exercise with elastic resistance band (centered on joint multi-resistance elastic band; experimental group, EG) versus an entertainment content (recreational exercise program compared to a recreational exercise program; control group, CG). It also examines the physical fitness in older active people who are over 60 years. Fifty-four volunteers who are residents of the community have an age range (70.57 ± 5.46 years). Before and after the intervention, physical fitness was determined through the Senior Fitness Test (strength, flexibility, aerobic endurance, and agility-dynamic balance) and the Manual Dynamometry Test. In the comparison INTER groups, the EG in flexibility improves p < 0.05 and in dynamic agility-balance p < 0.01. INTRA groups, EG and CG in leg and arm strength, presented improvements p < 0.001 and in manual isometry p < 0.05. Based on the flexibility of legs and arms, the EG presents improvements p < 0.05. Also, the CG only in right arm flexibility presents improvement p < 0.05. In agility-dynamic equilibrium, only the EG presents improvement p < 0.01. In expected aerobic performance, only the CG presented improvement p < 0.05. Strength improvement and increased manual grip maintain functional autonomy in both groups. Coupled with the improved agility-dynamic balance and flexibility of the EG, it gives the adult more independence which reduces the risk of falls in this population. In our findings, the EG significantly improved all fitness variables to a greater extent than CG. We recommend an increase in the intensity and frequency of physical activity programs and the inclusion of functional exercises with elastic bands aimed at this population.

Objective: To determine the prevalence and factors associated with neuropathic pain in patients with non-specific low back pain. Methods: This was a cross-sectional study conducted from May to July 2016 in the Rheumatology, Neurology and Neurosurgery departments of Lome. The DN4 questionnaire was used for the diagnosis of neuropathic pain in the 200 patients with low back pain included in this study. Results: Of the 200 patients (147 women and 53 men) included in the study, neuropathic pain was present in 92 (46%). The average age of the 92 patients (67 women vs 25 men, p = 0.04) was 55.5 ± 12.4 years (women 55.2 ± 12.8 vs. men 54.6 ± 11.4, p = 0.5). The characteristics of neuropathic pain mainly found were: burning sensation (n = 67, 72.8%); electrical discharges (n = 64, 69.6%); tingling (n = 90; 97.8%); tickling (n = 57; 62%); numbness (n = 89; 96.7%); hypoesthesia (n = 52; 56.5%). Factors significantly associated with the presence of neuropathic pain in LBP were age (p = 0.005), duration of LBP (p = 0.04), high blood pressure (p = 0.001), radicular pain (p = 0.00002) and the past history of the LBP (0.000000). Conclusion: Neuropathic pain is common in patients with LBP at Lome. The duration of LBP, past history of LBP, previous NSAID use, BMI, pain severity and radicular pain appear to be predictive of the occurrence of these neuropathic pains.

Authors: Aragão de Sousa Marlucy do Socorro , Guimaraes Jacqueline Tatiane da Silva , Castro César Augusto
Published: August 2017

This article addresses school practices and material culture in school in Belém Do Pará at the end of the nineteenth century. The objective is to analyze how material culture and school practices were articulated at the Colégio Americano, conceived by José Veríssimo between 1884 and 1890. The work Noticia Geral sobre o Collegio Americano is used as a source of information. The methodology used comprises a hermeneutic-historical approach. When analyzing the material culture of the school, the outlook includes a perception of its links with the historical, cultural and social context where a new model of education highlighting civility, nation and moral was created. Consequently, such devices were not just simple objects, but they revealed the conflictual or peaceful relations of this context, and even the school practices in the institution. It is observed that, for its creator, the use and the description of the objects placed in the Colégio Americano structure were intended to establish and maintain standards that should form disciplined men. They should be directly linked up with the purpose of physical, moral and civic education of students.
Programas para enseñar dibujo en la década de 1890

Published: August 2017

Sluys y Pouillot, autores traducidos y publicados en la Revista de Instrucción Pública de Colombia, podrían asumirse como voceros de dos corrientes pedagógicas de finales del siglo XIX. Mientras Sluys nos expone su postura experimental, desde la cual existiría un dibujo propio de los niños, en el que ellos expresaban sus sentimientos e ideas; Pouillot defiende el apoyo en la geometría y el trabajo manual, con el fin de formar el ojo y la mano, y enseñar la construcción de figuras planas mediante el uso de instrumentos y aplicarlas en la fabricación de objetos. A partir de las formas en las que cada autor fundamentaba sus concepciones, se derivaban los contenidos y métodos de enseñanza como fiel reflejo, no solo de sus formas de comprender el dibujo, los niños, el mundo en el que habitaban y su sentido de futuridad, sino también de dos posturas distantes que pugnaban por legitimarse entonces, luchas en las que se vieron implicadas las discusiones sobre las formas de enseñanza del arte.

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 184971, “Satellite Monitoring of Cyclic-Steam Stimulation Without Corner Reflectors,” by Michael D. Henschel and Jonathan Dudley, MDA, and Peter Chung, Canadian Natural Resources Limited, prepared for the 2017 SPE Canada Heavy Oil Technical Conference, Calgary, 15–16 February. The paper has not been peer reviewed.

Accurate monitoring of the ground deformation of a field under cyclic steam stimulation (CSS) can be used to calibrate predictive models, show the effectiveness of steam injection, and demonstrate the effect of the recovery operation on the surface elevation. Interferometric synthetic aperture radar (InSAR) uses radar returns from the ground to calculate highly precise estimates of the ground change. The authors discuss a new way of extracting deformation information from radar imagery, contributing to improved accuracy of InSAR surface-elevation monitoring.

Introduction

The challenge in the Canadian oil sands is to achieve robust measurements with limited infrastructure. Essentially, the problem is to develop robust measurements of the ground movement without reliance on buildings, pipelines, or even installed targets [such as corner reflectors (CRs)]. The case study described here shows exceptional results for monitoring of regions without traditional point targets.

The operations and mechanism of thermal recovery of steam-assisted gravity drainage (SAGD) and CSS differ. SAGD is a continuous process of balanced injection and production, while CSS is a cyclic process of injection, soaking, and depletion. The methodology provided depends on an understanding of the expected ground movement but does not rely on fore-knowledge of the motion itself. The rate of change in ground deformation associated with a CSS operation is key to the extraction of the signal (deformation) over the time required for this monitoring. The relatively short time scales and the high magnitude of the changes experienced in CSS are well-suited to the nontraditional methods described here.

The methods are validated by measurements of surface elevation by use of real-time kinematic (RTK) global-positioning-system (GPS) surveys acquired in the Primrose field coincident to the InSAR observations. The net-over-injection (NOI) metric provided by Canadian Natural Resources Limited (CNRL) is also used to demonstrate the causal relationship between injection and production volumes and the observed ground heave and subsidence, respectively.

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper SPE 183383, “Integrated Off-Bottom Cemented Inflow-Control-Device System Design Toward Well-Delivery Optimization,” by Mohammed A. Al Madan and Mazen Bu Khamseen, Saudi Aramco, and Hedy Suherdiana and Ahmad Al Abdulmohsen, Baker Hughes, a GE company, prepared for the 2016 Abu Dhabi International Petroleum Exhibition and Conference, Abu Dhabi, 7–10 November. The paper has not been peer reviewed.

Off-bottom-cementing (OBC) operations are unique to Saudi Arabia and represent a very challenging approach to drilling and workover operations when deployed in combination with inflow-control devices (ICDs) across horizontal sections. The multitasking-valve (MTV) feature in upgraded ICDs offers safe, simple, and cost-effective deployment operations. This paper discusses the first deployment of an ICD system combined with an OBC system for a workover operation in a mature producer well in the Kingdom of Saudi Arabia.

Introduction

In wells where an OBC liner is required to cover nontargeted formations above the production zone, two methods of deployment can be used: the one-trip system and the two-trip system. These refer, respectively, to whether the OBC components are deployed in a single trip along with the ICD or in a second trip with string in the previously deployed ICD completion. The one-trip OBC ICD completion does not allow an inner-string application. Therefore, circulation while running in hole was ineffective in this producer, which caused deployment problems.

The two-trip OBC ICD completion was then considered. The idea was to split the completion into a lower ICD completion, which is dropped off inside the openhole horizontal section with a setting sleeve. The earlier two-trip OBC ICD completion used an inner string, a circulating system, and an openhole-packer-setting tool. This allowed 100% circulation from the shoe during deployment of the lower ICD completion, although circulation rate is limited because of pumping through the small internal diameter (ID).

The upgraded ICD with an MTV allows the lower completion to be deployed without an inner string while achieving 100% circulation at the shoe, which smooths operations and saves up to 24 hours of rig time. The MTV temporarily blocks the communication between string and annulus while running in hole. Once reaching the setting depth, MTVs are actuated by hydraulic pressure. All hydraulically set equipment can also be set at this point.

Ultimately, in the case outlined in the complete paper, it was decided to combine once again the separated deployment into a single system by use of the MTV feature, which provides important functions for the one-trip OBC ICD completion—the ability to perform 100% circulation from the shoe and to set all hydraulic downhole tools with one setting ball.

Core Ideas

Competition of wheat varieties was assessed by growing them in neighboring plots.

The competitive abilities of the varieties were categorized using a linear mixed model.

Using the mixed model, we propose a measure to test the interaction of two varieties.

Competitive abilities can be used to identify varieties that may be grown in a variety mixture.

When two varieties are grown in neighboring plots, they compete for resources like nutrients, water, and solar energy. The performance of the two varieties under competition depends on their competitive ability, which comprises (i) the ability of a variety to withstand suppression by another variety and (ii) the ability to suppress the other variety. In this article, a linear mixed model was used to evaluate the competitive ability in terms of (i) and (ii). Furthermore, a measure to determine the synergistic effects of two competing varieties, which indicates if two competing varieties interact, is proposed. For illustration, we use yield data of six durum wheat varieties collected in trials during 2006–2007 and 2007–2008 using a split block design that provides all pairs of competing varieties. Estimating competitive abilities by the model proposed could prove helpful in exploiting the use of variety mixtures. Such mixtures were shown to be able to compete with, or even outperform, monocultures in different crops.

Core Ideas

Limited weed control tools is a challenge for pulse production in the northern Great Plains.

Soil‐applied residual herbicides are an important component of integrated weed management programs.

Most herbicide programs adequately controlled kochia and Russian‐thistle in the pulse crops.

Season‐long control of kochia and Russian thistle in dry pea, lentil, and chickpea.

Weed management is a challenge for pulse producers in the northern Great Plains (NGP). Multi‐location trials were conducted in Montana to evaluate crop safety and weed control in spring‐planted pulse crops from soil‐residual herbicides applied the previous fall in postharvest wheat (Triticum aestivum L.) stubble. Dry pea (Pisum sativum L.), lentil (Lens culinaris L.), and chickpea (Cicer arietinum L.) were planted the subsequent spring in herbicide‐treated plots. Metribuzin (210 or 420 g ha−1), flumioxazin (107 or 214 g ha−1), pyroxasulfone (119 or 238 g ha−1) + carfentrazone (8 or 16 g ha−1), pendimethalin (532 or 1064 g ha−1) + dimethenamid‐P (945 or 1890 g ha−1), sulfentrazone (164 or 328 g ha−1) + carfentrazone (18 or 36 g ha−1), sulfentrazone (101 or 202 g ha−1) + metribuzin (151 or 302 g ha−1) applied the previous fall had no significant visual injury (≤8% early‐season) or yield reductions in dry pea and chickpea. However, sulfentrazone‐based programs caused unacceptable crop injury (up to 75% early‐season) and yield reductions in lentil. Unacceptable early season injury and yield reductions were observed in pulse crops with thiencarbazone + isoxaflutole‐based programs. Metribuzin or pyroxasulfone + carfentrazone at twice the recommended fall‐use rate(s) and flumioxazin, sulfentrazone + carfentrazone, or sulfentrazone + metribuzin even at the recommended fall‐use rate(s) provided 75 to 99% end‐season control of kochia [Kochia scoparia (L.) Shrad.] and Russian‐thistle (Salsola tragus L.). These herbicide programs will provide new tools for weed control in pulse crops.
Evaluation of ‘Jackal’ AR601 (Avanex) and Kentucky‐31 Endophytic Tall Fescues for Suppressing Types of Invertebrates that Contribute to Bird Strike Hazard at Airports

Core Ideas

Endophytic grasses have been suggested for reducing bird strike hazard at airports.

Besides deterring geese, such grasses might suppress insects that attract birds.

Avanex tall fescue has been marketed as a bird‐deterrent grass for use at airports.

Avanex and KY‐31 were tested against invertebrates in field and greenhouse trials.

Neither grass is likely to appreciably reduce the food base for insectivorous birds.

Use of endophyte‐infected (E+) grasses to deter vertebrate grazers such as geese, and invertebrates attractive to insectivorous birds, has been proposed as a means to reduce bird strike hazard at airports. ‘Jackal’ tall fescue (Lolium arundinaceum) with the endophyte strain AR601, branded Avanex Unique Endophyte Technology and marketed as a bird‐deterrent grass, purportedly expresses inordinately high levels of both ergovaline to induce bird avoidance behavior and loline alkaloids for insect resistance. We tested the hypothesis that Avanex is more effective than Kentucky‐31 (KY‐31), a common tall fescue with wild‐type endophyte, for suppressing types of invertebrates fed on by birds. Bioactivity of Jackal AR601 and KY‐31, with or without their endophytes, was compared in insect feeding trials, and against macroinvertebrate communities in field plots. Presence of viable endophyte was confirmed by immunoblot and alkaloid analyses. Alkaloid concentrations varied seasonally but were no higher in Jackal AR601 than in E+ KY‐31. Both E+ grasses suppressed an endophyte‐sensitive aphid, but effects on grass‐feeding caterpillars were more subtle, with similar and some cases better larval growth and survival on Avanex than on KY‐31. Neither E+ grass reduced populations of earthworms, white grubs, or aboveground macroinvertebrates. This study suggests that suppression of invertebrates by Avanex or E+ KY‐31 is probably too weak to significantly reduce the food supply for insectivorous birds at airports.
