Modeling induced polarization effects in helicopter time domain electromagnetic data: Synthetic case studies
Authors: Viezzoli Andrea , Kaminski Vladislav , Fiandaca Gianluca 
Published: January 2017

We have developed a synthetic multiparametric modeling and inversion exercise undertaken to study the robustness of inverting airborne time-domain electromagnetic (TDEM) data to extract Cole-Cole parameters. The following issues were addressed: nonuniqueness, ill posedness, dependency on manual processing and the effect of constraints, and a priori information. We have used a 1D layered earth model approximation and lateral constraints. Synthetic simulations were performed for several models and the corresponding Cole-Cole parameters. The possibility to recover these models by means of laterally constrained multiparametric inversion was evaluated, including recovery of chargeability distributions from shallow and deep targets based on analysis of induced polarization (IP) effects, simulated in airborne TDEM data. Different scenarios were studied, including chargeable targets associated with the conductive and resistive environments. In particular, four generic models were considered for the exercise: a sulfide model, a kimberlite model, and two generic models focusing on the depth of investigation. Our study indicated that, in cases when relaxation time ([Formula: see text]) values are in the range to which the airborne electromagnetic is most sensitive (e.g., approximately 1 ms), it is possible to recover deep chargeable targets (to depths more than 130 m) in association with high electrical conductivity and in resistive environments. Furthermore, it was found that the recovery of a deep conductor, masked by a shallower chargeable target, became possible only when full Cole-Cole modeling was used in the inversion. Lateral constraints improved the recoverability of model parameters. Finally, modeling IP effects increased the accuracy of recovered electrical resistivity models.
Supporting patients with type 1 diabetes
Authors: Phillips Anne 
Published: January 2017

Patients with this autoimmune condition, and the health professionals who care for them, must be educated on ways to manage their condition, allowing them greater independence and lower the risk of complications. By Anne Phillips Type 1 diabetes is an autoimmune condition that is mediated by genetic, immunological and environmental factors. Its prevalence is further complicated by increasing obesity levels, and this can make diagnosis complicated. Health professionals play a key role in enabling and optimising person-centred care approaches to educate and augment the essential skills required for successful self-management of this lifelong condition. This article reflects on the physiology and aetiology of type 1 diabetes and prevalence and considers recent guidance from the National Institute for Health and Care Excellence for adults with type 1 diabetes (NG17) and for children and young people with type 1 and type 2 diabetes (NG18).
Personalised approaches for preventing asthma attacks
Authors: Marsh Viv 
Published: January 2017

Asthma is still potentially lethal, despite deaths from the condition being largely avoidable. Viv Marsh explores how management could be improved by personalised care It is poorly understood but asthma can be fatal. However most asthma deaths are avoidable. Avoidable factors relating to patients, health professionals and healthcare systems have been demonstrated. Recognition, identification and modification of avoidable factors could result in lives being saved. This article will explore the risk factors for asthma death and discuss therapeutic approaches to help patients of all ages achieve asthma control and avoid asthma attacks.
Evaluation of the Effectiveness of a Patient Centered Educational Mailer Designed
to Improve Statin Adherence: A Pragmatic Trial
Authors: Nord John W. , Berry Alalia , Stults Barry , Burningham Zachary , Beddhu Srinivasan , Sauer Brian C. 
Published: January 2017

Background: Patients with high total cholesterol have increased risk of
cardiovascular disease. National Cholesterol Education Program (NCEP) and American
Hearth Association (AHA) guidelines recommend cholesterol lowering with statin
medications; however, statin adherence remains poor. We hypothesized that
patient-centered education on the 10-year risk for each of the major constituents of
Cardiovascular Disease would increase statin adherence and achievement of low-density
lipoprotein cholesterol (LDL-C) goal.Methods: Veterans within the Salt Lake City
Veterans Affairs (VA) Medical Center initiating statin therapy during October 2008 to
December 2011 were randomized in a pragmatic design to either receive an educational
mailer or usual care. The mailer outlined their 10-year global cardiovascular risk,
separated into coronary heart disease, stroke, and congestive heart failure. The study
was unblinded and followed an intention-to-treat analysis where outcome measures were
obtained during normal care process. The primary outcome measure was achievement of
LDL-C goal during the 12-month follow-up.Results: Two hundred and seven patients were
randomly assigned to either the intervention arm (95) or control arm (112). No
differences in the proportion of patients meeting LDL-C goal were detected during
12-months [Relative Risk (RR): 0.95 (95%CI: 0.77-1.17)] or 18-months [RR: 1.03 (95%CI:
0.84, 1.25)]. Patients in the intervention arm had higher adherence on average, e.g.,
intervention patients were more likely to have 70% or more days of statin therapy
compared to patients who received standard care though this did not reach statistical
significance. [RR: 1.33(95%CI: 1.00, 1.78)] There were no statistical differences in
cardiovascular outcomes or mortality.Conclusion: Patient education mailers sent to
patients starting statin treatment did not have a clear impact on LDL-C goal achievement
or adherence to statin therapy.

Published: January 2017

Background Sepsis-associated cholestasis (SAC) is an intrahepatic cholestasis caused by inflammatory cytokines. Patients with this condition have poor prognoses. Antibiotics are the mainstay of therapy, however, other adjuvant therapies, such as ursodeoxycholic acid (UDCA), have not been well established.Objective To assess the effect ofUDCA for treatment ofneonatal sepsis-associated cholestasis.Methods We performed a randomized, double-blind, controlled trial in 3 7 neonates who were diagnosed with sepsis-associated cholestasis in the Neonatal Care Unit of Cipto Mangunkusumo Hospital. Subjects were divided into two groups, with 19 neonates randomly allocated to the intervention group (received UDCA at 30 tngikg/day divided into 3 doses for 7 days) and 18 neonates to the control group (received placebo) . After 7 days of treatment, we evaluated the subjects' liver function parameters and performed asurvival analysis.Results Liver function parameter improvements at day 7 were not significantly different between the UDCA group and the control group, including for mean decrease of total bilirubin (TB) levels [2.2 (SD 2.9) mg/dL vs 1.7 (SD 4.6) mg/dL; P=0.080), mean decrease of direct bilirubin (DB) levels [1.1 (SD 2.3) mg/dL vs 0.6 (SD 3.6) mg/dL; P=0.080), median indirect bilirubin (lB) levels [0.4 (range 0.1- 5.6) mg/dL vs 0.9 (range 0.1-4.1) mg/dL; P=0.358) , mean decrease of alanine aminotransferase (ALT) levels [0.5 (-80.0 -21.0) U/L vs -2.0 (ranged -167 .0 - 85.0) U/L; P= 0.730), median aspartate aminotransferase (AST) levels [ 43 .0 (range 14.0-297 .0) U/L vs 150.0 (range 24.0-840.0) U/L; P=0.081), and median gamma-glutamyl transpeptidase (GGf) levels [125.0 (48.0-481.0) U/L vs 235.0 (56.0-456.0) U/L; P=0.108)). Five neonates in control group died compared to two in the UDCA group (P=0.232). In addition, UDCA did not significantly lengthen the survival time (hazard ratio/HR 3.62; 95%CI 0.69 to 18.77) .Conclusion Ursodeoxycholic acid tends to improve total bilirubin, direct bilirubin, and AST levels in sepsis associated cholestasis .
Adaptive NUMA-aware data placement and task scheduling for analytical workloads in main-memory column-stores

Published: January 2017

Non-uniform memory access (NUMA) architectures pose numerous performance challenges for main-memory column-stores in scaling up analytics on modern multi-socket multi-core servers. A NUMA-aware execution engine needs a strategy for data placement and task scheduling that prefers fast local memory accesses over remote memory accesses, and avoids an imbalance of resource utilization, both CPU and memory bandwidth, across sockets. State-of-the-art systems typically use a static strategy that always partitions data across sockets, and always allows inter-socket task stealing.
In this paper, we show that adapting data placement and task stealing to the workload can improve throughput by up to a factor of 4 compared to a static approach. We focus on highly concurrent workloads dominated by operators working on a single table or table group (copartitioned tables). Our adaptive data placement algorithm tracks the resource utilization of tasks, partitions of tables and table groups, and sockets. When a utilization imbalance across sockets is detected, the algorithm corrects it by moving or repartitioning tables. Also, inter-socket task stealing is dynamically disabled for memory-intensive tasks that could otherwise hurt performance.
Sapprox
Authors: Zhang Xuhong , Wang Jun , Yin Jiangling 
Published: January 2017

In this paper, we aim to enable both efficient and accurate approximations on arbitrary sub-datasets of a large dataset. Due to the prohibitive storage overhead of caching offline samples for each sub-dataset, existing offline sample based systems provide high accuracy results for only a limited number of sub-datasets, such as the popular ones. On the other hand, current online sample based approximation systems, which generate samples at runtime, do not take into account the uneven storage distribution of a sub-dataset. They work well for uniform distribution of a sub-dataset while suffer low sampling efficiency and poor estimation accuracy on unevenly distributed sub-datasets.To address the problem, we develop a distribution aware method calledSapprox. Our idea is to collect the occurrences of a sub-dataset at each logical partition of a dataset (storage distribution) in the distributed system, and make good use of such information to facilitate online sampling. There are three thrusts in Sapprox. First, we develop a probabilistic map to reduce the exponential number of recorded sub-datasets to a linear one. Second, we apply thecluster sampling with unequal probability theoryto implement a distribution-aware sampling method for efficient online sub-dataset sampling. Third, we quantitatively derive the optimal sampling unit size in a distributed file system by associating it with approximation costs and accuracy. We have implemented Sapprox into Hadoop ecosystem as an example system and open sourced it on GitHub. Our comprehensive experimental results show that Sapprox can achieve a speedup by up to 20× over the precise execution.
Clay

Published: January 2017

Transaction processing database management systems (DBMSs) are critical for today's data-intensive applications because they enable an organization to quickly ingest and query new information. Many of these applications exceed the capabilities of a single server, and thus their database has to be deployed in a distributed DBMS. The key factor affecting such a system's performance is how the database is partitioned. If the database is partitioned incorrectly, the number of distributed transactions can be high. These transactions have to synchronize their operations over the network, which is considerably slower and leads to poor performance. Previous work on elastic database repartitioning has focused on a certain class of applications whose database schema can be represented in a hierarchical tree structure. But many applications cannot be partitioned in this manner, and thus are subject to distributed transactions that impede their performance and scalability.
In this paper, we present a new on-line partitioning approach, called Clay, that supports both tree-based schemas and more complex "general" schemas with arbitrary foreign key relationships. Clay dynamically creates blocks of tuples to migrate among servers during repartitioning, placing no constraints on the schema but taking care to balance load and reduce the amount of data migrated. Clay achieves this goal by including in each block a set of hot tuples and other tuples co-accessed with these hot tuples. To evaluate our approach, we integrate Clay in a distributed, main-memory DBMS and show that it can generate partitioning schemes that enable the system to achieve up to 15× better throughput and 99% lower latency than existing approaches.
Integrated Cloud-Based Services for Medical Workflow Systems
Authors: Gharbi Nada , Kirikova Mārīte , Bouzguenda Lotfi 
Published: January 2017

Abstract
Recent years have witnessed significant progress of workflow systems in different business areas. However, in the medical domain, the workflow systems are comparatively scarcely researched. In the medical domain, the workflows are as important as in other areas. In fact, the flow of information in the healthcare industry is even more critical than it is in other industries. Workflow can provide a new way of looking at how processes and procedures are completed in particular medical systems, and it can help improve the decision-making in these systems. Despite potential capabilities of workflow systems, medical systems still often perceive critical challenges in maintaining patient medical information that results in the difficulties in accessing patient data by different systems. In this paper, a new cloud-based service-oriented architecture is proposed. This architecture will support a medical workflow system integrated with cloud services aligned with medical standards to improve the healthcare system.
Simulation of Rock Mass Horizontal Displacements with Usage of Cellular Automata Theory.
Authors: Sikora Paweł 
Published: January 2017

Abstract
In the article there was presented two dimensional rock mass model as a deterministic finite cellular automata. Used to describe the distribution of subsidence of rock mass inside and on its surface the theory of automata makes it relatively simple way to get a subsidence trough profile consistent with the profile observed by geodetic measurements on the land surface. As a development of an existing concept of the rock mass model, as a finite cellular automaton, there was described distribution function that allows, simultaneously with the simulation of subsidence, to simulate horizontal displacements inside the rock mass model and on its surface in accordance with real observations. On the basis of the results of numerous computer simulations there was presented fundamental mathematical relationship that determines the ratio of maximum horizontal displacement and maximum subsidence, in case of full subsidence trough, in relation to the basic parameters of the rock mass model. The possibilities of presented model were shown on the example of simulation results of deformation distribution caused by extraction of abstract coal panel. Obtained results were consistent with results obtained by geometric-integral theory.
New Analytical Approaches for Evaluating the Performance of Systematic Pre-Tensioned Fully Grouted Rockbolts in Tunnel Stabilization
Authors: Ranjbarnia Masoud , Fahimifar Ahmad , Oreste Pierpaolo 
Published: January 2017

Abstract
In this paper, two new analytical approaches are presented on the basis of convergence-confinement method to compute both the ultimate convergence of circular tunnel and its plastic zone having been reinforced by systematically pre-tensioned fully grouted rockbolts. The models have two basic assumptions: (1) the grouted rockbolts increase the radial internal pressure within a broken rock mass by both the pre-tensioned force and the probable following induced force due to rock mass movement (2) tunnel convergence (specially short-term) occurs only due to reducing and diminishing of the radial constrained stress on tunnel surface provided by the working face. Hence, the values of both the pre-tensioned pressure and the mentioned radial constrained stress are specially taken into consideration in this paper. That is, according to their magnitudes, two different conditions occur: the magnitude of pre-tensioned pressure is greater than that of the constrained stress at bolt installation time and vice versa. The solutions are extended to each of conditions, and illustrative examples are solved. The proposed approaches predicting almost identical results show that pre-tensioning of grouted rockbolts will increase the efficiency and effectiveness of rockbolts.

Authors: Krawczyk Piotr , Majer Marzena , Krzemień Joanna 
Published: January 2017

Abstract
The paper presents possibilities of an economic evaluation of hard coal mines, using Cost Benefit Analysis (CBA). Suggested methodology for CBA applied to the economic evaluation of a mine allows to conduct a complex evaluation of mine’s functionality in connection to Polish conditions. Additionally to financial aspects, significant from the point of view of the mine’s owner, the paper includes social and environmental effects as a result of mining activities. Proposed methodology has undergone tests which used averaged data obtained from two selected hard coal mines located in the Upper Silesian Coal Basin. Presented results confirm the validity of social costs and benefits, and environmental losses resulting from mining operation, which were included in analysis comprehensively evaluating the efficiency of hard coal mines.
Visualizing EFL teacher identity (re)construction in materials design and implementation
Authors: de Laurentiis Brandão Ana Carolina 
Published: January 2017

AbstractThis study visually explores the process of identity (re)construction experienced by a pre-service EFL teacher as she designed and implemented English activities at Brazilian state schools. The theoretical framework draws from language teacher development, and narrative concepts on professional identity, teacher knowledge and context. Visual narratives, contextualized by written and oral narratives, are analysed for their holistic-content, taking into account a critical visual approach and a narrative inquiry methodology. The pre-service EFL teacher, whose experience is the focus of this paper, developed a metaphor to describe her process of identity (re)construction: the invisible English teacher. Stories of designing and implementing her own materials, and being part of different teaching landscapes play an important role in her search for visibility as an English teacher.
What Extent of Welfare Loss is Caused by the Disparity between Perceived and Scientific Risks? A Case Study of Food Irradiation
Authors: Watanabe Masahide , Kawata Yukichika 
Published: January 2017

Abstract
An individual perceived risk often differs from an objective risk based on the scientific evidence; risks about nuclear power generation and food technology including genetic modification and food irradiation are typical such cases. However, the extent to which welfare loss is caused by the disparity between perceived and scientific risks is unclear. Based on this gap in the literature, we conduct a discrete choice experiment to estimate the welfare loss. At the same time, we must tackle two issues arising in the estimation: endogeneity and ambiguity in the perceived risk. We construct an empirical model based on maxmin expected utility to consider ambiguity and apply a control function approach to alleviate endogeneity bias. The results show that 1) the disparity between perceived and scientific risks causes a significant welfare loss; 2) the ambiguity in the perceived risk exacerbates the welfare loss; and 3) endogeneity largely biases welfare measurement.
On the Topics and Style of Soviet Animated Films
Authors: Pikkov Ülo 
Published: January 2017

AbstractThis article provides a survey of Soviet animation and analyses the thematic and stylistic course of its development. Soviet animated film emerged and materialised in synch with the fluctuations of the region’s political climate and was directly shaped by it. A number of trends and currents of Soviet animation also pertain to other Eastern European countries. After all, Eastern Europe constituted an integrated cultural space that functioned as a single market for the films produced across it by filmmakers who interacted in a professional regional network of film education, events, festivals, publications etc.Initially experimental, post-revolutionary Russian animation soon fell under the sway of the Socialist Realist discourse, along with the rest of Soviet art, and quickly crystallised as a didactic genre for children. Disney’s paradigm became its major source of inspiration both in terms of visual style and thematic scope, despite the fact that Soviet Union was regarded as the ideological opposite of the Western way of life and mindset. The Soviet animation industry was spread across different studios and republics that adopted slightly varied production practices and tolerated different degrees of artistic freedom. Studios in the smaller republics, such as Estonia, Latvia and Lithuania in particular, stood out for making films that were more ideologically complicated than those produced in Moscow.
Alternative Networks of Globalisation: Latvian Neorealism in the Films of Laila Pakalniņa
Authors: Brūveris Klāra 
Published: January 2017

Abstract
This paper examines the development of neorealist tendencies in the oeuvre of contemporary Latvian filmmaker Laila Pakalnina. Her work is positioned within the global dissemination of cinematic neorealism, and its local manifestations, which, it is argued, develop in specific national contexts in reaction to dramatic societal and political changes. Pakalniņa’s films are examined as a documentation of the change from a communist satellite state to an independent democratic, capitalist country. Heavily influenced by the Riga School of Poetic Documentary, a movement in Latvian cinema that adhered to the conventions of poetic documentary filmmaking, the article analyses how her films replicate and further develop the stylistic and aesthetic devices of the Italian neorealists and the succeeding cinematic new waves. In doing so the argument is put forth that Pakalnina has developed neorealism Latvian style.
‘All the Necessary Information is Provided by Russia’s Channels’. Russian-language Radio and TV in Latvia: Audiences and Content
Authors: Rozukalne Anda 
Published: January 2017

AbstractAfter the Maidan events in Kiev and the annexation of Crimea in March 2014, discussions in Latvia expanded regarding the extent to which the Russian-speaking population in Latvia, whose daily information is obtained mainly from Russia’s TV channels, can get well-balanced and objective information. Opinion polls showed that a large proportion (41%) of the non-Latvians supported the annexation of Crimea and Russia’s President Vladimir Putin’s policy (SKDS 2014a). The aim of this article is to analyse the structure of the audiovisual media in the Russian language and media usage habits of the Russian-speaking audience using secondary and primary data. And thereby assess whether diversified information is available in the Russian language to this societal group. The research results show that the Russian-speaking population in Latvia does not feel a need for additional information channels, because they believe that the variety of information obtained from Russia’s TV and radio channels is sufficient.
