Hyppo-X: A Scalable Exploratory Framework for Analyzing Complex Phenomics Data
Authors: Kamruzzaman Methun , Kalyanaraman Ananth , Krishnamoorthy Bala , Hey Stefan , Schnable Patrick S. 
Published: July 2017

AbstractPhenomics is an emerging branch of modern biology that uses high throughput phenotyping tools to capture multiple environmental and phenotypic traits, often at massive spatial and temporal scales. The resulting high dimensional data represent a treasure trove of information for providing an in-depth understanding of how multiple factors interact and contribute to the overall growth and behavior of different genotypes. However, computational tools that can parse through such complex data and aid in extracting plausible hypotheses are currently lacking. In this paper, we presentHyppo-X, a new algorithmic approach to visually explore complex phenomics data and in the process characterize the role of environment on phenotypic traits. We model the problem as one of unsupervised structure discovery, and use emerging principles from algebraic topology and graph theory for discovering higher-order structures of complex phenomics data. We present an open source software which has interactive visualization capabilities to facilitate data navigation and hypothesis formulation. We test and evaluateHyppo-Xon two real-world plant (maize) data sets. Our results demonstrate the ability of our approach to delineate divergent subpopulation-level behavior. Notably, our approach shows how environmental factors could influence phenotypic behavior, and how that effect varies across different genotypes and different time scales. To the best of our knowledge, this effort provides one of the first approaches to systematically formalize the problem of hypothesis extraction for phenomics data. Considering the infancy of the phenomics field, tools that help users explore complex data and extract plausible hypotheses in a data-guided manner will be critical to future advancements in the use of such data.
Numerical simulation of serial launch process of multiple projectiles considering the aftereffect period
Authors: Luo Qiao , Zhang Xiaobing 
Published: July 2017

Purpose
The numerical simulation of the serial launch process of multiple projectiles is an important engineering problem. However, the projectiles’ motion law is hard to obtain completely only by interior ballistic model. The muzzle flow field affects the projectiles’ velocities when the projectiles pass through it. Also, the propellant gas from previous projectiles may decelerate the later projectiles. Therefore, the aftereffect period should be simulated together with the interior ballistic process of multiple projectiles when researching the serial launch process for accurate motion law of the projectiles.

Design/methodology/approach
The computational fluid dynamics (CFD) software is used to simulate the muzzle flow field. A one-dimensional two-phase reaction flow model is implemented in a computational code for the numerical simulation of gas-solid two-phase reaction flow, during the serial launch process. The computational code is coupled with CFD software by a user-defined function.

Findings
Compared with the first projectile, the formation process of the shock bottle of the second projectile is different. After the projectile head flies out of the muzzle, the projectile head pressure decreases rapidly, but then, it is not always equal to 0.1 MPa. After the projectiles leave the muzzle, the velocity increments of each projectile are mainly determined by muzzle pressure.

Originality/value
This paper presents a prediction tool to understand the projectiles’ motion law during the serial launch process of the multiple projectiles considering aftereffect period, and can be used as a research tool for future ballistic studies of a serial launch system of multiple projectiles.
Numerical study on the effects of variable properties and nanoparticle diameter on nanofluid flow and heat transfer through micro-annulus
Authors: Heydari Morteza , Shokouhmand Hossein 
Published: July 2017

Purpose
The purpose of this paper is to evaluate differences between the results of constant property and variable property approaches in solving the problem of Al2O3-water nanofluid heat transfer in an annular microchannel. Also, the effect of nanoparticle diameter on flow and heat transfer characteristics is investigated.

Design/methodology/approach
Thermo-physical properties of the nanofluid including density, specific heat, viscosity and thermal conductivity are assumed to be temperature dependent. Governing equations are descritized using the finite volume method and solved by SIMPLE algorithm.

Findings
The results reveal that the constant property assumption is unable to predict the correct trend of variations along the microchannel for some of the characteristics, especially when the range of temperature change near the wall is considerable. In the fully developed region, constant property solution overestimates the values of shear stress near the walls of the microchannel. In addition, the values of Nusselt numbers are different for the two solutions. Furthermore, a decrease in wall’s shear stress has been observed as a result of increasing nanoparticle size.

Originality/value
This paper reflects that how the friction factor and heat transfer vary along the microchannel in temperature dependent modeling, which is not reflected in the results of constant property approach. To the best of the authors’ knowledge, there is no similar investigation of the effect of nanofluid variable properties with Pr=5 or in annular geometry.
Solutions of the Blasius and MHD Falkner-Skan boundary-layer equations by modified rational Bernoulli functions
Authors: Calvert Velinda , Razzaghi Mohsen 
Published: July 2017

Purpose
This paper aims to propose a new numerical method for the solution of the Blasius and magnetohydrodynamic (MHD) Falkner-Skan boundary-layer equations. The Blasius and MHD Falkner-Skan equations are third-order nonlinear boundary value problems on the semi-infinite domain.

Design/methodology/approach
The approach is based upon modified rational Bernoulli functions. The operational matrices of derivative and product of modified rational Bernoulli functions are presented. These matrices together with the collocation method are then utilized to reduce the solution of the Blasius and MHD Falkner-Skan boundary-layer equations to the solution of a system of algebraic equations.

Findings
The method is computationally very attractive and gives very accurate results.

Originality/value
Many problems in science and engineering are set in unbounded domains. One approach to solve these problems is based on rational functions. In this work, a new rational function is used to find solutions of the Blasius and MHD Falkner-Skan boundary-layer equations.
A parallel partition of unity method for the nonstationary Navier-Stokes equations
Authors: Du Guangzhi , Zuo Liyun 
Published: July 2017

Purpose
The purpose of this paper is to propose a parallel partition of unity method (PPUM) to solve the nonstationary Navier-Stokes equations.

Design/methodology/approach
This paper opted for the nonstationary Navier-Stokes equations by using the finite element method and the partition of unity method.

Findings
This paper provides one efficient parallel algorithm which reaches the same accuracy as the standard Galerkin method but saves a lot of computational time.

Originality/value
In this paper, a PPUM is proposed for nonstationary Navier-Stokes. At each time step, the authors only need to solve a series of independent local sub-problems in parallel instead of one global problem.
Unsteady natural convection in a cubical cavity with a triangular heat source
Authors: Gibanov Nikita , Sheremet Mikhail 
Published: July 2017

Purpose
The purpose of this paper is to study natural convective fluid flow and heat transfer inside a cubical cavity having a local heat source of constant temperature.

Design/methodology/approach
The cubical cavity is cooled from two vertical opposite walls and heated from the local heater mounted on the bottom wall, while the rest walls are adiabatic. The governing equations formulated in dimensionless vector potential functions and vorticity vector have been solved using implicit finite difference method of the second-order accuracy. The effects of the Rayleigh number (Ra = 1e+04 – 1e+06), heat source position (l/L = 0.05 – 0.35) and dimensionless time (0 < tau < 100) on velocity and temperature fields, streamlines, isotherms and average Nusselt number at the heat source surface have been analyzed.

Findings
It is found that the extreme left position of the heater (l/L = 0.05) illustrates more essential cooling of the cavity where the thermal plume over the heat source is suppressed by low temperature waves from the cold vertical walls.

Originality/value
The originality of this work is to analyze transient 3D natural convection in a cubical cavity with a heater of triangular shape and compare obtained 3D data with 2D results. It should be noted that for numerical simulation, the authors used vector potential function and vorticity vector that for transient problems allows to reduce the computational time. The results would benefit scientists and engineers to become familiar with the analysis of transient convective heat and mass transfer in 3D domains with local heaters, and the way to predict the properties of convective flow in advanced technical systems, in industrial sectors including transportation, power generation, chemical sectors, ventilation, air-conditioning, etc.
The development of accounting education and practice in an environment of socio-economic transformation in the Middle East
Authors: Alsharari Nizar Mohammad 
Published: July 2017

Purpose
The purpose of this paper is to explore the development of accounting education and practice as influenced by the socio-economic transformation in Jordan.

Design/methodology/approach
The paper presents an explanatory study of how accounting education and practice has developed in relation to socio-economic change in Jordan, using the institutional economic theory-based constructivist approach, in which knowledge is constructed by compiling data from different sources, including historical and statistical analyses, documents, and archival records.

Findings
The study finds that accounting education in Jordan cannot be effectively studied without reference to how accounting practice affects, and is affected by the social, economic, political and cultural dimensions of its operating environment. The study finds that accounting change has been driven by the Jordanian Government’s response to the macroeconomic challenges that had historically restricted economic growth, including the scarcity of natural resources, budget deficits, soaring debt, and structural unemployment. The ongoing program of privatization has been a significant contributor to economic, accounting, and legal change. Since accountancy is accepted as a social practice, culture plays a significant role in accounting research, and cultural factors bearing on accounting education and practice in Jordan include the historical imposition of western accounting paradigms in developing countries, Jordan’s cultural values, the quality of its education system, and the disparity between the private sector’s and public management’s embrace of technology and applications for management accounting. The study finds that accounting education in Jordan cannot be effectively studied without reference to how accounting affects, and is affected by the social, economic, political and cultural dimensions of its operating environment.

Research limitations/implications
This paper describes the development of accounting education in an environment of socio-economic change, which has potential implications for accounting practitioners, academics, and policy makers in developing countries. The study’s constructivist approach selected with the aim of constructing a picture of the change environment, and thus, present new knowledge in a compilation of data limits, however, the generalizability of the findings.

Originality/value
The paper is a one of very few research studies in the accounting literature to present evidence from the Middle East of how accounting education and practice has developed in response to socio-economic transformation, and has itself contributed to socio-economic growth in Jordan. The significance of cultural factors in these developments provides further understanding of the dynamics of developing accounting education and practice in the era of globalization.

Pollination system of Corylopsis gotoana (Hamamelidaceae) and its stonefly (Plecoptera) co‐pollinator
Authors: Wong Sato Akira A. , Kato Makoto 
Published: July 2017

AbstractThe order Plecoptera is primarily known for its aquatic nymphs and their importance in many stream ecosystems. However, the biology and life history of Plecopteran terrestrial adults is mostly unknown, and hence interactions with plants have rarely been documented. Here, we report on insect visitation to flowers of Corylopsis gotoana (Hamamelidaceae) in a temperate forest of Japan, with emphasis on the behavior and pollination role of adults of a stonefly species, Strophopteryx nohirae (Taeniopterygidae), which were frequently observed in the flowers. The most frequent insect visitors to Corylopsis flowers were Bombylius major (Bombyliidae), Apis cerana (Apidae) and Bombus ardens (Apidae), all of which were considered main pollinators because of high rates of visitation and pollen attachment. Strophopteryx nohirae frequently visited Corylopsis trees, on which they foraged for pollen and mated. A field experiment on the pollination success of Corylopsis flowers visited by S. nohirae verified that this stonefly contributed to pollination.
Osteitis condensans ilii may demonstrate bone marrow edema on sacroiliac joint magnetic resonance imaging
Authors: Ma Ling , Gao Zhenhua , Zhong Yi , Meng Quanfei 
Published: July 2017

AbstractAimTo reveal whether bone marrow edema (BME) may appear with osteitis condensans ilii (OCI) on sacroiliac joint (SIJ) magnetic resonance imaging (MRI) and to evaluate the characteristics of BME demonstrated with OCI.MethodAltogether 27 symptomatic female OCI patients with both complete clinical records and SIJ‐MRI examination data were enrolled for retrospective analysis. SIJ‐MRI exams were retrospectively analyzed by two musculoskeletal radiologists. Patients were separated into BME group and non‐BME group according to whether there was BME of SIJ demonstrated as high signal intensity on MR short tau inversion recovery sequences beneath the SIJ articular surface. For the BME group the characteristics of BME including distribution pattern and location, depth and signal intensity were assessed.ResultsBME could be seen in 48.1% (13/27) OCI patients. Ilium side BME demonstrated with OCI was centered at the ventral‐cartilaginous joint part and had a trend of extending to bone marrow beneath the arcuate line in a continuous distribution pattern. There was a trend that OCI patients with BME demonstrated on MRI were younger (P = 0.054, Student's t‐test) and with shorter pain duration (P = 0.091, Student's t‐test) than OCI patients without BME, but the differences did not reaching statistical significance. More cases endured diagnosis delay in the BME group than the non‐BME group (nine cases vs. two cases, P = 0.006, Fisher's exact test).ConclusionSome OCI may demonstrate BME on SIJ‐MRI. Careful observation of the location and distribution pattern of BME may give some help in differentiating OCI from early spondyloarthritis.
Know your industry: the implications of using static GICS classifications in financial research
Authors: Katselas Dean , Sidhu Baljit K. , Yu Chuan 
Published: July 2017

AbstractResearchers commonly use industry classifications as a means of identifying peer companies to use as a performance benchmark. We describe the structure of commonly used sources of industry classification data available for Australian listed companies, both static and in time series. Next, we run a series of experiments matching firms according to GICS classification data presented in time series versus static data sources. Our results indicate that performance measures are better specified when matching on GICS data from a dynamic relative to a static source. The results of our power tests also underscore the importance of using dynamic industry data.

Published: July 2017

ObjectiveThe study investigates and compares the services available in different types of registered retirement villages in Queensland (QLD).MethodsA content analysis based on official websites of 175 registered villages in QLD, Australia, is presented.ResultsThis study identifies 82 services, with activity organisation, emergency response, hairdressing and transportation being most frequently available to residents. The number of services available is associated with the village size and financial type, with residents living in large private villages having access to significantly more services.ConclusionThe research findings reveal the state of the art of current industry practice. They provide useful implications for stakeholders. For instance, residents who prefer to get access to various services should focus more on large private villages. Developers can check their service delivery environment to confirm its balance with residents’ competencies. The government can propose innovative initiatives to promote the delivery of appropriate services in villages.
A novel in vitro model of villitis of unknown etiology demonstrates altered placental hormone and cytokine profile
Authors: Derricott Hayley , Heazell Alexander E.P. , Greenwood Susan L. , Jones Rebecca L. 
Published: July 2017

ProblemPlacental dysfunction is present over 50% of cases of stillbirth and fetal growth restriction (FGR). Villitis of unknown etiology (VUE), an inflammatory condition of the placenta characterized by maternal T cell infiltrates in the villous stroma and dysregulation of inflammatory cytokines, is more frequent in FGR and stillbirth.Method of studyA novel in vitro model of placental inflammation was developed to test the hypothesis that inflammatory cells seen in VUE and/or cytokines impair placental function.ResultsCoculture of placental explants with maternal leukocytes resulted in increased leukocytes in villous tissue and elevated concentrations of IL‐1β, IL‐1Ra, IL‐6, IL‐10, and IFN‐γ (P≤.05). Human chorionic gonadotrophin secretion was reduced following coculture with leukocytes (P≤.01) and cytokines (P≤.05).ConclusionThese observations support the hypothesis that altered placental inflammation has deleterious effects on placental function. This model could be used to further understanding about the pathophysiology of VUE and to test potential therapies.

Authors: Filoche Sara K. , Lawton Beverley , Beard Angela , Stone Peter 
Published: July 2017

BackgroundNon‐invasive prenatal testing (NIPT) has been available in Aotearoa New Zealand (NZ) for approximately four years. It is likely to be introduced into the publicly funded prenatal screening service.AimTo explore obstetrician use and views of NIPT, with consideration to its implementation into screening services for Down syndrome and other conditions.MethodsAn anonymous online survey combining Likert scales and free text was designed to assess current practice, knowledge, ethical considerations, counselling and views toward public funding of NIPT. The survey was distributed through the New Zealand members of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (n = 418) and responses collected over a two‐month period in 2016.ResultsThere were 134/418 (32.1%) respondents. Current knowledge influenced decisions to offer NIPT (70.3%, 85/121). Confidence in offering NIPT was: ‘not at all’ (0.8%, 1/128); ‘a little’ (7.03%, 9/128), ‘somewhat’ (16.4%, 21/128), ‘quite’ (40.6%, 52/128) and ‘very’ (35.2%, 45/128). A total of 83.5% (101/121) stated NIPT should be publicly funded and NIPT capability developed within NZ (89.1%, 106/119). More information and support on the provision of NIPT was called for.ConclusionThere was strong support for public funding of NIPT, and for NIPT capability to be developed in NZ. The call for more training, education and support needs to be actioned in order to facilitate the introduction of NIPT into screening services.
