Preliminary simulations of scale and value of legitimation in design practice

This paper presents preliminary simulation results on the effects of scale and value of legitimation in design practice. The paper describes a basic simulation model, which adopts legitimation code theory as the underlying conceptual framework. This model simulates a society of design agents with different backgrounds. Based on the given legitimation values of their discipline, agents are attracted towards knowers or knowledge. The force of attraction towards the knower or knowledge varies across disciplines. The emergent design practice is plotted in a two dimensional space defined by the knower and knowledge axes. The effect of scale is studied by changing the number of agents. The effect of value is studied by comparing scenarios where legitimation values of a design agent remain constant throughout the simulations to scenarios where legitimation values increase at a constant rate, as a function of time spent in a multi-disciplinary environment. Preliminary results indicate that both scaling up and changing values can lead to cohesive design practice in multi-disciplinary societies. The underlying assumptions and limitations of the simulation model are discussed.
Arctic Deep Water Ferromanganese‐Oxide Deposits Reflect the Unique Characteristics of the Arctic Ocean

Little is known about marine mineral deposits in the Arctic Ocean, an ocean dominated by continental shelf and basins semi‐closed to deep‐water circulation. Here, we present data for ferromanganese crusts and nodules collected from the Amerasia Arctic Ocean in 2008, 2009, and 2012 (HLY0805, HLY0905, and HLY1202). We determined mineral and chemical compositions of the crusts and nodules and the onset of their formation. Water column samples from the GEOTRACES program were analyzed for dissolved and particulate scandium concentrations, an element uniquely enriched in these deposits. The Arctic crusts and nodules are characterized by unique mineral and chemical compositions with atypically high growth rates, detrital contents, Fe/Mn ratios, and low Si/Al ratios, compared to deposits found elsewhere. High detritus reflects erosion of submarine outcrops and North America and Siberia cratons, transport by rivers and glaciers to the sea, and distribution by sea ice, brines, and currents. Uniquely high Fe/Mn ratios are attributed to expansive continental shelves, where diagenetic cycling releases Fe to bottom waters, and density flows transport shelf bottom water to the open Arctic Ocean. Low Mn contents reflect the lack of a mid‐water oxygen minimum zone that would act as a reservoir for dissolved Mn. The potential host phases and sources for elements with uniquely high contents are discussed with an emphasis on scandium. Scandium sorption onto Fe oxyhydroxides and Sc‐rich detritus account for atypically high scandium contents. The opening of Fram Strait in the Miocene and ventilation of the deep basins initiated Fe‐Mn crust growth ∼15 Myr ago.
Modelling asset correlations: A nonparametric approach

This article proposes a time-varying nonparametric estimator and a time-varying semiparametric estimator of the correlation matrix. We discuss representation, estimation based on kernel smoothing and inference. An extensive Monte Carlo simulation study is performed to compare the semiparametric and nonparametric models with the DCC specification. Our bivariate simulation results show that the semiparametric and nonparametric models are best in DGPs with gradual changes or structural breaks in correlations. However, in DGPs with rapid changes or constancy in correlations the DCC delivers the best outcome. Moreover, in multivariate simulations the semiparametric and nonparametric models fare the best in DGPs with substantial time-variability in correlations, while when allowing for little variability in the correlations the DCC is the dominant specification. The methodologies are illustrated by estimating the correlations for two interesting portfolios. The rst portfolio consists of the equity sectors SPDRs and the S&P 500 composite, while the second one contains major currencies that are actively traded in the foreign exchange market. Portfolio evaluation results show that the nonparametric estimator generally dominates its competitors, with a statistically significant lower portfolio variance.
Correlation between structure and electrical transport in ion-irradiated graphene grown on Cu foils

Graphene grown by chemical vapor deposition and supported on SiO2 and sapphire substrates was studied following controlled introduction of defects induced by 35 keV carbon ion irradiation. Changes in Raman spectra following fluences ranging from 1012 cm-2 to 1015 cm-2 indicate that the structure of graphene evolves from a highly-ordered layer, to a patchwork of disordered domains, to an essentially amorphous film. These structural changes result in a dramatic decrease in the Hall mobility by orders of magnitude while, remarkably, the Hall concentration remains almost unchanged, suggesting that the Fermi level is pinned at a hole concentration near 1x1013 cm-2. A model for scattering by resonant scatterers is in good agreement with mobility measurements up to an ion fluence of 1x1014 cm-2.
Electrical-Equivalent van der Waals Gap for Two-Dimensional Bilayers

Vertical stacks of two-dimensional (2D) materials, separated by the van der Waals gap and held together by the van der Waals forces, are immensely promising for a plethora of nanotechnological applications. Charge control in these stacks may be modeled using either a simple electrostatics approach or a detailed atomistic one. In this paper, we compare these approaches for a gated 2D transition metal dichalcogenide bilayer and show that recently reported electrostatics-based models of this system give large errors in band energy compared to atomistic (Density Functional Theory) simulations. These errors are due to the tails of the ionic potentials that reduce the electrical-equivalent van der Waals gap between the 2D layers, and can be corrected by using the reduced gap in the electrostatic model. For a physical van der Waals gap (defined as the chalcogen to chalcogen distance) of 3 $\mathrm{\AA}$ in a 2D bilayer, the electrical-equivalent gap is less than 1 $\mathrm{\AA}$. For the example of band-to-band tunneling based ultra low-power transistors, this is seen to lead to errors of several hundred millivolts and more in the threshold voltage estimated from electrostatics.
E-Commerce Business Models and Search Engine Dependency

E-Commerce business models attracted a great deal of attention in the last years. An increasing number of bargains are realized via online transactions. However, some business models suffer distinctly under changes of search engine algorithms while others experience continuous stable traffic. This paper sheds light on the drivers of the unpunished e-commerce businesses based on a case-by-case analysis of 43 business models in the German Internet market. The analysis reveals that more stable business models are characterized by diversified customer arrivals which are obtained by a focused product management, multiple marketing channeling, freemium registration strategies and a subtle way to attract customer trust.
Individual and Group Brainstorming: Does the Question Matter?

The goal of this research was to test whether the kind of question that is used to prompt brainstorming differentially affects individual and group idea generation performance. More specifically, it was examined if prompts that require brainstormers to generate alternate uses for common objects (e.g., other uses for cars) foster more benefits from collaborative ideation than prompts to generate improvements for an object, place, or process (e.g., ways to improve cars). These hypotheses were tested in two experiments using electronic idea exchanges. In Experiment 1, individuals generated ideas about either alternate uses or potential improvements for cars, SUVs, or vans. In Experiment 2, participants brainstormed in response to one of these two prompts in either an interactive group setting (exchanging ideas with two others) or individually (no idea sharing). The results of both experiments showed that alternate uses and improvements prompts indeed differentially affected ideational performance in terms of both idea quantity and quality. The results were also consistent with the well documented “process loss” on the improvements prompt, but the gap between interacting and nominal groups was closed on the alternate uses prompt. Implications for research and practice are discussed.

Metodologia para Identificação de Glaucoma em Imagens de Retina

Glaucoma é uma doença que danifica o nervo óptico. Ela é consi- derada a segunda principal causa de cegueira no mundo. Vários sistemas de diagnóstico automático têm sido propostos. No entanto, esses sistemas não fo- ram capazes de lidar com uma grande diversidade de imagens. Portanto, tais métodos não são viáveis para uso em programas de triagem. Realizamos um ex- tenso estudo para definir o melhor conjunto de atributos para a representação da imagem. No total, avaliamos 16.469 caracterı́sticas. Nossa abordagem de detecção de glaucoma usa descritores de textura e Redes Neurais Convolucio- nais (CNNs). Avaliamos nossa proposta em um total de 873 imagens de quatro bancos de dados públicos e concluı́mos que a junção da GLCM e CNNs pré- treinadas juntamente com o uso do classificador Random Forest são promisso- res na detecção desta patologia, obtendo uma acurácia de 93,35% e um ı́ndice Kappa considerado Excelente.
Sustainable marketing communication strategies of Russian companies under the import substitution policy

The sanction standoff between Russia and the West opened up new opportunities for Russian food manufacturers. A new import substitution policy declared by the government restricted the access of the leading foreign countries to the market and unlocked a potential for internal development. Russian producers spotted new niches in the food market. There exist numerous obstacles to assimilating new market prospects: organizational (logistics, infrastructure, etc.), investment, legal, economic, etc. The paper underlines that the problem of enhancing the effectiveness of food companies' marketing policy in the context of import substitution is among the most formidable challenges. The article generalizes the problems of implementing the marketing policy of Russian enterprises. It reviews the core findings of the research studies on exploring consumers' attitude towards Russian and foreign-made food products. The author formulates recommendations about executing sustainable marketing communication strategies of Russian companies under import substitution.
Extended methodology for determining wetting properties of porous media

Because most methods for assessing the wettability of porous materials are restricted in their applicability, we developed two new methods for measuring contact angles and particle surface energy. The proposed methods (the Wilhelmy plate method (WPM) and the modified capillary rise method (MCRM)) were tested on 24 soils. For comparison, the water drop penetration time test (WDPTT) and the sessile drop method (SDM) were also applied. It was found that advancing contact angles, measured either with WPM or MCRM, agreed well in the range of 0° to 142°. Sessile drop contact angles were within the domain enclosed by the range of advancing and receding contact angles as determined with WPM. WDPTT, however, was only sensitive in the narrow range of 85° to 115°. We conclude that both WPM and MCRM are reliable methods for determining contact angles and particle surface energy over a wide range of porous material wettabilities.
Equilibrium Point for a Stakeholder Management Strategy in Crisis Episodes: the Case of a Crisis in a Food Processing Plant

The aim of this paper is to shed light on the way organizations that collaborate in multi-stakeholder networks organize their crisis management readiness. It argues that crisis management practices differ significantly based on whether or not organizations are supply or demand over-dependent. In equilibrium between demand and supply, an organization is able to rely on non-linear connectedness and interdependence to foster relationships in the supply chain during a crisis. In this paper, we analyze the case of a food safety crisis that occurred in 2008 at a Canadian-based processing plant and challenge the current conventions. Finally, conclusions concerning the implementation of the framework together with limitations and future research directions are presented.
Silencing of estrogen receptor β promotes the invasion and migration of osteosarcoma cells through activating Wnt signaling pathway

Purpose This study aimed to evaluate the specific roles of estrogen receptor β (ERβ) on the invasion and migration of osteosarcoma (OS) cells and explore the regulatory mechanisms relating with Wnt signaling pathway. Methods The expression of ERβ was detected in human OS tissues by quantitative real-time PCR and immunohistochemistry. U2-OS cells were transfected with siRNA-ERβ (si-ERβ) to downregulate ERβ and treated with FH535 to inhibit Wnt signaling. The migration and invasion ability was detected by scratch and transwell assay, respectively. The expression of β-catenin, MMP-7, and MMP-9 was detected by Western blot. Subcutaneous tumor-bearing model was established by injection of U2-OS cells into mice, and the tumor volumes were measured. Orthotopic transplantation model was established by transplantation of tumor tissues into the liver of mice, and the metastatic tumors were counted. Results ERβ was downregulated in human OS tissues and U2-OS cells. The transfection of si-ERβ significantly increased the scratch healing rate; the number of invasion cells; and the expression of β-catenin, MMP-7, and MMP-9 in U2-OS cells. The injection of si-ERβ-transfected U2-OS cells into mice significantly increased the subcutaneous tumor volume; the expression of β-catenin, MMP-7, and MMP-9; and the number of metastatic tumors in liver tissues. The promoting effects of si-ERβ on the invasion and migration of U2-OS cells were significantly reversed by FH535 in vitro and in vivo. Conclusion Silencing of ERβ promotes the invasion and migration of OS cells via activating Wnt signaling pathway.

Masculinity in Soccer As a Community of Practice by Situated Learning Approach

An attempt was made to understand how masculinity is learned by members of the soccer community of practice by situated learning approach and thus the transforming of soccer into a masculine field in this study. The conceptual framework of the study is based on both Lave and Wenger’s conceptualization of community of practice and Connell’s conceptualization of hegemonic masculinity. The findings of the study indicate that “winning” and “violence for winning” are the shared repertoire of members of the soccer community of practice and there is a mutual engagement in those concepts among members. In conclusion, in this study, it was observed that masculinity is reproduced by learning and undertaking violence practices in the soccer community of practice and this contributes to the recognition of soccer as a male profession.
Application of Chemically Modified and Unmodified Waste Biological Sorbents in Treatment of Wastewater

Protein wastes (feathers, goat hair) and cellulosic wastes (corn cob, coconut husks) were collected and washed with detergent solution, thoroughly rinsed and sun dried for 2 days before drying in an oven, and then ground. One-half of ground material was carbonized at a maximum temperature of 500°C after mixing with H2SO4. The carbonized parts were pulverized; both carbonized and uncarbonized sorbents were sieved into two particle sizes of 325 and 625 μm using mechanical sieve. Sorbents of a given particle size were packed into glass column.Then, textile wastewater that had its physicochemical parameters previously determined was eluted into each glass column and a contact time of 60 and 120 mins was allowed before analysis. Results showed 48.15–99.98 percentage reduction of NO3−, EC, Cl−, BOD, COD, DO, TSS, and TDS, 34.67–99.93 percentage reduction of NO3−, EC, Cl−, BOD, COD, DO, TSS, and TDS, 52.83–97.95 percentage reduction of Pb2
Exploiting SIMD Asymmetry in ARM-to-x86 Dynamic Binary Translation

Single instruction multiple data (SIMD) has been adopted for decades because of its superior performance and power efficiency. The SIMD capability (i.e., width, number of registers, and advanced instructions) has diverged rapidly on different SIMD instruction-set architectures (ISAs). Therefore, migrating existing applications to another host ISA that has fewer but longer SIMD registers and more advanced instructions raises the issues of asymmetric SIMD capability. To date, this issue has been overlooked and the host SIMD capability is underutilized, resulting in suboptimal performance. In this article, we present a novel binary translation technique called spill-aware superword level parallelism (saSLP), which combines short ARMv8 instructions and registers in the guest binaries to exploit the x86 AVX2 host’s parallelism, register capacity, and gather instructions. Our experiment results show that saSLP improves the performance by 1.6× (2.3×) across a number of benchmarks and reduces spilling by 97% (99%) for ARMv8 to x86 AVX2 (AVX-512) translation. Furthermore, with AVX2 (AVX-512) gather instructions, saSLP speeds up several data-irregular applications that cannot be vectorized on ARMv8 NEON by up to 3.9× (4.2×).
Antitussive Effect of Plantago lanceolata in Guinea Pigs

Background: Several therapeutic effects including antiasthma and dyspnea have been described for Plantago lanceolata. In the present study the antitussive effect of this plant was evaluated. Methods: The antitussive effects of aerosols of two different concentrations of Soxhlet and macerated ethanolic extracts, codeine and saline were tested by counting the number of coughs produced due to aerosol of citric acid 10 min after exposing the animal to aerosols of different solutions (n=8 for each solution). Results: The results showed significant reductions of cough number observed in the presence of both concentrations of Soxhlet and macerated extracts of Plantago lanceolata as compared to saline treated group (p<0.001). The reduced cough number observed in the presence of higher concentrations of extracts was not significantly different from that of lower concentrations of LP. Furthermore, there was no significant difference between the cough numbers observed in the presence of both concentrations of the extracts with that of codeine.
To end disease tomorrow, begin with trials today: Digital strategies for increased awareness of a clinical trials finder

Abstract Introduction: Individuals experiencing different medical conditions, as well as healthy volunteers, may often be interested in trial participation, and researchers similarly need to find participants to advance medical knowledge. The ResearchMatch (RM) Trials Today clinical trial searching tool leverages clinicaltrials.gov data to enable potential participants to look for trial opportunities relevant to their situation. To facilitate expanded use of this tool, we undertook a national digital public awareness campaign to increase awareness of Trials Today among members of the general public. Methods: The awareness campaign promoted Trials Today using Facebook and digital banner messages in 2017, encompassing nine cities across the USA. The digital strategy was complemented by print media in several outlets. We employed descriptive statistics to summarize campaign metrics and site usage data during the campaign. Results: The campaign was successful in increasing visits to Trials Today, with 142,303 sessions logged during its run, as compared to pre-campaign data indicating 104,688 total sessions during the entire 2-year period since the site’s inception. The city-specific click-through rate for all digital impressions, combining Facebook and banner messaging, ranged from 0.50% to 1.09%, resulting in a cost-per-click range of $0.69–$1.15. In addition, visitors conducted 29,697 searches and viewed individual trial records 173,512 times. Conclusion: The public awareness campaign was successful in increasing use of the RM Trials Today clinical trial searching tool. Our findings support the value of digital media messaging as a cost-effective vehicle for promoting clinical trial awareness, especially for chronic ailments.
Using Generative Models to Simulate Cosmogenic Radiation

We introduce HAWCgen, a set of deep generative neural network models, which are designed to supplement, or in some cases replace, parts of the simulation pipeline for the High Altitude Water Cherenkov (HAWC) observatory. We show that simple deep generative models replicate sampling of the reconstruction at a near arbitrary speedup compared to the current simulation. Furthermore, we show that generative models can offer a replacement to the detector simulation at a comparable rate and quality to current methods. This work was done as part of an undergraduate summer intern project at NVIDIA during the month of June, 2018.
The usefulness of a new TOBEC instrument (ACAN) for investigating body composition in small mammals

Estimates of water mass, lean body mass (LBM) and fat content based on total body electrical conductivity (TOBEC) measured with ACAN-2 were compared with direct measurements of carcass composition in two species of rodents: the laboratory mouse (n=20) and the bank vole (n=14). There was a strong linear relation relation between ACAN readings and lean mass or water mass. Body temperature did not affected the results, but the readings were dependent on the species and sex of the individuals. That could be due to differences in the body shape. The accuracy of predicting an average LBM or water mass was very high (1.5%), but the errors for predicting individual values were larger (8.5%). The predicted fat content values have identical confidence intervals as that for LBM. However, the relative error for prediction of the amount of fat was higher, becouse the mass of fat was much smaller than LBM.
