description: Thermal conduction in the intracluster medium has been proposed as a possible heating mechanism for offsetting central cooling losses in rich clusters of galaxies. In this study, we introduce a new formalism to model conduction in a diffuse ionised plasma using smoothed particle hydrodynamics (SPH), and we implement it in the parallel TreePM/SPH-code GADGET-2. We consider only isotropic conduction and assume that magnetic suppression can be described in terms of an effective conductivity, taken as a fixed fraction of the temperature-dependent Spitzer rate. We also account for saturation effects in low-density gas. Our formulation manifestly conserves thermal energy even for individual and adaptive timesteps, and is stable in the presence of small-scale temperature noise. This allows us to evolve the thermal diffusion equation with an explicit time integration scheme along with the ordinary hydrodynamics. We use a series of simple test problems to demonstrate the robustness and accuracy of our method. We then apply our code to spherically symmetric realizations of clusters, constructed under the assumptions of hydrostatic equilibrium and a local balance between conduction and radiative cooling. While we confirm that conduction can efficiently suppress cooling flows for an extended period of time in these isolated systems, we do not find a similarly strong effect in a first set of clusters formed in self-consistent cosmological simulations. However, their temperature profiles are significantly altered by conduction, as is the X-ray luminosity.

description: Corn (Zea mays L.) is an important staple food crop for millions of people in many developing countries. Its production levels in developing countries, are lower than in developed countries in part to planting methods that involve hand dropping of multiple seeds per hill assisted with tools such as hand hoes, cutlasses and/or dibblers (Stick Seeder Planter (SSP)). Researchers at Oklahoma State University (OSU) developed the Greenseeder Hand Planter (GHP) which is hypothesized to reduce optimal seeding rates because it places one seed per hill and potentially reduces long term health risks because it does not require using bare hands to drop the pesticide treated seeds. The objective of this research was to determine the economics of using the GHP relative to the conventional SSP. Data from field trials were obtained. A linear mixed effects model was used. Partial budgets were used to determine the quantity of seed savings, the amount of labor, and the increase in corn yield that would be required for the GHP to be an economically viable alternative to the SSP. Results suggest that a GHP expected to be used to plant 3 hectares per year that costs $50 would be required to increase corn yields by 0.028 Mg per hectare or save about 9,022 seeds per hectare (12.19% less) to equal expected net returns from the SSP. Alternatively, it would be required to reduce labor man-days by 1.933 for a farmer to breakeven relative to the SSP. Additional research would be required to determine differences in farmer health consequences of the GHP relative to the SSP from the reduction in the level of contact with pesticide treated seed.

description: This paper addresses the demand and challenges for local foods and focuses on the marketing strategies for retail promotion. While federal and state government make efforts to promote local food purchases and consumption at the farm level, local foods face significant distribution challenges in grocers, especially in larger chains. Limited shelf space and high pricing by retailers impede consumers’ purchase and result in weak competitiveness for local brands. Therefore, it is essential for local producers and “buy local” programs to understand what types of promotion and marketing strategies might be more effective in stimulating demand in retail outlets. Using 2006-2011 Nielsen Retail Scanner data in the United States, we estimate a random coefficient discrete choice model to determine the effects of nutritional characteristics, price, packaging, and the distribution strategies on the consumers’ choice to purchase locally branded milk. We restrict our analysis to the top 7 national brands, top 9 local brands, and private labels. Results show even though, on average, consumers prefer less local milk brands than private label brands, income, and other unobservable factors significantly influence consumer-specific tastes. Simulations show that a price cut, one-gallon package offering, and expanding distribution channels can significantly stimulate the demand for locally branded milk.
title: Analysis of Corporate Social Responsibility in the Egyptian Banking Sector
Creators: name: Hawas, Amira Mohamed Refaat
Publisher: name: The Open University

description: Due to the increasing pressure on multinational corporations (MNCs) to take responsibility for their business operations, many large corporations have started to address the concept of corporate social responsibility (CSR). Accordingly, corporate social disclosure, that is the communication of an organisation’s social and environmental impact through the annual report or similar medium, is an increasingly important issue. The purpose of this thesis is to explore how multinational banks working in Egypt choose to communicate their CSR activities to different stakeholders, and to compare it with local banks. Content analysis has been used to analyse both the annual reports and web pages of both multinational and local banks. CSR was classified into five themes (environmental related, community related, employee related, customer related and investor related). The results of the empirical work show that there is CSR disclosure in the banking sector in Egypt at both a local and multinational level; all of the banks disclosed some information related to different CSR categories and it was positive information. The results also showed that this social disclosure in the Egyptian banking sector was inadequate and there is still a long way to go. The social information disclosed was far less than leading banks in developed countries. Also, the study indicated that a greater amount of information was provided on the website than in the annual report, especially within multinational banks. These results could be attributed to the voluntary nature of the reporting regime in Egypt.
Origin of positive magnetoresistance in small-amplitude unidirectional lateral superlattices

description: We report quantitative analysis of positive magnetoresistance (PMR) for unidirectional-lateral-superlattice samples with relatively small periods (a=92-184 nm) and modulation amplitudes (V_0=0.015-0.25 meV). By comparing observed PMR's with ones calculated using experimentally obtained mobilities, quantum mobilities, and V_0's, it is shown that contribution from streaming orbits (SO) accounts for only small fraction of the total PMR. For small V_0, the limiting magnetic field B_e of SO can be identified as an inflection point of the magnetoresistance trace. The major part of PMR is ascribed to drift velocity arising from incompleted cyclotron orbits obstructed by scatterings.

description: Three-dimensional structure of complex (dusty) plasmas was investigated under long-term microgravity conditions in the International-Space-Station-based Plasmakristall-4 facility. The microparticle suspensions were confined in a polarity-switched dc discharge. The experimental results were compared to the results of the molecular dynamics simulations with the interparticle interaction potential represented as a superposition of isotropic Yukawa and anisotropic quadrupole terms. Both simulated and experimental data exhibited qualitatively similar structural features indicating the bulk liquid-like order with the inclusion of solid-like strings aligned with the axial electric field. Individual strings were identified and their size spectrum was calculated. The decay rate of the size spectrum was found to decrease with the enhancement of string-like structural features.

description: Crop diversification is a climate smart agricultural technique which helps improve resilience for farmers in the face of volatile weather due to climate change. Previous research on its effect on technical efficiency shows contrasting results (positive and negative effects). Other literature show that crop diversification has a positive impact on income variability. Is it possible that choosing crop diversification involves a tradeoff between efficiency and resilience (income variability) for rural smallholder farmers? It is likely that merging these two separate sets of previous literature, one on the effects of crop diversification on technical efficiency, and another on its effect on income variability, can provide valuable insights on the decision making process faced by a farmer considering to adopt crop diversification. So essentially, the question we try to answer in this study is what is the effect of crop diversification on technical efficiency and income variability on the same farm household of northern Ghana? Without addressing this question, policy makers cannot tell for sure if crop diversification is a good CSA option for their farmers, and if it is, they still may not know how to promote its adoption effectively. To answer our research question, we use the Agricultural production data from northern Ghana and employ a Cobb Douglas stochastic input distance function for efficiency, and ordinary least squares for income variability. The results show evidence against ‘tradeoff’. Crop diversification significantly improves efficiency and reduces income variability in northern Ghana so farmers do not have to give up efficiency for income stability or vice versa. Thus crop diversification is an ideal CSA strategy for promoting agricultural growth and resilience in northern Ghana. The data we use in this study has a maximum three crops, so our results cannot be generalized to farmers who grow more than three crops.

description: Graph convolutional neural networks, which learn aggregations over neighbor nodes, have achieved great performance in node classification tasks. However, recent studies reported that such graph convolutional node classifier can be deceived by adversarial perturbations on graphs. Abusing graph convolutions, a node's classification result can be influenced by poisoning its neighbors. Given an attributed graph and a node classifier, how can we evaluate robustness against such indirect adversarial attacks? Can we generate strong adversarial perturbations which are effective on not only one-hop neighbors, but more far from the target? In this paper, we demonstrate that the node classifier can be deceived with high-confidence by poisoning just a single node even two-hops or more far from the target. Towards achieving the attack, we propose a new approach which searches smaller perturbations on just a single node far from the target. In our experiments, our proposed method shows 99% attack success rate within two-hops from the target in two datasets. We also demonstrate that m-layer graph convolutional neural networks have chance to be deceived by our indirect attack within m-hop neighbors. The proposed attack can be used as a benchmark in future defense attempts to develop graph convolutional neural networks with having adversary robustness.

description: The ellipsoidally symmetric extension of Buda-Lund hydrodynamic model is shown here to yield a natural description of the pseudorapidity dependence of the elliptic flow $v_2(η)$, as determined recently by the PHOBOS experiment for Au+Au collisions at $\sqrt{s_{NN}} = 130$ and 200 GeV. With the same set of parameters, the Buda-Lund model describes also the transverse momentum dependence of $v_2$ of identified particles at mid-rapidity. The results confirm the indication for quark deconfinement in Au+Au collisions at RHIC, obtained from a successful Buda-Lund hydro model fit to the single particle spectra and two-particle correlation data, as measured by the BRAHMS, PHOBOS, PHENIX and STAR collaborations.

description: Clarence Cannon Dam and Mark Twain Lake were built to provide Northeast Missouri with the benefits of hydropower, flood control, recreation, fish and wildlife conservation and water supply. In planning for future growth, 20,000 acre-feet of water storage was allocated for water supply. However, northeast Missouri region did not experience the anticipated population growth and only a third of the allocated water is currently used for water supply. As per the contract signed in 1988, the State of Missouri makes payments on capital costs of construction of the dam/reservoir, interest on capital, operation and maintenance. In addition, if not all of the 20,000 acre-feet of water is not put to use by 2038, the State of Missouri is due to pay $11.3 million to the U.S. Army Corps of Engineers. The purpose of this study is to estimate the future water demand, optimize water use as well as financial resources and make policy recommendations to the decision makers on resource allocation in Missouri. The results indicate savings to Missouri which can be used to address water resource needs in other parts of the State.

description: Glaucoma causes an irreversible damage to retinal nerve fibers which results in vision loss, if undetected in early stage. Therefore, diagnosis of glaucoma in its early stage may prevent further vision loss. In this paper, we propose a convolutional neural network (CNN) based approach for automated glaucoma diagnosis by employing retinal fundus images. This approach employs transfer learning technique and local binary pattern (LBP) based data augmentation. In the proposed approach, we employ Alexnet as a pre-trained CNN model which is used for transfer learning. Initially, the proposed approach divides the fundus image dataset into training and testing data. Further, the color fundus images in training and testing data are separated into red (R), green (G), and blue (B) channels. Additionally, the LBP-based data augmentation is performed on training data. Specifically, we compute LPBs for each of the channel. Finally, the augmented training data is used to train the CNN model via transfer learning. In testing stage, the R, G, and B channels of test image are fed to the trained CNN model which generates 3 decisions. We employ a decision level fusion technique to combine the decisions obtained from the trained CNN model. The experimental evaluation of the proposed approach on the public RIM-ONE fundus image database, achieves state-of-the-art performance for glaucoma diagnosis.

description: The arising of central extensions is discussed in two contexts. At first classical counterparts of quantum anomalies (deserving being named as "classical anomalies") are associated with a peculiar subclass of the non-equivariant maps. Further, the notion of "residual symmetry" for theories formulated in given non-vanishing EM backgrounds is introduced. It is pointed out that this is a Lie-algebraic, model-independent, concept.

description: The massive integration of power electronics-based renewable energy sources has profoundly changed the electrical grid. In this scenario, the smart transformer, which is a solid-state transformer with advanced control and communication features, has been proposed as one of the solutions to offer new grid services, while mitigating electrical grid issues, including voltage/frequency disturbance, harmonics, voltage instability, and to pave the way towards dc grids. The commonly proposed topology for ST is the three-stage ac-dc-dc-ac converter, due to the availability of the dc link at both medium- and low-voltage sides. The control design usually relies on the well-known techniques of pole/zero placement and each conversion stage is considered separately. This paper proposes a unified predictive control of the three stages of the ST that allows to control all the variables with a single cost function. Simulation results show the effectiveness of the proposed solution in guaranteeing excellent current tracking performance and good disturbance rejection.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: We introduce a kind of converse of Pompeiu's theorem. Fix an equilateral triangle $\triangle A_0B_0C_0$, then for any triangle $\triangle ABC$ there is a unique point $P$ inside the circumcircle $Γ_0$ of $\triangle A_0B_0C_0$ such that a triangle with edge lengths $PA_0, PB_0$, and $PC_0$ is similar to $\triangle ABC$. It follows that an open disc inside $Γ_0$ can be considered as a moduli space of similarity classes of triangles. We show that it is essentially equivalent to another moduli space based on a shape function of triangles which has been used in preceding studies.

description: Four transits of the planet orbiting the star HD209458 were observed with the STIS spectrograph on board HST. The wavelength domain (1180-1710A) includes HI as well as CI, CII, CIV, NV, OI, SI, SiII, SiIII and SiIV lines. During the transits, absorptions are detected in HI, OI and CII (5+/-2%, 13+/-4.5% and 7.5+/-3.5%, respectively). No absorptions are detected for other lines. The 5% mean absorption over the whole HI Lyman alpha line is consistent with the previous detection at higher resolution (Vidal-Madjar et al. 2003). The absorption depths in OI and CII show that oxygen and carbon are present in the extended upper atmosphere of HD209458b. These species must be carried out up to the Roche lobe and beyond, most likely in a state of hydrodynamic escape.

description: We implement inflation in a supersymmetric SU(5) model with U(1) R-symmetry such that the cosmic microwave anisotropy $δT/T$ is proportional to $(M/M_{\rm Planck})^2$, where $M\sim M_{GUT}=2-3\times 10^{16}$ GeV, the SU(5) breaking scale, and $M_{\rm Planck}=2.4\times 10^{19}$ GeV. The presence of a global $U(1)_X$ symmetry, spontaneously broken also at scale $M_{GUT}$, provides an upper bound $M_{GUT}^2/M_{\rm Planck}\sim 10^{14}$ GeV on the masses of SU(5) singlet right handed neutrinos, which explains the mass scale associated with atmospheric neutrino oscillations. The SU(5) monopoles and $U(1)_X$ cosmic strings are inflated away. Although the doublet-triplet splitting requires fine-tuning, the MSSM $μ$ problem is resolved and dimension five proton decay is strongly suppressed.

description: We propose a model of antibiotic diffusion through a bacterial biofilm when diffusion and/or absorption barriers develop in the biofilm. The idea of this model is: We deduce details of the diffusion process in a medium in which direct experimental study is difficult, based on probing diffusion in external regions. Since a biofilm has a gel-like consistency, we suppose that subdiffusion of particles in the biofilm may occur. To describe this process we use a fractional subdiffusion-absorption equation with an adjustable anomalous diffusion exponent. The boundary conditions at the boundaries of the biofilm are derived by means of a particle random walk model on a discrete lattice leading to an expression involving a fractional time derivative. We show that the temporal evolution of the total amount of substance that has diffused through the biofilm explicitly depends on whether there is antibiotic absorption in the biofilm. This fact is used to experimentally check for antibiotic absorption in the biofilm and if the biofilm parameters change over time. We propose a four-stage model of antibiotic diffusion in biofilm based on the mentioned above physical characteristics. The biological interpretation of the stages, in particular their relation with the bacterial defence mechanisms, is discussed. Theoretical results are compared with empirical results of ciprofloxacin diffusion through Pseudomonas aeruginosa biofilm, and ciprofloxacin and gentamicin diffusion through Proteus mirabilis biofilm.

description: Coalescence of intermediate-mass black holes (IMBHs) as a result of the migration toward galactic centers via dynamical friction may contribute to the formation of supermassive BHs. Here we reinvestigate the gaseous dynamical friction, which was claimed to be inefficient with radiative feedback from BHs in literature, by performing 3D radiation-hydrodynamics simulations that solve the flow structure in the vicinity of BHs. We consider a $10^4~M_\odot$ BH moving at the velocity $V_{\rm flow}$ through the homogeneous medium with metallicity $Z$ in the range of $0-0.1~Z_\odot$ and density $n_{\infty}$. We show that, if $n_{\infty} \lesssim 10^{6}~{\rm cm^{-3}}$ and $V_{\rm flow} \lesssim 60~{\rm km~s^{-1}}$, the BH is accelerated forward because of the gravitational pull from a dense shell ahead of an ionized bubble around the BH, regardless of the value of $Z$. If $n_{\infty} \gtrsim 10^{6}~{\rm cm^{-3}}$, however, our simulation shows the opposite result. The ionized bubble and associating shell temporarily appear, but immediately go downstream with significant ram pressure of the flow. They eventually converge into a massive downstream wake, which gravitationally drags the BH backward. The BH decelerates over the timescale of $\sim 0.01$~Myr, much shorter than the dynamical timescale in galactic disks. Our results suggest that IMBHs that encounter the dense clouds rapidly migrate toward galactic centers, where they possibly coalescence with others.

description: Concerns about cocoa production in Africa at the expense of forests, biodiversity and its effects on sustainability necessitate the investigation of price premiums to incentivize cocoa producers to abandon the practices of plantation style cocoa for more sustainable practices shaded cocoa. Thus, this study first employs a multiple regression on a sample of 2,076 Ghanaian cocoa households over five cocoa growing seasons (2002, 2004, 2006, 2008, and 2010), to estimate the yield difference among three varieties of cocoa. These yield differentials in addition to published yield curves are then used to simulate variety specific yield curves under shaded and unshaded cocoa production. These yield curves in addition to cost curves, are then used to estimate the price premium that reflects the opportunity cost of cultivating shaded cocoa. Results indicates that the mean price premium of approximately 4.95% currently offered by third-party production certification schemes (e.g. UTZ Certified) for biodiversity friendly cocoa are well below this study’s price premium of 20.5%. Estimating the opportunity cost of shaded cocoa production is important to producers to determine whether growing cocoa under shade is sufficiently profitable. For manufacturers and consumers, these premiums indicate the cost needed to secure a supply of sustainably produced cocoa

description: Microlensing is the only known direct method to measure the masses of stars that lack visible companions. In terms of microlensing observables, the mass is given by M=(c^2/4G)\tilde r_E θ_E and so requires the measurement of both the angular Einstein radius, θ_E, and the projected Einstein radius, \tilde r_E. Simultaneous measurement of these two parameters is extremely rare. Here we analyze OGLE-2003-BLG-238, a spectacularly bright (I_min=10.3), high-magnification (A_max = 170) microlensing event. Pronounced finite source effects permit a measurement of θ_E = 650 uas. Although the timescale of the event is only t_E = 38 days, one can still obtain weak constraints on the microlens parallax: 4.4 AU < \tilde r_E < 18 AU at the 1 σlevel. Together these two parameter measurements yield a range for the lens mass of 0.36 M_sun < M < 1.48 M_sun. As was the case for MACHO-LMC-5, the only other single star (apart from the Sun) whose mass has been determined from its gravitational effects, this estimate is rather crude. It does, however, demonstrate the viability of the technique. We also discuss future prospects for single-lens mass measurements.

description: Automated prostate segmentation in MRI is highly demanded for computer-assisted diagnosis. Recently, a variety of deep learning methods have achieved remarkable progress in this task, usually relying on large amounts of training data. Due to the nature of scarcity for medical images, it is important to effectively aggregate data from multiple sites for robust model training, to alleviate the insufficiency of single-site samples. However, the prostate MRIs from different sites present heterogeneity due to the differences in scanners and imaging protocols, raising challenges for effective ways of aggregating multi-site data for network training. In this paper, we propose a novel multi-site network (MS-Net) for improving prostate segmentation by learning robust representations, leveraging multiple sources of data. To compensate for the inter-site heterogeneity of different MRI datasets, we develop Domain-Specific Batch Normalization layers in the network backbone, enabling the network to estimate statistics and perform feature normalization for each site separately. Considering the difficulty of capturing the shared knowledge from multiple datasets, a novel learning paradigm, i.e., Multi-site-guided Knowledge Transfer, is proposed to enhance the kernels to extract more generic representations from multi-site data. Extensive experiments on three heterogeneous prostate MRI datasets demonstrate that our MS-Net improves the performance across all datasets consistently, and outperforms state-of-the-art methods for multi-site learning.

description: Finescale probes of many complex electronic materials have revealed a non-uniform nanoworld of sign-varying textures in strain, charge and magnetization, forming meandering ribbons, stripe segments or droplets. We introduce and simulate a Ginzburg-Landau model for a structural transition, with strains coupling to charge and magnetization. Charge doping acts as a local stress that deforms surrounding unit cells without generating defects. This seemingly innocuous constraint of elastic `compatibility', in fact induces crucial anisotropic long-range forces of unit-cell discrete symmetry, that interweave opposite-sign competing strains to produce polaronic elasto-magnetic textures in the composite variables. Simulations with random local doping below the solid-solid transformation temperature reveal rich multiscale texturing from induced elastic fields: nanoscale phase separation, mesoscale intrinsic inhomogeneities, textural cross-coupling to external stress and magnetic field, and temperature-dependent percolation. We describe how this composite textured polaron concept can be valuable for doped manganites, cuprates and other complex electronic materials.
