Smoothed Particle Magnetohydrodynamics I. Algorithms and tests in one dimension

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In this paper we show how the Smoothed Particle Hydrodynamics (SPH) equations for ideal magnetohydrodynamics (MHD) can be written in conservation form with the positivity of the dissipation guaranteed. We call the resulting algorithm Smoothed Particle Magnetohydrodynamics (SPMHD). The equations appear to be accurate, robust and easy to apply and do not suffer from the instabilities known to exist previously in formulations of the SPMHD equations. In addition we formulate our MHD equations such that errors associated with non-zero divergence of the magnetic field are naturally propagated by the flow and should therefore remain small. In this and a companion paper (Price and Monaghan 2003b) we present a wide range of numerical tests in one dimension to show that the algorithm gives very good results for one dimensional flows in both adiabatic and isothermal MHD. For the one dimensional tests the field structure is either two or three dimensional. The algorithm has many astrophysical applications and is particularly suited to star formation problems.

description: Innovation in agricultural biotechnology seed products can be characterized as a non-drastic innovative process with product differentiation. We model this innovation and examine the pricing and purchase decisions for experimental use licensing. In equilibrium, a technologically advantaged firm will purchase a license, while a technologically disadvantaged firm will not. This is the case regardless of the order of pricing decisions.

description: Over 90% of U.S. corn and soybeans are planted with genetically modified (GM) seed varieties. We use a flexible, nonlinear functional form to investigate yield differences for corn, soybeans, and wheat between the United States and the European Union (which bans the use of GM technologies). U.S. corn and soybean yields increased relative to EU yields since the introduction of GM technologies. EU wheat yields (for which GM technologies are not commercially available in either region) continue to increase relative to the United States. Thus, the EU ban on GM technologies has likely increased the difference between corn and soybean yields between the two regions.

description: The process of structural relaxation in disordered solids subjected to repeated tension-compression loading is studied using molecular dynamics simulations. The binary glass is prepared by rapid cooling well below the glass transition temperature and then periodically strained at constant volume. We find that the amorphous system is relocated to progressively lower potential energy states during hundreds of cycles, and the energy levels become deeper upon approaching critical strain amplitude from below. The decrease in potential energy is associated with collective nonaffine rearrangements of atoms, and their rescaled probability distribution becomes independent of the cycle number at sufficiently large time intervals. It is also shown that yielding during startup shear deformation occurs at larger values of the stress overshoot in samples that were cyclically loaded at higher strain amplitudes. These results might be useful for mechanical processing of amorphous alloys in order to reduce their energy and increase chemical resistivity and resistance to crystallization.

title: A MODEL OF GEOGRAPHICAL CHANGE ILLUSTRATED BY SELECTED CHANGES IN BUCKS IN GENERAL, AND FENNY STRATFORD IN PARTICULAR. 1760-1850.
Creators: name: Newbury, Paul A
Publisher: name: The Open University
Year: 1977

description: The aim is to evolve a model which will illustrate the integral processes of geographical change, one capable of application to various situations. It is necessary to give adequate consideration to changes of spatial significance, as well as to the basic dimension of change in time. It is also important to take into account the complementary contributions to change from economic, social, and political forces on one hand, and man as a thinking and active agent of change on the other. Towards these ends the initial step has been to represent the stochastic model in diagrammatical form for more convenient manipulation. It has been tested against information for Buckinghamshire, and particularly Fenny Stratford, I76O-I85O. This small market town experienced an interesting and varied selection of changes which also affected Buckinghamshire as a whole, and its adequate documentation was also a recommendation. In order to simplify the model for practical purposes only four out of many interrelated aspects of change have been considered:- population, agricultural land holding and land-use, settlement, communications and trade, and class structures. In addition change is represented as operating through consecutive cycles of change within prescribed units of time. In reality such repetitive cycles of change would move towards completion at different rates, instead of operating concurrently within such prescribed units of time. Despite simplification, the model demonstrates the way external economic pressures modified land-holding patterns, which in turn modified social class structures and relations between classes; it also shows the Grand Junction Canal to have been the major influence upon Buckinghamshire's, particularly Fenny Stratford's, economic development at this period. It is hoped to develop the model towards increased authenticity and a wider range of application, through application to comparative studies elsewhere, in order to illustrate not only changes in these different situations, but the integral processes of geographical change themselves.

description: Here we present the discovery of 895 s-process-rich candidates from 454,180 giant stars observed by the Large Sky Area Multi-Object Fibre Spectroscopic Telescope (LAMOST) using a data-driven approach. This sample constitutes the largest number of s-process enhanced stars ever discovered. Our sample includes 187 s-process-rich candidates that are enhanced in both barium and strontium, 49 stars with significant barium enhancement only and 659 stars that show only a strontium enhancement. Most of the stars in our sample are in the range of effective temperature and log g typical of red giant branch (RGB) populations, which is consistent with our observational selection bias towards finding RGB stars. We estimate that only a small fraction (0.5 per cent) of binary configurations are favourable for s-process enriched stars. The majority of our s-process-rich candidates (95 per cent) show strong carbon enhancements, whereas only five candidates (less than 3 percent) show evidence of sodium enhancement. Our kinematic analysis reveals that 97 percent of our sample are disc stars, with the other 3 percent showing velocities consistent with the Galactic halo. The scaleheight of the disc is estimated to be zh=0.634kpc, comparable with values in the literature. A comparison with the yields from asymptotic giant branch (AGB) models suggests that the main neutron source responsible for the Ba and Sr enhancements is the 13C(alpha,n)16O reaction. We conclude that the s-process-rich candidates may have received their overabundances via mass transfer from a previous ABG companion with an initial mass in the range 1-3Msun.

description: Utilization of waste-derived materials for industrially pertinent chemical transformations is highly challenging and offers sustainable solution to waste management. Despite several difficulties in the manufacture of aryl iodides (AIs), which are the fundamental substrates in organic synthesis, we report here, an added oxidant/metal/catalyst/additive and problematic solvent-free versatile and straightforward protocol for the synthesis of AIs using molecular iodine (I2) in water extract of pomegranate ash (WEPA). These transformations were performed at room temperature (rt) and the reactions takes place in 5–20 min to give 83–99% yields of AIs. WEPA was characterized by using XPS, EDX, XRF, XRD, and FTIR analysis and a plausible mechanism has been established based on these analyses along with some control experiments. Further, the products were purified by recrystallization technique. This work with intrinsic sustainability, high substrate feasibility, utilization of biorenewable catalystytic media, ease of execution and separation of products, and added oxidant/catalyst/metal and additive-free conditions may become one among the forefront sustainable procedures in making AIs. The use of waste-derived WEPA as catalystytic media for this iodination is the novelty of this method and may be used these AIs for further in-process transformations (e.g. cross-couplings, nucleophilic reactions, etc.) to access fine chemicals.
Hidden Scaling in the Quantum Hall Metal-Insulator Transition

description: Scaling properties of the quantum Hall metal-insulator transition are severely affected by finite size effects in small systems. Surprisingly, despite the narrow spatial range where probability structure functions exhibit multifractal scaling, we clearly verify the existence of extended self-similarity -- a hidden infrared scaling phenomenon related to the peculiar form of the crossover at the onset of nonmultifractal behavior. As finite size effects get stronger for structure functions with negative orders, the parabolic approximation for the multifractal spectrum loses accuracy. However, by means of an extended self-similarity analysis, an improved evaluation of the multifractal exponents is attained for negative orders too, rendering them consistent with previous results, which rely on computations performed for considerably larger systems.

Anti-$k_T$ jet function at next-to-next-to-leading order

description: Jets constructed via clustering algorithms (e.g., anti-$k_T$, soft-drop) have been proposed for many precision measurements, such as the strong coupling $\alpha_s$ and the nucleon intrinsic dynamics. However, the theoretical accuracy is affected by missing QCD corrections at higher orders for the jet functions in the associated factorization theorems. Their calculation is complicated by the jet clustering procedure. In this work, we propose a method to evaluate jet functions at higher orders in QCD. The calculation involves the phase space sector decomposition with suitable soft subtractions. As a concrete example, we present the quark-jet function using the anti-$k_T$ algorithm with E-scheme recombination at next-to-next-to-leading order.

description: In this paper we show how a Lagrangian variational principle can be used to derive the SPMHD (smoothed particle magnetohydrodynamics) equations for ideal MHD. We also consider the effect of a variable smoothing length in the SPH kernels after which we demonstrate by numerical tests that the consistent treatment of terms relating to the gradient of the smoothing length in the SPMHD equations significantly improves the accuracy of the algorithm. Our results complement those obtained in a companion paper (Price and Monaghan 2003a, paper I) for non ideal MHD where artificial dissipative terms were included to handle shocks.

title: The microbial populations of the intertidal zone of two sandy beaches
Creators: name: Brown, Austin Ewing
Publisher: name: The Open University
Year: 1979

description: This study was based on an examination of the bacterial and fungal populations in the Intertidal zone of two sandy beaches. The two beaches were near Hartlepool, Cleveland, and one was selected as being heavily polluted by a major sewage outfall whilst the other appeared to be relatively unpolluted. Several physical and chemical characteristics of the two beaches were also assessed. The results show that there were resident populations of heterotrophic bacteria present in both beaches. These populations consisted principally of species of Pseudononas. Fungi were also isolated from both sites. Most of the genera recorded are normally regarded as terrestial. There was on inverse correlation between the numbers of bacteria and fungi in both beaches. No major qualitative or quantitative difference was found between the microbiology of the polluted and the non-polluted beach. Human faecal bacteria were not found in either sediment. Experiments carried out on the effects of adsorption in these intertidal sands emphasised the importance of this phenomenon in the microbial ecology of these substrates. Desiccation was shown to profoundly change the bacterial flora of sand but water loss was considered to be minimal in the zones subject to twice doily inundation.

description: A metal-free, atom-economy and simple work-up domino amination-Knoevenagel condensation approach to construct new coumarin analogous (4a-f and 8a-e) was described. Further, new formyl (5a,d-f) and nitro (9a,d-f) coumarin derivatives were synthesized via C-N coupling reaction of various cyclic secondary amines and 4-chloro-3-(formyl-/nitro)coumarins (1a,c), respectively. The confirmed compounds were screened for their in vitro anti-proliferative activity against KB-3-1, A549 and PC3 human cancer cell lines using resazurin cellular-based assay. Among them, coumarin derivatives 4e and 8e displayed the best anti-cervical cancer potency (KB-3-1) with IC50 values of 15.5 ± 3.54 and 21 ± 4.24 µM, respectively. Also, 4e showed the most promising cytotoxicity toward A549 with IC50 value of 12.94 ± 1.51 µM. As well, 9d presented a more significant impact of potency against PC3 with IC50 7.31 ± 0.48 µM. Moreover, 8d manifested selectivity against PC3 (IC50 = 20.16 ± 0.07 µM), while 8e was selective toward KB-3-1 cell line (IC50 = 21 ± 4.24 µM). Matching with docking profile, the enzymatic assay divulged that 8e is a dual potent single-digit nanomolar inhibitor of VEGFR-2 and EGFR with IC50 values of 24.67 nM and 31.6 nM that were almost equipotent to sorafenib (31.08 nM) and erlotinib (26.79 nM), respectively.

description: Motivated by a risk process with positive and negative premium rates, we consider a real-valued Markov additive process with finitely many background states. This additive process linearly increases or decreases while the background state is unchanged, and may have upward jumps at the transition instants of the background state. It is known that the hitting probabilities of this additive process at lower levels have a matrix exponential form. We here study the hitting probabilities at upper levels, which do not have a matrix exponential form in general. These probabilities give the ruin probabilities in the terminology of the risk process. Our major interests are in their analytic expressions and their asymptotic behavior when the hitting level goes to infinity under light tail conditions on the jump sizes. To derive those results, we use a certain duality on the hitting probabilities, which may have an independent interest because it does not need any Markovian assumption.

description: The European Space Agency's (ESA) Rosetta mission has returned a vast data set of measurements of the inner gas coma of comet 67P/Churyumov-Gerasimenko. These measurements have been used by different groups to determine the distribution of the gas sources at the nucleus surface. The solutions that have been found differ from each other substantially and illustrate the degeneracy of this issue. It is the aim of this work to explore the limitations that current gas models have in linking the coma measurements to the surface. In particular, we discuss the sensitivity of Rosetta's ROSINA/COPS, VIRTIS, and MIRO instruments to differentiate between vastly different spatial distributions of the gas emission from the surface. We have applied a state of the art 3D DSMC gas dynamics code to simulate the inner gas coma of different models that vary in the fraction of the surface that contains ice and in different sizes of active patches. These different distributions result in jet interactions that differ in their dynamical behaviour. We have found that ROSINA/COPS measurements by themselves cannot detect the differences in our models. While ROSINA/COPS measurements are important to constrain the regional inhomogeneities of the gas emission, they can by themselves not determine the surface emission distribution of the gas sources to a spatial accuracy of better than a few hundred metres (400 m). Any solutions fitting the ROSINA/COPS measurements is hence fundamentally degenerate, be it through a forward or inverse model. Only other instruments with complementary measurements can potentially lift this degeneracy as we show here for VIRTIS and MIRO. Finally, as a by-product, we have explored the effect of our activity distributions on lateral flow at the surface that may be responsible for some of the observed aeolian features.

description: Humans like to find things out. They naturally ask questions and explore the world around them. One observes such behavior already in neonatal infants. Inspiration to further develop such exploratory behavior, the quest to understand and do so deeply, is stimulated by different things, depending on the environment in which one is born and grows up. We thus do not all have the same chances to be inspired. However, there is one exception. Throughout human history humans around the world have stood in awe of the wonders of the sky, the universe. This is a source of inspiration that unites us all. The above considerations and possibly other ones have led to the Universe Awareness (UNAWE) project, which focuses specifically on underprivileged children between the ages of four and ten. Universe Awareness (UNAWE) uses the beauty and grandeur of the Universe to encourage young children, particularly those from an underprivileged background, to have an interest in science and technology and foster their sense of global citizenship from the earliest age.

description: Recent oil spills causing pollution in oceans and other bodies of water require sorbents that are both cost-effective and eco-friendly. Novel magnetic silica sorbent materials (MSS) have been synthesized using ash from rice husks or sugarcane bagasse and red dust, a waste generated in the steel industry. The designed MSS exhibited a definite response to external magnetic fields. The MSS, based on rice husk ash and bagasse ash, showed oil loading capacities of 1.93 and 2.09 times their weight, respectively, and also exhibited recyclability. The MSS were also functionalized to make them oleophilic and hydrophobic using sodium oleate. These functionalized rice husk ash and bagasse ash-based MSS showed oil loading capacities of 3.22 and 2.69 times their weight, respectively. Magnetic separation provided a convenient method for the removal of magnetizable particles by applying an appropriate external magnetic field. The MSS at the end of their utilization cycles were successfully incorporated into geopolymeric material, enabling the process to be zero waste and to achieve the overall goal of finding a green approach to use these wastes after oil spillage cleanup.

description: The lifetime differences of bottom hadrons are known to be properly explained within the framework of heavy quark effective field theory(HQEFT) of QCD via the inverse expansion of the dressed heavy quark mass. In general, the spectrum around the endpoint region is not well behaved due to the invalidity of $1/m_Q$ expansion near the endpoint. The curve fitting method is adopted to treat the endpoint behavior. It turns out that the endpoint effects are truly small and the explanation on the lifetime differences in the HQEFT of QCD is then well justified. The inclusion of the endpoint effects makes the prediction on the lifetime differences and the extraction on the CKM matrix element $|V_{cb}|$ more reliable.

description: We present a new catalogue of radio sources in the face-on spiral galaxy M83. Radio observations taken in 2011, 2015, and 2017 with the Australia Telescope Compact Array (ATCA) at 5.5 and 9 GHz have detected 270 radio sources. Although a small number of these sources are background extragalactic sources, most are either H II regions or supernova remnants (SNRs) within M83 itself. Three of the six historical supernovae are detected, as is the very young remnant that had been identified in a recent study, which is likely the result of a supernova that exploded in the last ~100 years but was missed. All of these objects are generally fading with time. Confusion limits our ability to measure the radio emission from a number of the SNRs in M83, but 64 were detected in unconfused regions, and these have the approximate power-law luminosity function which has been observed in other galaxies. The SNRs in M83 are systematically smaller in diameter and brighter than those that have been detected at radio wavelengths in M33. A number of the radio sources are coincident with X-ray sources in M83; most of these coincident sources turn out to be supernova remnants. Our dual frequency observations are among the most sensitive to date for a spiral galaxy outside the Local Group; despite this we were not able to place realistic constraints on the spectral indices, and as a result, it was not possible to search for supernova remnants based on their radio properties alone.

description: Abstract The Pressure Irrigation Networks is one of the major requirements in urban and regional economic development. For any agency dealing with the design of the water distribution network, an economic design will be an objective. In this research, Developed Central Force Optimization (DCFO) was used to optimize Ismail Abad water Distribution network. This network that is pressurized network and includes 19 pipes and nodes 18. Optimization of the network has been evaluated by developing an optimization model based on DCFO algorithm in MATLAB and the dynamic connection with EPANET software for network hydraulic calculation. Conclusions show DCFO runtime is less than mixed integer linear programming (MILP) method that provides absolute optimum. While optimization of DCFO (737,924 $) is 1.61% more than the absolute optimum that determined by the MILP method. The Frep parameter started at a value of 0.5 and was incremented by 0.005 whenever the absolute value of the difference between 5th array element and the average value of elements 3, 4, and 5 differed by less than 0.0005 (fitness tolerance). This method has been used to place 42 probes (Np = 42) in decision space and their initial acceleration vectors have been set to zero.

description: Abstract Shifting to agricultural practices with Climate –smart Agriculture (CSA) potential is crucial in mitigating greenhouse gas emissions. This study applied choice experiment data collected from 548 farm households across two geopolitical zones in Nigeria to assess the preferences for shifting to CSA among smallholders’ farmers using Best Worst Scaling (BWS) technique. Data analysis within ranked –ordered logit regression framework revealed that stronger preference was given to GAPs with manure followed by GAPs without manure and agroforestry across the three models. However, the farmers show strong preference for status quo as against agroforestry in the less restrictive model. Also, farming households’ attribute stronger preference to cultivating agroforestry on freehold and communal lands followed by strong preference for cultivating agroforestry and GAPs with manure on lease and communal land respectively. This shows that tenure type was only important for a shift to agroforestry and GAPs with manure. Willingness to accept (WTA) results suggested that farming households were willing to accept $237/ha & $137/ha to embrace GAPs with and without manure respectively while they were willing to pay $204/ha to avoid shifting to agroforestry in the study area.

Theory of output coupling for trapped fermionic atoms

description: We develop a dynamic theory of output coupling, for fermionic atoms initially confined in a magnetic trap. We consider an exactly soluble one-dimensional model, with a spatially localized delta-type coupling between the atoms in the trap and a continuum of free-particle external modes. Two important special cases are considered for the confinement potential: the infinite box and the harmonic oscillator. We establish that in both cases a bound state of the coupled system appears for any value of the coupling constant, implying that the trap population does not vanish in the infinite-time limit. For weak coupling, the energy spectrum of the outgoing beam exhibits peaks corresponding to the initially occupied energy levels in the trap; the height of these peaks increases with the energy. As the coupling gets stronger, the energy spectrum is displaced towards dressed energies of the fermions in the trap. The corresponding dressed states result from the coupling between the unperturbed fermionic states in the trap, mediated by the coupling between these states and the continuum. In the strong-coupling limit, there is a reinforcement of the lowest-energy dressed mode, which contributes to the energy spectrum of the outgoing beam more strongly than the other modes. This effect is especially pronounced for the one-dimensional box, which indicates that the efficiency of the mode-reinforcement mechanism depends on the steepness of the confinement potential. In this case, a quasi-monochromatic anti-bunched atomic beam is obtained. Results for a bosonic sample are also shown for comparison.

title: The Nature of the Professions. A Sociological Analysis of Professional Power, Socialisation and Ideologies.
Creators: name: Joseph, Martin
Publisher: name: The Open University
Year: 1977

description: This dissertation analyses professional power (both in society and within professional institutions), the nature of professional socialisation, and professional ideologies. Although professions appear to have little real direct political power, they exert effective pressure on governments in areas of corporate concern and will act as pressure groups to maintain their quasi monopoly position and protect the status of their expertise. Professionals also exert influence over their clients, beyond that required for effective fulfilment of their services. Despite increasing bureaucratisation, professions are largely able to maintain their power through the deference granted to their expertise, and influence over the socialisation of their members. Control over membership is the prerequisite for mobilising power. Professions control their members firstly by vetting their status, which nowadays is largely achieved by means of entrance qualifications and practical experience. Control over professionals is achieved partly by elite domination of positions in professional associations, and partly by peer group control. Conformity to professional values and practice is thereby obtained.

description: We consider quantum models corresponding to superymmetrizations of the two-dimensional harmonic oscillator based on worldline $d=1$ realizations of the supergroup SU$(\,{\cal N}/2\,|1)$, where the number of supersymmetries ${\cal N}$ is arbitrary even number. Constructed models possess the hidden supersymmetry SU$(\,{\cal N}/2\,|2)$. Degeneracies of energy levels are spanned by representations of the hidden supersymmetry group.

description: This paper evaluates the potential impact of the recently enacted forest protection laws on the number of forest fires in Argentina. The forest protection laws (at a federal and provincial level) restricts the use of forestry land in several ways, and limit the expansion of the agricultural frontier. This restriction can make forest arson potentially profitable to clear land and to expand the agricultural frontier circumventing the laws. We present a conceptual model based in the economic theory of crime to analyze forest arson decisions, and to predict individual behavior. Using panel data from 2002 to 2014 at a provincial level we present empirical evidence of systematic effects in the occurrence of forest fire as a function of the new regulation and its sequential implementation. Fixed effects and difference-in-differences estimates show that the number of fires increased transitory some 100% -200% in the main crop producer provinces during the law implementation process (2009-2011).
