description: Au Mali, la croissance agricole repose principalement sur des stratégies d’extensification. En effet, les rendements agricoles demeurent faibles tout comme l’utilisation d’intrants modernes. L’application moyenne d’engrais azoté et phosphaté par hectare de terres arables est d’environ 14 kg au Mali, ce qui est très faible comparativement à la moyenne de 40 kg/ha en Afrique de l’Est et du Sud (Theriault et al. 2015). Reconnaissant l’importance de l’intensification agricole pour l’avenir du pays, le gouvernement malien en a fait une de ses priorités, en mettant notamment en place un programme de subvention des engrais. Les cultures concernées par cette politique de subvention sont : le riz, le coton, le maïs, le blé, le mil et le sorgho.

description: The equation of state of the osmotic pressure for linear-polymer solutions in good solvents is universally described by a scaling function. We experimentally measure the osmotic pressure of the gelation process via osmotic deswelling. We find that the same scaling function for linear-polymer solutions also describes the osmotic pressure throughout the gelation process involving both the sol and gel states. Furthermore, we reveal that the osmotic pressure of polymer gels is universally governed by the semidilute scaling law of linear-polymer solutions.

Superposition of blackbodies and the dipole anisotropy: A possibility to calibrate CMB experiments

description: The CMB angular temperature fluctuations observed by COBE and WMAP enable us to place a lower limit on the spectral distortions of the CMB at any angular scale. These distortions are connected with the simple fact, that the superposition of blackbodies with different temperatures in general is not a blackbody. We show, that in the limit of small temperature fluctuations, the superposition of blackbodies leads to a y-type spectral distortion. It is known, that the CMB dipole induces a y-type spectral distortion with quadrupole and monopole angular distribution leading to a corresponding whole sky y-parameter of y~2.6\cdot 10^{-7}.We show here that taking the difference of the CMB signal in the direction of the maximum and minimum of the CMB dipole due to the superposition of two blackbodies leads to a spectral distortion with y~3.1\cdot 10^{-6}. The amplitude of this distortion can be calculated to the same precision as the CMB dipole, i.e. 0.3% today. Therefore it may be used as a source with brightness of several or tens of \muK to cross calibrate and calibrate different frequency channels of CMB surveys with precision of a few tens or hundreds of nK. Furthermore, we show in this work that primordial anisotropies for multipoles 2\leq l \leq 1000 also lead to spectral distortions but with much smaller y-parameter, i.e. y\sim 10^{-11}-10^{-9}.

description: Gravitational accretion accumulates the original mass, and this process is crucial for us to understand the initial phases of star formation. Using the specific infall profiles in optically thick and thin lines, we searched the clumps with infall motion from the Milky Way Imaging Scroll Painting (MWISP) CO data in previous work. In this study, we selected 133 sources of them as a sub-sample for further research and identification. The excitation temperatures of these sources are between 7.0 and 38.5 K, while the H_2 column densities are between 10^21 and 10^23 cm^-2. We have observed optically thick lines HCO+ (1-0) and HCN (1-0) using the DLH 13.7-m telescope, and found 56 sources of them with blue profile and no red profile in these two lines, which are likely to have infall motions, with the detection rate of 42\%. It suggests that using CO data to restrict sample can effectively improve the infall detection rate. Among these confirmed infall sources, there are 43 associated with Class 0/I young stellar objects (YSOs), and 13 are not. These 13 sources are probably associated with the sources in earlier evolutionary stage. By comparison, the confirmed sources which are associated with Class 0/I YSOs have higher excitation temperatures and column densities, while the other sources are colder and have lower column densities. Most infall velocities of the sources we confirmed are between 10^-1 to 10^0 km s^-1, which is consistent with previous studies.

description: We introduce novel high order well-balanced finite volume methods for the full compressible Euler system with gravity source term. They require no a priori knowledge of the hydrostatic solution which is to be well-balanced and are not restricted to certain classes of hydrostatic solutions. In one spatial dimension we construct a method that exactly balances a high order discretization of any hydrostatic state. The method is extended to two spatial dimensions using a local high order approximation of a hydrostatic state in each cell. The proposed simple, flexible, and robust methods are not restricted to a specific equation of state. Numerical tests verify that the proposed method improves the capability to accurately resolve small perturbations on hydrostatic states.
description: In this version we added a discussion of well-balanced boundary conditions (Section 2.3.3) and a new test case (Section 3.5)

description: Recovering the 3D structure of the surrounding environment is an essential task in any vision-controlled Structure-from-Motion (SfM) scheme. This paper focuses on the theoretical properties of the SfM, known as the incremental active depth estimation. The term incremental stands for estimating the 3D structure of the scene over a chronological sequence of image frames. Active means that the camera actuation is such that it improves estimation performance. Starting from a known depth estimation filter, this paper presents the stability analysis of the filter in terms of the control inputs of the camera. By analyzing the convergence of the estimator using the Lyapunov theory, we relax the constraints on the projection of the 3D point in the image plane when compared to previous results. Nonetheless, our method is capable of dealing with the cameras' limited field-of-view constraints. The main results are validated through experiments with simulated data.

description: The energy and momentum lost by a hard parton propagating through hot and dense matter has to be redistributed during the nuclear medium evolution. Apart from heating the medium, there is the possibility that collective modes are excited leading to the emergence of Mach cones or Cherenkov radiation. Recent two-particle correlation measurements by STAR \cite{Wang:2004kf} and PHENIX \cite{Adler:2005ee} at RHIC indicate that such phenomena may play an important role in understanding the jet-medium interactions. Possible collective modes are discussed and it is demonstrated that Mach cones as created by colorless or colored sound are a possible explanation of the hardronic two-particle correlation data.

description: Raising agricultural productivity remains a major challenge in developing countries. Farm productivity is especially low in Sub-Saharan Africa, where fertilizer use lags far behind the rest of the world. Identifying effective strategies for raising fertilizer use in Africa has been a longstanding policy priority. While most of the region has struggled to raise fertilizer use in a sustainable manner, several countries have recorded impressive steady growth in fertilizer use, suggesting that there may be important success stories from which to learn.

Numerical examples that validate the theoretical results, are presented separately.

description: Climate smart agriculture (CSA) has emerged as an approach to enhance the resilience of farming systems to the effects of climate change. CSA is defined by three principle objectives: 1) sustainably increasing agricultural productivity and incomes; 2) adapting and building resilience to climate change; and 3) reducing and/or removing greenhouse gases emissions, where possible. In Africa there is particular interest in identifying strategies to encourage farmers to adopt practices and technologies that enable their farms to be more resilient and productive, while at the same time identifying system-wide collective action to promote a wide range of ex ante risk management activities and ex post coping strategies.

description: Glaucoma is the second most common cause of visual impairment in the UK, with visual impairment registrations having increased by 22% since 2010. Glaucoma refers to a group of optic neuropathies leading to visual impairment and blindness4. If glaucoma remains untreated, it may produce optic nerve damage, leading to vision loss. Consequently, visual field tests can be extremely valuable for glaucoma. At the same time, visual field assessment should be performed at baseline and periodically in the glaucoma follow-up or monitor the effectiveness of adopted therapeutic schemes. Any visual field test can be masked by one or more artefacts, which can either lead to the incorrect result of visual field loss or to the possible deterioration of existing loss. One of the most important factors is the perimetric learning effect that is present in almost all types of perimetry. To minimize the learning effect, we either have to conduct a practice test procedure, as a demonstration for the patient without collecting data, or to calculate and establish a learning index of the specific patient. By the establishment of such an index, assist the clinician in detecting possible masked or overestimated visual field defects or progression of glaucoma damage.

description: The $U(1)_X$ extension of the minimal supersymmetric standard model(MSSM) is called as $U(1)_X$SSM with the local gauge group $SU(3)_C\times SU(2)_L \times U(1)_Y \times U(1)_X$. $U(1)_X$SSM has three singlet Higgs superfields beyond MSSM. In $U(1)_X$SSM, the mass matrix of neutralino is $8\times8$, whose lightest mass eigenstate possesses cold dark matter characteristic. Supposing the lightest neutralino as dark matter candidate, we study the relic density. For dark matter scattering off nucleus, the cross sections including spin-independent and spin-dependent are both researched. In our numerical results, some parameter space can satisfy the constraints from the relic density and the experiments of dark matter direct detection.

description: In this paper an approach for broadening of operational band in a dense array of dipole antennas by implementing passive split-loop resonators (SLRs) as decouplers is presented. Compared to the previous method, where three closely located active dipoles were decoupled by two passive dipole, the operational band is significantly improved from $0.5 \%$ to $1.6 \%$ at the same level of decoupling -8dB for the cross-talk and inter-channel transmittance. To delineate, the presence of two SLRs results in birefringence of the resonant interaction of SLRs which creates two different eigenmodes for decoupling. As a result, a dual-resonant decoupled band is obtained. Alongside with analytical investigation, numerical and experimental investigations verify the veracity of our approach. Moreover, the possibility of decoupling by SLRs for arrays with more active dipoles is investigated numerically.
Simon and picture-word Stroop tasks of inhibition in monolingual and bilingual grade 2 children
Creators: name: Campbell, Kristina J.
Publisher: name: University of British Columbia
Year: 2011

description: This study investigated the effect of bilingualism on children's performance on two tasks of inhibition. English monolinguals (n =21) and successive Chinese-English bilinguals (n =21) in Grade 2 (ages 7-8) completed the Simon task and a picture-word Stroop task. Both tasks required the inhibition of perceptual attributes of the stimuli; certain conditions of the picture-word Stroop task also required inhibition of conceptual information. In the Simon task, children were required to ignore salient spatial cues and respond only to stimulus colour. As expected, both the monolingual and bilingual groups in this study showed faster RTs on the condition that did not involve a spatial conflict than the one that involved a spatial conflict. In contrast with previous research findings, however, a bilingual group advantage was not observed on this task. In the picture-word Stroop task, children had to name pictures with or without incongruent words written inside. The distracters in different conditions were hypothesized to access the semantic/conceptual level to varying degrees, in accordance with a connectionist model of language processing. Across all participants, real-word distracters were associated with lower accuracy and slower RTs than all other distracters. In general, RT interference varied with the nature of the distracter: words that accessed the semantic level more directly were associated with greater interference, and words that did not access the semantic level produced less interference. No monolingual-bilingual group differences were observed on this task. This study illustrates the feasibility of applying connectionist processing models to language tasks of inhibition. Implications of these results for current explanations of the bilingual inhibitory advantage are discussed.

description: In this work, a first cryogenic characterization of a scintillating LiAlO$_{2}$ single crystal is presented. The results achieved show that this material holds great potential as a target for direct dark matter search experiments. Three different detector modules obtained from one crystal grown at the Leibniz-Institut für Kristallzüchtung (IKZ) have been tested to study different properties at cryogenic temperatures. Firstly, two 2.8 g twin crystals were used to build different detector modules which were operated in an above-ground laboratory at the Max Planck Institute for Physics (MPP) in Munich, Germany. The first detector module was used to study the scintillation properties of LiAlO$_{2}$ at cryogenic temperatures. The second achieved an energy threshold of (213.02$\pm$1.48) eV which allows setting a competitive limit on the spin-dependent dark matter particle-proton scattering cross section for dark matter particle masses between 350 MeV/c$^{2}$ and 1.50 GeV/c$^{2}$. Secondly, a detector module with a 373 g LiAlO$_{2}$ crystal as the main absorber was tested in an underground facility at the Laboratori Nazionali del Gran Sasso (LNGS): from this measurement it was possible to determine the radiopurity of the crystal and study the feasibility of using this material as a neutron flux monitor for low-background experiments.

description: We present theoretical models of black hole (BH) populations in young stellar environments, such as starbursts and young star clusters. Using a population synthesis approach we compute the formation rates and characteristic properties of single and binary BHs for various representative ages and choices of parameters. We find that most of the BHs (typically 80% for an initial 50% binary fraction) are single, but with many originating from primordial binaries (which either merged into a single massive star or were disrupted following a supernova explosion). A smaller but significant fraction (typically 20%) of the BHs remain in binary systems. Main-sequence stars are the most frequent BH companions, but massive BH--BH binaries are the next most numerous group. The most massive BHs found in our simulations reach 80 Msun, and are formed through mergers of massive binary components. If formed in a dense star cluster such a massive stellar BH may become the seed for growth to a more massive (``intermediate-mass'') BH. Although we do not include dynamical interactions, our results provide realistic initial conditions for N-body simulations of dense star clusters (e.g., globular clusters) including primordial BHs.

description: The superconducting properties of carbon nanotube ropes are studied using a new computational framework that incorporates the renormalization of intratube interactions and the effect of intertube Coulomb screening. This method allows to study both the limits of thin and thick ropes ranging from purely one-dimensional physics to the setting of three-dimensional Cooper-pair coherence, providing good estimates of the critical temperature as a function of the rope physical parameters. We discuss the connection of our results with recent experiments.

description: We numerically study the possibility of many-body localization transition in a disordered quantum dimer model on the honeycomb lattice. By using the peculiar constraints of this model and state-of-the-art exact diagonalization and time evolution methods, we probe both eigenstates and dynamical properties and conclude on the existence of a localization transition, on the available time and length scales (system sizes of up to N=108 sites). We critically discuss these results and their implications.

description: An n-particle 3-dimensional Wigner quantum oscillator model is constructed explicitly. It is non-canonical in that the usual coordinate and linear momentum commutation relations are abandoned in favour of Wigner's suggestion that Hamilton's equations and the Heisenberg equations are identical as operator equations. The construction is based on the use of Fock states corresponding to a family of irreducible representations of the Lie superalgebra sl(1|3n) indexed by an A-superstatistics parameter p. These representations are typical for p\geq 3n but atypical for p<3n. The branching rules for the restriction from sl(1|3n) to gl(1) \oplus so(3) \oplus sl(n) are used to enumerate energy and angular momentum eigenstates. These are constructed explicitly and tabulated for n\leq 2. It is shown that measurements of the coordinates of the individual particles gives rise to a set of discrete values defining nests in the 3-dimensional configuration space. The fact that the underlying geometry is non-commutative is shown to have a significant impact on measurements of particle separation. In the atypical case, exclusion phenomena are identified that are entirely due to the effect of A-superstatistics. The energy spectrum and associated degeneracies are calculated for an infinite-dimensional realisation of the Wigner quantum oscillator model obtained by summing over all p. The results are compared with those applying to the analogous canonical quantum oscillator.

description: Public support for agriculture in the European Union (EU) and other European countries targets two main objectives: providing public goods and securing a fair standard of living for farmers. However, whether the current level of spending on measures targeting these two goals reflects taxpayer preferences is unknown. We used a cross-section of countries to explore how levels of support relate to likely indicators of taxpayer demand. The indicators were derived from theoretical considerations, empirical literature on the demand for public goods, and opinion research about specific policy preferences. We evaluated eleven expectations concerning the relationships between these indicators and spending on direct payments (pillar 1), total payments for voluntary measures (pillar 2) and agri-environment measures in the reference year 2012. We found that spending on public goods was consistently related to variations in income and other indicators of willingness to pay. Spending on income support, in contrast, did not show the expected relations with preference indicators. Furthermore, the study revealed that reliable information about parameters of taxpayer preferences for agricultural support is currently largely lacking. More decentralized and participatory processes in agricultural policymaking would improve our knowledge about taxpayer preferences, and reduce the information needs of policy makers.

description: This article presents an analysis of risk management by French cereal farmers Producers are subject to market and production risks and to environmental restrictions. The paper analyses cereal farmers’ strategies to manage risks through marketing contracts and production decisions. Three main categories of marketing contracts are adopted bearing different risk levels: forward contracts, average price contracts and spot contracts. A hundred wheat producers are surveyed in SouthWest France. The quantitative analysis of their contractual choices shows that risk perceptions and the farmer’s level of education have an influence on contractual choice while crop diversification is negatively correlated with forward contracts.
Portentous fantasies : Pliny's representation of the Magi in the Historia Naturalis
Creators: name: Dykstra, Sarah Sophia
Publisher: name: University of British Columbia
Year: 2011

description: This study examines Pliny the Elder's representation of the Magi in the Historia Naturalis. It seeks to determine not only who the Magi were in Pliny's estimation but also how they were construed in the Roman popular imagination. The pronounced antagonism that Pliny demonstrates toward these occult practitioners is rooted in the fact that the whole notion of magic, as it was understood in the ancient world, was embedded in a negative labelling-system, and that the identity of the magician existed primarily in the imagination of those who were doing the labelling (i.e., branding others as "magicians"). In the HN, Pliny's Magi are therefore represented as the proverbial "other" - outsiders who are perceived as engaging in foreign (and thus loathsome and abhorrent) practices. Pliny's representation of and attitude toward the Magi therefore exemplify how magic-workers have commonly been regarded as individuals who engage in ritual or religious activity that is not endorsed by the dominant social institutions of the cultures in which they operate.

description: The agricultural sector in Europe is heavily dependent on support payments made as part of the Common Agricultural Policy (CAP). In 2013, a political agreement on a CAP reform was reached that led to the introduction of a Basic Payment Scheme (BPS). The agreement allowed for a wide range of implementations across EU member states with BPS implementation options ranging from models with flat rate per hectare payments determined at regional or national level, to models where existing historically determined payment rates per hectare transition towards, but not to, a flat rate per hectare. This paper explores the role that such payments and changes in their distribution could play in reducing farm income inequality in the UK and Ireland. Flat rate per farm payments are also considered here to explore how a more dramatic reform would reduce inequality. Movement towards flat rate per hectare payments does not uniformly decrease inequality of Farm Net Value Added (FNVA) in contrast to what one may anticipate a priori, in fact in Wales, Scotland and Northern Ireland the inequality of FNVA increases in this analysis. In contrast, flat rate per farm payments reduce inequality substantially.

description: This paper investigated farmers’ self-stated adoption motives and the perceived effectiveness of agri-environmental measures in Finland. The measures were classified into ten distinct categories according to their prescriptions. The adoption motives were related to contextual factors, production factors and perceived effectiveness of the measures, while effectiveness was further related to land use, input use and the final impacts. The results indicate that the adoption motivations and the perceived effectiveness of the measures are related to their prescriptions: measures targeting the same problem with different prescriptions fit the aims and farming strategies of different farmers.
