description: Abstract The System of Rice Intensification (SRI) is recognized as a promising systemic approach to enhance rice production at affordable costs without harming the environment. Yet there is no consensus in the literature with respect to the factors influencing the adoption as well as the welfare outcomes of adoption. This paper identifies the factors that affect farmers’ decisions to adopt SRI in major rice producing States of India and its impact on rice yield and household income. The multinomial endogenous treatment effects model adopted in the present study analyses the factors influencing the adoption and the impact of adoption in a joint framework. Results suggest that household assets, irrigation, access to information etc. increased the likelihood of household adopting SRI whereas the size of landholding, the number of years household stayed in rice cultivation, fear of poor yield, etc. decreased the likelihood of adopting SRI. The welfare impacts of SRI adoption revealed that all combinations of SRI individually and as a group (plant management, water management and soil management) had an impact on yield. However, the impact of SRI adoption on household income was quite mixed.

description: In this paper we report results of collisional N-body simulations of the dynamical evolution of equal-mass star clusters containing a massive central black hole. Each cluster is composed of between 5,000 to 180,000 stars together with a central black hole which contains between 0.2% to 10% of the total cluster mass. We find that for large enough black hole masses, the central density follows a power-law distribution with slope ρ\sim r^{-1.75} inside the radius of influence of the black hole, in agreement with predictions from earlier Fokker Planck and Monte Carlo models. The tidal disruption rate of stars is within a factor of two of that derived in previous studies. It seems impossible to grow an intermediate-mass black hole (IMBH) from a M \le 100 Msun progenitor in a globular cluster by the tidal disruption of stars, although M = 10^3 Msun IMBHs can double their mass within a Hubble time in dense globular clusters. The same is true for the supermassive black hole at the centre of the Milky Way. Black holes in star clusters will feed mainly on stars tightly bound to them and the re-population of these stars causes the clusters to expand, reversing core-collapse without the need for dynamically active binaries. Close encounters of stars in the central cusp also lead to an increased mass loss rate in the form of high-velocity stars escaping from the cluster. A companion paper will extend these results to the multi-mass case.

description: The main goal of this paper is to evaluate how irrigated areas with flooding, furrows, sprinkler, centralpivot, drip and other methods of irrigation as well as the source of water used to irrigation influence the technical efficiency. Furthermore, we evaluate the behavior of the technical efficiency by farm size. The TE scores are obtained through the Stochastic Frontier Approach (SFA), which simultaneously models the production technical inefficiency. The results showed that, initially, there is a positive and linear relationship between efficiency and farm size, however, when the farms reaches 100 hectares the relationship becomes inverse, characterizing U-inverted shape. In general, the irrigated areas with different methods of irrigation and the source of the water have a positive influence on the technical efficiency of farmers. Other factors such as cooperatives membership, education, experience and rural credit also have a positive influence on efficiency. Finally, we conclude that large farmers are less efficient than small-scale farmers.

description: The recent literature on economic development in Africa emphasizes that the agricultural transformation still needs to play a key role for poverty reduction and food security. As compared to the situation of the Green Revolution in Asia, there are new opportunities for the agricultural transformation in Africa, but also new challenges. Against this background, the paper shows that is essential that countries develop sufficient political will to achieve an agricultural transformation. The paper presents a concept of political will and applies this concept empirically, using a range of indicators of political will, such as government expenditure on agriculture. The paper proposes various demand-side and supply-side strategies to strengthen the political will to promote the agricultural transformation in Africa.

description: We analyse the existence of closed timelike curves in spacetimes which possess an isometry. In particular we check which discrete quotients of such spaces lead to closed timelike curves. As a by-product of our analysis, we prove that the notion of existence or non-existence of closed timelike curves is a T-duality invariant notion, whenever the direction along which we apply such transformations is everywhere spacelike. Our formalism is straightforwardly applied to supersymmetric theories. We provide some new examples in the context of D-branes and generalized pp-waves.

description: This paper addresses a set of methodological questions. First, it assesses the variation of the level of ANA in different non-hypothetical CA formats. Second, it explores whether asking respondents to report the attributes they ignored after each choice set or at the end of the choice task yield comparable results. Lastly, it explores the implications of taking into account ANA information on respondents’ willingness to pay and on the external predictive powers of the estimated parameters. To answer these research questions, three treatments were carried out, non-hypothetical CE (NHCE), non-hypothetical RCA (NHRCA) and nonhypothetical BWS (NHBWS). The results reveal that taking into account ANA information significantly improved the goodness-of-fit of the estimated models, especially when full ranking information is considered as NHRCA and NHBWS. In term of marginal WTP estimates, the results show neither of the two ANA approaches appears to be a clear winner. Also, our results show that taken into account ANA information not seem to improve significantly the predictive power of estimated parameters.

description: The consumption of highly processed food has been singled out as one of the factors responsible for the rapidly increasing obesity prevalence and its associated non-communicable diseases and costs. While obesity prevalence is still comparatively low in the lower income Sub-Saharan Africa (SSA), its development prospects render its markets especially interesting for these foods whose consumption is already growing at higher rates than in developed countries. This might be reflected in the massive rise in obesity prevalence growth rates in SSA over the past decade. Nevertheless, many of these countries are simultaneously struggling with high undernutrition prevalence. With a focus on SSA, this study econometrically investigates the effect of higher import tariffs on highly processed vis-a-vis less processed foods with respect to their impacts on obesity and underweight prevalence utilizing a newly constructed cross-country panel dataset. The effects of the tariff differences found are significant and substantial in cases differentiated by income level of the country as well as gender. The results more generally show that policies affecting the consumer price differential between the two food groups are effective for influencing obesity and underweight prevalence and that these two issues cannot be treated as being separate.

description: For the first time, complete source distributions for the emission and absorption of acoustic and electromagnetic wavelets are defined and computed, both in spacetime and Fourier space. The biggest surprise is the great simplicity of the Fourier sources as compared to the rather convoluted spacetime expressions obtained from the original wavelets. This suggests that the associated pulsed-beam propagators may play a fundamental role in emission and absorption processes including focus or "directivity." It also opens the way to constructing FFT-based algorithms for pulsed-beam analyses of acoustic and electromagnetic waves.

description: The core objective of this paper is to examine the relationship between the prices of agricultural commodities with the oil price, gas price, coal price and exchange rate (USD/Rand). In addition, the paper tries to fit an appropriate model that best describes the log return price volatility and estimate Value-at- Risk (VaR). The data used in this study are the daily returns of agricultural commodity prices from 02 January 2007 to 31st October 2016. The paper applies the three-state Markov-switching (MS) regression, the standard single-regime GARCH, and the Markov-switching GARCH (MS-GARCH) models. To choose the best fit model, the log-likelihood function, Akaike information criterion (AIC), Bayesian information criterion (BIC) and deviance information criterion (DIC) are employed under different distributions for innovations. The results indicate that the price of agricultural commodities was found to be significantly associated with the price of coal, the price of natural gas, price of oil and exchange rate. Moreover, for most of the agricultural commodities considered in this paper, the MS-GARCH models under the MCMC approach outperformed the standard single regime GARCH models in measuring VaR. In conclusion, this paper provided a practical guide for modelling agricultural commodity prices by MS regression and MSGARCH processes.

description: For the description of nonsequential double ionization (NSDI) of rare-gas atoms by a strong linearly polarized laser field, the quantum-mechanical $S$-matrix diagram that incorporates rescattering impact ionization is evaluated in the strong-field approximation. We employ a uniform approximation, which is a generalization of the standard saddle-point approximation. We systematically analyze the manifestations of the electron-electron interaction in the momentum distributions of the ejected electrons: for the interaction, by which the returning electron frees the bound electron, we adopt either a (three-body) contact interaction or a Coulomb interaction, and we do or do not incorporate the mutual Coulomb repulsion of the two electrons in their final state. In particular, we investigate the correlation of the momentum components parallel to the laser-field polarization, with the transverse momentum components either restricted to certain finite ranges or entirely summed over. In the latter case, agreement with experimental data is best for the contact interaction and without final-state repulsion. In the former, if the transverse momenta are restricted to small values, comparison of theory with the data shows evidence of Coulomb effects. We propose that experimental data selecting events with small transverse momenta of \textit{both} electrons are particularly promising in the elucidation of the dynamics of NSDI. Also, a classical approximation of the quantum-mechanical $S$ matrix is formulated and shown to work very well inside the classically allowed region.

description: We introduce a learning framework for automated floorplan generation which combines generative modeling using deep neural networks and user-in-the-loop designs to enable human users to provide sparse design constraints. Such constraints are represented by a layout graph. The core component of our learning framework is a deep neural network, Graph2Plan, which converts a layout graph, along with a building boundary, into a floorplan that fulfills both the layout and boundary constraints. Given an input building boundary, we allow a user to specify room counts and other layout constraints, which are used to retrieve a set of floorplans, with their associated layout graphs, from a database. For each retrieved layout graph, along with the input boundary, Graph2Plan first generates a corresponding raster floorplan image, and then a refined set of boxes representing the rooms. Graph2Plan is trained on RPLAN, a large-scale dataset consisting of 80K annotated floorplans. The network is mainly based on convolutional processing over both the layout graph, via a graph neural network (GNN), and the input building boundary, as well as the raster floorplan images, via conventional image convolution.

description: We have studied the anisotropy of the London penetration depth, which was obtained from reversible magnetization measurements with the magnetic field both parallel and perpendicular to the c-axis. The anisotropy of the London penetration depth has a smaller magnitude than the anisotropy of the upper critical field and increases with temperature while that of the upper critical field decreases as reported earlier. This behavior is in sharp contrast with the behaviors of superconductors with one superconducting energy gap. The temperature dependence of the anisotropies of the London penetration depth and of the upper critical field can be well explained within the theory of two-gap superconductivity in MgB2.

description: In this paper, we analyze the total work extracted and the efficiency of the magnetic Otto cycle in its classic and quantum versions. As a general result, we found that the work and efficiency of the classical engine is always greater than or equal to that of its quantum counterpart independent of the working substance. In the classical case, this is due to the fact that the working substance is always in thermodynamic equilibrium at each point of the cycle, maximizing the energy extracted in the adiabatic paths. We apply this analysis to the case of a two-level system, finding that the work and efficiency in Otto's quantum and classical cycle are identical, regardless of the working substance, and we obtain similar results for a multilevel system where a linear relationship between the spectrum of energies of the working substance and the external magnetic field is fulfilled. Finally, we show an example of a three-level system in which we compare two zones in the entropy, temperature and magnetic field diagram to find which is the most efficient when performing a thermodynamic cycle. This work provides a practical way to look for temperature and magnetic field zones in the entropy diagram that can maximize the power extracted from Otto's magnetic engine.

description: Exotic quantum phenomena have been demonstrated in recently discovered intrinsic magnetic topological insulator MnBi2Te4. At its two-dimensional limit, quantum anomalous Hall (QAH) effect and axion insulator state are observed in odd and even layers of MnBi2Te4, respectively. The measured band structures exhibit intriguing and complex properties. Here we employ low-temperature scanning tunneling microscopy to study its surface states and magnetic response. The quasiparticle interference patterns indicate that the electronic structures on the topmost layer of MnBi2Te4 is different from that of the expected out-of-plane A-type antiferromagnetic phase. The topological surface states may be embedded in deeper layers beneath the topmost surface. Such novel electronic structure presumably related to the modification of crystalline structure during sample cleaving and re-orientation of magnetic moment of Mn atoms near the surface. Mn dopants substituted at the Bi site on the second atomic layer are observed. The ratio of Mn/Bi substitutions is 5%. The electronic structures are fluctuating at atomic scale on the surface, which can affect the magnetism of MnBi2Te4. Our findings shed new lights on the magnetic property of MnBi2Te4 and thus the design of magnetic topological insulators.

description: Brain-computer interfaces (BCIs) and their associated technologies have the potential to shape future forms of communication, control, and security. Specifically, the steady-state visual evoked potential (SSVEP) based BCIs have the advantages of better recognition accuracy, and higher information transfer rate (ITR) compared to other BCI modalities. To fully exploit the capabilities of such devices, it is necessary to understand the underlying biological features of SSVEPs and design the system considering their inherent characteristics. This paper introduces bio-inspired filter banks (BIFBs) for improved SSVEP frequency recognition. SSVEPs are frequency selective, subject-specific, and their power gets weaker as the frequency of the visual stimuli increases. Therefore, the gain and bandwidth of the filters are designed and tuned based on these characteristics while also incorporating harmonic SSVEP responses. The BIFBs are utilized in the feature extraction stage to increase the separability of classes. This method not only improves the recognition accuracy but also increases the total number of available commands in a BCI system by allowing the use of stimuli frequencies that elicit weak SSVEP responses. The BIFBs are promising particularly in the high-frequency band, which causes less visual fatigue. Hence, the proposed approach might enhance user comfort as well. The BIFB method is tested on two online benchmark datasets and outperforms the compared methods. The results show the potential of bio-inspired design, and the findings will be extended by including further SSVEP characteristics for future SSVEP based BCIs.

We estimate the imaginary part of the charming penguin by an effective field theory inspired by the Heavy Quark Effective Theory and parameterize its real part. The final results for branching ratios depend on only two real parameters and show a significant role of the charming penguins. The overall agreement with the available experimental data is satisfactory.

A simple generalization of Prandtl-Tomlinson model to study nanoscale rolling friction

description: Prandtl-Tomlinson (PT) model has been very successful in explaining nanoscale friction in a variety of situations. However, the simplistic PT model, on account of having a point mass being dragged across a sinusoidal force field, cannot be used for studying rolling friction at nanoscales. In this manuscript, we generalize the PT model as a collection of point particles arranged in a circle of radius $R$. The resulting ``rigid body'' is driven in a composite force field by a moving spring (of stiffness $k$) connected to the center of mass of the rigid body in presence of damping. The force field is a product of the familiar sinusoidal function used in the PT model with a parametrically controlled ($λ$) exponentially varying function that is dependent on the vertical coordinates of the particles. Our generalized model degenerates to the standard PT model if $R \ll 1$ and $λ\to 0$. With $R \sim 1$ and $λ\to 0$, the model undergoes a transition from sticky dynamics to smooth dynamics as $k$ is increased to a critical value. The analytical expression agrees well with the simulation results. Similar analytical expressions have been derived for $ λ\neq 0$ as well. In this scenario, the sticky dynamics is experienced in both $x$ and $y$ directions, and our numerical results agree with the analytical solution for $x$ direction. The dynamics, investigated numerically for the general case of $R \sim 1$ and $λ\neq 0$, reveals several interesting aspects of nanoscale tribology including the regimes where energy dissipation due to friction is minimum. Further the results from our proposed model are in qualitative agreement with those from MD simulations as well. We believe that the simplicity of our model along with its similarity to the PT model may make it a popular tool for analyzing complicated nanotribological regimes.

description: "Non Conforming Use" is a term used generally by local and governmental planning agencies to describe uses of land and buildings which do not accord with their planning policies. It appears to have differing quasi-legal overtones as between authorities. The object of this study is to determine the origins of land use designation and those circumstances which give rise to non conformity as interpreted by the planning authorities in England and Wales. An England/Wales survey and a control area survey were conducted and the incidence of conflict use examined from available local authority recorded enforcement decisions to establish any derived order of use conflict. The established prime conflict was then studied in a more accessible local area by reference to selected case studies. Possible causes of conflict were illustrated from both the view of County and District implemented planning policy and that of the user. The surveys reveal a widespread order and incidence of "conflict uses" throughout the country. This widespread order and incidence may arise from a common ethos of interpretation. Suddenly increased levels of served enforcement notices show a more efficient system of detection and public participation because of recent changes in the law which give the public more legal opportunity to complain against "pollution". Within these increasing levels, the order of conflict uses stays constant but an increasing number of the "offenders" are being declared innocent by the appeal process (which is in effect an internal process because the Secretary of State, Department of the Environment, is also the Minister for planning authorities and planning policies). There is a distinction between law and local planning policy, but where land uses are concerned, enforcement notices are served primarily on the basis of legal interpretation of the expression "material change in use". In other words, the law is to some extent able to be interpreted, or used, to suit the local planning authorities' view of their policy. They are also the prosecutors. Whilst the study does involve examination of quasi-legal issues, it is not intended to be a purely planning critique, although the conclusions may involve such a critique because the study has been made against the assumptions that processes in the planning system, including the element of public participation, are direct causal factors of nonconformity and its apparent increase measured as a use conflict.

description: The phase transition to a deconfined phase is studied and the consequences in the formation of neutron stars are investigated. We use the quark-meson-coupling model for the hadron matter and the MIT Bag model for the quark matter in order to build the appropriate equations of state for the hybrid stars. The properties of the stars are then calculated. The differences between unpaired and color-flavor locked quark matter are discussed.

description: The relative current density $n^i$ of conduction neutrons in a neutron star crust beyond the neutron drip threshold can be expected to be related to the corresponding particle momentum covector $p_i$ by a linear relation of the form $n^i=K^{ij}p_j$ in terms of a physically well defined mobility tensor $K^{ij}$. This result is describable as an ``entrainment'' whose effect - wherever the crust lattice is isotropic - will simply be to change the ordinary neutron mass m to an effective mass $m_\star$ such that in terms of the relevant number density n of unconfined neutrons we shall have $K^{ij}=n/m_\starγ^{ij}$. In a preceding analysis based on an independent particle treatment using Bloch boundary conditions to obtain the distribution of energy $E_k$ and associated group velocity $v_k^i=\partial E_k/\partial\hbar k_i$ as a function of wavenumber $k_i$, it was shown that the mobility tensor would be given by $K^{ij}\propto\int d^3 k v_k^i v_k^jδ\{E_k-μ\}$, where $μ$ is the Fermi energy. Using the approach due to Bogoliubov, it is shown here that the effect of BCS pairing with an energy gap Δ_F and corresponding quasiparticle energy function \EE_k=\sqrt{(E_k-μ)^2+Δ_F^2}$ will just be to replace the Dirac distributional integrand by a smoother distribution : $K^{ij}\propto \int d^3 k v_k^i v_k^j Δ_F^2 /\EE^3_k$. It is also shown how the pairing condensation gives rise to superfluidity in the technical sense of providing (meta) stability against resistive perturbations for a current that is not too strong (its momentum $p_i$ must be small enough to give $2|p_i v_k^i|

description: Over the past three decades, we have witnessed one of the great revolutions in our understanding of the cosmos - the dawn of the Exoplanet Era. Where once we knew of just one planetary system (the Solar system), we now know of thousands, with new systems being announced on a weekly basis. Of the thousands of planetary systems we have found to date, however, there is only one that we can study up-close and personal - the Solar system. In this review, we describe our current understanding of the Solar system for the exoplanetary science community - with a focus on the processes thought to have shaped the system we see today. In section one, we introduce the Solar system as a single well studied example of the many planetary systems now observed. In section two, we describe the Solar system's small body populations as we know them today - from the two hundred and five known planetary satellites to the various populations of small bodies that serve as a reminder of the system's formation and early evolution. In section three, we consider our current knowledge of the Solar system's planets, as physical bodies. In section four, we discuss the research that has been carried out into the Solar system's formation and evolution, with a focus on the information gleaned as a result of detailed studies of the system's small body populations. In section five, we discuss our current knowledge of planetary systems beyond our own - both in terms of the planets they host, and in terms of the debris that we observe orbiting their host stars. As we learn ever more about the diversity and ubiquity of other planetary systems, our Solar system will remain the key touchstone that facilitates our understanding and modelling of those newly found systems, and we finish section five with a discussion of the future surveys that will further expand that knowledge.

Electric-Field Control of the Interlayer Exchange Coupling for Magnetization Switching

description: We propose an electric-field-controlled mechanism for magnetization switching assisted solely by the interlayer-exchange coupling (IEC) between the fixed and the free magnets, which are separated by two oxide barriers sandwiching a spacer material known for exhibiting large IEC. The basic idea relies on the formation of a quantum-well (QW) within the spacer material and controlling the transmission coefficient across the structure with an electric-field via the resonant tunneling phenomena. Using non-equilibrium Green's function (NEGF) method, we show that the structure can exhibit a bias-dependent oscillatory IEC that can switch the free magnet to have either a parallel or an antiparallel configuration with respect to the fixed magnet, depending on the sign of the IEC. Such bi-directional switching can be achieved with the same voltage polarity but different magnitudes. With proper choice of the spacer material, the current in the structure can be significantly reduced. Due to the conservative nature of the exerted torque by the IEC, the switching threshold of the proposed mechanism is decoupled from the switching speed, while the conventional spin-torque devices exhibit a trade-off due to the non-conservative nature of the exerted torque.

description: Cybersecurity of industrial control system is a very complex and challenging research topic, due to the integration of these systems in national critical infrastructures. The control systems are now interconnected in industrial networks and frequently to the Internet. In this context they are becoming targets of various cyber attacks conducted by malicious people such as hackers, script kiddies, industrial spies and even foreign armies and intelligence agencies. In this paper the authors propose a way to model the most frequent attacker profiles and to estimate the success rate of an attack conducted in given conditions. The authors use a fuzzy approach for generating attacker profiles based on attacker attributes such as knowledge, technical resources and motivation. The attack success rate is obtained by using another fuzzy inference system that analyzes the attacker profile and system intrinsic characteristics.

description: We present a Monte Carlo study of the high-temperature phase of the two-dimensional driven lattice gas at infinite driving field. We define a finite-volume correlation length, verify that this definition has a good infinite-volume limit independent of the lattice geometry, and study its finite-size-scaling behavior. The results for the correlation length are in good agreement with the predictions based on the field theory proposed by Janssen, Schmittmann, Leung, and Cardy. The theoretical predictions for the susceptibility and the magnetization are also well verified. We show that the transverse Binder parameter vanishes at the critical point in all dimensions $d\ge 2$ and discuss how such result should be expected in the theory of Janssen et al. in spite of the existence of a dangerously irrelevant operator. Our results confirm the Gaussian nature of the transverse excitations.
