description: Building on recent literature on rural wealth creation, this paper explores the dynamics of household net worth accumulation for residents in metro, nonmetro, and nonmetro-nonadjacent areas and seeks the drivers of differences in rural and urban household wealth and wealth accumulation. Using data from the Panel Study of Income Dynamics (PSID), regressions of net worth -- including financial capital, home equity, net value of farm and business assets and other property -- are estimated for a sample of households between 1999 and 2009. The results show that nonmetro and nonadjacent effects on household net worth are explained partly by differences in demographic composition, wages and property values.

description: Within random matrix theory for quantum dots, both the dot's one-particle eigenlevels and the dot-lead couplings are statistically distributed. While the effect of the latter on the conductance is obvious and has been taken into account in the literature, the statistical distribution of the one-particle eigenlevels is generally replaced by a picket-fence spectrum. Here we take the random matrix theory eigenlevel distribution explicitly into account and observe significant deviations in the conductance distribution and magnetoconductance of closed quantum dots at experimentally relevant temperatures.

description: Governing the process of economic transformation is one of the most prominent issues arising since the fall of the Iron Curtain. After the successful transition model of the Central and Eastern European countries and their EU accession, the main anchors of the EU enlargement are directed into the South Eastern part of the continent. Most obviously, the EU enlargement is entering into the new phase of its expansion. In this paper we evaluate the state of transformation in the agricultural sector of the potential EU members comprising countries constituting the South Eastern Europe (the Western Balkans), and Turkey. We analyze whether the significant transitional changes occurred in the agricultural sector in observed countries. The main areas of our interest involve the comparative analysis of the state of economic transformation and the income convergence, the economic importance of agriculture in the potential EU Members, impact of economic transformation on the agricultural assets, agricultural policy implications, investigation of consumption patterns and poverty prevalence.

description: The most general geometrical scenario in which the brane-world program can be implemented is investigated. The basic requirement is that it should be consistent with the confinement of gauge interaction, the existence of quantum states and the embedding in a bulk with arbitrary dimensions, signature and topology. It is found that the embedding equations are compatible with a wide class of Lagrangians, starting with a modified Einstein-Hilbert Lagrangian as the simplest one, provided minimal boundaries are added to the bulk. A non-trivial canonical structure is derived, suggesting a canonical quantization of the brane-world geometry relative to the extra dimensions, where the quantum states are set in correspondence with high frequency gravitational waves. It is shown that in the cases of at least six dimensions, there exists a confined gauge field included in the embedding structure. The size of extra dimensions compatible with the embedding is calculated and found to be different from the one derived with product topology.

description: We present a study of singlet-doublet vector-like leptonic dark matter (DM) in the framework of two Higgs doublet model (2HDM), where the dark sector is comprised of one doublet and one singlet vectorlike fermions (VLFs). The DM, that arises as an admixture of the neutral components of the VLFs, is stabilized by an imposed discrete symmetry $\mathcal{Z}_2^{'}$ . We test the viability of the model in the light of observations from PLANCK and recent limits on spin-independent direct detection experiments, and search for its possible collider signals. In addition, we also look for the stochastic gravitational wave (GW) signatures resulting from strong first order phase transition due to the presence of the second Higgs doublet. The model thus offers a viable parameter space for a stable DM candidate that can be probed from direct search, collider and GW experiments.

description: We develop an eigenvalue-based approach for the stability assessment and stabilization of linear systems with multiple delays and periodic coefficient matrices. Delays and period are assumed commensurate numbers, such that the Floquet multipliers can be characterized as eigenvalues of the monodromy operator and by the solutions of a finite-dimensional non-linear eigenvalue problem, where the evaluation of the characteristic matrix involves solving an initial value problem. We demonstrate that such a dual interpretation can be exploited in a two-stage approach for computing dominant Floquet multipliers, where global approximation is combined with local corrections. Correspondingly, we also propose two novel characterizations of left eigenvectors. Finally, from the nonlinear eigenvalue problem formulation, we derive computationally tractable expressions for derivatives of Floquet multipliers with respect to parameters, which are beneficial in the context of stability optimization. Several numerical examples show the efficacy and applicability of the presented results.

description: Crystal fields occur due to a potential difference between chemically different atomic species. In Van-der-Waals heterostructures such fields are naturally present perpendicular to the planes. It has been realized recently that twisted graphene multilayers provide powerful playgrounds to engineer electronic properties by the number of layers, the twist angle, applied electric biases, electronic interactions and elastic relaxations, but crystal fields have not received the attention they deserve. Here we show that the bandstructure of large-angle twisted double bilayer graphene is strongly modified by crystal fields. In particular, we experimentally demonstrate that twisted double bilayer graphene, encapsulated between hBN layers, exhibits an intrinsic bandgap. By the application of an external field, the gaps in the individual bilayers can be closed, allowing to determine the crystal fields. We find that crystal fields point from the outer to the inner layers with strengths in the bottom (top) bilayer of -0.13 V/nm (0.12 V/nm). We show both by means of first principles calculations and low energy models that crystal fields open a band gap in the groundstate. Our results put forward a physical scenario in which a crystal field effect in carbon substantially impacts the low energy properties of twisted double bilayer graphene, suggesting that such contributions must be taken into account in other regimes to faithfully predict the electronic properties of twisted graphene multilayers.
Do we have any hope of detecting scattering between dark energy and baryons through cosmology?

description: We consider the possibility that dark energy and baryons might scatter off each other. The type of interaction we consider leads to a pure momentum exchange, and does not affect the background evolution of the expansion history. We parametrize this interaction in an effective way at the level of Boltzmann equations. We compute the effect of dark energy-baryon scattering on cosmological observables, focusing on the Cosmic Microwave Background (CMB) temperature anisotropy power spectrum and the matter power spectrum. Surprisingly, we find that even huge dark energy-baryon cross-sections $σ_{xb} \sim {\cal O}({\rm b})$, which are generically excluded by non-cosmological probes such as collider searches or precision gravity tests, only leave an insignificant imprint on the observables considered. In the case of the CMB temperature power spectrum, the only imprint consists in a sub-percent enhancement or depletion of power (depending whether or not the dark energy equation of state lies above or below $-1$) at very low multipoles, which is thus swamped by cosmic variance. These effects are explained in terms of differences in how gravitational potentials decay in the presence of a dark energy-baryon scattering, which ultimately lead to an increase or decrease in the late-time integrated Sachs-Wolfe power. Even smaller related effects are imprinted on the matter power spectrum. The imprints on the CMB are not expected to be degenerate with the effects due to altering the dark energy sound speed. We conclude that, while strongly appealing, the prospects for a direct detection of dark energy through cosmology do not seem feasible when considering realistic dark energy-baryon cross-sections. As a caveat, our results hold to linear order in perturbation theory.

description: In this work, we introduce the Global Planar Convolution module as a building-block for fully-convolutional networks that aggregates global information and, therefore, enhances the context perception capabilities of segmentation networks in the context of brain tumor segmentation. We implement two baseline architectures (3D UNet and a residual version of 3D UNet, ResUNet) and present a novel architecture based on these two architectures, ContextNet, that includes the proposed Global Planar Convolution module. We show that the addition of such module eliminates the need of building networks with several representation levels, which tend to be over-parametrized and to showcase slow rates of convergence. Furthermore, we provide a visual demonstration of the behavior of GPC modules via visualization of intermediate representations. We finally participate in the 2018 edition of the BraTS challenge with our best performing models, that are based on ContextNet, and report the evaluation scores on the validation and the test sets of the challenge.

description: The metallic conductivity of dilute two-dimensional holes in a GaAs HIGFET (Heterojunction Insulated-Gate Field-Effect Transistor) with extremely high mobility and large $r_{s}$ is found to have a linear dependence on temperature, consistent with the theory of interaction corrections in the ballistic regime. Phonon scattering contributions are negligible in the temperature range of our interest, allowing comparison between our measured data and theory without any phonon subtraction. The magnitude of the Fermi liquid interaction parameter $F_{0}^σ$ determined from the experiment, however, decreases with increasing $r_{s}$ for $r_{s}\agt22$, a behavior unexpected from existing theoretical calculations valid for small $r_{s}$.

description: Does the provision of livestock insurance raise the unintended consequence of stimulating excessive herd accumulation and less environmentally-sustainable herd movement patterns? The impact of insurance is theoretically ambiguous: if precautionary savings motives for holding livestock assets dominate, then we would expect to see households that receive index insurance reduce herd sizes and move less intensively. However if risk-adjusted investment motives dominate then we would expect them to build herds and move more. “Behavioural” or norm-based responses are also possible. To test between these theoretical possibilities we use the randomized provision of livestock insurance paired with novel, high frequency data collection. The results suggest that in the presence of insurance pastoralists accumulate larger herds, and move more intensively. This has implications for the potential ecological impacts scaling up of index insurance programs on the pastoralist rangelands, and for microinsurance and pastoralism more broadly.

Weakly-coupled stealth solution in scordatura degenerate theory

description: In scalar-tensor theories we revisit the issue of strong coupling of perturbations around stealth solutions, i.e.\ backgrounds with the same forms of the metric as in General Relativity but with non-trivial configurations of the scalar field. The simplest among them is a stealth Minkowski (or de Sitter) solution with a constant, timelike derivative of the scalar field, i.e.\ ghost condensation. In the decoupling limit the effective field theory (EFT) describing perturbations around the stealth Minkowski (or de Sitter) solution shows the universal dispersion relation of the form $ω^2 = αk^4/M^2$, where $M$ is a mass scale characterizing the background scalar field and $α$ is a dimensionless constant. Provided that $α$ is positive and of order unity, a simple scaling argument shows that the EFT is weakly coupled all the way up to $M$. On the other hand, if the structure of the underlining theory forces the perturbations to follow second-order equations of motion then $α=0$ and the dispersion relation loses dependence on the spatial momentum. This not only explains the origin of the strong coupling problem that was recently pointed out in a class of degenerate theories but also provides a hint for a possible solution of the problem. We then argue that a controlled detuning of the degeneracy condition, which we call scordatura, renders the perturbations weakly coupled without changing the properties of the stealth solutions of degenerate theories at astrophysical scales.

description: This paper examines partial agricultural land and labour productivity in 1975 and 1980, for different world regions. The results suggest that land and labour productivity are higher in developed countries relative to developing countries. However, agricultural labour productivity differences are more marked than those for agricultural land productivity. The productivity values for 1975 and 1980 indicate a widening of productivity differences, more so in the case of agricultural labour than land. The paper also proposes an alternative approach to estimating agricultural land and labour productivity. This approach, which regresses agricultural labour productivity on a given level of agricultural land productivity, suggests a narrowing of agricultural land productivity differences, relative to the initial approach, across Africa, Asia and Europe during the 1975-1980 period. A brief discussion of the agricultural development policy implications of the results concludes the paper.

description: We present a photometric investigation of the globular cluster population of NGC 1399, the central galaxy in the Fornax cluster, in Washington C and Kron R filters within a field of 36'x36'. This is the largest area around this galaxy ever studied with CCD photometry. The cluster system of NGC 1399 is found to extend further than 100 kpc away from the galaxy. The color distribution exhibits a pronounced bimodality. Within a radial distance of about 55 kpc, the red clusters are more strongly concentrated to the center than the blueclusters. At larger radii, the surface density profiles of the clusters are indistinguishable and match well the distribution of the galaxy light. Over the entire radial distance range, the surface brightness profile of NGC 1399 can be very well fitted by a power law with an exponent of -1.85 and a core radius of 3.3". No steepening of the luminosity profile can be detected at large radii. We suggest that the power law profile of NGC 1399 results from the galaxy being embedded in a large dark matter halo, which prevents the stellar density profile from steepening outwards. The cluster system contains 6450+-700 clusters and the specific frequency is found to be 5.1+-1.2 in the V band. While NGC 1399 shows a pronounced color gradient. Using simple assumptions about the underlying population that formed during the same star formation event as the globular clusters, we presenta model in which we use radially changing local specific frequencies for the red and blue subpopulations to fit the observations. We find that within 7' the required specific frequency of the blue clusters alone is a factor of approximately 3 larger than that of the red ones. Outside this radius however, both populations have a high local specific frequency of around 10.

description: This article aims to study students’ memorization skills on the five basics of tajweed when reciting the Quran. This study uses a quantitative approach in the form of pre and post-tests on 10 form 2 students (DLP) from Sekolah Menengah Kebangsaan Panglima Bukit Gantang, Parit Buntar, Perak. Before the researcher introduces a new method of teaching tajweed, the researcher must first detect the weaknesses of the students. A preliminary survey was done by checking students’ reciting during teaching sessions and it was found that most students are not able to memorize the five basics of tajweed apart from there are many errors in reciting. So, the researcher introduced the method of the right-hand finger to ensure that students can memorize the five basics of tajweed and recite the holy Quran well. The findings of the study show that students are not only able to memorize tajweed but can also recognize the types of recitation. The findings of this study also contribute to the basic information on the function of tanween (ًٌٍ ) and nun sakinah (نْ). The right-handed finger method has its advantages and this method needs to be expanded as a teaching aid in the mainstream.
(Artikel ini bertujuan mengkaji kemahiran mengingat pelajar terhadap lima hukum asas tajwid ketika mentilawahkan al-Quran. Kajian ini menggunakan pendekatan kuantitatif berbentuk ujian pra dan pasca ke atas 10 orang pelajar tingkatan 2 (DLP) dari Sekolah Menengah Kebangsaan Panglima Bukit Gantang, Parit Buntar, Perak. Sebelum pengkaji memperkenalkan kaedah pengajaran tajwid yang baharu, pengkaji perlu mengesan terlebih dahulu kelemahan pelajar. Tinjauan awal dilakukan dengan menyemak bacaan pelajar ketika waktu pengajaran dan didapati kebanyakan pelajar tidak mampu mengingat lima hukum asas tajwid selain terdapat banyak kesalahan dalam pembacaan. Jadi, pengkaji memperkenalkan kaedah jari tangan kanan bagi memastikan pelajar boleh mengingat lima hukum asas tajwid dan membaca al-Quran dengan baik. Dapatan kajian menunjukkan bahawa, pelajar bukan hanya mampu mengingat hukum-hukum tajwid malah dapat mengkategorikan jenis-jenis bacaan. Dapatan kajian ini juga turut menyumbang kepada maklumat asas mengenai fungsi tanwin (ًٌٍ ) dan nun sakinah (نْ). Kaedah jari tangan kanan mempunyai kelebihan yang tersendiri dan kaedah ini perlu diperluaskan sebagai alat bantu mengajar dalam arus perdana)

description: Cropping intensity in the cotton-wheat areas of Pakistan's Punjab is well below its potential, and also significantly lower than in neighbouring areas of India's Punjab. Analysis of annual cropping intensity indicates that access to irrigation water is the major factor explaining differences in cropping intensity in a cross-section of farmers. Ownership of a tractor plays a lesser role in increasing cropping intensity, although official credit policy has emphasized tractorization over investments in tubewells. Analysis of season-specific cropping intensity also indicates that lack of appropriate varieties for double cropping also constrain cropping intensity. It is estimated that cropping intensity could be increased by at least 30% through policies directed at improving water supplies and by promoting research on earlier varieties of cotton, maize and oilseeds.

description: Previous stability analysis of NSTX equilibrium with lithium-conditioning demonstrates that the enhanced resistivity due to the increased effective charge number Zeff (i.e. increased impurity level) can provide a stabilizing effect on low-n edge localized modes (Banerjee et al 2017 Nucl. Fusion 24 054501). This paper extends the resistivity stabilizing effect to the intermediate-n peeling-ballooning (PB) instabilities with the linear stability analysis of EAST high-confinement mode equilibria in NIMROD two-fluid calculations. However, the resistivity stabilizing effect on PB instabilities in the EAST tokamak appears weaker than that found in NSTX. This work may give better insight into the physical mechanism behind the beneficial effects of impurity on the pedestal stability.

description: This paper analyzes the future prospects of carbon capture technologies. The first part of the analysis presents and discusses the results of an expert elicitation survey on a broad range of carbon capture options. The survey collected probabilistic estimates on the future values of energy penalty under three different scenarios of R&D investments and climate policies from twelve leading European experts from both academia and industry. In the second part of the analysis, the elicitation results are used as input to an integrated assessment model. This allows us to evaluate the potentials of success of this technology within a broad mitigation portfolio of options and under different policy assumptions, in an intertemporal optimizing setting. Both parts of the work provide results that are of interest to policy-makers, integrated-assessment and energy modelers.

description: In recent years, a second fluid-fluid phase transition has been reported in several materials at pressures far above the usual liquid-gas phase transition. In this paper, we introduce a new model of this behavior based on the Lennard-Jones interaction with a modification to mimic the different kinds of short-range orientational order in complex materials. We have done Monte Carlo studies of this model that clearly demonstrate the existence of a second first-order fluid-fluid phase transition between high- and low-density liquid phases.

description: We investigate the efficiency of k-means in terms of both statistical and computational requirements. More precisely, we study a Nyström approach to kernel k-means. We analyze the statistical properties of the proposed method and show that it achieves the same accuracy of exact kernel k-means with only a fraction of computations. Indeed, we prove under basic assumptions that sampling $\sqrt{n}$ Nyström landmarks allows to greatly reduce computational costs without incurring in any loss of accuracy. To the best of our knowledge this is the first result of this kind for unsupervised learning.

description: We present a many body approach for non-equilibrium behavior and self-generated glassiness in strongly correlated quantum systems. It combines the dynamical mean field theory of equilibrium systems with the replica theory for classical glasses without quenched disorder. We apply this approach to study a quantized version of the Brazovskii model and find a self-generated quantum glass that remains in a quantum mechanically mixed state as T -> 0. This quantum glass is formed by a large number of competing states spread over an energy region which is determined within our theory.

description: Adoption of agricultural production technologies in developing countries is influenced by a wide range of economic and social factors as well as physical and technical aspects of farming and the risk attitude of farmers. It is important to understand the role of these factors to ensure the development of appropriate technologies and the design of successful development projects. This study examines the impact of such factors on the adoption of single-ox, fertilizer and pesticide technologies as part of a post-drought recovery project in Tegulet-Bulga district in Ethiopia. Models to evaluate the probability of adoption are specified for the respective technologies and are estimated using a logit maximum likelihood procedure. results indicate that the most significant variable affecting the probability of adoption of all three technologies is farm size; the impact is negative for single-ox technology and positive for fertilizer and pesticide use. Economic factors such as income, wealth and debt generally exhibit statistically significant influence on the adoption of single-ox and pesticide technologies as do family size, access to outside information, education and experience. The effect of socio-economic factors on adoption of fertilizer and pesticide technologies is greater in the area which has more access to outside information and off-farm activities (Ankober) than in more 'self-contained' area (Seladengay). The impact of the degree of risk aversion of farmers is found to be significant and negative for single-ox technology in both areas, and for fertilizer and pesticide technologies in only one area. The predicted probabilities of technology adoption by an average farmer are found to increase dramatically with the level of education and access or exposure to outside information.

description: We have studied scalar potentials V of gauged N=8,4,2 supergravities in d=4. Extrema of these potentials may correspond to de Sitter, anti de Sitter and Minkowski vacua. All de Sitter extrema that we have studied correspond to unstable maximum/saddle points with negative curvature |V''|=2V for the fields canonically normalized at the extremum. This is equivalent to the relation |m^2| =|R|/2 = 6H^2 for the tachyonic mass m, the curvature scalar R, and the Hubble constant H. This prevents the use of de Sitter extrema for slow-roll inflation in the early universe, which would require |V''| \ll V . Moreover, in all models that we were able to analyse the potential is unbounded from below. On the other hand, barring the question how realistic such models could be, one can use them for the description of the accelerated expansion of the universe at the present epoch. This is related to a novel possibility of the fast-roll inflation with |V''| > V . We also display some potentials that have flat directions with vanishing cosmological constant, and discuss their possible cosmological implications.

description: We examine in detail the dynamical structure of an elliptical galaxy simulated in the Lambda CDM scenario. The morphology of the galaxy evolves dramatically over time in response to the mode and timing of mass accretion; smooth deposition of cooled gas leads to the formation of centrifugally supported disks, whilst major mergers disperse stellar disks into spheroids. These two modes of accretion alternate successively until z~0.6, when the galaxy undergoes one last major (1:2) merger that consumes much of the remaining gas into stars. Little gas cools and accretes subsequently and, as a result, most stars at z=0 are in a spheroidal component that resembles present-day elliptical galaxies. Dynamically, the galaxy is well approximated by an E4 oblate rotator. Boxy isophotes are obtained when the galaxy is seen face-on and Vrot/sigma<<1. On the other hand, disky isophotes are found for inclinations which maximize Vrot/sigma. The line-of-sight velocity distribution is nearly Gaussian at all radii. The sign of the Gauss-Hermite skewness parameter h3 is anti-correlated with the apparent sense of rotation, in agreement with observed trends. The simulated galaxy has much higher effective surface brightness than normal ellipticals of similar luminosity, in a way reminiscent of the less common type of compact ellipticals. Our simulation shows that repeated episodes of dissipational collapse, followed by merger events, lead to stellar spheroids that are only mildly triaxial and of relatively simple kinematic structure. This is in better agreement with observation than earlier models based on dissipationless mergers of stellar disks, and a positive step towards reconciling the observed structure of ellipticals with the hierarchical merging scenario.
