description: The transverse mass spectra and mid-rapidity yields for $Ξ$s and $Ω$s plus their anti-particles are presented. The 10% most central collision yields suggest that the amount of multi-strange particles produced per produced charged hadron increases from SPS to RHIC energies. A hydrodynamically inspired model fit to the spectra, which assumes a thermalized source, seems to indicate that these multi-strange particles experience a significant transverse flow effect, but are emitted when the system is hotter and the flow is smaller than values obtained from a combined fit to $π$, K, p and $Λ$s.

description: The decoherence times of orthogonally phased components of the optical transition dipole moment in a two-level system have been observed to differ by an order of magnitude. This phase anisotropy is observed in coherent transient experiments where an optical driving field is present during extended periods of decoherence. The decoherence time of the component of the dipole moment in phase with the driving field is extended compared to T_2, obtained from two-pulse photon echoes, in analogy with the spin locking technique of NMR.

description: We investigate the density structure of the interstellar medium using new high-resolution maps of the 8 micron, 24 micron, and 70 micron surface brightness towards a molecular cloud in the Gum Nebula, made as part of the Spitzer Space Telescope Galactic First Look Survey. The maps are correlated with 100 micron images measured with IRAS. At 24 and 70 micron, the spatial power spectrum of surface brightness follows a power law with spectral index -3.5. At 24 micron, the power law behavior is remarkably consistent from the 0.2 degree size of our maps down to the 5 arcsecond spatial resolution. Thus, the structure of the 24 micron emission is self-similar even at milliparsec scales. The combined power spectrum produced from Spitzer 24 micron and IRAS 25 micron images is consistent with a change in the power law exponent from -2.6 to -3.5. The decrease may be due to the transition from a two-dimensional to three-dimensional structure. Under this hypothesis, we estimate the thickness of the emitting medium to be 0.3 pc.

description: We have investigated the peculiar structure of charge and spin ordering in the half-doped layered perovskite oxide La$_{1.5}$Sr$_{0.5}$CoO$_4$ by elastic neutron scattering. Two samples with different preparation histories were studied. We find that the generic features of the ordered states, such as their short-range, glassy nature and the spin incommensurability, are sample-independent. At the same time, some subtle features of the ordered phases, such as the correlation lengths, differ.

description: Constructing heterostructures of a topological insulator (TI) with an undoped magnetic insulator (MI) is a clean and versatile approach to break the time-reversible symmetry in the TI surface states. Despite a lot of efforts, the strength of interfacial magnetic proximity effect (MPE) is still too weak to achieve the quantum anomalous Hall effect and many other topological quantum phenomena. Recently, a new approach based on intercalation of atomic layers of MI, referred to as magnetic extension, was proposed to realize strong MPE [2D Mater. 4, 025082(2017)]. Motivated by this proposal, here, we study a magnetic extension system prepared by molecular beam epitaxy growth of MnSe thin films on topological insulator (Bi,Sb)2Te3. Direct evidence is obtained for intercalation of MnSe atomic layer into a few quintuple layers of (Bi,Sb)2Te3, forming either a double magnetic septuple layer (SL) or an isolated single SL at the interface, where one SL denotes a van der Waals building block consisting of B-A-B-Mn-B-A-B (A=Bi1-xSbx, B= Te1-ySey). The two types of interfaces (namely TI/mono-SL and TI/bi-SL) have different MPE, which is manifested as distinctively different transport behaviors. Specifically, the mono-SL induces a spinflip transition with a sharp change at small magnetic field in the anomalous Hall effect of TI layers, while the bi-SL induces a spin-flop transition with a slow change at large field. Our work demonstrates a useful platform to realize the full potential of the magnetic extension approach for pursuing novel topological physics and related device applications.

description: In this work, we propose a novel approach that predicts the relationships between various entities in an image in a weakly supervised manner by relying on image captions and object bounding box annotations as the sole source of supervision. Our proposed approach uses a top-down attention mechanism to align entities in captions to objects in the image, and then leverage the syntactic structure of the captions to align the relations. We use these alignments to train a relation classification network, thereby obtaining both grounded captions and dense relationships. We demonstrate the effectiveness of our model on the Visual Genome dataset by achieving a recall@50 of 15% and recall@100 of 25% on the relationships present in the image. We also show that the model successfully predicts relations that are not present in the corresponding captions.

description: Technological change in agriculture in climate risk exposed developing countries requires for three major reasons: First, the increased climate risk and increase the need for new agricultural technologies that are more robust to such variability. Second, a need for land use intensification to feed the growing populations and third, economic transformation that creates an opportunity for market-oriented production that is more focused on the production of crops for market. This study emphasizes to assess factors associated with the extent of and intensity of adoption of three farm technologies (high yield wheat, drought tolerant teff, and cash crops) in the semi-arid of northern Ethiopia. We estimate determinants of adoption of the three technologies using double hurdle models. We apply correlated random effects with control function approach to control for possible endogeneity associated with access to the technologies. Results show that high population density has a positive and significant effect on the adoption decision of improved wheat and, irrigation has positive and significant effect on adoption of cash crops. Adoption of drought-tolerant teff is access constrained. Hence, increasing access to drought-tolerant teff and promoting irrigation appears to be adoption stimulants of drought-resistant teff and cash crops in a climate risk environment.

description: For this project, our research question was “How does the duration of time spent in outdoor green spaces affect students’ level of stress while studying?” Our hypothesis is that students who study with the presence of green space would be less stressed than those who study without the presence of green space. In order to test our claim, we performed a correlational study. We had a total of 135 participants respond via a self-report survey. The independent variable was the duration of time spent studying outdoors and the dependent variable was the level of stress after studying. The participants’ stress levels were measured using the Depression Anxiety Stress Scale. Based on the data that was collected, we found no correlation between the duration of time spent studying in outdoor green spaces and the individual’s level of stress. At the same time, we observed that participants were more likely to study in outdoor green spaces if they had more information on the location and its availability.

description: Abstract This study investigated the vertical distribution and temporal changes of limpet species. Species diversity was measured in terms of number of limpet species. Sampling was conducted at Dwesa-Cwebe Nature Reserve and two sites with approximately 1.5 km apart were selected. In each site, three rock pools were chosen: MLWS (mid low water shore), MHWS (mid high water shore) and HWS (high water shore). ANOVA results revealed that no significant differences on species diversity, implying the importance of biological processes such as recruitment rather than physical processes. Despite seasonal differences in environmental conditions, the limpet species occurred across the three shore heights. Although there were significant differences in mean sizes (shell lengths) in three (Cellana capensis, Siphonaria serrata Helcion concolor) out of seven limpet species found, there were significant interaction of season and site, indicating that the mean shell length had significant effects in some seasons but not others. Where there were significant differences, mean shell lengths decreased with a decrease in shore height and vice versa. Mean temperatures and salinities increased significantly with an increase in height. They also showed significant differences among seasons and between sites, suggesting temporal and spatial variations on small scales (1.5 km).

description: The technique of dimensional reduction was used in a recent paper (Zanchin et al, Phys. Rev. D66, 064022,(2002)) where a three-dimensional (3D) Einstein-Maxwell-Dilaton theory was built from the usual four-dimensional (4D) Einstein-Maxwell-Hilbert action for general relativity. Starting from a class of 4D toroidal black holes in asymptotically anti-de Sitter (AdS) spacetimes several 3D black holes were obtained and studied in such a context. In the present work we choose a particular case of the 3D action which presents Maxwell field, dilaton field and an extra scalar field, besides gravity field and a negative cosmological constant, and obtain new 3D static black hole solutions whose horizons may have spherical or planar topology. We show that there is a 3D static spherically symmetric solution analogous to the 4D Reissner-Nordström-AdS black hole, and obtain other new 3D black holes with planar topology. From the static spherical solutions, new rotating 3D black holes are also obtained and analyzed in some detail.

description: Physical embodiment is a required component for robots that are structurally coupled with their real-world environments. However, most socially interactive robots do not need to physically interact with their environments in order to perform their tasks. When and why should embodied robots be used instead of simpler and cheaper virtual agents? This paper reviews the existing work that explores the role of physical embodiment in socially interactive robots. This class consists of robots that are not only capable of engaging in social interaction with humans, but are using primarily their social capabilities to perform their desired functions. Socially interactive robots provide entertainment, information, and/or assistance; this last category is typically encompassed by socially assistive robotics. In all cases, such robots can achieve their primary functions without performing functional physical work. To comprehensively evaluate the existing body of work on embodiment, we first review work from established related fields including psychology, philosophy, and sociology. We then systematically review 65 studies evaluating aspects of embodiment published from 2003 to 2017 in major peer-reviewed robotics publication venues. We examine relevant aspects of the selected studies, focusing on the embodiments compared, tasks evaluated, social roles of robots, and measurements. We introduce three taxonomies for the types of robot embodiment, robot social roles, and human-robot tasks. These taxonomies are used to deconstruct the design and interaction spaces of socially interactive robots and facilitate analysis and discussion of the reviewed studies. We use this newly-defined methodology to critically discuss existing works, revealing topics within embodiment research for social interaction, assistive robotics, and service robotics.

description: We show that the renormalization group flows of the massless superstring modes in the presence of fluctuating D-branes satisfy the equations of fluid dynamics.In particular, we show that the D-brane's U(1) field is related to the velocity function in the Navier-Stokes equation while the dilaton plays the role of the passive scalar advected by the turbulent flow. This leads us to suggest a possible isomorphism between the off-shell superstring theory in the presence of fluctuating branes and the fluid mechanical degrees of freedom.

description: Agriculture is unique from most other sectors, because of its strong reliance on weather inputs and seasonal requirement for production factors. The seasonality of labour markets is a well-known issue and is particularly relevant for rural livelihoods in developing countries, where a large share of the population relies on labour intensive agriculture. All the more astonishing is the fact, that seasonality of labour markets has hardly been incorporated in economy-wide models such as computable general equilibrium (CGE) models. This study develops the first national CGE model framework with an explicit depiction of seasonal labour markets. In order to demonstrate the relevance of seasonality for model outcomes the model is applied to a case study of Bhutan being affected by an increase in cereal prices. If the seasonality of labour markets is accounted for we find that the price shock results in a substantially lower supply response of the agriculture sector and that ignoring the seasonality of labour markets results in an overestimation of positive welfare effects for farm households. Furthermore, we find that incorporating seasonal labour results in a more accurate understanding of resource constraints, which can benefit the application of models for policy analysis.

description: Heat assisted magnetic recording (HAMR) technology represents the most promising candidate to replace the current perpendicular recording paradigm to achieve higher storage densities. To better understand HAMR dynamics in granular media we need to describe accurately the magnetisation dynamics up to temperatures close to the Curie point. To this end we propose a multiscale approach based on the micromagnetic Landau-Lifshitz-Bloch (LLB) equation of motion parametrised using atomistic calculations. The LLB formalism describes the magnetisation dynamics at finite temperature and allows to efficiently simulate large system sizes and long time scales. Atomistic simulations provide the required temperature dependent input quantities for the LLB equation, such as the equilibrium magnetisation and the anisotropy, and can be used to capture the detailed magnetisation dynamics. The multiscale approach makes possible to overcome the computational limitations of atomistic models in dealing with large systems, such as a recording track, while incorporating the basic physics of the HAMR process. We investigate the magnetisation dynamics of a single FePt grain as function of the properties of the temperature profile and applied field and test the micromagnetic results against atomistic calculations. Our results prove the appropriateness and potential of the approach proposed here where the granular model is able to reproduce the atomistic simulations and capture the main properties of a HAMR medium.

description: In this article we classify quadruple Galois canonical covers $ϕ$ of singular surfaces of minimal degree. This complements the work done in math.AG/0302045, so the main output of both papers is the complete classification of quadruple Galois canonical covers of surfaces of minimal degree, both singular and smooth. Our results show that the covers $X$ studied in this article are all regular surfaces and form a bounded family in terms of geometric genus $p_g$. In fact, the geometric genus of $X$ is bounded by 4. Together with the results of Horikawa and Konno for double and triple covers, a striking numerology emerges that motivates some general questions on the existence of higher degree canonical covers. In this article, we also answer some of these questions. The arguments to prove our results include a delicate analysis of the discrepancies of divisors in connection with the ramification and inertia groups of $ϕ$.

description: The NUGA project is the first high-resolution (0.5''-1'') CO survey of low luminosity AGN including the full sequence of activity types (Seyfert 1--2 and LINERs). NUGA aims to study systematically the different mechanisms for gas fueling of the AGN. In order to reach the critical spatial scales for AGN feeding (<100 pc), we are undertaking high-resolution observations, made at the Plateau de Bure Interferometer, to achieve a sharp view of the distribution and kinematics of molecular gas. In this talk we discuss the latest results of this survey which now includes newly acquired subarcsec resolution observations for 5 targets of our sample. The large variety of circumnuclear disk morphologies found in NUGA galaxies (m=1, m=2 and m=0-type gravitational instabilities) is a challenging result that urges the refinement of current dynamical models.

description: It seems quite obvious that both the vaḍukar - the aborigines – and the Deccan caḍḍī migrated to the coast from trans-Sahyādrī Koṁkaṇ; most probably the former had settled on the available land on the coast very early. In fact, the movement seems to have been first within the Deccan, from the rain deficient plateau in the east to the wetter foot valleys of the Sahyādrī; and then up the eastern slopes and down the western slopes.

description: El objetivo de este artículo consiste en realizar una exposición teórica en torno al aspecto de la oralidad en el romancero tradicional y las condiciones de pervivencia y de renovación del discurso del romance a través de la dinámica de versiones y variantes. La transmisión de carácter oral permite la concepción aperturista del modelo romancístico mediante la concatenación de los discursos en virtud de los constantes procesos de producción y de recepción por parte de los diversos recitadores o cantores. En aras del discernimiento del sentido profundo de la vida folklórica del romance, este trabajo contempla tres propósitos fundamentales desde el marco teórico-metodológico de la Retórica cultural: 1) aborda las relaciones del romancero tradicional con la Retórica y la Retórica cultural; 2) revisa los niveles de articulación poética del romancero propuestos por Catalán —la fábula, la intriga y el modelo actancial— y los conecta con los conceptos clave de la Teoría del siglo XX en el ámbito de los estudios narratológicos, y 3) explica el componente comparatista y el fenómeno de la intertextualidad en el romancero tradicional a la luz de la Retórica cultural.

Quantum-mechanical effect in atomically thin MoS2 FET

description: Two-dimensional (2D) layered materials-based field-effect transistors (FETs) are promising for ultimate scaled electron device applications because of the improved electrostatics to atomically thin body thickness. However, compared with the typical thickness of ~5-nm for Si-on-insulator (SOI), the advantage of the ultimate thickness limit of monolayer for the device performance has not been fully proved yet, especially for the on-state at the accumulation region. Here, we present much stronger quantum-mechanical effect at the accumulation region based on the C-V analysis for top-gate MoS2 FETs. The self-consistent calculation elucidated that the electrons are confined in the monolayer thickness, unlike in the triangle potential formed by the electric field for SOI, the gate-channel capacitance is ideally maximized to the gate insulator capacitance since the capacitive contribution of the channel can be neglected due to the negligible channel thickness. This quantum-mechanical effect agreed well with the experimental results. Therefore, monolayer 2D channels are suggested to be used to enhance the on-current as well as the gate modulation ability.

description: We present a novel pressure-based method for weakly compressible multiphase flows, based on a non-equilibrium Baer and Nunziato-type model. In this work, we describe the hyperbolic operator, thus we do not consider relaxation terms. The acoustic part of the governing equations is treated implicitly to avoid the severe restriction on the time step imposed by the CFL condition at low-Mach. Particular care is taken to discretize the non-conservative terms to avoid spurious oscillations across multi-material interfaces. The absence of oscillations and the agreement with analytical or published solutions is demonstrated in simplified test cases, which confirm the validity of the proposed approach as a building block on which developing more accurate and comprehensive methods.

description: Governance of economic exchange can be realized through various coordination mechanisms and thus, farmers must choose alternative mechanism through which to channel their primary commodity. This paper looks at two coordination mechanisms and returns accruable from farmer participation in either spot market arrangement or bilateral contract arrangement, or both. Participation in two coordination mechanisms is observed as safe-guard of expected benefits against market uncertainty. Based on survey data from 349 smallholder farmers in central Uganda, we find that farmers derive higher benefit from participation in bilateral market coordination compared to spot market coordination. It is shown that there the difference in yield among the farmer categories is insignificant and that farmers who participate in both spot market and bilateral contracts earn twice compared to farmers under only spot markets. For returns to labor, every dollar cost of labor yields US$ 1.1 under single market coordination and about US$ 1.5 under double market coordination system. The trade-off analysis showed that adoption rate for bilateral contract system is about 56.5% and there are gains in adoption of bilateral contract market coordination. Thus, promotion of bilateral contracts requires provisions that allow farmers to participate in more than one markets while limiting contract reneging.

description: As 2050 drawers nearer, global food production faces growing demand for food, challenges from climate change and globalization. As ensuring food security for a growing global population will require innovative and sustainable solutions, research in this field endeavors to understand the landscape of food security in the coming decades. As such, global food security and computable general equilibrium modelling have partnered to help assess how these challenges will affect our ability to produce food. However, knowledge and research gaps remain. Thus, this paper innovatively highlights that food security analysis using computable general equilibrium modelling can be enhanced by filling one part of the mineral resource gap by including the critical element phosphorus. This paper provides a detailed literature review on current approaches in phosphorus modeling and their contributions to economic modeling and how current knowledge gaps can be bridged by including phosphorus into food security analyses using computable general equilibrium modeling.

description: Layered singlet paired superconductors with disorder and broken time reversal symmetry are studied. The phase diagram demonstrates charge-spin separation in transport. In terms of the average intergrain transmission and the interlayer tunnelling we find quantum Hall phases with spin Hall coefficients of 0 and 2 separated by a spin metal phase. We identify a spin metal-insulator localization exponent as well as a spin conductivity exponent of ~0.9. In presence of a Zeeman term an additional phase with spin Hall coefficient of 1 appears.
