description: Bismuth iron garnet (BIG), i.e. Bi3Fe5O12, is a strong ferrimagnet that also possess outstanding magneto-optical properties such as the largest known Faraday rotation. These properties are related with the distribution of magnetic moments on octahedral and tetrahedral sites, the presence of spin gaps in the density of state and a strong spin-orbit coupling. In this work, first-principles ab initio calculations are performed to study the structural, electronic and magnetic properties of BIG using Density Functional Theory with Hubbard+U (DFT+U) correction including spin-orbit coupling and HSE06 hybrid functional. We found that the presence of spin gaps in the electronic structure results from the interplay between exchange and correlation effects and the crystal field strengths for tetrahedral and octahedral iron sublattices. The DFT+U treatment tends to close the spin-gaps for larger U due to over-localization effects, notably in the octahedral site. On the other hand, the hybrid functional confirms the occurrences of three spin gaps in the iron states of the conduction band as expected from optical measurements. A strong exchange splitting at the top of the valence bands associated with a lone-pair type mixture of O p and Bi s,p states is also obtained. Similar exchange splitting was not previously observed for other iron based garnets, such as for yttrium iron garnet. It follows that hole doping, as obtained by Ca substitution at Bi sites, results in a full spin polarized density at the Fermi energy. This work helps to shed more light on the theoretical comprehension of the properties of BIG and opens the route towards the use of advanced Many Body calculations to predict the magneto-optical coupling effects in BIG in a direct comparison with the experimental measurements.

description: The upcoming new generation of optical spectrographs on four-meter-class telescopes will provide invaluable information for reconstructing the history of star formation in individual galaxies up to redshifts of about 0.7. We aim at defining simple but robust and meaningful physical parameters that can be used to trace the coexistence of widely diverse stellar components: younger stellar populations superimposed on the bulk of older ones. We produce spectra of galaxies closely mimicking data from the forthcoming Stellar Populations at intermediate redshifts Survey (StePS), a survey that uses the WEAVE spectrograph on the William Herschel Telescope. First, we assess our ability to reliably measure both ultraviolet and optical spectral indices in galaxies of different spectral types for typically expected signal-to-noise levels. Then, we analyze such mock spectra with a Bayesian approach, deriving the probability density function of r- and u-band light-weighted ages as well as of their difference. We find that the ultraviolet indices significantly narrow the uncertainties in estimating the r- and u-band light-weighted ages and their difference in individual galaxies. These diagnostics, robustly retrievable for large galaxy samples even when observed at moderate signal-to-noise ratios, allow us to identify secondary episodes of star formation up to an age of ~0.1 Gyr for stellar populations older than ~1.5 Gyr, pushing up to an age of ~1 Gyr for stellar populations older than ~5 Gyr. The difference between r-band and u-band light-weighted ages is shown to be a powerful diagnostic to characterize and constrain extended star-formation histories and the presence of young stellar populations on top of older ones. This parameter can be used to explore the interplay between different galaxy star-formation histories and physical parameters such as galaxy mass, size, morphology, and environment.

Year: 2003

subject: FOS: Physical sciences

description: Given a foreground galaxy-density field or shear field, its cross-correlation with the shear field from a background population of source galaxies scales with the source redshift in a way that is specific to lensing. Such a source-scaling can be exploited to effectively measure geometrical distances as a function of redshift and thereby constrain dark energy properties, free of any assumptions about the galaxy-mass/mass power spectrum (its shape, amplitude or growth). Such a geometrical method can yield a ~ 0.03 - 0.07 f_{sky}^{-1/2} measurement on the dark energy abundance and equation of state, for a photometric redshift accuracy of dz ~ 0.01 - 0.05 and a survey with median redshift of ~ 1. While these constraints are weaker than conventional weak lensing methods, they provide an important consistency check because the geometrical method carries less theoretical baggage: there is no need to assume any structure formation model (e.g. CDM). The geometrical method is at the most conservative end of a whole spectrum of methods which obtain smaller errorbars by making more restrictive assumptions -- we discuss some examples. Our geometrical approach differs from previous investigations along similar lines in three respects. First, the source-scaling we propose to use is less demanding on the photometric redshift accuracy. Second, the scaling works for both galaxy-shear and shear-shear correlations. Third, we find that previous studies underestimate the statistical errors associated with similar geometrical methods, the origin of which is discussed.

Limited-control optimal protocols arbitrarily far from equilibrium

description: Recent studies have explored finite-time dissipation-minimizing protocols for stochastic thermodynamic systems driven arbitrarily far from equilibrium, when granted full external control to drive the system. However, in both simulation and experimental contexts, systems often may only be controlled with a limited set of degrees of freedom. Here, going beyond slow- and fast-driving approximations employed in previous studies, we obtain exact finite-time optimal protocols for this unexplored limited-control setting. By working with deterministic Fokker-Planck probability density time evolution, we can frame the work-minimizing protocol problem in the standard form of an optimal control theory problem. We demonstrate that finding the exact optimal protocol is equivalent to solving a system of Hamiltonian partial differential equations, which in many cases admit efficiently calculatable numerical solutions. Within this framework, we reproduce analytical results for the optimal control of harmonic potentials, and numerically devise novel optimal protocols for two anharmonic examples: varying the stiffness of a quartic potential, and linearly biasing a double-well potential. We confirm that these optimal protocols outperform other protocols produced through previous methods, in some cases by a substantial amount. We find that for the linearly biased double-well problem, the mean position under the optimal protocol travels at a near-constant velocity. Surprisingly, for a certain timescale and barrier height regime, the optimal protocol is also non-monotonic in time.

description: We consider the final evolutionary stages of a neutron star-black hole pair. According to the current paradigm, such systems eventually coalesce, which in some cases is accompanied by neutron-star tidal disruption. Using analytical methods, we show that the scenario of slow (of the order of several seconds) neutron-star stripping by the black hole is also possible, depending on the system parameters (the initial masses and intrinsic angular momenta of the components, the equation of state for the neutron star). Reaching the lower mass limit (about one tenth of the solar mass), the neutron star explodes to produce a comparatively powerful electromagnetic transient. Our population calculations show that the stripping mechanism is possible in 50-90% of the cases among all coalescing neutron star-black hole pairs, depending on the model assumptions about the evolution of close binary systems (the common-envelope efficiency parameter, the supernova explosion mechanism) and the initial metallicity of the stellar population. Because of the large mass of the ejected material, the kilonova emission in this scenario has good prospects of detection.

description: We investigate the binary content of the two stellar populations that coexist in the globular cluster NGC 3201. Previous studies of binary stars in globular clusters have reported higher binary fractions in their first populations (P1, having field-like abundances) compared to their second populations (P2, having anomalous abundances). This is interpreted as evidence for the latter forming more centrally concentrated. In contrast to previous studies, our analysis focuses on the cluster centre, where comparable binary fractions between the populations are predicted because of the short relaxation times. However, we find that even in the centre of NGC 3201, the observed binary fraction of P1 is higher, (23.1 +/- 6.2)% compared to (8.2 +/- 3.5)% in P2. Our results are difficult to reconcile with a scenario where the populations only differ in their initial concentrations, but instead suggests that the populations also formed with different fractions of binary stars.

description: In Ghana, about two-third of rural households earn their livelihoods from subsistence agriculture and agricultural related activities such as agro-processing. Agro-industries add value to agricultural raw material through processing to produce marketable and usable products that brings forth profits and additional income to the producer. It is also crucial for generating employment, income opportunities and improves the quality of life of many people. Agro-processing such as palm oil and palm kernel oil processing serves as a major source of livelihood for many people in developing countries especially women. The study was carried out to find out the correlates of perceived livelihood of palm kernel oil processors at Abura, a suburb of the Cape Coast Metropolitan Assembly. All 45 palm kernel oil processors (all women) in the study area were included in the study but only 36 (80%) agreed to respond. The results showed that 69.4% % of the women involved in the palm kernel oil processing business are illiterate and are mostly married with a mean age and household size of 48 and six, respectively. The findings of the study further revealed that the majority of the respondents had been in the business for more than ten years. The results of the study showed that the palm kernel oil processors were more vulnerable to frequent breakdown of milling machine, palm kernel oil price fluctuations, high cost of palm kernels and inadequate operating capital. There was a positive relationship between the level of livelihood assets (natural, human, physical, financial, social) and age, household size and work experience. The study also indicates that as the processors accumulate more assets their perceived level of vulnerability goes down. Based on the findings of the study it is recommended that Women in Agriculture Division of the Ministry of Food and Agriculture should organize the women into cooperative group so they could sell their produce through the cooperative instead of selling on individual basis. This will help to insulate them to some extent against price fluctuations. Further, the Ministry of Trade and Industries through the Department of Cottage industries should provide the women with modern milling machines in order to reduce their vulnerability due to frequent breakdown of the current milling machines.

The vast difference between mosquito and bird lifespans, another peculiarity of the system, is shown to lead to interesting consequences regarding delay in the onset of the steady-state infection. An outline of a framework is provided to treat mosquito diffusion and bird migration.

description: Crystals of energetic materials, such as HMX, embedded in plastic binders are the building blocks of plastic-bonded explosives. Such heterogeneous energetic materials contain microstructural features such as sharp corners, interfaces between crystal and binder, intra- and extra-granular voids, and other defects. Energy localization or hotspots arise during shock interaction with the microstructural heterogeneities, leading to the initiation of PBXs. In this paper, high-resolution numerical simulations are performed to elucidate the mechanistic details of shock-induced initiation in a PBX; we examine four different mechanisms: Shock-focusing at sharp corners or edges and its dependency on the shape of the crystal, and the strength of the applied shock; debonding between crystal and binder interfaces; collapse of voids in the binder located near an HMX crystal; and the collapse of voids within HMX crystals. Insights are obtained into the relative contributions of these mechanisms to the ignition and growth of hotspots. Understanding these mechanisms of energy localization and their relative importance for hotspot formation and initiation sensitivity of PBXs will aid in the design of energetic material-driven systems with controlled sensitivity, to prevent accidental initiation and ensure reliable performance.

subject: Cassava, Heckman’s model, market participation, Uganda

description: Cassava (Manihot esculenta crantz) is a crop of global significance especially in the tropics where it is a source of food, animal feeds and industrial starch. However, the rapid Post- Harvest Physiological Deterioration (PPD), bulkiness of fresh cassava roots and high toxicity of some cassava varieties prohibits prolonged marketing and market participation of smallholder farmers. A cross-sectional study was conducted in north and north-eastern Uganda to ascertain the drivers of market participation for smallholder cassava farmers. Data were collected using pre-tested questionnaires administered to 185 randomly selected respondents and using STATA package, a two stage Heckman’s model was fitted involving a Probit model and OLS regression in the first and second stages, respectively. Results of the first stage Probit model revealed that farm land size, market distance, size of household, transport cost and off-farm annual income significantly (P<0.05) influenced the market participation decisions of smallholder cassava processors. In the OLS regression of the outcomes model, gender, market distance, contract marketing, marketing experience, education level, and land allocated to cassava production and group marketing significantly increased the sales revenues of processed cassava products. Our findings indicate that socio-economic and institutional factors are important in stimulating smallholder cassava farmers’ market participation. Therefore, policy support is needed in the areas of contract marketing, processing to prolong cassava shelf-life, strengthen market access conditions and lift smallholder farmers from income poverty.

description: We consider a system of stacked tunnel-coupled two-dimensional electron- and hole-gas layers with Rashba spin-orbit interactions subjected to a staggered Zeeman field. The interplay of different intra-layer tunnel couplings results in a phase transition to a topological insulator phase in three dimensions hosting gapless surface states. The staggered Zeeman field further enriches the topological phase diagram by generating a second-order topological insulator phase hosting gapless hinge states. The emergence of the topological phases is proven analytically in the regime of small Zeeman field and confirmed by numerical simulations in the non-perturbative region of the phase diagram. The topological phases are stable against external perturbations and disorder.

description: In our local Galactic neighborhood, molecular clouds are best studied using a combination of dust measurements, to determine robust masses, sizes and internal structures of the clouds, and molecular-line observations to determine cloud kinematics and chemistry. We present here the first results of a program designed to extend such studies to nearby galaxies beyond the Magellanic Clouds. Utilizing the wideband upgrade of the Submillimeter Array (SMA) at 230 GHz we have obtained the first continuum detections of the thermal dust emission on sub-GMC scales ($\sim$ 15 pc) within the Andromeda galaxy (M31). These include the first resolved continuum detections of dust emission from individual GMCs beyond the Magellanic Clouds. Utilizing a powerful capability of the SMA, we simultaneously recorded CO(2-1) emission with identical $(u,\,v)$ coverage, astrometry and calibration, enabling the first measurements of the CO conversion factor, $α_{\rm\,CO(2-1)}$, toward individual GMCs across an external galaxy. Our direct measurement yields an average CO--to--dust mass conversion factor of $α^\prime_{\rm CO-dust} = 0.042\pm0.018$ $M_\odot$ (K km s$^{-1}$ pc$^2$)$^{-1}$ for the $J= 2-1$ transition. This value does not appear to vary with galactocentric radius. Assuming a constant gas-to-dust ratio of 136, the resulting $α_{\rm CO}$ $=$ 5.7 $\pm$ 2.4 $M_\odot$ (K km s$^{-1}$ pc$^2$)$^{-1}$ for the 2-1 transition is in excellent agreement with that of Milky Way GMCs, given the uncertainties. Finally, using the same analysis techniques, we compare our results with observations of the local Orion molecular clouds, placed at the distance of M31 and simulated to appear as they would if observed by the SMA.

The system-environment coupling is modelled in a thermodynamically consistent way by means of a nonlocal Lindblad master equation. We show that the engine may operate in four different operation modes, depending on the various parameters, in particular it can act as a heat engine and as a refrigerator. We detect an enhancement of the thermodynamic performance as the critical point is crossed, and investigate it in detail.

description: The problem of the chemical composition gradient in the galactic disk is studied based on a sample of metallicity estimates of open star clusters, using Gaia DR2-improved distance estimates. A clearly non-monotonic variation was observed in the average metallicity of clusters with increasing galactocentric distance. One can clearly see the metallicity jump of 0.22 in [Fe/H] at a Galactocentric distance of about 9.5 kpc, which appears to be linked to the outer boundary of the thinnest and youngest component of the galactic disk. The absence of a significant metallicity gradient in the internal (R<9 kpc) and external (R>10 kpc) regions of the disk demonstrates the absence of noticeable metal enrichment at times of the order of the ages corresponding to those of the disk regions under consideration. Observational data show that the disk experiences noticeable metal enrichment only during the starburst epochs. No significant dependence was found between the average metallicity and the age of the clusters.

description: We present a detailed comparison of a variety of predictions for diffractive light vector meson production with the data collected at the HERA collider. All our calculations are performed within a dipole model framework and make use of different models for the meson light-cone wavefunction. There are no free parameters in any of the scenarios we consider. Generally we find good agreement with the data using rather simple Gaussian motivated wavefunctions in conjunction with dipole cross-sections which have been fitted to other data.

description: Consumers in sub-Saharan Africa derive a major portion of their diets from vegetables which have been found to play a significant role in human nutrition, especially as important sources of vitamins, essential minerals, dietary fiber, and various phytochemicals. However, the consumption of vegetables is still below the recommended level by WHO and FAO. This study examined the factors that influence the nutrition knowledge, frequency intake and attitudes of consumers towards Traditional African Vegetables (TAVs) consumption. Generalized poison and factor analysis were used for analysis. Data were collected from purposively selected 262 consumers in Tengeru, Embaseny and Bangata markets in Arumeru District, Tanzania. Results showed that years of schooling, age and nature of occupation influenced consumer’s nutrition knowledge. Intake Frequency of TAVs was influenced by distance to the market, taboos, price of TAVs and consumers annual income. Factor analysis results indicated that taste, health, freshness and perception influenced consumption of TAVs. These findings imply that consumption of TAVs can be enhanced by educating consumers on the health benefits of TAVs. There is also need to train consumers on preparation and cooking techniques of preserving taste as well as promoting storage technologies which would preserve freshness and nutritional contents of TAVs.
Beyond Greedy Search: Tracking by Multi-Agent Reinforcement Learning-based Beam Search

description: To track the target in a video, current visual trackers usually adopt greedy search for target object localization in each frame, that is, the candidate region with the maximum response score will be selected as the tracking result of each frame. However, we found that this may be not an optimal choice, especially when encountering challenging tracking scenarios such as heavy occlusion and fast motion. To address this issue, we propose to maintain multiple tracking trajectories and apply beam search strategy for visual tracking, so that the trajectory with fewer accumulated errors can be identified. Accordingly, this paper introduces a novel multi-agent reinforcement learning based beam search tracking strategy, termed BeamTracking. It is mainly inspired by the image captioning task, which takes an image as input and generates diverse descriptions using beam search algorithm. Accordingly, we formulate the tracking as a sample selection problem fulfilled by multiple parallel decision-making processes, each of which aims at picking out one sample as their tracking result in each frame. Each maintained trajectory is associated with an agent to perform the decision-making and determine what actions should be taken to update related information. When all the frames are processed, we select the trajectory with the maximum accumulated score as the tracking result. Extensive experiments on seven popular tracking benchmark datasets validated the effectiveness of the proposed algorithm.

description: We investigate the dynamics of particles moving in a spacetime augmented by one extra dimension in the context of the induced matter theory of gravity. We examine the appearance of a fifth force as an effect caused by the extra dimension and discuss two different approaches to the fifth force formalism. We then give two examples of application of both approaches by considering the case of a Ricci-flat warped-product manifold and a generalized Randall-Sundrum space.

Non-equilibrium and non-linear stationary state in thermoelectric materials

description: Efficiency of thermoelectric materials is characterized by the figure of merit Z. Z has been believed to be a peculiar material constant. However, the accurate measurements in the present work reveal that Z has large size dependence and a non-linear temperature distribution appears as stationary state in the thermoelectric material. The observation of these phenomena is achieved by the Harman method. This method is the most appropriate way to investigate the thermoelectric properties because the dc and ac resistances are measured by the same electrode configuration. We describe the anomalous thermoelectric properties observed in mainly (Bi,Sb)2Te3 by the Harman method and then insist that Z is not the peculiar material constant but must be defined as the physical quantity dependent of the size and the position in the material.

description: Despite strong per capita income growth, the structure of sub-Saharan Africa’s economies has not changed markedly in recent decades. In spite of a rapidly growing labour force and urbanizing populations, employment growth in rural areas in general and in non-farm sectors in particular has been slow, and poverty levels in those areas remain relatively higher than in urban areas. So, the key question is: how to catalyse economic transformations that foster inclusive and sustainable development? This is where the role of agriculture is key, given that the overwhelming majority of the population across the continent depends on it as a livelihood source. The case for increasing agricultural productivity to accelerate transformation, investment and industrialization is strongly supported by well-established conceptual frameworks and historical empirical evidence. Though recent gains have been encouraging, agricultural productivity in sub-Saharan Africa still lags behind other regions. The relatively low productivity has led to a loss of competitiveness in agricultural exports and the declining share of the region’s participation in global agricultural trade. Nonetheless, the potential of building on recent gains and developing an agribusiness sector that is responsive to and benefits from the work of smallholder farmers is enormous. This requires the prioritization of two main areas for policy and investment: (i) supporting the emergence of a modern agro‑industrial sector; and (ii) developing the potential of smallholders to engage in high-value activities across agricultural value chains.

description: Ceteris paribus, a 10 per cent increase in on-farm income share increases food consumption per capita by 2.9 per cent, calorie intake per capita per day by 1.7 per cent, and leads to small improvements in dietary diversity. There are significant differences in the relationship between on-farm income shares and caloric shares: a positive and significant relationship with the shares from energy-dense and low-protein cereals and grains, but not significant with shares from nuts/pulses and sugars. Negative relationships are found with shares from roots/tubers, vegetables/fruits, oils/fats and meat/fish/milk. While food consumption and dietary diversity increase with agricultural involvement, the quality of diets is an issue. As purchased calories are associated with richer/high-quality diets, particularly rich in protein, households with lower dependency on agriculture access those diets more easily. This highlights the importance of income diversification to dietary diversity. It also calls for the development and support of nutrition-sensitive agricultural value chains, nutrition education and crop diversification programmes to improve household food and nutrition security.

description: Using the method of the "exact discretization" of the Schrödinger equation, we propose a particular discretized version of the N=2 Supersymmetric Quantum Mechanics. After defining the corresponding shape invariance condition, we show that the energy spectra and wavefunctions for discretized Quantum Mechanical systems can be found using the technique of N=2 Supersymmetric Quantum Mechanics exactly the same way as it is done for their continuous counterparts. As a demonstration of the present method, we find the energy spectrum for a discretized Coulomb potential and its ground state wave function.
