description: The present study examines profitability, technical, cost and allocative efficiencies of cassava production by applying Data Envelopment Analysis (DEA) of 315 farmers from three regions of Delta State, Nigeria. Results revealed that cassava production was profitable (overall profit margin 1.93), with significant differences across regions as well as farm size categories. Mean levels of technical, cost and allocative efficiencies are low estimated at 40%, 29% and 73% respectively, also with significant differences across regions as well as farm size categories. The implication is that cassava production can be increased substantially by reallocation of resources to optimal levels, given input and output prices. The results also confirmed inverse size-productivity and size-efficiency relationships in cassava production, i.e., the marginal farms are the most productive, profitable, and efficient. Subsistence pressure significantly reduces technical and cost efficiency. Extension contact significantly improves allocative efficiency whereas it reduces technical and cost efficiency. There is no gender difference in performance implying both men and women performs equally well. Farmers located in Delta South and Delta North are technically efficient relative to Delta Central. However, farmers located in Delta North are allocatively inefficient. Investment in extension services to make it more effective and improvements in infrastructure are suggested as policy options.

description: This paper develops a multifidelity method that enables estimation of failure probabilities for expensive-to-evaluate models via information fusion and importance sampling. The presented general fusion method combines multiple probability estimators with the goal of variance reduction. We use low-fidelity models to derive biasing densities for importance sampling and then fuse the importance sampling estimators such that the fused multifidelity estimator is unbiased and has mean-squared error lower than or equal to that of any of the importance sampling estimators alone. By fusing all available estimators, the method circumvents the challenging problem of selecting the best biasing density and using only that density for sampling. A rigorous analysis shows that the fused estimator is optimal in the sense that it has minimal variance amongst all possible combinations of the estimators. The asymptotic behavior of the proposed method is demonstrated on a convection-diffusion-reaction partial differential equation model for which $10^5$ samples can be afforded. To illustrate the proposed method at scale, we consider a model of a free plane jet and quantify how uncertainties at the flow inlet propagate to a quantity of interest related to turbulent mixing. Compared to an importance sampling estimator that uses the high-fidelity model alone, our multifidelity estimator reduces the required CPU time by 65\% while achieving a similar coefficient of variation.

description: The labour employment trends of 2003 Swiss FADN farms between 2004 and 2009 are studied, differentiating between the use of on- and off-farm family labour, employees, and contracting services accomplished by and for third parties. By means of a correlation and data envelopment analysis, the relationships between changes in labour input, farm size, productivity and income are empirically explored. With the aid of a cluster analysis 7 major strategies to adjust labour input are revealed whereas slightly over half of the farms in the period under consideration leave labour input at a constant level. Although some of the clusters differ substantially in terms of growth in both labour productivity and income, differences in total factor productivity are not significant.

description: Broad-band measurements of flux for galaxies at different redshifts measure different regions of the rest-frame galaxy spectrum. Certain astronomical questions, such as the evolution of the luminosity function of galaxies, require transforming these magnitudes into redshift-independent quantities. To prepare to address these astronomical questions, investigated in detail in subsequent papers, we fit spectral energy distributions (SEDs) to broad band photometric observations, in the context of the optical observations of the Sloan Digital Sky Survey (SDSS). Linear combinations of four spectral templates can reproduce the five SDSS magnitudes of all galaxies to the precision of the photometry. Expressed in the appropriate coordinate system, the locus of the coefficients multiplying the templates is planar, and in fact nearly linear. The resulting reconstructed SEDs can be used to recover fixed frame magnitudes over a range of redshifts. This process yields consistent results, in the sense that within each sample the intrinsic colors of similar type galaxies are nearly constant with redshift. We compare our results to simpler interpolation methods and galaxy spectrophotometry from the SDSS. The software that generates these results is publicly available and easily adapted to handle a wide range of galaxy observations.

description: The introduction of the Water Framework Directive in 2000 (European Parliament and Council 2000) has incentivised policy-makers to bring the quality of all water streams in EU member states up to a ‘good ecological status’ by 2015. Although a lot of work has been carried out since the introduction of the Directive, it is also evident that progress in improving water quality has been very slow. The main reason for such slow progress is the lack of robust evidence about the sources of pollution and the effects of possible mitigation measures. Also, there is insufficient knowledge regarding the economic implications of the various mitigation options. In this paper we introduce a microsimulation model that can help policymakers to evaluate the economic impact of Nitrogen (N) mitigation measures. In this initial case study, two measures are considered: 1) a stocking rate reduction to achieve a maximum level of organic nitrogen of 170 kg/ha; 2) a 20 percent stocking rate reduction. The results of this study confirm the hypothesis that introduction of these measures would lead to reduction in farm gross margins, which is consistent with the previous research in Ireland and UK.

description: Subgenus Halolimnesia subgen. nov.
 Diagnosis. Sixth segment of I- and II-L modified in male, distally tapering, and with multiple irregular constrictions at the ventral margin. Ac relatively small, Ac-2 smaller than Ac-1 and Ac-3, the distance between Ac-1 and Ac-2 much larger than between Ac-2 and Ac-3; genital plates in male separate; numbers of genital setae low (5-6 in male, 3 in female). Ventral seta of P-2 heavy, peg-shaped, inserted slightly laterally.
 Type species. Limnesia diversipes sp. nov.
 Etymology. The new subgenus is named for its occurrence in saline environment.
 Remarks. The slightly modified first and especially the second leg, with the sixth segment distally tapering and with multiple irregular constrictions at the ventral margin is very distinctive and will separate members of the subgenus from representatives of all other other subgenera of this genus. Sexual dimorphism in I-L has not been reported in other limnesiids and a modified second leg is found only in Xenolimnesia Smit from Cameroon (Smit 1994), a genus having the three distal segments highly modified.

description: In Germany, stakeholders favour a few strategies to foster open access transformation: Library consortia negotiate (national) licensing models with major publishers; infrastructural service providers focus on flipping journals and therefore cater to the needs of renowned publishing projects. At the same time, for public research funding academic reputation (still) seems a key criterion. In doing so, major advantages of electronic publishing and bibliodiversity are given away, which include supporting innovative publication projects (inter-/transdisciplinary contexts, non-profit models, publications focusing on emerging topics, peripheral-local publication initiatives, small-subject-based initiatives) and developing new publication formats, tools and workflows (community-based and cooperative). The project “Innovative Open Access in Small Sciences (InnOAccess)” (June 2019 - February 2021; funded by the DFG) responds to these challenges by analysing the market of scholar-led, non-APC journals in Germany, developing reusable technical workflows for smaller publishing projects and testing new, interlocking financing models. One section of the poster features the results of a survey (sample size = 101) on the state of scholar-led, non-APC journals in Germany: How are they governed, staffed and funded? What are the budgetary options? Here it became clear, for example, that one-size-fits-all solutions do not work, mainly because publication cultures are as different as their publishing institutions. Particularly publishing projects beyond university infrastructures seem to have found creative financing opportunities and technical solutions from which the field of scholar-led-publishing as a whole can profit. The poster furthermore outlines, based on the findings of the survey and a systematic evaluation of existing business models, how technical workflows and a modular approach to journal financing contributes to sustainable publishing. This includes a streamlined journal workflow based on open source applications, emphasising cooperative practices and using community-based know-how. Addressing the precarious funding situation of scholar-led, non-APC journals, the poster introduces a set of financing opportunities that have been tested and are deemed manageable with regard to the needs and administrative capacities of this journal segment. In total, the poster sheds light on the precarious situation of scholar-led journals in Germany, emphasizes their importance for the open access ecosystem and offers insights on how to improve their situation in a practical fashion.

description: The proximity effect in hybrid superconducting - normal metal structures is shown to affect strongly the coherent oscillations of the superconducting order parameter $Δ$ known as the Higgs modes. The standard Higgs mode at the frequency $2Δ$ is damped exponentially by the quasiparticle leakage from the primary superconductor. Two new Higgs modes with the frequencies depending on both the primary and induced gaps in the hybrid structure are shown to appear due to the coherent electron transfer between the superconductor and the normal metal. Altogether these three modes determine the long-time asymptotic behavior of the superconducting order parameter disturbed either by the electromagnetic pulse or the quench of the system parameters and, thus, are of crucial importance for the dynamical properties and restrictions on the operating frequencies for superconducting devices based on the proximity effect used, e.g., in quantum computing, in particular, with topological low-energy excitations.

description: While comprehensive farm level models for the dairy, beef and cereal sectors have previously been developed, to date, relatively little research has been conducted on the economics of the sheep sector at farm level. Nationally representative farm level data from Teagasc’s National Farm Survey (NFS) is used to develop a model examining the economic factors of concentrate usage on Irish sheep farms informed by the current body of literature on pastoral based production systems research. Results from a 2 step random effects panel regression of a demand function for concentrate use with log linear functional form support the established production literature. The demand for concentrates on Irish sheep farms was found to be elastic and thus sensitive to price changes. Farm labour input, fertiliser application, subscription to an extension and research provider and date of lambing were found to be significantly associated with concentrate demand on sheep enterprises. Results from a second model specification indicate the presence of spatially heterogeneous effects of lambing on concentrate demand across regions.

description: Long-term variations are well-known in Be X-ray binaries, and are attributed to non-orbital changes in the structure of the Be circumstellar (equatorial) disc. However, the timescales involved are so long (tens of days, to years) that systematic studies have been very restricted. The ~8 year MACHO monitoring of the Large Magellanic Cloud (LMC) therefore presents an ideal opportunity to undertake such studies of Be X-ray systems that lie within the monitored fields. Here we present MACHO observations of two LMC Be X-ray transients, EXO 0531-66 and H 0544-665, the light curves of which show substantial (~0.5 mag) long-term variations. However, our analysis shows little evidence for any periodic phenomena in the light curves of either source. We find an upper limit for detection of a short (1-100 d) periodicity in the V- and R-band light curves of EXO 0531-66 of 0.041 mag and 0.047 mag semi-amplitude, respectively. The upper limits for the V- and R-band data of H 0544-665 are 0.054 mag and 0.075 mag semi-amplitude, respectively. Both EXO 0531-66 and H 0544-665 become redder as they brighten, possibly due to variations in the structure of the equatorial disc around the Be star. Spectra of both sources show H$α$ emission; for EXO 0531-66 we find the emission varies over time, thereby confirming its optical identification.

description: Tactical decision making for autonomous driving is challenging due to the diversity of environments, the uncertainty in the sensor information, and the complex interaction with other road users. This paper introduces a general framework for tactical decision making, which combines the concepts of planning and learning, in the form of Monte Carlo tree search and deep reinforcement learning. The method is based on the AlphaGo Zero algorithm, which is extended to a domain with a continuous state space where self-play cannot be used. The framework is applied to two different highway driving cases in a simulated environment and it is shown to perform better than a commonly used baseline method. The strength of combining planning and learning is also illustrated by a comparison to using the Monte Carlo tree search or the neural network policy separately.

description: When a carbon nanotube is truncated with a certain type of edges, boundary states localized near the edges appear at the fermi level. Starting from lattice models, low energy effective theories are constructed which describe electron correlation effects on the boundary states. We then focus on a thin metallic carbon nanotube which supports one or two boundary states, and discuss physical consequences of the interaction between the boundary states and bulk collective excitations. By the renormalization group analyses together with the open boundary bosonization, we show that the repulsive bulk interactions suppress the charge fluctuations at boundaries, and assist the spin polarization.

description: A new method, bypass-current plasma-MIG hybrid arc welding, was proposed to weld AA 5083 aluminium alloy. A comparative investigation between simulation and experiment was performed to quantify different effects of bypass-current and out plasma current on droplet transfer behaviours. The results show that when the bypass-current is 15 A, the droplets present a projected transfer mode, and its period is 22 ms. But if the outer plasma current is 15 A, the transfer frequency increases 19.1 Hz, and the sizes of the droplet show a slight increase. This is due to the reduction of electromagnetic force and arc plasma force on droplets. The research outcomes provide benefits to the droplet transfer behaviours in control and optimisation during aluminium alloy welding.

description: Droughts are predicted to increase in frequency and intensity for large parts of Africa. It is unclear how this may impact native grazers in protected areas, and how these outcomes may differ under contrasting management approaches. Reducing artificial water sources and increasing the size of protected areas have been proposed as management responses that could possibly increase system resilience and buffer herbivores against large-scale mortality during droughts. Long-term spatially explicit buffalo, elephant and hippo census data from the Kruger National Park and adjacent private protected areas during three droughts (1982/1983, 1991/1992 and 2015/2016) provided a unique opportunity to explore how a range of management actions influenced megaherbivore responses across six regions. Drought responses varied significantly at a regional scale for all three megaherbivores, supporting the notion that size, and the associated emergent property of spatio-temporal heterogeneity, provides a buffer during droughts. Furthermore, regional buffalo population declines (as a function of mortality, movement and birth rates) were highest in areas with high waterhole density and concomitant low levels of herbaceous biomass, compared with areas that experienced similar rainfall, but had lower waterhole density and higher herbaceous biomass. Elephant mortalities were negligible, but elephants displayed regional movement patterns, seemingly attracted to higher water provision densities during the drought. Our results highlight that drought interacts with spatio-temporal environmental gradients and management actions and illustrates how the Greater Kruger National Park is increasingly functioning as an integrated ecosystem for megaherbivores.

description: Neutrinos generated during solar flares remain elusive. However, after $50$ years of discussion and search, the potential knowledge unleashed by their discovery keeps the search crucial. Neutrinos associated with solar flares provide information on otherwise poorly known particle acceleration mechanisms during solar flare. For neutrino detectors, the separation between atmospheric neutrinos and solar flare neutrinos is technically encumbered by an energy band overlap. To improve differentiation from background neutrinos, we developed a method to determine the temporal search window for neutrino production during solar flares. Our method is based on data recorded by solar satellites, such as Geostationary Operational Environmental Satellite (GOES), Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI), and GEOTAIL. In this study, we selected 23 solar flares above the X5.0 class that occurred between 1996 and 2018. We analyzed the light curves of soft X-rays, hard X-rays, $γ$-rays, line $γ$-rays from neutron capture as well as the derivative of soft X-rays. The average search windows are determined as follows: $4,178$ s for soft X-ray, $700$ s for derivative of soft X-ray, $944$ s for hard X-ray ($100$-$800$ keV), $1,586$ s for line $γ$-ray from neutron captures, and $776$ s for hard X-ray (above $50$ keV). This method allows neutrino detectors to improve their sensitivity to solar flare neutrinos.

description: The Country Research Agenda for Jordan was developed over the span of nine months as part of the first year of the Education Research in Conflict and Protracted Crisis (ERICC) program. ERICC is a large-scale FCDO-funded, three-year program to generate new, rigorous research evidence on the most effective approaches to providing education in conflict and protracted crisis contexts. Ultimately, the program aims to expand the global research base in this area and provide relevant evidence to policy-makers and other education stakeholders to support necessary reform in education delivery in conflict- and crisis-affected contexts. To this end, ERICC is being implemented in six conflict-affected countries – Jordan, Bangladesh (Cox’s Bazar), and Nigeria in the first cohort and South Sudan, Lebanon and Syria in the second cohort. The research agenda presented here highlights ERICC’s co-constructed national research priorities within Jordan, the rationale and factors that inform these priorities, and research plans to enact the agenda moving forward.

description: In this work, we study the near-field heat transfer between composite nanostructures. It is demonstrated that thermally excited surface plasmon polaritons, surface phonon polaritons, and hyperbolic phonon polaritons in such composite nanostructures significantly enhance the near-field heat transfer. To further analyze the underlying mechanisms, we calculate energy transmission coefficients and obtain the near-field dispersion relations. The dispersion relations of composite nanostructures are substantially different from those of isolated graphene, silicon carbide (SiC) films, and SiC nanowire arrays due to the strong coupling effects among surface polaritonic modes. We identify four pairs of strongly coupled polaritonic modes with considerable Rabi frequencies in graphene/SiC film composite structures that greatly broaden the spectral peak. We confirm that near-field strong coupling effects between surface plasmon polaritons and hyperbolic phonon polaritons in the in-plane Reststrahlen band are different from those in the out-of-plane Reststrahlen band due to the different types of hyperbolicity. In addition, we analyze the effective tunability of the near-field heat transfer of graphene/SiC nanowire arrays composite structures by adjusting the chemical potential of graphene, the height and volume filling factor of the SiC nanowire arrays. This work provides a method to manipulate the near-field heat transfer with the use of strongly coupled surface polaritonic modes.

description: Droughts are expected to become more frequent and severe, due to climate change, with uncertain consequences for savanna vegetation. Drought-driven tree mortality has been observed in some savannas, but little is known about how tolerant savanna trees are to drought, or what determines differences among species in drought vulnerability. Here, we examine which characteristics best distinguished tree species that were most negatively affected by a recent drought in Kruger National Park, South Africa. Woody-encroaching, root-suckering species, which tended to have relatively low investments in non-structural carbohydrates, had the highest mortality rates. Of particular interest was Dichrostachys cinerea, a notable contributor to widespread woody encroachment across southern African savannas, which suffered high drought mortality. Using rainfall maps and vegetation survey data, we show that D. cinerea distributions in Kruger National Park are limited to areas with higher mean annual rainfall and lower past drought frequency, and stem densities are lower where droughts have occurred more frequently, suggesting that past droughts have had lasting impacts on the distribution and abundance of this species. Woody encroachers, such as D. cinerea, may face a trade off between traits promoting proliferation vs. drought tolerance, and more frequent and severe droughts could increasingly limit their spread.

description: The poster presents a holistic concept for open science education and in particular data literacy as well as research data management [RDM] developed by the project bw2FDM in BadenWürttemberg. Faced with a multitude of courses, webinars and other training opportunities dedicated to these topics, just adding more is not an efficient approach. Rather cooperation and coordination are essential. Therefore, original content is combined with networking efforts on a state as well as federal level in order to achieve synergies. Nevertheless, the creation of a multifaceted set of training opportunities is a core part of our project. This meshes different didactic formats. A main component is an asynchronous online course “Open Science: Von Daten zu Publikationen” [1] that covers different aspects of RDM from a practical, technical and legal view. This course has even become part of the regular curriculum at the University of Constance. It is complemented by training sessions and webinars that delve deeper into specific issues. Furthermore, bw2FDM is responsible for the information platform forschungsdaten.info, which offers a comprehensive collection of articles covering a wide variety of RDM matters. None of these services is limited to a specific institution, rather they are aimed at the entire German-speaking community. However, bw2FDM strives to avoid insular solutions as well as duplicating the efforts of other RDMexperts. In consequence, we initiated a working group dedicated to RDM-training in BadenWürttemberg. This is not just a forum for exchange but also a nucleus for cooperative solutions to data literacy education. The same approach has been applied to foschungsdaten.info: partnerships with 18 other institutions made it possible to assemble a diverse and highly specialized editorial staff that consistently provides new content and improves the platform. Recently, a new series of webinars under the label forschungsdaten.info live has been launched that has these experts join efforts in order to tailor training session for specific scientific communities. For example, the first webinar focused on geosciences. Last but not least, a special focus lies on sustainability. For that reason, all educational resources as well as the content of forschungsdaten.info are published under open licenses such as CC BY 4.0 or under a copyright waiver like CC0 1.0. This ensures their reusability and enables other institutions to adept the materials for their own purposes without legal limitations. Moreover, we are optimistic that our cooperative approach to RDM education will increase the long-term effectiveness of our efforts and might even serve as a blueprint for other institutions.

description: In recent years, the growth in local food marketing channels has been significant. Most of the research in this field examining the economic implication of these trends has focused post-farmgate including supply chain analysis (e.g. Hardesty et al., 2014; King et al., 2010), regional economic impacts (e.g. Brown et al., 2014; Hughes et al., 2008; Jablonski et al., 2016), and consumer values and motivations that have driven demand (e.g. Costanigro, 2014; Lusk and Briggeman, 2009). To date, with the exception of a few case studies examining expenses and sales by channel assessment (LeRoux et al., 2010; Hardesty and Leff, 2010; Jablonski and Schmit 2016) there has been little research that examines the impact on financial viability among farms selling through these markets. The goal of this paper is twofold: first, to identify the factors that have the greatest influence on the efficiency of farmers and ranchers that participate in local food systems, and second, to estimate the relationship between marketing strategy and farm financial efficiency, with a particular focus on variations across farm size. Our estimation of the stochastic production frontier suggests that scale, production enterprise specialty, market outlet choices, land ownership, and management of expenses have the greatest influence on producer financial efficiency. Our model suggests that scale has the largest impact on financial efficiency, providing evidence that, all else constant, the most important factor in the efficiency of direct market producers is scale. When profit is defined as operating profit, results indicate that marketing channel is not an important indicator of efficiency. But when profit is defined as return on assets, marketing channel is an important indicator of efficiency, albeit less than is scale. Results from this analysis indicate there are economies of scale associated with farms and ranches that sell through local and regional markets, and that scale rather than marketing channel has the largest influence on efficiency.

description: Some present day results for few-nucleon bound state, two-nucleon correlation functions and scattering observables are briefly reviewed. The old idea of the Coulomb sum rule as a way to extract the pp correlation function is reconsidered. It appears to be an ideal case to probe properties of the density operator and the ground state wave functions without disturbances of final state interactions (FSI) in exclusive electron scattering on 3He. Also exclusive photodisintegration of 3He is regarded which appears to be promising to identify 3N force effects.

description: WTe2, as a type-II Weyl semimetal, has 2D Fermi arcs on the (001) surface in the bulk and 1D helical edge states in its monolayer. These features have recently attracted wide attention in condensed matter physics. However, in the intermediate regime between the bulk and monolayer, the edge states have not been resolved owing to its closed band gap which makes the bulk states dominant. Here, we report the signatures of the edge superconductivity by superconducting quantum interference measurements in multilayer WTe2 Josephson junctions and we directly map the localized supercurrent. In thick WTe2 (~60 nm), the supercurrent is uniformly distributed by bulk states with symmetric Josephson effect ($\left|I_c^+(B)\right|=\left|I_c^-(B)\right|$). In thin WTe2 (10 nm), however, the supercurrent becomes confined to the edge and its width reaches up to 1.4 um and exhibits non-symmetric behavior $\left|I_c^+(B)\right|\neq \left|I_c^-(B)\right|$. The ability to tune the edge domination by changing thickness and the edge superconductivity establishes WTe2 as a promising topological system with exotic quantum phases and a rich physics.

description: This study provides a micro perspective on the impact that mobile money services have on an individual’s saving behavior using 2013 Uganda FinScope data. The results show that although saving through mobile phones is not a common practice in Uganda, being a registered mobile money user increases the likelihood of saving with mobile money. Using mobile money to save is more prevalent in urban areas and in the central region than in other regions. This can be explained by several factors. First, rural dwellers on average tend to have lower incomes and thus have a lower propensity to save compared with their urban counterparts. Second, poor infrastructure in rural areas in terms of the lack of electricity and poor telecommunication network coverage may limit the use of mobile phones and consequently the use of mobile money as a saving mechanism. Overall, the use of mobile money as a saving mechanism is still very low, which could be partly explained by legal limitations that do not incorporate mobile finance services into mobile money. The absence of interest payments on mobile money savings may also act as a disincentive to save through this mechanism. Given the emerging mobile banking services, there is need to create greater awareness and to enhance synergies between telecoms companies and commercial banks.
