description: US regional economist Richard Florida has developed simple, but very popular ideas to foster regional economic growth: attracting and haltening of members of the so-called 'creative class' by steering the focus of local government development policies for culture, tolerance (towards ethnic and other kinds of minorities) and knowledge. Members of the creative class, characterised by indicators of talent, technology and tolerance, should feel at home in the cities - the result of which would be that creatives either stay in the city where they already lived before or move to those cities which possess the named characteristics. The larger the number of creative people in a city, the better the economic performance of the city. Why that? Because, as Florida postulates, creative people produce economic value added for the region where they live as they more often (than non-creative people) start successful firms and more often engage in high-growth sectors of the economy. Furthermore they are assumed - as an aggregate - to be able to attract existent firms: 'jobs follow (creative) people' instead of 'people follow jobs' to cite an old, but - thanks to Florida - still modern debate among economists. As Florida in his own empirical studies focuses on U. S. metropolitan areas only, there is a need to close the significant research gap in terms of empirical evidence outside the U. S., given the great popularity of his ideas among policy-makers outside the U. S. In the paper five of Florida's main hypotheses are discussed in an explorative approach based upon the available literature. None of these hypotheses receive sufficient support. Consequently, it will hardly be possible to create creative industries by developing related government policies. Comparing government policies in favour of creative industries with government policies of former eras (when, e. g., clusters or high-tech regions belonged to the targets of such policies) there is not much empirical evidence that policy-makers are able or even willing to learn from previous experiences - and failures.

description: OpenStreetMap (OSM) data are widely used but their reliability is still variable. Many contributors to OSM have not been trained in geography or surveying and consequently their contributions, including geometry and attribute data inserts, deletions, and updates, can be inaccurate, incomplete, inconsistent, or vague. There are some mechanisms and applications dedicated to discovering bugs and errors in OSM data. Such systems can remove errors through user-checks and applying predefined rules but they need an extra control process to check the real-world validity of suspected errors and bugs. This paper focuses on finding bugs and errors based on patterns and rules extracted from the tracking data of users. The underlying idea is that certain characteristics of user trajectories are directly linked to the type of feature. Using such rules, some sets of potential bugs and errors can be identified and stored for further investigations. © 2016 Wuhan University. Published by Taylor & Francis Group.

description: We propose a scheme to simulate one-dimensional XXZ-type Heisenberg spin models with competing interactions between nearest-neighbors (NNs) and next-NNs in photon-coupled micro-cavities. Our scheme, for the first time, exploits the rich resources and flexible controls available in such a system to realize arbitrarily adjustable ratios between the effective NN and next-NN coupling strengths. Such powerful capability allows us to simulate frustration phenomena and disorder behaviors in 1-d systems arising from next-NN interactions, a large class of problems of great importance in condensed matter physics. Our scheme is robust due to the lack of atomic excitations which suppresses spontaneous emission and cavity decay strongly.

description: Policy Brief 2 is dedicated to the value chain development of Fonio in Ghana.
Fonio has gained attention in recent years as a nutritious and sustainable crop that could help address food security and nutritional challenges in West Africa and beyond. It offers an alternative to more common cereal grains like sorghum, millet, wheat, rice, and maize and can thrive well on marginal lands. Despite the great benefits associated with the crop it is under exploited and considered an underutilized crop species especially in Africa. A study by the EWA-BELT project funded by EU horizon 2020 has analysed the fonio value chain in Ghana and has made recommendations for the boosting of the value chain in Ghana which are presented in this policy brief. The key messages include;

The factors limiting fonio value chain development include lack of modern farming equipment's, inadequate farming and market information, and less interaction among the chain actors.
Birds attach is one major limiting factor of fonio production.
Processing of fonio is labour intensive
Poor product quality has been observed in fonio VC.
All nodes of the fonio VC are profitable.
The introduction of cost-effective, labour-friendly mechanisation services at the various stages of the value chain, along with access to the credit facility, improved seed, and enhanced knowledge on good agronomic practices, will significantly boost the chain.
It is recommended that marketing and promotion campaigns must be carried out to create awareness of the potential of the fonio value chain. Collective marketing and contract production is recommended as a remedy to the marketing challenges of the fonio value chain at the aggregation and trading nodes. Capacity building at the production and processing nodes is strongly recommended. Increase funding to fonio research is highly recommended for the development of new and improved varieties and new recipes.

description: We report on the detection of individual spin quantum transitions of a single trapped antiproton in a Penning trap. The spin-state determination, which is based on the unambiguous detection of axial frequency shifts in presence of a strong magnetic bottle, reaches a fidelity of 92.1%. Spin-state initialization with >99.9% fidelity and an average initialization time of 24 min are demonstrated. This is a major step towards an antiproton magnetic moment measurement with a relative uncertainty on the part-per-billion level.

description: In this paper we quantify the consistency of word usage in written texts represented by complex networks, where words were taken as nodes, by measuring the degree of preservation of the node neighborhood.} Words were considered highly consistent if the authors used them with the same neighborhood. When ranked according to the consistency of use, the words obeyed a log-normal distribution, in contrast to the Zipf's law that applies to the frequency of use. Consistency correlated positively with the familiarity and frequency of use, and negatively with ambiguity and age of acquisition. An inspection of some highly consistent words confirmed that they are used in very limited semantic contexts. A comparison of consistency indices for 8 authors indicated that these indices may be employed for author recognition. Indeed, as expected authors of novels could be distinguished from those who wrote scientific texts. Our analysis demonstrated the suitability of the consistency indices, which can now be applied in other tasks, such as emotion recognition.

description: The efficiency of wireless technology depends upon the seamless connectivity to the user at anywhere any time.Heterogeneous wireless networks are an integration of different networks with diversified technologies. The most essential requirement for Seamless vertical handover is that the received signal strength should always be healthy. Mobile device enabled with multiple wireless technologies makes it possible to maintain seamless connectivity in highly dynamic environment.Since the available bandwidth is limited and the number of users is growing rapidly, it is a real challenge to maintain the received signal strength in a healthy stage.In this work, the proposed, cost effective parametric estimation for vertical handover shows that the received signal strength maintains a healthy level by considering the novel concept.

description: Based on contactless carrier lifetime measurements performed on p-type boron-doped Czochralski-grown silicon (Cz-Si) wafers, we examine the rate constant Rde of the permanent deactivation process of the boron-oxygen-related defect center as a function of the illumination intensity I at 170°C. While at low illumination intensities, a linear increase of Rde on I is measured, at high illumination intensities, Rde seems to saturate. We are able to explain the saturation by assuming that Rde increases proportionally with the excess carrier concentration Δn and take the fact into account that at sufficiently high illumination intensities, the carrier lifetime decreases with increasing Δn and hence the slope of Δn(I) decreases, leading to an apparent saturation. Importantly, on low-lifetime Cz-Si samples no saturation of the deactivation rate constant is observed for the same illumination intensities, proving that the deactivation is stimulated by the presence of excess electrons and not directly by the photons.

description: Low-frequency high-precision laser interferometry is subject to excess laser-frequency-noise coupling via arm-length differences which is commonly mitigated by locking the frequency to a stable reference system. This approach is crucial to achieve picometer-level sensitivities in the 0.1-mHz to 1-Hz regime, where laser-frequency noise is usually high and couples into the measurement phase via arm-length mismatches in the interferometers. Here we describe the results achieved by frequency stabilizing an external cavity diode laser to a quasimonolithic unequal arm-length Mach-Zehnder interferometer readout at midfringe via balanced detection. We find this stabilization scheme to be an elegant solution combining a minimal number of optical components, no additional laser modulations, and relatively low-frequency-noise levels. The Mach-Zehnder interferometer is designed and constructed to minimize the influence of thermal couplings and to reduce undesired stray light using the optical simulation tool ifocad. We achieve frequency-noise levels below 100 Hz/Hz at 1 Hz and are able to demonstrate the LISA frequency prestabilization requirement of 300 Hz/Hz down to frequencies of 100 mHz by beating the stabilized laser with an iodine-locked reference.

Im Jahr 2013 arbeiteten in Deutschland 24,4% aller abhängig Beschäftigten für einen Stundenlohn unterhalb der Niedriglohnschwelle von 9,30 € pro Stunde. Damit hat sich der Anteil der Niedriglohnbeschäftigten gegenüber 2012 kaum verringert.
Im Durchschnitt erzielten die rund 8,1 Millionen gering bezahlten Beschäftigten einen Stundenlohn von 6,72 € und lagen damit deutlich unter der Niedriglohnschwelle.
Ein besonders hohes Risiko geringer Stundenlöhne hatten im Jahr 2013 Minijobber/innen, unter 25-Jährige, gering Qualifizierte sowie befristet Beschäftigte.
Gleichwohl haben mehr als drei Viertel der Niedriglohnbeschäftigten in Deutschland eine abgeschlossene Berufsausbildung oder einen akademischen Abschluss.
Von Stundenlöhnen unter 8,50 € waren im Jahr 2013 18,9% der abhängig Beschäftigten betroffen. Anders als in einigen anderen Studien angenommen, hat sich dieser Anteil gegenüber 2012 nicht verringert.
Besonders hoch war der Anteil von Beschäftigten mit einem Stundenlohn von weniger als 8,50 € im Gastgewerbe, in der Landwirtschaft und im Handel.

description: We report on ALMA observations of continuum and molecular line emission with 0.4" resolution towards the high-mass star forming region G35.20-0.74 N. Two dense cores are detected in typical hot-core tracers, such as CH3CN, which reveal velocity gradients. In one of these cores, the velocity field can be fitted with an almost edge-on Keplerian disk rotating about a central mass of 18 Msun. This finding is consistent with the results of a recent study of the CO first overtone bandhead emission at 2.3mum towards G35.20-0.74 N. The disk radius and mass are >2500 au and 3 Msun. To reconcile the observed bolometric luminosity (3x10^4 Lsun) with the estimated stellar mass of 18 Msun, we propose that the latter is the total mass of a binary system.

description: We present an analytical proof and numerical demonstrations of the equivalence of the correlation energy from particle-particle random phase approximation (pp-RPA) and ladder-couple-cluster-doubles (ladder-CCD). These two theories reduce to the identical algebraic matrix equation and correlation energy expressions, under the assumption that the pp-RPA equation is stable. The numerical examples illustrate that the correlation energy missed by pp-RPA in comparison with couple-cluster single and double is largely canceled out when considering reaction energies. This theoretical connection will be beneficial to future pp-RPA studies based on the well established couple cluster theory.

description: The eruption of the Hunga submarine volcano on 15 January 2022 was likely the most explosive event of the modern observational era. Its plume reached altitudes over 50km over ground and carried large amounts of water vapor into the typically dry stratosphere. Simulations with the Chemical Lagrangian Model of the Stratospheric (CLaMS) could demonstrate that the behaviour of the injected water vapour could reproduce observations by the Microwave Limb Sounder (MLS) among others for about a month [1]. After one year water vapour in the upper stratosphere is still significantly enhanced compared with the longtime record according to satellite observations by MLS. Here we investigate also the water vapour distribution over this period using a continuation of this CLaMS simulation based on ERA-5 reanalysis data.

description: Policy Brief 1 on Integrated Soil Fertility Management Practices is dedicated to maize.
There is the need for sustainable crop (maize) production in Africa due to growing food demand and the declining soil fertility nexus. This policy brief is aimed at publishing the findings of a research that evaluated the economic and environmental viability of organic fertilizer in maize production. Maize being the most important cereal in sub-Sahara Africa. Three fertilization options (organic, organic + inorganic and inorganic) were tested in east and west Africa to assess their economic and environment feasibility. The major findings include:

Maize yields increases under all three fertilizer options in both the short to long term, however the yields grows faster under full organic fertilizer than the others producing the highest yields in the long term with better soil health contribution.
All fertilizer options are profitable in both short to long term, but organic amendment generates the highest benefits in both short and long term.
Proportional increased in output price and input cost results in increase farm profit similar to the effect of inflation.
The main limiting factor to organic fertilizer use is the unavailability of organic fertilizer
Organic fertilizer and intergrated options are recommended for sustainable maize production in east and west Africa regions. Strategies to increase organic fertilizer production should be pursued by governments.

description: We show that the non-equilibrium time-evolution after interaction quenches in the one dimensional, integrable Hubbard model exhibits a dynamical transition in the half-filled case. This transition ceases to exist upon doping. Our study is based on systematically extended equations of motion. Thus it is controlled for small and moderate times; no relaxation effects are neglected. Remarkable similarities to the quench dynamics in the infinite dimensional Hubbard model are found suggesting dynamical transitions to be a general feature of quenches in such models.

description: Three-dimensional (3D)-bioprinting enables scientists to mimic in vivo micro-environments and to perform in vitro cell experiments under more physiological conditions than is possible with conventional two-dimensional (2D) cell culture. Cell-laden biomaterials (bioinks) are precisely processed to bioengineer tissue three-dimensionally. One primarily used matrix material is sodium alginate. This natural biopolymer provides both fine mechanical properties when gelated and high biocompatibility. Commonly, alginate is 3D bioprinted using extrusion based devices. The gelation reaction is hereby induced by a CaCl2 solution in the building chamber after material extrusion. This established technique has two main disadvantages: (1) CaCl2 can have toxic effects on the cell-laden hydrogels by oxygen diffusion limitation and (2) good printing resolution in the CaCl2 solution is hard to achieve, since the solution needs to be removed afterwards and substituted by cell culture media. Here, we show an innovative approach of alginate bioprinting based on a CaCl2 nebulizer. The device provides CaCl2 mist to the building platform inducing the gelation. The necessary amount of CaCl2 could be decreased as compared to previous gelation strategies and limitation of oxygen transfer during bioprinting can be reduced. The device was manufactured using the MJP-3D printing technique. Subsequently, its digital blueprint (CAD file) can be modified and additive manufactured easily and mounted in various extrusion bioprinters. With our approach, a concept for a more gentle 3D Bioprinting method could be shown. We demonstrated that the concept of an ultrasound-based nebulizer for CaCl2 mist generation can be used for 3D bioprinting and that the mist-induced polymerization of alginate hydrogels of different concentrations is feasible. Furthermore, different cell-laden alginate concentrations could be used: Cell spheroids (mesenchymal stem cells) and single cells (mouse fibroblasts) were successfully 3D printed yielding viable cells and stable hydrogels after 24 h cultivation. We suggest our work to show a different and novel approach on alginate bioprinting, which could be useful in generating cell-laden hydrogel constructs for e.g., drug screening or (soft) tissue engineering applications.

description: Continuous chromatography can surmount the disadvantages of batch chromatography like low productivities and extensive usage of consumables. In this work, a 4-column continuous chromatographic system based on the principle of periodic counter-current chromatography (PCCC) was developed and tested with a model protein mixture of BSA and lysozyme. The PCCC system was specially designed for membrane adsorbers as an alternative to conventional columns to facilitate the use of disposable process units and to further increase the productivity due to higher convective mass transport in the membrane adsorber. Membrane adsorber Sartobind® Q was used to continuously purify BSA from the protein mixture. The usage of PCCC led to an increased capacity utilization (here 20%) and higher space–time-yields, and thus to a remarkable productivity increase and cost savings.

description: We study classical, real Klein-Gordon theory on Lorentzian Anti de Sitter (AdS_{1,d}) spacetimes with spatial dimension d. We give a complete list of well defined and bounded Klein-Gordon solutions for three types of regions on AdS: slice (time interval times all of space), rod hypercylinder (all of time times solid ball in space), and tube hypercylinder (all of time times solid shell in space). Hypercylinder regions are of natural interest for AdS since the neighborhood of the AdS-boundary is a tube. For the solution spaces of our regions we find the actions induced by the AdS isometry group SO(2,d). For all three regions we find one-to-one correspondences between initial data and solutions on the regions. For rod and tube regions this initial data can also be given on the AdS boundary. We calculate symplectic structures associated to the solution spaces, and show their invariance under the isometry actions. We compare our results to the corresponding expressions for (3+1)-dimensional Minkowski spacetime, arising from AdS_{1,3} in the limit of large curvature radius.

description: In agricultural ecosystems, insect pests, pathogens, weather patterns, and reduced soil fertility pose major challenges to crop productivity and are responsible for significant yield losses worldwide. Iris yellow spot virus (IYSV) vectored by Thrips tabaci Lindeman, is a major hindrance to onion production in eastern Africa. Control measures often rely on insecticides with deleterious effects. Endophytes are one key alternative as they can play important roles in mediating induced systemic resistance. Hence, we examined the potential effect of endophytic fungus Hypocrea lixii (F3ST1) on feeding and replication of IYSV on endophyte-colonized (E+) and endophyte-free (E-) onion plants. For more precise assessment, replication was also tested using leaf disk bioassays and individual thrips. The number of feeding punctures was significantly lower in E+ as compared to E- plants. Disease level was significantly lower in E+ as compared to E- plants for four weeks post-exposure to thrips. IYSV replication was reduced by 2.5-fold in endophytic treatment on both whole plant and leaf disk assays. Thrips tabaci showed 2 times higher feeding activities on endophyte-free onion leaf disks as compared to the endophyte-inoculated leaf disks. Our results suggest potential utility of the endophytes to reduce feeding damage and virus infection on onion plants. Further studies should be conducted to elucidate the secondary metabolites involved in such endophyte-thripsvirus mediated interaction and determine whether the interactions extend for this and other onion varieties and viruses under field conditions.
Critical velocity, vortex shedding and drag in a unitary Fermi superfluid

description: We study the real-time motion of a microscopic object in a cold Fermi gas at unitary conditions by using an extended Thomas-Fermi density functional approach. We find that spontaneous creation of singly quantized vortex-antivortex pairs occurs as a critical velocity is exceeded, which leads to a drag between the moving object and the Fermi gas. The resulting force is linear in the velocity for subsonic motion and becomes quadratic for supersonic motion.

description: This article throws light on a slightly unusual example of a trans-cultural artefact, namely a dhāraṇī-amulet, which in this case features the imprint and creative designs of both Tibetan and Chinese Buddhist cultures, even though its basic iconic components remain rooted in Indian Buddhism. Although not unique among the Dunhuang material, it is a fascinating and slightly curious example of how Buddhism served as a common denominator for Buddhist practitioners of both cultures during the period of the Tibetan rule of Shazhou (沙州), i.e. roughly between the late 750s/early 760s and 848. The example discussed here is from the collection of the British Museum, and has for unknown reasons hitherto escaped the notice of the scholarly community.

Evolving Communities with Individual Preferences

Subjects: subject: Probability (math.PR)

description: The goal of this paper is to provide mathematically rigorous tools for modelling the evolution of a community of interacting individuals. We model the population by a measure space where the measure determines the abundance of individual preferences. The preferences of an individual are described by a measurable choice of a rough path. We focus on the case of weakly interacting systems, where we are able to exhibit the existence and uniqueness of consistent solutions. In general, solutions are continuum of interacting threads analogous to the huge number of individual atomic trajectories that together make up the motion of a fluid. The evolution of the population need not be governed by any over-arching PDE. Although one can match the standard nonlinear parabolic PDEs of McKean-Vlasov type with specific examples of communities in this case. The bulk behaviour of the evolving population provides a solution to the PDE. An important technical result is continuity of the behaviour of the system with respect to changes in the measure assigning weight to individuals. Replacing the deterministic measure with the empirical distribution of an i.i.d. sample from it leads to many standard models, and applying the continuity result allows easy proofs for propagation of chaos. The rigorous underpinning presented here leads to uncomplicated models which have wide applicability in both the physical and social sciences. We make no presumption that the macroscopic dynamics are modelled by a PDE. This work builds on the fine probability literature considering the limit behaviour for systems where a large no of particles are interacting with independent preferences; there is also work on continuum models with preferences described by a semi-martingale measure. We mention some of the key papers.

description: Plants continually adjust the photosynthetic functions in their leaves to fluctuating light, thereby optimizing the use of photosynthetic nitrogen (Nph) at the canopy level. To investigate the complex interplay between external signals during the acclimation processes, a mechanistic model based on the concept of protein turnover (synthesis and degradation) was proposed and parameterized using cucumber grown under nine combinations of nitrogen and light in growth chambers. Integrating this dynamic model into a multi-layer canopy model provided accurate predictions of photosynthetic acclimation of greenhouse cucumber canopies grown under high and low nitrogen supply in combination with day-to-day fluctuations in light at two different levels. This allowed us to quantify the degree of optimality in canopy nitrogen use for maximizing canopy carbon assimilation, which was influenced by Nph distribution along canopy depth or Nph partitioning between functional pools. Our analyses suggest that Nph distribution is close to optimum and Nph reallocation is more important under low nitrogen. Nph partitioning is only optimal under a light level similar to the average light intensity during acclimation, meaning that day-to-day light fluctuations inevitably result in suboptimal Nph partitioning. Our results provide insights into photoacclimation and can be applied to crop model improvement.

description: Bei der aktuellen Kontroverse darüber, ob sprachliche Geschlechtergerechtigkeit nötig oder möglich ist und wie man sie ggf. realisiert, ist man immer auf den gegenwärtigen Sprachzustand fixiert, der als absolut unveränderlich postuliert wird. Interessanterweise beschwören viele (allen voran der Verein Deutsche Sprache (VDS)), die sich gegen geschlechtergerechtes Formulieren wenden, die Sprachgeschichte – in der irrigen Annahme, dass das, wofür die plädieren, es schon immer gegeben habe, dass Sprache somit stabil und unveränderlich sei, ja, dass man ihr sogar Gewalt antue, würde man sie an neue Erfordernisse anpassen. Dabei ist Sprachwandel nichts anderes als die ständige Anpassung an gesellschaftliche Neuerungen.
