description: Recent outbreaks of African swine fever virus (ASFV) have seen the movement of this virus into multiple new regions with devastating impact. Many of these outbreaks are occurring in remote, or resource-limited areas, that do not have access to molecular laboratories. Loop-mediated isothermal amplification (LAMP) is a rapid point of care test that can overcome a range of inhibitors. We outline further development of a real-time ASFV LAMP, including field verification during an outbreak in Timor-Leste. To increase field applicability, the extraction step was removed and an internal amplification control (IAC) was implemented. Assay performance was assessed in six different sample matrices and verified for a range of clinical samples. A LAMP detection limit of 400 copies/rxn was determined based on synthetic positive control spikes. A colourmetric LAMP assay was also assessed on serum samples. Comparison of the LAMP assay to a quantitative polymerase chain reaction (qPCR) was performed on clinical ASFV samples, using both serum and oral/rectal swabs, with a substantial level of agreement observed. The further verification of the ASFV LAMP assay, removal of extraction step, implementation of an IAC and the assessment of a range of sample matrix, further support the use of this assay for rapid in-field detection of ASFV.

description: In this paper, we investigate the properties of frustrated three-leg spin tubes under a magnetic field. We concentrate on two kind of geometries for these tubes, one of which is relevant for the compound $\mathrm{[(CuCl_2tachH)_3Cl]Cl_2}$. We combine an analytical path integral approach with a strong coupling approach, as well as large-scale Density Matrix Renormalization Groups (DMRG) simulations, to identify the presence of plateaux in the magnetization curve as a function of the value of spin $S$. We also investigate the issue of gapless non-magnetic excitations on some plateaux, dubbed chirality degrees of freedom for both tubes.

description: There is ample observational evidence that the star formation rate (SFR) surface density, Sigma_SFR, is closely correlated with the surface density of molecular hydrogen, Sigma_H2. This empirical relation holds both for galaxy-wide averages and for individual >=kpc sized patches of the interstellar medium (ISM), but appears to degrade substantially at a sub-kpc scale. Identifying the physical mechanisms that determine the scale-dependent properties of the observed Sigma_H2-Sigma_SFR relation remains a challenge from a theoretical perspective. To address this question, we analyze the slope and scatter of the Sigma_H2-Sigma_SFR relation using a set of cosmological, galaxy formation simulations with a peak resolution of ~100 pc. These simulations include a chemical network for molecular hydrogen, a model for the CO emission, and a simple, stochastic prescription for star formation that operates on ~100 pc scales. Specifically, star formation is modeled as a Poisson process in which the average SFR is directly proportional to the present mass of H2. The predictions of our numerical model are in good agreement with the observed Kennicutt-Schmidt and Sigma_H2-Sigma_SFR relations. We show that observations based on CO emission are ill suited to reliably measure the slope of the latter relation at low (<20 M_sun pc^-2) H2 surface densities on sub-kpc scales. Our models also predict that the inferred Sigma_H2-Sigma_SFR relation steepens at high H2 surface densities as a result of the surface density dependence of the CO/H2 conversion factor. Finally, we show that on sub-kpc scales most of the scatter in the relation is a consequence of discreteness effects in the star formation process. In contrast, variations of the CO/H2 conversion factor are responsible for most of the scatter measured on super-kpc scales.

description: We used UKIRT near infrared (NIR) broad band JHK photometry, narrow band imaging of the 1-0S(1) molecular hydrogen emission line and mid infrared Spitzer IRAC data to investigate the nature of the young cluster Mercer14. Foreground star counts in decontaminated NIR photometry and a comparison with the Besancon Galaxy Model are performed to estimate the cluster distance. This method yields a distance of 2.5kpc with an uncertainty of about 10% and can be applied to other young and embedded clusters. Mercer14 shows clear signs of ongoing star formation with several detected molecular hydrogen outflows, a high fraction of infrared excess sources and an association to a small gas and dust cloud. Hence, the cluster is less than 4Myrs old and has a line of sight extinction of A_K=0.8mag. Based on the most massive cluster members we find that Mercer14 is an intermediate mass cluster with about 500Mo.

description: We present results of the prompt, early, and afterglow optical observations of five gamma-ray bursts, GRBs 100901A, 100902A, 100905A, 100906A, and 101020A, made with the Mobile Astronomical System of TElescope-Robots in Russia (MASTER-II net), the 1.5-m telescope of Sierra-Nevada Observatory, and the 2.56-m Nordic Optical Telescope. For two sources, GRB 100901A and GRB 100906A, we detected optical counterparts and obtained light curves starting before cessation of gamma-ray emission, at 113 s and 48 s after the trigger, respectively. Observations of GRB 100906A were conducted with two polarizing filters. Observations of the other three bursts gave the upper limits on the optical flux; their properties are briefly discussed. More detailed analysis of GRB 100901A and GRB 100906A supplemented by Swift data provides the following results and indicates different origins of the prompt optical radiation in the two bursts. The light curves patterns and spectral distributions suggest a common production site of the prompt optical and high-energy emission in GRB 100901A. Results of spectral fits for GRB 100901A in the range from the optical to X-rays favor power-law energy distributions with similar values of the optical extinction in the host galaxy. GRB 100906A produced a smoothly peaking optical light curve suggesting that the prompt optical radiation in this GRB originated in a front shock. This is supported by a spectral analysis. We have found that the Amati and Ghirlanda relations are satisfied for GRB 100906A. An upper limit on the value of the optical extinction on the host of GRB 100906A is obtained.

description: The search for planets orbiting stars other than the Sun has led to the discovery of over one thousand new worlds. The majority of these planets have been very large, Jupiter sized planets located very close to their host star. Transit surveys such as Kepler and SuperWASP monitor thousands of stars looking for periodic dips in light caused by a planet passing between our view point on Earth and their host star, blocking a fraction of the emitted star light. One of the primary limitations in detecting a small, Earth sized planet comes from stellar activity induced signals within the data collected by exoplanet missions. These signals can, however, be used to our advantage. In this thesis, asymmetries in transit light curves are exploited to reveal properties of both the planet and the host stars themselves. An asymmetry in the near-ultraviolet transit light curve of WASP-12b, one of the largest and hottest planets found to date is thought to be caused by the stellar wind interacting with the magnetic field surrounding the planet. In this thesis, a model for such an interaction is developed and is shown to be consistent with the observations, providing the first potential evidence for the presence of a magnetic field around an exoplanet. The model is then extended to predict the shape of near-ultraviolet light curves around HD 189733b, another hot Jupiter that orbits a very bright star. By looking at the variability in these transit light curves over time, the evolution and structure of the stellar wind is investigated. By tracking the position of bumps in the transit light curve, it is shown here that the data collected by missions such as Kepler has the potential to reveal stellar butterfly patterns. Such patterns are intrinsically linked with the stellar dynamo which governs the properties of the stellar magnetic field. Finally, the support of large-scale magnetic loops on young stars is investigated. These loops trap large amounts of hot, dense material and so a rapid destabilisation could lead to a flaring event, which could have devastating consequences for a nearby exoplanet.

description: As one of the world’s polluted regions, we assessed the association between ambient PM2.5 levels and acute lower and upper respiratory infection in India. We assessed 55,118 children from the 2015–2016 Demographic Health Survey in India using the information on levels of PM2.5 in 2015 and 2016 from the Atmospheric Composition Analysis Group. We used the generalized estimating equation for the analysis reported as odds ratios and 95% confidence intervals for every 10 µg/m3 increase and quartiles in PM2.5. Every 10 µg/m3 increase in levels of PM2.5 associated with acute upper respiratory infection (OR 1.02, 95%CI: 1.02–1.03) and acute lower respiratory infection (OR 1.05, 95%CI: 1.03–1.06). This association was confirmed by quartile exposure assessments. Mitigation efforts must be continued implementing higher restrictions in India to ensure safe levels of air.

description: This paper examines whether monetary expansion is a beggar- thyself or beggar- thy-neighbour policy. Obstfeld and Rogo¤ (1995) show that monetary expansion under producer currency pricing in- creases domestic and foreign overall welfare, in cases where the cross- country substitutability is high. If the cross-country substitutability is low, then monetary expansion is a beggar- thyself policy that re- duces domestic welfare and increases foreign welfare (Corsetti & Pe- senti 2001; Tille 2001). In this paper, we will show that regardless of whether the cross-country substitutability is high or low, monetary expansion is always a beggar-thyself policy in the short run.

description: Because little is known about cataract in pilots, we estimated prevalence by anonymously ascertaining all commercial airline pilots diagnosed with cataract 2011–2016 using the electronic Medical Records System of the Australian Civil Aviation Safety Authority. Of 14,163 Australian male commercial pilots licensed in 2011, 1286 aged ≥60 had biennial eye examinations showing a cataract prevalence of 11.6%. Among 12,877 pilots aged <60, based on compulsory eye examinations only when first licensed, prevalence was 0.5%. There was no significant difference by ambient ultraviolet (UV) radiation levels in state of residence though lowest prevalence was seen in the low-UV state of Victoria. Most cataract in pilots ≥60 years was bilateral and of mild severity, while cataract in pilots <60 were more likely to be unilateral and of greater severity.

description: There are processes in nature that resemble a true force but arise due to the minimization of the local energy. The most well-known case is the exchange interaction that leads to magnetic order in some materials. We discovered a new similar process occurring in connection with an electronic phase separation transition that leads to charge inhomogeneity in cuprate superconductors. The minimization of the local free energy, described here by the Cahn-Hilliard diffusion equation, drives the charges into regions of low and high densities. This motion leads to an effective potential with two-fold effect: creation of tiny isolated regions or micrograins, and two-body attraction, which promotes local or intra-grain superconducting pairing. Consequently, as in granular superconductors, the superconducting transition appears in two steps. First, with local intra-grain superconducting amplitudes and, at lower temperature, the superconducting phase or resistivity transition is attained by intergrain Josephson coupling. We show here that this approach reproduces the main features of the cuprates phase diagram, gives a clear interpretation to the pseudogap phase and yields the position dependent local density of states gap $Δ(\vec r)$ measured by tunnelling experiments.

Globular cluster systems as tracers of environmental effects on Virgo early-type dwarfs

description: Early-type dwarfs (dEs) are by far the most abundant galaxy population in nearby clusters. Whether these objects are primordial, or the recent end-products of the different physical mechanisms that can transform galaxies once they enter these high-density environments, is still a matter of debate. Here we present a novel approach to test these scenarios by comparing the properties of the globular cluster systems (GCSs) of Virgo dEs and their potential progenitors with simple predictions from gravitational and hydrodynamical interaction models. We show that low-mass (Mstar < 2E8 Msun) dEs have GCSs consistent with being the descendants of gas-stripped late-type dwarfs. On the other hand, higher mass dEs have properties -including the high mass specific frequencies of their GCSs and their concentrated spatial distribution within Virgo- incompatible with a recent, environmentally-driven evolution. They mostly comprise nucleated systems, but also dEs with recent star formation and/or disc features. Bright, nucleated dEs appear to be a population that has long resided within the cluster potential well, but have surprisingly managed to retain very rich and spatially extended GCSs - possibly an indication of high total masses. Our analysis does not favour violent evolutionary mechanisms that result in significant stellar mass losses, but more gentle processes involving gas removal by a combination of internal and external factors, and highlights the relevant role of initial conditions. Additionally, we briefly comment on the origin of luminous cluster S0s.

description: This paper systematically investigates whether different kinds of personality characteristics influence entrepreneurial development. On the basis of a large, representative household panel survey, we examine the extent to which the Big Five traits and further personality characteristics, which are more specifically related to entrepreneurial tasks, influence entry into self- employment and survival of self-employed persons in Germany. The empirical analysis reveals that among the specific characteristics in particular “risk attitudes” and “locus of control” have strong effects on entry and survival. With respect to the Big Five approach, in particular the traits “openness to experience” and “extraversion” and to a lower extent “agreeableness” and “neuroticism” help to explain entrepreneurial development. The explanatory power of the Big Five is comparable to one of the most prominent determinants of entrepreneurship – education – and approximately three times larger than parental selfemployment.

description: Generous income support programs as provided by European welfare states have often been blamed to reduce work incentives for lower income classes and to increase durations of unemployment. Standard studies measure work incentives based on annual income concepts. This paper analyzes how work incentives inherent in the German tax-benefit system evolve when extending the time horizon to three years (long-term). Participation tax rates are computed for 3-year periods 1995-1997 and 2005-2007 to reveal potential effects of the labor market reforms between 2003 and 2005. Results show that long-term work incentives increased even more than short-term work incentives. Particularly for middle-income individuals, this is largely explained by the abolition of earnings-related unemployment assistance.

description: The present paper explores the extent to which new joint General Budget Support (GBS) systems have been able to overcome the problems of aid dependency and negative fiscal incentives that can potentially result from high levels of on-budget aid. As approximately 90 percent of new joint GBS goes to sub-Saharan Africa, this analysis, which covers the period from 2000 to 2008, evaluates data from 37 sub-Saharan developing countries. According to fixed effect and system GMM estimations, joint GBS assistance – although highly discretionary – does not undermine recipients’ revenue mobilization efforts. Indeed, on the contrary, while aid in general has no measurable impact on recipients’ revenue performance, joint GBS programs are associated with higher revenue mobilization. This suggests that on-budget aid delivered under well-targeted conditionality successfully mitigates adverse fiscal incentives while substantially enhancing recipients’ fiscal space.

description: Type IIP (Plateau) Supernovae are the most commonly observed variety of core collapse events. They have been detected in a wide range of wavelengths from radio, through optical to X-rays. The standard picture of a type IIP supernova has the blastwave interacting with the progenitor's circumstellar matter to produce a hot region bounded by a forward and a reverse shock. This region is thought to be responsible for most of the X-ray and radio emission from these objects. Yet the origin of X-rays from these supernovae is not well understood quantitatively. The relative contributions of particle acceleration and magnetic field amplification in generating the X-ray and radio emission need to be determined. In this work we analyze archival Chandra observations of SN 2004dj, the nearest supernova since SN 1987A, along with published radio and optical information. We determine the pre-explosion mass loss rate, blastwave velocity, electron acceleration and magnetic field amplification efficiencies. We find that a greater fraction of the thermal energy goes into accelerating electrons than into amplifying magnetic fields. We conclude that the X-ray emission arises out of a combination of inverse Compton scattering by non-thermal electrons accelerated in the forward shock and thermal emission from supernova ejecta heated by the reverse shock.

description: In this paper we apply conjoint analysis as an empirical method to study the influence of tax labeling and tax earmarking on the perceived tax burden. As reference for the individual behavior we use the model of a rational utility maximizer described by the economic theory. We determine a significant influence of the labeling and the earmarking of taxes. We can show that the labeling and earmarking effect can decrease the perceived tax burden for the test persons which results in a deviation from a (rational) consumption maximizing behavior. These results give important implications for tax policy regarding further reforms of the tax and contribution system.

description: An unduly neglected implication of the choice of the tax unit is its impact on the consumption risk carried by taxpayers. As compared to individual taxation, joint taxation with income splitting provides couples with more insurance against the risk of earning inability for one of the spouses. If that risk is not insurable in markets, replacing individual taxation with joint taxation with income splitting can generate a Pareto-improvement.

description: We consider a mesoscopic circuit in the quantum Hall effect regime comprising two synchronized single-particle sources emitting particles into a Mach-Zehnder interferometer. While particles from one source can possibly interfere at the interferometer output, particles from the second source are injected directly into one of the interferometer's arms and are used to create tunable and coherent suppression of interference. If particles from the two different sources collide at the interferometer output the magnetic-flux dependence of the charge transferred to one of the output contacts is suppressed. In contrast the interference pattern in the current at a fixed time is preserved and the impact of the second source manifests itself in a time-dependent phase-shift.

description: Incentives to invest in higher education are affected by both the direct wage effect of human capital investments and the indirect wage effect resulting from lower unemployment risks and shorter spells in unemployment associated with higher educated. We analyse the returns to education in Austria, Germany, Italy, Sweden and the United Kingdom, countries which differ significantly regarding both their education systems and labour market structure. We estimate augmented Mincerian wage equations accounting for the effects of unemployment on individual wages using EU-SILC data. Across countries we find a high variation of the effect of education on unemployment duration. Overall, the returns to education are estimated to be the highest in the UK, and the lowest for Sweden. A wage decrease due to time spent in unemployment results in a decline in the hourly wages in Austria, Germany and Italy.

description: The Nonlinear Schroedinger Equation (NLSE) with a random potential is motivated by experiments in optics and in atom optics and is a paradigm for the competition between the randomness and nonlinearity. The analysis of the NLSE with a random (Anderson like) potential has been done at various levels of control: numerical, analytical and rigorous. Yet, this model equation presents us with a highly inconclusive and often contradictory picture. We will describe the main recent results obtained in this field and propose a list of specific problems to focus on, that we hope will enable to resolve these outstanding questions.

Correlated interaction fluctuations in photosynthetic complexes

description: The functioning and efficiency of natural photosynthetic complexes is strongly influenced by their embedding in a noisy protein environment, which can even serve to enhance the transport efficiency. Interactions with the environment induce fluctuations of the transition energies of and interactions between the chlorophyll molecules, and due to the fact that different fluctuations will partially be caused by the same environmental factors, correlations between the various fluctuations will occur. We argue that fluctuations of the interactions should in general not be neglected, as these have a considerable impact on population transfer rates, decoherence rates and the efficiency of photosynthetic complexes. Furthermore, while correlations between transition energy fluctuations have been studied, we provide the first quantitative study of the effect of correlations between interaction fluctuations and transition energy fluctuations, and of correlations between the various interaction fluctuations. It is shown that these additional correlations typically lead to changes in interchromophore transfer rates, population oscillations and can lead to a limited enhancement of the light harvesting efficiency.

description: The time domain has been identified as one of the most important areas of astronomical research for the next decade. The Virtual Observatory is in the vanguard with dedicated tools and services that enable and facilitate the discovery, dissemination and analysis of time domain data. These range in scope from rapid notifications of time-critical astronomical transients to annotating long-term variables with the latest modeling results. In this paper, we will review the prior art in these areas and focus on the capabilities that the VAO is bringing to bear in support of time domain science. In particular, we will focus on the issues involved with the heterogeneous collections of (ancillary) data associated with astronomical transients, and the time series characterization and classification tools required by the next generation of sky surveys, such as LSST and SKA.

description: In diesem Beitrag werden die Beschäftigungswirkungen von Lohnsubventionen und eines Mindestlohnes für Deutschland analysiert. Studien zum Mindestlohn im Baugewerbe und Simulationen zu einem allgemeinen Mindestlohn weisen einhellig auf Beschäftigungsverluste durch einen gesetzlichen Mindestlohn für die Bundesrepublik hin. Die Größenordnung hängt vom Mindestlohnniveau, Gütermarktreaktionen und der Reichweite des Mindestlohnes (Einschluss Auszubildender, geringfügig Beschäftigter) ab. Bei einem Mindestlohn von 7,5 € pro Stunde und elastischer Güternachfrage schätzen wir einen Gesamtverlust von ca. 220.000, insbesondere geringfügig Beschäftigten. Evaluationen bestehender Lohnsubventionen finden nur geringe Arbeitsanreizeffekte. Im Beitrag wird alternativ der aufkommensneutral gestaltete „Beschäftigungsbonus“, der geringe Stundenlöhne und nicht niedrige Erwerbseinkommen subventioniert, betrachtet. Dieser würde ein zusätzliches Arbeitsangebot von ca. 80.000 Personen bzw. ein zusätzliches Stundenangebot von etwa 420.000 Vollzeitäquivalenten induzieren. In Kombination mit einem allgemeinen Mindestlohn wären arbeitnehmerseitige Lohnsubventionen ineffektiv. Die Simulationsergebnisse zeigen, dass in diesem Fall arbeitgeberseitige Lohnsubventionen die infolge des Mindestlohnes gestiegenen Arbeitskosten kompensieren und Beschäftigungsverluste im Niedriglohnbereich teilweise verringern können.

description: The X-ray source 1E 161348-5055 lies at the centre of the 2-kyr-old supernova remnant RCW 103. Owing to its 24-ks modulation, orders-of-magnitude flux variability over a few months/years, and lack of an obvious optical counterpart, 1E 161348-5055 defies assignment to any known class of X-ray sources. Starting from April 2006, Swift observed 1E 161348-5055 with its X-ray telescope for 2 ks approximately once per month. During the five years covered, the source has remained in a quiescent state, with an average observed flux of 1.7e-12 erg/cm^2/s (1-10 keV), about 20 times lower than the historical maximum attained in its 1999-2000 outburst. The long time-span of the Swift data allows us to obtain an accurate measure of the period of 1E 161348-5055 [P = 24030.42(2) s] and to derive the first upper limit on its period derivative (|dP/dt| < 1.6e-9 s/s at 3 sigma).

SSC Emission as the Origin of the Gamma Ray Afterglow Observed in GRB 980923

description: GRB 980923 was one of the brightest bursts observed by the Burst and Transient Source Experiment (BATSE). Previous studies have detected two distinct components in addition to the main prompt episode, which is well described by a Band function. The first of these is a tail with a duration of approx. 400s, while the second is a high-energy component lasting approx. 2s. We summarize the observations, and argue for a unified model in which the tail can be understood as the early gamma-ray afterglow from forward shock synchrotron emission, while the high-energy component arises from synchrotron self-Comtpon (SSC) from the reverse shock. Consistency between the main assumption of thick shell emission and agreement between the observed and computed values for fluxes, break energies, starting times and spectral indices leads to a requirement that the ejecta be highly magnetized.
