Rapid solidification of Al-Cu droplets of eutectic composition was carried out using Impulse Atomization (a type of drop tube). Two distinct morphologies were observed: an irregular undulated eutectic assumed to form during recalescence, followed by a regular lamellar eutectic. The volume fraction of each morphology was measured and used to deduce the nucleation undercooling based on the hypercooling limit. A model of the eutectic solidification was developed assuming that the kinetics of the undulated and regular regions is the same and follows scaling laws established experimentally. The simulated solid fraction forming during recalescence matches the experimental undulated eutectic fraction. Furthermore, the heat balance confirms the adiabatic nature of the solidification during recalescence. Good agreement is found between the model and experimental measurements of lamellar spacing for the regular eutectic. However, the predicted spacing of the undulated eutectic is much lower than what is observed experimentally. This difference as well as the nature of this morphology is attributed to coarsening during the remaining of solidification of the very fine eutectic formed during recalescence.

description: Crowdfunding, Internet websites, and health care are only a few examples of markets in which agents make decisions not only on the basis of their own investigations and knowledge, but also on the basis of information from a "central planner" about other agents’ actions. While such reciprocal learning can be welfare-improving, it may reduce agents’ incentives to conduct their own investigations, and may lead to harmful cascades. We study the planner’s optimal policy regarding when to provide information and how much information to provide. We show that the optimum policy involves a delicate balance of hiding and revealing information.

description: We have analysed the light curve of the two brightest X-ray flares from the Galactic Center black hole, one flare observed by XMM-Newton on October 3, 2002 (Porquet et al. 2003), and the other flare observed by Chandra on October 26, 2000 (Baganoff et al. 2001). The power density spectra show five distinct peaks at periods of ~ 100 s, 219 s, 700 s, 1150 s, and 2250 s common to both observations within their estimated measurement uncertainties. The power density spectrum of the recently reported infrared flare of June 16, 2003 (Genzel et al. 2003) shows distinct peaks at two, if not three, periods (including the 1008 +/- 120 s infrared period), which are consistent with the X-ray periods. The remaining two periods could not be covered by the infrared measurements. Each period can be identified with one of the characteristic gravitational cyclic modes associated with accretion disks, i.e. either Lense-Thirring precession, Kepler orbital motion and the vertical and radial epicyclic oscillation modes, in such a way that a consistent value for the black hole mass of M_BH = 2.72^{+0.12}_{-0.19} x 10^6 M_odot and the angular momentum $a$ = 0.9939^{+0.0026}_{-0.0074} is obtained. The available data on M_BH derived from studies of the orbital motion of the S2 (S0-2) star (Schoedel et al. 2002, Ghez et al. 2003) agree with our findings. Finally we discuss some implications of the fairly high value for the angular momentum.
description: In this revised version (accepted by the A&A Editor, 9 pages), we use the formula for the Lense-Thirring precession given by Merloni et al. (1999), which is not restricted to the weak-field limit. Thereby we now obtain a unique solution for the mass and the angular momentum of the supermassive black hole

description: We study the complete evolution of a flat and homogeneous universe dominated by tachyonic matter. We demonstrate the attractor behaviour of the tachyonic inflation using the Hamilton-Jacobi formalism. We else obtain analytical approximations to the trajectories of the tachyon field in different regions. The numerical calculation shows that an initial non-vanishing momentum does not prevent the onset of inflation. The slow-rolling solution is an attractor.

Do Reservation Wages Decline Monotonically? A Novel Statistical Test

description: This paper develops a test for monotonicity of the regression function under endogeneity. The novel testing framework is applied to study monotonicity of the reservation wage as a function of elapsed unemployment duration. Hence, the objective of the paper is twofold: from a theoretical perspective, it proposes a test that formally assesses monotonicity of the regression function in the case of a continuous, endogenous regressor. This is accomplished by combining different nonparametric conditional mean estimators using either control functions or unobservable exogenous variation to address endogeneity with a test statistic based on a functional of a second order U-process. The modified statistic is shown to have a non-standard asymptotic distribution (similar to related tests) from which asymptotic critical values can directly be derived rather than approximated by bootstrap resampling methods. The test is shown to be consistent against general alternatives. From an empirical perspective, the paper provides a detailed investigation of the effect of elapsed unemployment duration on reservation wages in a nonparametric setup. This effect is difficult to measure due to the simultaneity of both variables. Despite some evidence in the literature for a declining reservation wage function over the course of unemployment, no information about the actual form of this decline has yet been provided. Using a standard job search model, it is shown that monotonicity of the reservation wage function, a restriction imposed by several empirical studies, only holds under certain (rather restrictive) conditions on the variables in the model. The test from above is applied to formally evaluate this shape restriction and it is found that reservation wage functions (conditional on different characteristics) do not decline monotonically.

description: Thermodynamics teaches that if a system initially off-equilibrium is coupled to work sources, the maximum work that it may yield is governed by its energy and entropy. For finite systems this bound is usually not reachable. The maximum extractable work compatible with quantum mechanics (``ergotropy'') is derived and expressed in terms of the density matrix and the Hamiltonian. It is related to the property of majorization: more major states can provide more work. Scenarios of work extraction that contrast the thermodynamic intuition are discussed, e.g. a state with larger entropy than another may produce more work, while correlations may increase or reduce the ergotropy.

description: Seagrass meadows and coral reefs along the coast of Saipan, a US commonwealth in the Northern Pacific, have been declining since the 1940s, possibly due to nutrient loading. This study investigated whether submarine groundwater discharge (SGD) contributes to nutrient loading and supports primary production on Saipan’s coast. SGD can be an important source of freshwater, nutrients, and other pollutants to coastal waters, especially in oceanic islands without well-developed stream systems. Ra and Rn isotopes were used as natural tracers of SGD. Nitrate, phosphate, and ammonium concentrations, ancillary water quality parameters, δ15 N and δ18 O of dissolved nitrate, and δ15 N of primary producer tissue were measured. Our results pointed to discharge of low-salinity groundwater containing elevated concentrations of sewage-derived N at specific locations along Saipan’s coast. High SGD areas had lower salinity and pH, higher dissolved inorganic nitrogen concentrations, and elevated primary producer δ15 N, indicative of sewage nitrogen inputs. We estimated that SGD could support 730–6400 and 3000–15,000 mol C d−1 of primary production in Tanapag and Garapan Lagoons, respectively, or up to approximately 60% of primary production in Garapan Lagoon. Efforts to improve water quality, reduce nutrient loading, and preserve coastal ecosystems must account for groundwater, since our results demonstrate that it is an important pathway of nitrogen delivery.

description: By studying a monopoly investment decision, this paper considers the informativeness of customers complaints in contexts characterised by the absence of direct benefits and free riding incentives. Neither the consumer nor the regulator observe the firm’s investment, they only observe a realisation of quality that is related to investment in a first order stochastically dominance sense. After observing quality, consumers decide whether to complain based on the difference between the realised quality and a reference point defined by their rational expectations. If a high proportion of consumers complain, the regulator punishes the firm. The paper shows that the absence of a reference point results either in no complaints in equilibrium or in the proportion of complaints being independent of the realised level of quality. The main result is that complaints are not always informative about the level of quality being delivered by the firm. Indeed, a firm might be punished despite of investment levels being high if consumers expected high quality or, on the contrary, not being punished when investing is low if consumers expected low quality. Furthermore, this lack of informativeness can be worsened by a repeated interaction between the firm and the consumers.

description: Structural changes in giant DNA induced by the addition of the flexible polymer PEG were examined by the method of single-DNA observation. In dilute DNA conditions, individual DNA assumes a compact state via a discrete coil-globule transition, whereas in concentrated solution, DNA molecules exhibit an extended conformation via macroscopic phase segregation. The long axis length of the stretched state in DNA is about 1000 times larger than that of the compact state. Phase segregation at high DNA concentrations occurs at lower PEG concentrations than the compaction at low DNA concentrations. These opposite changes in the conformation of DNA molecule are interpreted in terms of the free energy, including depletion interaction.

description: The successful implementation of any agricultural and food security policy hinges upon the effectiveness of an existing system used to formulate, implement and monitor policies. A policy that is inclusive in its formulation and established through the use of reliable evidence, and effectively implemented and monitored, is likely to promote sector transformation. In recognition of the importance of the quality of the policy formulation processes and the supporting institutional architecture, the Tanzania ASPIRES project under the Food Security Policy Innovation Lab (FSP) funded by the United State Agency for International Development (USAID) was established in 2016 with the main objective of accelerating the adoption of more effective policies and programs, to drive a broad based agricultural sector growth, improve food security and nutrition, and reduce poverty. This paper reports on the perceived quality and institutional architecture of agriculture and food security policy processes as it existed in 2015, to serve as a baseline qualitative indicators of the policy environment in Tanzania. The assessment is based on a survey involving 89 stakeholders from the government, NGO, private sector, donor, and research communities that are active in the agriculture and food security policy space in Tanzania. The overall results indicate that while there are positive aspects of the policy processes that are in place, there is scope for improvements. There is need to ensure that Tanzania’s policy process is better informed by effectively utilizing available empirical evidence and enabling the availability and accessibility of reliable sector performance data. This will in turn enable a consistent assessment of the performance of the sector and appropriate allocation of resources for policy implementation.

description: Fairness emerges as a relevant factor in redistributive preferences in surveys and experiments. We study experimentally the impact of varying the probability with which players are assigned to initial positions in Ultimatum Games (UGs). In the baseline case players have equal opportunities of being assigned the proposer position ñ arguably the more advantaged one in UGs. Chances become increasingly unequal across three treatments. We also manipulate the inter-temporal allocation of opportunities over rounds. We Önd that: (1) The more initial chances are distributed unequally, the lower the acceptance rates of a given o§er; consequently, o§ers increase; (2) Being assigned a mere 1% chance of occupying the proposer role compared to none, signiÖcantly increases acceptance rates and decreases o§ers; (3) Players accept even extreme amounts of unequal chances within each round in exchange for overall equality of opportunities across rounds. Procedural fairness - both static and dynamic - has clear relevance for individuals.

description: The presented research aimed to perform geophysical modelling (gravity and geoid) and to evaluate the spatio-temporal variation of the marine geological data (distribution and depth of earthquakes) using combination of the Generic Mapping Tools (GMT) and available sources from the International Seismological Centre (ISC-EHB) that produce data on earthquakes as part of seismic survey and regional research projects. The target study area is a Philippine Sea basin (PSB) with two focused marginal areas: Philippine Trench and Mariana Trench, two hadal trenches located in the places of the tectonic plates subduction. Marine free-air gravity anomaly in the PSP shows higher values (>80 mGal) of the gravity fields structure at the volcanic areas and Philippine archipelago. Current study presented comparative geophysical analysis, and mapping free-air gravity and geoid in the Philippine Sea basin area. As a result of this study, the average level of earthquakes located in the Philippine Trench and Mariana Trench areas were compared, and those located in the Philippine archipelago are determined to be in the souther-western part (area of west Mindanao, south-west Visayas islands), while Luzon Islands shown shallower located earthquakes. The results on the Mariana Trench segment shown shallower located earthquakes compared of the other marginal regions of the Philippine Sea Basin. Current paper contributes to the studies on natural hazards through visualization and analysis of the earthquakes activities (occurrence and magnitude intensity), due to increasing interest to the problems of seismicity in the Pacific Ocean, which may have environmental effects causing harmful consequences and possible risks for coastal population of the Philippine islands through aftershocks and tsunami.

description: The spatial distribution of exoplanets in the Galaxy is important for our understanding of planet formation and evolution. We aim to determine the spatial gradients of exoplanet occurrence in the Solar neighbourhood and in the vicinity of open clusters. We combined Kepler and Gaia DR2 data for this purpose, splitting the volume sampled by the Kepler mission into certain spatial bins. We determined an uncorrected and bias-corrected exoplanet frequency and metallicity for each bin. There is a clear drop in the uncorrected exoplanet frequency with distance for F-type stars, a decline with increasing distance along the Galactic longitude l=90 deg, and a drop with height above the Galactic plane. We find that the metallicity behaviour cannot be the reason for the drop of the exoplanet frequency around F stars with increasing distance. We argue that the above-mentioned gradients of uncorrected exoplanet frequency result from a single bias of undetected smaller planets around fainter stars. When we correct for observational biases, most of these gradients in exoplanet frequency become statistically insignificant. Only a slight decline of the planet occurrence with distance for F stars remains significant at the 3 sigma level. Apart from that, the spatial distribution of exoplanets in the Kepler field of view is compatible with a homogeneous one. At the same time, we do not find a significant change in the exoplanet frequency with increasing distance from open clusters. As a byproduct, we identified six exoplanet host star candidates that are members of open clusters. Four of them are in the NGC 6811 (KIC 9655005, KIC 9533489, Kepler-66, Kepler-67) and two belong to NGC 6866 (KIC 8396288, KIC 8331612). Two out of the six had already been known to be cluster members.

description: Over the past two decades, food systems in Sub Saharan Africa (SSA) have transformed rapidly. This transformation is driven by several factors including increased incomes and rapid urbanization rates which have caused consumption patterns to change significantly (Tschirley et al. 2017). Two characteristics of this transformation are the rise in food purchases (particularly by rural households) and the consumption of processed and packaged foods. In Nigeria for example, nationally representative data in 2015 reveals that almost 75% of foods consumed are purchased with over 65% processed in some form (Liverpool-Tasie et al., 2016). These high and increasing rates of purchased and processed foods are revealed broadly across the continent and in both rural and urban areas within countries (Tschirley et al., 2015; Liverpool-Tasie et al., 2016). Increased consumption of processed foods can be met from two sources; domestically processed foods and imports. In addition to foreign exchange savings, domestically produced processed foods create numerous opportunities for domestic entrepreneurs and farmers; the potential source of inputs for these industries. However, they also raise key concerns related to food safety and nutrition. Consequently, regulations are necessary to ensure that these new products meet necessary food safety and nutrition standards. Similarly, incentives need to be aligned properly for economic agents along food supply chains for food safety considerations to be widely incorporated into these supply chains. Domestic production of substitutes for previously imported items (to meet increasing local demand for processed foods) in any developing country should be an area of key policy concern. Though there is evidence of a rise in domestic processed food production and consumption (Liverpool-Tasie et al. 2016; Tschirley et al., 2015) the extent to which standards exist and are enforced for domestic processed foods is not well understood in many countries in Sub Saharan Africa. Consequently, this paper explores one particular issue related to food safety in Nigeria; the presence and potential effects of aflatoxins along Nigeria’s maize value chain.

description: We show that personality traits mediate the effect of income on Life Satisfaction. The effect is strong in the case of Neuroticism, which measures the sensitivity to threat and punishment, in both the British Household Panel Survey and the German Socioeconomic Panel. Neuroticism increases the usually observed concavity of the relationship: Individuals with higher Neuroticism score enjoy income more than those with lower score if they are poorer and enjoy income less if they are richer. When the interaction between income and neuroticism is introduced, income does not have significant effect on his own. To interpret the results, we present a simple model where we assume that (i) Life Satisfaction is dependent from the gap between aspired and realized income, and this is modulated by Neuroticism and (ii) income increases in aspirations with a slope less than unity, so that the gap between aspired and realized income increase with aspirations. From the estimation of this model we argue that poorer tend to overshoot in their aspiration, while rich tend to under-shoot. The estimation of the model also shows substantial effect of traits on income.

description: We study the proximity effect in hybrid structures consisting of superconductor and ferromagnetic insulator separated by a normal diffusive metal (S/N/FI structures). These stuctures were proposed to realize the absolute spin-valve effect. We pay special attention to the gaps in the density of states of the normal part. We show that the effect of the ferromagnet is twofold: It not only shifts the density of states but also provides suppression of the gap. The mechanism of this suppression is remarkably similar to that due to magnetic impurities. Our results are obtained from the solution of one-dimensional Usadel equation supplemented with boundary conditions for matrix current at both interfaces.

Downhole tools made of dissolvable alloys (DAs) are getting more attractive, especially with the difficulties that arise from drilling wellbores with longer lateral distances. To date, most of the DAs are based on Al alloys (AAs) or Mg alloys, which offer undesirable mechanical properties. This work aims to develop a series of new Al-based DAs, providing high material strength and fast corrosion rates, for hydraulic fracturing applications. Given the enormous possibilities in tunning the structures and compositions of potential DAs, a literature review was first done to summarize the effects of various alloying elements on the microstructures, mechanical properties, and corrosion resistance of AAs. The main chemistry in downhole environments is KCl while the abundant electrochemical data of AAs are in NaCl electrolytes. In order to maximize the available electrochemical data of AAs, the effect of the associate cation type (K+ vs. Na+) on the corrosion of selected alloys was investigated by comparing the electrochemical values obtained under the same Cl− molar concentration of KCl vs. NaCl solutions. To facilitate the design and elemental selection, Taguchi’s method was utilized to change the chemistry of a commercial alloy (AA 7075) by adding various elements (such as Cu, Ga, Ag, Sn, In, Zn, Cr, and Zr). Scheil-Gulliver model was used to predict the potential phases formed as well as their amounts. Based on the review and simulation results, a few candidate alloys were targeted which were anticipated to potentially yield high mechanical properties and active corrosion behavior. It is believed that the experimental and simulation methods employed in the work will facilitate the development of the most promising DA compositions for downhole applications.

description: In Mali, over 60% of the population lives in rural areas and about half of them live under the poverty line (World Bank 2017). Since most rural people depend on agriculture as their main source of livelihood, increasing agricultural productivity is crucial for decreasing poverty. This article explores the effectiveness of nitrogen fertilizer for increasing dry-land cereal crop yields. Using the LSMS-ISA and a Sudan-Savanna dataset, simple econometric analysis suggests there is little effect of nitrogen fertilizer use on crop yields. However, when we account for the endogeneity of fertilizer use, we find yield response rates that are within the range reported in the literature. As expected, sorghum yields have a lower response to fertilizer than maize yields. Dryland cereal yield responses to fertilizer are stronger in the Sudan Savanna region (sample) than nationwide (nationally-representative dataset), highlighting the importance of agroecological factors and farming system. Soil texture and practices (anti-erosion structures) affect both yields and estimated effects of fertilizer. We also find phosphorus to be a binding constraint in increasing agricultural productivity. While most emphasis in the literature is placed on understanding nitrogen fertilizer use, it is crucial to promote balanced use of fertilizers so that other complementary nutrients are available in the soil.

description: To cope with and reverse the worrying trend of widespread soil degradation, declining productivity and increased vulnerability of African food systems to climate change requires a holistic approach to sustainable intensification, which recognizes that action is required within the agricultural sector and beyond. This includes approaches that enable farmers to make long-term soil fertility-augmenting investments and more effective public investments that help farmers identify best practices under the wide range of micro-environments in the region. More broadly, it requires developing policies that make labor and financial markets more flexible and supportive of climate-smart outcomes. This may include: 1) substantially increase investments in public agricultural research and participatory extension services in tandem with efforts to identify more effective modes of implementing such programs; 2) prioritize macro-economic stability, with an emphasis on low inflation and borrowing rates, to enable greater investment in the food system and beyond; 3) transform public subsidies in ways that support the development of markets for organic matter, in particular harvest waste from growing urban areas (e.g., livestock production yards, sawdust mills, waste from retail food markets) as sources of organic compost for farm production; 4) develop policy frameworks to legitimize and strengthen emergent land rental markets; 5) improve labor market flexibility and foreign direct investment policies, coupled with a social safety net fund; and 6) substantially reform staple food market policy in order to create a level playing field for alternative crops and livestock systems. Given the enormity of the challenges facing food systems in the context of rapid population growth and climate change, and the importance of collective action in address them, public sector action and effective use of scarce public expenditures to agriculture will be decisive in achieving sustainable agricultural productivity in the r egion. Once enacted, the proposals made here will take time togenerate their full impacts. That is why there is no time to waste in getting started.

A playful city in the cards : sharing power in game design by extending the card metaphor
Creators: name: Stokes, Benjamin
Publisher: name: American University

description: To democratize the power of games for smart cities, we are refining Hive Mechanic, an open-source game engine for embedding play with text messages, city data streams, and the Internet of Things (IoT). City-specific games have the potential to affect social issues, including to address regional economics and health disparities that vary by zip code. However, collaboration in design is notoriously difficult - and programming skills are often lacking in urban planners, artists, and ordinary residents. Rather than propose a consumer app for mobile phones, this project investigates the potential of coordinating play from a neighborhood server. More importantly, the authoring tool seeks to democratize design by aligning the use of print and digital "cards"in the design process to express feedback loops and interactive sequences without requiring any traditional software coding experience. We argue that for game design in particular, paper prototyping is especially important - and that authoring tools can expand participation by embracing a "card metaphor"to extend the power of paper prototyping into online authoring tools. This work in progress is a nine-month case study of using Hive Mechanic, including for public art, crowd-sourced mapping, and a transmedia scavenger hunt.
