Luminosity functions of Lyman-alpha emitters at z=6.5, and z=5.7: evidence against reionization at z=6

description: Lyman-alpha emission from galaxies should be suppressed completely or partially at redshifts beyond reionization. Without knowing the instrinsic properties of galaxies at z = 6.5, this attenuation is hard to infer in any one source, but can be infered from a comparison of luminosity functions of lyman-alpha emitters at redshifts just before and after reionization. We combine published surveys of widely varying depths and areas to construct luminosity functions at z=6.5 and 5.7, where the characteristic luminosity L_star and density phi_star are well constrained while the faint-end slope of the luminosity function is essentially unconstrained. Excellent consistency is seen in all but one published result. We then calculate the likelihood of obtaining the z=6.5 observations given the z=5.7 luminosity function with (A) no evolution and (B) an attenuation of a factor of three. Hypothesis (A) gives an acceptable likelihood while (B) does not. This indicates that the z=6.5 lyman-alpha lines are not strongly suppressed by a neutral intergalactic medium and that reionization was largely complete at z = 6.5.

description: We propose a novel type of color magnetic condensation originating from magnetic monopoles so that it provides the mass of off-diagonal gluons in the Yang-Mills theory. This dynamical mass generation enables us to explain the infrared Abelian dominance and monopole dominance by way of a non-Abelian Stokes theorem, which supports the dual superconductivity picture of quark confinement. Moreover, we show that the instability of Savvidy vacuum disappears by sufficiently large color magnetic condensation.

description: China’s energy consumption for agricultural production has relied on petroleum and coal with relatively low input from power and other types of energy for a long time. Projections indicate that as China’s existing development trend leads to substantial growth of energy demand for agricultural production, such a long term irrational energy consumption pattern would unlikely be able to meet the needs of the country’s developing agricultural sector. As such, it is recommended that China’s agricultural sector should follow the national energy development strategy guideline by gradually increasing the use of wind power, solar energy, biomass and other new energy sources while advancing technological innovations on traditional energy sources. Meanwhile, as the consumption structure of three major energy sources (i.e. petroleum, coal, and power) is optimized, development and application of biomass from agriculture as raw materials for alternative energy should be enhanced. Lastly, the development and application of wind power, solar energy, and hydropower in agricultural production should be increased in areas where appropriate.

description: Many key industrial processes, from electricity production, conversion and storage to electrocatalysis or electrochemistry in general, rely on physical mechanisms occurring at the interface between a metallic electrode and an electrolyte solution, summarized by the concept of electric double layer, with the accumulation/depletion of electrons on the metal side and of ions on the liquid side. While electrostatic interactions play an essential role on the structure, thermodynamics, dynamics and reactivity of electrode-electrolyte interfaces, these properties also crucially depend on the nature of the ions and solvent, as well as that of the metal itself. Such interfaces pose many challenges for modeling, because they are a place where Quantum Chemistry meets Statistical Physics. In the present review, we explore the recent advances on the description and understanding of electrode-electrolyte interfaces with classical molecular simulations, with a focus on planar interfaces and solvent-based liquids, from pure solvent to water-in-salt-electrolytes.
Highly polarized injection luminescence in forward-biased ferromagnetic-semiconductor junctions at low spin polarization of current

description: We consider electron tunneling from a nonmagnetic $n$-type semiconductor ($n$-S) into a ferromagnet (FM) through a very thin forward-biased Schottky barrier resulting in efficient extraction of electron spin from a thin $n$-S layer near FM-S interface at low spin polarization of the current. We show that this effect can be used for an efficient polarization radiation source in a heterostructure where the accumulated spin polarized electrons are injected from $n$-S and recombine with holes in a quantum well. The radiation polarization depends on a bias voltage applied to the FM-S junction.

description: In this paper, we investigate the enstrophy dynamics in relation to objective Eulerian coherent structures (OECSs) and their impact on the enstrophy and scalar transport near the turbulent/non-turbulent interface (TNTI) in flows with and without stable stratification. We confirm that vortex-stretching produces enstrophy inside the boundaries of the OECSs, while viscous diffusion transfers the enstrophy across the boundaries of the structures. Although often overlooked in the literature, viscous dissipation of enstrophy within the boundaries of vortical structures is significant. Conversely, for the weakly stratified flows also investigated here, the effect of the baroclinic torque is negligible. We provide evidence that the OECSs advect the passive/active scalar and redistribute it via molecular diffusion. Finally, we use conditional analysis to show that the typical profiles of the enstrophy and scalar transport equation terms across the TNTI are compatible with the presence of OECSs positioned at the edge between the turbulent sublayer and the turbulent core region. We show that when these profiles are further conditioned to the presence of OECSs, their magnitude is considerably higher.

description: According to the data of practical GDP time sequences from 1978 to 2009 provided by Henan Statistical Yearbook of every year, Hodrick-Prescott filter model is established, and it is disintegrated into tendency component (potential yield) and fluctuation component (yield gap). The critical division loci of filter model are 4 wave crest years (1980, 1988, 1996 and 2007), and 3 trough years (1984, 1992 and 2002). Thus since the opening up and reform, the economic growth fluctuation of Henan can be divided into 3 complete cycles and 2 incomplete cycles. Based on the economic situation and background within and without province, we preliminarily conclude the stage-characteristics of all growth cycles and the probable reasons of fluctuation. On the whole, the economic growth cycle of Henan takes on astringency to some extent, and sustainability and stability are reinforced, showing the characteristics of growth-type cycle increasingly.

description: Today, in the era of industrial expansion of developing countries, the Republic of Serbia strives to maintain the required level of progress and join the European Union. On this path of transition, it is necessary to use the comparative advantages in relation to the countries of the region, but also the EU member states. Analysing the available data, it can be established that an important comparative advantage of Serbia lies in the agricultural sector. The aim of this paper is to point out the mentioned comparative advantages, primarily by using the historical-comparative method, and to provide a basis for further decision-making to economic policy makers at the regional and national level. The concept of agricultural and economic policy should be based on the complete revival of agriculture, its revitalization, financial consolidation, innovation and affirmation of the intensification of the production framework.
How immigrant students from Pacific Rim countries perceive science education in Canadian classrooms
Creators: name: Mitsis, Louis Andreas
Publisher: name: University of British Columbia
Year: 2009

description: This study documented the opinions and ideas of twelve immigrant students from Pacific Rim countries in a Canadian high school setting. Data was obtained by in-person, individual interviews. It was not very surprising to discover that there are major differences between Pacific Rim and Canadian science classrooms, as perceived and experienced by the students. Many of the stereotypes that educators hold of the Pacific Rim system of education were confirmed by several of the students that were interviewed. What was surprising is that many of the teaching methods used in the Pacific Rim system have been embraced by the students, and have been proven to support student success in science. After the completion of this study, it was difficult to determine which system of science education the students prefer. Most of the students interviewed stated that they generally disliked most of the methods and strategies used in their home countries. However, many of the students contradicted themselves by stating that the Canadian methods did not pose much of a challenge in order facilitate learning. To allow Pacific Rim immigrant students to adapt smoothly to our system of education, a combination of western and Pacific Rim methods should be incorporated. This study has implications for teachers who teach Pacific Rim immigrant students in secondary schools. Canadian science teachers, and all teachers in general, must not be too quick to judge and criticize the strategies and methods used by teachers in Pacific Rim countries. We must accept that some of their methods, regardless of the difference in philosophy, do work for many students. Canadian teachers should continue to use the strategies that they use comfortably, and try to incorporate parts of the Pacific Rim system. Perhaps this will allow Pacific Rim immigrant students to adapt to education system and our culture in a smoother fashion.

description: Existed studies have shown that crowd workers are more interested in taking similar tasks in terms of context, field, and required technology, rather than tasks from the same project. Therefore, it is important for task owners to not only be able to plan 'when the new task should arrive?' but also, to justify 'what the strategic task arrival plan should be?' in order to receive a valid submission for the posted task. To address these questions this research reports an empirical analysis on the impact of similar task arrival in the platform, on both tasks' success level and workers' performance. Our study supports that 1- A higher number of arrival tasks with similarity level greater than 70% will negatively impact on task competition level, 2- A bigger pool of similar open and arrival tasks would lead to lower worker attraction and elasticity, and 3- Workers who register for tasks with lower similarity level are more reliable to make a valid submission and 4- arriving task to the pool of 60% similar task will provide the highest chance of receiving a valid submission.

description: Based on the scope economic theory of “resource curse” and industrial clusters, the scale of sugar cluster is calculated by the outputs of sugarcane and sugar while the scale benefit of sugar cluster is measured by the productivity ( rate of sugar production), sales output ratio, industrial output value as well as profit margin. Positive analysis of the scale merit of sugar clusters in resource-rich area of southwestern Guangxi is conducted according to related statistics of Chongzuo City. And the primary problems of sugar clusters are pointed out. The profit created by sugar for the sugar industry in Chongzuo City has already been near capacity. The sugar industry is big but not strong. With much governmental interfernce, there is no effective connections and inadequte competitive forces among subjects of the clusters. The extention of industrial chain is limited. Therefore, measures for developing sugar clusters in resource-rich area of southwestern Guangxi are proposed. Industrial structure is to be adjusted to improve the sugarcane cultivation techniques. The industrial chain should be extended to increase the economic benefits of sugar industry. Industrial support is to be strengthened and capital output for sicence and technology increased. Price regualtion fund of grain sugar is to be established with coordination with the superior region. The transforming speed of savings to investment should be quickened to evade “resource curse”.

description: We report the discovery of a Lyman-alpha-emitting galaxy at redshift z=6.545 serendipitously identified in the course of spectroscopic follow-up of hard X-ray sources on behalf of the Serendipitous Extragalactic X-Ray Source Identification (SEXSI) survey. The line flux of the galaxy, 2.1e-17 erg/cm2/s, is similar to line fluxes probed by narrow-band imaging surveys; the 5.2 square-arcminutes surveyed implies a surface density of z~6.5 Lyman-alpha emitters somewhat higher than that inferred from narrow-band surveys. This source marks the sixth Lyman-alpha-emitting galaxy identified at z~6.5, a redshift putatively beyond the epoch of reionization when the damping wings of the neutral hydrogen of the intergalactic medium is capable of severely attenuating Lyman-alpha emission. By comparing the Lyman-alpha emitter luminosity functions at z~5.7 and z~6.5, we infer that the intergalactic medium may remain largely reionized from the local universe out to z~6.5.

description: Estimating the value consumers place on farm animal welfare (FAW) can predict the extent to which consumers are ready to support policy changes aimed at improving the welfare of farm animals and developing animal-friendly production systems that can also compete on markets. This study aimed at exploring consumer preferences and willingness-to-pay (WTP) for broiler meat in Germany which is certified as having been produced under a system that caters for FAW. In addition, logistic and linear regression models were estimated to examine the factors affecting consumers’ decision to buy certified FAW products. The data was obtained from a survey of 300 German broiler consumers, which was designed using the contingent valuation methodology. The results showed that 82% of the respondents were ready to buy certified FAW products. A majority of these (95%) were willing to pay an extra sum of about €1.5 for 1 kg of the certified FAW broiler fillets. This represents a price increase of about 27% in comparison with the actual price of conventional broiler fillets. The WTP estimates reveal that there is a potential for improvement of FAW standards in conventional broiler production. The magnitude of these estimates, however, shows that consumer WTP is below the actual price premium demanded by producers for existing animal-friendly programs for broiler production. This explains why the market for certified FAW broilers fails and calls for a policy change towards higher minimum standards of broiler welfare. Ziel dieser Studie ist es, Erkenntnisse über die Präferenzen der deutschen Verbraucher für das Wohlergehen von Nutztieren (farm animal welfare FAW) zu gewinnen. Erforscht wurde die Zahlungsbereitschaft für Hähnchenfleisch, welches FAW zertifiziert produziert wird. Außerdem wurden logistische und lineare Regressionsmodelle geschätzt, um die Faktoren zu bestimmen, welche die Verbraucher bei ihrer Kaufentscheidung für FAW zertifizierte Produkte beeinflussen. Die Daten wurden durch eine Umfrage bei 300 deutschen Hähnchenfleischverbrauchern ermittelt, wobei die kontingente Bewertungsmethode verwendet wurde. Die Ergebnisse zeigen, daß 82 % der Befragten bereit waren, FAW zertifizierte Produkte zu kaufen. Von diesen war die überwiegende Mehrheit (95 %) bereit, einen zusätzlichen Betrag von ca. 1,50 € pro kg für FAW zertifizierte Hähnchenfilets zu zahlen. Dies stellt einen Preisanstieg von ca. 27 % dar im Vergleich zu dem aktuellen Preis für konventionell produzierte Hähnchenfilets. Die zusätzliche Zahlungsbereitschaft der Verbraucher liegt jedoch unterhalb der aktuellen Preisprämie, die die Hersteller bestehender FAW-Programme in der Hähnchenproduktion verlangen. Dies erklärt, warum der Markt für zertifiziertes FAW-Geflügelfleisch nicht erfolgreich ist.

description: In this numerical study, we investigate the role of intrinsic heterogeneities of cardiac tissue due to M cells in the generation and maintenance of reentrant excitations using the detailed Luo-Rudy dynamic model. This model has been extended to include a description of the long QT 3 syndrome, and is studied in both one dimension, corresponding to a cable traversing the ventricular wall, and two dimensions, representing a transmural slice. We focus on two possible mechanisms for the generation of reentrant events. We first investigate if early-after-depolarizations occurring in M cells can initiate reentry. We find that, even for large values of the long QT strength, the electrotonic coupling between neighboring cells prevents early-after-depolarizations from creating a reentry. We then study whether M cell domains, with their slow repolarization, can function as wave blocks for premature stimuli. We find that the inclusion of an M cell domain can result in some cases in reentrant excitations and we determine the lifetime of the reentry as a function of the size and geometry of the domain and of the strength of the long QT syndrome.

description: Characterizing the relation between weight structure and input/output statistics is fundamental for understanding the computational capabilities of neural circuits. In this work, I study the problem of storing associations between analog signals in the presence of correlations, using methods from statistical mechanics. I characterize the typical learning performance in terms of the power spectrum of random input and output processes. I show that optimal synaptic weight configurations reach a capacity of 0.5 for any fraction of excitatory to inhibitory weights and have a peculiar synaptic distribution with a finite fraction of silent synapses. I further provide a link between typical learning performance and principal components analysis in single cases. These results may shed light on the synaptic profile of brain circuits, such as cerebellar structures, that are thought to engage in processing time-dependent signals and performing on-line prediction.

description: Agricultural production continues to shift to larger farms in the U.S. I show that the shift is persistent over time, large, and ubiquitous across commodities. I review theories of farm size, and classify three channels for analysis: 1) scale effects, through technological economies and managerial diseconomies; 2) the roles of relative factor prices and factor shares; and 3) policy and institutions. Finally, I evaluate the empirical evidence on the forces driving structural change, distinguishing between crops and livestock because of important differences in the role of scale economies and coordination, and I offer some directions for the future.

description: Socio-economic and institutional changes may accelerate land-use and land-cover change. Our goal was to explore the determinants of agricultural land abandonment within one agro-climatic and economic region of post-Soviet European Russia during the first decade of transition from a state-command to market-driven economy (between 1990 and 2000). We integrated maps of abandoned agricultural land derived from 30 m resolution Landsat TM/ETM+ images, environmental and socioeconomic variables and estimated logistic regressions. Results showed that post-Soviet agricultural land abandonment was significantly associated with lower average grain yields in the late 1980s, higher distance from the populated places, areas with low population densities, for isolated agricultural areas within the forest matrix and near the forest edges. Hierarchical partitioning showed that average grain yields in the late 1980s contributed the most in explaining the variability of agricultural land abandonment, followed by location characteristics of the land. While the spatial patterns correspond to the classic micro-economic theories of von Thünen and Ricardo, it was largely the macro-scale driving forces that fostered agricultural abandonment. In the light of continuum depopulation process in the studied region of European Russia, we expect continuing agricultural abandonment after the year 2000.

description: We present a deep optical survey of Uranus' Hill sphere for small satellites. The Subaru 8-m telescope was used to survey about 3.5 square degrees with a 50% detection efficiency at limiting red magnitude m = 26.1 mag. This magnitude corresponds to objects that are about 7 km in radius (assuming an albedo of 0.04). We detected (without prior knowledge of their positions) all previously known outer satellites and discovered two new irregular satellites (S/2001 U2 and S/2003 U3). The two inner satellites Titania and Oberon were also detected. One of the newly discovered satellites (S/2003 U3) is the first known irregular prograde of the planet. The population, size distribution and orbital parameters of Uranus' irregular satellites are remarkably similar to the irregular satellites of gas giant Jupiter. Both have shallow size distributions (power law indices q~2 for radii > 7 km) with no correlation between the sizes of the satellites and their orbital parameters. However, unlike those of Jupiter, Uranus' irregular satellites do not appear to occupy tight distinct dynamical groups in semi-major axis versus inclination phase space. Two groupings in semi-major axis versus eccentricity phase space appear to be statistically significant.

description: BACKGROUND: Non-alcoholic fatty liver is a condition characterized by excess lipid deposition in the hepatocytes of the liver without the excessive consumption of alcohol. The prevalence of NAFLD continues to increase in tandem with the rise of type 2 diabetes and obesity.

MATERIALS AND METHODS: This is a prospective, cohort, and interventional study in which subjects were randomized into test and control groups by the block randomization method. The TyG index was calculated for all the patients to explore the relationship between the TyG index and NAFLD. The KAP questionnaire was administered to all the patients at baseline and three subsequent follow-ups. Patients in the test group received structured education at every follow-up on NAFLD, while the control group patients received only at the final follow-up.

RESULTS: A significant reduction in the TyG index values was observed in the test group compared to that of the control group (p < 0.05), indicating improved glycemic and lipid control following pharmacist-led education. KAP scores showed a marked improvement in the test group with a significant increase in knowledge and practice regarding NAFLD management. The TyG index demonstrated a positive correlation with the presence and severity of NAFLD. Patients who received regular pharmacist-led counselling showed better adherence to lifestyle modifications and dietary recommendations.

CONCLUSION: Pharmacist-led education significantly improves the understanding, management, and control of NAFLD by reducing the TyG index and enhancing patient compliance with lifestyle modifications.

description: Svaki rat, kao posljedicu djelovanja sukobljenih strana, ima ljude koji stradaju. Nekada u prošlosti uglavnom su u oružanim sukobima stradali vojnici, dok su civili bili sekundarne žrtve, uglavnom pljačke i nasilja. No, vremena su se promijenila. Uslijed promijenjenog načina vođenja rata, civili postaju glavna meta napada, a moderni sukobi, zbog svoje sveobuhvatnosti, dobivaju novi naziv: "totalni rat". Sukobi u Bosni i Hercegovini u razdoblju od 1992. do 1995. godine nude sličan scenarij. Prema do sada dostupnim podacima oko 40% ubijenih i nestalih osoba u BiH su bili civili. Stotine hiljada drugih koji nisu ubijeni i nestali, pretrpjeli su različite oblike šteta. U vremenu mira, oni su aktivno legitimirani tražiti naknadu te štete. Taj “zadatak” međutim, nije nimalo lagan za njih.
Dynamic capital structure and partial adjustment frameworks

description: I compare ordinary least squares and the Kalman filter as possible estimation tools for partial adjustment models of dynamic capital structure. I find that the latter is more suited, as it can handle forms of endogeneity and measurement error. While the firms in my sample adjust their capital structure at different rates, I do not find any evidence that this adjustment is made according to a time-varying target. Furthermore, I construct a simple theoretical dynamic model with fixed capital adjustment costs. By investigating time series generated by this model, I conclude that partial adjustment frameworks may be inadequate for estimation. When fixed costs are present, estimates of a firm's speed of capital adjustment are biased.

description: Based on this work package previous reports (D4.1 Methodology for alternatives definition, prioritisation, and selection; and D4.2 Conceptual scenarios definition to enable decision support), each region has defined (elements, activities, and schedule) selected scenarios, reviewed them, and carried out a techno-economic evaluation with the goal of comparing region alternatives and selecting the optimum development scenario for Paris Basin, for Lusitania Basin, and for Ebro Basin; and, with lower detail but following the same approach, for Silesia Basin and Macedonia Basin. Those optimum developments will be built and evaluated in detail by each region team during next months, being the basis for the final investment decision report.

Every region developed and evaluated their region scenarios framed by its own objectives, using a fit for purpose approach: while the French team was focused on a pilot (pre-commercial) development, the Portuguese and Spanish teams have considered, in addition, a possible commercial development. Polish and Greek cases show a more general study for the full-life case. Therefore, the different regions development and timeframe are diverse from the very beginning, compiling a cluster of examples for possible applications in the future.

Noncoherent Joint Transmission Beamforming for Dense Small Cell Networks: Global Optimality, Efficient Solution and Distributed Implementation

description: We investigate the coordinated multi-point noncoherent joint transmission (JT) in dense small cell networks. The goal is to design beamforming vectors for macro cell and small cell base stations (BSs) such that the weighted sum rate of the system is maximized, subject to a total transmit power at individual BSs. The optimization problem is inherently nonconvex and intractable, making it difficult to explore the full potential performance of the scheme. To this end, we first propose an algorithm to find a globally optimal solution based on the generic monotonic branch reduce and bound optimization framework. Then, for a more computationally efficient method, we adopt the inner approximation (InAp) technique to efficiently derive a locally optimal solution, which is numerically shown to achieve near-optimal performance. In addition, for decentralized networks such as those comprising of multi-access edge computing servers, we develop an algorithm based on the alternating direction method of multipliers, which distributively implements the InAp-based solution. Our main conclusion is that the noncoherent JT is a promising transmission scheme for dense small cell networks, since it can exploit the densitification gain, outperforms the coordinated beamforming, and is amenable to distributed implementation.

description: Systemic economic transition is a process of determined radical institutional change, a process of building new institutions required by a market economy. Nowadays, the experience of transition countries with the implementation of new institutions could be reviewed as a method of economic development that despite similar singular steps has different effects on the domestic economic performance. The process of institutional change towards a market economy is determined by political will, thus the government plays an important role in carrying out the economic reforms. Among the variety of outcomes and effects the attention is drawn especially to economic growth that diverges significantly in different post-transition countries. The paper attempts to shed light upon the problem on the basis of institutional economics, of economics of innovation and partially of political economy of growth using an evolutionary, process-oriented perspective. In this context the issue central to the promotion of economic growth is the successful implementation of new institutions through governmental activities. The paper shows that under the conditions of bounded rationality and radical uncertainty economic growth is determined, inter alia, by the capacity for governmental learning.

description: We present protocols for multiparty data hiding of quantum information that implement all possible threshold access structures. Closely related to secret sharing, data hiding has a more demanding security requirement: that the data remain secure against unrestricted LOCC attacks. In the limit of hiding a large amount of data, our protocols achieve an asymptotic rate of one hidden qubit per local physical qubit. That is, each party holds a share that is the same size as the hidden state to leading order, with accuracy and security parameters incurring an overhead that is asymptotically negligible. The data hiding states have very unusual entanglement properties, which we briefly discuss.

description: Short-duration Gamma-ray bursts (GRBs) (\leq 2{\rm s}) have remained a mystery due to the lack of afterglow detection until recently. The models to interpret short GRBs invoke distinct progenitor scenarios. Here we present a generic analysis of short GRB afterglows, and calculate the optical lightcurves of short GRBs within the framework of different progenitor models. We show that all these optical afterglows are bright enough to be detected by the Ultraviolet and Optical Telescope (UVOT) on board the {\em Swift} observatory, and that different models could be distinguished with a well-monitored lightcurve. We also model the afterglow data of the recently discovered short burst GRB 040924. We find that the limited data are consistent with a low medium density environment which is consistent with the pre-concept of the compact-star merger progenitor model, although the models with a collapsar progenitor are not ruled out.

description: Diffractive photonic devices manipulate light via local and nonlocal optical modes. Local devices, such as metasurfaces, can shape a wavefront at multiple selected wavelengths, but inevitably modify light across the spectrum; nonlocal devices, such as grating filters, offer great frequency selectivity but limited spatial control. Here, we introduce a rational design paradigm using quasi-bound states in the continuum to realize multifunctional nonlocal devices: metasurfaces that produce narrowband spatially tailored wavefronts at multiple selected wavelengths and yet are otherwise transparent.
