description: Many researchers are interested in making predictions for macroeconomic variables, but few of them studied the accuracy of their forecasts. The problem is essential, especially in crisis periods, because from many forecasts made for the same indicator only one or few are the most accurate. In this research, some alternative forecasts for the annual rate of change for the HICP for EU were developed. Their accuracy was evaluated and compared with the accuracy of SPF predictions. All the proposed predictions for January 2010-May 2012 (those based on a random walk developed for 1997-2009, combined forecasts, the median and the mean of forecasts, predictions based on different econometric models that take into account the previous SPF forecasts) were not more accurate than the naïve forecasts or SPF ones. A considerably improvement of the accuracy was gotten for predictions based on mean error of SPF expectations for 1997-2009 and the previous registered value. This empirical strategy of building more accurate forecasts was better than the classical theoretical approaches from literature, but it is still less accurate than the naïve forecasts that could be made for UE inflation rate. The point forecasts based on the lower limit of intervals built using root mean squared indicator generated an improvement in accuracy, outperforming the SPF predictions and also the naïve forecasts.

description: Growth mindset interventions foster students' beliefs that their abilities can grow through effort and appropriate strategies. However, not every student benefits from such interventions - yet research identifying which student factors support growth mindset interventions is sparse. In this study, we utilized machine learning methods to predict growth mindset effectiveness in a nationwide experiment in the U.S. with over 10,000 students. These methods enable analysis of arbitrarily-complex interactions between combinations of student-level predictor variables and intervention outcome, defined as the improvement in grade point average (GPA) during the transition to high school. We utilized two separate machine learning models: one to control for complex relationships between 51 student-level predictors and GPA, and one to predict the change in GPA due to the intervention. We analyzed the trained models to discover which features influenced model predictions most, finding that prior academic achievement, blocked navigations (attempting to navigate through the intervention software too quickly), self-reported reasons for learning, and race/ethnicity were the most important predictors in the model for predicting intervention effectiveness. As in previous research, we found that the intervention was most effective for students with prior low academic achievement. Unique to this study, we found that blocked navigations predicted an intervention effect as low as 0.185 GPA points (on a 0-4 scale) less than the mean. This was a notable negative prediction given that the mean intervention effect in our sample was just 0.026 GPA points, though few students (4.4%) experienced a substantial number of blocked navigation events. We also found that some minoritized students were predicted to benefit less (or even not at all) from the intervention.

description: R is a robust open-source programming language mainly used for statistical computing . Many areas of statistical research are experiencing rapid growth in the size of data sets. Methodological advances drive increased use of simulations. A common approach is to use parallel/concurrent computing. This paper presents an overview of techniques for parallel computing with R on ACI (a PSU Infrastructure) and benchmark it with C/C++. We review the scalabilty concern of R, and look at the simplicity of using R as a primary language in Coding for HPC. We will look at the various R packages for HPC like Rmpi, Rcpp, snow and snowfall. We utilize a series of algorithms to benchmark and will illustrate each benchmark with a representative graph for ease of understanding. The paper concludes with a better understanding of which language to use when in high performance computing .

description: The filamentary structure of the early universe has until now only been seen in numerical simulations. Despite this lack of direct observational evidence, the prediction of early filamentary structure formation in a Cold Dark Matter dominated universe has become a paradigm for our understanding of galaxy assembly at high redshifts. Clearly observational confirmation is required. Lyman Break galaxies are too rare to be used as tracers of filaments and we argue that to map out filaments in the high z universe, one will need to identify classes of objects fainter than those currently accessible via the Lyman Break technique. Objects selected via their Ly-alpha emission, and/or as DLA absorbers, populate the faintest accessible part of the high redshift galaxy luminosity function, and as such make up good candidates for objects which will map out high redshift filaments. Here we present the first direct detection of a filament (at z=3.04) mapped by those classes of objects. The observations are the deepest yet to have been done in Ly-alpha imaging at high redshift, and they reveal a single string of proto-galaxies spanning about 5 Mpc (20 Mpc comoving). Expanding the cosmological test proposed by Alcock & Paczynski (1979), we outline how observations of this type can be used to determine Omega_Lambda at z=3.

description: Deep observations have detected extended Lya emission nebulae surrounding tens of quasars at redshift 2–6. However, the metallicity of such extended halos is still poorly understood. We perform a detailed analysis on a large sample of quasars at z~3 based on MUSE-VLT data. We find clear evidence of extended emission of CIV1549, HeII1640 and CIII]1909 out to a radius of ~45 kpc. We infer that the average metallicity of the CGM gas within the central 30–50 kpc is ~0.5 solar, or even higher. We also find evidence of a component of the Lya halos, which has much weaker metal emission lines relative to Lya. We suggest that the high metallicity of the CGM within the central 30–50 kpc is associated with chemical pre-enrichment by past quasar-driven outflows and that there is a more extended metal-poor component of the CGM that is likely associated with near-pristine gas accreted from the IGM. Our results are in good agreement with the expectations of the FABLE zoom-in cosmological simulations.

description: One of the criteria to evaluate management ability of a company to gain return is assets return rate, with regard to existing resources. Management is expected to use the current assets so that the maximum return is gained. The present study aims at investigating assets return rate impact on stock prices of the companies accepted in Tehran stock exchange. In this research, assets return rate is considered as independent variable, and stock price as dependent variable, and company size, company age, and beta coefficient as control variables from 2001 to 2010. Research method is correlation in terms of hypothesis testing, and through multi-variable regression statistic analysis has been done. The research findings indicate strong impact and relationship between independent and dependent variables, and the research hypothesis has been accepted.

description: In many voice biometrics applications there is a requirement to preserve privacy, not least because of the recently enforced General Data Protection Regulation (GDPR). Though progress in bringing privacy preservation to voice biometrics is lagging behind developments in other biometrics communities, recent years have seen rapid progress, with secure computation mechanisms such as homomorphic encryption being applied successfully to speaker recognition. Even so, the computational overhead incurred by processing speech data in the encrypted domain is substantial. While still tolerable for single biometric comparisons, most state-of-the-art systems perform some form of cohort-based score normalisation, requiring many thousands of biometric comparisons. The computational overhead is then prohibitive, meaning that one must accept either degraded performance (no score normalisation) or potential for privacy violations. This paper proposes the first computationally feasible approach to privacy-preserving cohort score normalisation. Our solution is a cohort pruning scheme based on secure multi-party computation which enables privacy-preserving score normalisation using probabilistic linear discriminant analysis (PLDA) comparisons. The solution operates upon binary voice representations. While the binarisation is lossy in biometric rank-1 performance, it supports computationally-feasible biometric rank-n comparisons in the encrypted domain.

As a corollary, we exhibit a genuine real symplectic phenomenon in terms of involutions, namely that the Chekanov torus $\mathbb{T}_{\text{Chek}}$ in $S^2\times S^2$, which is a monotone Lagrangian torus not Hamiltonian isotopic to the Clifford torus $\mathbb{T}_{\text{Clif}}$, can be seen as the fixed point set of a smooth involution, but not of an antisymplectic involution.

description: A wide range of observational and theoretical arguments suggest that the universe experienced a period of heating and metal enrichment, most likely from starbursting dwarf galaxies. Using a hydrodynamic simulation we have conducted a uniquely detailed theoretical investigation of this epoch at the end of the cosmological ``dark ages''. Outflows strip baryons from pre-viralized halos with total masses $\lesssim10{}^{10}$ M${}_\odot$, reducing their number density and the overall star formation rate, while pushing these quantities toward their observed values. We show that the metallicity of $\lesssim10{}^{10}$ M${}_\odot$ objects increases with size, but with a large scatter, reproducing the metallicity-luminosity relation of dwarf galaxies. Galaxies $\gtrsim10{}^{10}$ M${}_\odot$ form with a roughly constant initial metallicity of 10% solar, explaining the observed lack of metal-poor disk stars in these objects. Outflows enrich roughly 20% of the simulation volume, yielding a mean metallicity of 0.3% solar, in agreement with observations of CIV in QSO absorption-line systems.

description: The design of safety-critical systems is often an incredibly difficult and arduous process due to the rising complexity of these systems leveraged against the need for these systems to have a high level of reliability and correctness. Safety-Critical systems cover a wide variety of applications, including medical devices (such as pacemakers and insulin pumps), navigation applications (such as for flight systems or autonomous vehicles) and space applications (fuel injection systems for rockets). However, although the design of a safety-critical system can cover many domains, different safety-critical systems often share the same characteristics. For example, often, a safety-critical system requires a high level of dependability. One aspect of guaranteeing this dependability is by enforcing that the system is capable of being quantitatively verified and validated. Thus, a developer can measure whether the system is free of defects. The development of safety-critical systems is often an exercise of trade-offs. The more complex a system, the harder it is to reason about and ensure correctness. When developing safety-critical systems, the concept of simplicity is often employed so that the system remains as simple as possible, and is therefore more comprehensible and lends itself to easier testing. However, current trends reveal that there is a growing need for more complex safety-critical systems. As such, safety-critical systems are becoming more complex not less. In an environment where it is not possible to create simple systems, the developers of such systems are left with less confidence that the systems they build will operate as intended. The main contribution of this thesis is an attempt to tackle this issue of designing complex safety-critical systems through methods and techniques that make the design of such systems possible. This thesis opts to tackle the rising complexity of safety-critical systems by leveraging the concepts of decomposability, composability, and modularisation. That is, this thesis presents new techniques to isolate the behaviour of sub-systems that make it possible to comprehend each sub-system independently without considering the system as a whole. These new techniques facilitate modularisation and composability by defining clear communication methods that can be leveraged to create a system comprised of multiple modules that communicate, whilst also maintaining decomposition by safeguarding the internal behaviour of modules from the influence of external modules. A thorough evaluation of these methods and techniques provides the software engineer with the tools necessary to assess trade-offs and develop complex safety-critical systems.

description: Motor insurance constitutes the most popular type of insurance products purchased in Poland and consequently the largest part of non-life insurance sector. In this paper the selected results of the questionnaire survey concerning attitudes and choices of the motor insurance buyers on the Polish market are presented. First, the current situation on the Polish motor insurance market is discussed. Next, the scope of the motor insurance held by respondents, their forms and used distribution channels are analysed. The stress is put on the level of the customers` loyalty to the current insurer, as well as the factors influencing the choice of a specific insurance company and its offer. Finally, the analysis concerning the statistical interdependencies between selected characteristics of the respondents is carried out. The conducted research can be useful for the insurance companies, interested in improving their motor insurance offer, as well as the insurance intermediaries serving individual customers.

description: Solar cells with a heterojunction between colloidal CuInS$_2$ and ZnO nanocrystals are an innovative concept in solution-processed photovoltaics, but the conversion efficiency cannot compete yet with devices employing lead chalcogenide quantum dots. Here, we present a detailed study on the charge collection in CuInS$_2$/ZnO solar cells. An inverted device architecture was utilized, in which the ZnO played an additional role as optical spacer layer. Variations of the ZnO thickness were exploited to create different charge generation profiles within the light-harvesting CuInS$_2$ layer, which strongly affected both the external and internal quantum efficiency. By the reconstruction of these experimental findings with the help of a purely optical model, we were able to draw conclusions on the spatial dependency of the charge collection probability. We provide evidence that only carriers generated within a narrow zone of circa 40 nm near the CuInS$_2$/ZnO interface contribute to the external photocurrent. The remaining part of the absorber can be considered as "dead zone" for charge collection, which reasonably explains the limited device performance and indicates a direction for future research. From the methodical point of view, the optical modeling approach developed in the present work has the advantage that no electrical input parameters are required and is believed to be easily transferable to other material systems.

Year: 2016

description: Transformation is the creation and change of a whole new form, function or structure. To transform is to create something new that has never existed before and could not be predicted from the past. The effort put in place by public administrators in the transforming process is a catalyst for growth, national renewal and a lasting source of comparative advantage, which will become very significant and paramount to the state.  As a state, Nigeria has failed to meet the basic human needs of its population; it lacks transparent and accountable political institutions and it has not produced sustainable or equitable economic growth.  The overall goal of public administrators amongst others’ is to guarantee the wellbeing and productivity of the people, by promoting the eradication of negative vices like extreme hunger and poverty.  While efforts are geared towards promoting sustainable housing, access to micro-credit, gender equality, transparency and accountability in budget implementation etc.  Against this backdrop this paper is set to examine innovations and best practices by Nigerian public administrators in a democratic society towards transformation process, as it recognizes the variety of operational and strategic challenges, which policymakers ought to address, in order to achieve ultimate goal and raise the quality of service delivery to the citizens.  The study submits that in spite of daunting challenges such as lack of political and bureaucratic commitments, some progress has been made by the public administrators towards achieving sustainable democratic environment and repositioning administration for higher levels of efficiency and effectiveness in service delivery. Accordingly, recommendations were made to enable administrators fare better in the discharge of their duties to the citizens and to the society in general.

description: We report optical, infrared, and X-ray light curves for the outburst, in 2000, of the black hole candidate XTE J1550-564. We find that the start of the outburst in the H and V bands precedes that seen in the RXTE All Sky Monitor by 11.5 +/- 0.9 and 8.8 +/- 0.6 days, respectively; a similar delay has been observed in two other systems. About 50 days after the primary maxima in the VIH light curves, we find secondary maxima, most prominently in H. This secondary peak is absent in the X-ray light curve, but coincides with a transition to the low/hard state. We suggest that this secondary peak may be due to non-thermal emission associated with the formation of a jet.

description: Online market is fast expending as more consumers are increasingly shopping online and businesses solidifying their presence online. This paper examines the most preferred (primary or most frequent) market venues that online shoppers use when purchasing locally/regionally grown fresh produce. The target population consists of consumers who made at least two any online purchases within six months prior to participating in this study; hereby referred to as “online shoppers”. The sample consists of 1,205 randomly selected online shoppers residing within the South region of the U.S. Data collection was done using Qualtrics actively managed market research panels and social media such as Facebook, and Twitter. Results indicate that grocery stores are the most preferred market venue online shoppers use to purchase locally/regionally grown fresh produce. The relative probability associated with this situation is 44 percent. Farmers’ markets are the second most frequent market venues with a relative likelihood of 33 percent. The third market venue is on-farm (road stands, you-pick-your own, and agritourism) and the CSA program with relative probability of 7 percent. Online market is currently the fourth most frequent with a relative likelihood of 5 percent. 11 percent of the online shoppers have no particular market venue they consider as primary. This analysis is significant to fresh produce growers and marketers within local food movement because it provides analysis of the most preferred market venues among the increasingly common type of consumers. Results suggest new marketing strategies to conveniently make fresh produce accessible among online shoppers. Furthermore, this study sets a basis for future analyses that will be interested in trucking changes in the preferred market venues for local/regional fresh produce among online shoppers.

description: Shubnikov de Haas resistance oscillations of highly mobile two dimensional helical electrons propagating on a conducting surface of strained HgTe 3D topological insulator are studied in magnetic fields B tilted by angle $θ$ from the normal to the conducting layer. Strong decrease of oscillation amplitude A is observed with the tilt: $A \sim \exp(-ξ/cos(θ))$, where $ξ$ is a constant. Evolution of the oscillations with temperature T shows that the parameter $ξ$ contains two terms: $ξ=ξ_1+ξ_2 T$. The temperature independent term, $ξ_1$, describes reduction of electron mean free path in magnetic field B pointing toward suppression of the topological protection of the electron states against impurity scattering. The temperature dependent term, $ξ_2 T$, indicates increase of the reciprocal velocity of 2D helical electrons suggesting modification of the electron spectrum in magnetic fields.

description: Long range environmental transport is known to facilitate the poleward move of persistent and semi volatile agrochemicals. Their bioaccumulation and biomagnification along Antarctic food web have been evidenced including detection in the Antarctic keystone species, Antarctic krill, as well as in second order consumers such as southern hemisphere humpback whales (SHHW). SHHW are one of the six baleen whale species that feed in the Southern Ocean and undertake one of the longest mammalian migrations. During migration, SHHW undergo voluntary fasting, a remarkable adaptation that allows them to convert their lipid stores into energy, which inadvertently results in mobilisation of lipophilic chemical burdens from liberated fat stores. The biological impact of elevated chemical exposure could have significant effects on metabolism, reproduction, and immune functions. The process of converting lipids to energy is regulated by mitochondria. Any mitochondrial abnormalities therefore carry the potential to interrupt bioenergetics. Despite this, the inherent absence of opportunity for controlled study on these large mammals means that our basic understanding of the threats posed by contaminants to the species is incomplete. The need for species-specific chemical risk data has recently led to the cultivation of humpback whale primary and immortalised fibroblasts cell lines, which offer an opportunity for the study of cetacean chemical risk. Before conducting any risk assessment, it is essential to characterise the cell, as this knowledge is a prerequisite for a robust understanding of toxicological mechanisms of action. This thesis aims to generate SHHW species-specific in vitro chemical effect data, through the application of advanced technologies, hereby advancing cetacean ecotoxicology. [...]

description: This paper compares precision farming technology with calendar-based approaches in scheduling fungicide applications to manage tomato late blight disease. Two fungicide scheduling strategies were evaluated: calendar-based strategy and BlightPro decision support system based strategy (DSS-based strategy). Using results from 14 years of computer simulation experiments for 25 locations in the United States, we constructed distributions of net return to all costs excluding fungicide cost and application cost (net return per acre) for the calendar-based and DSS-based strategies at each location. These distributions were then compared using three risk management methods: stochastic dominance, stochastic dominance with respect to a function, and stochastic efficiency with respect to a function. Results show that in terms of disease control, the DSS recommended spray schedule is more effective. Depends on the percentage of tomato yield improvement for DSS, the preferred strategy is different. Average net income over fungicide cost and average risk-adjusted net income for the DSS recommended spray schedule is lower for susceptible cultivars and higher for moderately susceptible cultivars and moderately resistant cultivars with no yield improvement for DSS strategy. The value added by DSS ranges from -$17.69 to $48.33 per acre with no tomato yield improvement for DSS strategy. When there are more than 5% yield improvement, DSS strategy is strong preferred strategy by tomato growers. Our research contributes to the literature by providing a method to evaluate the economic benefit of adopting DSS.

description: The electronic properties of thin metallic films deviate from the corresponding bulk ones when the film thickness is comparable with the wavelength of the electrons at the Fermi level due to quantum size effects (QSE). QSE are expected to affect the film morphology and structure leading to the low temperature (LT) ``electronic growth'' of metals on semiconductors. In particular, layer-by-layer growth of Pb(111) films has been reported for deposition on Ge(001) below 130 K. An extremely flat morphology is preserved throughout deposition from four up to a dozen of monolayers. These flat films are shown to be metastable and to reorganize into large clusters uncovering the first Pb layer, pseudomorphic to the substrate, already at room temperature. Indications of QSE induced structural variations of the growing films have been reported for Pb growth on Ge(001), where the apparent height of the Pb(111) monatomic step was shown to change in an oscillatory fashion by He atom scattering (HAS) during layer-by-layer growth. The extent of the structural QSE has been obtained by a comparison of the HAS data with X-ray diffraction (XRD) and reflectivity experiments. Whereas step height variations as large as 20 % have been measured by HAS reflectivity, the displacement of the atomic planes from their bulk position, as measured by XRD, has been found to mainly affect the topmost Pb layer, but with a lower extent, i.e. the QSE observed by HAS are mainly due to a perpendicular displacement of the topmost layer charge density. The effect of the variable surface relaxation on the surface vibration has been studied by inelastic HAS to measure the acoustic dispersion of the low energy phonons.

description: Figure S2. Microbiome diversity and evenness trajectories. A heatmap with microbiome diversity trajectories at phylum level is displayed in (A), at species level in (B), of microbiome evenness at phylum level in (C), and at species level in (D). Microbiome diversity was calculated using the Shannon index, and evenness using the reciprocal of Simpsonâ s dominance (see patients and methods). Diversity and evenness values are printed in all boxes for each study participant (Patient ID, on y-axis) and day of stool collection (T0 - T3, on x-axis). Treatment period was from T1 to T3. T0 is the sample before antibiotic exposures. Orange heatmaps include patients from the ciprofloxacin cohort, blue heatmaps patients from the cotrimoxazole cohort. The bottom row of the heatmaps presents the mean value of each column, here the sample collection time point. The intensity of the color bar reflects the diversity and evenness values, with a deeper color for higher values. (PDF 1281 kb)
