description: Recent advances in practical quantum computing have led to a variety of cloud-based quantum computing platforms that allow researchers to evaluate their algorithms on noisy intermediate-scale quantum (NISQ) devices. A common property of quantum computers is that they can exhibit instances of true randomness as opposed to pseudo-randomness obtained from classical systems. Investigating the effects of such true quantum randomness in the context of machine learning is appealing, and recent results vaguely suggest that benefits can indeed be achieved from the use of quantum random numbers. To shed some more light on this topic, we empirically study the effects of hardware-biased quantum random numbers on the initialization of artificial neural network weights in numerical experiments. We find no statistically significant difference in comparison with unbiased quantum random numbers as well as biased and unbiased random numbers from a classical pseudo-random number generator. The quantum random numbers for our experiments are obtained from real quantum hardware.

description: The increasing use of the territorial approach in the process of public policy design in Brazil has stimulated a series of studies about this theme. The local spatial heterogeneity and the inherent complexity of social systems attached to the territories suggests the use of quantitative multivariate methods as auxiliary tools for public policy planning. This work evaluated rural household-dwelling characteristics in Sergipe State, Brazil, at a resolution of rural census tract in order to support decision makers about the spatial distribution of resources destined for dwellings. It has been analyzed three regional partitions : municipalities, Territories of Citizenship and Territories of State’s Planning, using demographic census data from 2010. The study has been conducted by using factorial analysis and clustering techniques. Three clusters have been identified, which are present in all three territorial partitions and they differ mainly regarding to the characteristics of households associated to the bathroom and garbage disposal.

description: Much of the recent efforts on salient object detection (SOD) have been devoted to producing accurate saliency maps without being aware of their instance labels. To this end, we propose a new pipeline for end-to-end salient instance segmentation (SIS) that predicts a class-agnostic mask for each detected salient instance. To better use the rich feature hierarchies in deep networks and enhance the side predictions, we propose the regularized dense connections, which attentively promote informative features and suppress non-informative ones from all feature pyramids. A novel multi-level RoIAlign based decoder is introduced to adaptively aggregate multi-level features for better mask predictions. Such strategies can be well-encapsulated into the Mask R-CNN pipeline. Extensive experiments on popular benchmarks demonstrate that our design significantly outperforms existing \sArt competitors by 6.3\% (58.6\% vs. 52.3\%) in terms of the AP metric.The code is available at https://github.com/yuhuan-wu/RDPNet.

description: Corn producers need to find the best alternative to sell the production; selling before harvest, during the harvest, in the future market or store to sell in the off-season period. However, this is not an easy task because the crop is affected by several variables. In this study, we analyzed international and Brazilian corn production data to find out the best strategy of corn commercialization for Mato Grosso do Sul State (Brazil) producers. We considered four variables alltogether: logistics, price, productivity and product availability. The multicriteria analysis was done using the Analytic Hierarchy Process (AHP) using the software Expert Choice © v.11. The results indicated that the best decision for growers in Mato Grosso do Sul is selling the corn production in the offseason. Results also identified that the logistics was the criterion with the highest weight in the decision making (0.467).

description: Bell inequalities are a vital tool to detect the nonlocal correlations, but the construction of them for multipartite systems is still a complicated problem. In this work, inspired via a decomposition of $(n+1)$-partite Bell inequalities into $n$-partite ones, we present a generalized iterative formula to construct nontrivial $(n+1)$-partite ones from the $n$-partite ones. Our iterative formulas recover the well-known Mermin-Ardehali-Belinski{\uı}-Klyshko (MABK) and other families in the literature as special cases. Moreover, a family of ``dual-use'' Bell inequalities is proposed, in the sense that for the generalized Greenberger-Horne-Zeilinger states these inequalities lead to the same quantum violation as the MABK family and, at the same time, the inequalities are able to detect the non-locality in the entire entangled region. Furthermore, we present generalizations of the the I3322 inequality to any $n$-partite case which are still tight, and of the $46$ Śliwa's inequalities to the four-partite tight ones, by applying our iteration method to each inequality and its equivalence class.

subject: F32, F34

description: During 1982 increasing strains have emerged in the financing of external deficits, and important sovereign borrowers, no longer able to meet their debt service commitments, have sought a rescheduling of their foreign debt. At the same time the international banking system has reduced its lending for balance of payments financing. To understand these developments and the policy measures required to maintain international financial stability, the present work examines the effects of the two successive oil shocks on the world economy and assesses the impact of these factors on banks’ balance sheets and operations. The author discusses the functions of banking supervision in promoting the stability of the system and examines the contribution that policy action can make, at the national and world levels, to strengthen the structure of international financing relationships.

description: The work presents a linear model of the private market sector of the economy built out of the main blocks of Keynes with some pieces furnished by Kalecki, Kaldor, and Robinson. The author argues that such model is rich in promise by virtue of its scope and that it strips much of the mystery from econometric models and demonstrates the circumstances in which they are likely to perform well or badly. The consistent relations offer hospitable shelter for the theory of income, employment, price level, and income shares in a succinct design. Pedagogically, the elemental ideas are capable of transmission at an early stage in economic studies. JEL: E12

description: The sugarcane industry is strategic regarding the increasing demand for new sources of energy alternatives to oil and byproducts, given the pressures on the raw material. Due the future scenario that is taking shape, the ethanol produced from the sugarcane has advantages to conquer new markets, but since it has an efficient production and that makes a good use of existing resources. Therefore, the study analyzes the Total Factor Productivity (TFP) and their components for 17 mills in the Center-Southern region in Brazil during the period from 2001 to 2008. The sample is considered significant because the volume of cane crushed represents 11.5% of the total in Brazil. The methodology is based on Coelli et al. (1998), from Data Envelopment Analysis (DEA), using the Malmquist index, which assesses the productivity levels over time, decomposing them into indices that capture variation of the technical efficiency and technological changes. The paper concludes that the sample is composed mostly of followers, ie, the plants do not create and adopt radical innovations. They just follow a set move toward technologies already tested in the market and proven by other plants.

description: Despite numerous changes over the past 20 years, there can be little doubt that the 12 discount houses still constitute the core of money market arrangements in London. They form the London Discount Market Association and they have accounts with the Bank of England, which give them access to the Bank of England as lender of last resort to the banking system. The Bank of England is now attempting to ensure that the discount houses maintain prudent business practices at all times and do not expose themselves excessively to risks that they may not be able to meet if the value of investments falls.The author provides an in-depth review of the recent changes to London’s money market arrangements concluding that on the whole, the new rules are a formalisation of good working practices.

description: Extension approaches and practices have changed enormously during the last decades. At the same time, several authors have pointed out the persistence of traditional, diffusionist approaches in extensionists’ practices as well as in extension institutions. In this research, extension practices implemented in the Argentine Northeastern region are analyzed and compared with institutional and current academic proposals, aiming to draw useful recommendations. In order to do so, 40 interviews with rural extensionists who work in the public system in the provinces of Chaco, Corrientes, Formosa and Misiones were conducted and analyzed. Results show that the interviewees aim their practices at the productive improvement and the strengthening of farmers’ organizations, value implementing demand-driven interventions, and prioritize group approaches. In general terms, the extensionists’ practices are consistent with the National Institute of Agricultural Technology’s proposal and with most of the guidelines provided by the specialized literature. Nonetheless, doubts remain with regards to the real value given to group work, interinstitutional articulation and participation. Likewise, the lack of interest about gender issues and evaluation of extension projects are also cause of concern.

description: For almost forty years, from the decade of the sixties up to the present, many new schools, theories, currents and thoughts have been incorporated into the agribusiness management world, all these established by different authors in their own way and according to their own experience. The valuable contribution of each documental and bibliographic analysis is to understand and assimilate the most important issues in each of them. We can see that our own enterprises organized the Mexican way, can be subject to up-dating and continuous improvement in their internal structure. All these statements are valid, as long as we have the capacity and talent to know how to adapt and adopt them to our own circumstances. Nowadays, the control over these matters belongs to American authors. We need to locate the medullar issue that will allow Mexican enterprises to grow under their own methodology avoiding the effect of other cultures by acquiring foreign techniques or management methods and trying to adopt them immediately without proper examination and previous analysis. The challenge for agribusinesses in Mexico, including agricultural, farming and agribusiness developments, is to gradually change with business maturity management techniques, according to the size and conditions of each enterprise, in order to compete first in the national market and then worldwide. The present applied research essay seeks to develop a synthesis of these concepts and state the experience of how the technique called STRATEGIC AGRIBUSINESS MANAGEMENT PROCESS, PAAE (for its initials in Spanish), has been incorporated in the agribusiness scope. This line of research has been improved for more than three decades in order to be successfully applied in the rural environment.
Infinitesimal rigidity and prestress stability for frameworks in normed spaces

description: A (bar-and-joint) framework is a set of points in a normed space with a set of fixed distance constraints between them. Determining whether a framework is locally rigid - i.e. whether every other suitably close framework with the same distance constraints is an isometric copy - is NP-hard when the normed space has dimension 2 or greater. We can reduce the complexity by instead considering derivatives of the constraints, which linearises the problem. By applying methods from non-smooth analysis, we shall strengthen previous sufficient conditions for framework rigidity that utilise first-order derivatives. We shall also introduce the notions of prestress stability and second-order rigidity to the topic of normed space rigidity, two weaker sufficient conditions for framework rigidity previously only considered for Euclidean spaces.

description: The work examines Monetary Trends, the third in a series of volumes published over the last twenty years by Milton Friedman and Anna Schwartz under the auspices of the NBER. Due to the limited scope of the article, the author pivots the discussion on two questions which appear to be crucial and which Friedman’s previous works have not succeeded in dissipating legitimate doubts. The first is Friedman’s view regarding the absence of theoretical divisions between “good” monetarists and Keynesians, and the second is the ability of tests to play a crucial part in the choice between conflicting theories. The author deals with the presentation and discussion of the core of the theory and of the additional propositions before examining if their predictions conform to empirical evidence. JEL: B31, E42

description: Areas of rangelands are deteriorated, show low production and need range seeding for restoration. However, seed availability of forage species is limited as a result seed is imported and expensive. We compare seed cost of two forage species harvested during 2012 and 2013 in central Sonora, Mexico with seed prices of regional seed dealers and with several seed companies in USA. Seed production and quality was evaluated based on germination, purity and viability (%). Production costs, handling and transportation as well as sanitary control tests and importation expenses were evaluated. Results show that the total cost per kilogram of seed (PLS) basis averaged $3,845.81 and $265.84 for zámota and mesquite on local harvested seed; $5,000.00 and $450.00 for zámota and mesquite on regionally obtained seed and $16,579.10 and $5,954.80 for zámota and mesquite imported seed. Quality of seed harvested locally is similar to seed bought regionally and to imported seed, which results 1 to 56 times more expensive as compared to local seed. We conclude that seed quantity and quality of trees produced on rangelands during good rainfall years is adequate for range rehabilitation. High profits by harvesting and selling local seed may result in an important complementary income source to increase utilities of low income people. Besides increasing rancher’s income, this allows to increase temporal employment in the rural areas.

Large Extra Dimensions and the Minimal Length

Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Large extra dimensions lower the Planck scale to values soon accessible. Motivated by String Theory, the models of large extra dimensions predict a vast number of new effects in the energy range of the lowered Planck scale, among them the production of TeV-mass black holes and gravitons. But not only is the Planck scale the energy scale at which effects of modified gravity become important. String Theory as well as non-commutative quantum mechanics suggest that the Planck length acts as a minimal length in nature, providing a natural ultraviolet cutoff and a limit to the possible resolution of spacetime. Within the extra dimensional scenario, the minimal length effects thus become important in the same energy range in which the effective extra dimensional models predict new physics. We examine a model which includes the minimal length into the extra dimensional extension of the Standard Model.

Landscape analysis of distribution and demographic consequences in a brood parasite-host system
Creators: name: Jewell, Kelly Jean
Publisher: name: University of British Columbia
Year: 2011

description: Source-sink dynamics may occur where variation in predation or parasitism is sufficient to cause spatial variation in population performance. Brood parasitic brownheaded cowbirds Molothrus ater locally reduce host reproductive success, but little is known about their regional effects on demography. I aimed to predict, using detailed empirical data, the effect of cowbirds on the spatial dynamics of a preferred host, the song sparrow Melospiza melodia. My objectives were to: (1) predict the distributions of parasite and host based on landscape features; (2) predict parasitism rates from cowbird occurrence and relate this to sparrow fecundity; and (3) map expected population growth rates (λ) for song sparrows given parasitism, testing if spatial refuges from parasitism exist. I used logistic regression to predict cowbird occurrence by analyzing >500 avian point counts in the Southern Gulf Islands (SGI), BC. I also evaluated alternate hypotheses for landscape features thought to influence cowbird distribution elsewhere. Cowbird occurrence in the SGI was best predicted by proximity to potential feeding areas and landcover. The best logistic model included landcover, cattle, and distance to urban and agriculture. Autologistic regression improved model performance, and models using widely available data performed only slightly worse than those including all data. All models of cowbird occurrence compared favorably with parasitism rates observed in 12 populations studied from 1 -8 years. To estimate the regional effect of cowbirds, I employed data from 10 islands studied from 2-8 years to estimate λ in song sparrow populations subject to parasitism. Predicted growth rates were strongly influenced by cowbird distribution and land use, and were consistent with independent estimates of local population trend and findings relating parasitism rates to landscape features elsewhere in their range. My results suggest that the ratio of source to sink populations within a study region will depend on land use patterns, their effect on cowbird distribution, and the influence of parasitism on host reproduction. I use my results to suggest improvements for future habitat modelling studies, management to limit cowbird distribution and identify host refuges, and an approach to estimate the regional effect of enemies on the spatial population demography of species of conservation concern.
The Hungarian economic reform, 1968-82

description: The present work begins by briefly describing the principal features of the comprehensive economic reform that was introduced in Hungary in 1968, before assessing economic performance under the reform and tendencies towards recentralisation. The economic effects of the policies applied is then analysed. The further reforms of 1980-81 are then evaluated, followed by agriculture and the “Second Economy”. The author concludes that Hungary has successfully established an economic system which combines the large-scale socialist sector, co-operatives, and small-scale private activities in a flexible manner, possibly explaining the availability of a wide range of consumer goods and services that is unique in the CMEA area.

description: Serious concern about the economic disparities between the regions of European States predates the formulations of European Community regional policy, and even the foundation of the Community itself. The present paper reviews the evolution of European regional problems in the growing Community and within a changing world economy. The authors examine the typology of regions which has emerged from many years of discussion, and suggest some major adaptations in the concepts, policies and priorities of European regional policy today. They conclude that Community Regional Policy in its established form is incapable of managing widespread de-industrialization, and should rather function as an instrument of solidarity, focusing on the regions of greatest need.

description: Feature selection techniques are essential for high-dimensional data analysis. In the last two decades, their popularity has been fuelled by the increasing availability of high-throughput biomolecular data where high-dimensionality is a common data property. Recent advances in biotechnologies enable global profiling of various molecular and cellular features at single-cell resolution, resulting in large-scale datasets with increased complexity. These technological developments have led to a resurgence in feature selection research and application in the single-cell field. Here, we revisit feature selection techniques and summarise recent developments. We review their versatile application to a range of single-cell data types including those generated from traditional cytometry and imaging technologies and the latest array of single-cell omics technologies. We highlight some of the challenges and future directions on which feature selection could have a significant impact. Finally, we consider the scalability and make general recommendations on the utility of each type of feature selection method. We hope this review serves as a reference point to stimulate future research and application of feature selection in the single-cell era.

description: Most platforms, including Reddit, face a dilemma when applying interventions such as subreddit bans to toxic communities -- do they risk angering their user base by proactively enforcing stricter controls on discourse or do they defer interventions at the risk of eventually triggering negative media reactions which might impact their advertising revenue? In this paper, we analyze Reddit's previous administrative interventions to understand one aspect of this dilemma: the relationship between the media and administrative interventions. More specifically, we make two primary contributions. First, using a mediation analysis framework, we find evidence that Reddit's interventions for violating their content policy for toxic content occur because of media pressure. Second, using interrupted time series analysis, we show that media attention on communities with toxic content only increases the problematic behavior associated with that community (both within the community itself and across the platform). However, we find no significant difference in the impact of administrative interventions on subreddits with and without media pressure. Taken all together, this study provides evidence of a media-driven moderation strategy at Reddit and also suggests that such a strategy may not have a significantly different impact than a more proactive strategy.

description: Hyperledger Fabric is a popular open-source project for deploying permissioned blockchains. Many performance characteristics of the latest Hyperledger Fabric, such as performance characteristics of each phase, the impacts of ordering services, and bottleneck and scalability, are still not well understood due to the performance complexity of distributed systems. We conducted a thorough performance evaluation on the first long term support release of Hyperledger Fabric. We studied the performance characteristics of each phase, including execute, order, and the validate phase, according to Hyperledger Fabric new execute-order-validate architecture. We also studied the ordering services, including Solo, Kafka, and Raft. Our experimental results showed some findings as follows. 1) The execution phase exhibited a good scalability under the OR endorsement policy but not with the AND endorsement policy. 2) We were not able to find a significant performance difference between the three ordering services. 3) The validate phase was likely to be the system bottleneck due to the low validation speed of chaincode. Overall, our work helps to understand and improve Hyperledger Fabric.

description: This study explores the effect of remittances on human capital development in terms of educational attainment on a global perspectives using GLS modeling. Data from different valid international sources are used in the analyses. Furthermore, it investigates the relationship of remittances with human capital development by region, gender, democracy and financial development. The results reveal significant positive effects of remittances on the changes in average schooling years and secondary enrollment rate in the developing countries. There are regional, genders and financial level variations in human capital development due to remittances flow. Finally, some important policy recommendations have been suggested.

subject: E43, E52

description: The control of the economy is examined in terms of the relationships between instruments and targets. The endogeneity of the budget deficit is analysed, exploring 'reflation' as a possible solution, and it is shown that monetarism has changed people's response patterns. The mechanical approach to economic management, and particularly inflation, is rejected in favour of political solutions and long-term planning. JEL: E43, E52

description: We report a systematic study of high magnetic field specific heat and resistivity in single crystals of CeCoIn_5 for the field oriented in the basal plane (H//ab) of this tetragonal heavy fermion superconductor. We observe a divergent electronic specific heat as well as an enhanced A coefficient of the T^{2} law in resistivity at the lowest temperatures, as the field approaches the upper critical field of the superconducting transition. Together with the results for field along the tetragonal axis (H//c), the emergent picture is that of a magnetic field tuned quantum critical point which exists in the vicinity of the superconducting H_{c2} despite a variation of a factor of 2.4 in H_{c2} for different field orientations. This suggests an underlying physical reason exists for the superconducting H_{c2} to coincide with the quantum critical field. Moreover, we show that the recovery of a Fermi Liquid ground state with increasing magnetic field is more gradual, meaning that the fluctuations responsible for the observed quantum critical phenomena are more robust with respect to magnetic field, when the magnetic field is applied in-plane. Together with the close proximity of the quantum critical point and H_{c2} in CeCoIn_5 for both field orientation, the anisotropy in the recovery of the Fermi liquid state might constitute an important piece of information in identifying the nature of the fluctuations that become critical.

description: Reddit has found its communities playing a prominent role in originating and propagating problematic socio-political discourse. Reddit administrators have generally struggled to prevent or contain such discourse for several reasons including: (1) the inability for a handful of human administrators to track and react to millions of posts and comments per day and (2) fear of backlash as a consequence of administrative decisions to ban or quarantine hateful communities. Consequently, administrative actions (community bans and quarantines) are often taken only when problematic discourse within a community spills over into the real world with serious consequences. In this paper, we investigate the feasibility of deploying tools to proactively identify problematic communities on Reddit. Proactive identification strategies show promise for three reasons: (1) they have potential to reduce the manual efforts required to track communities for problematic content, (2) they give administrators a scientific rationale to back their decisions and interventions, and (3) they facilitate early and more nuanced interventions (than banning or quarantining) to mitigate problematic discourse.

description: We present new phase-resolved H and K-band spectroscopy of the ultra-short period magnetic cataclysmic variable EF Eri in its current, prolonged ``low'' state obtained using NIRI on Gemini-North, and NIRSPEC on Keck II. These new data show that the H-band spectrum of EF Eri appears to be dominated by cyclotron emission during the entire orbital cycle. The {\it K}-band spectrum of EF Eri is likewise dominated by cyclotron emission during most of an orbital period, but near binary phase 0.0, the secondary star spectrum may be visible. We conclude that strong, and highly variable cyclotron emission is responsible for the photometric variation previously reported for EF Eri. The nature of this cyclotron emission is complex: the H-band spectra show that the dominant cyclotron harmonic at phase 0.5 peaks at 1.65 $μ$m, but at phase 0.0, the harmonic peaks near 1.72 $μ$m. At phase 0.5, there is another cyclotron feature present that peaks in between the H and K bands (near 1.93 $μ$m), but at phase 0.0, no such feature is present. These data suggest that cyclotron emission from both poles is occurring.
