description: For a fixed $b\in \mathbb{N}=\{1,2,3,\dots\}$, Goins et al. \cite{Harris} defined the concept of $b$-visibility for a lattice point $(r,s)$ in $L=\mathbb{N}\times \mathbb{N}$ which states that $(r,s)$ is $b$-visible from the origin if it lies on the graph of $f(x)=ax^b$, for some positive $a\in \mathbb{Q}$, and no other lattice point in $L$ lies on this graph between $(0,0)$ and $(r,s)$. Furthermore, to study the density of $b$-visible points in $L$ Goins et al. defined a generalization of greatest common divisor, denoted by $\gcd_b$, and proved that the proportion of $b$-visible lattice points in $L$ is given by $1/ζ(b+1)$, where $ζ(s)$ is the Riemann zeta function. In this paper we study the mean values of arithmetic functions $Λ:L\to \mathbb{ C}$ defined using $\gcd_b$ and recover the main result of \cite{Harris} as a consequence of the more general results of this paper. We also investigate a generalization of a result in \cite{Harris} that asserts that there are arbitrarily large rectangular arrangements of $b$-visible points in the lattice $L$ for a fixed $b$, more specifically, we give necessary and sufficient conditions for an arbitrary rectangular arrangement containing $b$-visible and $b$-invisible points to be realizable in the lattice $L$. Our result is inspired by the work of Herzog and Stewart \cite{Herzog} who proved this in the case $b=1$.

description: In this paper, we propose to augment image-based place recognition with structural cues. Specifically, these structural cues are obtained using structure-from-motion, such that no additional sensors are needed for place recognition. This is achieved by augmenting the 2D convolutional neural network (CNN) typically used for image-based place recognition with a 3D CNN that takes as input a voxel grid derived from the structure-from-motion point cloud. We evaluate different methods for fusing the 2D and 3D features and obtain best performance with global average pooling and simple concatenation. On the Oxford RobotCar dataset, the resulting descriptor exhibits superior recognition performance compared to descriptors extracted from only one of the input modalities, including state-of-the-art image-based descriptors. Especially at low descriptor dimensionalities, we outperform state-of-the-art descriptors by up to 90%.

An investigation into the impact of the switch to liquid sugar

Publisher: name: The University of British Columbia
Year: 2014

description: Over the past year, UBC Food Services has been making a switch from the use of raw sugar in paper sachets to liquid sugar. This has been done to reduce the environmental impact of sugar. It has been noticed that although the paper sachets used to store sugar are recyclable, they are not recycled by customers very often. This has a large impact on the environment, and the switch to liquid sugar was proposed to reduce this impact. To assess the impact of the switch to liquid sugar, our team conducted a triple bottom line analysis. This was done by doing primary as well as secondary research. Our primary research consisted of several in depth interviews with UBC Food Service staff, as well as customers at UBC Food Service locations. We discovered that while UBC Food Service staff was trained to recycle liquid sugar bottles, and waste from these bottles was very little compared to waste from paper sachets. We discovered that while there was some social inertia related to this switch, most customers were happy with the switch after being provided some training and education. In fact, by conducting a social experiment, we discovered that more than 60% of the customers at Neville’s cafe (a UBC Food Service location) preferred liquid sugar after just 2.5 months of training. We also noticed that environmentally conscious customers applauded UBC for the switch, and were in favor of UBC pursuing similar endeavors in the future. On doing some secondary research, we discovered that the cost of providing liquid sugar is greater than the cost of providing sugar in paper sachets. However, we noticed that the quantity of liquid sugar used was significantly lower (about 20%) per cup of beverage compared to the quantity of sachet sugar consumed per cup of beverage. This is due to the sweetness of the liquid sugar as well as its ability to dissolve quickly as compared to sachet sugar. While the switch to liquid sugar will increase costs for UBC and cause some initial discomfort amongst customers of UBC Food Service locations, we believe that not only is this switch feasible, but it is very beneficial to society in the long run. It will significantly reduce the ecological footprint of each UBC Food Service location and further UBC’s position as a leader in sustainability.

description: The paper tells the story of a pensioner’s fight against a local mafia of Soviet party and government officials and farm managers in a remote rural locality in the 1950s. To Moscow, he was a whistleblower. To the leaders of his local community, he was a troublemaker. Working together, the local people went to extraordinary lengths to suppress his criticisms. Eventually, Moscow intervened to vindicate him. The story illustrates vividly the political and economic issues that arose when a centralized dictatorship that relied on mass mobilization over a vast territory with sometimes poor communications tried to contain local rent seeking while moving away from mass terror as its chief instrument of control.

description: In this paper, we analyze the cost allocation problem when a group of agents or nodes have to be connected to a source, and where the cost matrix describing the cost of connecting each pair of agents is not necessarily symmetric, thus extending the well-studied problem of minimum cost spanning tree games, where the costs are assumed to be symmetric. The focus is on rules which satisfy axioms representing incentive and fairness properties. We show that while some results are similar, there are also significant differences between the frameworks corresponding to symmetric and asymmetric cost matrices.

description: Using non-trivial mathematical properties of a class of nonlinear evolution equations, we obtain the universal terms in the asymptotic expansion in rapidity of the saturation scale and of the unintegrated gluon density from the Balitsky-Kovchegov equation. These terms are independent of the initial conditions and of the details of the equation. The last subasymptotic terms are new results and complete the list of all possible universal contributions. Universality is interpreted in a general qualitative picture of high energy scattering, in which a scattering process corresponds to a tree structure probed by a given source.

description: Some studies on child labor have shown that, at the level of the household, greater land wealth leads to higher child labor, thereby casting doubt on the hypothesis that child labor is caused by poverty. This paper argues that the missing ingredient may be an explicit modeling of the labor market. We develop a simple model which suggests the possibility of an inverted-U relationship between land holdings and child labor. Using a unique data set that has child labor hours it is found that, controlling for child, household and village characteristics, the turning point beyond which more land leads to a decline in child labor occurs around 4 acres of land per household.

Relativistic cross sections of mass stripping and tidal disruption of a star by a super-massive rotating black hole

Publisher: name: arXiv

description: [abbreviated] We consider the problem of tidal disruption of a star by a super-massive Kerr black hole. Using a numerically fast Lagrangian model of the tidally disrupted star we survey the parameter space of the problem and find the regions in the parameter space where the total disruption of the star or a partial mass loss take place as a result of fly-by around the black hole. Our treatment is based on General Relativity, and we consider the range of the black hole masses where the tidal disruption competes with the relativistic effect of direct capture of the star by the black hole. We find that our results can be represented on the plane of specific orbital angular momenta of the star $(j_θ, j_ϕ)$. We calculate the contours of a given mass loss of the star on this plane, referred to as the tidal cross sections, for a given black hole mass $M$, rotational parameter $a$ and inclination of the trajectory of the star with respect to the black hole equatorial plane. It is shown that the tidal cross sections can be approximated as circles symmetric above the axis $j_ϕ=0$, and shifted with respect to the origin of the coordinates in direction of negative $j_θ$. The radii and shifts of these circles are obtained numerically for the black hole masses in the range $5\cdot 10^{5}M_{\odot}-10^{9}M_{\odot}$ and different values of $a$. It is shown that when $a=0$ the tidal disruption takes place for $M < 5\cdot 10^{7}M_{\odot}$ and when $a\approx 1$ the tidal disruption is possible for $M < 10^{9}M_{\odot}$.

description: We examine the modulational and parametric instabilities arising in a non-autonomous, discrete nonlinear Schr{ö}dinger equation setting. The principal motivation for our study stems from the dynamics of Bose-Einstein condensates trapped in a deep optical lattice. We find that under periodic variations of the heights of the interwell barriers (or equivalently of the scattering length), additionally to the modulational instability, a window of parametric instability becomes available to the system. We explore this instability through multiple-scale analysis and identify it numerically. Its principal dynamical characteristic is that, typically, it develops over much larger times than the modulational instability, a feature that is qualitatively justified by comparison of the corresponding instability growth rates.

description: The magnetic fields of interplanetary coronal mass ejections (ICMEs), which originate close to the Sun in the form of a flux rope, determine their geoeffectiveness. Therefore, robust flux rope-based models of CMEs are required to perform magnetohydrodynamic (MHD) simulations aimed at space weather predictions. We propose a modified spheromak model and demonstrate its applicability to CME simulations. In this model, such properties of a simulated CME as the poloidal and toroidal magnetic fluxes, and the helicity sign can be controlled with a set of input parameters. We propose a robust technique for introducing CMEs with an appropriate speed into a background, MHD solution describing the solar wind in the inner heliosphere. Through a parametric study, we find that the speed of a CME is much more dependent on its poloidal flux than on the toroidal flux. We also show that the CME speed increases with its total energy, giving us control over its initial speed. We further demonstrate the applicability of this model to simulations of CME-CME collisions. Finally, we use this model to simulate the 12 July 2012 CME and compare the plasma properties at 1 AU with observations. The predicted CME properties agree reasonably with observational data.

description: Journalists and others have asked me whether the favourable RAE 2008 results for UK economics are believable. This is a fair question. It also opens up a broader and more important one: how can we design a bibliometric method to assess the quality (rather than merely quantity) of a nation’s science? To try to address this, I examine objective data on the world’s most influential economics articles. I find that the United Kingdom performed reasonably well over the 2001-2008 period. Of 450 genuinely world-leading journal articles, the UK produced 10% of them -- and was the source of the most-cited article in each of the Journal of Econometrics, the International Economic Review, the Journal of Public Economics, and the Rand Journal of Economics, and of the second most-cited article in the Journal of Health Economics. Interestingly, more than a quarter of these world-leading UK articles came from outside the best-known half-dozen departments. Thus the modern emphasis on ‘top’ departments and the idea that funding should be concentrated in a few places may be mistaken. Pluralism may help to foster iconoclastic ideas.

description: In this paper we review the theoretical issues involved in the direct detection of supersymmetric (SUSY) dark matter. After a brief discussion of the allowed SYSY parameter space we focus on the determination of the traditional neutralino detection rates, in experiments which measure the energy of the recoiling nucleus, such as the coherent and spin induced rates and the dependence of the rate on the motion of the Earth (modulation effect). Then we examine the novel features appearing in directional experiments, which detect the recoiling nucleus in a given direction. Next we estimate the branching ratios for transitions to accessible excited nuclear levels. Finally we comment on the event rates leading to the atom ionization and subsequent detection of the outgoing electrons.

description: The magnetic moment of an electron gas on the surface of constant negative curvature is investigated. It is shown that the surface curvature leads to the appearance of the region of the monotonic dependence $M(B)$ at low magnetic fields. At high magnetic fields, the dependence of the magnetic moment on a magnetic field is the oscillating one. The effect of the surface curvature is to increase the region of the monotonic dependence of the magnetic moment and to break the periodicity of oscillations of the magnetic moment as a function of an inverse magnetic field.

description: This paper compares default incentives in competitive sovereign debt markets when leaders can be either democratically elected or dictators. When leaders can be replaced as in democracies, the incentives for repayment are mainly the ego rents from office and the possibility of getting a corrupt leader from replacement. In a dictatorship, on the other hand, the cost of not repaying loans is the permanent loss of reputation and the loss of future access to credit. There is a trade off between repayment and risk sharing. We show, counter-intuitively, that when ego rents are low, and value of reputation to dictators is high, then democracies repay more often and have lower risk premia than dictatorships.

description: The recent literature suggests that Örst announcements of real output growth in the US have predictive power for the future course of the economy. We show that this need not point to a behavioural relationship, whereby agents respond to the announcement, but may instead simply be a by-product of the data revision process. Initial estimates are subsequently subject to a number of rounds of revisions: the nature of these revisions is shown to be key in determining any apparent relationship between Örst announcements and the future course of the economy.

description: We explore the validity of the generalized Bekenstein bound, S <= pi M a. We define the entropy S as the logarithm of the number of states which have energy eigenvalue below M and are localized to a flat space region of width a. If boundary conditions that localize field modes are imposed by fiat, then the bound encounters well-known difficulties with negative Casimir energy and large species number, as well as novel problems arising only in the generalized form. In realistic systems, however, finite-size effects contribute additional energy. We study two different models for estimating such contributions. Our analysis suggests that the bound is both valid and nontrivial if interactions are properly included, so that the entropy S counts the bound states of interacting fields.

description: In [7-9] and [10] the conjecture is presented that almost-commutative geometries, with respect to sensible physical constraints, allow only the standard model of particle physics and electro-strong models as Yang-Mills-Higgs theories. In this publication a counter example will be given. The corresponding almost-commutative geometry leads to a Yang-Mills-Higgs model which consists of the standard model of particle physics and two new fermions of opposite electro-magnetic charge. This is the second Yang-Mills-Higgs model within noncommutative geometry, after the standard model, which could be compatible with experiments. Combined to a hydrogen-like composite particle these new particles provide a novel dark matter candidate.

description: We present multiwavelength photometric and spectroscopic observations of SN 2019ein, a high-velocity Type Ia supernova (SN Ia) discovered in the nearby galaxy NGC 5353 with a two-day nondetection limit. SN 2019ein exhibited some of the highest measured expansion velocities of any SN Ia, with a Si II absorption minimum blueshifted by 24,000 km s$^{-1}$ at 14 days before peak brightness. More unusually, we observed the emission components of the P Cygni profiles to be blueshifted upward of 10,000 km s$^{-1}$ before B-band maximum light. This blueshift, among the highest in a sample of 28 other Type Ia supernovae, is greatest at our earliest spectroscopic epoch and subsequently decreases toward maximum light. We discuss possible progenitor systems and explosion mechanisms that could explain these extreme absorption and emission velocities. Radio observations beginning 14 days before B-band maximum light yield nondetections at the position of SN 2019ein, which rules out symbiotic progenitor systems, most models of fast optically thick accretion winds, and optically thin shells of mass $\lesssim 10^{-6}$ M$_\odot$ at radii $< 100$ AU. Comparing our spectra to models and observations of other high-velocity SNe Ia, we find that SN 2019ein is well fit by a delayed-detonation explosion. We propose that the high emission velocities may be the result of abundance enhancements due to ejecta mixing in an asymmetric explosion, or optical depth effects in the photosphere of the ejecta at early times. These findings may provide evidence for common explosion mechanisms and ejecta geometries among high-velocity SNe Ia.

Within this framework, we derive ordinary differential equations (ODEs) for the time evolution of the amplitude and phase of modulational perturbations. Analyzing the ensuing ODEs, we re-derive the classical modulational instability criterion. The case (relevant to applications in optics and Bose-Einstein condensation) where the coefficients of the equation are time-dependent, is also examined.

description: The methods of obtaining the average spectral shape in a low statistics regime are presented. Different approaches to averaging are extensively tested with simulated spectra, based on the ASCA responses. The issue of binning up the spectrum before fitting is discussed together with the choice of statistic used to model the spectral shape. The best results are obtained with methods in which input data are represented by probability density functions. Application of weights, representing the coverage between the input and output bins, slightly improves the resolution of averaging.

description: This research investigated the utility of using first-person editorial-style stories as a means to lower the occurrence of self-reported risk-taking behaviors such as drunk driving and red-light running in undergraduate college students. This study assessed the frequency of risk-taking behaviors of college students before and after a three-week online intervention. Students were randomized into one of three conditions. Two risktaking treatment groups read and rated stories about a college student that had suffered a severe consequence from either drunk driving or red-light running. A third group received non-driving college stories that involved no health risk. The stories were presented one per week for three weeks through an online research provider. Participants' behavior change was assessed at a pretest and posttest by a modified Risk Involvement and Perception Scale - Revised (RIPS-R; Parsons, Siegel, & Cousins, 1997) that measured the frequency and attitudes toward various risk-taking behaviors. The stories were designed using elements found in recent social comparison literature (Lockwood, 2002) and risk-taking research (Parsons, Siegel & Cousins, 1997). The undergraduate participants were unaware that their behaviors are being inventoried to measure their change over time. Instead, they were under the assumption that their feedback and activities were necessary to develop realistic stories about a typical college student. Two hundred eighteen undergraduate college students participated, with 186 completing the final assessment (85.3%). Data analyses used mixed ANOV As for between and within group changes in risk-taking behavior and attitudes. Significance was not reached for the main effects for either treatment. Reported red light running reduced from 2.61 times within the initial three weeks surveyed at pre-test to 2.19 at post-test within the corresponding treatment group. Little change was found for the drunk driving condition due to low reports of any drinking and driving behavior across all conditions (n=31, 17%). However, correlations were found between many changes in risk-taking behaviors for both treatment conditions. Additionally, perceived risks were found to be a better predictor of the frequency of reported behavior than perceived benefits. These findings contributed additional information for further developing risk-taking interventions and preventative models.

description: The territory of the Central and Eastern European (CEE) countries mostly belongs to the Continental and Pannonian Bio-geographical Regions. Specific and extreme changes in the weather resulting from the very nature of these Regions can be expected in the near future, and adaptation in agriculture and the bioeconomy is a challenge. Furthermore, in many of these countries the current levels of research, innovation, cooperation and lobbying are substantially below the European Union (EU) average, and this research and innovation divide in Europe hinders both the unlocking of excellence in the CEE region and the development of the European Research Area. BioEast is a new strategic research agenda designed to address these challenges. This paper, firstly, introduces the objectives and focus areas of BioEast; secondly recounts the CEE countries’ actions so far; thirdly describes the institutional set-up of BioEast; fourthly summarises the conclusions from the BioEast workshop held in Budapest on 21-22 February 2017; and fifthly shows how BioEast can help to focus the EU’s agricultural research agenda, especially Horizon 2020, the research and innovation framework programme for the period 2014-2020. Five specific topics are proposed: (a) coordination of bioeconomy-related research and innovation activities; (b) response to climate change and socio-economic challenges; (c) a buffer zone against pathogens; (d) freshwater fish production; and (e)integrated biomass production. Finally, some future actions for BioEast are suggested.

description: This paper responds to the ongoing debate on the improvement of the investment support in the CAP after 2020. First, the analysis of the sector performance of the past investment supports is presented, followed by the farm level dynamic counterfactual analysis of policy results. Baseline and three alternative scenarios of distributions between income and investment support are presented as they were agreed and assessed by experts and stakeholders in two focus groups. Apart from the significant effect on the expansion of livestock production, the impacts of the modernization support (M121) on farm performance are ambiguous. Participants of the focus groups will prefer maintaining the income support at the current level while reducing the intervention stimulating farms investment activity arguing by easier adjustment of activities to the actual needs of the business.

description: We study the high density region of QCD within an effective model obtained in the frame of the hopping parameter expansion. The model still acknowledges the sign problem peculiar to non-zero chemical potential, but it permits the development of refined algorithms which ensure a good overlap of the Monte Carlo ensemble with the true one. We review the main features of the model, including the most explicit form of the resumed expansion, and present calculations concerning the dependence of various observables on the chemical potential and on the temperature, in particular of the charge density and the diquark susceptibility, which may be used to characterize the various phases expected at high baryonic density.

description: Among the European Union-funded programmes supporting development, the LEADER approach aims to promote the peculiarities of rural areas through an innovative participatory approach based on the following key words: participation, decentralisation, partnership and devolution of managerial functions to communities. The approach has been running for 20 years and plays a key role in the development of European rural areas; however, it is still a quite new system for East European countries. In this framework, is the LEADER approach the perfect tool to tackle European rural development issues? This paper explores and compares the implementation of the LEADER approach in Bulgaria, comparing it with Apulia region in Italy, through a web survey administrated to Local Action Groups (LAGs): respondents were 10 Bulgarian and 15 Italian LAGs. The surveyed LAGs deal with diverse challenges concerning the adoption of the LEADER approach, partnerships, available resources and, above all, decision power in the local area. The analysis investigates the so-called ‘Leaderability’ faced by the LAGs, focusing on the main role they cover in the local area: the aim is to examine whether the selected LAGs match with the LEADER features. The results show that most of the Bulgarian and Italians cases consider the LAG as a rural development agency by using strategies, resources and partnerships fitting with the model of Leaderability. The implications shed some light on the need to find a clearer identity according to the diverse LEADER ideal types they can shape, such as information diffusion centre or expertise and competence centre with different responsibilities.

description: The European Innovation Partnership for Agricultural Productivity and Sustainability (EIP-Agri) aims to foster the competitiveness and sustainability of the agriculture and forestry sectors. In the 2014-2020 rural development programmes (RDPs), Operational Groups are multi-actor projects aimed at building bridges between different actors, in order to speed up the development of farmer-driven innovative projects. The Managing Authorities of the RDPs have a crucial role in setting the scene for enabling and promoting such innovation processes. The aim of this research is to explore the different policy frameworks adopted by the Italian regions to support cooperation for innovation projects in RDPs in the period 2007-2013. These were analysed against the conceptual background outlined by the European Commission and the international literature on the interactive approach to innovation processes (EC, 2013). The study is supported by the use of a mixed-methods approach, based on desk and on field research, qualitative and quantitative methods. The results of this research illustrate (a) the relevance of well-defined policy and programme setting to enable innovative environments; (b) differentiation of innovative processes according to local agricultural systems; (c) project-driven innovation approaches might not support the capacity development on innovation; (d) the importance of networking instruments – such as national networks – particularly in regionalised MSs; and (e) the importance of appropriate monitoring and evaluation tools and methods to follow innovations and their effects.
Cooperative approaches to targeted implementation of Agri-Environmental Schemes and the establishment of a case study in Hesse, Germany

description: The increasing intensification of agricultural production and the associated simplification of landscape structure is a major threat to biodiversity. The current Agri-Environmental Scheme (AES) funding structure is lacking the incentive for farmers to participate actively in environmental management and achieve greater environmental objectives. The effectiveness of the AES is a heavily debated topic, since it is not always spatially targeted and in some cases does not consider synergies and trade-offs among the objectives. A case study design was developed to assess whether group approaches have higher degrees of achievement in the allocation of suitable priority areas for species conservation in a landscape. From existing national and international agri-environmental group oriented approaches, an agri-environmental and biodiversity concept for a region in Hesse (Germany) was derived. With a case study in Hesse (Germany), the suitability of such a concept should be controlled and it is to be considered what modifications are necessary in order to use group-oriented approaches successfully. The idea behind the case study is not only to coordinate AES bilaterally between the public sector and individual farmers, but also to look at the best way to reward the farmers for their participation. It is more about sharing knowledge on biodiversity issues with farmers, in the hope of encouraging them to cooperate, and to promote a mutual commitment in the area of regional habitat and species protection.
