description: We consider a model of Bose-Einstein condensate of weakly interacting off-shell gravitons in the regime that is far from the quantum critical point. Working in static spherically symmetric setup, recent study has demonstrated that the effective spacetime geometry of this condensate is a gravastar. In this paper we make three generalizations: introducing a composite of two sets of off-shell gravitons with different wavelength to enable richer geometries for the interior and exterior spacetimes, working in $f({\mathcal R})$ gravity, and extending the calculations to higher dimensions. We find that the effective spacetime geometry is again a gravastar, but now with a metric which strongly depends on the modified gravity function $f({\mathcal R})$. This implies that the interior of the gravastar can be de Sitter or anti-de Sitter and the exterior can be Schwarzschild, Schwarzschild-de Sitter, or Schwarzschild-anti-de Sitter, with a condition that the cosmological constant for the exterior must be smaller than the one for the interior. These geometries are determined by the function $f({\mathcal R})$, in contrast to previous works where they were selected by hand. We also presented a new possible value for the size of the gravastar provided a certain inequality is satisfied. This restriction can be seen manifested in the behavior of the interior graviton wavelength as a function of spacetime dimension.

description: In our system for recording and transmitting lectures over the Internet the board content is sent as vector graphics, yielding a high quality image, while the video of the lecturer is sent as a separate stream. It is easy for the viewer to read the board, but the lecturer appears in a separate window. To eliminate this problem, we segment the lecturer from the video stream and paste his image on the board image at video stream rates. The lecturer can be dimmed by the remote viewer from opaque to semitransparent, or even transparent. This paper explains the two techniques we apply to achieve this: texture classification based segmentation, and segmentation using a novel 3D camera based on the time-of-flight of backscattered light principle. We argue that this technique provides a solution to the divided attention problem which arises when board and lecturer are transmitted in two different streams.

description: Smart contracts are programs running on a blockchain. They are immutable to change, and hence can not be patched for bugs once deployed. Thus it is critical to ensure they are bug-free and well-designed before deployment. A Contract defect is an error, flaw or fault in a smart contract that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. The detection of contract defects is a method to avoid potential bugs and improve the design of existing code. Since smart contracts contain numerous distinctive features, such as the gas system. decentralized, it is important to find smart contract specified defects. To fill this gap, we collected smart-contract-related posts from Ethereum StackExchange, as well as real-world smart contracts. We manually analyzed these posts and contracts; using them to define 20 kinds of contract defects. We categorized them into indicating potential security, availability, performance, maintainability and reusability problems. To validate if practitioners consider these contract as harmful, we created an online survey and received 138 responses from 32 different countries. Feedback showed these contract defects are harmful and removing them would improve the quality and robustness of smart contracts. We manually identified our defined contract defects in 587 real world smart contract and publicly released our dataset. Finally, we summarized 5 impacts caused by contract defects. These help developers better understand the symptoms of the defects and removal priority.

description: We explore the impact of geometrical corrugations on the near-wall flow properties of a soft-material driven in a confined rough microchannel. By means of numerical simulations, we perform a quantitative analysis of the relation between the flow rate $Φ$ and the wall stress $σ_w$ for a number of setups, by changing both the roughness values as well as the roughness shape. Roughness suppresses the flow, with the existence of a characteristic value of $σ_w$ at which flow sets in. Just above the onset of flow, we quantitatively analyze the relation between $Φ$ and $σ_w$. While for smooth walls a linear dependency is observed, steeper behaviours are found to set in by increasing wall roughness. The variation of the steepness, in turn, depends on the shape of the wall roughness, wherein gentle steepness changes are promoted by a variable space localization of the roughness.

description: We use data from the BIMA Survey of Nearby Galaxies (SONG) to investigate the relationship between ellipticity and central mass concentration in barred spirals. Existing simulations predict that bar ellipticity decreases as inflowing mass driven by the bar accumulates in the central regions, ultimately destroying the bar. Using the ratio of the bulge mass to the mass within the bar radius as an estimate of the central mass concentration, we obtain dynamical mass estimates from SONG CO 1-0 rotation curve data. We find an inverse correlation between bar ellipticity and central mass concentration, consistent with simulations of bar dissolution.

description: Recent analyses of the cosmic microwave background (CMB) and the Lyman-alpha forest indicate a mild preference for a deviation from a power law primordial matter power spectrum (a so-called negative `running'). We use an extension to the BAHAMAS suite of cosmological hydrodynamic simulations to explore the effects that a running scalar spectral index has on large-scale structure (LSS), using Planck CMB constraints to initialize the simulations. We focus on 5 key statistics: i) the non-linear matter power spectrum ii) the halo mass function; iii) the halo two-point auto correlation function; iv) total mass halo density profiles; and v) the halo concentration-mass relation. In terms of the matter power spectrum, we find that a running scalar spectral index affects all k-scales examined in this study, with a negative (positive) running leading to an amplification (suppression) of power. These effects should be easily detectable with upcoming surveys such as LSST and Euclid. In the mass range sampled, a positive running leads to an increase in the mass of galaxy groups and clusters, with the favoured negative running leading to a decrease in mass of lower-mass (M ~ 10^13 M_solar) halos. Changes in the mass are generally confined to 5-10% which, while not insignificant, cannot by itself reconcile the claimed tension between the primary CMB and cluster number counts. We find that running does not significantly affect the shapes of density profiles of matched halos, changing only their amplitude. Finally, we demonstrate that the observed effects on LSS due to a running scalar spectral index are separable from those of baryonic effects to typically a few percent precision.

description: It is shown that certain global obstructions to gauge-invariance in chiral gauge theory, described in the continuum by Alvarez-Gaume and Ginsparg, are exactly reproduced on the lattice in the Overlap formulation at small non-zero lattice spacing (i.e. close to the classical continuum limit). As a consequence, the continuum anomaly cancellation condition $d_R^{abc}=0$ is seen to be a necessary (although not necessarily sufficient) condition for anomaly cancellation on the lattice in the Overlap formulation.

description: Human bodies exhibit various shapes for different identities or poses, but the body shape has certain similarities in structure and thus can be embedded in a low-dimensional space. This paper presents an autoencoder-like network architecture to learn disentangled shape and pose embedding specifically for the 3D human body. This is inspired by recent progress of deformation-based latent representation learning. To improve the reconstruction accuracy, we propose a hierarchical reconstruction pipeline for the disentangling process and construct a large dataset of human body models with consistent connectivity for the learning of the neural network. Our learned embedding can not only achieve superior reconstruction accuracy but also provide great flexibility in 3D human body generation via interpolation, bilinear interpolation, and latent space sampling. The results from extensive experiments demonstrate the powerfulness of our learned 3D human body embedding in various applications.

description: We study the axial-vector and the induced pseudoscalar form factors associated with the weak transitions between the octet baryon members in nuclear medium, using a covariant constituent quark model. We extend previous calculations of the axial transition form factors from the vacuum (free space) to the nuclear medium (symmetric nuclear matter). The extension of the model to the nuclear medium takes into account the modifications of the properties of hadrons in the medium (masses and coupling constants), as determined by the quark-meson coupling model. The axial-vector ($G_A$) and the induced pseudoscalar ($G_P$) form factors are evaluated for different values of the nuclear density $ρ$ in terms of the square transfer momentum $q^2= -Q^2$. We conclude that, in general, the $G_A$ and $G_P$ form factors are reduced in the nuclear medium. The reduction is stronger for light baryons and high densities. The medium modifications are milder for the heavier octet baryons, particularly at large $Q^2$. The calculations presented here can be used to estimate the cross sections of neutrino and antineutrino scattering with nucleus, and neutrino and antineutrino scattering with hyperons bound to a nucleus, as well as those in the cores of compact stars.

Academic integrity & plagiarism : The Librarian’s Role in Encouraging AI and Preventing Plagiarism
Creators: name: Hendrix, Beth
Publisher: name: The University of British Columbia
Year: 2017

description: When many students enter higher education, they bring with them the notion that information is free – a result of sharing and borrowing in the online experience. As trusted and impartial members of the campus community, librarians play an important role in dispelling this notion by integrating anti-plagiarism techniques into information literacy instruction sessions. This is the case at the University of Idaho, where information literacy is embedded in the core English course for first-year students. But instead of framing the topic as academic dishonesty, we rebranded our plagiarism module as “Characteristics of Academic Integrity” and elevated our focus from simply how to avoid plagiarism but why it matters. Using the concepts that information has value and scholarship is a conversation, we designed an instruction module that highlights honesty, trust, fairness, respect, and responsibility in scholarly research; emphasizes the responsibilities inherent in academic writing; integrates with information literacy concepts; and aligns with university goals for student learning. This talk outlines our step-by-step process for developing and delivering our Academic Integrity module, including strategies for integrating key information literacy concepts, and activities for helping students identify information that should be cited in their research.

A mechanism for balancing accuracy and scope in cross-machine black-box GPU performance modeling

description: The ability to model, analyze, and predict execution time of computations is an important building block supporting numerous efforts, such as load balancing, performance optimization, and automated performance tuning for high performance, parallel applications. In today's increasingly heterogeneous computing environment, this task must be accomplished efficiently across multiple architectures, including massively parallel coprocessors like GPUs. To address this challenge, we present an approach for constructing customizable, cross-machine performance models for GPU kernels, including a mechanism to automatically and symbolically gather performance-relevant kernel operation counts, a tool for formulating mathematical models using these counts, and a customizable parameterized collection of benchmark kernels used to calibrate models to GPUs in a black-box fashion. Our approach empowers a user to manage trade-offs between model accuracy, evaluation speed, and generalizability. A user can define a model and customize the calibration process, making it as simple or complex as desired, and as application-targeted or general as desired. To evaluate our approach, we demonstrate both linear and nonlinear models; each example models execution times for multiple variants of a particular computation: two matrix multiplication variants, four Discontinuous Galerkin (DG) differentiation operation variants, and two 2-D five-point finite difference stencil variants. For each variant, we present accuracy results on GPUs from multiple vendors and hardware generations. We view this customizable approach as a response to a central question in GPU performance modeling: how can we model GPU performance in a cost-explanatory fashion while maintaining accuracy, evaluation speed, portability, and ease of use, an attribute we believe precludes manual collection of kernel or hardware statistics.

Suppression of scalar mediated FCNCs in a $SU(3)_c\times SU(3)_L\times U(1)_X$-model

description: The models based on $SU(3)_C\times SU(3)_L\times U(1)_X$ gauge symmetry (331-models) have been advocated to explain the number of fermion families. These models place one quark family to a different representation than the other two. The traditional 331-models are plagued by scalar mediated quark flavour changing neutral currents (FCNC) at tree-level. So far there has been no concrete mechanisms to suppress these FCNCs in 331-models. Recently it has been shown that the Froggatt-Nielsen mechanism can be incorporated into the 331-setting in an economical fashion (FN331-model). The FN331-model explains both the number of fermion families in nature and their mass hierarchy simultaneously. In this work we study the Higgs mediated quark FCNCs in FN331-model. The flavour violating couplings of quarks are suppressed by the ratio of the $SU(2)_L \times U(1)_Y$ and $SU(3)_L\times U(1)_X$ breaking scales. We find that the $SU(3)_L\times U(1)_X$-breaking scale can be as low as 5 TeV in order to pass the flavour bounds.

description: Abstracting from potential incentive costs, both theoretical and applied research on contracts and contract choice suggest that bundling multiple contracts may be optimal. With the abundance of risk and uncertainty, especially among low-income environments that are often ill-prepared, the design and commercial success of contracts for mitigating these risks remain crucial. This dissertation brings together applied microeconomic theory along with careful empirical analyses to study three issues about contracts and risks, with implications for the functioning of markets, financial inclusion, unequal impacts of climate extremes and the design of insurance and financial contracts aim at mitigating environmental risks that confront society.
      Chapter 2 studies the potential moral hazard and welfare consequences of interlinking credit with insurance market contracts, establishing that interlinking these two markets not only increases insurance demand, but induces large moral hazard effects in develop- ing countries. Chapter 3 examines environmental risks and their differential impacts on human capital investments, specifically, documenting how Harmattan-induced “Meningitis” outbreaks potentially explain the observed gender gaps in educational attainments in Niger. Chapter 4 evaluates the impact of informal risk-sharing schemes on the adoption of “index” insurance contracts aimed at mitigating climate risks among low-income societies. Two com- peting forces are identified to show that informal network schemes have ambiguous effect on the demand for formal index insurance, which provides novel explanations for two empirical puzzles about index contracts along with an experimental evidence from rural India. The third project connects the first two via contracts and environmental risks, respectively.

description: We construct the first examples of continuous families of isospectral Riemannian metrics that are not locally isometric on closed manifolds, more precisely, on $S^n\times T^m$, where $T^m$ is a torus of dimension $m\ge 2$ and $S^n$ is a sphere of dimension $n\ge 4$. These metrics are not locally homogeneous; in particular, the scalar curvature of each metric is nonconstant. For some of the deformations, the maximum scalar curvature changes during the deformation.

description: We consider a project that consists of a set of activities performed in parallel under constraints on their start and finish times, including start-finish precedence relationships, release start times, release end times, and deadlines. The problems of interest are to decide on the optimal schedule of the activities to minimize both the maximum flow-time over all activities, and the project makespan. We formulate these problems as bi-objective optimization problems in the framework of tropical mathematics which investigates the theory and applications of algebraic systems with idempotent operations and has various applications in management science and operations research. Then, the use of methods and techniques of tropical optimization allows to derive complete Pareto-optimal solutions of the problems in a direct explicit form ready for further analysis and straightforward computation. We discuss the computational complexity of the solution and give illustrative examples.

description: Within the intensively used agricultural landscape many common species as such are nowadays restrained to linear structures like railway embankments or roadsides. Regionally linear structures have got an important function for the maintenance of the regional species diversity. Linear structure of high age may be growing places for rare and little moving plants; but these structures are indeed no compensation for near-natural ecosystems, the more so as they themselves are endangered. Roadsides and railways contribute to the spreading of species especially when they are built, because the todays technical possibilities allow earth movements of unexpected dimensions. A moving distinctly along the linear structure is only possible, if there are additional possibilities of establishing, at least for pioneer species. Precondition is, however, an open respectively disturbed Vegetation cover. From the geobotanical point of view, the netting functions of linear structures are of low importance, especially in relation to the neighbouring ecosystems. Roadsides first of all are netting roadsides, nothing more, but also nothing less. Investigations should be done to the following aspects: - Influence of the age of linear structures to the species diversity. - Efficiency of surviving of endangered plant species. - Effects of the unfavorable ratio circumference : area. - Experimental investigations of spreading phenomena. - Importance of linear structures to the Vegetation of other continents than Europe. This however doesnt mean, that the object of investigation „linear structures" will be finally delt with, because of innovations in the traffic technics habitat conditions and species combinations will change.

Economic Policies, Volatility and Development
Creators: Tapia, Heriberto
Publisher: name: Columbia University
Year: 2012
Subjects: Economics

description: This dissertation offers an integrated collection of essays that seek to understand how economic policies and output volatility of countries depend on their level of development. Chapter 1 presents a general introduction, with the motivation and main results of the project. Chapter 2 introduces the main theoretical piece: a model that explains endogenous limited liability rules and market failures, using a dynamic environment with asymmetric information, with emphasis on wealth effects. Chapter 3 discusses why poor countries are more volatile than rich countries, from an empirical and theoretical perspective. Chapter 4 investigates how the structure of ownership (public, private, foreign) of strategic productive activities in the economy can change along the development path. Chapter5 develops the analytical and numerical foundations of the two-period model used in Chapters 1, 3 and 4, which corresponds to a reduced form of the model developed in Chapter 2.
Outburst Photometry of the Eclipsing Dwarf Nova GY Cancri

description: We observed the ROSAT-selected eclipsing dwarf nova GY Cnc (=RX J0909.8+1849) during the 2001 November outburst. We refined the orbital period to be 0.17544251(5) d. The fading portion of the outburst was indistinguishable from those of typical dwarf novae with similar orbital periods. However, the signature of orbital humps (or a hot spot) was far less prominently observed in the orbital light curves and eclipse profiles than in usual dwarf novae with similar orbital periods. The combination of low frequency of outbursts and the apparent lack of slowly rising, long outbursts in GY Cnc is difficult to reconcile within the standard framework of dwarf novae. We suspect that GY Cnc may be the first above-the-gap counterpart of unusual eclipsing dwarf novae HT Cas and IR Com.

Extraction of Nematodes from Soil

description: Nematodes are an integral part of the soil biome, ranging from one to ten million per square meter of soil. In order to understand and study the dynamics of the nematode population, their extraction from the soil is a crucial step. Moreover, the attack of plant parasitic nematodes may pave the way for other pathogens to enter. So, their detection is not only necessary for diagnosing nematode damage but also to prevent the formation of other disease complexes. Based on certain parameters like nematode size, sedimentation rate between them, and soil particles, it is possible to extract the nematode population by sieving and decantation methods. This is one of the simple and basic methodologies adopted for extracting nematodes. However, for isolating large, slow-moving sedentary nematodes, other methods are recommended. By this method, we can obtain most of the active, inactive, or dead nematodes.
Feynman diagrams as a weight system: four-loop test of a four-term relation

description: At four loops there first occurs a test of the four-term relation derived by the second author in the course of investigating whether counterterms from subdivergence-free diagrams form a weight system. This test relates counterterms in a four-dimensional field theory with Yukawa and $ϕ^4$ interactions, where no such relation was previously suspected. Using integration by parts, we reduce each counterterm to massless two-loop two-point integrals. The four-term relation is verified, with $ = 0 - 3ζ_3 + 6ζ_3 - 3ζ_3 = 0$, demonstrating non-trivial cancellation of the trefoil knot and thus supporting the emerging connection between knots and counterterms, via transcendental numbers assigned by four-dimensional field theories to chord diagrams. Restrictions to scalar couplings and renormalizable interactions are found to be necessary for the existence of a pure four-term relation. Strong indications of richer structure are given at five loops.

Quadratic Chabauty for (bi)elliptic curves and Kim's conjecture

Publisher: name: arXiv

Subjects: subject: Number Theory (math.NT)

description: We explore a number of problems related to the quadratic Chabauty method for determining integral points on hyperbolic curves. We remove the assumption of semistability in the description of the quadratic Chabauty sets $\mathcal{X}(\mathbb{Z}_p)_2$ containing the integral points $\mathcal{X}(\mathbb{Z})$ of an elliptic curve of rank at most $1$. Motivated by a conjecture of Kim, we then investigate theoretically and computationally the set-theoretic difference $\mathcal{X}(\mathbb{Z}_p)_2\setminus \mathcal{X}(\mathbb{Z})$. We also consider some algorithmic questions arising from Balakrishnan--Dogra's explicit quadratic Chabauty for the rational points of a genus-two bielliptic curve. As an example, we provide a new solution to a problem of Diophantus which was first solved by Wetherell. Computationally, the main difference from the previous approach to quadratic Chabauty is the use of the $p$-adic sigma function in place of a double Coleman integral.

description: The paper deals for the very first time with the spontaneous flora of a tramway in Germany. The narrow-gauged tramway system of Braunschweig is fully independent from the railway network of the German Railway (DB). 225 species have been found on its tracks. Within less than 30 years a subamount of the 711 species found on the intra-urban railway area established themselves on the tramway tracks although there is no connection between them.
Capacity of Quantum Channels Using Product Measurements

description: The capacity of a quantum channel for transmission of classical information depends in principle on whether product states or entangled states are used at the input, and whether product or entangled measurements are used at the output. We show that when product measurements are used, the capacity of the channel is achieved with product input states, so that entangled inputs do not increase capacity. We show that this result continues to hold if sequential measurements are allowed, whereby the choice of successive measurements may depend on the results of previous measurements. We also present a new simplified expression which gives an upper bound for the Shannon capacity of a channel, and which bears a striking resemblance to the well-known Holevo bound.

Pauli Noise Learning for Mid-Circuit Measurements

description: Current benchmarks for mid-circuit measurements (MCMs) are limited in scalability or the types of error they can quantify, necessitating new techniques for quantifying their performance. Here, we introduce a theory for learning Pauli noise in MCMs and use it to create MCM cycle benchmarking, a scalable method for benchmarking MCMs. MCM cycle benchmarking extracts detailed information about the rates of errors in randomly compiled layers of MCMs and Clifford gates, and we demonstrate how its results can be used to quantify correlated errors during MCMs on current quantum hardware. Our method can be integrated into existing Pauli noise learning techniques to scalably characterize and benchmark wide classes of circuits containing MCMs.
