description: Link prediction is a paradigmatic problem in network science with a variety of applications. In latent space network models this problem boils down to ranking pairs of nodes in the order of increasing latent distances between them. The network model with hyperbolic latent spaces has a number of attractive properties suggesting it must be a powerful tool to predict links, but the past work in this direction reported mixed results. Here we perform systematic investigation of the utility of latent hyperbolic geometry for link prediction in networks. We first show that some measures of link prediction accuracy are extremely sensitive with respect to inaccuracies in the inference of latent hyperbolic coordinates of nodes, so that we develop a new coordinate inference method that maximizes the accuracy of such inference. Applying this method to synthetic and real networks, we then find that while there exists a multitude of competitive methods to predict obvious easy-to-predict links, among which hyperbolic link prediction is rarely the best but often competitive, it is the best, often by far, when the task is to predict less obvious missing links that are really hard to predict. These links include missing links in incomplete networks with large fractions of missing links, missing links between nodes that do not have any common neighbors, and missing links between dissimilar nodes at large latent distances. Overall these results suggest that the harder a specific link prediction task is, the more seriously one should consider using hyperbolic geometry.
An ADM 3+1 formulation for Smooth Lattice General Relativity

Publisher: name: arXiv
Year: 1997
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: A new hybrid scheme for numerical relativity will be presented. The scheme will employ a 3-dimensional spacelike lattice to record the 3-metric while using the standard 3+1 ADM equations to evolve the lattice. Each time step will involve three basic steps. First, the coordinate quantities such as the Riemann and extrinsic curvatures are extracted from the lattice. Second, the 3+1 ADM equations are used to evolve the coordinate data, and finally, the coordinate data is used to update the scalar data on the lattice (such as the leg lengths). The scheme will be presented only for the case of vacuum spacetime though there is no reason why it could not be extended to non-vacuum spacetimes. The scheme allows any choice for the lapse function and shift vectors. An example for the Kasner $T^3$ cosmology will be presented and it will be shown that the method has, for this simple example, zero discretisation error.

description: We present a concept called the branch-depth of a connectivity function, that generalizes the tree-depth of graphs. Then we prove two theorems showing that this concept aligns closely with the notions of tree-depth and shrub-depth of graphs as follows. For a graph $G = (V,E)$ and a subset $A $ of $E$ we let $λ_G (A)$ be the number of vertices incident with an edge in $A$ and an edge in $E \setminus A$. For a subset $X$ of $V$, let $ρ_G(X)$ be the rank of the adjacency matrix between $X$ and $V \setminus X$ over the binary field. We prove that a class of graphs has bounded tree-depth if and only if the corresponding class of functions $λ_G$ has bounded branch-depth and similarly a class of graphs has bounded shrub-depth if and only if the corresponding class of functions $ρ_G$ has bounded branch-depth, which we call the rank-depth of graphs. Furthermore we investigate various potential generalizations of tree-depth to matroids and prove that matroids representable over a fixed finite field having no large circuits are well-quasi-ordered by the restriction.

description: For a class $\mathcal C$ of graphs, we define $\mathcal C$-edge-brittleness of a graph $G$ as the minimum $\ell$ such that the vertex set of $G$ can be partitioned into sets inducing a subgraph in $\mathcal C$ and there are $\ell$ edges having ends in distinct parts. We characterize classes of graphs having bounded $\mathcal C$-edge-brittleness for a class $\mathcal C$ of forests or a class $\mathcal C$ of graphs with no $K_4\setminus e$ topological minors in terms of forbidden obstructions. We also define $\mathcal C$-vertex-brittleness of a graph $G$ as the minimum $\ell$ such that the edge set of $G$ can be partitioned into sets inducing a subgraph in $\mathcal C$ and there are $\ell$ vertices incident with edges in distinct parts. We characterize classes of graphs having bounded $\mathcal C$-vertex-brittleness for a class $\mathcal C$ of forests or a class $\mathcal C$ of outerplanar graphs in terms of forbidden obstructions. We also investigate the relations between the new parameters and the edit distance.

description: We model large angle intermediate energy pion-pion scattering by the pQCD two-gluon (2g) exchange contribution and discuss the onset of the dominance of the Glauber-Gribov-Landshoff (GGL) component. The pQCD 2g exchange contribution becomes substantial already at $|t|\sim$ 1 GeV^{2}, but the pQCD exchange dominance is deferred to $|t|\sim$ 3 GeV^{2} because of competing multiple soft rescattering effects. Based on the NN and $πN$ total cross section data and Regge factorization, we evaluate the dominant soft contribution to the $ππ$ total cross section and find the results consistent with the ones deduced earlier from the absorption model analysis of the $πN \to X N, X Δ$ data.

description: Phytosterols are known to reduce plasma cholesterol levels and thereby reduce cardiovascular risk. Studies conducted on human and animal models have demonstrated that these compounds have also anti-inflammatory effects. Recently, an experimental colitis model (dextran sulphate sodium-induced) has shown that pre-treatment with phytosterols decreases infiltration of inflammatory cells and accelerates mucosal healing. This study aims to understand the mechanism underlying the colitis by analysing the end-products of the metabolism in distal colon and liver excised from the same mice used in the previous work. In particular, an unsupervised gas chromatography-mass spectrometry (GC-MS) and NMR based metabolomics approach was employed to identify the metabolic pathways perturbed by the dextran sodium sulphate (DSS) insult (i.e. Krebs cycle, carbohydrate, amino acids, and nucleotide metabolism). Interestingly, phytosterols were able to restore the homeostatic equilibrium of the hepatic and colonic metabolome.

description: Recently Watts and Strogatz have given an interesting model of small-world networks. Here we concretise the concept of a ``far away'' connection in a network by defining a {\it far edge}. Our definition is algorithmic and independent of underlying topology of the network. We show that it is possible to control spread of an epidemic by using the knowledge of far edges. We also suggest a model for better advertisement using the far edges. Our findings indicate that the number of far edges can be a good intrinsic parameter to characterize small-world phenomena.

description: We define epsilon factors for irreducible representations of finite general linear groups using Macdonald's correspondence. These epsilon factors satisfy multiplicativity, and are expressible as products of Gauss sums. The tensor product epsilon factors are related to the Rankin-Selberg gamma factors, by which we prove that the Rankin-Selberg gamma factors can be written as products of Gauss sums. The exterior square epsilon factors relate the Jacquet-Shalika exterior square gamma factors and the Langlands-Shahidi exterior square gamma factors for level zero supercuspidal representations. We prove that these exterior square factors coincide in a special case.

New parameters for the asymmetric clan distribution and for the particle leakage from clans in one hemisphere to the opposite one are introduced to effectively classify different classes of collisions. This tool should be used to explore forward-backward multiplicity correlations in AB and pA collisions in present and future experiments at RHIC and LHC.

description: Many immigrants are overqualified in their first job after arrival in the host country. Education‐occupation mismatch can affect the economic integration of immigrants and the returns to education and experience. The extent of this problem has been measured in recent years by means of micro level data in Australia, North America and Europe. However, these papers have typically ignored the importance of allowing for heterogeneity, in particular by qualification level and years in the destination country. In this paper, we use micro data from the 1996, 2001 and 2006 New Zealand censuses to examine differences between each migrant’s actual years of education and the estimated typical years of education in the narrowly defined occupation in which they work. We find that migrants living in New Zealand for less than 5 years are on average overeducated, while earlier migrants are on average undereducated. However, once accounting for heterogeneity, we find that both overeducated and undereducated migrants become, with increasing years of residence in New Zealand, more similar to comparable native born. Convergence from overeducation is stronger than from undereducation.
Gravity from Dirac Eigenvalues

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We study a formulation of euclidean general relativity in which the dynamical variables are given by a sequence of real numbers $λ_{n}$, representing the eigenvalues of the Dirac operator on the curved spacetime. These quantities are diffeomorphism-invariant functions of the metric and they form an infinite set of ``physical observables'' for general relativity. Recent work of Connes and Chamseddine suggests that they can be taken as natural variables for an invariant description of the dynamics of gravity. We compute the Poisson brackets of the $λ_{n}$'s, and find that these can be expressed in terms of the propagator of the linearized Einstein equations and the energy-momentum of the eigenspinors. We show that the eigenspinors' energy-momentum is the Jacobian matrix of the change of coordinates from the metric to the $λ_{n}$'s. We study a variant of the Connes-Chamseddine spectral action which eliminates a disturbing large cosmological term. We analyze the corresponding equations of motion and find that these are solved if the energy momenta of the eigenspinors scale linearly with the mass. Surprisingly, this scaling law codes Einstein's equations. Finally we study the coupling to a physical fermion field.

description: 7-methoxytacrine-4-pyridinealdoxime (7-MEOTA-4-PA, named hybrid 5C) is a compound formerly synthesized and evaluated in vitro, together with 4-pyridine aldoxime (4-PA) and commercial reactivators of acetylcholinesterase (AChE). This compound was designed with the purpose of being a prophylactic reactivator, capable of interacting with different subdomains of the active site of AChE. To investigate these interactions, theoretical results from docking were first compared with experimental data of hybrid 5C, 4-PA, and two commercial oximes, on the reactivation of human AChE (HssAChE) inhibited by VX. Then, further docking studies, molecular dynamics simulations, and molecular mechanics Poisson–Boltzmann surface area calculations, were carried out to investigate reactivation performances, considering the near attack conformation (NAC) approach, prior to the nucleophilic substitution mechanism. Our results helped to elucidate the interactions of such molecules with the different subdomains of the active site of HssAChE. Additionally, NAC poses of each oxime were suggested for further theoretical studies on the reactivation reaction.

In this article, we show that if the limit set $Λ(H)$ of $H$ in $\partial_{c}^{\mathcal{F}\mathcal{Q}}G$ is compact and contains at least three points then the action of the subgroup $H$ on the space of distinct triples $Θ_{3}(Λ(H))$ is properly discontinuous. By applying a result of B. Sun \cite{BinSun}, if the limit set $Λ(H)$ is compact and the action of $H$ on $\partial_{c}^{\mathcal{F}\mathcal{Q}}G$ is non-elementary then $H$ becomes an acylindrically hyperbolic group

Multiplicative semiclassical dynamics and the quantization time

Subjects: subject: Chaotic Dynamics (nlin.CD)

description: We study smooth, caustic-free, chaotic semiclassical dynamics on two-dimensional phase space and find that the dynamics can be approached by an iterative procedure which constructs an approximation to the exact long-time semiclassical propagator. Semiclassical propagation all the way to the Heisenberg time, where individual eigenstates are resolved, can be computed in polynomial time, obviating the need to sum over an exponentially large number of classical paths. At long times, the dynamics becomes quantum-like, given by a matrix of the same dimension as the quantum propagator. This matrix, however, differs both from the quantum and the one-step semiclassical propagators, allowing for the study of the breakdown of the semiclassical approximation. The results shed light on the accuracy of the Gutzwiller trace formula in two dimensions, and on the source of long-time periodic orbit correlations.

description: Previous research in regulatory focus theory and regulatory fit (Higgins, 1997, 2000) has identified two primary orientations and preferred means that people employ in-pursuit of a desired outcome. Promotion focus use eagerness means to approach gains, while prevention focus use vigilance means to avoid losses. These established theories have contributed to our understanding of individual-level differences in various description-based decision tasks, where people learn about choice outcomes through explicit descriptions (Hertwig, Barron, Weber, & Erev, 2004). The primary purpose of this dissertation was to examine the effect of ‘trait-level’ regulatory focus and regulatory fit on decision behavior in a decisions-from-experience task, where choice outcomes are unknown and can only be learned through experience. Specifically, the present studies examine decision behavior in the sampling paradigm (Hertwig et al., 2004; Weber, Shafir, & Blais, 2004), where participants may sample outcomes from the presented decision options before making a consequential decision. In the reported studies, individual differences in regulatory focus orientation were predicted to influence decision behavior (i.e., sampled outcomes and risky choices) above and beyond other relevant dispositional variables, specifically, financial risk tolerance and broad (Big-5) personality traits. Decision behavior was expected to vary by motivational orientation and by its interaction with choice domain (i.e., gain vs. loss problems). A secondary purpose was to examine the effect of financial risk tolerance on risky choices, as well as to explore the relationships between broad personality traits and decision behavior. Three studies (pilot and two main) were conducted. In each study, participants were given a set of four questionnaires and participated in an interactive computer-based (sampling paradigm) game. Because of data quality concerns with the pilot study and Study 1, the interpretations rely on the results from Study 2. Study 2 found trait-level regulatory fit to significantly predict participants’ exploratory (i.e., sampling) behavior. Moreover, Study 2 provided evidence that the frequency of risky choices varied by risk tolerance level. The theoretical implications for regulatory focus orientation and experience-based decision behavior are discussed, and potential avenues for future research are proposed.

description: We study the Diophantine equations obtained by equating a polynomial and the factorial function, and prove the finiteness of integer solutions under certain conditions. For example, we show that there exists only finitely many $l$ such that $l!$ is represented {by} $N_A(x)$, where $N_A$ is a norm form constructed from the field norm of a field extension $K/\mathbf Q$. We also deal with the equation $N_A(x)=l!_S$, where $l!_S$ is the Bhargava factorial. In this paper, we also show that the Oesterlé-Masser conjecture implies that for any infinite subset $S$ of $\mathbf Z$ and for any polynomial $P(x)\in\mathbf Z[x]$ of degree $2$ or more the equation $P(x)=l!_S$ has only finitely many solutions $(x,l)$. For some special infinite subsets $S$ of $\mathbf Z$, we can show the finiteness of solutions for the equation $P(x)=l!_S$ unconditionally.

description: The British North American colonies were the first western economies to rely on colonyspecific legislature-issued paper money as a medium of exchange for domestic transactions. The creation of paper money regimes arose piecemeal among the colonies, making each story unique. Maryland’s story is the most complex among the colonies, since the emission of paper money resulted from an attempt to control and manipulate the tobacco market. The paper discusses how market forces, legal maneuverings, and the power of various constituencies combined to shape Maryland’s particular paper money system, assesses its successes and failures, and identifies the winners and losers among Maryland’s political classes as a result of this paper money experiment.

description: An approach is described to calculate Generalized Parton Distributions (GPDs) in Constituent Quark Models (CQM). The GPDs are obtained from wave functions to be evaluated in a given CQM. The general relations linking the twist-two GPDs to the form factors and to the leading twist quark densities are recovered. Results for the leading twist, unpolarized GPD in the Isgur and Karl model are presented.

Measurements of top-quark pair spin correlations in the $eμ$ channel at $\sqrt{s} = 13$ TeV using $pp$ collisions in the ATLAS detector

Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: A measurement of observables sensitive to spin correlations in $t\bar{t}$ production is presented, using 36.1 fb$^{-1}$ of $pp$ collision data at $\sqrt{s} = 13$ TeV recorded with the ATLAS detector at the Large Hadron Collider. Differential cross-sections are measured in events with exactly one electron and one muon with opposite-sign electric charge as a function of the azimuthal opening angle and the absolute difference in pseudorapidity between the electron and muon candidates in the laboratory frame. The azimuthal opening angle is also measured as a function of the invariant mass of the $t\bar{t}$ system. The measured differential cross-sections are compared to predictions by several NLO Monte Carlo generators and fixed-order calculations. The observed degree of spin correlation is somewhat higher than predicted by the generators used. The data are consistent with the prediction of one of the fixed-order calculations at NLO, but agree less well with higher-order predictions. Using these leptonic observables, a search is performed for pair production of supersymmetric top squarks decaying into Standard Model top quarks and light neutralinos. Top squark masses between 170 and 230 GeV are largely excluded at the 95% confidence level for kinematically allowed values of the neutralino mass.

Topological Quantum Computation
Creators: name: Bonesteel, Nick
Publisher: name: The University of British Columbia
Year: 2016

description: Certain exotic states of matter, so-called non-Abelian states, have the potential to provide a natural medium for the storage and manipulation of quantum information. In these states, localized particle-like excitations (quasiparticles) possess quantum numbers which are in many ways analogous to ordinary spin quantum numbers. However, unlike ordinary spins, the quantum information associated with these quantum numbers is stored globally, throughout the entire system, and so is intrinsically protected against decoherence. Quantum computation can then be carried out by dragging these quasiparticles around one another so that their trajectories sweep out world-lines in 2+1-dimensional space-time. The resulting computation depends only on the topology of the braids formed by these world-lines, and thus is robust against error. In these lectures I will review the theory of non-Abelian states, including the necessary mathematical background for describing the braiding of their quasiparticles. I will then introduce the basic ideas behind topological quantum computation and demonstrate explicitly that certain non-Abelian quasiparticles can indeed by used for universal quantum computation by showing how any quantum algorithm can be "compiled" into a braiding pattern for them. I will also discuss the most promising experimental systems for realizing non-Abelian quasiparticles, focusing primarily on fractional quantum Hall states.
Behavior of the Dripping Faucet over a Wide Range of the Flow Rate

description: The time interval of successive water-drips from a faucet was examined over a wide range of the flow rate. The dripping interval alternately exhibits a stable state and a chaotic state as the flow rate increases. In the stable state, the volume of the drip is kept constant at fixed flow rates, and the constant volume increases with the flow rate. In the chaotic state, in addition to a mechanics that the drip is torn by its own weight, the vibration of the drip on the faucet takes part in the strange behavior of the interval.

description: Da es nicht möglich ist, durch Verhaltensbeobachtungen festzustellen, ob jemand absichtlich oder unabsichtlich etwas tut oder nicht tut, ist es notwendig, unabhängig von einer behavioristischen Sichtweise die Kriterien für die Annahme von Handlungen und Unterlassungshandlungen herauszuarbeiten und zu zeigen, dass Handlungen und Unterlassungshandlungen nicht mit Ereignissen identifiziert werden können. Da Autoren den Zusammenhang zwischen ‚retten’ und ‚nicht töten’ und ‚nicht retten’ und ‚töten’ falsch interpretiert haben, lässt sich das gegenwärtig vieldiskutierte Problem der negativen Kausalität auflösen.
description: Since it is not possible to maintain in virtue of observable behaviour whether someone intentionally or unintentionally does or does not something, it is necessary apart from a behavioristic view to examine the criteria for actions and omissions and, moreover, to show that actions and omissions cannot be identified with events. As authors have not correctly expounded the connection between ‘saving’ and ‘not killing’ and ‘not saving’ and ‘killing’, the problem presently much discussed about negative causation proves to be dissolved.

description: Recently Bernd Schmidt has given three explicit examples of spacetimes with toroidal null infinities. In this paper all solutions with a toroidal null infinity within Schmidt's metric ansatz (polarized Gowdy models) are constructed. The members of the family are determined by two smooth functions of one variable. For the unpolarized Gowdy models the same kind of analysis carries through.

The Effect of Violent Human Interaction in Eyewitness Memory
Creators: Muniz, Lizandra
Publisher: name: Columbia University
Year: 2011
Subjects: subject: Psychology
subject: FOS: Psychology

description: Years of research in eyewitness reliability have proved that human memory can be fallible producing perpetrator misidentification thus leaving real criminals out on the streets. Many innocent suspects have been wrongfully identified and convicted to years of prison just because the jury and the judge put heavy emphasis on the eyewitness statement. New DNA technology has been able to prove the innocence of many convicted suspects, but it is still a small fraction of the possible unjust imprisonments in the United States. This study aims to explore witnesses fear and empathy as predictors of memory accuracy and correct perpetrator identification from a live lineup. In the first condition subjects will witness a staged violent attack from a person to another person. In the second condition subjects will witness a violent attack from a person towards a non-human target. It is expected that eyewitnesses will better recall the specifics of the event and more accurately identify the perpetrator in the human-object interaction than in the human-human interaction.
Semiclassical dynamical localization and the multiplicative semiclassical propagator

description: We describe an iterative approach to computing long-time semiclassical dynamics in the presence of chaos, which eliminates the need for summing over an exponentially large number of classical paths, and has good convergence properties even beyond the Heisenberg time. Long-time semiclassical properties can be compared with those of the full quantum system. The method is used to demonstrate semiclassical dynamical localization in one-dimensional classically diffusive systems, showing that interference between classical paths is a sufficient mechanism for limiting long-time phase space exploration.

description: This paper uses data from the New Zealand Census to examine how the supply of recent migrants in particular skill groups affects the geographic mobility of the New Zealand-born and earlier migrants. We identify the impact of recent migration on mobility using the ‘area-analysis’ approach, which exploits the fact that immigration is spatially concentrated, and thus a change in the local supply of migrants in a particular skill group should have an impact on the mobility of similarly skilled nonmigrants in that local labour market. Overall, our results provide little support for the hypothesis that migrant inflows displace either the NZ-born or earlier migrants with similar skills in the areas that new migrants are settling. If anything, they suggest that there are positive spillovers between recent migrants and other individuals that encourage individuals to move to or remain in the areas in which similarly skilled migrants are settling. Thus, it appears unlikely that internal mobility moderates any potential impacts of immigration on labour or housing markets in New Zealand.

description: Why should we study mesons in 2002? Two approaches to relating quark and gluon dynamics to hadron physics, namely QCD sum rules and effective field theories, are briefly discussed. These are linked by progress in the study of strong QCD, both by lattice Monte Carlo methods and in the continuum. These provide the translation from quark dynamics to hadron physics and back again. Scope for more theoretical work and further experiments to elucidate the nature of the QCD vacuum and its precise relation to scalar mesons and their interactions is outlined.

description: We study the spin of primordial black holes produced by the collapse of large inhomogeneities in the early universe. Since such primordial black holes originate from peaks, that is, from maxima of the local overdensity, we resort to peak theory to obtain the probability distribution of the spin at formation. We show that the spin is a first-order effect in perturbation theory: it results from the action of first-order tidal gravitational fields generating first-order torques upon horizon-crossing, and from the asphericity of the collapsing object. Assuming an ellipsoidal shape, the typical value of the dimensionless parameter $a_{\rm s}=S/G_N M^2$, where $S$ is the spin and $M$ is the mass of the primordial black hole, is about $σ_δ\sqrt{1-γ^2}/2π$. Here, $σ^2_δ$ is the variance of the overdensity at horizon crossing and the parameter $γ$ is a measure of the width of the power spectrum giving rise to primordial black holes. One has $γ=1$ for monochromatic spectra. For these narrow spectra, the suppression arises because the velocity shear, which is strongly correlated with the inertia tensor, tends to align with the principal axis frame of the collapsing object. Typical values of $a_{\rm s}$ are at the percent level.
