description: A cyclically dominating three-species ecosystem, modeled within the framework of rock-paper-scissor game, is studied in presence of natural death and an effect of the environment. The environmental impact is parameterized along with the death rates in the rate equation of the species densities. Monte-Carlo simulations on this system reveal that the population density bears the signature of first-order and second-order phase transitions in different regimes of the parameters representing natural deaths of the species. The connection of this phenomena with the phase transitions is also supported by the behavior of the basin entropy calculated for the system. The density of total population evidently becomes an order parameter with respect to the change in environmental impact on the system.

Yellow fever in South America: The role of environment and host on transmission dynamics
Creators: name: Hamlet, Arran Timothy Patrick
Publisher: name: Imperial College London
Year: 2020

description: Yellow fever (YF) is an arbovirus that affects both humans and non-human primates (NHPs). Despite a longstanding recognition of YF as a significant public health problem, many aspects of its underlying transmission and maintenance remain unknown. These knowledge gaps continue to exist even with the increasing availability of data, techniques and recent large-scale outbreaks in South America and Africa.Using several statistical and machine learning methods, I investigate the role of climate, environment and host in predicting the suitability of YF across South America, as an average, seasonally and inter-annually. Following Iexamine the role of seasonality of agriculture, as a proxy for exposure, on human and NHP YF reports in Brazil. To contextualise these predictions and recommendations, I calculate and describe population-level YF vaccination coverage estimates (1940-2050) across Africa and South America, as well as the interactive web-based platform these are published on. Finally, I predict the distribution and density of NHP genera across the South-East of Brazil, and use this ina stochastic multi-species, age structured, meta-population model to explore the role of NHP genera on viral maintenance, and the potential for the establishment of endemicity in the state of Rio de Janeiro.Overall this thesis describes several key aspects necessary to understand the enigma of YF transmission in South America. A greater understanding of climate and environment allows for the possibility of forecasting periods of heightened transmission which could inform pro-active surveillance and vaccination, supported through our vaccination coverage estimates. Finally, by providing insights into the role of NHP genera on maintenance and critical community sizes for YFV transmission, I can highlight the potential for endemicity to be established.

description: The cross section for coherent $ω$-meson photoproduction off the deuteron has been measured for the first time as a function of the momentum transfer $t = (P_γ-P_ω)^2$ and photon energy $E_γ$ using the CLAS detector at the Thomas Jefferson National Accelerator Facility. The cross sections are measured in the energy range $1.4 < E_γ < 3.4$ GeV. A model based on $ω-N$ rescattering is consistent with the data at low and intermediate momentum transfer, $|t|$. For $2.8 < E_γ < 3.4$ GeV, the total cross-section of $ω-N$ scattering, based on fits within the framework of the Vector Meson Dominance model, is in the range of 30-40 mb.

description: The Product Replacement Algorithm is a practical algorithm for generating random elements of a finite group. The algorithm can be described as a random walk on a graph whose vertices are the generating k-tuples of the group (for a fixed integer k). We show that there is a function c(r) such that for any finite simple group of Lie type, with Lie rank r, the product replacement graph of the generating k-tuples is connected for any k > c(r). The proof uses results of Larsen and Pink and does not rely on the classification of finite simple groups.

description: We study the formation of galaxies by using $N$-body/hydrodynamics simulations to investigate how baryons collect at the centre of dark matter halos. We treat the dark matter as a collisionless fluid and the baryons as an ideal gas. We include the effects of gravity, pressure gradients, hydrodynamical shocks, and radiative energy losses, but we neglect star formation. Our initial conditions assume a flat universe dominated by cold dark matter with a mean baryon abundance of 10\% by mass. Typical halos form through the merging of a few smaller systems which had themselves formed in a similar manner at higher redshift. The gas collects at the bottom of dark matter potential wells as soon as these are properly resolved by our simulations. There it settles into cold, tightly bound disks, and it remains cold during subsequent evolution. As their halos coalesce, these disks merge on a timescale that is consistent with dynamical friction estimates based on their {\it total} (gas + surrounding dark matter) mass. Both the merger rates of the disks and their mass spectrum are in remarkably good agreement with recent analytic models that describe the evolution of {\it dark halos} in a hierarchical universe. This very simple model of galaxy formation suffers from serious shortcomings. It predicts that most baryons should be locked up in galaxies, whereas in the real universe most baryons are thought to lie outside visible galaxies. In addition, it predicts the specific angular momentum of a disk to be only about 20\% that of its surrounding halo, corresponding to a radius smaller than that of observed spiral galaxy disks.

description: We study the spectral energy transfer due to wave-triad interactions in the Garrett-Munk spectrum of internal gravity waves (IGWs) based on a numerical evaluation of the collision integral in the wave kinetic equation. Our numerical evaluation builds on the reduction of the collision integral on the resonant manifold for a horizontally isotropic spectrum. We directly evaluate the downscale energy flux available for ocean mixing, whose value is in close agreement with the empirical finescale parameterization. We further decompose the energy transfer into contributions from different mechanisms, including local interactions and three types of nonlocal interactions, namely parametric subharmonic instability (PSI), elastic scattering (ES) and induced diffusion (ID). Through analysis on the role of each type of interaction, we resolve two long-standing paradoxes regarding the mechanism for forward cascade in frequency and zero ID flux for GM76 spectrum. In addition, our analysis estimates the contribution of each mechanism to the energy transfer in each spectral direction, and reveals new understanding of the importance of local interactions and ES in the energy transfer.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Multi-photon emissions constitute a fundamental source of noise in quantum repeaters and other quantum communication protocols when probabilistic photon sources are employed. In this paper, it is shown that by alternating the Bell state measurement (BSM) basis in concatenated entanglement swapping links one can automatically identify and discard many errors from stimulated multi-photon emissions. The proposed protocol is shown to completely eliminate the dominant quadratic growth of multi-photon errors with the length of the repeater chain. Furthermore, it is shown that the protocol can be employed in satellite-assisted entanglement distribution links to enable links which are more robust in the presence of imbalanced channel losses. The analysis introduces a convenient calculus based on Clifford algebra for modeling concatenated entanglement swapping links with multi-photon emissions. In particular, we present a compact expression for the fidelity of the Bell state produced by a repeater chain of arbitrary length including noise from double-pair emissions.

description: Superintegrable Hamiltonian systems in a two-dimensional Euclidean space are considered. We present all real standard potentials that allow separation of variables in polar coordinates and admit an independent fourth-order integral of motion. The general form of the potentials satisfies a linear ODE. In the classical case, the standard potentials coincide with the Tremblay-Turbiner-Winternitz (TTW) or Post-Winternitz (PW) models. In the quantum case new superintegrable systems are obtained, in addition to the TTW and PW ones. Their classical limit is free motion.

A Lattice Formulation of Two Dimensional Topological Field Theory

description: We propose a non-perturbative criterion to investigate whether supersymmetric lattice gauge theories preserving partial SUSY can have the desired continuum limit or not. Since the target continuum theories of the lattice models are extended supersymmetric gauge theories including the topological field theory (TFT) as a special subsector, the continuum limits of them should reproduce the properties of the TFT. Therefore, whether the property of the TFT can be recovered at the continuum limit becomes a non-perturbative criterion. Then we accept it as a criterion. In this paper, among the topological properties, we investigate the BRST cohomology on the two dimensional ${\mathcal N}=(4,4)$ CKKU lattice model without moduli fixing mass term. We show that the BRST cohomology in the target continuum theory cannot be realized from the BRST cohomology on the lattice. From this result, we obtain the possible implication that the ${\mathcal N} = (4,4)$ CKKU model cannot recover the target continuum theory if the non-perturbative effects are taken into account.

Power-law fluctuations near critical point in semiconductor lasers with delayed feedback

description: Since the analogy between laser oscillation and second-order phase transition was indicated in the 1970s, dynamical fluctuations on lasing threshold inherent in critical phenomena have gained significant interest. Here, we numerically and experimentally demonstrate that a semiconductor laser subject to delayed optical feedback can exhibit unusual large intensity fluctuations characterized by power-law distributions. Such an intensity fluctuation consists of distinct intermittent bursts of light intensity, whose peak values attain tens of times the intensity of the maximum gain mode. This burst behavior emerges when a laser with a long time delay (over 100 ns) and an optimal feedback strength operates around the lasing threshold. The intensity and waiting time statistics follow power-law-like distributions. This implies the emergence of nonequilibrium critical phenomena, namely self-organized criticality. In addition to numerical results, we report experimental results that suggest the power-law intensity dynamics in a semiconductor laser with delayed feedback.

description: The calculation of the full counting statistics of the charge within a finite interval of an interacting one-dimensional system of electrons is a fundamental, yet as of now unresolved problem. Even in the non-interacting case, charge counting turns out to be more difficult than anticipated because it necessitates the calculation of a nontrivial determinant and requires regularization. Moreover, interactions in a one-dimensional system are best described using bosonization. However, this technique rests on a long-wavelength approximation and is a priori inapplicable for charge counting due to the sharp boundaries of the counting interval. To mitigate these problems, we investigate the counting statistics using several complementary approaches. To treat interactions, we develop a diagrammatic approach in the fermionic basis, which makes it possible to obtain the cumulant generating function up to arbitrary order in the interaction strength. Importantly, our formalism preserves charge quantization in every perturbative order. We derive an exact expression for the noise and analyze its interaction-dependent logarithmic cutoff. We compare our fermionic formalism with the results obtained by other methods, such as the Wigner crystal approach and numerical calculations using the density-matrix renormalization group. Surprisingly, we show good qualitative agreement with the Wigner crystal for weak interactions, where the latter is in principle not expected to apply.

description: We study the numerical realisation of optimal consensus control laws for agent-based models. For a nonlinear multi-agent system of Cucker-Smale type, consensus control is cast as a dynamic optimisation problem for which we derive first-order necessary optimality conditions. In the case of a smooth penalization fo the control energy, the optimality system is numerically approximated via a gradient-descent method. For sparsity promoting, non-smooth $\ell_1$-norm control penalizations, the optimal controllers are realised by means of heuristic methods. For an increasing number of agents, we discuss the approximation of the consensus control problem by following a mean-field modelling approach.

description: We have tested Haldane's ``fractional-Pauli-principle'' description of excitations around the $ν= 1/3$ state in the FQHE, using exact results for small systems of electrons. We find that Haldane's prediction $β= \pm 1/m$ for quasiholes and quasiparticles, respectively, describes our results well with the modification $β_{qp} = 2-1/3$ rather than $-1/3$. We also find that this approach enables us to better understand the {\it energetics\/} of the ``daughter'' states; in particular, we find good evidence, in terms of the effective interaction between quasiparticles, that the states $ν= 4/11$ and 4/13 should not be stable.

description: Space and landscape are central terms in the investigation of past societies and their interrelationship with the environment. However, even though these terms are so central, their definition is ambiguous what hinders a successful communication of research results and an open discussion. In this contribution we sketch the historical development of the understanding of space and landscape. Based on this summary we propose to think of these terms inclusively by integrating four different viewpoints on space, i.e. space as container, space as system of relations and connections, space as product of human perception, and space as construct. We employ our integrative viewpoint by developing different research questions for a holistic analysis of the Pre-Pottery Neolithic archaeological site Göbekli Tepe.

description: Using an 185-kg NaI[Tl] array, COHERENT has measured the inclusive electron-neutrino charged-current cross section on ${}^{127}$I with pion decay-at-rest neutrinos produced by the Spallation Neutron Source at Oak Ridge National Laboratory. Iodine is one the heaviest targets for which low-energy ($\leq$ 50 MeV) inelastic neutrino-nucleus processes have been measured, and this is the first measurement of its inclusive cross section. After a five-year detector exposure, COHERENT reports a flux-averaged cross section for electron neutrinos of $9.2^{+2.1}_{-1.8} \times 10^{-40}$ cm$^2$. This corresponds to a value that is $\sim$41% lower than predicted using the MARLEY event generator with a measured Gamow-Teller strength distribution. In addition, the observed visible spectrum from charged-current scattering on $^{127}$I has been measured between 10 and 55 MeV, and the exclusive zero-neutron and one-or-more-neutron emission cross sections are measured to be $5.2^{+3.4}_{-3.1} \times 10^{-40}$ and $2.2^{+3.5}_{-2.2} \times 10^{-40}$ cm$^2$, respectively.

description: This article describes local normal forms of functions in noncommuting variables, up to equivalence generated by isomorphism of noncommutative Jacobi algebras, extending singularity theory in the style of Arnold's commutative local normal forms into the noncommutative realm. This generalisation unveils many new phenomena, including an ADE classification when the Jacobi ring has dimension zero and, by taking suitable limits, a further ADE classification in dimension one. These are natural generalisations of the simple singularities and those with infinite multiplicity in Arnold's classification. We obtain normal forms away from some exceptional Type E cases. Remarkably these normal forms have no continuous parameters, and the key new feature is that the noncommutative world affords larger families.
 This theory has a range of immediate consequences to the birational geometry of 3-folds. The normal forms of dimension zero are the analytic classification of smooth 3-fold flops, and one outcome of NC singularity theory is the first list of all Type D flopping germs, generalising Reid's famous pagoda classification of Type A, with variants covering Type E. The normal forms of dimension one have further applications to divisorial contractions to a curve. In addition, the general techniques also give strong evidence towards new contractibility criteria for rational curves.

description: We obtain a supersymmetric Kaluza-Klein black lens solution in Taub-NUT space in the five-dimensional minimal ungauged supergravity. It is shown that the spacetime has a degenerate horizon with the spatial cross section of the lens space topology L(n,1) and looks like the four-dimensional Minkowski spacetime in the neighborhood of spatial infinity. In contrast to the horizon topology, from a five-dimensional point of view, the spatial infinity has the topology of S^3 rather than the lens space. For this reason, this solution has an asymptotically flat limit. We discuss several properties of such a black lens, in particular, the effect by the compactification of an extra-dimension and some physical differences from the asymptotically flat supersymmetric black lens which has recently been found.

Bulk viscosity of a hot QCD/QGP medium in strong magnetic field within relaxation-time approximation

Year: 2018

description: The bulk viscosity of hot QCD medium has been obtained in the presence of strong magnetic field. The present investigation involves the estimation of the quark damping rate and subsequently the thermal relaxation time for quarks in the presence of magnetic field while realizing the hot QCD medium as an effective Grand-canonical ensemble of effective gluons and quarks-antiquarks. The dominant process in the strong field limit is $1\rightarrow 2$ ($g\rightarrow q \bar{q}$) which contributes to the bulk viscosity in a most significant way. Further, setting up the linearized transport equation in the framework of an effective kinetic theory with hot QCD medium effects and employing the relaxation time approximation, the bulk viscosity has been estimated in lowest Landau level (LLL) and beyond. The temperature dependence of the ratio of the bulk viscosity to entropy density indicates towards its rising behavior near the transition temperature.

description: Hellenistic scholars have been the first to link the geographical description of the known world with a mathematical investigation of the terrestrial sphere. The definition of mathematical concepts devoted to geography and cartography – meridians and parallels, geographical coordinates for example – enabled the development of a specific branch of geographical knowledge. Already in the second century CE, Ptolemy was able to produce maps based on the latitude and the longitude of localities. Compared to more traditional literary geography, mathematical geography did not arise a strong interest among scholars of the Roman and Byzantine periods. This has incited modern historians to impute a global disregard for mathematical sciences to the “Roman geography”.
description: Hellenistische Wissenschaftler haben als Erste die geographische Beschreibung der bekannten Welt mit einer mathematischen Untersuchung der Erde und ihrer Gestalt verbunden. Die Definition von mathematischen Begriffen, die der Geographie und Kartographie gewidmet wurden – wie Meridiane, Parallelkreise oder geographische Koordinaten – ermöglichte die Entwicklung eines spezifischen Zweiges der geographischen Wissenschaft. Aufgrund der Angabe zu Breite und Länge von Orten konnte Ptolemaios schon im 2. Jh. n. Chr. Karten produzieren. Im Vergleich zur traditionelleren literarisch beschreibenden Geographie hat aber mathematische Geographie weniger Erfolg in gelehrten Milieus in römischer und byzantinischer Zeit. Moderne Historiker interpretierten dies als ein Zeichen mangelnden Interesse seitens der „römischen Geographie“ an mathematische Wissenschaft.

description: We study the impact of distinguishability and mixedness -- two fundamental properties of quantum states -- on quantum interference. We show that these can influence the interference of multiple particles in different ways, leading to effects that cannot be observed in the interference of two particles alone. This is demonstrated experimentally by interfering three independent photons in pure and mixed states and observing their different multiphoton interference, despite exhibiting the same two-photon Hong-Ou-Mandel (HOM) interference. Besides its fundamental relevance, our observation has important implications for quantum technologies relying on photon interference.

description: We compute the one-loop divergences in a theory of gravity with Lagrangian of the general form $f(R,R_{μν}R^{μν})$, on an Einstein background. We also establish that the one-loop effective action is invariant under a duality that consists of changing certain parameters in the relation between the metric and the quantum fluctuation field. Finally, we discuss the unimodular version of such a theory and establish its equivalence at one-loop order with the general case.

Publisher: name: arXiv
Year: 1992
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: QCD inequalities are derived for the masses of mesons and baryons containing a single heavy quark using the heavy quark effective field theory. A rigorous lower bound is obtained for the $\barΛ$ parameters of the heavy quark effective theory that parameterize $1/m$ corrections, $\barΛ$ > 237 MeV for mesons, and $\bar Λ> 657$ MeV for baryons. The inequalities on $\barΛ$ imply the inequalities $m_c < 1627$ MeV and $m_b < 5068$ MeV for the mass parameters of the heavy quark effective field theory.

description: The essay proposes the term ‘topopoetics’ in order to explain how cultural meanings, ideas and topoi originating in classical antiquity change and are transformed in and by artefacts. The artefacts under consideration are especially, but not exclusively, textual ones; they tend to unfold their topological dimensions by means of allegorical procedures. The contribution exemplifies the workings of topopoetics in early modernity by discussing central devices in Edmund Spenser’s Faerie Queene, Richard Crashaw’s poetry and the front matter of Kepler’s Rudolphine Tables.
description: Der Beitrag verwendet den heuristischen Begriff ,Topopoetik’, um damit die Art und Weise zu bezeichnen, wie Kunstwerke antike kulturelle Signifikanzen aufnehmen und transformieren. Allegorische Verfahren rücken dabei in den Vordergrund als besonders geeignet zur Kommunikation und Präsentation topologischer Bedeutungen. Topopoetische Leistungen und Funktionen textueller und visueller Artefakte werden an drei Beispielen aus der Frühen Neuzeit erläutert und demonstriert: an Edmund Spensers Faerie Queene, Richard Crashaws metaphysischen Gedichten und an den paratextuellen Materialien, die Keplers Tabulae Rudolphinae vorangestellt sind.
Photon centroids and their subluminal propagation

Subjects: subject: Optics (physics.optics)

description: We examine properties and propagation of the energy-density and photon-probability centroids of electromagnetic wavepackets in free space. In the second-order paraxial approximation, both of these centroids propagate with the same subluminal velocity because of the transverse confinement of the wavepacket and its diffraction. The tiny difference between the energy and probability centroid velocities appears only in the forth order. We consider three types of wavepackets: Gaussian, Bessel, and non-diffracting Bessel. In all these cases, the subluminal propagation is clearly visible in the intensity distributions and can be measured experimentally in both classical-light and single-photon regimes. For Gaussian wavepackets, the half-wavelength delay is accumulated after propagation over about 12 Rayleigh lengths.

Extracting the multi-timescale activity patterns of online financial markets

Subjects: subject: Trading and Market Microstructure (q-fin.TR)

description: Online financial markets can be represented as complex systems where trading dynamics can be captured and characterized at different resolutions and time scales. In this work, we develop a methodology based on non-negative tensor factorization (NTF) aimed at extracting and revealing the multi-timescale trading dynamics governing online financial systems. We demonstrate the advantage of our strategy first using synthetic data, and then on real-world data capturing all interbank transactions (over a million) occurred in an Italian online financial market (e-MID) between 2001 and 2015. Our results demonstrate how NTF can uncover hidden activity patterns that characterize groups of banks exhibiting different trading strategies (normal vs. early vs. flash trading, etc.). We further illustrate how our methodology can reveal "crisis modalities" in trading triggered by endogenous and exogenous system shocks: as an example, we reveal and characterize trading anomalies in the midst of the 2008 financial crisis.

description: In this work we provide analytic and numerical solutions for the Bjorken flow, a standard benchmark in relativistic hydrodynamics providing a simple model for the bulk evolution of matter created in collisions between heavy nuclei. We consider relativistic gases of both massive and massless particles, working in a ( 2 + 1 ) and ( 3 + 1 ) Minkowski space-time coordinate system. The numerical results from a recently developed lattice kinetic scheme show excellent agreement with the analytic solutions.

The Damping and Excitation of Galactic Warps by Dynamical Friction
Creators: name: Nelson, Robert W.
name: Tremaine, Scott
Publisher: name: arXiv
Year: 1994
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We investigate the dynamical interaction of galactic warps with the surrounding dark matter halo, using analytic perturbation theory. A precessing warp induces a density wake in the collisionless dark matter, which acts back on the original warp, transferring energy and angular momentum between the warp and halo (dynamical friction). In most cases dynamical friction damps the warp, but in unusual circumstances (such as a halo that rotates in the same direction as the precession of the warp, or a warp in the equatorial plane of an axisymmetric prolate halo) friction can excite a warp. The damping/excitation time is usually short compared to the Hubble time for realistic systems. Thus most warps cannot be primordial; they must be maintained by some ongoing excitation mechanism.

Algebraic cycles and functorial lifts from $G_2$ to $\mathrm{PGSp}_6$

description: We study instances of Beilinson-Tate conjectures for automorphic representations of $\mathrm{PGSp}_6$ whose Spin $L$-function has a pole at $s=1$. We construct algebraic cycles of codimension three in the Siegel-Shimura variety of dimension six and we relate its regulator to the residue at $s=1$ of the $L$-function of certain cuspidal forms of $\mathrm{PGSp}_6$. Using the exceptional theta correspondence between the split group of type $G_2$ and $\mathrm{PGSp}_6$ and assuming the non-vanishing of a certain archimedean integral, this allows us to confirm a conjecture of Gross and Savin on rank $7$ motives of type $G_2$.
