description: We explore how to improve the hybrid model description of the particles originating from the wake that a jet produced in a heavy ion collision leaves in the droplet of quark-gluon plasma (QGP) through which it propagates, using linearized hydrodynamics on a background Bjorken flow. Jet energy and momentum loss described by the hybrid model become currents sourcing linearized hydrodynamics. By solving the linearized hydrodynamic equations numerically, we investigate the development of the wake in the dynamically evolving droplet of QGP, study the effect of viscosity, scrutinize energy-momentum conservation, and check the validity of the linear approximation. We find that linearized hydrodynamics works better in the viscous case because diffusive modes damp the energy-momentum perturbation produced by the jet. We calculate the distribution of particles produced from the jet wake by using the Cooper-Frye prescription and find that both the transverse momentum spectrum and the distribution of particles in azimuthal angle are similar in shape in linearized hydrodynamics and in the hybrid model. Their normalizations are different because the momentum-rapidity distribution in the linearized hydrodynamics analysis is more spread out, due to sound modes. Since the Bjorken flow has no transverse expansion, we explore the effect of transverse flow by using local boosts to add it into the Cooper-Frye formula. After including the effects of transverse flow in this way, the transverse momentum spectrum becomes harder: more particles with transverse momenta bigger than $2$ GeV are produced than in the hybrid model. Although we defer implementing this analysis in a jet Monte Carlo, as would be needed to make quantitative comparisons to data, we gain a qualitative sense of how the jet wake may modify jet observables by computing proxies for two example observables: the lost energy recovered in a cone of varying open angle, and the fragmentation function. We find that linearized hydrodynamics with transverse flow effects added improves the description of the jet wake in the hybrid model in just the way that comparison to data indicates is needed. Our study illuminates a path to improving the description of the wake in the hybrid model, highlighting the need to take into account the effects of both transverse flow and the broadening of the energy-momentum perturbation in spacetime rapidity on particle production.

description: The objective of this research was to analyze the demand patterns of Hispanic households for meats in comparison with other ethnic groups using data from the 1998 Consumer Expenditure Survey. A system of demand equations of the LinQuad form were estimated for ten meat products using an incomplete system of censored equations. Hispanic households showed a clear preference for beef. Price, income and household size elasticities were estimated for each meat product by ethnic group. The demand for ground beef was the most income inelastic product regardless of ethnicity. Household size had a positive effect on the probability of consuming a particular meat product but a negative effect on actual item expenditures.

description: We present a photometric analysis of the rich star cluster population in the tidal tails of NGC 6872. We find star clusters with ages between 1 - 100 Myr distributed in the tidal tails, while the tails themselves have an age of less than 150 Myr. Most of the young massive ($10^{4} \le M/M_{\odot} \le 10^{7}$) clusters are found in the outer regions of the galactic disk or the tidal tails. The mass distribution of the cluster population can be well described by power-law of the form $N(m) \propto m^{-α}$, where $α= 1.85 \pm 0.11$, in very good agreement with other young cluster populations found in a variety of different environments. We estimate the star formation rate for three separate regions of the galaxy, and find that the eastern tail is forming stars at $\sim 2$ times the rate of the western tail and $\sim 5$ times the rate of the main body of the galaxy. By comparing our observations with published N-body models of the fate of material in tidal tails in a galaxy cluster potential, we see that many of these young clusters will be lost into the intergalactic medium. We speculate that this mechanism may also be at work in larger galaxy clusters such as Fornax, and suggest that the so-called ultra-compact dwarf galaxies could be the most massive star clusters that have formed in the tidal tails of an ancient galactic merger.

description: We study holographically the zero and finite temperature behavior of the potential energy and holographic subregion complexity corresponding to a probe meson in a non-conformal model. We observe that in zero and low temperature non-conformality has a decreasing effect on the dimensionless meson potential energy. However, non-conformal corrections increase absolute value of the dimensionless holographic subregion complexity in both zero and finite temperature which means the non-conformal state needs less information to be specified. In other words, considering the effect of non-conformality, the less bounded meson state needs less information to be specified. In low temperature limits, thermal corrections decrease meson potential energy and do not have a specific effect on holographic subregion complexity. We find that in the vicinity of the phase transition, the zero temperature meson state is more favorable than the finite temperature state, from the holographic subregion complexity point of view.

The tetrahedron transformation is then identified with a sequence of four mutations. As an application of the new formalism we show how to construct integrable system with spectral curve with arbitrary symmetric Newton polygon. Finally, we embed this integrable system into double Bruhat cell of a Poisson-Lie group, show how triangular decomposition can be used to extend our approach to general non-symmetric Newton polygons, and prove Lemma, which classifies conjugacy classes in double affine Weyl groups of $A$-type by Newton polygons.

description: We perform the first study of lattice QCD with overlap fermions at finite temperature $T$ and chemical potential $μ$. We start from the Taylor expanded overlap fermion action, and derive in the strong coupling limit the effective free energy by mean field approximation. On the ($μ,T$) plane and in the chiral limit, there is a tricritical point, separating the second order chiral phase transition line at small $μ$ and large $T$, and first order chiral phase transition line at large $μ$ and small $T$.
The re-appropriation and transformation of a national symbol: Wilhelm Tell 1789-1895
Creators: name: Tschan, Reto
Publisher: name: University of British Columbia
Year: 2009

description: Wilhelm Tell, the rugged mountain peasant armed with his crossbow, is the quintessential symbol of Switzerland. He personifies both Switzerland's ancient liberty and the concept of an armed Swiss citizenry. His likeness is everywhere in modern Switzerland and his symbolic value is clearly understood: patriotism, independence, self-defense. Tell's status as the preeminent national symbol of Switzerland is, however, relatively new. While enlightened reformers of the eighteenth century cultivated the image of Tell for patriotic purposes, it was, in fact, during the French occupation of Switzerland that Wilhelm Tell emerged as a national symbol. French revolutionary propaganda idolized Tell's act of tyrannicide, justified the 1798 invasion of Switzerland in Tell's name, and made Tell the official symbol of the Helvetic Republic. Tell's intimate association with the French alienated many Swiss from their traditional hero. During the course of the nineteenth century, however, Tell was re-appropriated and rehabilitated as a suitable national symbol. This paper seeks to understand how this process occurred and how the figurative and symbolic value of Tell was transformed between ancien regime and late nineteenth-century Switzerland. While Tell's character is generally treated as one-dimensional, his figurative and symbolic form was modified by various pressures and influences, including primarily his French appropriation, Friedrich Schiller's play, and Swiss historiography. By examining Tell's various symbolic incarnations, this paper seeks to understand the origins of his character and form as they were ultimately monumentalized in Richard Kissling's Telldenkmal of 1895. Though Tell's choice is often treated as a foregone conclusion, this paper is interested in how Tell came to achieve his final symbolic form and how he came to establish himself as the predominant national symbol for Switzerland.

description: Within the framework of metric-affine gravity (MAG, metric and an independent linear connection constitute spacetime), we find, for a specific gravitational Lagrangian and by using {\it prolongation} techniques, a stationary axially symmetric exact solution of the vacuum field equations. This black hole solution embodies a Kerr-deSitter metric and the post-Riemannian structures of torsion and nonmetricity. The solution is characterized by mass, angular momentum, and shear charge, the latter of which is a measure for violating Lorentz invariance.

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Certain power-counting non-renormalizable theories, including the most general self-interacting scalar fields in four and three dimensions and fermions in two dimensions, have a simplified renormalization structure. For example, in four-dimensional scalar theories, 2n derivatives of the fields, n>1, do not appear before the nth loop. A new kind of expansion can be defined to treat functions of the fields (but not of their derivatives) non-perturbatively. I study the conditions under which these theories can be consistently renormalized with a reduced, eventually finite, set of independent couplings. I find that in common models the number of couplings sporadically grows together with the order of the expansion, but the growth is slow and a reasonably small number of couplings is sufficient to make predictions up to very high orders. Various examples are solved explicitly at one and two loops.

description: We analyze the stationary configuration of a thin axisymmetric stellar accretion disk, neglecting non-linear terms in the plasma poloidal velocity components. We set up the Grad-Shafranov equation for the system, including the plasma differential rotation (according to the so-called co-rotation theorem). Then, we study the small scale backreaction of the disk to the central body magnetic field and we calculate the resulting radial infalling velocity. We show that the small scale radial oscillation of the perturbed magnetic surface is associated to the emergence of relevant toroidal current densities, able to balance the Ohm law even in the presence of quasi-ideal values of the plasma resistivity. The contribution to the infalling velocity of the averaged backreaction contrasts accretion, but it remains negligible as far as the induced magnetic field is small compared to that of the central body.

description: Entity matching is the problem of identifying which records refer to the same real-world entity. It has been actively researched for decades, and a variety of different approaches have been developed. Even today, it remains a challenging problem, and there is still generous room for improvement. In recent years we have seen new methods based upon deep learning techniques for natural language processing emerge. In this survey, we present how neural networks have been used for entity matching. Specifically, we identify which steps of the entity matching process existing work have targeted using neural networks, and provide an overview of the different techniques used at each step. We also discuss contributions from deep learning in entity matching compared to traditional methods, and propose a taxonomy of deep neural networks for entity matching.

description: Using semiclassical periodic orbit theory for a chaotic system in a weak magnetic field, we obtain the form factor predicted by Pandey and Mehta's two matrix model up to the third order. The third order contribution has a peculiar term which exists only in the intermediate crossover domain between the GOE (Gaussian Orthogonal Ensemble) and the GUE (Gaussian Unitary Ensemble) universality classes. The exact expression is obtained by taking account of the contribution from encounter regions where orbit loops are connected.

Precursor effects of the superconducting state caused by d-wave phase-fluctuations above Tc

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: One of the hallmarks of high-temperature superconductors is a pseudogap regime appearing in the underdoped cuprates above the superconducting transition temperature Tc. The pseudogap continously develops out of the superconducting gap. In addition, high-frequency conductivity experiments show a superconducting scaling of the optical response in the pseudogap regime, pointing towards a superconducting origin of the pseudogap. The phase-fluctuation vortex scenario is further supported by the measurement of an unusually large Nernst signal above Tc and the recently observed field-enhanced diamagnetism which scales with the Nernst signal. In this paper, we use a simple phenomenological model to calculate the paraconductivity and magnetic response caused by phase fluctuations of the superconducting order parameter above Tc. Our results are in agreement with experiments such as the superconducting scaling of the optical response and the spin (or Pauli) susceptibility, and further strengthen the idea of a phase-fluctuation origin of the pseudogap.

description: The complex dynamics of an increasing number of systems is attributed to the emergence of a rugged energy landscape with an exponential number of metastable states. To develop this picture into a predictive dynamical theory I discuss how to compute the exponentially small probability of a jump from one metastable state to another. This is expressed as a path integral that can be evaluated by saddle-point methods in mean-field models, leading to a boundary value problem. The resulting dynamical equations are solved numerically by means of a Newton-Krylov algorithm in the paradigmatic spherical $p$-spin glass model that is invoked in diverse contexts from supercooled liquids to machine-learning algorithms. I discuss the solutions in the asymptotic regime of large times and the physical implications on the nature of the ergodicity-restoring processes.

description: We present various 4d $\mathcal{N}=1$ theories enjoying IR global symmetry enhancement. The models we consider have the $USp(2n)$ gauge group, 8 fundamental, one antisymmetric chirals and various numbers of gauge singlets. By suitably turning on superpotential deformations involving the singlets which break part of the UV symmetry we flow to SCFTs with $E_6$, $SO(10)$, $SO(9)$, $SO(8)$ and $F_4$ IR global symmetry. We explain these patterns of symmetry enhancement following two arguments due to Razamat, Sela and Zafrir. The first one involves the study of the relations satisfied by marginal operators, while the second one relies on the existence of self-duality frames.

description: We investigate the classical stability of non-supersymmetric Freund-Rubin compactifications of Type IIB string theory on a product of three-dimensional Einstein spaces A_3 x B_3 with both NS-NS and R-R three-form fluxes turned on through A_3 and B_3, and a zero axion. This results in a three parameter family of AdS_4 vacua, with localized sources such as anti-three-branes or orientifold planes required to cancel the R-R four-form tadpole. We scan the entire space of such solutions for perturbative stability and find that anti-three-branes are unstable to a Jeans-like instability. For orientifold compactifications, we derive a precise criterion which the three dimensional Einstein spaces have to satisfy in order to be stable.

description: Slides used for a breakout session at the upcoming UKSG Annual Conference 2021, April 12-14 2021.

Abstract:In the absence of funds for 'gold' open access, publishers may allow universities to share the author's manuscript on a 'green' basis, with or without an embargo. In the UK, the former means the work can be openly accessed typically after a period of 12-24 months. Such time gives publishers opportunity to build revenue, but creates inequalities. Firstly, there is a division between those who can afford a fee or can access a library subscription to benefit from the research and those that cannot; but there is also a divide between universities that have funds to pay publishing charges and less research intensive institutions that have no such fund.

This case study considers journal articles published by Edge Hill University in 2019. Originally a teacher training college, the University received taught degree-awarding powers its university title in 2006, followed by Research Degree Awarding Powers in 2008. A key finding is that embargoes mean certain kinds of research articles can be 'locked down' for longer. For instance, educational journal articles were found to be held back from public access for more than twice the time compared with health research. This is driven by disseminating research through publishers who make consistent use of embargoes.

As a result, the consumers of Edge Hill's education research (e.g. schools, teachers) may need to wait longer to use it. This can potentially affect their ability to use research to innovate, enhance practice, or respond to societal challenges.

description: We discuss shape (Pomeranchuk) instabilities of the Fermi surface of a two-dimensional Fermi system using bosonization. We consider in detail the quantum critical behavior of the transition of a two dimensional Fermi fluid to a nematic state which breaks spontaneously the rotational invariance of the Fermi liquid. We show that higher dimensional bosonization reproduces the quantum critical behavior expected from the Hertz-Millis analysis, and verify that this theory has dynamic critical exponent $z=3$. Going beyond this framework, we study the behavior of the fermion degrees of freedom directly, and show that at quantum criticality as well as in the the quantum nematic phase (except along a set of measure zero of symmetry-dictated directions) the quasi-particles of the normal Fermi liquid are generally wiped out. Instead, they exhibit short ranged spatial correlations that decay faster than any power-law, with the law $|x|^{-1} \exp(-\textrm{const.} |x|^{1/3})$ and we verify explicitely the vanishing of the fermion residue utilizing this expression. In contrast, the fermion auto-correlation function has the behavior $|t|^{-1} \exp(-{\rm const}. |t|^{-2/3})$. In this regime we also find that, at low frequency, the single-particle fermion density-of-states behaves as $N^*(ω)=N^*(0)+ B ω^{2/3} \logω+...$, where $N^*(0)$ is larger than the free Fermi value, N(0), and $B$ is a constant. These results confirm the non-Fermi liquid nature of both the quantum critical theory and of the nematic phase.

Mismatch negativity cortical event-related potential measures of cross-linguistic phoneme perception
Creators: name: Tsui, Vicki Chi Ki
Publisher: name: University of British Columbia
Year: 2009

description: It is a well-established fact that infants are born with the ability to discriminate a universal set of phonetic categories. However, the ability to consciously perceive phonetic contrasts which are not relevant in one's native language gradually decreases within the first year of life. The objective of this investigation is to determine whether non-native category changes are still recognized by adults at early levels of auditory processing even though they find it difficult, or impossible, to discriminate them behaviourally. Electrophysiological and behavioural responses to native (/ba/ vs. /da/) and non-native contrasts (/da/ vs. /Da/) were obtained from native English listeners. The component of the event-related potential (ERP) of particular interest is the mismatch negativity (MMN), generated in the auditory cortex. The MMN is a waveform difference which occurs, independent of attention, in response to a discriminable change in a repeated sound stimulus. Therefore, if the ability to perceive the non-native category change is preserved at the level of the primary auditory cortex, we would expect to find an MMN response to that change. For the passive ERP measures, stimuli were presented in an oddball paradigm, with conditions counterbalanced for order. The behavioural condition consisted of a forced-choice task in which participants were presented with various stimulus pairs and asked to decide whether the stimuli within the pair were "same" or "different". Behavioural results confirm that the majority of the English listeners could not discriminate the non-native category change. Performance in the native category was significantly better. Surprisingly, ERP results not only indicate that there is a distinct MMN in response to the non-native category change, but that this response actually tends to be larger in amplitude than the response to the native category change. The order of presentation of the stimuli also has a significant effect on the amplitude of the MMN. The MMN response appears to be stronger when /da/ is the standard stimuli and when /Da/ is the deviant. It is clear from these results that the auditory cortex is indeed able to recognize non-native phonetic category changes even when they are not consciously perceived by the listener. These findings support the theory that the change in categorical perceptual ability from infancy to adulthood involves a functional reorganization rather than a permanent loss of ability.

description: We study anomalous dimensions of (super)conformal Wilson operators at weak and strong coupling making use of the integrability symmetry on both sides of the gauge/string correspondence and elucidate the origin of their single-logarithmic behavior for long operators/strings in the limit of large Lorentz spin. On the gauge theory side, we apply the method of the Baxter Q-operator to identify different scaling regimes in the anomalous dimensions in integrable sectors of (supersymmetric) Yang-Mills theory to one-loop order and determine the values of the Lorentz spin at which the logarithmic scaling sets in. We demonstrate that the conventional semiclassical approach based on the analysis of the distribution of Bethe roots breaks down in this domain. We work out an asymptotic expression for the anomalous dimensions which is valid throughout the entire region of variation of the Lorentz spin. On the string theory side, the logarithmic scaling occurs when two most distant points of the folded spinning string approach the boundary of the AdS space. In terms of the spectral curve for the classical string sigma model, the same configuration is described by an elliptic curve with two branching points approaching values determined by the square root of the 't Hooft coupling constant. As a result, the anomalous dimensions cease to obey the BMN scaling and scale logarithmically with the Lorentz spin.

description: The Hubble parameter is one of the central parameters in modern cosmology, which describes the present expansion rate of the universe. Their values inferred from the late-time observations are systematically higher than those from the early-time measurements by about $10\%$. To come to a robust conclusion, independent probes with accuracy at percent levels are crucial. Gravitational waves from compact binary coalescence events can be formulated into the standard siren approach to provide an independent Hubble parameter measurement. The future space-borne gravitational wave observatory network, such as the LISA-Taiji network, will be able to measure the gravitational wave signals in the Millihertz bands with unprecedented accuracy. By including several statistical and instrumental noises, we show that within 5 years operation time, the LISA-Taiji network is able to constrain the Hubble parameter within $1\%$ accuracy, and possibly beats the scatters down to $0.5\%$ or even better.

description: Cell-free (CF) massive multiple-input-multiple-output (mMIMO) deployments are usually investigated with half-duplex nodes and high-capacity fronthaul links. To leverage the possible gains in throughput and energy efficiency (EE) of full-duplex (FD) communications, we consider a FD CF mMIMO system with practical limited-capacity fronthaul links. We derive closed-form spectral efficiency (SE) lower bounds for this system with maximum-ratio combining/maximum-ratio transmission processing and optimal uniform quantization. We then optimize the weighted sum EE (WSEE) via downlink and uplink power control by using a {two-layered} approach: the first layer formulates the optimization as a generalized convex program, while the second layer solves the optimization decentrally using alternating direction method of multipliers. We analytically show that the proposed two-layered formulation yields a Karush-Kuhn-Tucker point of the original WSEE optimization. We numerically show the influence of weights on the individual EE of the users, which demonstrates the utility of WSEE metric to incorporate heterogeneous EE requirements of users. We show that the low fronthaul capacity reduces the number of users each AP can support, and the cell-free system, consequently, becomes user-centric.

description: A stochastic production frontier model with technical inefficiency effects is estimated on a representative sample of Ukrainian state and collective grain-producing farms. Technical efficiency declined from 1989 to 1992. More experienced managers were found to be more productive, with the effect of experience diminishing with age. We found that on-farm provision of production infrastructure was associated with higher efficiency, a result supporting the hypothesis that disorganization causes output to decline in transition economies.

Simulation of high speed flows
Creators: name: Kianvashrad, Nadia
Publisher: name: No Publisher Supplied

description: There is a reinterest in hypersonic flow. There are several programs all around the world to produce hypersonic aircraft. Computational fluid dynamics (CFD) is an essential tool for high speed aerodynamics. However, it is still under investigation that how reliable is this tool especially at high stagnation enthalpies at high speed flows where non-equilibrium effects are important. For assessment of the CFD capability in the prediction of the aerothermodynamic loading (surface pressure and surface heat transfer) on a hypersonic vehicle, three sample experiments are examined in this dissertation. The models include a hollow cylinder flare, a double cone, and a hemisphere at Mach number range of 10.9 to 14.6. The laminar shock wave boundary layer interaction is investigated at high enthalpy ranges of 9.65 to 21.85 MJ/kg. It is shown that the formation of a supersonic jet as a result of the interaction of the shock waves prevented the highly dissociated gas to reach to the surface and thus the thermally perfect gas model has the best prediction of surface pressure and heat transfer. For hollow cylinder flare, the shock wave boundary layer interaction is weak and therefore, the effect of non-equilibrium modeling is negligible. The Edney III type shock-shock interaction is studied over a hemisphere at low enthalpy of 2.1 MJ/kg. Edney III interaction can create a region of high pressure and heat transfer over the surface. Therefore, accurate prediction of this phenomenon is essential. The study in this dissertation shows that the interaction is very sensitive to the location of the interaction of the impinging shock and the bow shock. This can change even the flow regime from laminar to turbulent. Another challenge facing scientists in producing a hypersonic vehicle is how to rapidly maneuver the vehicle. The common controlling methods are too slow and during their actuation time, the vehicle moves several times its length. One option is to use energy discharge to change the flow structure around the body. This changes the pressure distribution over the body which can create pitching moments for steering the vehicle. Drag reduction is also another benefit that can achieve from energy deposition. If the energy discharge is on the axis of symmetry of the body, only drag reduction is acquired; however, off axis energy discharge provides drag reduction, side force and thus pitching moment. This dissertation has shown that the drag reduction and pitching moment depend on the amount of energy deposited, the location of the discharge, and the shape of the body.

description: We present an update of the General-relativistic multigrid numerical (Gmunu) code, a parallelized, multi-dimensional curvilinear, general relativistic magnetohydrodynamics code with an efficient non-linear cell-centred multigrid (CCMG) elliptic solver, which is fully coupled with an efficient block-based adaptive mesh refinement modules. Currently, Gmunu is able to solve the elliptic metric equations in the conformally flat condition (CFC) approximation with the multigrid approach and the equations of ideal general-relativistic magnetohydrodynamics by means of high-resolution shock-capturing finite volume method with reference-metric formularise multi-dimensionally in cartesian, cylindrical or spherical geometries. To guarantee the absence of magnetic monopoles during the evolution, we have developed an elliptical divergence cleaning method by using multigrid solver. In this paper, we present the methodology, full evolution equations and implementation details of our code Gmunu and its properties and performance in some benchmarking and challenging relativistic magnetohydrodynamics problems.
