description: For a finite connected simple graph, the Terwilliger algebra is a matrix algebra generated by the adjacency matrix and idempotents corresponding to the distance partition with respect to a fixed vertex. We will consider algebras defined by two other partitions and the centralizer algebra of the stabilizer of the fixed vertex in the automorphism group of the graph. We will give some methods to compute such algebras and examples for various graphs.

description: Pebble games are popular models for analyzing time-space trade-offs. In particular, the reversible pebble game is often applied in quantum algorithms like Grover's search to efficiently simulate classical computation on inputs in superposition. However, the reversible pebble game cannot harness the additional computational power granted by irreversible intermediate measurements. The spooky pebble game, which models interleaved measurements and adaptive phase corrections, reduces the number of qubits beyond what reversible approaches can achieve. While the spooky pebble game does not reduce the total space (bits plus qubits) complexity of the simulation, it reduces the amount of space that must be stored in qubits. We prove asymptotically tight trade-offs for the spooky pebble game on a line with any pebble bound, giving a tight time-qubit tradeoff for simulating arbitrary classical sequential computation with the spooky pebble game. For example, for all $ε\in (0,1]$, any classical computation requiring time $T$ and space $S$ can be implemented on a quantum computer using only $O(T/ ε)$ gates and $O(T^εS^{1-ε})$ qubits. This improves on the best known bound for the reversible pebble game with that number of qubits, which uses $O(2^{1/ε} T)$ gates.
 We also consider the spooky pebble game on more general directed acyclic graphs (DAGs), capturing fine-grained data dependency in computation. We show that for an arbitrary DAG even approximating the number of required pebbles in the spooky pebble game is PSPACE-hard. Despite this, we are able to construct a time-efficient strategy for pebbling binary trees that uses the minimum number of pebbles.

description: Non-equilibrium steady state (NESS) conditions induced by DC current can alter the physical properties of strongly correlated electron systems (SCES). In this regard, it was recently shown that DC current can trigger novel electronic states, such as current-induced diamagnetism, which cannot be realized in equilibrium conditions. However, reversible control of diamagnetism has not been achieved yet. Here, we demonstrate reversible in situ control between a Mott insulating state and a diamagnetic semimetal-like state by DC current in the Ti-substituted bilayer ruthenate Ca$_3$(Ru$_{1-x}$Ti$_x$)$_2$O$_7$ ($x=0.5$%). By performing simultaneous magnetic and resistive measurements, we map out the temperature vs current-density phase diagram in the NESS of this material. The present results open up the possibility of creating novel electronic states in a variety of SCES under DC current.

description: We propose a new representation of $k$-partite, $k$-uniform hypergraphs, that is, a hypergraph with a partition of vertices into $k$ parts such that each hyperedge contains exactly one vertex of each type; we call them $k$-hypergraphs for short. Given positive integers $\ell, d$, and $k$ with $\ell\leq d-1$ and $k={d\choose\ell}$, any finite set $P$ of points in $\mathbb{R}^d$ represents a $k$-hypergraph $G_P$ as follows. Each point in $P$ is covered by $k$ many axis-aligned affine $\ell$-dimensional subspaces of $\mathbb{R}^d$, which we call $\ell$-subspaces for brevity and which form the vertex set of $G_P$. We interpret each point in $P$ as a hyperedge of $G_P$ that contains each of the covering $\ell$-subspaces as a vertex. The class of \emph{$(d,\ell)$-hypergraphs} is the class of $k$-hypergraphs that can be represented in this way. The resulting classes of hypergraphs are fairly rich: Every $k$-hypergraph is a $(k,k-1)$-hypergraph. On the other hand, $(d,\ell)$-hypergraphs form a proper subclass of the class of all $k$-hypergraphs for $\ell

description: Rotational grazing provides potential private and social benefits. However, the average adoption rate among ranchers is just over 30 percent in the United States. Peer effects are increasingly recognized as an important driver of technology adoption. We develop a model to identify how peer networking affects ranchers’ adoption decision of grazing practices, and also the impacts of subsidies. With farm-level survey data, we apply a simultaneous-equations model to take account of endogeneity issues with peer effects that are measured as the number of adopters a rancher knows or the extent of adoption in a rancher’s neighborhood. Empirical analysis provides evidence that there are significant peer effects in the adoption of rotational grazing. This implies that incentive policies will have multiplier effects in the long run on adoption through the channel of peer networking.

description: We derive correlations between X-ray temperature, luminosity, and gas mass for a sample of 22 distant, z>0.4, galaxy clusters observed with Chandra. We detect evolution in all three correlations between z>0.4 and the present epoch. In particular, in the Omega=0.3, Lambda=0.7 cosmology, the luminosity corresponding to a fixed temperature scales approximately as (1+z)**(1.5+-0.3); the gas mass for a fixed luminosity scales as (1+z)**(-1.8+-0.4); and the gas mass for a fixed temperature scales as (1+z)**(-0.5+-0.4) (all uncertainties are 90% confidence). We briefly discuss the implication of these results for cluster evolution models.

description: In this paper, we approach the problem of semantic search by framing the search task as paraphrase span detection, i.e. given a segment of text as a query phrase, the task is to identify its paraphrase in a given document, the same modelling setup as typically used in extractive question answering. On the Turku Paraphrase Corpus of 100,000 manually extracted Finnish paraphrase pairs including their original document context, we find that our paraphrase span detection model outperforms two strong retrieval baselines (lexical similarity and BERT sentence embeddings) by 31.9pp and 22.4pp respectively in terms of exact match, and by 22.3pp and 12.9pp in terms of token-level F-score. This demonstrates a strong advantage of modelling the task in terms of span retrieval, rather than sentence similarity. Additionally, we introduce a method for creating artificial paraphrase data through back-translation, suitable for languages where manually annotated paraphrase resources for training the span detection model are not available.

Methodology for replacing indirect measurements with direct measurements

Year: 2019
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In quantum computing, the indirect measurement of unitary operators such as the Hadamard test plays a significant role in many algorithms. However, in certain cases, the indirect measurement can be reduced to the direct measurement, where a quantum state is destructively measured. Here we investigate in what cases such a replacement is possible and develop a general methodology for trading an indirect measurement with sequential direct measurements. The results can be applied to construct quantum circuits to evaluate the analytical gradient, metric tensor, Hessian, and even higher order derivatives of a parametrized quantum state. Also, we propose a new method to measure the out-of-time-order correlator based on the presented protocol. Our protocols can reduce the depth of the quantum circuit significantly by making the controlled operation unnecessary and hence are suitable for quantum-classical hybrid algorithms on near-term quantum computers.

description: Cartan's uniqueness theorem does not hold in general for CR mappings, but it does hold under certain conditions guaranteeing extendibility of CR functions to a fixed neighborhood. These conditions can be defined naturally for a wide class of sets such as local real-analytic subvarieties or subanalytic sets, not just submanifolds. Suppose that $V$ is a locally connected and locally closed subset of ${\mathbb{C}}^n$ such that the hull constructed by contracting analytic discs close to arbitrarily small neighborhoods of a point always contains the point in the interior. Then restrictions of holomorphic functions uniquely extend to a fixed neighborhood of the point. Using this extension, we obtain a version of Cartan's uniqueness theorem for such sets. When $V$ is a real-analytic subvariety, we can generalize the concept of infinitesimal CR automorphism and also prove an analogue of the theorem. As an application of these two results we show that, for circular subvarieties satisfying the condition, the only automorphisms, CR or infinitesimal, are linear.

description: Solar eruptions occurring at different places within a relatively short time interval are considered to be sympathetic. However, it is difficult to determine whether there exists a cause and effect between them. Here we study a failed and a successful filament eruption following an X1.8-class flare on 2014 December 20, in which slipping-like magnetic reconnections serve as a key causal link among the eruptions. Reconnection signatures and effects are: at both sides of the filament experiencing the failed eruption, serpentine ribbons extend along chromospheric network to move away from the filament, while a hot loop apparently grows above it; at the filament undergoing the successful eruption, overlying cold loops contract, while coronal dimming appears at both sides even before the filament eruption. These effects are understood by reconnections continually transforming magnetic fluxes overlying one filament to the other, which adjusts how the magnetic field decays with increasing height above the filaments in opposite trends, therefore either strengthening or weakening the magnetic confinement of each filament.

description: We present a detailed study of the partial rest-optical ($λ_{\mathrm{obs}} \approx 3600-5600\,$Å) spectra of $N = 328$ star-forming galaxies at $0.6 < z < 1.0$ from the Large Early Galaxy Astrophysics Census (LEGA-C). We compare this sample with low-redshift ($z \sim 0$) galaxies from the Sloan Digital Sky Survey (SDSS), intermediate-redshift ($z \sim 1.6$) galaxies from the Fiber Multi-Object Spectrograph (FMOS)-COSMOS Survey, and high-redshift ($z \sim 2$) galaxies from the Keck Baryonic Structure Survey (KBSS). At a lookback time of $6-8\ \mathrm{Gyr}$, galaxies with stellar masses $\mathrm{log}(\mathrm{M_{\ast}/M_{\odot}}) > 10.25$ appear remarkably similar to $z \sim 0$ galaxies in terms of their nebular excitation, as measured using $\mathrm{[O\,III]}\lambda5008 / \mathrm{H}β$. There is some evidence that $0.6 < z < 1.0$ galaxies with lower $\mathrm{M_{\ast}}$ have higher $\mathrm{[O\,III]}\lambda5008 / \mathrm{H}β$ than $z \sim 0$ galaxies and are more similar to less evolved $z \sim 1.6$ and $z \sim 2$ galaxies, which are offset from the $z \sim 0$ locus at all $\mathrm{M_{\ast}}$. We explore the impact selection effects, contributions from active galactic nuclei, and variations in physical conditions (ionization parameter and gas-phase oxygen abundance) have on the apparent distribution of $\mathrm{[O\,III]}\lambda5008 / \mathrm{H}β$ and find somewhat higher ionization and lower enrichment in $0.6 < z < 1.0$ galaxies with lower $\mathrm{M_{\ast}}$ relative to $z \sim 0$ galaxies. We use new near-infrared spectroscopic observations of $N = 53$ LEGA-C galaxies to investigate other probes of enrichment and excitation. Our analysis demonstrates the importance of obtaining complete rest-optical spectra of galaxies in order to disentangle these effects.

description: We have developed a numerical code to study the evolution of self-gravitating matter in dynamic black hole axisymmetric spacetimes in general relativity. The matter fields are evolved with a high-resolution shock-capturing scheme that uses the characteristic information of the general relativistic hydrodynamic equations to build up a linearized Riemann solver. The spacetime is evolved with an axisymmetric ADM code designed to evolve a wormhole in full general relativity. We discuss the numerical and algorithmic issues related to the effective coupling of the hydrodynamical and spacetime pieces of the code, as well as the numerical methods and gauge conditions we use to evolve such spacetimes. The code has been put through a series of tests that verify that it functions correctly. Particularly, we develop and describe a new set of testbed calculations and techniques designed to handle dynamically sliced, self-gravitating matter flows on black holes, and subject the code to these tests. We make some studies of the spherical and axisymmetric accretion onto a dynamic black hole, the fully dynamical evolution of imploding shells of dust with a black hole, the evolution of matter in rotating spacetimes, the gravitational radiation induced by the presence of the matter fields and the behavior of apparent horizons through the evolution.

description: We present optical broadband (B and R) observations of the Seyfert 1 nucleus NGC 3516, obtained at Wise Observatory from March 1997 to March 2002, contemporaneously with X-ray 2-10 keV measurements with RXTE. With these data we increase the temporal baseline of this dataset to 5 years, more than triple to the coverage we have previously presented for this object. Analysis of the new data does not confirm the 100-day lag of X-ray behind optical variations, tentatively reported in our previous work. Indeed, excluding the first year's data, which drive the previous result, there is no significant correlation at any lag between the X-ray and optical bands. We also find no correlation at any lag between optical flux and various X-ray hardness ratios. We conclude that the close relation observed between the bands during the first year of our program was either a fluke, or perhaps the result of the exceptionally bright state of NGC 3516 in 1997, to which it has yet to return. Reviewing the results of published joint X-ray and UV/optical Seyfert monitoring programs, we speculate that there are at least two components or mechanisms contributing to the X-ray continuum emission up to 10 keV: a soft component that is correlated with UV/optical variations on timescales >1 day, and whose presence can be detected when the source is observed at low enough energies (about 1 keV), is unabsorbed, or is in a sufficiently bright phase; and a hard component whose variations are uncorrelated with the UV/optical.

description: Spin textures with nontrivial topology hold great promise in future spintronics applications since they are robust against local deformations. The meron, as one of such spin textures, is widely believed to appear in pairs due to its topological equivalence to a half skyrmion. Motivated by recent progresses in high-spin Kitaev magnets, here we investigate numerically a classical Kitaev-$Γ$ model with a single-ion anisotropy. An exotic spin texture including three merons is discovered. Such a state features a peculiar property with an odd number of merons in one magnetic unit cell and it can induce the topological Hall effect.Therefore, these merons cannot be dissociated from skyrmions as reported in the literature and a general mechanism for such a deconfinement phenomenon calls for further studies. Our work demonstrates that high-spin Kitaev magnets can host robust unconventional spin textures and thus they offer a versatile platform not only for exploring exotic states in spintronics but also for understanding the deconfinement mechanism in the condensed-matter physics and the field theory.

description: The theory of abstract convexity, also known as convexity without linearity, is an extension of the classical convex analysis. There are a number of remarkable results, mostly concerning duality, and some numerical methods, however, this area has not found many practical applications yet. In this paper we study the application of abstract convexity to function approximation. Another important research direction addressed in this paper is the connection with the so-called axiomatic convexity.

Mechanical Choreographies of an "Evolutionary Alchemist": Stelarc's Techno Body and Multimedia Performance

Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2003

description: Ιn this paper, attention is paid tο the mixture of revulsion and appeal that Stelarc's body performances evoke. Their reliance on the staging of numerous events of penetration, piercing and suspension, facilitated by electronic and virtual technologies, underlines the flexibility and endurance of the human body form. However, the limitations that such practices impose on bodies and technologies alike highlight the ambivalence that such performative acts generate. Ιn the present reading of Stelarc's multimedia projects, an evaluation and criticism of the technological practices he adopts for the construction of a technologically and biologically augmented human form is provided. The body-engineering and corporeal-mutation practices that Stelarc employs foreground the tendency of contemporary art tο move beyond the confines of the staged theatrical performance tο more challenging but self-inflicting mediums of representation.

Foreign Bodies: The Grotesque Body in the Fiction of Jeanette Winterson
Creators: name: Palmer, Paulina
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2003

description: Referring tο the ideas of Mary Russo, Julio Kristeva and other postmodern critics and theorists, my essay discusses the representation of the grotesque body and its significance in terms of gender and sexual orientation in Jeanette Winterson's The Passion, Sexing the Cherry and Written on the Body. Winterson, as Ι illustrate, utilises the motif of the grotesque body subversively, employing it to celebrate the material dimension of existence, to interrogate and critique the mysogynistic image of the monstrous feminine and to resignify the boundaries of the object. The motif is relevant not only to her portrayal of character but also to her treatment of narrative and imagery. It finds expression in her use of imagery and narrative, as well as informing the intertextual aspect of her writing.

description: The lithium niobate integrated photonic platform has recently shown great promise in nonlinear optics on a chip scale. Here, we report second-harmonic generation in a high-Q lithium niobate microring resonator through modal phase matching, with a conversion efficiency of 1,500% W$^{-1}$. Our device also allows us to observe difference-frequency generation in the telecom band. Our work demonstrates the great potential of the lithium niobate integrated platform for nonlinear wavelength conversion with high efficiencies.
Magnetic field effects on the proton EDM in a continuous all-electric storage ring

description: Electric dipole moment of the proton can be searched in an electric storage ring by measuring the spin precession rate of the proton beam on the vertical plane. In the ideal case, the spin precession comes from the coupling between the electric field and the electric dipole moment. In a realistic scenario, the magnetic field becomes a major systematic error source as it couples with the magnetic dipole moment in a similar way. The beam can see the magnetic field in various configurations which include direction, time dependence, etc. For instance, geometric phase effect is observed when the beam sees the field at different directions and phases periodically. We have simulated the effect of the magnetic field in the major independent scenarios and found consistent results with the analytical estimations regarding the static magnetic field cases. We have set a limit for the magnetic field in each scenario and proposed solutions to avoid systematic errors from magnetic fields.
Consider the Blonde Head Severed: Subverting Beauty in Victorian Literature
Creators: name: Morgentaler, Goldie
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2003

description: While glorification of the womanly ideal of the Angel in the House was wide-spread in Victorian culture, there co-existed with this glorification a resistance to the ideal among nineteenth-century British authors of both sexes. Furthermore, the close association of blonde hair with the kind of holiness usually attributed tο angels elicited among some Victorian writers a corresponding urge tο desecrate the beauty of the blonde heroine in particular. This essay argues that the urge tο desecrate the beautiful blonde can be seen as a kind of sub-theme in Victorian literature, a subtheme that turns the female blonde into a victim of violence, violence that is often portrayed as her own fault. However, while the destructive violence that the blonde inspires may be interpreted as misogynistic, it also has larger connotations, in that it is not only anti-female but anti-aesthetic as well. Μy essay argues that the urge tο destroy human beauty is not far removed from the urge tο destroy beautiful things, a hypothesis that Ι demonstrate through an analysis of specific works by George Eliot, Charles Dickens, Christina Rossetti and Bram Stoker.

Perseus's Shield: The Politics of the Body in Humanitarian Campaigns
Creators: name: Paschalidis, Gregory
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2003

description: The starved, wounded or otherwise abused body predominates in the iconography of contemporary humanitarian campaigns (by organizations such as Amnesty International, Médecins sans Frontiéres and Action Aid), being an essential part of their distinctive rhetoric and mode of address. This particular way of visualizing the body has been widely accused of sensationalism, emotional manipulation and depoliticization. On the basis of the historical and cultural contextualization of the role that the image of the abused body has in the articulation both of humanitarian and of nationalist discourse, this paper analyzes the visual rhetoric of humanitarian campaigns with the aim, first, of revealing the contradictions and potentialities of this particular form of body politics; and, secondly, of investigating its significance to the constitution of post/trans-national moral and political communities.

Dynamics of Lattice Kinks

Subjects: subject: Pattern Formation and Solitons (nlin.PS)

description: In this paper we consider two models of soliton dynamics (the sine Gordon and the ϕ^4 equations) on a 1-dimensional lattice. We are interested in particular in the behavior of their kink-like solutions inside the Peierls- Nabarro barrier and its variation as a function of the discreteness parameter. We find explicitly the asymptotic states of the system for any value of the discreteness parameter and the rates of decay of the initial data to these asymptotic states. We show that genuinely periodic solutions are possible and we identify the regimes of the discreteness parameter for which they are expected to persist. We also prove that quasiperiodic solutions cannot exist. Our results are verified by numerical simulations.

description: When implementing Markov Chain Monte Carlo (MCMC) algorithms, perturbation caused by numerical errors is sometimes inevitable. This paper studies how perturbation of MCMC affects the convergence speed and Monte Carlo estimation accuracy. Our results show that when the original Markov chain converges to stationarity fast enough and the perturbed transition kernel is a good approximation to the original transition kernel, the corresponding perturbed sampler has similar convergence speed and high approximation accuracy as well. We discuss two different analysis frameworks: ergodicity and spectral gap, both are widely used in the literature. Our results can be easily extended to obtain non-asymptotic error bounds for MCMC estimators.
 We also demonstrate how to apply our convergence and approximation results to the analysis of specific sampling algorithms, including Random walk Metropolis and Metropolis adjusted Langevin algorithm with perturbed target densities, and parallel tempering Monte Carlo with perturbed densities. Finally we present some simple numerical examples to verify our theoretical claims.

description: Variational quantum circuits have been widely employed in quantum simulation and quantum machine learning in recent years. However, quantum circuits with random structures have poor trainability due to the exponentially vanishing gradient with respect to the circuit depth and the qubit number. This result leads to a general standpoint that deep quantum circuits would not be feasible for practical tasks. In this work, we propose an initialization strategy with theoretical guarantees for the vanishing gradient problem in general deep quantum circuits. Specifically, we prove that under proper Gaussian initialized parameters, the norm of the gradient decays at most polynomially when the qubit number and the circuit depth increase. Our theoretical results hold for both the local and the global observable cases, where the latter was believed to have vanishing gradients even for very shallow circuits. Experimental results verify our theoretical findings in the quantum simulation and quantum chemistry.

The Body In Situ, the Body in Crisis: From the Happenings of Allan Kaprow to the Vienna Actionists
Creators: name: Armand, Claudine
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2003

description: This paper explores the link between representation and power in the visual arts along the lines of Foucault and Artaud, and the aim is to highlight the way art is determined and affected by place, context, and time. Ιt starts with the USA in the 1950s and the happenings of Allan Kaprow and other artists of the period, who decided that art should no longer be self-contained but part of life and continuous with it. These artists showed a particular interest in the material environment and a new awareness of the body. What emerges from this movement is the interaction between the body and space and between the artist and the spectator. The latter is an active part of the performance. He improνises, is influenced, and affected by his surroundings. With the Vienna Actionists, the body becomes the signifier, an object of experimentation and manipulation. Such practices lead to a questioning of the viewer's perception of his own body and reflect the preoccupations of other European artists in the post-war era. In this sense, art becomes a subversive act in a society which is felt to be repressive and inhibiting. The article ends with a few contemporary artists, like Jan Fabre, who continue tο investigate the body/power dialectics and whose multimedia approach puts eνen greater emphasis on the link between body and language in our highly technologically-oriented society.

Evolving Einstein's Field Equations with Matter: The ``Hydro without Hydro'' Test

description: We include matter sources in Einstein's field equations and show that our recently proposed 3+1 evolution scheme can stably evolve strong-field solutions. We insert in our code known matter solutions, namely the Oppenheimer-Volkoff solution for a static star and the Oppenheimer-Snyder solution for homogeneous dust sphere collapse to a black hole, and evolve the gravitational field equations. We find that we can evolve stably static, strong-field stars for arbitrarily long times and can follow dust sphere collapse accurately well past black hole formation. These tests are useful diagnostics for fully self-consistent, stable hydrodynamical simulations in 3+1 general relativity. Moreover, they suggest a successive approximation scheme for determining gravitational waveforms from strong-field sources dominated by longitudinal fields, like binary neutron stars: approximate quasi-equilibrium models can serve as sources for the transverse field equations, which can be evolved without having to re-solve the hydrodynamical equations (``hydro without hydro'').

Corporeality and the Metropolis: Dissolving the Body in Paul Auster's The New York Trilogy
Creators: name: Nigianni, Betty
Publisher: name: Gramma: Journal of Theory and Criticism
Year: 2003

description: This article deals with the theme of the shattering of the body in the contemporary urban environment as it appears in Ρaul Auster's The New York Trilogy. In the three novels of The Trilogy, the writer deals with the complex interaction between the metropolitan cityscape and the human body: moving through a labyrinthine New York whose dimensions exceed by far the human scale, Auster's heroes experience Conditions of depersonalization and assumed absorption by space, which finally lead them to the extreme state of the dissolution of their bodies. This transgression of the physical body, that "melting into the walls of the city " (139) , is however celebrated by Auster as a form of transgression of logical boundaries, which enables thought tο reveal its poetic nature: the heroes may disappear in the end, they leaνe behind them however a written story - product and witness of their existence in the postmodern city that escapes all anthropomorphic qualities in order to reveal a more archaic and inspiring imagery.
