description: In this work, we systematically investigate how well current models of coherence can capture aspects of text implicated in discourse organisation. We devise two datasets of various linguistic alterations that undermine coherence and test model sensitivity to changes in syntax and semantics. We furthermore probe discourse embedding space and examine the knowledge that is encoded in representations of coherence. We hope this study shall provide further insight into how to frame the task and improve models of coherence assessment further. Finally, we make our datasets publicly available as a resource for researchers to use to test discourse coherence models.

description: We derive and study a quantum group g(p,q) that is Kazhdan--Lusztig-dual to the W-algebra W(p,q) of the logarithmic (p,q) conformal field theory model. The algebra W(p,q) is generated by two currents $W^+(z)$ and $W^-(z)$ of dimension (2p-1)(2q-1), and the energy--momentum tensor T(z). The two currents generate a vertex-operator ideal $R$ with the property that the quotient W(p,q)/R is the vertex-operator algebra of the (p,q) Virasoro minimal model. The number (2 p q) of irreducible g(p,q)-representations is the same as the number of irreducible W(p,q)-representations on which $R$ acts nontrivially. We find the center of g(p,q) and show that the modular group representation on it is equivalent to the modular group representation on the W(p,q) characters and ``pseudocharacters.'' The factorization of the g(p,q) ribbon element leads to a factorization of the modular group representation on the center. We also find the g(p,q) Grothendieck ring, which is presumably the ``logarithmic'' fusion of the (p,q) model.

Coping with interpersonal stressors : issues of love and status
Creators: name: Preece, Melady
Publisher: name: University of British Columbia
Year: 2009

description: Diary data collected over seven days from 81 stepfamily couples were used to examine the relations between stress appraisals and coping responses. Stress appraisals were conceptualized as issues of love and status (Wiggins & Trapnell, 1996). Secondary appraisals of control were also considered. Coping was measured with a Brief Ways of Coping (BWOC) scale developed for use in diary studies. Additional subscales measured empathie responding, support provision, compromise, interpersonal withdrawal, and self-care. Coping strategies were organized on an interpersonal circumplex according to their intercorrelations and their relations to appraisals. Hierarchical Linear Modeling (HLM; Bryk & Raudenbush, 1992) was used to analyze diary data. Appraisals explained significant portions of daily variance in the use of coping strategies as well as significant variance between individuals. The usefulness of conceptualizing coping strategies with reference to their relations to appraisals of stress within a circumplex structure was demonstrated. Relationship-focused coping was shown to be an important category in the study of coping with interpersonal stressors. It was suggested that coping strategies may best be conceived of as Roschian concepts with "fuzzy" boundaries as opposed to clear-cut categories.
The role of orthogonal polynomials in the six-vertex model and its combinatorial applications

description: The Hankel determinant representations for the partition function and boundary correlation functions of the six-vertex model with domain wall boundary conditions are investigated by the methods of orthogonal polynomial theory. For specific values of the parameters of the model, corresponding to 1-, 2- and 3-enumerations of Alternating Sign Matrices (ASMs), these polynomials specialize to classical ones (Continuous Hahn, Meixner-Pollaczek, and Continuous Dual Hahn, respectively). As a consequence, a unified and simplified treatment of ASMs enumerations turns out to be possible, leading also to some new results such as the refined 3-enumerations of ASMs. Furthermore, the use of orthogonal polynomials allows us to express, for generic values of the parameters of the model, the partition function of the (partially) inhomogeneous model in terms of the one-point boundary correlation functions of the homogeneous one.

description: We investigate the impact of the substrate on the structural properties and the morphology of alkanethiol self-assembled monolayers (SAMs) on gold, using first principles calculations and atomistic molecular dynamics simulations. We consider hexadecanethiols on Au(211), Au(221) and Au(311) surfaces which contain few-atom wide terraces separated by monoatomic steps similar to the complex Au surfaces used in experiments. The structure of the SAMs is probed via several structural properties including tilt angles, mean C atom heights from the surface, precession angles, gauche defects, gyration tensors and relative shape anisotropy. Comparing these properties to those of the well-studied SAMs on Au(111), we observe similarities but also striking differences. A clear order to disorder transition is observed by changing the substrate: well-ordered SAMs on (111) and (211) surfaces become mixed ordered-disordered structures on (311) and fully disordered on (221). The presence of steps on the Au surfaces also results in preferential tilt orientations with long-range order. Our results show that in addition to the expected grafting density dependence, the transition from order to disorder crucially depends on substrate morphology. The onset of ordering behavior is related to the atomic structure of the surface. The key parameter that affects long-range order is the energy for changing the dihedral angle between Au-S-$\mathrm{C^{(1)}-C^{(2)}}$ of the adsorbed alkanethiol.
The Impact of Post-editing and Machine Translation on Creativity and Reading Experience

description: This article presents the results of a study involving the translation of a fictional story from English into Catalan in three modalities: machine-translated (MT), post-edited (MTPE) and translated without aid (HT). Each translation was analysed to evaluate its creativity. Subsequently, a cohort of 88 Catalan participants read the story in a randomly assigned modality and completed a survey. The results show that HT presented a higher creativity score if compared to MTPE and MT. HT also ranked higher in narrative engagement, and translation reception, while MTPE ranked marginally higher in enjoyment. HT and MTPE show no statistically significant differences in any category, whereas MT does in all variables tested. We conclude that creativity is highest when professional translators intervene in the process, especially when working without any aid. We hypothesize that creativity in translation could be the factor that enhances reading engagement and the reception of translated literary texts.

description: We report on the realization of an all-fiber laser source that delivers single-frequency pulses at 1645 nm, on a linearly polarized single-mode beam, based on stimulated Raman scattering in passive fibers. The pulse energy reaches 14 $μ$J, for a repetition rate of 20 kHz, and the spectral linewidth is 9.5 MHz, almost Fourier-transform limited for the 100 ns square pulses. To the best of our knowledge, this energy is the highest reported at 1645 nm in an all-fiber laser source. Our method consists in reducing the stimulated Brillouin scattering (SBS) gain for the pump and signal pulses, respectively by sweeping the optical frequency of the pump beam, and by applying a strain gradient on the amplification fiber. This compact laser source is now used in a transportable lidar system to measure simultaneously wind velocity and methane (CH4) concentration.

description: The inner crust of neutron stars formed of nuclear clusters immersed in a neutron sea has been widely studied in the framework of the Wigner-Seitz approximation since the seminal work of Negele and Vautherin. In this article, the validity of this approximation is discussed in the framework of the band theory of solids. For a typical cell of $^{200}$Zr, present in the external layers of the inner crust, it is shown that the ground state properties of the neutron gas are rather well reproduced by the Wigner-Seitz approximation, while its dynamical properties depend on the energy scale of the process of interest or on the temperature. It is concluded that the Wigner-Seitz approximation is well suited for describing the inner crust of young neutron stars and the collapsing core of massive stars during supernovae explosions. However the band theory is required for low temperature fluid dynamics.

A rhapsody of errors

description: Over the course of a number of different MinION sequencing runs of mouse mitochondrial DNA, we had the opportunity to investigate how the MinION sequence output could be applied to genotyping. Despite the high error rate (up to 15% for early sequencing runs), most of this sequencing error is random in nature and can be filtered out when multiple reads are aggregated for genotyping. While the technology is not ideal for genotyping long homopolymer stretches, it is more than adequate for genotyping the more common point mutations.

One of the methods we have developed for visualising the results of sequencing follows a form similar to electrophoretograms produced from Sanger sequencing, with additional data points for sequence insertions and deletions. This graphical representation allows for a quick visual confirmation of genotyping results, and demonstrates how effective genotyping can be, even in the presence of substantial amounts of random error.

Most of the error involved in sequencing lies at the software side of the device. This presents a very encouraging view of the future of MinION sequencing, even for results produced on older flow cells with older chemistries. We investigated potential causes of sequencing error, looking at regions where raw sensor signal was inappropriately partitioned or dropped, and have also looked at the error profile of the base calling model for different 5-mer sequences. These investigations have demonstrated that an alternative method of base calling with more model inputs and fewer model outputs is feasible, and could potentially improve accuracy of base calling in the future.

description: In this work, we report a radio galaxy with precessing jets, double-peaked emission lines and the presence of two compact radio components with a projected separation of ~6 parsec in Very Long Baseline Interferometry (VLBI) observations. The emission line peak separations could be suggesting the presence of a supermassive black hole binary (BBH) with a separation of 6.3 parsec, matching the VLBI results. The kinematic jet precession model applied to the jets of J1328+2751 indicates that if it is a BBH, the accretion disk of the primary black hole is not coplanar with the binary system orbit, making its jet precess under the effect of the torque produced by the secondary black hole. However, we find that the Bardeen-Petterson effect can also provide precession timescales compatible with the jet precession period inferred in this source. This source has previously been identified as a restarted double-double radio galaxy (DDRG). Our findings therefore have important ramifications for the nature of DDRGs in general.

description: We demonstrate confinement of $^{85}$Rb atoms in a dark, toroidal optical trap. We use a spatial light modulator to convert a single blue-detuned Gaussian laser beam to a superposition of Laguerre-Gaussian modes that forms a ring-shaped intensity null bounded harmonically in all directions. We measure a 1/e spin-relaxation lifetime of ~1.5 seconds for a trap detuning of 4.0 nm. For smaller detunings, a time-dependent relaxation rate is observed. We use these relaxation rate measurements and imaging diagnostics to optimize trap alignment in a programmable manner with the modulator. The results are compared with numerical simulations.

description: In earlier work, planar graphs of massless phi^3 theory were summed with the help of the light cone world sheet picture and the mean field approximation. In the present article, the same methods are applied to the problem of summing planar bosonic open strings. We find that in the ground state of the system, string boundaries form a condensate on the world sheet, and a new string emerges from this summation. Its slope is always greater than the initial slope, and it remains non-zero even when the initial slope is set equal to zero. If we assume that the initial string tends to some field theory in the zero slope limit, this result provides evidence for string formation in field theory.

description: Background and aim. Prevention of phantom limb pain (PLP) still remains an unsolved problem. Our study presents a novel multimodal approach to prevent PLP using special drug prevention (SDP) scheme composed of 5 components which as we assumed should be able to suppress specific pathogenetic PLP mechanisms on different levels of peripheral and central nervous system: anticonvulsant (Gabapentin), corticosteroid (Dexamethasone), protease inhibitor (Aprotinin), NMDA-receptor antagonist (Ketamine) and tricyclic antidepressant (Amitriptyline).

Material and methods. The study included 28 oncological patients aged 48+19 who underwent planned high amputation of lower/upper limb under general anesthesia (Group 1: GA, n=14) or GA+Epidural anesthesia (Group 2: GA+EA, n=14). Standard intra- and postoperative monitoring, VRS 0-4 at rest and during movement, questionnaire “Pain Detect” were performed. Five components were used in addition to traditional means of anesthesia and analgesia in different combinations 2-4 days before, during amputation and for 6 months after.

Results. During 7-10 days following amputation patients experienced only mild sensory symptoms which were ceased on SDP and mild pain in stump (VRS): 1.38+0.3 (Group 1), 1.4+0.3 (Group 2). During 6-months follow-up none of patients of both groups complained of any phantom symptoms. No complications and SAE were registered. By the time of abstract preparation the presented multimodal approach allowed to completely prevent PLP in 53 patients and became a part of routine practice in our institution.

Conclusion. The novel multimodal 5 component scheme demonstrates high long-term efficacy in phantom limb pain prevention. Implementation of this technology will markedly improve life quality and social activities including the perspective for further prostheses using.

description: A coordinate-space representation for a charged scalar particle propagator in a constant magnetic field was obtained as a series over the Landau levels. Using the recently developed modified Fock-Schwinger method, an intermediate expression was constructed and symmetrized, thus, allowing for factorization of the series terms into two factors. The first one, a sum of Bessel functions, depends on time and $z$-coordinate, where the $z$-axis is chosen to be a direction of the magnetic field, and has a structure similar to the propagator of a free field. The second one, a product of a Laguerre polynomial and a damping exponential, depends on $x,y$-coordinates, which form a plane perpendicular to the direction of the magnetic field, and ensures the localized propagation in the $x,y$-plane.

We evaluate the static potential by analyzing the classical action of a string attaching the rectangular Wilson loop on a probe D3 brane sitting at an intermediate position in the bulk AdS space. We observe that the inclusion of chemical potential tends to enhance the production rate, reverse to the effect of confining scale. Also, we calculate the critical electric field by Dirac-Born-Infeld (DBI) action.

description: Semidefinite programming is an important optimization task, often used in time-sensitive applications. Though they are solvable in polynomial time, in practice they can be too slow to be used in online, i.e. real-time applications. Here we propose to solve feasibility semidefinite programs using artificial neural networks. Given the optimization constraints as an input, a neural network outputs values for the optimization parameters such that the constraints are satisfied, both for the primal and the dual formulations of the task. We train the network without having to exactly solve the semidefinite program even once, thus avoiding the possibly time-consuming task of having to generate many training samples with conventional solvers. The neural network method is only inconclusive if both the primal and dual models fail to provide feasible solutions. Otherwise we always obtain a certificate, which guarantees false positives to be excluded. We examine the performance of the method on a hierarchy of quantum information tasks, the Navascués-Pironio-Acín hierarchy applied to the Bell scenario. We demonstrate that the trained neural network gives decent accuracy, while showing orders of magnitude increase in speed compared to a traditional solver.

description: In certain applications, for instance biomechanics, turbulence, finance, or Internet traffic, it seems suitable to model the data by a generalization of a fractional Brownian motion for which the Hurst parameter $H$ is depending on the frequency as a piece-wise constant function. These processes are called multiscale fractional Brownian motions. In this contribution, we provide a statistical study of the multiscale fractional Brownian motions. We develop a method based on wavelet analysis. By using this method, we find initially the frequency changes, then we estimate the different parameters and afterwards we test the goodness-of-fit. Lastly, we give the numerical algorithm. Biomechanical data are then studied with these new tools.

What is the impact of ICU syndrome experienced by a critically ill patient from the perspective of the family member?
Creators: name: Shorthouse, Lucille Jeanne Christine
Publisher: name: University of British Columbia
Year: 2009

description: ICU syndrome is a mental syndrome of acute onset that occurs in some patients in a critical care unit. This syndrome continues to occur frequently and serves to increase both morbidity and mortality in affected patients. Despite the continued occurrence a" limited amount of information is known about the effects on the patients, and nothing is known about the effects on family members. A literature review indicates no specific qualitative studies had been conducted in this area. Some related research studies indicated that a critical illness affects not only the patient but family members as well. A critical illness compounded by ICU syndrome, can have the potential for long-term effects for both the patient and the family. This study was designed to gain an understanding of ICU syndrome from the perspective of the family members. A qualitative descriptive methodology was used to guide this study. This approach was guided by the assumption that people do make order and sense of their environment although this world may appear disoriented and nonsensical to others. Ten family members of patients who experienced ICU syndrome agreed to participate in this study. Interviews were conducted on two separate occasions. Analysis of the data revealed that participants identified 12 major categories of responses in relation to ICU syndrome. The participants identified some responses similar to the literature reviewed, but also brought forth several findings that moved beyond the current literature. These findings indicated that ICU syndrome caused them to take on greater roles in the family unit. Respondents exhibited great strength, cared a great deal for the patient, and demonstrated caring, helpful and supportive roles. These roles were maintained throughout the hospitalization. The occurrence of the syndrome meant that the respondents would need to reassess their plans for the future. Information was needed by the respondents specifically related to the syndrome and this need was not always met adequately by the health care team. The patients exhibited a great deal of trust in the respondents to help them while they were ill and/or suffering from the syndrome. The respondents felt it was important for them to try to make some meaning of the behaviours noted during the syndrome and to pass on this information to the staff who did not know the patient as they did. The findings are discussed in relation to the framework and literature reviewed. Areas that move beyond the information currently known about family members responses are discussed and recommendations for nursing practice included.

description: Donor spin in silicon have achieved record values of coherence times and single-qubit gate fidelities. The next stage of development involves demonstrating high-fidelity two-qubit logic gates, where the most natural coupling is the exchange interaction. To aid the efficient design of scalable donor-based quantum processors, we model the two-electron wave function using a full configuration interaction method within a multi-valley effective mass theory. We exploit the high computational efficiency of our code to investigate the exchange interaction, valley population, and electron densities for two phosphorus donors in a wide range of lattice positions, orientations, and as a function of applied electric fields. The outcomes are visualized with interactive images where donor positions can be swept while watching the valley and orbital components evolve accordingly. Our results provide a physically intuitive and quantitatively accurate understanding of the placement and tuning criteria necessary to achieve high-fidelity two-qubit gates with donors in silicon.

description: We examine observational characteristics of multi-phase turbulent flows in the diffuse interstellar medium (ISM) using a synthetic radiation field of atomic and molecular lines. We consider the multi-phase ISM which is formed by thermal instability under the irradiation of UV photons with moderate visual extinction $A_V\sim 1$. Radiation field maps of C$^{+}$, C$^0$, and CO line emissions were generated by calculating the non-local thermodynamic equilibrium (nonLTE) level populations from the results of high resolution hydrodynamic simulations of diffuse ISM models. By analyzing synthetic radiation field of carbon lines of [\ion{C}{2}] 158 $μ$m, [\ion{C}{1}] $^3P_2-^3P_1$ (809 GHz), $^3P_1-^3P_0$ (492 GHz), and CO rotational transitions, we found a high ratio between the lines of high- and low-excitation energies in the diffuse multi-phase interstellar medium. This shows that simultaneous observations of the lines of warm- and cold-gas tracers will be useful in examining the thermal structure, and hence the origin of diffuse interstellar clouds.

description: We show by explicit closed form calculations that a Hurst exponent H that is not 1/2 does not necessarily imply long time correlations like those found in fractional Brownian motion. We construct a large set of scaling solutions of Fokker-Planck partial differential equations where H is not 1/2. Thus Markov processes, which by construction have no long time correlations, can have H not equal to 1/2. If a Markov process scales with Hurst exponent H then it simply means that the process has nonstationary increments. For the scaling solutions, we show how to reduce the calculation of the probability density to a single integration once the diffusion coefficient D(x,t) is specified. As an example, we generate a class of student-t-like densities from the class of quadratic diffusion coefficients. Notably, the Tsallis density is one member of that large class. The Tsallis density is usually thought to result from a nonlinear diffusion equation, but instead we explicitly show that it follows from a Markov process generated by a linear Fokker-Planck equation, and therefore from a corresponding Langevin equation. Having a Tsallis density with H not equal to 1/2 therefore does not imply dynamics with correlated signals, e.g., like those of fractional Brownian motion. A short review of the requirements for fractional Brownian motion is given for clarity, and we explain why the usual simple argument that H unequal to 1/2 implies correlations fails for Markov processes with scaling solutions. Finally, we discuss the question of scaling of the full Green function g(x,t;x',t') of the Fokker-Planck pde.

They Do Change After All: 25 Years of GONG Data Reveal Variation of p-Mode Energy Supply Rates

description: It has been shown over and over again that the parameters of solar p modes vary through the solar activity cycle: frequencies, amplitudes, lifetimes, energies. However, so far, the rates at which energy is supplied to the p modes have not been detected to be sensitive to the level of magnetic activity. We set out to re-inspect their temporal behaviour over the course of the last two Schwabe cycles. For this, we use Global Oscillation Network Group (GONG) p-mode parameter tables. We analyse the energy supply rates for modes of harmonic degrees $l=0\text{-}150$ and average over the azimuthal orders and, subsequently, over modes in different parameter ranges. This averaging greatly helps in reducing the noise in the data.We find that energy supply rates are anti-correlated with the level of solar activity, for which we use the $F_{10.7}$ index as a proxy. Modes of different mode frequency and harmonic degrees show varying strengths of anti-correlation with the $F_{10.7}$ index, reaching as low as $r=-0.82$ for low frequency modes with $l=101\text{-}150$. In this first dedicated study of solar p-mode energy supply rates in GONG data, we find that they do indeed vary through the solar cycle. Earlier investigations with data from other instruments were hindered by being limited to low harmonic degrees or by the data sets being too short. We provide tables of time-averaged energy supply rates for individual modes as well as for averages over disjunct frequency bins.

description: In this article we verify an orbifold version of a conjecture of Nimershiem from 1998. Namely, for every flat $n$-manifold $M$, we show that the set of similarity classes of flat metrics on $M$ which occur as a cusp cross-section of a hyperbolic $(n+1)$-orbifold is dense in the space of similarity classes of flat metrics on $M$. The set used for density is precisely the set of those classes which arise in arithmetic orbifolds.

description: The GRavitational lEnsing Accuracy Testing 2008 (GREAT08) Challenge focuses on a problem that is of crucial importance for future observations in cosmology. The shapes of distant galaxies can be used to determine the properties of dark energy and the nature of gravity, because light from those galaxies is bent by gravity from the intervening dark matter. The observed galaxy images appear distorted, although only slightly, and their shapes must be precisely disentangled from the effects of pixelisation, convolution and noise. The worldwide gravitational lensing community has made significant progress in techniques to measure these distortions via the Shear TEsting Program (STEP). Via STEP, we have run challenges within our own community, and come to recognise that this particular image analysis problem is ideally matched to experts in statistical inference, inverse problems and computational learning. Thus, in order to continue the progress seen in recent years, we are seeking an infusion of new ideas from these communities. This document details the GREAT08 Challenge for potential participants.

description: Electric-field control of magnetization dynamics is fundamentally and technologically important for future spintronic devices. Here, based on electric-field control of both magnetic anisotropy and spin--orbit torque, two distinct methods are presented for switching the magnetization in topological insulator (TI)/magnetic-TI hybrid systems. The magnetic anisotropy energy in magnetic TIs is formulated analytically as a function of the Fermi energy, and it is confirmed that the out-of-plane magnetization is always favored for the partially occupied surface band. Also proposed is a transistor-like device with the functionality of a nonvolatile magnetic memory that uses voltage-driven writing and the (quantum) anomalous Hall effect for readout. For the magnetization reversal, by using parameters of Cr-doped Bi_{1-x}Sb_{x})_{2}Te_{3}, the estimated source-drain current density and gate voltage are of the orders of $10^4$--$10^5$~A/cm$^2$ and 0.1~V, respectively, below 20~K and the writing requires no external magnetic field. Also discussed is the possibility of magnetization switching by the proposed method in TI/ferromagnetic-insulator bilayers with the magnetic proximity effect.

description: We discuss the impact of magnetic field on the mass - temperature relation for groups and clusters of galaxies based on the derivation of the general Magnetic Virial Theorem. The presence of a magnetic field B yields a decrease of the virial temperature T for a fixed mass M: such a decrease in T is stronger for low-mass systems than for high-mass systems. We outline several implications of the presence of B-field and of its mass scaling for the structure and evolution of groups and clusters.

description: Domain adaptation solves the learning problem in a target domain by leveraging the knowledge in a relevant source domain. While remarkable advances have been made, almost all existing domain adaptation methods heavily require large amounts of unlabeled target domain data for learning domain invariant representations to achieve good generalizability on the target domain. In fact, in many real-world applications, target domain data may not always be available. In this paper, we study the cases where at the training phase the target domain data is unavailable and only well-labeled source domain data is available, called robust domain adaptation. To tackle this problem, under the assumption that causal relationships between features and the class variable are robust across domains, we propose a novel Causal AutoEncoder (CAE), which integrates deep autoencoder and causal structure learning into a unified model to learn causal representations only using data from a single source domain. Specifically, a deep autoencoder model is adopted to learn low-dimensional representations, and a causal structure learning model is designed to separate the low-dimensional representations into two groups: causal representations and task-irrelevant representations. Using three real-world datasets the extensive experiments have validated the effectiveness of CAE compared to eleven state-of-the-art methods.
TeVeS gets caught on caustics

description: TeVeS uses a dynamical vector field with timelike unit norm constraint to specify a preferred local frame. When matter moves slowly in this frame - the so-called quasi-static regime - Modified Newtonian Dynamics (MoND) results. Theories with such vectors (such as Einstein-aether) are prone to the vector dynamics forming singularities which render their classical evolution problematic. Here we analyse the dynamics of the vector in TeVeS in various situations. We find that, quite generically, the vector field develops caustic singularities on time scales of order the gravitational in-fall time. Having shown singularity formation is generic with or without matter, Bekenstein's original formulation of TeVeS appears dynamically problematic. We argue that by modifying the vector field kinetic terms to the more general form used by Einstein-Aether this problem may be avoided.
