description: We study noise in the problem of tunneling between fractional quantum Hall edge states within a four probe geometry. We explore the implications of the strong-weak coupling duality symmetry existent in this problem for relating the various density-density auto-correlations and cross-correlations between the four terminals. We identify correlations that transform as either ``odd'' or ``anti-symmetric'', or ``even'' or ``symmetric'' quantities under duality. We show that the low frequency noise is colored, and that the deviations from white noise are exactly related to the differential conductance. We show explicitly that the relationship between the slope of the low frequency noise spectrum and the differential conductance follows from an identity that holds to {\it all} orders in perturbation theory, supporting the results implied by the duality symmetry. This generalizes the results of quantum supression of the finite frequency noise spectrum to Luttinger liquids and fractional statistics quasiparticles.

description: Automated social media bots have existed almost as long as the social media environments they inhabit. Their emergence has triggered numerous research efforts to develop increasingly sophisticated means to detect these accounts. These efforts have resulted in a cat and mouse cycle in which detection algorithms evolve trying to keep up with ever evolving bots. As part of this continued evolution, our research proposes a multi-model 'tool-box' approach in order to conduct detection at various tiers of data granularity. To support this toolbox approach this research also uses random string detection applied to user names to filter twitter streams for bot accounts and use this as labeled training data for follow on research.

description: Counterfactual communication, i.e., communication without particle travelling in the transmission channel, is a bizarre quantum effect. Starting from interaction-free measurements many protocols achieving various tasks from counterfactual cryptogrphy to counterfactual transfer of quantum states were proposed and implemented in experiments. However, the meaning of conterfactuality in various protocols remained a controversial topic. A simple error-free counterfactual protocol is proposed. This protocol and its modification are used as a test bed for analysis of meaning of counterfactuality to clarify the counterfactuality status of various counterfactual proposals.

description: Shortly after fixating on webpages, users form initial impressions. These initial impressions influence how much users will use and return to websites. Researchers have understudied how objective design features (e.g. visual complexity) influence subjective perceptions of website content and the favorability of initial user impressions. In the present study, the influence of two dimensions of visual complexity – feature complexity and design complexity – were tested within the boundaries of the persuasive model of web design. More specifically, the study examined how visual complexity influences perceptions of visual informativeness, cues for engagement, favourable initial impressions, and behavioural intentions in a sample of young adults (N = 277). Results suggest relationships for both dimensions of visual complexity on all outcome variables using ANOVA and OLS regression procedures and that perceptions of visual informativeness and cues for engagement mediate the relationship between visual complexity and favourable initial impressions and behavioural intentions. The study offers support for the utility of the persuasive model of web design for linking objective design features with subjective design perceptions to better understand favourable initial user impressions.
Efficient simulation of the swept-waveform polarization dynamics in fiber spools and Fourier domain mode-locked (FDML) lasers

description: We present a theoretical model and its efficient numerical implementation for the simulation of wavelength-swept waveform propagation in fiber systems such as Fourier domain mode-locked (FDML) lasers, fully accounting for the polarization dynamics in fiber spools and further polarization dependent optical components in the setup. This approach enables us to perform long-time simulations of the FDML laser dynamics over more than 100000 cavity roundtrips, as required for some FDML configurations to ensure convergence to the steady state operating regime. The model is validated against experimental results for single propagation through a fiber spool and for stationary FDML operation. The polarization dynamics due to the fiber spool, inducing polarization-mode dispersion, bending birefringence as well as cross-phase modulation, and other optical components such as the Faraday-rotating mirror used for polarization compensation is thoroughly investigated.

Neural Based Statement Classification for Biased Language
Creators: name: Hube, Christoph

Publisher: name: arXiv
Year: 2018
Subjects: subject: Computation and Language (cs.CL)
subject: FOS: Computer and information sciences

description: Biased language commonly occurs around topics which are of controversial nature, thus, stirring disagreement between the different involved parties of a discussion. This is due to the fact that for language and its use, specifically, the understanding and use of phrases, the stances are cohesive within the particular groups. However, such cohesiveness does not hold across groups. In collaborative environments or environments where impartial language is desired (e.g. Wikipedia, news media), statements and the language therein should represent equally the involved parties and be neutrally phrased. Biased language is introduced through the presence of inflammatory words or phrases, or statements that may be incorrect or one-sided, thus violating such consensus. In this work, we focus on the specific case of phrasing bias, which may be introduced through specific inflammatory words or phrases in a statement. For this purpose, we propose an approach that relies on a recurrent neural networks in order to capture the inter-dependencies between words in a phrase that introduced bias. We perform a thorough experimental evaluation, where we show the advantages of a neural based approach over competitors that rely on word lexicons and other hand-crafted features in detecting biased language. We are able to distinguish biased statements with a precision of P=0.92, thus significantly outperforming baseline models with an improvement of over 30%. Finally, we release the largest corpus of statements annotated for biased language.

Nonlinear interactions between solitons and dispersive shocks in focusing media

description: Nonlinear interactions in focusing media between traveling solitons and the dispersive shocks produced by an initial discontinuity are studied using the one-dimensional nonlinear Schrodinger equation. It is shown that, when solitons travel from a region with nonzero background towards a region with zero background, they always pass through the shock structure without generating dispersive radiation. However, their properties (such as amplitude, velocity and shape) change in the process. A similar effect arises when solitons travel from a region with zero background towards a region with nonzero background, except that, depending on its initial velocity, in this case the soliton may remain trapped inside the shock-like structure indefinitely. In all cases, the new soliton properties can be determined analytically. The results are validated by comparison with numerical simulations.

description: The spectrum of the integrable spin-S Heisenberg chains is completely characterized in terms of spin-1/2 spinons. In the continuum limit they form a quasi-particle basis to the higher level SU(2) Wess-Zumino-Witten (WZW) models. Enumerating the spinon states in finite systems we obtain effective single particle distribution functions for these objects which generalize Haldane's generalized exclusion principle to quasi-particles with non-Abelian exchange statistics.

description: Student weighted funding is the most widely used means to ensure schools have enough money to provide for the differing needs of students. However, research suggests the benefits of student weighted funding go well beyond adequate resources for specific-needs students, offering significant improvements in (1) general education programming; (2) more targeted and efficient usage of tax dollars, and (3) long-term benefits including higher property values, improved business investments, and lower social costs. While there are considerable differences in how effective student weighted formulae are, they provide the capacity for a more efficient and calibrated use of tax dollars with community-wide benefits.
Graph theoretical approaches for the characterization of damage in hierarchical materials

description: We discuss the relevance of methods of graph theory for the study of damage in simple model materials described by the random fuse model. While such methods are not commonly used when dealing with regular random lattices, which mimic disordered but statistically homogeneous materials, they become relevant in materials with microstructures that exhibit complex multi-scale patterns. We specifically address the case of hierarchical materials, whose failure, due to an uncommon fracture mode, is not well described in terms of either damage percolation or crack nucleation-and-growth. We show that in these systems, incipient failure is accompanied by an increase in eigenvector localization and a drop in topological dimension. We propose these two novel indicators as possible candidates to monitor a system in the approach to failure. As such, they provide alternatives to monitoring changes in the precursory avalanche activity, which is often invoked as a candidate for failure prediction in materials which exhibit critical-like behavior at failure, but may not work in the context of hierarchical materials which exhibit scale-free avalanche statistics even very far from the critical load.

description: Indoor wayfinding is an important and complex daily activity. In this study, we aimed to explore the indoor wayfinding performance of pedestrians of different genders under time pressure. We conducted a wayfinding experiment in a real-world subway station in Beijing using eye-tracking and verbal protocol methods and analyzed wayfinding efficiency, strategies and eye movement data from 38 participants. The results indicated that both male and female participants experienced more difficulty reading maps under time pressure. We also found that males consistently had higher efficiency when they searched for information and could extract information from signage more efficiently than females when they were not under time pressure. Males were more adventurous and preferred to take risks under time pressure, while females consistently maintained a conservative strategy. These findings contribute to the understanding of gender differences in indoor wayfinding and cognition.

description: Purpose: Blast-related brain and ocular injuries can lead to acute and chronic visual dysfunction. The chronic visual consequences of blast exposure and its progression remain unclear. The goal of this study is to analyze ocular functional response to four levels of blast exposure and identify a threshold of blast exposure leading to acute and chronic visual dysfunction. Methods: Anesthetized adult male Long-Evans rats received a single-blast exposure at a peak overpressure of 78, 117, 164 or 213 kPa, delivered by a compressed air-driven shock tube. Clinical eye examination, intraocular pressure (IOP), flash electroretinography (fERG) and spectral-domain optical coherence tomography (SD-OCT) images were assessed prior to, and at multiple time points post exposure. Results: No abnormal fERG were observed for the two lowest-level blast groups (78 kPa or 117 kPa). For the 164 kPa group, the a- and b-wave amplitudes of the fERG were decreased at 3 days postexposure (p = 0.009 for a-wave, p = 0.010 for b-wave), but recovered to baseline levels by 7 days post-exposure. The IOP was unchanged for the 117 kPa and 164 kPa groups. The 78 kPa group demonstrated a small transient increase during week one (p = 0.046). For the highest blast group (213 kPa), the IOP was significantly elevated immediately post-exposure (p = 0.0001), but recovered by 24 hr. A bimodal depression in the fERG a- and b-wave amplitudes was observed for this group: the amplitudes were depressed at day 3 post-exposure (p = 0.007 for a-wave, p = 0.012 for b-wave), and recovered by day 7 post-exposure. However, the fERG amplitudes were once again depressed at week 8 post-exposure, suggesting a chronic retinal dysfunction. All retinae appeared normal in SD-OCT images. Conclusions: Our study demonstrates that a single-blast exposure may result in acute and chronic fERG deficit, and traumatic IOP elevation. Noninvasive functional tests may hold promise for identifying individuals with a risk for developing chronic visual deficits, and indicating a time window for early clinical diagnosis, rehabilitation, and treatment.

description: We construct the higher twist structure functions that describe inclusive b hadron decays in regions of phase space where the hadronic decay products carry high energy but have low invariant mass. We show that, for B meson decays, there are four new non-vanishing matrix elements of non-local operators. We show that to subleading twist these decays are parametrized in terms of four functions. We compute the tree-level matching for a general heavy-to-light current and apply it to B -> X_s gamma. Using a simple model for these functions we estimate the subleading twist contributions to this decay.

description: We investigate the zero-temperature collective excitations of a Bose-condensed atomic gas in anisotropic parabolic traps. The condensate density is determined by solving the Gross-Pitaevskii (GP) equation using a spherical harmonic expansion. The GP eigenfunctions are then used to solve the Bogoliubov equations to obtain the collective excitation frequencies and mode densities. The frequencies of the various modes, classified by their parity and the axial angular momentum quantum number, m, are mapped out as a function of the axial anisotropy. Specific emphasis is placed upon the evolution of these modes from the modes in the limit of an isotropic trap.

description: The bipolar collimated outflows of the Hb4 Planetary Nebula (PN) exhibit an evident decrease in their expansion velocity with respect to the distance from the central star. So far, similar velocity law has also been found in Herbig-Haro objects. The interpretation of this peculiar velocity law and the classification of the outflows is the main focal point of this paper. High dispersion long-slit echelle spectra along with high resolution images from Hubble Space Telescope (HST) are applied in the astronomical code SHAPE in order to reproduce a three-dimensional morpho-kinematical model for the core and the bipolar outflows. Its central part shows a number of low-ionization filamentary structures (knots and jets) indicative of common-envelope PNe evolution and it is reconstructed assuming a toroidal structure. The high-resolution HST [N II] image of Hb4 unveils the fragmented structure of outflows. The northern and southern outflows are composed by four and three knots, respectively, and each knot moves outwards with its own expansion velocity. They are reconstructed as string of knots rather than jets.This string of knots is formed by ejection events repeated every 200- 250 years. Hb4 displays several indirect evidence for a binary central system with a [WR] companion evolved through the common envelopes channel.The observed deceleration of the knots is likely associated with shock collisions between the knots and the interstellar medium or nebular material.

We prove that a $k\times k$-block-matrix has non zero determinant if and only if all $k\times k$-block matrices have non zero determinant. We use this result to extend the notion of propagation phenomena to $k$-hyponormal weighted shifts. Finally we give a study on invariance of $k$-hyponormal weighted shifts under one rank perturbation.

description: We investigate the zero mode dimensional reduction of the Kaluza-Klein unifications in the presence of a single brane in the infinite extra dimension. We treat the brane as fixed, not a dynamical object, and do not require the orbifold symmetry. It seems that, contrary to the standard Kaluza-Klein models, the 4D effective action is no longer invariant under the U(1) gauge transformations due to the explicit breaking of isometries in the extra dimension by the brane. Surprisingly, however, the linearized perturbation analysis around the RS vacuum shows that the Kaluza-Klein gauge field does possess the U(1) gauge symmetry at the linear level. In addition, the graviscalar also behaves differently from the 4D point of view. Some physical implications of our results are also discussed.

There is a large difference in the phase diagrams between arrays of macroscopic and mesoscopic objects for $n_0 < 5$ and $U

description: We have studied superconductor/normal metal/superconductor (SNS) junctions consisting of short Au or Cu wires between Nb or Al banks. The Nb based junctions display inherent electron heating effects induced by the high thermal resistance of the NS boundaries. The Al based junctions show in addition subharmonic gap structures in the differential conductance dI/dV and a pronounced peak in the excess noise at very low voltages V. We suggest that the noise peak is caused by fluctuations of the supercurrent at the onset of Josephson coupling between the superconducting banks. At intermediate temperatures where the supercurrent is suppressed a noise contribution ~1/V remains, which may be interpreted as shot noise originating from large multiple charges.

description: A new physical origin for electroweak symmetry breaking is proposed, involving compact spatial dimensions of scale 1/R \approx 1 TeV. The higher dimensional theory is supersymmetric, and hence requires the top-quark Yukawa coupling to be localized on some ``Yukawa brane'' in the bulk. The short distance divergence in the Higgs-boson mass is regulated because supersymmetry is unbroken in the vicinity of this Yukawa brane. A finite, negative Higgs mass-squared is generated radiatively by the top-quark supermultiplet propagating a distance of order R from the Yukawa brane to probe supersymmetry breaking. The physics of electroweak symmetry breaking is therefore closely related to this top propagation across the bulk, and is dominated by the mass scale 1/R, with exponential insensitivity to higher energy scales. The masses of the superpartners and the Kaluza-Klein resonances are also set by the mass scale 1/R, which is naturally larger than the W boson mass by a loop factor. Explicit models are constructed which are highly constrained and predictive. The finite radiative correction to the Higgs mass is computed, and the Higgs sector briefly explored. The superpartner and Kaluza-Klein resonance spectra are calculated, and the problem of flavor violation from squark and slepton exchange is solved. Important collider signatures include highly ionizing charged tracks from stable top squarks, and events with two Higgs bosons and missing transverse energy.

description: We report the first demonstration of solid-state optical refrigeration of a Ho-doped material. A 1 mol% Ho-doped Yttrium Lithium Fluoride (YLF) crystal is cooled by mid-IR laser radiation, and its external quantum efficiency and parasitic background absorption are evaluated. Using detailed temperature-dependent spectroscopic analysis the minimum achievable temperature of a 1% Ho:YLF sample is estimated. Owing to its narrower ground- and excited-state manifolds, larger absorption cross-section, and coincidence of optimum cooling wavelength of 2070 nm with commercially available high-power and highly efficient Tm-fiber lasers, Ho^3+-doped crystals are superior to Tm^3+-doped systems for mid-IR optical refrigeration. With further improvement in material purity and increased doping concentration, they offer great potential towards enhancing the cooling efficiency nearly two-fold over the best current Yb:YLF systems, achieving lower temperatures as well as for realization of eye-safe mid-IR high-power radiation balanced lasers.

description: Electron transport in a quantum wire with leads is investigated with actual Coulomb interaction taken into account. The latter includes both the direct interaction of electrons with each other and their interaction via the image charges induced in the leads. Exact analytical solution of the problem is found with the use of the bosonization technique for one-dimensional electrons and three-dimensional Poisson equation for the electric field. The Coulomb interaction is shown to change significantly the electron density distribution along the wire as compared with the Luttinger liquid model with short-range interactions. In DC and low frequency regimes, the Coulomb interaction causes the charge density to increase strongly in the vicinity of the contacts with the leads. The quantum wire impedance shows an oscillating behavior versus the frequency caused by the resonances of the charge waves. The Coulomb interaction produces a frequency dependent renormalization of the charge wave velocity.

description: Heterogeneous systems are ubiquitous and are growing to include even more diverse paradigms, such as quantum computing. This paper strives to design an asynchronous task-based runtime solution that can encapsulate both classical and quantum computing environments in the heterogeneous execution paradigm by exploring a few integration possibilities between the task-based runtime IRIS, the quantum programming framework XACC, and the Quantum Intermediate Representation Execution Engine (QIR-EE). The need for asynchronous task-based execution is motivated by examples that require the coexistence of classical and quantum computing hardware. To show a proof-of-concept for motivating future study, we describe the principles of integrating quantum runtimes with a task-based runtime and demonstrate its capability of parallelizing quantum circuit execution by decomposing a four-qubit circuit into a collection of smaller circuits, which lowers the quantum simulation load during execution. We hope that this will further highlight challenges that we would need to overcome to make such a solution effectively scalable while simultaneously capturing classical-quantum andquantum-quantum interactions.

description: We investigate how much a first-quantized charged bosonic test string gets excited after crossing a shock wave generated by a charged particle with mass $\tilde{M}$ and charge $\tilde{Q}$. On the basis of Kaluza-Klein theory, we pay attention to a closed string model where charge is given by a momentum along a compactified extra-dimension. The shock wave is given by a charged Aichelburg-Sexl (CAS) spacetime where $\tilde{Q}=0$ corresponds to the ordinary Aichelburg-Sexl one. We first show that the CAS spacetime is a solution to the equations of motion for the metric, the gauge field, and the axion field in the low-energy limit. Secondly, we compute the mass expectation value of the charged test string after passing through the shock wave in the CAS spacetime. In the case of small $\tilde{Q}$, gravitational and Coulomb forces are canceled out each other and hence the excitation of the string remains very small. This is independent of the particle mass $\tilde{M}$ or the strength of the shock wave. In the case of large $\tilde{Q}$, however, every charged string gets highly excited by quantum fluctuation in the extra-dimension caused by both the gauge and the axion fields. This is quite different from classical "molecule", which consists of two electrically charged particles connected by a classical spring.

Influence of magnetic impurities on the heat capacity of nuclear spins

description: It is found that in a wide range of temperatures and magnetic fields even a small concentration of magnetic impurities in a sample leads to a $T^{-1}$ temperature dependence of the nuclear heat capacity. This effect is related to a nuclear-spin polarization by the magnetic impurities. The parameter that controls the theory turns out not to be the impurity concentration $C_{imp}$ but instead the quantity $c_{imp} μ_e / μ_n$, where $μ_e$ and $μ_n$ are the magnetic moments of an electron and a nucleus, respectively. The ratio of $μ_e$ and $μ_n$ is of order of $10^3$.

description: We report here the electrical transport and magnetic properties of the newly synthesized quaternary Heusler compound CoFeTiSn and CoFeVGa. We observe a striking change in the electronic transport properties of CoFeTiSn as the system undergoes the paramagnetic to ferromagnetic transition. While the sample shows an activated semiconducting behaviour in the paramagnetic phase, it turns abruptly to a metallic phase with the onset of ferromagnetic transition. We have compared the system with other Hesuler compounds showing similar anomaly in transport, and it appears that CoFeTiSn has much similarities with the Fe$_2$VAl compound having pseudogap in the paramagnetic phase. In sharp contrast, CoFeVGa shows a predominantly semiconducting behaviour down to 90 K, below which it shows a window of metallic region. Both the compositions show negative Seebeck coefficient varying linearly with temperature. The value of the Seebeck coefficient of CoFeTiSn is comparable to that of many Heusler alloys identified as potential thermoelectric materials.
Classical diffusion of N interacting particles in one dimension: General results and asymptotic laws

description: I consider the coupled one-dimensional diffusion of a cluster of N classical particles with contact repulsion. General expressions are given for the probability distributions, allowing to obtain the transport coefficients. In the limit of large N, and within a gaussian approximation, the diffusion constant is found to behave as N^{-1} for the central particle and as (\ln N)^{-1} for the edge ones. Absolute correlations between the edge particles increase as (\ln N)^{2}. The asymptotic one-body distribution is obtained and discussed in relation of the statistics of extreme events.

description: Purpose: Blast-related brain and ocular injuries can lead to acute and chronic visual dysfunction. The chronic visual consequences of blast exposure and its progression remain unclear. The goal of this study is to analyze ocular functional response to four levels of blast exposure and identify a threshold of blast exposure leading to acute and chronic visual dysfunction. Methods: Anesthetized adult male Long-Evans rats received a single blast exposure at peak overpressure of 78, 117, 164 or 213 kPa, delivered by a compressed air-driven shock tube. Clinical eye examination, intraocular pressure (IOP), flash electroretinography (fERG) and spectral-domain optical coherence tomography (SD-OCT) images were assessed prior to, and at multiple time points post exposure. Results: No abnormal fERG were observed for the two lowest-level blast groups (78 kPa or 117 kPa). For the 164 kPa group, the a- and b-wave amplitudes of the fERG were decreased at 3 days post- exposure (p = 0.009 for a-wave, p = 0.010 for b-wave), but recovered to baseline levels by 7 days post-exposure. The IOP was unchanged for the 117 kPa and 164 kPa groups. The 78 kPa group demonstrated a small transient increase during week one (p = 0.046). For the highest blast group (213 kPa), the IOP was significantly elevated immediately post-exposure (p = 0.0001), but recovered by 24 hours. A bimodal depression in the fERG a- and b-wave amplitudes was observed for this group: the amplitudes were depressed at day 3 post-exposure (p = 0.007 for a-wave, p = 0.012 for b-wave), and recovered by day 7 post-exposure. However, the fERG amplitudes were once again depressed at week 8 post-exposure, suggesting a chronic retinal dysfunction. All retinae appeared normal in SD-OCT images. Conclusions: Our study demonstrates that a single blast exposure may result in acute and chronic fERG deficit, and traumatic IOP elevation. Noninvasive functional tests may hold promise for identifying individuals with a risk for developing chronic visual deficits, and indicating a time window for early clinical diagnosis, rehabilitation and treatment.
