Higher Spin Currents in the N=2 Stringy Coset Minimal Model

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

description: In the coset model based on (A_{N-1}^{(1)} \oplus A_{N-1}^{(1)}, A_{N-1}^{(1)}) at level (N, N; 2N), it is known that the N=2 superconformal algebra can be realized by the two kinds of adjoint fermions. Each Kac-Moody current of spin-1 is given by the product of fermions with structure constant (f symbols) as usual. One can construct the spin-1 current by combining the above two fermions with the structure constant and the spin-1 current by multiplying these two fermions with completely symmetric SU(N) invariant tensor of rank 3 (d symbols). The lowest higher spin-2 current with nonzero U(1) charge (corresponding to the zeromode eigenvalue of spin-1 current of N=2 superconformal algebra) can be obtained from these four spin-1 currents in quadratic form. Similarly, the other type of lowest higher spin-2 current, whose U(1) charge is opposite to the above one, can be obtained also. Four higher spin-5/2 currents can be constructed from the operator product expansions (OPEs) between the spin-3/2 currents of N=2 superconformal algebra and the above two higher spin-2 currents. The two higher spin-3 currents can be determined by the OPEs between the above spin-3/2 currents and the higher spin-5/2 currents. Finally, the ten N=2 OPEs between the four N=2 higher spin multiplets (2, 5/2, 5/2, 3), (2, 5/2, 5/2, 3), (7/2, 4, 4, 9/2) and (7/2, 4, 4, 9/2) are obtained explicitly for generic N.

description: We report low-temperature electronic transport measurements performed in two multi-terminal Corbino samples formed in GaAs/Al-GaAs two-dimensional electron gases (2DEG) with both ultra-high electron mobility ($\gtrsim 20\times 10^6$ $cm^2/Vs)$ and with distinct electron density of $1.7$ and $3.6\times 10^{11}~cm^{-2}$. In both Corbino samples, a non-monotonic behavior is observed in the temperature dependence of the resistance below 1~$K$. Surprisingly, a sharp {\it decrease} in resistance is observed with {\it increasing} temperature in the sample with lower electron density, whereas an opposite behavior is observed in the sample with higher density. To investigate further, transport measurements were performed in large van der Pauw samples having identical heterostructures, and as expected they exhibit resistivity that is monotonic with temperature. Finally, we discuss the results in terms of various lengthscales leading to ballistic and hydrodynamic electronic transport, as well as a possible Gurzhi effect.
A Neural Span-Based Continual Named Entity Recognition Model

description: Named Entity Recognition (NER) models capable of Continual Learning (CL) are realistically valuable in areas where entity types continuously increase (e.g., personal assistants). Meanwhile the learning paradigm of NER advances to new patterns such as the span-based methods. However, its potential to CL has not been fully explored. In this paper, we propose SpanKL, a simple yet effective Span-based model with Knowledge distillation (KD) to preserve memories and multi-Label prediction to prevent conflicts in CL-NER. Unlike prior sequence labeling approaches, the inherently independent modeling in span and entity level with the designed coherent optimization on SpanKL promotes its learning at each incremental step and mitigates the forgetting. Experiments on synthetic CL datasets derived from OntoNotes and Few-NERD show that SpanKL significantly outperforms previous SoTA in many aspects, and obtains the smallest gap from CL to the upper bound revealing its high practiced value.

description: Nishikawa (2007) proposed to reformulate the classical Poisson equation as a steady state problem for a linear hyperbolic system. This results in optimal error estimates for both the solution of the elliptic equation and its gradient. However, it prevents the application of well-known solvers for elliptic problems. We show connections to a discontinuous Galerkin (DG) method analyzed by Cockburn, Guzmán, and Wang (2009) that is very difficult to implement in general. Next, we demonstrate how this method can be implemented efficiently using summation by parts (SBP) operators, in particular in the context of SBP DG methods such as the DG spectral element method (DGSEM). The resulting scheme combines nice properties of both the hyperbolic and the elliptic point of view, in particular a high order of convergence of the gradients, which is one order higher than what one would usually expect from DG methods for elliptic problems.

description: In der vorliegenden Arbeit werden zwei neue Verfahren zur Ansteuerung von Drehstromstellern vorgestellt, die die auftretenden Verlustenergien im Drehstromsteller und Asynchronmotor reduzieren. Es wird sowohl der Start- als auch der Bremsbetrieb betrachtet. Zunächst wird dazu ein Ansatz präsentiert mit dem Zündentscheidungen auf Basis einer Prädiktion getroffen werden. Dieser Ansatz wird so ergänzt, dass ein rampenförmiger Hochlauf möglich ist, wie Anwender ihn von heutigen Industrieprodukten kennen. Außerdem werden erste Validierungsmessungen präsentiert. Im Folgenden wird das „Softstarter Torque and Flux Control”-Verfahren (STFC-Verfahren) vorgestellt, das das Verhalten des prädiktiven Verfahrens nachbildet. Die Nachbildung geschieht mit deutlich verringertem Rechenaufwand und erfordert kaum noch Kenntnis der Parameter des angeschlossenen Motors. Anschließend wird das STFC-Verfahren so umgebaut, dass zusätzlich auf die Verwendung eines Drehgebers verzichtet werden kann. Abschließend wird die Eignung der klassischen Phasenanschnittsteuerung, des prädiktiven Verfahrens, des STFC-Verfahrens und des geberlosen STFC-Verfahrens für verschiedene Applikationen ausführlich diskutiert. Außerdem werden Stärken und Schwächen der Verfahren diskutiert.

description: In the present paper we have discussed in detail electromagnetically induced transparency and signal storing in the case of one signal pulses propagating in a classical electric medium resembling this of four-level atoms in the tripod configuration. Our theoretical results confirm recently observed dependence of transparency windows position on coupling parameters. In the process of storing the pulse energy is confined inside the metamaterial as electric charge oscillations and after required time it is possible to switch the control fields on again and to release the trapped signal. By manipulating the driving fields one can thus control the parameters of the released signal and even to divide it on demand into arbitrary parts.

description: We report on the use of radio-frequency optical atomic magnetometers for magnetic induction tomography measurements. We demonstrate the imaging of dummy targets of varying conductivities placed in the proximity of the sensor, in an unshielded environment at room-temperature and without background subtraction. The images produced by the system accurately reproduce the characteristics of the actual objects. Furthermore, we perform finite element simulations in order to assess the potential for measuring low-conductivity biological tissues with our system. Our results demonstrate the feasibility of an instrument based on optical atomic magnetometers for magnetic induction tomography imaging of biological samples, in particular for mapping anomalous conductivity in the heart.

description: A Latin square of order $n$ is an $n \times n$ matrix of $n$ symbols, such that each symbol occurs exactly once in each row and column. For an odd prime power $q$ let $\mathbb{F}_q$ denote the finite field of order $q$. A quadratic Latin square is a Latin square $\mathcal{L}[a, b]$ defined by, $$(\mathcal{L}[a, b])_{i, j} = \begin{cases} i + a(j-i) & \text{if } j-i \text{ is a quadratic residue in } \mathbb{F}_q, \\ i + b(j-i) & \text{otherwise}, \end{cases}$$ for some $\{a, b\} \subseteq \mathbb{F}_q$ such that $ab$ and $(a-1)(b-1)$ are quadratic residues in $\mathbb{F}_q$. Quadratic Latin squares have previously been used to construct perfect $1$-factorisations, mutually orthogonal Latin squares and atomic Latin squares. We first characterise quadratic Latin squares which are devoid of $2 \times 2$ Latin subsquares. Let $G$ be a graph and $\mathcal{F}$ a $1$-factorisation of $G$. If the union of every pair of $1$-factors in $\mathcal{F}$ induces a Hamiltonian cycle in $G$ then $\mathcal{F}$ is called perfect, and if there is no pair of $1$-factors in $\mathcal{F}$ which induce a Hamiltonian cycle in $G$ then $\mathcal{F}$ is called anti-perfect. We use quadratic Latin squares to construct new examples of anti-perfect $1$-factorisations of complete graphs and complete bipartite graphs. We also demonstrate that for each odd prime $p$, there are only finitely many orders $q$, which are powers of $p$, such that quadratic Latin squares of order $q$ could be used to construct perfect $1$-factorisations of complete graphs or complete bipartite graphs.

description: Most complex systems are intrinsically dynamic in nature. The evolution of a dynamic complex system is typically represented as a sequence of snapshots, where each snapshot describes the configuration of the system at a particular instant of time. Then, one may directly follow how the snapshots evolve in time, or aggregate the snapshots within some time intervals to form representative "slices" of the evolution of the system configuration. This is often done with constant intervals, whose duration is based on arguments on the nature of the system and of its dynamics. A more refined approach would be to consider the rate of activity in the system to perform a separation of timescales. However, an even better alternative would be to define dynamic intervals that match the evolution of the system's configuration. To this end, we propose a method that aims at detecting evolutionary changes in the configuration of a complex system, and generates intervals accordingly. We show that evolutionary timescales can be identified by looking for peaks in the similarity between the sets of events on consecutive time intervals of data. Tests on simple toy models reveal that the technique is able to detect evolutionary timescales of time-varying data both when the evolution is smooth as well as when it changes sharply. This is further corroborated by analyses of several real datasets. Our method is scalable to extremely large datasets and is computationally efficient. This allows a quick, parameter-free detection of multiple timescales in the evolution of a complex system.

We give a self-contained introduction to these topics and give the details concerning the saddle point approach for the usual single trace and multitrace matrix models. We then review the attempts to explain the phase structure of the fuzzy field theory using a corresponding random matrix ensemble, showing the strength and weaknesses of this approach. We conclude with a list of challenges one needs to overcome and the most interesting open problems one can try to solve.

description: First principles of electromagnetism impose that the tangential electric field must be continuous at the interface between two media. The definition of the electric field depends on the frame of reference leading to an ambiguity in the mathematical expression of the continuity condition when the two sides of the interface do not share the same rest frame. We briefly review the arguments supporting each choice of interface condition and illustrate how the most theoretically consistant choice leads to a paradox in induction experiments. We then present a model of sliding contact between two solids and between a fluid and a solid, and show how this paradox can be lifted by taking into account the shear induced by the differential motion in a thin intermediate viscous layer at the interface, thereby also lifting the ambiguity in the electric interface condition. We present some guidelines regarding the appropriate interface condition to employ in magnetohydrodynamics applications, in particular for numerical simulations where sliding contact is used as an approximation to the viscous interface between a conducting solid and a fluid of very low viscosity such as in planetary interior simulations.

description: Middleboxes have become a vital part of modern networks by providing service functions such as content filtering, load balancing and optimization of network traffic. An ordered sequence of middleboxes composing a logical service is called service chain. Service Function Chaining (SFC) enables us to define these service chains. Recent optimization models of SFCs assume that the functionality of a middlebox is provided by a single software appliance, commonly known as Virtual Network Function (VNF). This assumption limits SFCs to the throughput of an individual VNF and resources of a physical machine hosting the VNF instance. Moreover, typical service providers offer VNFs with heterogeneous throughput and resource configurations. Thus, deploying a service chain with custom throughput can become a tedious process of stitching heterogeneous VNF instances. In this paper, we describe how we can overcome these limitations without worrying about underlying VNF configurations and resource constraints. This prospect is achieved by distributed deploying multiple VNF instances providing the functionality of a middlebox and modeling the optimal deployment of a service chain as a mixed integer programming problem. The proposed model optimizes host and bandwidth resources allocation, and determines the optimal placement of VNF instances, while balancing workload and routing traffic among these VNF instances. We show that this problem is NP-Hard and propose a heuristic solution called Kariz. Kariz utilizes a tuning parameter to control the trade-off between speed and accuracy of the solution. Finally, our solution is evaluated using simulations in data-center networks.

description: Simultaneous broadband spectral and temporal studies of blazars are an important tool for investigating active galactic nuclei (AGN) jet physics. We study the spectral evolution between quiescent and flaring periods of 22 radio-loud AGN through multi-epoch, quasi-simultaneous broadband spectra. For many of these sources these are the first broadband studies. We use a Bayesian block analysis of \Fermi/LAT light curves in order to determine time ranges of constant flux for constructing quasi-simultaneous SEDs. The shapes of the resulting 81 SEDs are described by two logarithmic parabolas and a blackbody spectrum where needed. For low states the peak frequencies and luminosities agree well with the blazar sequence, higher luminosity implying lower peak frequencies. This is not true for sources in a high state. The $γ$-ray photon index in Fermi/LAT correlates with the synchrotron peak frequency in low and intermediate states. No correlation is present in high states. The black hole mass cannot be determined from the SEDs. Surprisingly, the thermal excess often found in FSRQs at optical/UV wavelengths can be described by blackbody emission and not an accretion disk spectrum. The "harder-when-brighter" trend, typically seen in X-ray spectra of flaring blazars, is visible in the blazar sequence. Our results for low and intermediate states, as well as the Compton dominance, are in agreement with previous results. Black hole mass estimates using the parameters from Bonchi (2013) are in agreement with some of the more direct measurements. For two sources, estimates disagree by more than four orders of magnitude, possibly due to boosting effects. The shapes of the thermal excess seen predominantly in flat spectrum radio quasars are inconsistent with a direct accretion disk origin.

description: In this paper, I show that Julius Caesar’s character, appeal, and motivations (as seen in Plutarch’s Life) were much more complex than most scholars believe. It is true that Plutarch’s Caesar felt an irresistible ambition for power and that he often drew on his strategic brilliance to serve his own political interests. Yet power for power’s sake was far from enough for him. Plutarch demonstrates, in fact, that Caesar’s drive to become an absolute ruler stemmed not only from his longings for power and glory, but also from his desire to distribute benefits and justice to his subjects and to deserve the honor and gratitude they gave him in return. Caesar’s overweening confidence in his ability to establish new, just orders was hugely attractive to the Roman people, who felt unfairly oppressed by the existing laws. Though Plutarch indicates that Caesar’s self-assessment was unsupported by serious examination of questions regarding justice, he also suggests that Caesar’s (and his people’s) deep concern for justice played a key role in his rise to the throne.

description: Families of $N$ interacting curves are considered, with long range, mean field type, interaction. A family of curves defines a 1-current, concentrated on the curves, analog of the empirical measure of interacting point particles. This current is proved to converge, as $N$ goes to infinity, to a mean field current, solution of a nonlinear, vector valued, partial differential equation. In the limit, each curve interacts with the mean field current and two different curves have an independence property if they are independent at time zero. This set-up is inspired from vortex filaments in turbulent fluids, although for technical reasons we have to restrict to smooth interaction, instead of the singular Biot-Savart kernel. All these results are based on a careful analysis of a nonlinear flow equation for 1-currents, its relation with the vector valued PDE and the continuous dependence on the initial conditions.

description: The formalism of the continuum random-phase approximation theory which treats, without ap- proximations, the continuum part of the single-particle spectrum, is extended to describe charge- exchange excitations. Our approach is self-consistent, meaning that we use a unique, finite-range, interaction in the Hartree-Fock calculations which generate the single-particle basis and in the con- tinuum random-phase approximation which describes the excitation. We study excitations induced by the Fermi, Gamow-Teller and spin-dipole operators in doubly magic nuclei by using four Gogny- like finite-range interactions, two of them containing tensor forces. We focus our attention on the importance of the correct treatment of the continuum configuration space and on the effects of the tensor terms of the force.1

description: The explicit compact expression for the susceptibility tensor of a single photon wave packet on the photon mass-shell is derived. It is assumed that the probe photon is hard, the test photon is soft, and their total energy is below the electron-positron pair creation threshold. It turns out that a single photon wave packet can be regarded as a birefringent gyrotropic dispersive medium in the process of light-by-light scattering. The explicit expression for the inclusive probability to record the probe photon in the process of light-by-light scattering is obtained in the first nontrivial order of perturbation theory where the interference effect of the free passed and scattered parts of the photon wave function dominates. This effect is of order $α^2$ in contrast to the standard contribution to the light-by-light scattering cross-section which is of order $α^4$. The possible nontrivial shapes of the wave functions of probe and test photons are taken into account. The evolution of the Stokes parameters of a probe photon is described. The change of the Stokes parameters is rather large for hard probe photons and sufficiently intense beams of soft test photons.

description: OBJECTIVES: To compare the mental health and life satisfaction of those employed in the gig work and contingent work with those in full-time or part-time work and the unemployed in the UK during the COVID-19 pandemic. To explore the possible mechanisms of latent and manifest benefits of employment, such as financial precarity and loneliness. DESIGN: Cross-sectional survey. PARTICIPANTS: A representative sample of 17 722 employed and unemployed British adults, including 429 gig workers. People with disability, retirees and full-time students are not included in the sample. MAIN OUTCOME MEASURES: Mental health (General Health Questionnaire-12 score) and life satisfaction (a direct question from UK Household Longitudinal Study (UKHLS)) as outcomes. Self-reported loneliness (four widely used questions from UKHLS) and financial precarity (a direct question from UKHLS) as mediators. RESULTS: Gig workers reported mental health and life satisfaction worse than those employed full time and part time, but better than the unemployed. Mediation analyses showed that gig workers' worse mental health and life satisfaction than other workers were explained by their higher levels of loneliness and financial precarity, while gig workers' better mental health and life satisfaction than the unemployed were explained by their less financial precarity. CONCLUSIONS: Informal and freelance economy provided manifest benefits of employment to gig workers compared with unemployment but lacked latent benefits of employment. Public policies should provide social support to freelance and contingent workers to reduce their loneliness and improve their psychological well-being, especially during the COVID-19 pandemic.

Essays on supervised principal component analysis for forecasting
Creators: name: Li, Wanjun
Publisher: name: No Publisher Supplied
Year: 2022

description: This dissertation enhances the conventional Principal Component Analysis for the purpose of Forecasting. Principal Component Analysis is a classic method to summarize information with latent factors. However, the latent factors explaining the input features may not have a strong predictive relationship with the target variable. This dissertation presents a novel Supervised Principal Component Analysis (SPCA) to fill this gap. The dissertation consists of three chapters.Chapter 1, “Opportunities and Challenges of Principal Component Analysis in Forecasting” reviews the development of PCA. OLS is problematic as N/T goes to infinity, or when the multicollinearity becomes serious. Studies have found evidence of PCA dominating OLS in forecasting economic variables, for its advantages of dimension reduction with orthogonal factors. However, the nature of PCA as an unsupervised method is undesirable in forecasting. Attempts to incorporate the features and target variable in PCA are limited. The prevailing direction is to add an extra step in extracting factors with PCA. This motivates my exploration of embedding supervision directly in factor extraction.Chapter 2, “Supervised Principal Component Analysis and Asymptotic Theories” establishes a new method. The open-form solution of SPCA has been provided. The expansions and the distributions of SPCA factors and forecasting errors are investigated as well. As N goes to infinity, SPCA approaches to PCA. However when sample size is limited SPCA could improve the forecasts.Chapter 3, “Simulation Evidence of Supervised Principal Component Analysis” further explores the relationships between SPCA and PCA. It identifies the conditions when SPCA outperforms PCA by varying the assumptions, including missepcified models. The conditions include: 1) The number of factors is large; 2) The variance of each factor’ loadings are different; 3) Factors important in explaining x are not so important in forecasting y; 4) N is small; 5) u in yₜ₊ₕ = Fₜβ + u is close to 0.Chapter 4, “Forecasting Bond Risk Premia, Macro Variables and Stock Returns” corroborate the value of SPCA in economic and financial applications. It reduced the mean squared forecast errors (MSFE) of PCA as much as 30% for bond risk premia. Similar strong improvement is found for Housing Starts and M2 money supply. SPCA can be easily implemented on Sieve-LS Covariance matrix to extract factors. And the factors combined with non-linear forecasting models like semi-parametric Index model and Neural Network further reduced the MSFE. On the other hand, factor models have been substantially explored in stock returns. Long-short zero investment portfolios were formed according to the excess return forecasts. Equal-weighted portfolios formed by SPCA generated 10% higher Sharpe Ratio (1.14) than those formed by PCA, with similar maximum drawdown and turnover.
Dynamical Features of Open Star Cluster: DOLIDZE 14

description: The radial density profile (RDP) of cluster DOLIDZE 14 provides the radius of 9.8 arcmin, it is based on consideration of first plateau region of RDP. This value is less than the radius which comes through consideration of the second plateau region. The stars, which are inside of the cluster radius, are used to estimate the distance-modulus and E(I-R) by fitting theoretical isochrone on the colour-magnitude diagram (CMD). The best fitted stellar isochrone of solar matellacity provides these values as 11.15 mag and 0.25 mag, respectively. These results are used to estimate the mass-function slope of the cluster, which comes to be different that of Salpeter-Value. The enhancement of brighter stars does not found within the cluster region which indicates its old age. The Mass-Segregation phenomena of cluster is found between massive and lighter stars but not found in fainter stars, having magnitude greater than 15 mag in I-band. The relaxation-time is very little in the comparison of its age. The mean proper motion of cluster's radial zones is found to be high in the comparison of field region (12.77-15.18 arcmin). This is indicative of weak-gravitational bond among the stars of the cluster.

Design, testing and analysis of COVID-19 breathalyzer
Creators: name: Harris, Joshua
Publisher: name: No Publisher Supplied
Year: 2022

description: This thesis is the portion of the author’s contribution to a group project that was funded by the National Institutes of Health to create a new form of a respiratory test. With a primary focus on detecting the SARS-CoV-2 virus and its variations, the breathalyzer test is then planned to be adaptable to detect and distinguish between different types of respiratory diseases such as MERS, SARS and influenza. The appeal to a breathalyzer test is tantalizing because breathalyzers are easy to use compared to other forms of COVID-19 testing. Breathing, a simple form of COVID-19 transmission, is all that is expected for the test. The mechanism behind this transmission is the production of aerosol particles, which carry viruses when individuals are sick with respiratory diseases.The key component behind the design of a breathalyzer is a way of capturing the aerosol particles. Several methods of capturing particles are explored and addressed in the thesis, along with the choice that was ultimately selected. Once sufficient aerosol particles are captured, they come into contact with the sensor technology developed by Rutgers University, is able to detect an electrical signal if there is a sufficient viral load.The theory behind the flow created in a breathalyzer exists, but never for such a specific application as a respiratory test. Not only is there nozzle flow, but also there are significant disturbance downstream that allow for air to continue to flow through, while simultaneously collecting the aerosol particles. Computational Fluid Dynamics were used to help predict and visualize the airflow and aid with prototype design. Moreover, in an attempt to best capture the most particles, certain parameters were optimized to see if that improved performance. A main indicator of performance, at of the time this thesis was completed, was measured by what is called as “capture efficiency”, which is the percentage of mass that exited the breathalyzer. Results of these was analyzed to see if there was trend in efficiency based on certain parametric features.Empirical tests were done at Rutgers University with a realistic setup to emulate the flow of breath into the breathalyzer. CFD is used to visualize and predict the flow physics not seen through empirical tests or the naked eye.As this thesis is completed, research is still ongoing in an attempt to perfect the current design and further optimize the system. Once completed, along with the optimization of the sensor technology, human trials will begin.
Reproducibly Analyzing Wildfire, Drought, and Flood Risk with NASA Earthdata Cloud

description: This document is a proposal from 2i2c and MetaDocencia (both are fiscally sponsored projects of Code for Science & Society) to the NASA SMD call for proposals F.14 Transform to Open Science Training (NNH22ZDA001N-TOPST). This was one of 16 successfully funded proposals under the program. In this proposed TOPS ScienceCore module, learners will learn to identify, extract, analyze, visualize, and report on data available through NASA Earthdata Cloud for three different scenarios: wildfire, drought, and flood risk. The module will build upon TOPS OpenScience 101 and reinforce principles of reproducibility and open science-based workflows. Computationally, the scenarios will estimate changes in the hydrological water mass balance for defined regions primarily using remote sensing data. We will demonstrate best practices in “data-proximate computing” by considering examples that involve computing climatologies and other statistics from long-time series using numerical methods that scale well with the data being available on the cloud. This module will leverage scientific Python libraries such as Xarray and Dask to perform the computations. The focus of this module will be on data processing and visualization and doing so in a reproducible and transparent way.
Coherent-state-induced transparency

description: We examine electromagnetically induced transparency (EIT) in an ensemble of cold $Λ-$type atoms induced by a quantum control field in multi-mode coherent states and compare it with the transparency created by the classical light of the same intensity. We show that the perfect coincidence is achieved only in the case of a single-mode coherent state, whereas the transparency sharply decreases, when the number of the modes exceeds the mean number of control photons in the medium. The origin of the effect is the modification of photon statistics in the control field with increasing the number of the modes that weakens its interaction with atoms resulting in a strong probe absorption. For the same reason, the probe pulse transforms from EIT-based slow-light into superluminal propagation caused by the absorption.
