Criticality and Inflation of the Gauged B-L Model

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We consider the multiple point principle (MPP) and the inflation of the gauged B-L extension of the Standard Model (SM) with a classical conformality. We examine whether the scalar couplings and their beta functions can become simultaneously zero at $Λ_{\text{MPP}}:=10^{17}$ GeV by using the two-loop renormalization group equations (RGEs). We find that we can actually realize such a situation and that the parameters of the model are uniquely determined by the MPP. However, as discussed in \cite{Iso:2012jn}, if we want to realize the electroweak symmetry breaking by the radiative B-L symmetry breaking, the self coupling $λ_Ψ$ of a newly introduced SM singlet complex scalar $Ψ$ must have a non-zero value at $Λ_{\text{MPP}}$, which means the breaking of the MPP. We find that the ${\cal{O}}(100)$GeV electroweak symmetry breaking can be achieved even if this breaking is very small; $λ_Ψ(Λ_{\text{MPP}})\leq10^{-10}$. Within this situation, the mass of the B-L gauge boson is predicted to be \begin{equation} M_{B-L}=2\sqrt{2}\times\sqrt{\frac{λ(v_{h})}{0.10}}\times v_{h}\simeq 696\hspace{1mm}\text{GeV},\nonumber\end{equation} where $λ$ is the Higgs self coupling and $v_{h}$ is the Higgs expectation value. This is a remarkable prediction of the (slightly broken) MPP. Furthermore, such a small $λ_Ψ$ opens a new possibility: $Ψ$ plays a roll of the inflaton \cite{Okada:2011en}. Another purpose of this paper is to investigate the $λ_ΨΨ^{4}$ inflation scenario with the non-minimal gravitational coupling $ξΨ^{2} {\cal{R}}$ based on the two-loop RGEs.

description: We study the dynamics of a general quartic interaction Hamiltonian under the influence of dissipation and non-classical driving. We show that this scenario could be realised with a cascaded superconducting cavity-qubit system in the strong dispersive regime in a setup similar to recent experiments. In the presence of dissipation, we find that an effective Hartree-type decoupling with a Fokker-Planck equation yields a good approximation. We find that the stationary state is approximately a squeezed vacuum, which is enhanced by the $Q$-factor of the cavity but conserved by the interaction. The qubit non-linearity, therefore, does not significantly influence the highly squeezed intracavity microwave field but, for a range of realistic parameters, enables characterisation of itinerant squeezed fields.

description: Polar codes are the latest breakthrough in coding theory, as they are the first family of codes with explicit construction that provably achieve the symmetric capacity of discrete memoryless channels. Arıkan's polar encoder and successive cancellation decoder have complexities of $N \log N$, for code length $N$. Although, the complexity bound of $N \log N$ is asymptotically favorable, we report in this work methods to further reduce the encoding and decoding complexities of polar coding. The crux is to relax the polarization of certain bit-channels without performance degradation. We consider schemes for relaxing the polarization of both \emph{very good} and \emph{very bad} bit-channels, in the process of channel polarization. Relaxed polar codes are proved to preserve the capacity achieving property of polar codes. Analytical bounds on the asymptotic and finite-length complexity reduction attainable by relaxed polarization are derived. For binary erasure channels, we show that the computation complexity can be reduced by a factor of 6, while preserving the rate and error performance. We also show that relaxed polar codes can be decoded with significantly reduced latency. For AWGN channels with medium code lengths, we show that relaxed polar codes can have lower error probabilities than conventional polar codes, while having reduced encoding and decoding computation complexities.

description: We discuss conserved currents constructed from the Cotton tensor and (conformal) Killing-Yano tensors (KYTs). We consider the corresponding charges generally and then exemplify with the four-dimensional Plebański-Demiański metric where they are proportional to the sum of the squares of the electric and the magnetic charges. As part of the derivation, we also find the two conformal Killing-Yano tensors of the Plebański-Demiański metric in the recently introduced coordinates of Podolsky and Vratny. The construction of asymptotic charges for the Cotton current is elucidated and compared to the three-dimensional construction in Topologically Massive Gravity. For the three-dimensional case, we also give a conformal superspace multiplet that contains the Cotton current in the bosonic sector. In a mathematical section, we derive potentials for the currents, find identities for conformal KYTs and for KYTs in torsionful backgrounds.

description: Background: Behçet’s disease (BD) is a variable-vessel vasculitis with a distinct geographical distribution of high prevalence along the ancient Silk Route, extending from eastern Asia to the Mediterranean. The prevalence and incidence rate in southern Sweden have previously been estimated to 4.9 per 100,000 adults and 0.2 per 100,000 person-years, respectively. Since then, the proportion of the population of non-Swedish ancestry has increased in southern Sweden. Furthermore, immigration patterns might have an increasing influence on epidemiology of BD. This study is aimed to update the epidemiology of BD in southern Sweden. Methods: The study area was the county of Skåne with an adult (≥18 years) population of 1 080 664 on 31st of December 2019. Patients assigned to the ICD-10 code M35.2 between 1998 and 2019 were retrospectively identified by search in population-based data base. Patients fulfilling the International Study Group diagnostic criteria for BD were included. The point prevalence per 100 000 adults was estimated on the 31st of December 2019. Incidence rate of BD was estimated per 100 000 adult person-years. Non-Swedish ancestry was defined as a person being born outside of Sweden or with two parents born outside of Sweden. A case was considered incident when the diagnosis was made within Skåne with a minimum of 3 years of residence in Sweden prior to diagnosis. Results: 101 patients fulfilling the diagnostic criteria for BD were identified (61 men and 40 women). The point prevalence was 9.1/100 000 adults (95% CI 7.3, 10.9) and higher among the population of non-Swedish ancestry (19.3 vs. 4.8/100 000, p = 0.001) and higher among men (11.2 vs 7.0/100 000, p =0.027). There were 58 adult incident cases diagnosed between 1998 and 2019. The incidence rate was 0.3/100 000 person-years (95% CI 0.2,0.3) and was higher among the population of non-Swedish ancestry 0.7 vs. 0.2/100 000, p =0.001). There was no significant increase in incidence rate of BD over time (Table 1). All patients presented with oral ulcerations, 90% with genital ulcerations, 84% with skin lesions and 53% with eye disease. 18% experienced thromboembolic events, 14 men and 4 women. Conclusions: The prevalence of BD in southern Sweden has increased since last estimated. The incidence rate of BD has not increased significantly during the study period, despite an increased proportion of the population being of non-Swedish ancestry. Although the study was in a population-based setting the low sample size is a limitation. Disclosures: None.
title: A study on the changes of everyday space as a worker in the city: focusing on the drawing series [Li:ving] London
Creators: name: Roh, Jung Yuh
Publisher: name: University of Reading
Year: 2022

description: This practice-led research presupposes my autobiographical living experience in London, England, focusing on the drawing project [Li:ving] London (2016-2018). My research question revolves around how the art project recreates the value of everyday life and individuals’ subjectivity in a post-capitalist society. The significance of this research is to overcome human alienation, as a worker and an artist, and reveal the individual’s independent existence and experience. I have selected the sandwich franchise Pret A Manger and my commuting route in London as the primary subject matter. Borrowing Michel Foucault’s spatial concept of Heterotopia, I considered the franchise cafe and my commuting route as heterotopia. Based on my subjective experience as a manual worker, the artistic practice of walking and daily drawing is deployed as the main methodologies. Through repetitive walking and drawing, the most basic artistic labour, I found subtle variations in urban spaces. As time went on, the repetitive itinerary allowed for the drawing images to be more abstract and unrealistic. Social media and five exhibitions are followed by the art practice as the way of presentation methods. I aim to independently reconstruct a new subjective identity and present the drawings and exhibitions along with social media as research outcomes, which show the endeavour to answer this question. The outcomes of this research are presented in two parts, the thesis text and the documentation of the work and exhibitions.

description: The smallest set of admissible parameters of a $q$-analog of a Steiner system is $S_2[2,3,7]$. The existence of such a Steiner system -- known as a binary $q$-analog of the Fano plane -- is still open. In this article, the automorphism group of a putative binary $q$-analog of the Fano plane is investigated by a combination of theoretical and computational methods. As a conclusion, it is either rigid or its automorphism group is cyclic of order $2$, $3$ or $4$. Up to conjugacy in $\operatorname{GL}(7,2)$, there remains a single possible group of order $2$ and $4$, respectively, and two possible groups of order $3$. For the automorphisms of order $2$, we give a more general result which is valid for any binary $q$-Steiner triple system.

description: The drag and diffusion coefficients of heavy quarks (HQs) have been evaluated in the pre-equilibrium phase of the evolving fireball produced in heavy ion collisions at RHIC and LHC energies. The KLN and classical Yang-Mills spectra have been used for describing the momentum distributions of the gluons produced just after the collisions but before they thermalize. The interaction of the HQs with these gluons has been treated within the framework of perturbative QCD. We have observed that the HQs are dragged almost equally by the kinetically equilibrated and out-of-equilibrium gluonic systems. We have also noticed that the HQs diffusion in the pre-equilibrium gluonic phase is as fast as in the kinetically equilibrated gluons. Moreover, the diffusion is faster in the pre-equilibrium phase than in the chemically equilibrated quark-gluon plasma. These findings may have significant impact on the analysis of experimental results on the elliptic flow and the high momentum suppression of the open charm and beauty hadrons.

description: Depending on the node ordering, an adjacency matrix can highlight distinct characteristics of a graph. Deriving a "proper" node ordering is thus a critical step in visualizing a graph as an adjacency matrix. Users often try multiple matrix reorderings using different methods until they find one that meets the analysis goal. However, this trial-and-error approach is laborious and disorganized, which is especially challenging for novices. This paper presents a technique that enables users to effortlessly find a matrix reordering they want. Specifically, we design a generative model that learns a latent space of diverse matrix reorderings of the given graph. We also construct an intuitive user interface from the learned latent space by creating a map of various matrix reorderings. We demonstrate our approach through quantitative and qualitative evaluations of the generated reorderings and learned latent spaces. The results show that our model is capable of learning a latent space of diverse matrix reorderings. Most existing research in this area generally focused on developing algorithms that can compute "better" matrix reorderings for particular circumstances. This paper introduces a fundamentally new approach to matrix visualization of a graph, where a machine learning model learns to generate diverse matrix reorderings of a graph.

description: In this paper we propose a novel approach to generate a synthetic aerial dataset for application in UAV monitoring. We propose to accentuate shape-based object representation by applying texture randomization. A diverse dataset with photorealism in all parameters such as shape, pose, lighting, scale, viewpoint, etc. except for atypical textures is created in a 3D modelling software Blender. Our approach specifically targets two conditions in aerial images where texture of objects is difficult to detect, namely challenging illumination and objects occupying only a small portion of the image. Experimental evaluation of YOLO and Faster R-CNN detectors trained on synthetic data with randomized textures confirmed our approach by increasing the mAP value (17 and 3.7 percentage points for YOLO; 20 and 1.1 percentage points for Faster R-CNN) on two test datasets of real images, both containing UAV-to-UAV images with motion blur. Testing on different domains, we conclude that the more the generalisation ability is put to the test, the more apparent are the advantages of the shape-based representation.

title: Building Bridges Towards Self-regulation: The Goal-Setting Behaviour of Adult Language Learners in MOOCs
Creators: name: Conde Gafaro, Barbara
Publisher: name: The Open University
Year: 2022

description: Massive Open Online Courses (MOOCs) offer educational opportunities to a wide range of learners. Language learners can use these courses to develop knowledge and practise language skills needed daily or in different areas of specialisation. However, learners may not benefit from this learning opportunity if they do not know how to self-regulate their learning. Self-regulated learners employ various processes to master their learning and accomplish their goals. The literature shows that goal setting is a helpful self-regulatory process that contributes to a successful MOOC learning experience. Goal setting is the driving force behind any educational intention and can provide the basis for a strategic plan formulated by learners at the start of a learning task. Moreover, this self-regulatory process holds the key to activating, monitoring, and assessing an effective learning process. Nonetheless, goal-setting support in these online courses is scarce. Research on goal setting in MOOCs has not previously investigated the personal learning goals that learners bring to these non-formal learning environments. This represents a twofold omission in the field of Computer-Assisted Language Learning (CALL), in which MOOCs are themselves an under-researched area. Although CALL practitioners have gradually integrated MOOCs into the L2 classroom, little research has examined adult learners' goals during their MOOC-based learning. To address this gap in the literature, this research uncovers the goal-setting behaviour of 19 adult learners who studied MOOCs for four weeks as part of their classroom-based language courses. To achieve this aim, the researcher gathered and analysed 38 semi-structured interviews, 71 weekly monitoring surveys, 19 open-ended questionnaires and 19 MOOC screenshots. The findings of this study advance the field of CALL by providing a comprehensive picture of the different aspects of language, traditional and non-traditional goals, and MOOC elements involved when L2 adult learners self-regulate their learning online.

description: We explain how twistor theory represents the self-dual sector of four dimensional gravity in terms of the loop group of Poisson diffeomorphisms of the plane via Penrose's non-linear graviton construction. The symmetries of the self-dual sector are generated by the corresponding loop algebra $Lw_{1+\infty}$ of the algebra $w_{1+\infty}$ of these Poisson diffeomorphisms. We show that these coincide with the infinite tower of soft graviton symmetries in tree-level perturbative gravity recently discovered in the context of celestial amplitudes. We use a twistor sigma model for the self-dual sector which describes maps from the Riemann sphere to the asymptotic twistor space defined from characteristic data at null infinity ${\mathcal I}$. We show that the OPE of the sigma model naturally encodes the Poisson structure on twistor space and gives rise to the celestial realization of $Lw_{1+\infty}$. The vertex operators representing soft gravitons in our model act as currents generating the wedge algebra of $w_{1+\infty}$ and produce the expected celestial OPE with hard gravitons of both helicities. We also discuss how the two copies of $Lw_{1+\infty}$, one for each of the self-dual and anti-self-dual sectors, are represented in the OPEs of vertex operators of the 4d ambitwistor string.

description: We present the validation of ADBSat, a novel implementation of the panel method including a fast pseudo-shading algorithm, that can quickly and accurately determine the forces and torques on satellites in free-molecular flow. Our main method of validation is comparing test cases between ADBSat, the current de facto standard of direct simulation Monte Carlo (DSMC), and published literature. ADBSat exhibits a significantly shorter runtime than DSMC and performs well, except where deep concavities are present in the satellite models. The shading algorithm also experiences problems when a large proportion of the satellite surface area is oriented parallel to the flow, but this can be mitigated by examining the body at small angles to this configuration (${\pm}$ 0.1°). We recommend that an error interval on ADBSat outputs of up to 3\% is adopted. Therefore, ADBSat is a suitable tool for quickly determining the aerodynamic characteristics of a wide range of satellite geometries in different environmental conditions in VLEO. It can also be used in a complementary manner to identify cases that warrant further investigation using other numerical-based methods.

description: Using an effective field theory we describe the low energy bosonic excitations in a three dimensional ultra-cold mixture of spin-1 bosons and spin-1/2 fermions. We establish an interesting fermionic excitation induced generic damping of the usual undamped long wavelength bosonic collective Goldstone modes. Two states with bosons forming either a ferromagnetic or polar superfluid are studied. The linear dispersion of the bosonic Bogoliubov excitations is preserved with a renormalized sound velocity. For the polar superfluid we find both gapless modes (density and spin) are damped, whereas in the ferromagnetic superfluid we find the density (spin) mode is (not) damped. We argue quite generally that this holds for any mixture of bosons and fermions that are coupled through at least a density-density interaction. We discuss the implications of our many-body interaction results for experiments on Bose-Fermi mixtures.

description: This work continues the parametric investigation on the sampling nuances of the Dynamic Mode Decomposition (DMD) under the Koopman analysis. Through turbulent wakes, the investigation corroborated the generality of the universal convergence states for all DMD implementations. It discovered the implications of sampling range and resolution -- the determinants of the spectral discretisation by discrete frequency bins and the highest resolved frequency, respectively. The work reaffirmed the necessity of the Convergence state for sampling independence, too. Results also suggested that the observables derived from the same flow may contain dynamically distinct information, thus altering the DMD output. The static pressure and vortex identification criteria are optimal variables for characterising structural response and fluid excitation. The pressure, velocity magnitude, and turbulence kinetic energy fields also suffice for general applications, but the Reynolds stresses and velocity components shall be avoided. Mean-subtraction is recommended for best approximations of the Koopman eigen tuples. Furthermore, the parametric investigation on truncation discovered some low-energy states that dictate a system's temporal integrity. The best practice for order reduction is to avoid truncation and employ dominant mode selection on a full-state subspace, though large-degree truncation supports fair data reconstruction with low computational cost. Finally, this work demonstrated the synthetic noise resulting from pre-decomposition interpolation. In unavoidable interpolations to increase the spatial dimension n, high-order schemes are recommended for better retention of the original dynamics. Finally, the observations herein, derived from inhomogeneous anisotropic turbulence, offer constructive references for DMD on fluid systems, if not also others beyond fluid mechanics.

description: The main disadvantage of Magnetic Resonance Imaging (MRI) are its long scan times and, in consequence, its sensitivity to motion. Exploiting the complementary information from multiple receive coils, parallel imaging is able to recover images from under-sampled k-space data and to accelerate the measurement. Because parallel magnetic resonance imaging can be used to accelerate basically any imaging sequence it has many important applications. Parallel imaging brought a fundamental shift in image reconstruction: Image reconstruction changed from a simple direct Fourier transform to the solution of an ill-conditioned inverse problem. This work gives an overview of image reconstruction from the perspective of inverse problems. After introducing basic concepts such as regularization, discretization, and iterative reconstruction, advanced topics are discussed including algorithms for auto-calibration, the connection to approximation theory, and the combination with compressed sensing.

description: The Majorana phase boundaries in planar 2D hybrid (semiconductor-superconductor) nanowires are modified by orbital effects due to off plane magnetic components. We show that Majorana zero modes survive sizable vertical field tiltings, uncovering a remarkable phase diagram. Analytical expressions of the phase boundaries are given for the strong orbital limit. These phase boundaries can be fulfilled with attainable setups, such as an InAs nanowire of $150\, {\rm nm}$ in transverse width.

description: Traffic forecasting is a challenging problem due to complex road networks and sudden speed changes caused by various events on roads. A number of models have been proposed to solve this challenging problem with a focus on learning spatio-temporal dependencies of roads. In this work, we propose a new perspective of converting the forecasting problem into a pattern matching task, assuming that large data can be represented by a set of patterns. To evaluate the validness of the new perspective, we design a novel traffic forecasting model, called Pattern-Matching Memory Networks (PM-MemNet), which learns to match input data to the representative patterns with a key-value memory structure. We first extract and cluster representative traffic patterns, which serve as keys in the memory. Then via matching the extracted keys and inputs, PM-MemNet acquires necessary information of existing traffic patterns from the memory and uses it for forecasting. To model spatio-temporal correlation of traffic, we proposed novel memory architecture GCMem, which integrates attention and graph convolution for memory enhancement. The experiment results indicate that PM-MemNet is more accurate than state-of-the-art models, such as Graph WaveNet with higher responsiveness. We also present a qualitative analysis result, describing how PM-MemNet works and achieves its higher accuracy when road speed rapidly changes.

description: We investigate the prediction of the turbulent flow around a canonical square cylinder at Re= 22000 solving the unsteady Reynolds-averaged Navier-Stokes (URANS) equations. The limitations of URANS modelling are overcome through the application of a data assimilation technique involving a feedback control term, allowing to drive the URANS predictions towards reference data. Using regularly-spaced temporally-resolved reference data that are extracted from DNS, we assess the abilities of the data assimilation methodology in improving the unsteady URANS predictions. While improving the low-frequency oscillations of the wake flow, we also demonstrate the ability to recover the high-frequency dynamics of Kelvin-Helmholtz instabilities. The influence of spatial resolution of reference data is systematically investigated. The data resolution which is required to improve the prediction of flow structures of interest is related to their wavelength. Using a spacing of the order of one cylinder length between data points, we already observe synchronisation of the low-frequency vortex shedding that leads to a significant decrease in temporal and spectral errors as computed by spectral proper orthogonal decomposition. Furthermore,improved accuracy in terms of mean flow prediction of URANS is achieved. Using spacing of the order of the wavelength of the Kelvin-Helmholtz vortices, we even recover those shear layer structures which are absent in the baseline simulation.

description: The article is devoted to one of the Russian-German phrasebooks from the 16–17th centuries, compiled for contacts of Russian and Hanseatic merchants. In the manuscript under consideration are to find the name Thomas Schrowe as scribe and the year 1546. Till now was the understanding, that the book was written in the end of the fifteenth century for the mayor of the town Dorpat in Livonia with this name (he did before 1501) and that 1546 was the date of a copy. However, it is possible to demonstrate, that another Thomas Schrowe from Dorpat was a young man in 1546, later a town-councilor and connoisseur of the Russian language. Without doubt, he was the author of the manuscript from 1546, and this book is a source primarily for the Russian-Hanseatic contacts (particular in Pskov) in the first half of the sixteenth century. The text of Schrowe has a not preserved common source from this time with the better known phrasebook of the Lübeck merchant Tönnies Fonne. These books with subject lists of words and conversational dialogues in Russian and German languages are priceless sources not only for the Russian folk language, but also for the practice of trade and the predominant friendly contacts of the Russian and German merchants.
description: Статья посвящена одному из русско-немецких разговорников XVI– XVII вв., созданных для контактов русских и ганзейских купцов. В этой рукописи можно найти имя Томаса Шрове, писца, и упоминание даты 1546 г. До сих пор полагали, что книга записана в конце XVI в. для бургомистра ливонского города Дорпат с таким именем и такой фамилией (он умер до 1501 г. г.), и что 1546 г. — это дата создания копии. Однако есть возможность показать, что другой Томас Шрове из Дорпата, который был в 1546 г. молодым юношей, позже был засвидетельствован как член городского совета и знаток русского языка. Без сомнения, именно он был автором рукописи 1546 г., и эта книга является главным источником главным образом для анализа русско-ганзейских контактов первой половины XVI в. (особенно в Пскове). Несохранившийся текст этого периода служил общей основой для книги Шрове и для более известного разговорника любекского купца Тонниса Фонна. Эти книги с тематическими словарями и диалогами на русском и немецком языках — бесценные источники не только для русского народного языка, но и для изучения торговой практики и в целом дружественных контактов между русскими и немецкими купцами.
