description: Shocks of supernova remnants (SNRs) accelerate charged particles up to 100 TeV range via diffusive shock acceleration (DSA) mechanism. It is believed that shocks of SNRs are the main contributors to the pool of Galactic cosmic rays, although it is still under debate whether they can accelerate particles up to the "knee" energy (10^15.5 eV) or not. In this chapter, we start with introducing SNRs as likely sources of cosmic rays and the radiation mechanisms associated with cosmic rays (section 3). In the section 4, we summarize the mechanism for particle acceleration, including basic diffusive shock acceleration and nonlinear effects, as well as discussing the injection problem. Section 5 is devoted to the X-ray and gamma-ray observations of nonthermal emission from SNRs, and what these reveal about the cosmic-ray acceleration properties of SNRs.

A second Higgs near 0.5 TeV from bottom-up holographic modeling of beyond the Standard Model strong sector

description: One of the simplest extensions of the Standard Model (SM) consists in adding a scalar singlet. This second Higgs boson is able to solve several fundamental problems of SM. Additional scalar particles arise naturally in composite Higgs scenarios in which some confining "strong sector" beyond the SM drives the electroweak symmetry breaking. The underlying strongly coupled gauge theory may be similar to QCD and could be modeled holographically. We construct a bottom-up holographic model for description of the spectrum of composite Higgs particles. The model is based on the holographic Soft Wall model and the Wilson confinement criterion. The constructed model predicts the existence of a second Higgs boson with a mass of about 515 GeV.

Dipole-induced localized plasmon modes and resonant surface plasmon scattering

description: A metal film supports the continuum of propagating surface plasmon waves. The interaction of these waves with a dipole (nanoparticle) positioned some distance from the surface of the film can produce well defined localized plasmon modes whose frequency nonetheless resides inside the continuum. This leads to the resonant enhancement of scattering of surface plasmons off the dipole. The maximum of scattering is found to occur when the distance from the dipole to the surface of the film is equal to one half of the film thickness. The possibility of controllable plasmon scattering could be advantageous for the field of nanoplasmonics.

description: Machine-type communication requires the infrastructure of the cellular network to adequately function. Therefore the need to share the same random access channel (RACH) with other communication devices poses a serious challenge considering the massive nature of machine-type communication devices (MTCDs). The current setup of access requests through the random access (RA) process is known to suffer congestion and network overload due to the variability of MTCDs. Data aggregation could be used to resolve the high collision rate by reducing the access request to the base station. However, this may introduce an excessive delay for the MTCDs. To solve this problems, we propose a clustered-based data aggregation access scheme (CDAAS) which reduces the access request to the base station while increasing the access success proportion of MTCDs. The proposed scheme utilizes MTCD clustering as well as effective data aggregation to increase access success proportion while meeting the delay requirement of the various MTCDs. Based on simulation results, our proposed scheme significantly outperforms the typical access schemes such as access class barring (ACB) in terms of access delay and access success proportion.

description: Low-frequency vibrational harmonic modes of glasses are frequently used to understand their universal low-temperature properties. One well studied feature is the excess low-frequency density of states over the Debye model prediction. Here we examine the system size dependence of the density of states for two-dimensional glasses. For systems of fewer than 100 particles, the density of states scales with the system size as if all the modes were plane-wave-like. However, for systems greater than 100 particles we find a different system-size scaling of the cumulative density of states below the first transverse sound mode frequency, which can be derived from the assumption that these modes are quasi-localized. Moreover, for systems greater than 100 particles, we find that the cumulative density of states scales with frequency as a power law with the exponent that leads to the exponent $β=3.5$ for the density of states independent of system size.

description: The aim of this paper is to study some parameters of simple graphs related with the degree of the vertices.

We study the Randić index and some interesting particular cases of conditional excess, conditional Wiener index, and conditional diameter. In particular, using the matrix ${\cal A}$ or its eigenvalues, we obtain tight bounds on the studied parameters.

description: The 1+1D O(3) non-linear σ-model is a model system for future quantum lattice simulations of other asymptotically-free theories, such as non-Abelian gauge theories. We find that utilizing dimensional reduction can make efficient use of two-dimensional layouts presently available on cold atom quantum simulators. A new definition of the renormalized coupling is introduced, which is applicable to systems with open boundary conditions and can be measured using analog quantum simulators. Monte Carlo and tensor network calculations are performed to determine the quantum resources required to reproduce perturbative short-distance observables. In particular, we show that a rectangular array of 48 Rydberg atoms with existing quantum hardware capabilities should be able to adiabatically prepare low-energy states of the perturbatively-matched theory. These states can then be used to simulate non-perturbative observables in the continuum limit that lie beyond the reach of classical computers.

description: Abstract

This study examines the role of work engagement in bridging the influence of organizational justice and self-efficacy on organizational citizenship behavior. The respondents of this study were hospital nurses in Kendari city as many as 413 people. Testing the structural model developed in this study using Analysis of Moment Structure (AMOS) and Statistical Program for Social Science (SPSS) version 22, both of which are statistical tools from IBM. The test results show that work engagement has a significant role in strengthening the relationship of organizational justice and self efficacy to organizational citizenship behavior. This study also found that work engagement can be an effective catalyst for the relationship between self efficacy and organizational citizenship behavior. The findings of this study can contribute to strengthening social learning theory, especially in the context of the causal relationship between organizational justice, self efficacy, work engagement, and organizational citizenship behavior. In addition, this study can contribute to hospital management in Kendari City in implementing and developing human resource management strategies, especially for nurses in hospitals.

description: The crystal structure, resistivity, and magnetic susceptibility of the Li2Ir1-xRuxO3 (x = 0-1) polycrystals have been investigated. We found that the parent antiferromagnetic phase disappears for x > 0.2 and bond dimers appear in the averaged structure for x > 0.5 and likely fluctuate for much smaller x. Unexpectedly, this system remains insulating for all the doping levels, in sharp contrast with the robust metallic state found in Sr2Ir1-xRuxO4. These results demonstrate that the essential physics of the doped A2IrO3 (A = Li, Na) system deviates significantly from the common one-band jeff=1/2 spin-orbit model.

Analyzing the Relationship Between Crime and Small Business Lending: Considering Lending from a Credit Risk Perspective
Creators: name: Clark, Daria
Publisher: name: University of Chicago
Year: 2022

description: Small businesses serve important functions in the communities in which they serve. These businesses tend to rely on external sources of financing, such as loans, to operate and expand. Thus, it is important to consider variables that may impact the loans they receive. In studies and discussions about how certain variables influence business lending, income and race are two that have been largely focused on. One less discussed variable has been crime. This analysis aims to understand the relationship between crime and lending. The motivation for analyzing crime comes from thinking of lending from a credit risk perspective. Crime imposes costs to local businesses and thus threatens their viability. In turn, this may make lenders hesitant to lend, meaning that crime can negatively influence lending. The analysis studies Chicago community areas and finds evidence that crime does have a negative relationship with lending. In turn, it is recommended that policymakers promote and enhance lending incentive programs, such as the New Markets Tax Credit (NMTC) Program, in an effort to encourage lending by rewarding lenders for the risks they take on.

description: Texture zeros in fermion mass matrices have been widely considered in tackling the Standard Model flavour puzzle. In this work, we perform a systematic analysis of texture zeros in lepton mass matrices in the framework of $Γ_{3}'\cong T'$ modular symmetry. Assuming that the lepton fields transform as irreducible representations of $T'$, we obtain all possible texture-zero patterns for both charged-lepton and neutrino mass matrices which can be achieved from $T'$ modular symmetry. We provide representative models for the phenomenologically-viable textures which can accommodate the experimental data. The predictions for lepton mixing angles, CP-violating phases, light neutrino masses and effective neutrino mass relevant for neutrinoless doble beta decay, are discussed. We find that the minimal viable lepton model depends on only $7$ real free parameters including the modulus $τ$ (the corresponding charged-lepton mass matrix contains $4$ vanishing entries, and the neutrino mass matrix has $1$ texture zero). Finally, we study in detail three benchmark models, one for each neutrino mass generation mechanism considered (Dirac, Majorana via Weinberg operator and Majorana via minimal type-I seesaw mechanism).

description: Low-frequency noise can induce serious decoherence in superconducting qubits. Due to its diverse physical origin, such noise can couple with the qubits either as transverse or as longitudinal noise. Here, we present a universal quantum degeneracy point approach that can protect an encoded qubit from arbitrary low-frequency noise. We further show that universal quantum logic gates can be performed on the encoded qubits with high fidelity. The proposed scheme can be readily implemented with superconducting flux qubits or with a qubit coupling with a superconducting resonator. Meanwhile, the scheme is also robust against small parameter spreads due to fabrication errors in the superconducting systems.

By utilizing the inequalities with the maximum and minimum of the solution related to the first three conservation laws, we establish that the periodic peakons of this equation are orbitally stable under small perturbations in the energy space.

description: The predicted orbital-period distribution of the subdwarf-B (sdB) population is bi-modal with a peak at short (< 10 days) and long (> 250 days) periods. Observationally, many short-period sdB systems are known, but the predicted long period peak is missing as orbits have only been determined for a few long-period systems. As these predictions are based on poorly understood binary-interaction processes, it is of prime importance to confront the predictions with reliable observational data. We therefore initiated a monitoring program to find and characterize long-period sdB stars. In this paper we aim to determine the orbital parameters of the three long-period sdB+MS binaries BD+29 3070, BD+34 1543 and Feige 87, to constrain their absolute dimensions and the physical parameters of the components. High-resolution spectroscopic time series were obtained with HERMES at the Mercator telescope on La Palma, and analyzed to determine the radial velocities of both the sdB and MS components. Photometry from the literature was used to construct the spectral-energy distribution (SED) of the binaries. Atmosphere models were used to fit these SEDs and to determine the surface gravities and temperatures of both components of all systems. Spectral analysis was used to check the results of the SEDs. An orbital period of 1283 +- 63 d, a mass ratio of q = 0.39 +- 0.04 and a significant non-zero eccentricity of e = 0.15 +- 0.01 were found for BD+29 3070. For BD+34 1543 we determined P = 972 +- 2 d, q = 0.57 +- 0.01 and again a clear non-zero eccentricity of e = 0.16 +- 0.01. Last, for Feige 87 we found P = 936 +- 2 d, q = 0.55 +- 0.01 and e = 0.11 +- 0.01. BD+29 3070, BD+34 1543 and Feige 87 are long period sdB + MS binaries on clearly eccentric orbits. These results are in conflict with the predictions of stable Roche-lobe overflow models.

description: Wer gesundheitliche Folgen von Gewalt nachweisen kann, hat in Deutschland Anspruch auf die Übernahme von Heilbehandlung sowie Rentenleistungen durch den Staat. Opferentschädigung kommt allerdings nur Wenigen zugute. In einer Analyse aller im Jahr 2008 abgeschlossenen Akten (n=209) zum Opferentschädigungsgesetz (OEG) aus der Versorgungsregion Fulda und ergänzenden Experteninterviews wurde untersucht, ob die gesetzlichen Grundlagen und die Verfahrenspraxis zu einer strukturellen Chancengleichheit beider Geschlechter auf Entschädigung führen. Unter den in der Polizeistatistik erfassten Gewalttaten sind Männer eher von Gewalt im öffentlichen Raum, Frauen eher von familiärer beziehungsweise Partnergewalt betroffen. Opfer familiärer und Partnergewalt waren unter den Anträgen nach dem OEG unterrepräsentiert. Rechtliche Regelungen und die Verfahrenspraxis verringern Erfolgschancen eines Antrags bei familiärer beziehungsweise Partnergewalt. Dies spricht für eine strukturelle Benachteiligung von Frauen.

description: We revisit the random tree model with nearest-neighbour interaction as described in previous work, enhancing growth. When the underlying free Bienaymé-Galton-Watson (BGW) model is sub-critical, we show that the (non-Markov) model with interaction exhibits a phase transition between sub- and super-critical regimes. In the critical regime, using tools from dynamical systems, we show that the partition function of the model approaches a limit at rate $n^{-1}$ in the generation number $n$. In the critical regime with almost sure extinction, we also prove that the mean number of external nodes in the tree at generation $n$ decays like $n^{-2}$. Finally, we give a spin representation of the random tree, opening the way to tools from the theory of Gibbs states, including FKG inequalities. We extend the construction in previous work when the law of the branching mechanism of the free BGW process has unbounded support.

description: Global climate models aim to reproduce physical processes on a global scale and predict quantities such as temperature given some forcing inputs. We consider climate ensembles made of collections of such runs with different initial conditions and forcing scenarios. The purpose of this work is to show how the simulated temperatures in the ensemble can be reproduced (emulated) with a global space/time statistical model that addresses the issue of capturing nonstationarities in latitude more effectively than current alternatives in the literature. The model we propose leads to a computationally efficient estimation procedure and, by exploiting the gridded geometry of the data, we can fit massive data sets with millions of simulated data within a few hours. Given a training set of runs, the model efficiently emulates temperature for very different scenarios and therefore is an appealing tool for impact assessment.

description: Infrared (IR) absorption spectra of individual polycyclic aromatic hydrocarbons (PAHs) containing methyl (-CH3), methylene (>CH2), or diamond-like *CH groups and IR spectra of mixtures of methylated and hydrogenated PAHs prepared by gas phase condensation were measured at room temperature (as grains in pellets) and at low temperature (isolated in Ne matrices). In addition, the PAH blends were subjected to an in-depth molecular structure analysis by means of high-performance liquid chromatography, nuclear magnetic resonance spectroscopy, and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Supported by calculations at the density functional theory level, the laboratory results were applied to analyze in detail the aliphatic absorption complex of the diffuse interstellar medium at 3.4 mu-m and to determine the abundances of hydrocarbon functional groups. Assuming that the PAHs are mainly locked in grains, aliphatic CHx groups (x = 1,2,3) would contribute approximately in equal quantities to the 3.4 mu-m feature (N_{CHx} / N_{H} approx 10^{-5} - 2 * 10^{-5}). The abundances, however, may be two to four times lower if a major contribution to the 3.4 mu-m feature comes from molecules in the gas phase. Aromatic =CH groups seem to be almost absent from some lines of sight, but can be nearly as abundant as each of the aliphatic components in other directions (N_{=CH} / N_{H} < 2 * 10^{-5}; upper value for grains). Due to comparatively low binding energies, astronomical IR emission sources do not display such heavy excess hydrogenation. At best, especially in proto-planetary nebulae, >CH2 groups bound to aromatic molecules, i.e., excess hydrogens on the molecular periphery only, can survive the presence of a nearby star.

description: We present the results of a numerical adaptive mesh refinement hydrodynamical and N-body simulation in a $ΛCDM$ cosmology. We focus on the analysis of the main properties of massive galaxies ($M_* > 10^{11}\,M_{\odot}$) at $z=0$. For all the massive virtual galaxies we carry out a careful study of their one dimensional density, luminosity, velocity dispersion, and stellar population profiles. In order to best compare with observational data, the method to estimate the velocity dispersion is calibrated by using an approach similar to that performed in the observations, based on the stellar populations of the simulated galaxies. With these ingredients, we discuss the different properties of massive galaxies in our sample according to their morphological types, accretion histories and dynamical properties. We find that the galaxy merging history is the leading actor in shaping the massive galaxies that we see nowadays. Indeed, galaxies having experienced a turbulent life are the most massive in the sample and show the steepest metallicity gradients. Beside the importance of merging, only a small fraction of the final stellar mass has been formed ex-situ (10-50%), while the majority of the stars formed within the galaxy. These accreted stars are significantly older and less metallic than the stars formed in-situ and tend to occupy the most external regions of the galaxies.

description: In this work, we use the results from Higgs searches in the $γγ$ and $ττ$ decay channels at LHC and indirect bounds as BR$(B \to X_s γ)$ to constrain the parameter space of a generic MSSM Higgs sector. In particular, we include the latest CMS results that look for additional Higgs states with masses up to 1 TeV. We show that the $ττ$ channel is the best and most accurate weapon in the hunt for new Higgs states beyond the Standard Model. We obtain that present experimental results rule out additional neutral Higgs bosons in a generic MSSM below 300 GeV for any value of $\tan β$ and, for instance, values of $\tan β$ above 30 are only possible for Higgs masses above 600 GeV. ATLAS stored data has the potential to render this bound obsolete in the near future.

description: The gravitational waves from the binary neutron star merger GW170817 were accompanied by a multi-wavelength electromagnetic counterpart, which confirms the association of the merger with a short gamma-ray burst (sGRB). The afterglow observations implied that the event was accompanied by a narrow, $\sim 5~$deg, and powerful, $\sim 10^{50}$ erg, jet. We study the propagation of a Poynting flux-dominated jet within the merger ejecta (kinematic, neutrino-driven and MRI turbulence-driven) of a neutrino-radiation-GR-MHD simulation of two coalescing neutron stars. We find that the presence of a post-merger low-density/low-pressure polar cavity, that arose due to angular momentum conservation, is crucial to let the jet break out. At the same time the ejecta collimates the jet to a narrow opening angle. The collimated jet has a narrow opening angle of $\sim 4$-$7$ deg and an energy of $10^{49}$-$10^{50}~$erg, in line with the observations of GW170817 and other sGRBs.

description: We compile a sample of X-ray-selected galaxy groups and clusters from the XMM-Newton serendipitous source catalogue (2XMMi-DR3) with optical confirmation and redshift measurement from the Sloan Digital Sky Survey (SDSS). The X-ray cluster candidates were selected from the 2XMMi-DR3 catalogue in the footprint of the SDSS-DR7. We developed a finding algorithm to search for overdensities of galaxies at the positions of the X-ray cluster candidates in the photometric redshift space and to measure the redshifts of the clusters from the SDSS data. The detection algorithm provides the photometric redshift of 530 galaxy clusters. Of these, 310 clusters have a spectroscopic redshift for at least one member galaxy. About 75 percent of the optically confirmed cluster sample are newly discovered X-ray clusters. Moreover, 301 systems are known as optically selected clusters in the literature while the remainder are new discoveries in X-ray and optical bands. The optically confirmed cluster sample spans a wide redshift range 0.03-0.70 (median z=0.32). In this paper, we present the catalogue of X-ray-selected galaxy groups and clusters from the 2XMMi/SDSS galaxy cluster survey. The catalogue has two subsamples: (i) a cluster sample comprising 345 objects with their X-ray spectroscopic temperature and flux from the spectral fitting, and (ii) a cluster sample consisting of 185 systems with their X-ray flux from the 2XMMi-DR3 catalogue, because their X-ray data are insufficient for spectral fitting. The updated L_X-T relation of the current sample with X-ray spectroscopic parameters is presented. We see no evidence for evolution in the slope and intrinsic scatter of the L_X-T relation with redshift when excluding the low-luminosity groups.

description: We present a lattice study of the $SU(4)$ gauge theory with two Dirac fermions in the fundamental and two in the two-index antisymmetric representation, a model close to a theory of partial compositeness. Focus of this work are the methodologies behind the computation of the spectrum and the extrapolation of the chiral point for a theory with matter in multiple representations. While being still technical, this study provides important steps towards a non-perturbative understanding of the spectrum of theories of partial compositeness, which present a richer dynamics compared to single-representation theories. The multi-representation features are studied first in perturbation theory, and then non-perturbatively by adopting a dual outlook on lattice data through a joint analysis of time-momentum correlation functions and smeared spectral densities.
title: Topological full groups
Creators: name: Tanner, Owen
Publisher: name: University of Glasgow
Year: 2024

description: We develop our understanding of topological full groups, a way of constructing examples of infinite simple groups with finiteness properties from ample groupoids. Our results are concentrated in three main example classes. Firstly, the topological full groups of purely infinite minimal groupoids share many properties with Thompson’s group V. In studying these groups and the associated groupoids in detail, we formalise this phenomenon by relating dynamical properties to group-theoretic properties. Secondly, interval exchange groups are an important concrete example of topological full groups since many are amenable. We classify these groups through computing associated Elliot invariants. Also, we find concrete generating sets and compute the homology of these groups. Thirdly and finally, Stein’s groups were introduced by Melanie Stein in 1992 as generalisations of Thompson’s group. We show these groups are topological full groups. We then analyse Stein’s groups through this framework, showing that the (simple) derived subgroups of Stein’s groups are in many cases finitely generated. We study the homology of Stein’s groups.

Creators: name: ATLAS Collaboration
Publisher: name: HEPData
Year: 2017

description: Pseudocode illustrating the event and object selections for all the $1\ell 3b$ signal regions
description: A search for direct top squark pair production resulting in events with either a same-flavour opposite-sign dilepton pair with invariant mass compatible with a $Z$ boson or a pair of jets compatible with a Standard Model (SM) Higgs boson ($h$) is presented. Requirements on additional leptons, jets, jets identified as originating from b-quarks, and missing transverse momentum are imposed to target the other decay products of the top squark pair. The analysis is performed using proton-proton collision data at sqrt{s} = 13 TeV collected with the ATLAS detector at the LHC in 2015-2016, corresponding to an integrated luminosity of 36.1 fb$^{−1}$. No excess is observed in the data with respect to the expected SM predictions. The results are interpreted in two sets of models. In the first set, direct production of pairs of lighter top squarks ($\tilde{t}_1$) with long decay chains involving $Z$ or Higgs bosons is considered. The second set includes direct pair production of the heavier top squark pairs ($\tilde{t}_2$) decaying via $\tilde{t}_2 \rightarrow Z \tilde{t}_1$ or $\tilde{t}_2 \rightarrow h \tilde{t}_1$. The results exclude at 95% confidence level $\tilde{t}_2$ and $\tilde{t}_1$ masses up to about 800 GeV, extending the exclusion region of supersymmetric parameter space covered by previous LHC searches.
Exposing the threshold structure of loop integrals

description: The understanding of the physical laws determining the infrared behaviour of amplitudes is a longstanding and topical problem. In this paper, we show that energy conservation alone implies strong constraints on the threshold singularity structure of Feynman diagrams. In particular, we show that it implies a representation of loop integrals in terms of Fourier transforms of non-simplicial convex cones. We then engineer a triangulation that has a direct diagrammatic interpretation in terms of a straightforward edge-contraction operation. We use it to develop an algorithmic procedure that performs the Fourier integrations in closed form, yielding the novel Cross-Free Family three-dimensional representation of loop integrals. Contrary to the TOPT and LTD representations, its singularity structure is entirely and elegantly expressed in terms of the graph-theoretic notions of connectedness and crossing. These results can be used to classify infrared-finite scattering theories, numerically evaluate loop integrals and to simplify threshold regularisation procedures.

description: In this paper we construct rotating charged hairy black hole in (2+1) dimensions for infinitesimal black hole charge and rotation parameters. Then we consider this black hole as particle accelerator and calculate the center-of-mass energy of two colliding test particles near the rotating charged hairy black hole in (2+1) dimensions. As we expected, the center-of-mass energy has infinite value.
