description: The Pierre Auger Observatory (PAO) and Telescope Array (TA) collaborations report significant differences in the observed energy spectra of ultra-high-energy cosmic rays (UHECRs) above 30~EeV. In this work we present a joint fit of TA and PAO data using the rigidity-dependent maximum energy model, including a full marginalization over all relevant parameters. We test two possible scenarios to explain these differences. One is that they are due to complex energy-dependent experimental systematics; the other is the presence of a local astrophysical source in the Northern Hemisphere, which is only visible by the TA experiment. We show that the astrophysical and systematic scenarios improve the explanation of the data equally well, compared to the scenario where both experiments observe the same UHECR flux from a cosmological source distribution and have energy-independent systematics. We test different mass compositions emitted from the local source and conclude that the data are best described by a source lying at a distance below 26~Mpc that emits cosmic rays dominated by the silicon mass group. We also discuss possible source candidates, and the possible role of the putative local UHECR source in the observed TA anisotropy and in the differences in TA spectral data from different declination bands.

description: Können Informationssysteme dazu beitragen, die Reaktionsfähigkeit eines Unternehmens zu erhöhen? Wie müssen insbesondere Workflow-Management-Systeme technisch ge-staltet sein, wenn sie das Ziel der organisatorischen Flexibilität unterstützen sollen? Diese Fragen stehen im Mittelpunkt der Betrachtungen des vorliegenden Beitrags. Es werden Methoden vorgestellt, die der Anpassung von Workflow-Modellen dienen, und Vorge-hensweisen zur Aushandlung zwischen den Beteiligten eines Anpassungsprozesses dis-kutiert. Eine kontinuierliche Verbesserung der workflow-gestützten Geschäftsprozesse wird erst dann möglich, wenn zu den organisatorischen Konzepten geeignete Workflow-Management- Systeme hinzukommen, die die erforderliche Flexibilität bereitstellen. Die hierzu im Kooperationsverbund "Verbesserung von Geschäftsprozessen mit flexiblen Workflow-Management-Systemen (MOVE)" bisher erarbeiteten Lösungsvorschläge werden in dem Beitrag präsentiert.

description: To evaluate, in a pasture-based dairy herd, the response to a three-time point hoof trimming regime on lameness incidence and time from calving to observation of an elevated locomotion score (LS). This study was conducted on a 940-cow spring-calving herd in New Zealand’s North Island between May 2018 and May 2019. Cows (n = 250) were randomly allocated to the hoof trimming group, with the remainder assigned to the non-trim cohort. One trained professional hoof trimmer used the five-step Dutch method to trim the hind feet of the trimming group. Throughout the subsequent production season, the whole herd was locomotion-scored fortnightly using the 4-point (0–3) Dairy NZ lameness score. Kaplan–Meier survival curves were used to assess the univariable effect of trimming on the interval between calving and first LS of ≥ 2 and first LS ≥ 1. A multivariable Cox proportional hazards regression was used to further evaluate the effect of trimming on time to elevated LS. Mean lameness (LS ≥ 2) prevalence was 2.6%, with 30% of cows having ≥ 4 observations during the study period when at least one LS was ≥ 2. For LS ≥ 1, mean prevalence was 40%, with 98.6% of cows having ≥ 4 observations during the study period when at least one LS was ≥ 1 during lactation. Hoof trimming had no apparent effect on the incidence of clinical lameness (LS ≥ 2) (trimmed vs. non-trimmed: 33.2% vs. 28.8%, respectively), but for LS ≥ 1, there was a small decrease in the incidence of LS ≥ 1 (trimmed vs. non-trimmed: 96.9% vs. 99.3%, respectively). The hazard of a cow having a first observed LS ≥ 2 in the control group was 0.87 (95% CI = 0.66–1.14) times that of the trimmed group; however, the hazard of a cow having a first LS ≥ 1 was 1.60 (95% CI = 1.37–1.88) times higher in the control than in the trimmed group. On this farm, prophylactic hoof trimming had no clinically relevant impact on the incidence of clinical lameness and was not associated with clinically beneficial reductions in time to first observed LS ≥ 2. This may be because claw horn imbalance was not pronounced on this farm, with 53% of cows needing no trim on either hind limb on the first trimming occasion. Further research on the response to prophylactic trimming in pasture-based dairy cattle is required.

description: We propose a hybrid model governed by the Blume-Emery-Griffiths (BEG) Hamiltonian with a mean-field-like interaction, where the spins are randomly quenched such that some of them are "pure" Ising and the others admit the BEG set of states. It is found, by varying the concentration of the Ising spins, that the model displays different phase portraits in concentration-temperature parameter space, within the canonical and the microcanonical ensembles. Phenomenological indications that these portraits are rich and rather unusual are provided.

description: Novel physical phenomena arising at the interface of complex oxide heterostructures offer exciting opportunities for the development of future electronic devices. Using the prototypical LaAlO$_3$/SrTiO$_3$ interface as a model system, we employ a single-step lithographic process to realize gate tunable Josephson junctions through a combination of lateral confinement and local side gating. The action of the side gates is found to be comparable to that of a local back gate, constituting a robust and efficient way to control the properties of the interface at the nanoscale. We demonstrate that the side gates enable reliable tuning of both the normal-state resistance and the critical (Josephson) current of the constrictions. The conductance and Josephson current show mesoscopic fluctuations as a function of the applied side gate voltage, and the analysis of their amplitude enables the extraction of the phase coherence and thermal lengths. Finally, we realize a superconducting quantum interference device in which the critical currents of each of the constriction-type Josephson junctions can be controlled independently via the side gates.

description: In a collection of nearly 400 drawings entitled Livre de caricatures tant bonne que mauvaises, Charles-Germain de Saint-Aubin (1721-1786) ridiculed every aspect of French culture from King Louis XV and his court, to the poorest pockets of society. For the purposes of this thesis, I will be focusing on Saint-Aubin’s drawings of anonymous women, wives, and mistresses. Along with the depictions of women, I will examine the instances in which he draws men dressed up as women. Charles-Germain uses the image of women to highlight the follies of man. I cannot and will not argue these images are in any way kind towards women, but I will aim to illustrate the ways in which they are critical of men.

description: The cosmological constant presents one of the most fascinating and confounding problems in physics. A straightforward, seemingly robust prediction of quantum mechanics and general relativity is that the vacuum energy gravitates. Therefore, the cosmological constant should be enormous. It is minuscule. Since there is no understanding of why the cosmological constant is so small, it is important to test this idea in many different situations. In particular, given the span of distances in astronomy and particle physics, it is vital to test the gravitation of vacuum energy on as many distance scales as we can. Rydberg atoms open up a new set of distances for exploration. It is satisfying to measure the cosmological constant with an atom, but its main significance is extending measurements to microscopic distances. Here, too, there is no evidence of the gravitation of the vacuum. At scales of a micron and less, we place a limit of $7$ GeV on the scale of gravitating vacuum energy, well below the scale of $100$ GeV of the SM of particle physics.

description: This paper describes a new code optimization technique for digital signal processors (DSPs). One important characteristic of DSP algorithms are iterative accesses to data array elements within loops. DSPs support efficient address computations for such array accesses by means of dedicated address generation units (AGUs). We present a heuristic technique which, given an AGU with a fixed number of address registers, minimizes the number of instructions needed for array address computations in a program loop.

description: The prominent flat-spectrum radio quasar J0017+8135 (S5 0014+81) at z = 3.366 is one of the most luminous active galactic nuclei (AGN) known. Its milliarcsecond-scale radio jet structure has been studied with very long baseline interferometry (VLBI) since the 1980s. The quasar was selected as one of the original defining objects of the International Celestial Reference Frame, but left out from its current second realization (ICRF2) because of systematic long-term positional variations. Here we analyse archival 8.6- and 2.3-GHz VLBI imaging data collected at nearly 100 different epochs during more than 20 years, to obtain information about the kinematics of jet components. Because of the cosmological time dilation, extensive VLBI monitoring data are essential to reveal changes in the jet structure of high-redshift AGN. In the case of J0017+8135, the data can be described with a simple kinematic model of jet precession with a 12-year periodicity in the observer's frame.

Year: 2017

description: The purpose of this thesis is to examine the effect of perceived price fairness and customer satisfaction and loyalty on Ethiopian airlines customers. In this research, the dimensions of price fairness, customer satisfaction, and customer loyalty are extracted from marketing literature. The effect was examined via data obtained from customers of Ethiopian airlines using SPSS simple regression analysis. Statistical Society of this research is the customers of Ethiopian airlines and the number of samples is 384. Customers are selected judgment sampling for answering the questionnaire. Statistical Package for the Social Sciences (SPSS) modeling is applied in this research. According to the result of the study, perceived price fairness has a significant positive effect on customer satisfaction, similarly, the results showed that perceived price fairness has a significant positive on loyalty; therefore, perceived price fairness increases customer satisfaction and loyalty. Furthermore, the results of the study indicate that customer satisfaction positively influences customer loyalty lending support to customer satisfaction as a factor of predicting customers repeat purchase. Finally, decision-making implications are provided based on the study results, information with regards to the study limitations and suggestion for further research is presented in the thesis.
Strong coupling, weak impact: Phonon coupling versus pure dephasing in the photon statistics of cooperative emitters

description: Realising scalable quantum networks requires a meticulous level of understanding and mitigating the deleterious effects of decoherence. Many quantum device platforms feature multiple decoherence mechanisms, often with a dominant mechanism seemingly fully masking others. In this paper, we show how access to weaker dephasing mechanisms can nevertheless be obtained for optically active qubits by performing two-photon coincidence measurements. To this end we theoretically investigate the impact of different decoherence mechanisms on cooperatively emitting quantum dots. Focusing on the typically dominant deformation-potential coupling to longitudinal acoustic phonons and typically much less severe additional sources of pure dephasing, we employ a numerically exact method to show that these mechanisms lead to very different two-photon coincidence signals. Moreover, surprisingly, the impact of the strongly coupled phonon environment is weak and leads to long-lived coherences. We trace this back to the superohmic nature of the deformation-potential coupling causing inter-emitter coherences to converge to a nonzero value on a short timescale, whereas pure dephasing contributions cause a complete decay of coherence over longer times. Our approach provides a practical means of investigating decoherence processes on different timescales in solid state emitters, and thus contributes to understanding and possibly eliminating their detrimental influences.

description: Medical records from a single UK-based referral hospital were retrospectively reviewed to identify brachycephalic dogs who had undergone corrective airway surgery and were nebulised with adrenaline in the post-operative period. Ninety dogs were identified between August 2014 and March 2020. Agitation following nebulisation with adrenaline was uncommon, with 86/90 (96%) dogs remaining calm, and overall outcome was reported as satisfactory in 68 of 73 (89%) dogs for which this information was available. Median respiratory rate at T0 (prior to first nebulisation) and T60 (1 hour following nebulisation) were both 20 breaths/minute with a median difference of 0 (95% CI = 0–0) breaths/minute (p = 0.657). Median heart rate at T0 and T60 were both 80 beats/minute with a median difference of 3 (95% CI = −10 to 7) beats/minute (p = 0.948). Two dogs experienced tachycardia, but this was not associated with the timing of administration of adrenaline. Complications reported in the 24 hours following surgery included regurgitation (n = 36), increased respiratory noise and effort (n = 10), aspiration pneumonia (n = 4), and inappetence (n = 3). A temporary tracheostomy tube was placed in 13 (14.4%) dogs. Nebulisation with adrenaline is feasible, results in minimal increases in respiratory rate and heart rate and is associated with agitation in only a small number of dogs.

description: Optical bound states in the continuum (BIC) allow to totally prevent a photonic mode from radiating into free space along a given spatial direction. Polariton excitations derived from the strong radiation-matter interaction of a BIC with an excitonic resonance inherit an ultralong radiative lifetime and significant nonlinearities due to their hybrid nature. However, maximizing the light-matter interaction in these structures remains challenging, especially with 2D semiconductors, thus preventing the observation of room temperature nonlinearities of BIC polaritons. Here we show a strong light-matter interaction enhancement at room temperature by coupling monolayer WS2 excitons to a BIC, while optimizing for the electric field strength at the monolayer position through Bloch surface wave confinement. By acting on the grating geometry, the coupling with the active material is maximized in an open and flexible architecture, allowing to achieve a 100 meV photonic bandgap with the BIC in a local energy minimum and a record 70 meV Rabi splitting. Our novel architecture provides large room temperature optical nonlinearities, thus paving the way to tunable BIC-based polariton devices with topologically-protected robustness to fabrication imperfections.

description: Raman interactions in alkali vapours are used in applications such as atomic clocks, optical signal processing, generation of squeezed light and Raman quantum memories for temporal multiplexing. To achieve a strong interaction the alkali ensemble needs both a large optical depth and a high level of spin-polarisation. We implement a technique known as quenching using a molecular buffer gas which allows near-perfect spin-polarisation of over $99.5\%$ in caesium vapour at high optical depths of up to $\sim 2 \times 10^5$; a factor of 4 higher than can be achieved without quenching. We use this system to explore efficient light storage with high gain in a GHz bandwidth Raman memory.

In this work, we investigated the production mechanism of PBHs base on the first-order phase transition induced by quartic effective thermal potential of a scalar field in dark sector. We found the phase transition with vacuum energy, $\mathcal{O}(1)\lesssim B^{1/4}/{\rm MeV} \lesssim \mathcal{O}(100)$, produces the desired PBH mass and abundance fraction. Correlated signatures of gravitational wave and extragalactic gamma-ray from phase transition and black hole evaporation, respectively, are within $μ$Ares and AMEGO/e-ASTROGAM projected sensitivities.

description: We propose a model describing the evolution of the free electron current density in graphene. Based on the concept of Mp-branes, we perform the analysis using the difference between curvatures of parallel and antiparallel spins. In such a framework an effective graviton emerges in the form of gauge field exchange between electrons. In a plain graphene system, the curvatures produced by both kinds of spins neutralize each other. However, in the presence of defects, the inequality between curvatures leads to the emergence of current density, modified gravity and conductivity. Depending on the type of the defects, the resulting current density can be negative or positive.

description: The redshift factor $z$ is an invariant quantity of fundamental interest in post-Newtonian and self-force descriptions of compact binaries. It connects different approximation schemes, and plays a central role in the first law of binary black hole mechanics, which links local quantities to asymptotic measures of energy and angular momentum in these systems. Through this law, the redshift factor is conjectured to have a close relation to the surface gravity of the event horizons of black holes in circular orbits. We propose and implement a novel method for extracting the redshift factor on apparent horizons in numerical simulations of quasicircular binary inspirals. Our results confirm the conjectured relationship between $z$ and the surface gravity of the holes and that the first law holds to a remarkable degree for binary inspirals. The redshift factor enables tests of analytic predictions for $z$ in spacetimes where the binary is only approximately circular, giving a new connection between analytic approximations and numerical simulations.

description: Telecom industries, like other service providing industries should assess their service marketing strategy.. The aim of this study is to analyze the service marketing mix elements especially 7P's relationship as well as their impact on ethiotelecom fixed line sales performance. The research is descriptive in nature and survey questionnaire were used for the collection of data with personal face to face interview with branch manager, executives, officers and employees of the ethio telecom. The study questionnaire included 50 questions and the sample size was 104. Non probability judgment sampling technique was used to select the respondents. Descriptive statistics, ANOVA and multiple regressions were used to analyze the data. The results demonstrate that most of the variables have at least minimal relationship with ethio telecom fixed line sales performance. It is observed in the study that among the seven service marketing mix elements products and service, and price were found to have more positive relationship and effects on ethio telecom fixed line sales performance. The important finding help gather knowledge and understanding about the scenario of elements of service marketing mix and highlights elements that mostly influence the ethiotelecom fixed line product and service sales . The contribution made by the study is to make clear understanding about the concept of marketing mix tools that will help service marketing managers to properly construct and design customized fixed line telecom products and service with affordable price to satisfy their needs more effectively and efficiently through dynamic and innovative service marketing strategies

description: Medical records from a single UK-based referral hospital were retrospectively reviewed to identify brachycephalic dogs who had undergone corrective airway surgery and were nebulised with adrenaline in the post-operative period. Ninety dogs were identified between August 2014 and March 2020. Agitation following nebulisation with adrenaline was uncommon, with 86/90 (96%) dogs remaining calm, and overall outcome was reported as satisfactory in 68 (89%) dogs. Median respiratory rate at T0 (prior to first nebulisation) and T60 (1 hour following nebulisation) were both 20 breaths/minute with a median difference of 0 (95% CI = 0–0) breaths/minute (p = 0.657). Median heart rate at T0 and T60 were both 80 beats/minute with a median difference of 3 (95% CI = －10 to 7) beats/minute (p = 0.948). Two dogs experienced tachycardia, but this was not associated with the timing of administration of adrenaline. Complications reported in the 24 hours following surgery included regurgitation (n = 36), increased respiratory noise and effort (n = 10), aspiration pneumonia (n = 4), and inappetence (n = 3). A temporary tracheostomy tube was placed in 13 (14.4%) dogs. Nebulisation with adrenaline is feasible, results in minimal increases in respiratory rate and heart rate and is associated with agitation in only a small number of dogs.

description: Light field (LF) images containing information for multiple views have numerous applications, which can be severely affected by low-light imaging. Recent learning-based methods for low-light enhancement have some disadvantages, such as a lack of noise suppression, complex training process and poor performance in extremely low-light conditions. To tackle these deficiencies while fully utilizing the multi-view information, we propose an efficient Low-light Restoration Transformer (LRT) for LF images, with multiple heads to perform intermediate tasks within a single network, including denoising, luminance adjustment, refinement and detail enhancement, achieving progressive restoration from small scale to full scale. Moreover, we design an angular transformer block with an efficient view-token scheme to model the global angular dependencies, and a multi-scale spatial transformer block to encode the multi-scale local and global information within each view. To address the issue of insufficient training data, we formulate a synthesis pipeline by simulating the major noise sources with the estimated noise parameters of LF camera. Experimental results demonstrate that our method achieves the state-of-the-art performance on low-light LF restoration with high efficiency.

description: The emergence of cosmic structure is commonly considered one of the most complex phenomena in Nature. However, this complexity has never been defined nor measured in a quantitative and objective way. In this work we propose a method to measure the information content of cosmic structure and to quantify the complexity that emerges from it, based on Information Theory. The emergence of complex evolutionary patterns is studied with a statistical symbolic analysis of the datastream produced by state-of-the-art cosmological simulations of forming galaxy clusters. This powerful approach allows us to measure how many bits of information are necessary to predict the evolution of energy fields in a statistical way, and it offers a simple way to quantify when, where and how the cosmic gas behaves in complex ways. The most complex behaviors are found in the peripheral regions of galaxy clusters, where supersonic flows drive shocks and large energy fluctuations over a few tens of million years. Describing the evolution of magnetic energy requires at least a twice as large amount of bits than for the other energy fields. When radiative cooling and feedback from galaxy formation are considered, the cosmic gas is overall found to double its degree of complexity. In the future, Cosmic Information Theory can significantly increase our understanding of the emergence of cosmic structure as it represents an innovative framework to design and analyze complex simulations of the Universe in a simple, yet powerful way.

description: We discuss the Wormholes in general dimensions by studying the Einstein-phantom scalar field with and without the cosmological constant. Solving AdS wormholes in general dimension is hard due to the nonlinear nature of the theory. In this work, we implement the AdS/Ricci-flat correspondence, extended to include the axion field (the phantom scalar field), to construct AdS wormholes. Wormholes of Ellis-Bronnikov class are discussed in general dimensions.

Stabilization by Institutionalization: Electoral Competition and Authoritarian Regime Durability
Creators: name: Zand, Arian
Publisher: name: University of Chicago

description: Abstract: Authoritarian regimes adopt nominally democratic institutions despite the inherent uncertainty that these institutions entail. What effects do elections and parties have on authoritarian regime stability? Are autocracies with parties and competitive elections more stable than their less electorally competitive counterparts? What functions can elections serve in non-democracies? This paper provides a naïve Bayesian informational theory of electoral institutionalization under authoritarianism. Democratic emulation, exemplified in parties and elections, enhances the chance of authoritarian survival by supplying the ruling elites with (1) information about the sources of support and opposition to the regime among the citizenry and (2) information to monitor intra-party mobilization capacity, loyalty and performance. Autocrats update their beliefs about the probabilities of support and opposition after each election. Over time, this cumulative learning helps them maximize their survival chances. From this basic theory, three observable implications are derived and subsequently tested: (1) party-based authoritarian regimes are more stable than more closed authoritarian regimes, and (2) on average, the higher the degree of legislative and executive electoral competitiveness within a regime and across regimes, the higher the probability of regime survival would be, and (3) the stabilizing effect of electoral competitiveness grows over time. To test these predictions, I use three functional forms, respectively: (1) product-limit Kaplan-Meier with stringent log-rank specification, (2) a modified version of the Cox proportional hazard model, and (3) Aalen additive risk estimation. Despite the limitations of the models in drawing solid causal inference, the findings lend support to the stabilization by institutionalization hypothesis.
Tunneling-induced fractal transmission in Valley Hall waveguides

description: The Valley Hall effect provides a popular route to engineer robust waveguides for bosonic excitations such a photons and phonons. The almost complete absence of backscattering in many experiments has its theoretical underpinning in a smooth-envelope approximation that neglects large momentum transfer and is accurate only for small bulk band gaps and/or smooth domain walls. For larger bulk band gaps and hard domain walls backscattering is expected to become significant. Here, we show that in this experimentally relevant regime, the reflection of a wave at a sharp corner becomes highly sensitive on the orientation of the outgoing waveguide relative to the underlying lattice. Enhanced backscattering can be understood as being triggered by resonant tunneling transitions in quasimomentum space. Tracking the resonant tunneling energies as a function of the waveguide orientation reveals a self-repeating fractal pattern that is also imprinted in the density of states and the backscattering rate at a sharp corner.

description: The objectives of the present study were to understand the influence of sales skills dimensions which are: interpersonal skills, salesmanship skills, technical skills and marketing skills on sales performances of salespeople, in the case of Habesha Real Estate. This is an empirical study with quantitative research design and particularly, utilizing correlation research methodology. Data has been collected using self-report questionnaire and all sales agents within the organization were included as respondents (n = 62, 95% response rate). The data has been analyzed using SPSS software employing the descriptive statistics, Pearson's correlation and hierarchical regression statistical techniques. Bivariate correlation analysis between sales skills and sales performance of the sales people showed that all sales skills have statistically significant relationship with salespersons' performance at p = 0.01. A two-step hierarchical regression analysis indicated that marketing (β = 0.98, t = 3.27, p = 0.01), interpersonal (β = 0.73, t = 2.45, p = 0.05) and technical (β = -0.69, t = -2.41, p = 0.05) skills were statistically significant that contribute 77.7% (R2-change = 0.777, p = 0.01) to the predicting power of the model that enhance salesperson performance. In contrast, the findings also revealed that salesmanship skills do not influence salespersons' performance

description: We investigate dynamics of Gaussian states of continuous variable systems under Gaussianity preserving channels. We introduce a hierarchy of such evolutions encompassing Markovian, weakly and strongly non-Markovian processes, and provide simple criteria to distinguish between the classes, based on the degree of positivity of intermediate Gaussian maps. We classify all single-mode phase-insensitive Gaussian channels according to their non-Markovianity degree, and show that weak non-Markovianity has an operational significance as it leads to temporary amplification of Gaussian inputs beyond the fundamental quantum limit. Explicit examples and applications are discussed.

description: The case of Ukraine has exposed old problems that migrant and refugee women have long faced. Since there is ample evidence that international migration policies are not adapted to the needs of migrant women, today we have the opportunity to change this by demanding a gender-sensitive approach in the formulation of these policies. Such policies must also be inclusive, covering all migrant women regardless of their origin, legal status, skin color, religion, social class, or sexual orientation.

description: Two-dimensional materials support deeply confined and tunable plasmonic modes, which have great potential for achieving device miniaturization and flexible manipulation. In this paper, we propose a diffraction-unlimited system composed of borophene layer and perovskite grating to investigate the strong coupling between the borophene guiding plasmon (BGP) and perovskite exciton (PE) mode. The resonant energy of BGP mode could be electrically tuned to match the energy of PE mode, and a remarkable Rabi splitting is attained under zero-detuning condition. The splitting energy could reach 230 meV due to the strong field enhancement provided by BGP mode. Consequently, an active reflective phase modulation with 1.76π range is achieved by dynamically manipulating the detuning. Furthermore, by increasing the distance between the borophene layer and perovskite grating, a parity-time symmetry breaking could be observed with the vanished energy splitting. Our results deepen the understanding of light-matter interaction at the sub-wavelength scale and provide a guideline for designing active plasmonic devices.
