description: The search for new physics signals in Higgs precision measurements plays a pivotal role in the High-Luminosity Large Hadron Collider (HL-LHC) and future colliders programs. The Higgs properties are expected to be measured with great experimental precision, implying higher-order perturbative computations of the electroweak parameters from the theoretical side. In particular, the renormalized Higgs boson mass parameter in the Standard Model shows significant variation around the electroweak scale, resulting in a lower-bound theoretical uncertainty that exceeds future collider expectations. A more stable result under the renormalization group can be computed from a non-zero external momentum Higgs self-energy, for which available calculations include 3-loop corrections in the QCD sector. In this work, we present an additional contribution by estimating the leading non-QCD 3-loop corrections to the mass of the Higgs boson in the top-Yukawa sector of order $y_t^6$. The momentum-dependent Higgs self-energy is computed in the tadpole-free scheme for the Higgs vacuum expectation value in the Landau gauge, and the explicit dependence upon the Higgs boson and top quark masses is shown. The obtained result is expressed in dimensional regularization as a superposition of a set of master integrals with coefficients that are free of poles in four space-time dimensions, and the corrections are evaluated numerically by the sector decomposition method.

NLO electroweak corrections to off-shell top-antitop production with leptonic decays at the LHC

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

description: For the first time the next-to-leading-order electroweak corrections to the full off-shell production of two top quarks that decay leptonically are presented. This calculation includes all off-shell, non-resonant, and interference effects for the 6-particle phase space. While the electroweak corrections are below one per cent for the integrated cross section, they reach up to 15% in the high-transverse-momentum region of distributions. To support the results of the complete one-loop calculation, we have in addition evaluated the electroweak corrections in two different pole approximations, one requiring two on-shell top quarks and one featuring two on-shell W bosons. While the former deviates by up to 10% from the full calculation for certain distributions, the latter provides a very good description for most observables. The increased centre-of-mass energy of the LHC makes the inclusion of electroweak corrections extremely relevant as they are particularly large in the Sudakov regime where new physics is expected to be probed.

Evidence for an accreting massive black hole in He 2-10 from adaptive optics integral field spectroscopy

description: Henize 2-10 is a blue dwarf galaxy with intense star formation and one the most intriguing question about it is whether or not it hosts an accretingmassive black hole. We use H and K-band integral field spectra of the inner 130 pc$\times$130 pc of He 2-10 to investigate the emission and kinematics of the gas at unprecedented spatial resolution. The observations were done using the Gemini Near-Infrared Integral Field Spectrograph (NIFS) operating with the ALTAIR adaptive optics module and the resulting spatial resolutions are 6.5 pc and 8.6 pc in the K and H bands, respectively. Most of the line emission is due to excitation of the gas by photo-ionization and shocks produced by the star forming regions. In addition, our data provide evidence of emission of gas excited by an active galactic nucleus located at the position of the radio and X-ray sources, as revealed by the analysis of the emission-line ratios. The emission lines from the ionized gas in the field present two kinematic components: one narrow with a velocity field suggesting a disk rotation and a broad component due to winds from the star forming regions. The molecular gas shows only the narrow component. The stellar velocity dispersion map presents an enhancement of about 7 km s$^{-1}$ at the position of the black hole, consistent with a mass of $1.5^{+1.3}_{-1.3}\times10^6$ M$_\odot$.

Scaling and Kinetic Exchange Like Behavior of Hirsch Index and Total Citation Distributions: Scopus-CiteScore Data Analysis

description: We analyze the data distributions $f(h)$, $f(N_c$) and $f(N_p)$ of the Hirsch index $(h)$, total citations ($N_c$) and total number of papers ($N_p$) of the top scoring 120,000 authors (scientists) from the Stanford cite-score (or c-score) 2022 list and their corresponding $h$ ($3 \le h \le 284$), $N_c (1009 \le N_c \le 428620$) and $N_p$ ($3\le N_p \le 3791$) statistics from the Scopus data. For reasons explained in the text, we divided the data of these top scorers (c-scores in the range 5.6125 to 3.3461) into six successive equal-sized Groups of 20,000 authors or scientists. We tried to fit, in each Group, $f(h)$, $f(Nc)$ and $f(Np)$ with Gamma distributions, viewing them as the ``wealth distributions'' in the fixed saving-propensity kinetic exchange models and found $f(h) \sim h^{γ_h} \mathrm{exp} (-h/T_h)$ with fitting noise level or temperature level ($T_h$) and average value of $h$, and the power $γ_h$ determined by the ``citation saving propensity'' in each Group. We further showed that using some earlier proposed power law scaling like $h = D_c N_c^{α_c}$ (or $h = D_p N_p^{α_p}$) with $α_c = 1/2 = α_p$, we can derive the observed $f(h)$ from the observed $f(N_c)$ or $f(N_p)$, with $D_c = 0.5$, but $D_p$ depending on the Group considered. This observation suggests that the average citations per paper ($N_c/N_p$) in each group ($= (D_p/D_c)^2 =4D_p^2$) vary (from 58 to 29) with the c-score range of the six Groups considered here, implying different effective Dunbar-like coordination numbers of the scientists belonging to different groups or networks.

description: Our recently developed conventional, explicitly correlated, and local natural orbital (LNO) based coupled cluster with single, double, and perturbative triple excitations [CCSD(T)] methods are utilised to closely approach the basis set limit of interaction energies between medium-sized molecular complexes. The study is partly motivated by our previous finding that state-of-the-art diffusion Monte Carlo and CCSD(T) interaction energies are not in complete agreement even for some of the dimers in the popular S66 compilation [Al-Hamdani and Nagy et al. Nat. Commun. (2021) 12:3927]. We improve upon the previous S66 CCSD(T) reference by using up to the quadruple-ζ (QZ) level CCSD(T) contributions, utilising our recent (T+) approach and suggesting a more robust explicitly correlated CCSD reference. Our efficient LNO-CCSD(T) method allowed us to also compute tightly converged, quintuple-ζ level interaction energies for the S66 set. Moreover, the new CCSD(T)/QZ references enabled the so far most rigorous benchmark of the LNO and other popular local correlation approaches on the S66 set. The accuracy of local approximations was found in the few 10 to few 100 cal/mol interaction energy error range, assuming sufficiently tight settings, such as the Tight and the Normal settings of LNO-CCSD(T) threshold combinations, respectively.

description: Noise remains the major obstacle to scalable quantum computation. Quantum benchmarking provides key information on noise properties and is an important step for developing more advanced quantum processors. However, current benchmarking methods are either limited to a specific subset of quantum gates or cannot directly describe the performance of the individual target gate. To overcome these limitations, we propose channel spectrum benchmarking (CSB), a method to infer the noise properties of the target gate, including process fidelity, stochastic fidelity, and some unitary parameters, from the eigenvalues of its noisy channel. Our CSB method is insensitive to state-preparation and measurement errors, and importantly, can benchmark universal gates and is scalable to many-qubit systems. Unlike standard randomized schemes, CSB can provide direct noise information for both target native gates and circuit fragments, allowing benchmarking and calibration of global entangling gates and frequently used modules in quantum algorithms like Trotterized Hamiltonian evolution operator in quantum simulation.

description: We consider a non-linear vertex-reinforced jump process (VRJP($w$)) on $\mathbb{Z}$ with an increasing measurable weight function $w:[1,\infty)\to [1,\infty)$ and initial weights equal to one. Our main goal is to study the asymptotic behaviour of VRJP($w$) depending on the integrability of the reciprocal of $w$. In particular, we prove that if $\int_1^{\infty} \frac{\text{d}u}{w(u)} =\infty$ then the process is recurrent, i.e. it visits each vertex infinitely often and all local times are unbounded. On the other hand, if $\int_1^{\infty} \frac{\text{d} u}{w(u)} <\infty$ and there exists a $ρ>0$ such that $t \mapsto w(t)^ρ\int_t^{\infty}\frac{\text{d}u}{w(u)}$ is non-increasing then the process will eventually get stuck on exactly three vertices, and there is only one vertex with unbounded local time. We also show that if the initial weights are all the same, VRJP on $\mathbb{Z}$ cannot be transient, i.e. there exists at least one vertex that is visited infinitely often. Our results extend the ones previously obtained by Davis and Volkov [Probab. Theory Relat. Fields (2002)] who showed that VRJP with linear reinforcement on $\mathbb{Z}$ is recurrent.

description: Hebb's idea of a cell assembly as the fundamental unit of neural information processing has dominated neuroscience like no other theoretical concept within the past 60 years. A range of different physiological phenomena, from precisely synchronized spiking to broadly simultaneous rate increases, has been subsumed under this term. Yet progress in this area is hampered by the lack of statistical tools that would enable to extract assemblies with arbitrary constellations of time lags, and at multiple temporal scales, partly due to the severe computational burden. Here we present such a unifying methodological and conceptual framework which detects assembly structure at many different time scales, levels of precision, and with arbitrary internal organization. Applying this methodology to multiple single unit recordings from various cortical areas, we find that there is no universal cortical coding scheme, but that assembly structure and precision significantly depends on brain area recorded and ongoing task demands.
Opportunities and Challenges of Large Scale Private Gold Mine Investments in Ethiopia: Tri-partite Interest and Contest
Creators: name: Metassebia, Hailu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: In spite of long history in the mining operations, Ethiopia"s economy has never enjoyed from the sector in a satisfactory way. Till now, the economy is highly dependable on agriculture even though the mining sector has got policy attention. Although the government"s vision concerning its contribution is to escalate up to one-tenth of the Gross Domestic Product (GDP), the industry"s position in the economy is still low and remains close to 1% of the GDP. Generally speaking, only three companies witnessed in large scale gold mining production investment for the last two and half decades under the free market economic policy. It is with these backgrounds, that the mining policy framework of the country must be examined and the challenges and opportunities of large scale private gold mine investments must be identified. The research mainly deals with challenges and prospects of large-scale private gold mine investments in Ethiopia. The study focuses mainly on large scale mining investment engagements and their challenges as well as opportunities. It does not include artisanal mining and state-owned operations since the focus of the research is large-scale gold mining investments. It is private investment that is the center of the discussion in the thesis. Accordingly, the paper attempts to identify the opportunities and challenges of large-scale private gold mine investments in Ethiopia by discovering the existence of the tripartite arrangement between the private sector, the government and the community. Finally, it identifies potential policy implementation gaps and possible remedy options in relation with large-scale private gold mine investments in Ethiopia. Research interview, focus group discussion (FGD) and observation were applied as primary data collection techniques. Document review was also used as a secondary data collection mechanism. Finally, the paper comes to conclusion that there is no institutional tripartite policy framework of stakeholders that addresses the problem of the large scale gold mining. All stakeholders need permanent forum of the tripartite relation that has to be mandated with addressing the challenges and expanding the opportunities obtained so far. A need for permanent forum (institution based) which can bring concerns of stakeholders on a discussion table is important in an effort to address comprehensive interests of all stakeholders.

description: We study the effects of three-nucleon short-range correlations on nuclear coordinate-space densities. For this purpose, novel three-body densities are calculated for ground state nuclei using the auxiliary-field diffusion Monte Carlo method. The results are analyzed in terms of the Generalized Contact Formalism, extended to include three-body correlations, revealing the universal behavior of nucleon triplets at short distances. We identify the quantum numbers of such correlated triplets and extract scaling factors of triplet abundances that can be compared to upcoming inclusive electron scattering data.

description: We present results from the 2D anisotropic Baryon Acoustic Oscillation (BAO) signal present in the final dataset from the WiggleZ Dark Energy Survey. We analyse the WiggleZ data in two ways: firstly using the full shape of the 2D correlation function and secondly focussing only on the position of the BAO peak in the reconstructed data set. When fitting for the full shape of the 2D correlation function we use a multipole expansion to compare with theory. When we use the reconstructed data we marginalise over the shape and just measure the position of the BAO peak, analysing the data in wedges separating the signal along the line of sight from that parallel to the line of sight. We verify our method with mock data and find the results to be free of bias or systematic offsets. We also redo the pre-reconstruction angle averaged (1D) WiggleZ BAO analysis with an improved covariance and present an updated result. The final results are presented in the form of $Ω_c h^2$, $H(z)$, and $D_A(z)$ for three redshift bins with effective redshifts $z = 0.44$, $0.60$, and $0.73$. Within these bins and methodologies, we recover constraints between 5% and 22% error. Our cosmological constraints are consistent with Flat $Λ$CDM cosmology and agree with results from the Baryon Oscillation Spectroscopic Survey (BOSS).

description: We introduce an algorithm to decide isomorphism between tensors. The algorithm uses the Lie algebra of derivations of a tensor to compress the space in which the search takes place to a so-called densor space. To make the method practicable we give a polynomial-time algorithm to solve a generalization of module isomorphism for a common class of Lie modules. As a consequence, we show that isomorphism testing is in polynomial time for tensors whose derivation algebras are classical Lie algebras and whose densor spaces are 1-dimensional. The method has been implemented in the Magma computer algebra system.

description: In this work, we study the shadow boundary curves of rotating time-dependent black hole solutions which have well-defined Kerr and Vaidya limits. These solutions are constructed by applying the Newman-Janis algorithm to a spherically symmetric seed metric conformal to the Vaidya solution with a mass function that is linear in Eddington-Finkelstein coordinates. Equipped with a conformal Killing vector field, this class of solution exhibits separability of null geodesics, thus allowing one to develop an analytic formula for the boundary curve of its shadow. We find a simple power law describing the dependence of the mean radius and asymmetry factor of the shadow on the accretion rate. Applicability of our model to recent Event Horizon Telescope observations of M87${}^*$ and Sgr A${}^*$ is also discussed.

The Effect Of Customer Relationship Marketing On Customer Loyalty: The Case Of Ries Engineering-Rental(Resco-Rental)
Creators: name: Dibekulu, Girma
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The main purpose of this study was to examine the effect of relationship marketing dimensions (trust, commitment, empathy and conflict handling) on customer loyalty in Ries Engineering-Rental. The study used a quantitative approach, and an explanatory research design was also employed. By considering the scope of the study all 60 B2B customers of Resco-Rental located in Addis Ababa were considered to take part in the study. A census study was conducted by taking 300 people including production managers, project managers, and general managers as a target respondent: 300 is the total available number of respondents in those, 60 B2B customers of Resco-rental. The study employed a questionnaire adopted from previous studies and relevant literature as a data gathering instrument. The researcher has gathered data from 270 respondents, which are about 90 % of the total 300 questioners that were distributed to respondents. The data analysis was conducted through statistical techniques such as descriptive statistics, bivariate correlations and multiple linear regressions by using SPSS software-version 20.00. The results of data analysis show that, the four variables namely, commitment, empathy. conflict handling and trust aggregately explained or affected 43.7% of variance on customer loyalty in descending order but the rest 56.3% is explained by other factors. Moreover, they are significantly related and contribute differentially to customer loyalty. Commitment is the most important predictor of customer loyalty followed by empathy, conflict handling and trust. This shows that, the company has to be committed enough to have customer loyalty and also need to focus it on its core services so as to gain its customers' trust. It is reasonable to conclude, on this evidence, that customer loyalty can be created, reinforced and retained by marketing plans aimed at building trust, demonstrating commitment to service, treating customers as they want to be treated, and handling conflicts effectively and efficiently. This study may be affected by a limitation because it couldn't involve other companies in the rental industry; however, the model allows the study to be a base for future researches

description: The decay behavior of the specific intensity is studied for the spatial-frequency domain imaging (SFDI). It is shown using the radiative transport equation that the decay is given by a superposition of different decay modes, and the decay rates of these modes are determined by spatial frequencies and Case's eigenvalues. This explains why SFDI can focus on shallow regions. The fact that light with nonzero spatial frequency rapidly decays makes it possible to exclusively extract optical properties of the top layer of a layered medium. We determine optical properties of the top layer of a solid phantom. This measurement is verified with different layered media of numerical phantoms.

description: In this paper we propose an algorithm for path following control of the nonholonomic mobile robot based on the idea of the guiding vector field (GVF). The desired path may be an arbitrary smooth curve in its implicit form, that is, a level set of a predefined smooth function. Using this function and the robot's kinematic model, we design a GVF, whose integral curves converge to the trajectory. A nonlinear motion controller is then proposed which steers the robot along such an integral curve, bringing it to the desired path. We establish global convergence conditions for our algorithm and demonstrate its applicability and performance by experiments with real wheeled robots.

description: On large cosmological scales, anisotropic gravitational collapse is manifest in the dark cosmic web. Its statistical properties are little known for alternative dark matter models such as fuzzy dark matter (FDM). In this work, we assess for the first time the relative importance of cosmic nodes, filaments, walls and voids in a cosmology with primordial small-scale suppression of power. We post-process $N$-body simulations of FDM-like cosmologies with varying axion mass $m$ at redshifts $z\sim 1.0-5.6$ using the NEXUS+ Multiscale Morphology Filter technique at smoothing scale $Δx = 0.04 \ h^{-1}$Mpc. The formation of wall and void halos is more suppressed than naively expected from the half-mode mass $M_{1/2}$. Also, we quantify the mass and volume filling fraction of cosmic environments and find that 2D cosmic sheets host a larger share of the matter content of the Universe as $m$ is reduced, with an $\sim 8-12$\% increase for the $m=7 \times 10^{-22}$ eV model compared to CDM. We show that in FDM-like cosmologies, filaments, walls and voids are cleaner and more pronounced structures than in CDM, revealed by a strong mid-range peak in the conditioned overdensity PDFs $P(δ)$. At high redshift, low-density regions are more suppressed than high-density regions. Furthermore, skewness estimates $S_3$ of the total overdensity PDF in FDM-like cosmologies are consistently higher than in CDM, especially at high redshift $z\sim 5.6$ where the $m=10^{-22}$ eV model differs from CDM by $\sim 6 σ$. Accordingly, we advocate for the usage of $P(δ)$ as a testbed for constraining FDM and other alternative dark matter models.

Genuinely noncyclic geometric gates in two-pulse schemes

Publisher: name: arXiv
Year: 2023

subject: FOS: Physical sciences

description: While most approaches to geometric quantum computation is based on geometric phase in cyclic evolution, noncyclic geometric gates have been proposed to increase further the flexibility. While these gates remove the dynamical phase of the computational basis, they do not in general remove it from the eigenstates of the time evolution operator, which makes the geometric nature of the gates ambiguous. Here, we resolve this ambiguity by proposing a scheme for genuinely noncyclic geometric gates. These gates are obtained by evolving the computational basis along open paths consisting geodesic segments, and simultaneously assuring that no dynamical phase is acquired by the eigenstates of the time evolution operator. While we illustrate the scheme for the simplest nontrivial case of two geodesic segments starting at each computational basis state of a single qubit, the scheme can be straightforwardly extended to more elaborate paths, more qubits, or even qudits.

description: We calculate the emission spectra, the Glauber $g^{(2)}$ function, and the entanglement of formation for a few two-level emitters coupled to a single cavity mode and subject to an external laser-excitation. To evaluate these quantities we couple the system to environmental degrees of freedom which leads to dissipative dynamics. Because of the periodic time-dependence of the system Hamiltonian, the coefficients of the (Markovian) master equation are constant if Floquet states are used as the computational basis. Studying the emission spectra we show that the dynamic Stark effect, i.e., the shift of spectral lines, first appears in the second order of the laser intensity. For the Glauber function, we find clearly distinguished parameter regimes of super- and sub-Poissonian light emission and explain the additional features appearing for finite laser intensity in terms of the quasienergy spectrum of the driven emitter-cavity system. Finally, we analyze the temperature and emitter-cavity coupling regimes where entanglement among the emitters is generated, and show that the laser-excitation leads to a decrease of entanglement.

description: A comment on the paper by S. M. Mahajan and F. A. Asenjo "Interacting quantum and classical waves: Resonant and non-resonant energy transfer to electrons immersed in an intense electromagnetic wave" [Phys. Plasmas 29, 022107 (2022)] where the authors use a model based on the Klein-Gordon equation to discuss particle energization by a transverse electromagnetic wave in a plasma. It is shown that the results of the paper are easily obtained in a classical approach, so that no quantum effect has to be invoked. Moreover, some mistakes and misinterpretations in the paper have been corrected. The (un)suitability of the proposed mechanism to account for generation of extremely energetic particles in both laboratory and astrophysical scenarios is also discussed.

Year: 2018

description: The purpose of this study was to examine factors that affect customers satisfaction on e-marketing services of the hotel industry. The study focused on five dimensions namely; Customization, Privacy, Global Accessibility of web pages, convenience and security which affect the e-satisfaction of the hotel customers. The study used mixed research approach to have a better insight and gain a richer understanding about the effect of e-marketing on customer satisfaction in the hotel industry from both the customers and the hotels point of view and the researcher has employed descriptive explanatory design to objectively answer the research questions. Both probability and non-probability sampling were used in the sampling technique. Purposive and convenience sampling, which are of non-probability sampling, were used to select the hotels and respondents among the e-marketing customers of the hotels respectively. Simple random sampling, which is of probability sampling, was used to select the hotels among the four star hotels. For achieving the study objective, 384 sample respondents were selected and data were collected in 5 point Likert scale questionnaire with closer assistance of the researcher. Additionally, the researcher has also used unstructured interview with the respective employees of the hotels to get assertive observations so that to get benefits of a mixed methods approach and to mitigate the bias in adopting only either quantitative or qualitative approach. The data, then, analyzed through descriptive and inferential statistics using linear regression. By the findings, out of the proposed five factors in affecting e-satisfaction of customers, the four factors namely; Customization, Privacy, Convenience and Security have found to be significant factors of e-satisfaction in the hotel industry and the remaining variable Global Accessibility of web pages was found to be statistically insignificant. Furthermore, on the basis of the research findings, appropriate recommendations along with implications for further studies have been forwarded

description: Evaporating droplets and films are used in applications from different fields. Various methods of evaporative self-assembly are of particular interest. The paper describes a mathematical model of mass transfer in a droplet drying on a substrate based on the lubrication approximation. The model takes into account the transfer of a dissolved or suspended substance by a capillary flow, the diffusion of this substance, the evaporation of liquid, the formation of solid deposit, the dependence of the viscosity and the vapor flux density on the admixture concentration. The case with pinning of the three-phase boundary is considered here. Explicit and implicit finite-difference schemes have been developed for the model equations. A modification of the numerical method is proposed, in which splitting by physical processes, the iterative method of explicit relaxation and Thomas algorithm are combined. A practical recipe for suppressing sawtooth oscillations is described using the example of a specific problem. A software module in C++ has been developed, which can be used for evaporative lithography problems in the future. With the help of this module, numerical calculations were carried out, the results of which were compared with the results obtained in the Maple package. Numerical simulation predicted the case in which the direction of the capillary flow changes to the opposite over time due to a change in the sign of the gradient of the vapor flux density. This can lead to a slowdown in the transfer of the substance to the periphery, which as a result will contribute to the formation of a more or less uniform precipitation over the entire contact area of the droplet with the substrate. This observation is useful for improving methods of annular deposit suppression associated with the coffee-ring effect and undesirable for some applications, such as inkjet printing or coating.

description: We construct a surface with a cylindrical end which has a finite number of Laplace eigenvalues embedded in its continuous spectrum. The surface is obtained by attaching a cylindrical end to a hyperbolic torus with a hole. To our knowledge, this is the first example of a manifold with a cylindrical end whose number of eigenvalues is known to be finite and nonzero. The construction can be varied to give examples with arbitrary genus and with an arbitrarily large finite number of eigenvalues. The constructed surfaces also have resonance-free regions near the continuous spectrum and long-time asymptotic expansions of solutions to the wave equation.

Year: 2019

description: The general objective of the study was to assess customer satisfaction and challenges in electronic banking system, the case of Oromia International Bank. Based on the objectives the study tried to address the basic questions of what are the products of e-banking service offered by OIB, what is the level of customer satisfaction at OIB, what problem do customer face in using e-banking service. The sampling method that used in the study was incidental sampling techniques. By using the incidental sampling techniques 100 respondents were participated to respond the questions. Descriptive method was used for analyzing data obtained from questionnaire and data gathered from interview. The general finding of the study showed that 70% customers were highly satisfied on e-banking products. The findings further suggested that customer negative perception about service delivery of the bank has significantly changed given the introduction of electronic banking products. It's been recommended that management of Oromia International Bank invest massively in IT in order to further promote efficient and smooth service delivery. There is also the need to extensively develop more E-banking products and to do extensive customer education to enable more customers patronize.

Author as Character and Narrator: Deconstructing Personal Narratives from the r/AmITheAsshole Reddit Community

description: In the r/AmITheAsshole subreddit, people anonymously share first person narratives that contain some moral dilemma or conflict and ask the community to judge who is at fault (i.e., who is "the asshole"). In general, first person narratives are a unique storytelling domain where the author is the narrator (the person telling the story) but can also be a character (the person living the story) and, thus, the author has two distinct voices presented in the story. In this study, we identify linguistic and narrative features associated with the author as the character or as a narrator. We use these features to answer the following questions: (1) what makes an asshole character and (2) what makes an asshole narrator? We extract both Author-as-Character features (e.g., demographics, narrative event chain, and emotional arc) and Author-as-Narrator features (i.e., the style and emotion of the story as a whole) in order to identify which aspects of the narrative are correlated with the final moral judgment. Our work shows that "assholes" as Characters frame themselves as lacking agency with a more positive personal arc, while "assholes" as Narrators will tell emotional and opinionated stories.

description: We consider a fermionic Hubbard chain with an additional next-to-nearest neighbor hopping term. We study the thermalization rates of the quasi-momentum distribution function within a quantum Boltzmann equation approach. We find that the thermalization rates are proportional to the square of the next-to-nearest neighbor hopping: Even weak next-to-nearest neighbor hopping in addition to nearest neighbor hopping leads to thermalization in a two-particle scattering quantum Boltzmann equation in one dimension. We also investigate the temperature dependence of the thermalization rates, which away from half filling become exponentially small for small temperature of the final thermalized distribution.
