description: In this paper we consider systems of quantum particles in the $4d$ Euclidean space which enjoy conformal symmetry. The algebraic relations for conformal-invariant combinations of positions and momenta are used to construct a solution of the Yang-Baxter equation in the unitary irreducibile representations of the principal series $Δ=2+iν$ for any left/right spins $\ell,\dot{\ell}$ of the particles. Such relations are interpreted in the language of Feynman diagrams as integral \emph{star-triangle} identites between propagators of a conformal field theory. We prove the quantum integrability of a spin chain whose $k$-th site hosts a particle in the representation $(Δ_k,\ell_k, \dot{ \ell}_k)$ of the conformal group, realizing a spinning and inhomogeneous version of the quantum magnet used to describe the spectrum of the bi-scalar Fishnet theories. For the special choice of particles in the scalar $(1,0,0)$ and fermionic $(3/2,1,0)$ representation the transfer matrices of the model are Bethe-Salpeter kernels for the double-scaling limit of specific two-point correlators in the $γ$-deformed $\mathcal{N}=4$ and $\mathcal{N}=2$ supersymmetric theories.

description: In electrical engineering metamaterials have been developed that offer unprecedented control over electromagnetic fields. Here we show that general relativity lends the theoretical tools for designing devices made of such versatile materials. Given a desired device function, the theory describes the electromagnetic properties that turn this function into fact. We consider media that facilitate space-time transformations and include negative refraction. Our theory unifies the concepts operating behind the scenes of perfect invisibility devices, perfect lenses, the optical Aharonov-Bohm effect and electromagnetic analogs of the event horizon, and may lead to further applications.
An investigation of athlete satisfaction with the sport team selection process
Creators: name: Neu, Lois
Publisher: name: University of British Columbia
Year: 2009

description: Athletes frequently express concerns regarding the team selection process. Previously, few studies in the Sport Psychology literature have addressed variables associated with the team selection process, and specifically, there is no theoretical framework which identifies the relationship between athlete satisfaction and the team selection process. The current research investigates several variables (task type, team size, criteria, selection method, perceived control, self-esteem, motivation, performance, lifesatisfaction, age and gender of the athlete, and preferred decision-making style of the leader) which may influence athlete satisfaction with the team selection process. Investigating the team selection process might provide information for the improvement of current selection procedures, and such changes may result in a greater amount of athlete satisfaction with the sport team selection process, as well as, satisfaction with sport in general. Male and female athlete volunteers (208) who had experienced a British Columbia provincial team selection process within the last two years, completed the Causal Dimension Scale, Rotter’s Internal-External Locus of Control Scale, Rosenberg’s Self-Esteem Scale, the Sport Orientation Questionnaire, and a demographic questionnaire (The Personal Information Questionnaire). Automatic Interaction Detection (AID) analysis was used to analyze the data. The variables of performance outcome, motivation, perceived controI, self esteem, knowledge of criteria, decision making style, perception of performance, and age, influenced athlete satisfaction with the team selection process. Performance outcome accounted for 17.5% of the total variance found in an athlete’s satisfaction with the selection process. Athletes selected to the team were more satisfied than those who were not selected. Surprisingly, performance outcome affected male satisfaction more than female satisfaction, selection method affected female satisfaction but not male satisfaction, and locus of control affected male satisfaction but not female satisfaction. Furthermore, performance satisfaction influenced female satisfaction with the sport team selection process, but did not affect male satisfaction, and selfesteem affected male satisfaction more than female satisfaction. Results suggested that athlete satisfaction with selection processes might be enhanced if, sport organizations consider certain variables (performance, self-esteem, motivation, and perceived control) when developing team selection processes, and if athletes consider the same variables to develop psychological methods of coping with not being selected. Satisfying selection procedures may result in greater athlete commitment to sport and an improvement in performance through increased efforts.
Self-similarity in the breakup of very dilute viscoelastic solutions

description: When pushed out of a syringe, polymer solutions form droplets attached by long and slender cylindrical filaments whose diameter decreases exponentially with time before eventually breaking. In the last stages of this process, a striking feature is the self-similarity of the solution shape near the end of the filament. This means that shapes at different times, if properly rescaled, collapse onto one universal shape. A theoretical description inspired by this similarity observation and based on the Oldroyd-B model was recently shown to disagree with existing experimental results. By revisiting these measurements and analysing the interface profiles of very diluted polyethylene oxide solutions at high temporal and spatial resolution, we show that they are very well described by the model.

description: In this paper we consider smooth oriented hypersurfaces in 2-step nilpotent Lie groups with a left invariant metric and derive an expression for the Laplacian of the Gauss map for such hypersurfaces in the general case and in some particular cases. In the case of CMC-hypersurface in the (2m+1)-dimensional Heisenberg group we also derive necessary and sufficient conditions for the Gauss map to be harmonic and prove that for m=1 all CMC-surfaces with the harmonic Gauss map are "cylinders".
Phenomenological description of the two energy scales in underdoped superconducting cuprates

description: Raman and ARPES experiments have demonstrated that in superconducting underdoped cuprates nodal and antinodal regions are characterized by two energy scales instead of the one expected in BCS. The nodal scale decreases with underdoping while the antinodal one increases. Contrary to the behavior expected for an increasing energy scale, the antinodal Raman intensity decreases with decreasing doping. Using the Yang, Rice and Zhang (YRZ) model, we show that these features are a consequence of the non-conventional nature of the superconducting state in which superconductivity and pseudogap correlations are both present and compete for the phase space.

description: Presentación del Trabajo Fin de Máster del Máster Universitario TIC en Educación: Análisis y Diseño de Procesos, Recursos y Prácticas Formativas, defendido en el Curso 2018-2019 en la Facultad de Educación de la Universidad de Salamanca. Este trabajo ha sido tutorizado por el Dr. Francisco José García Peñalvo y la Dra. Alicia García Holgado en el contexto del Proyecto H2020 WYRED. La competencia digital es la elegida en este estudio ya que se considera de acuerdo con la Comisión Europea, como base esencial para el aprendizaje, dando paso la adquisición de otras competencias debido a su transversalidad educativa. Entre esas competencias se encuentra la de la comunicación en idiomas extranjeros, cuya adquisición es una de las razones principales para la implementación de la metodología CLIL (aprendizaje integrado de contenido y lengua extranjera). Este método se alía inesperadamente con el interés principal de este proyecto, permitiendo así el trabajo grupal y la necesidad de que los estudiantes se apropien de su propia contribución a la comunidad (plataforma colaborativa), en otras palabras, se observa como la serendipia, es decir, la posibilidad de hacer al azar descubrimientos inesperados y afortunados mientras se busca otra cosa, nos presenta un sin fin de oportunidades que ofrecen la integración entre las tecnologías de la información y la comunicación y el método CLIL. Es así como este proyecto, a través de un diseño de estudio de caso, pretende demostrar el impacto que provee la interacción en plataformas colaborativas, influyendo en el aumento de la motivación por el aprendizaje del idioma inglés en este caso de once participantes adolescentes pertenecientes a una academia de inglés. El análisis cualitativo de los datos indicó que la telecolaboración fomenta y contribuye no solo al desarrollo del aprendizaje del inglés sino también al aprendizaje de las mismas competencias y habilidades digitales.

description: A virtual flow meter (VFM) enables continuous prediction of flow rates in petroleum production systems. The predicted flow rates may aid the daily control and optimization of a petroleum asset. Gray-box modeling is an approach that combines mechanistic and data-driven modeling. The objective is to create a computationally feasible VFM for use in real-time applications, with high prediction accuracy and scientifically consistent behavior. This article investigates five different gray-box model types in an industrial case study using real, historical production data from 10 petroleum wells, spanning at most four years of production. The results are diverse with an oil flow rate prediction error in the range of 1.8%-40.6%. Further, the study casts light upon the nontrivial task of balancing learning from both physics and data. Consequently, providing general recommendations towards the suitability of different hybrid models is challenging. Nevertheless, the results are promising and indicate that gray-box VFMs may reduce the prediction error of a mechanistic VFM while remaining scientifically consistent. The findings motivate further experimentation with gray-box VFM models and suggest several future research directions to improve upon the performance and scientific consistency.

description: The aim of the present thesis was to study the cases that can be considered as just and equitable causes that could allow partners or stakeholders to file a request before court, asking for a dissolution order of partnerships, limited liability companies and limited companies prior to the agreed date. It is examined why just and equitable causes are regulated as grounds for dissolution of the above mentioned partnerships and companies and their legislative history till today. The thesis also presents similarities and differences that are identified in the just cause dissolution court order of the above mentioned partnerships and companies. Furthermore, an attempt is made to specify and classify the just and equitable causes, that can induce the dissolution court order of the above mentioned partnerships and companies, using examples of the national case-law. Another issue that is analysed is the court proceeding of the just cause dissolution of the above mentioned partnerships and companies

description: We perform lattice simulations of two-flavor QCD using Neuberger's overlap fermion, with which the exact chiral symmetry is realized at finite lattice spacings. The epsilon-regime is reached by decreasing the light quark mass down to 3 MeV on a 16^3 32 lattice with a lattice spacing \sim 0.11 fm. We find a good agreement of the low-lying Dirac eigenvalue spectrum with the analytical predictions of the chiral random matrix theory, which reduces to the chiral perturbation theory in the epsilon-regime. The chiral condensate is extracted as Σ(2 GeV) = (251(7)(11) MeV)^3, where the errors are statistical and an estimate of the higher order effects in the epsilon-expansion.

description: Religious education is a matter of particular theoretical and research interest, given the significant differences found in the ways in which it is developed and organized in the European context. At the same time, it is strongly concerned with the public and academic dialogue at a time when European societies are becoming multicultural and multi-religious. The aim of this study is to explore the framework governing religious education in Europe today, focusing on the respective models applied in different European countries and presenting nine case studies that fall under different approaches. According to the findings of the study, religious education in European countries follows either the confessional or the non-confessional approach, with the respective courses being either compulsory or voluntary. However, the gradual convergence observed in these different approaches of religious education in the European area reveals similarities even between these different models, while variations exist even within countries

description: This paper is related to our previous works [1][2] on the error estimate of the averaging technique, for systems with one fast angular variable. In the cited references, a general method (of mixed analytical and numerical type) has been introduced to obtain precise, fully quantitative estimates on the averaging error. Here, this procedure is applied to the motion of a satellite in a polar orbit around an oblate planet, retaining only the J_2 term in the multipole expansion of the gravitational potential. To exemplify the method, the averaging errors are estimated for the data corresponding to two Earth satellites; for a very large number of orbits, computation of our estimators is much less expensive than the direct numerical solution of the equations of motion.

Prediction of triathon performance from ventilatory threshold measurements

Year: 2008

description: The purpose of this study was to predict Ironman Triathlon (2.4 mile swim, 112 mile cycle, 26.2 mile run) performance times from ventilatory threshold (TVENT) measurements of swimming, cycling, and running. Ten trained triathletes (mean age = 29.7yrs., ht = 179.8cm, wt = 76.8kg, bodyfat = 11.4%) performed progressive intensity tests for treadmill running, cycle ergometry, and tethered swimming. The excess CO2 elimination curve was used to determine TVENT in each component sport with the resulting estimated times of 64.2, 380.0,174.5, 672.8 minutes for swimming, cycling, running, and overall time respectively. Individual estimates were then compared to actual segment and overall times to produce the following linear regression equations for predicting actual from estimated time (in minutes): actual swim = 1.15 * estimated swim - 6.75 actual cycle = 0.22 * estimated cycle + 262.6 actual run = 3.03 * estimated run - 267.1 actual overall = (-3.58 * est. swim) + (-0.10 * est. cycle) + (3.76 * est. run)+ 291.35 Significant correlations of r = 0.83, 0.70, 0.76, and 0.89 were calculated between swim, cycle, run, and overall estimated versus actual times respectively. Thus, between 49 and 69% of the variance in actual time is explained by TVENT for that component sport. Also, 78% of the total variability was accounted for by the TvENT estimation when the three sports were combined. These findings suggest that while TvENT is able to account for a significant proportion of triathlon performance time other factors such as fatigue, dehydration, terrain, heat, etc.are confounding the overall prediction.

description: We describe a simple method for measuring the residual fast phase noise of a cavity-stabilized laser using the cavity as a reference. The method is based on generating a beat note between the laser output and the strongly filtered light transmitted through the cavity. The beat note can be directly analyzed without requiring further calibration of system parameters. We apply the method to measure the residual phase noise of an external-cavity diode laser (ECDL) locked to a reference cavity and compare the results with an analysis of the in-loop error signal of the feedback system.

description: We study the power of several scalar quantities constructed on the sphere (presented in Monteserin et al. 2005) to detect non-Gaussianity on the temperature distribution of the cosmic microwave background (CMB). The test has been performed using non-Gaussian CMB simulations with injected skewness or kurtosis generated through the Edgeworth expansion. We have also taken into account in the analysis the effect of anisotropic noise and the presence of a Galactic mask. We find that the best scalars to detect an excess of skewness in the simulations are the derivative of the gradient, the fractional isotropy, the Laplacian and the shape index. For the kurtosis case, the fractional anisotropy, the Laplacian and the determinant are the quantities that perform better.

description: The annihilation of light dark matter was recently advocated as a possible explanation of the large positron injection rate at the Galactic center deduced from observations by the SPI spectrometer aboard INTEGRAL. The modelling of internal Bremsstrahlung and in-flight annihilation radiations associated to this process drastically reduced the mass range of this light dark matter particle. We estimate critically the various energy losses and radiations involved in the propagation of the positron before its annihilation --in- flight or at rest. Using a simple model with mono-energetic positrons injected and confined to the Galactic bulge, we compute energy losses and gamma-ray radiations caused by ionization, Bremsstrahlung interactions as well as in-flight and at rest annihilation and compare these predictions to the available observations, for various injection energies. Confronting the predictions with observations by the CGRO/EGRET, CGRO/COMPTEL, INTEGRAL/SPI and INTEGRAL/IBIS/ISGRI instruments, we deduce a mass upper bound of 3 to 7.5 MeV/c^2 for the hypothetical light dark matter particle. The most restrictive limit is in agreement with the value previously found by Beacom and Yuksel and was obtained under similar assumptions, while the 7.5 MeV/c^2 value corresponds to more conservative choices and to a partially ionized propagation medium. We stress how the limit depends on the degree of ionization of the propagation medium and how its precision could be improved by a better appraisal of data uncertainties.

description: Published high-resolution rotation-vibration transitions of \spec{h212c16o}, the principal isotopologue of methanal, are analyzed using the MARVEL (Measured Active Rotation-Vibration Energy Levels) procedure. The literature results are augmented by new, high-accuracy measurements of pure rotational transitions within the ground, $ν_3$, $ν_4$, and $ν_6$ vibrational states. Of the \nbNonRedTr\ non-redundant transitions processed, which come from \nbSr\ sources including the present work, \nbValTr\ could be validated, providing \nbEl\ empirical energy levels of \spec{h212c16o}\ with statistically well-defined uncertainties. All the empirical rotational-vibrational energy levels determined are used to improve the accuracy of ExoMol's AYTY line list for hot formaldehyde. The complete list of collated experimental transitions, the empirical energy levels determined, as well as the extended and improved line list are provided as Supplementary Material.

description: Similar to the optimal-doped, weak-ferromagnetic (WFM induced by canted antiferromagnetism, T$_{Curie}$ = 131 K) and superconducting (T$_{c}$ = 56 K) RuSr$_{2}$GdCu$_{2}$O$_{8}$, the underdoped RuSr$_{2}$EuCu$_{2}$O$_{8}$ (T$_{Curie}$ = 133 K, T$_{c}$ = 36 K) also exhibited a spontaneous vortex state (SVS) between 16 K and 36 K. The low field ($\pm$20 G) superconducting hysteresis loop indicates a weak and narrow Meissner state region of average lower critical field B$_{c1}^{ave}$(T) = B$_{c1}^{ave}$(0)[1 - (T/T$_{SVS}$)$^{2}$], with B$_{c1}^{ave}$(0) = 7 G and T$_{SVS}$ = 16 K. The vortex melting transition (T$_{melting}$ = 21 K) below T$_{c}$ obtained from the broad resistivity drop and the onset of diamagnetic signal indicates a vortex liquid region due to the coexistence and interplay between superconductivity and WFM order. No visible jump in specific heat was observed near T$_{c}$ for Eu- and Gd-compound. This is not surprising, since the electronic specific heat is easily overshadowed by the large phonon and weak-ferromagnetic contributions. Furthermore, a broad resistivity transition due to low vortex melting temperature would also lead to a correspondingly reduced height of any specific heat jump. Finally, with the baseline from the nonmagnetic Eu-compound, specific heat data analysis confirms the magnetic entropy associated with antiferromagnetic ordering of Gd$^{3+}$ (J = S = 7/2) at 2.5 K to be close to $\it{N_{A}k}$ ln8 as expected.

description: Attempts at constraining theories of late time accelerated expansion often assume broad priors for the parameters in their phenomenological description. Focusing on shift-symmetric scalar-tensor theories with standard gravitational wave speed, we show how a more careful analysis of their dynamical evolution leads to much narrower priors. In doing so, we propose a simple and accurate parametrisation of these theories, capturing the redshift dependence of the equation of state, $w(z)$, and the kinetic braiding parameter, $α_{\rm B}(z)$, with only two parameters each, and derive their statistical distribution (a.k.a. theoretical priors) that fit the cosmology of the underlying model. We have considered two versions of the shift-symmetric model, one where the energy density of dark energy is given solely by the scalar field, and another where it also has a contribution from the cosmological constant. By including current data, we show how theoretical priors can be used to improve constraints by up to an order of magnitude. Moreover, we show that shift-symmetric theories without a cosmological constant are observationally viable. We work up to quartic order in first derivatives of the scalar in the action and our results suggest this truncation is a good approximation to more general shift-symmetric theories. This work establishes an actionable link between phenomenological parameterisations and Lagrangian-based theories, the two main approaches to test cosmological gravity and cosmic acceleration.

Multispectral analysis of solar EUV images:linking temperature to morphology

Year: 2007

description: Solar images taken simultaneously at different wavelengths in the EUV are widely used for understanding structures such as flares, coronal holes, loops, etc. The line-of-sight integration and the finite spectral resolution of EUV telescopes, however, hinders interpretation of these individual images in terms of temperature bands. Traditional approaches involve simple visualisation or explicit modelling. We take a more empirical approach, using statistical methods. The morphology of solar structures changes with the wavelength of observation and, therefore, with temperature. We explore the possibility of separating the different solar structures from a linear combination of images. Using a blind source separation approach, we build a new set of statistically independent "source" images from the original EUV images. Two techniques are compared: the singular value decomposition and independent component analysis. The source images show more contrast than the original ones, thereby easing the characterisation of morphological structures. A comparison with the differential emission measure shows that each source image also isolates structures with specific emission temperatures.

Low-lying Dirac eigenmodes and monopoles in 3+1D compact QED

Year: 2008
Subjects: subject: High Energy Physics - Lattice (hep-lat)

description: We study the properties of low-lying Dirac modes in quenched compact QED at $β=1.01$, employing $12^3\times N_t$ ($N_t =4,6,8,10,12$) lattices and the overlap formalism for the fermion action. We pay attention to the spatial distributions of low-lying Dirac modes below and above the ``phase transition temperature'' $T_c$. Near-zero modes are found to have universal anti-correlations with monopole currents, and are found to lose their temporal structures above $T_c$ exhibiting stronger spatial localization properties. We also study the nearest-neighbor level spacing distribution of Dirac eigenvalues and find a Wigner-Poisson transition.

description: Our aim is to bring the theory of analogous polytopes to bear on the study of quasitoric manifolds, in the context of stably complex manifolds with compatible torus action. By way of application, we give an explicit construction of a quasitoric representative for every complex cobordism class as the quotient of a free torus action on a real quadratic complete intersection. We suggest a systematic description for omnioriented quasitoric manifolds in terms of combinatorial data, and explain the relationship with non-singular projective toric varieties (otherwise known as toric manifolds). By expressing the first and third authors' approach to the representability of cobordism classes in these terms, we simplify and correct two of their original proofs concerning quotient polytopes; the first relates to framed embeddings in the positive cone, and the second involves modifying the operation of connected sum to take account of orientations. Analogous polytopes provide an informative setting for several of the details.

description: Σκοπός της παρούσας διπλωματικής εργασίας είναι η προσέγγιση και ερμηνεία του άρθρου 177 παρ. 2 του ΚΠΔ, όπως αυτό έχει διαμορφωθεί μετά την τροποποίησή του από το άρθρο 10 παρ. 2 του ν. 3674/2008. Η ερμηνεία της διάταξης στηρίχθηκε σε μία σύντομη νομοθετική και νομολογιακή ιστορική αναδρομή, στην αιτιολογική έκθεση του ν. 3674/2008 και στις περιρρέουσες αυτήν κοινωνικοπολιτικές συγκυρίες -που οδήγησαν ουσιαστικά στην ψήφιση της εν λόγω διάταξης- καθώς και στην παράλληλη με το άρθρο 177 παρ. 2 ΚΠΔ αναφορά και προσέγγιση του άρθρου 19 παρ. 3 του Συντάγματος. Η παρούσα καταλήγει στο συμπέρασμα ότι υπάρχει ανάγκη συνταγματικής και νομοθετικής μεταρρύθμισης τόσο του άρθρου 19 παρ. 3 του Συντάγματος όσο και του άρθρου 177 παρ. 2 ΚΠΔ, καθώς, ούτως ή άλλως, η ελληνική θεωρία και νομολογία δεν αποδέχονται τον άκαμπτο και αυστηρό χαρακτήρα της απαγόρευσης του άρθρου 177 παρ. 2 ΚΠΔ, εφαρμόζοντας διάφορες «σταθμιστικές» κυρίως θεωρίες περί χρήσης των παράνομων αποδεικτικών μέσων σε εξαιρετικές περιπτώσεις. Τούτη δε η ερμηνευτική προσέγγιση εξακολουθεί ακόμη και σήμερα, με κάποιες διαφοροποιήσεις λόγω των υφιστάμενων νομοθετικών μεταρρυθμίσεων, με αποτέλεσμα η παρούσα θεματική να εξακολουθεί να είναι επίκαιρη.
description: The aim of the present thesis is the approach and understanding of the article 177 par. 2 of the Greek Criminal Procedure Code (CPC), as it has been modified by the article 10 παρ. 2 of the law 3674/2008. The interpretation of this article was based on a brief legislative and judicial historic review, on the explanatory memorandum of the law 3674/2008 and the surrounding socio-political circumstances –that practically led to the above legislation- as well as on the parallel to the article 177 par. 2 of the CPC reference and approach of the article 19 par. 3 of the Greek Constitution. The present thesis reaches the conclusion that a constitutional and legislative reform of the articles 177 par. 2 of the CPC and 19 par. 3 of the Greek Constitution is required, since in any case, the Greek Academics and Jurisprudence do not accept the “stiff and rigorous” implementation of the article 177 par. 2 of the CPC, applying instead in exceptional cases several intermediate theories regarding the use of the illicit means of evidence. This approach is followed even today, despite the subsequent amendments. As a result, the present theme is still up to date.
Time-varying properties of asymmetric volatility and multifractality in Bitcoin

Subjects: subject: Statistical Finance (q-fin.ST)

description: This study investigates the volatility of daily Bitcoin returns and multifractal properties of the Bitcoin market by employing the rolling window method and examines relationships between the volatility asymmetry and market efficiency. Whilst we find an inverted asymmetry in the volatility of Bitcoin, its magnitude changes over time, and recently, it has become small. This asymmetric pattern of volatility also exists in higher frequency returns. Other measurements, such as kurtosis, skewness, average, serial correlation, and multifractal degree, also change over time. Thus, we argue that properties of the Bitcoin market are mostly time dependent. We examine efficiency-related measures: the Hurst exponent, multifractal degree, and kurtosis. We find that when these measures represent that the market is more efficient, the volatility asymmetry weakens. For the recent Bitcoin market, both efficiency-related measures and the volatility asymmetry prove that the market becomes more efficient.

description: With updated experimental data and improved theoretical calculations, several significant deviations are being observed between the Standard Model predictions and the experimental measurements of the branching ratios of $\bar{B}_{(s)}^0\to D_{(s)}^{(*)+} L^-$ decays, where $L$ is a light meson from the set $\{π,ρ,K^{(\ast)}\}$. Especially for the two channels $\bar{B}^0\to D^{+}K^-$ and $\bar{B}_{s}^0\to D_{s}^{+}π^-$, both of which are free of the weak annihilation contribution, the deviations observed can even reach 4-5$σ$. Here we exploit possible new-physics effects in these class-I non-leptonic $B$-meson decays within the framework of QCD factorization. Firstly, we perform a model-independent analysis of the effects from twenty linearly independent four-quark operators that can contribute, either directly or through operator mixing, to the quark-level $b\to c\bar{u} d(s)$ transitions. It is found that, under the combined constraints from the current experimental data, the deviations observed could be well explained at the $1σ$ level by the new-physics four-quark operators with $γ^μ(1-γ_5)\otimesγ_μ (1-γ_5)$ structure, and also at the $2σ$ level by the operators with $(1+γ_5)\otimes(1-γ_5)$ and $(1+γ_5)\otimes(1+γ_5)$ structures. However, the new-physics four-quark operators with other Dirac structures fail to provide a consistent interpretation, even at the $2σ$ level. Then, as two specific examples of model-dependent considerations, we discuss the case where the new-physics four-quark operators are generated by either a colorless charged gauge boson or a colorless charged scalar, with their masses fixed both at the $1$~TeV. Constraints on the effective coefficients describing the couplings of these mediators to the relevant quarks are obtained by fitting to the current experimental data.
