description: The Self Consistent Random Phase Approximation (SCRPA) and a Direct Analytical (DA) method are proposed to solve the Extended Hubbard Model in 1D. We have considered an Extended Hubbard Model (EHM) including on-site and off-site interactions for closed chains in one dimension with periodic boundary conditions. The comparison of the SCRPA results with ones obtained by a Direct Analytical approach shows that the SCRPA treats the problem of these closed chains with a rigorous manner. The analysis of the nearest-neighbour repulsion effect on the dynamics of our closed chains shows that this repulsive interaction between the electrons of the neighbouring atoms induces supplementary conductivity, since, the SCRPA energy gap vanishes when these closed chains are governed by a strong repulsive on-site interaction and intermediate nearest-neighbour repulsion.

Towards Corporate Shared Value in Retail Sector: A Comparative Study over Grocery and Banking Between Italy and the UK
Creators: name: Candelo, Elena
name: Casalegno, Cecilia
name: Civera, Chiara
Publisher: name: International Journal of Economic Behavior
Year: 2015

description: The research investigates the extent to which Banking and Grocery retailers use Corporate Social Responsibility (CSR) in accordance to evolving consumers’ expectations and build a strategic model of Corporate Shared Value (CSV) to strive for economic and social returns simultaneously. The paper adopts a qualitative approach, based on the comparative case study methodology by investigating a sample of twelve Banking and Grocery retailers in Italy and the UK. Differences and similarities in CSR as new strategic model among countries and retail sectors emerge, with UK companies from both the sectors showing the most formalized integration of CSR within their business strategy. The chance for both Italian and UK retail companies is to adopt the best practices emerging from the case studies to turn their CSR programs into a strategic business model of CSV that will allow a stronger retailer-consumer relationship based on social improvements and a reinforcement of their brand image.

description: Results are presented for a semi-coherent search for continuous gravitational waves from the millisecond pulsar PSR J0437$-$4715, using a hidden Markov model to track spin wandering, in LIGO data from the third LIGO-Virgo observing run. This is the first search for PSR J0437$-$4715 to cover a wide frequency range from $60$ Hz to $500$ Hz and simultanously accommodate random spin deviations from the secular radio ephemeris. Two searches are performed with plausible coherence times of $10$ days and $30$ days, as the frequency wandering time-scale of the gravitational-wave-emitting quadrupole is unknown. The former analysis yields no surviving candidates, while the latter yields five candidates after the veto procedure. The detection statistic of each of the five survivors is mapped as a function of sky position, in preparation for follow-up analyses in the future, e.g. during LIGO-Virgo-KAGRA fourth observing run.

Propagation of spinors on a noncommutative spacetime: equivalence of the formal and the effective approach

description: Some noncommutative (NC) theories posses a certain type of dualities that are implicitly built within their structure. In this paper we establish still another example of this kind. More precisely, we show that the noncommutative U(1) gauge theory coupled to a NC scalar field and to a classical geometry of the Reissner Nordstrom (RN) type is completely equivalent at the level of equations of motion to the commutative U(1) gauge theory coupled to a commutative scalar field and to a classical geometry background, different from the starting RN background. The new (effective) metric is obtained from the RN metric by switching on an additional nonvanishing r-phi component. Using this duality between two theories and physical systems they describe, we formulate an effective approach to studying a dynamics of spin 1/2 fields on the curved background of RN type with an abiding noncommutative structure. As opposed to that, we also study the dynamics of spin 1/2 fields in a more formal way, by studying the semiclassical theory which describes the NC U(1) gauge field coupled with NC spin 1/2 field and also with gravity which is however treated classically. Upon utilising the Seiberg Witten map in order to write the NC spinor and NC gauge fields in terms of their corresponding commutative degrees of freedom, we find that the equation of motion for the fermion field obtained within the formal approach exactly coincides with the equation of motion obtained within the effective approach that utilises noncommutative duality. We then use these results to analyze the problem of stability of solutions of the equations of motion and the associated issue of superradiance, as related to fermions in RN spacetime with an allpervasive noncommutative structure.

Publisher: name: International Journal of Economic Behavior
Year: 2015

description: In recent years, the Balanced Scorecard has emerged as a popular performance measurement and management system used by many organizations globally. This system helps link the strategy and vision of a company to its day-to-day operations. To recognize those companies that have successfully implemented the Balanced Scorecard, the Palladium Group, a leading organization of strategic management, established a widely-respected global program: Balanced Scorecard Hall of Fame for Executing Strategy. Since 2000, 152 companies have been inducted into the Hall of Fame. An event study was conducted to test the impact on firm value from the announcement of induction into the Balanced Scorecard Hall of Fame. If the balanced scorecard properly aligns the business strategy with the short-term operations, these benefits should impact positively on the firm’s value. The results suggest some market price effect five- and ten-days prior to, but none following the announcement. The study’s findings and opportunities for further research are discussed.

description: A linear equation L is called k-regular if every k-coloring of the positive integers contains a monochromatic solution to L. Richard Rado conjectured that for every positive integer k, there exists a linear equation that is (k-1)-regular but not k-regular. We prove this conjecture by showing that the equation $\sum_{i=1}^{k-1} \frac{2^i}{2^i-1} x_i = (-1 + \sum_{i=1}^{k-1} \frac{2^i}{2^i-1}) x_0$ has this property. This conjecture is part of problem E14 in Richard K. Guy's book "Unsolved problems in number theory", where it is attributed to Rado's 1933 thesis, "Studien zur Kombinatorik".

Galactic rotation dynamics in a new $f(\mathcal{R})$ gravity model

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We propose to test the viability of the recently introduced $f(\mathcal{R})$ gravity model in the galactic scales. For this purpose we consider test particles moving in stable circular orbits around the galactic center. We study the Palatini approach of $f(\mathcal{R})$ gravity via Weyl transformation, which is the frame transformation from the Jordan frame to the Einstein frame. We derive the expression of rotational velocities of test particles in the new $f(\mathcal{R})$ gravity model. For the observational data of samples of high surface brightness and low surface brightness galaxies, we show that the predicted rotation curves are well fitted with observations, thus implying that this model can explain flat rotation curves of galaxies. We also study an ultra diffuse galaxy, AGC $242019$ which has been claimed in literature to be a dark matter dominated galaxy similar to low surface brightness galaxies with a slowly rising rotation curve. The rotation curve of this galaxy also fits well with the model prediction in our study. Furthermore, we studied the Tully-Fisher relation for the entire sample of galaxies and found that the model prediction shows the consistency with the data.

description: In this talk, we report our present work on the chiral magnetic effect (CME) under a strong magnetic field at low temperature. To this end, we use the instanton vacuum with the finite instanton-number fluctuation Delta, which relates to the nontrivial topological charge Q_t. We compute the vacuum expectation values of the local chiral density , chiral charge density and induced electromagnetic current . We observed that the longitudinal EM current is much larger than the transverse one, |j_perp/j_parallel| ~ Q_t, and the equals to the ||. It also turns out that the CME becomes insensitive to the magnetic field as T increases, since the instanton effect decreases.

Is Equality Fair?
Creators: name: Tarasov, Arthur
Publisher: name: International Journal of Economic Behavior
Year: 2015

description: This paper attempts to answer the question whether people consider decisions that lead to equal outcomes fair. I find that this is not always the case. In an experiment where subjects are given equal opportunities to choose how to divide money between each other in a two-player game, any strategy is perceived to be fair more than half the time, including the profit-maximizing strategy. The equal divisions that lead to equal outcomes are sometimes considered unfair by both players. Moreover, players frequently punished the others, whose decisions led to equal outcomes. I hypothesize that such punishments occur because people have different conceptions of what a fair outcome and fair punishment are.

description: We report new radial velocities of the TrES-4 transiting planetary system, including observations of a full transit, with the High Dispersion Spectrograph of the Subaru 8.2m telescope. Modeling of the Rossiter-McLaughlin effect indicates that TrES-4b has closely aligned orbital and stellar spin axes, with $λ= 6.3^{\circ} \pm 4.7^{\circ}$. The close spin-orbit alignment angle of TrES-4b seems to argue against a migration history involving planet-planet scattering or Kozai cycles, although there are two nearby faint stars that could be binary companion candidates. Comparison of our out-of-transit data from 4 different runs suggest that the star exhibits radial velocity variability of $\sim$20 ms^-1 in excess of a single Keplerian orbit. Although the cause of the excess radial velocity variability is unknown, we discuss various possibilities including systematic measurement errors, starspots or other intrinsic motions, and additional companions besides the transiting planet.

Exploring Higgs-Photon Production at the LHC

Year: 2022
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We have investigated the signal for physics beyond the Standard Model via Higgs plus photon final state, hitherto unobserved at the LHC, in the framework of Standard Model Effective Field Theory. Using the relevant dimension-6 operators, we probe two distinct classes of interactions, based on the Lorentz structure of Higgs couplings to gauge bosons and fermions. To begin with, constraints on the Wilson coefficients of these operators have been derived from existing experimental data. We then focus on the hadronic decay of the Higgs boson to two bottom quarks in the boosted regime, leading to a high $p_T$ fat-jet recoiling against a hard photon. Following a CMS Run II search for a resonance decaying into a Higgs boson and a photon, a detailed signal and background analysis for this channel has been done and limits on the relevant Wilson coefficients have been obtained. By performing a cut-based analysis, we identify some kinematic observables that distinguish between signal and SM background. Minimum values of the Wilson coefficients that will yield $3σ$ signal significance at the 14 TeV run of the LHC with $3000 ~\rm fb^{-1}$ data, have been obtained. A multivariate analysis using a boosted decision tree and exploiting the jet substructure techniques further help to isolate the regions of phase space where the contribution of SMEFT driven signal is significantly enhanced. Finally, we briefly discuss the parameter dependencies and interpretations of the allowed values of the coefficients on a particularly interesting UV complete model namely, Minimal Supersymmetric Standard Model.

description: The universal two-parameter ${\mathcal W}_{\infty}$-algebra is a classifying object for vertex algebras of type ${\mathcal W}(2,3,\dots, N)$ for some $N$. Gaiotto and Rapčák recently introduced a large family of such vertex algebras called $Y$-algebras, which includes many known examples such as the principal ${\mathcal W}$-algebras of type $A$. These algebras admit an action of $\mathbb{Z}_2$, and in this paper we study the structure of their orbifolds. Aside from the extremal cases of either the Virasoro algebra or the ${\mathcal W}_3$-algebra, we show that these orbifolds are generated by a single field in conformal weight $4$, and we give strong finite generating sets.

description: A longstanding problem in galactic simulations is to resolve the dynamical friction (DF) force acting on massive black hole particles when their masses are comparable to or less than the background simulation particles. Many sub-grid models based on the traditional Chandrasekhar DF formula have been proposed, yet they suffer from fundamental ambiguities in the definition of some terms in Chandrasekhar's formula when applied to real galaxies, as well as difficulty in evaluating continuous quantities from (spatially) discrete simulation data. In this work we present a new sub-grid dynamical friction estimator based on the discrete nature of $N$-body simulations, which also avoids the ambiguously-defined quantities in Chandrasekhar's formula. We test our estimator in the GIZMO code and find that it agrees well with high-resolution simulations where DF is fully captured, with negligible additional computational cost. We also compare it with a Chandrasekhar estimator and discuss its applications in real galactic simulations.

Methodological concerns about 'concordance-statistic for benefit' as a measure of discrimination in treatment benefit prediction

description: Prediction algorithms that quantify the expected benefit of a given treatment conditional on patient characteristics can critically inform medical decisions. Quantifying the performance of treatment benefit prediction algorithms is an active area of research. A recently proposed metric, the concordance statistic for benefit (cfb), evaluates the discriminative ability of a treatment benefit predictor by directly extending the concept of the concordance statistic from a risk model with a binary outcome to a model for treatment benefit. In this work, we scrutinize $cfb$ on multiple fronts. Through numerical examples and theoretical developments, we show that cfb is not a proper scoring rule. We also show that it is sensitive to the unestimable correlation between counterfactual outcomes and to the definition of matched pairs. We argue that measures of statistical dispersion applied to predicted benefits do not suffer from these issues and can be an alternative metric for the discriminatory performance of treatment benefit predictors.

description: NREL's computational sciences center hosts the largest high-performance computing (HPC) capabilities dedicated to energy research while functioning as a living laboratory for energy-efficient computing. NREL's HPC capabilities support the research needs of the Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE). In ten years of operation, HPC use in EERE-sponsored research has grown by a factor of 30, including work in electricity generation, energy efficiency, transportation, and energy system modeling. This paper analyzes this research portfolio, providing examples of individual use cases. The paper documents NREL's history of operating one of the world's most energy-efficient data centers while examining pathways to reduce economic and environmental impact beyond reduction of Power Usage Efficiency (PUE). This paper concludes by examining the unique opportunities created for accelerating improvements in data center efficiency created by combining an HPC system dedicated to energy research and a research program in energy-efficient computing.

We explore the interactions between rough-surfaced nanocolloids at the air--water interface through the compaction of monolayers experimentally and numerically. Sufficiently rough systems exhibit a non-trivial intermediate state between a gas-like state and a close-packed jamming state due to roughness-induced capillary attraction. We also find that roughness-induced friction lowers the jamming point, and the tangential contact force owing to surface asperities can cause a gradual off-plane collapse of the compressed monolayer.

The Role of Information Diffusion on Farmers Good Agricultural Practices: A Social Network Point of View – The Case of the French Agro-Environmental Practices
Creators: name: Cherni, Maryem
Publisher: name: International Journal of Economic Behavior
Year: 2016

description: Many recent researches focus on the sustainable agriculture and the advantage of the adoption of good agriculture practices for farmers, consumers and for the environment. In this work, we agree on one thing: better information diffusion leads to better adoption of good agricultural practices by farmers. The objective of our article is double. Firstly, we aim to propose an analytical model of the relevant factors which can help to better understanding the process of adoption of these practices. Our framework is developed around three main elements: the individual level (the information seeker), the economic level and the social network level. Secondly, we aim to test empirically this model, by confronting it to some field experience in agro-environmental practices. Our first empirical results put a lot of emphasis on the importance of the formal network in knowledge transfer. Finally, we discuss the implication for theory and practice and present the next steps of this ongoing research.

description: The DQC1 complexity class, or power of one qubit model, is examined as an open quantum system. We study the dynamics of a register of qubits carrying out a DQC1 algorithm and show that, for any algorithm in the complexity class, the evolution of the logical qubit can be described as an open quantum system undergoing a dynamics which is unital. Unital quantum channels respect the Tasaki-Crooks fluctuation theorem and we demonstrate how this is captured by the thermodynamics of the logical qubit. As an application, we investigate the equilibrium and non-equilibrium thermodynamics of the DQC1 trace estimation algorithm. We show that different computational inputs, i.e. different traces being estimated, lead to different energetic exchanges across the register of qubits and that the temperature of the logical qubit impacts the magnitude of fluctuations experienced and quality of the algorithm.

description: In machine learning, training data often capture the behaviour of multiple subgroups of some underlying human population. This behaviour can often be modelled as observations of an unknown dynamical system with an unobserved state. When the training data for the subgroups are not controlled carefully, however, under-representation bias arises. To counter under-representation bias, we introduce two natural notions of fairness in time-series forecasting problems: subgroup fairness and instantaneous fairness. These notions extend predictive parity to the learning of dynamical systems. We also show globally convergent methods for the fairness-constrained learning problems using hierarchies of convexifications of non-commutative polynomial optimisation problems. We also show that by exploiting sparsity in the convexifications, we can reduce the run time of our methods considerably. Our empirical results on a biased data set motivated by insurance applications and the well-known COMPAS data set demonstrate the efficacy of our methods.

description: Ca1-xSrxVO3 is a Mott-Hubbard-type correlated electron system whose bandwidth can be varied by the V-O-V bond angle, but the actual effect of bandwidth control on the electronic structure has been controversial in previous photoemission experiments. In this work, band dispersions and Fermi surfaces of SrVO3 and CaVO3 are studied by angle-resolved photoemission spectroscopy. Near the Fermi level (EF), three bands forming cylindricalFermi surfaces derived from the three V 3d t2g orbitals have been observed. The observed band widths for both compounds are almost half of those predicted by local-density-approximation band-structure calculation, confirming mass renormalization caused by electron correlation. It has been clearly demonstrated that the width of the d band in CaVO3 is narrower than that in SrVO3, qualitatively consistent with the result of band-structure calculation. Roles of the orthorhombic lattice distortion and electron correlation in the observed band narrowing are discussed.

description: I report on the discovery of the orbital periods of three recurrent novae in our galaxy. V745 Sco has an orbital period of 510+-20 days with ellipsoidal modulations, based on SMARTS photometry from 2004-2008. V3890 Sgr has an orbital period of 519.7+-0.3 days with ellipsoidal modulations and a shallow eclipse, based primarily on SMARTS and AAVSO photometry from 1995-2008, but also extending back to 1899 with archival plates. In addition, a sinusoidal modulation of amplitude 0.2 mag and period 103.8+-0.4 days is seen mainly in the red, with this attributed to ordinary pulsations in the giant companion star. V394 CrA has an orbital period equal to twice its primary photometric period (P_orb=1.515682+-0.000008 days), as based on photometry extending from 1989-2008. I use all available information (including the UBVRIJHK spectral energy distributions) to get distances to the four RNe with red giant companions as 800+-140 pc for T CrB, 4300+-700 pc for RS Oph, 7300+-1200 pc for V745 Sco, and 6000+-1000 pc for V3890 Sgr. Further, the red giant in the RS Oph system has a mass loss rate of close to 3.7x10^-8 M_sun/yr as based on many confident measures, and this is too weak (by a factor of 100,000) to supply the white dwarf with mass at the known rate of 3.9x10^-6 M_sun/yr. Thus, the only way to get matter onto the white dwarf fast enough is through Roche lobe overflow, and this confidently demonstrates that the distance to RS Oph is >~3000 pc.

description: Following the digital revolution, the traditional divide between value creation - R&D, production and advertising - and value distribution and consumption – sales, use and post-use- is blurring. Individuals and companies are called to exchange multiple inputs and outputs before, during and after sale. The new contemporarity of value processes is gradually leading to a new convergence among parties. Companies are enabled to promote, intermediate and intercept the customers conversation; individuals are committed to the new social game and keeping companies under non-contractual observation. This study researches the effects of e-WOM (Electronic-Word of Mouth) of individuals through a netnography on 20 worldwide crowd-sourcing platforms. Findings demonstrate that the new overlapping of dialogue and sale can generate a positive loop between companies and individuals responsibility and reduce the distance between market and society. Classification-JEL: Keywords: Co-advertising; E-WOM; Co-value chain; Social responsibility; Company-consumer communication; Consumer behavior; Netnography.

Prevalence of ‘Face Concept’ among South Asian Consumers. A Comparative Study of Unfolding the Facets in Decision Making Process of Buying Beauty Products
Creators: name: Pervin, Shahina
Publisher: name: International Journal of Economic Behavior
Year: 2016

description: The focus of this paper is to explore the level of importance of the term ‘face concept’, consumers transfer in their purchase decision of beauty products. The author intends to study differences in the consumption behaviour of highly collectivists Bangladeshi consumers’ compare to the highly individualistic UK consumers. Concept of face is acknowledged in every culture. However, the term ‘face’ is characterised differently according to one’s cultural setting; for example, ‘face’ represents the interpersonal relationship between the individual and groups in Asian society. On the other hand, from a European perspective face may represent stronger personal self and assertion. In this paper the author tends to identify the contributing factors to ‘face concept’ of Bangladeshi female consumers in their pre, actual and post-purchase behaviour of cosmetics products compared to the British female consumers. A structured questionnaire survey was conducted among female Bengali consumers in the capital city of Dhaka in Bangladesh and female British consumers in Southwest London in the United Kingdom. The research has compared the degree of face concept and its impact on decision making process of female consumers in the UK and the Bangladesh by using factor analysis. Five factors were extracted from factor analysis: ‘thoughts in cosmetics’, ‘brand link to social recognition and prestige’, ‘skin colour link to authority in society’, ‘group conformity’ and ‘personal-self’. It was noticed in the labelling process of the five factors that the extracted components were not exactly the same for both Bangladesh and the United Kingdom.

Publisher: name: International Journal of Economic Behavior
Year: 2016

description: This study aims at monitoring the role of Net loans for banks in terms of impact on total assets and, consequently, the trend of gross loans and the reserves for impaired loans in the period between 2005 and 2013. We also investigate the correlation between loans and their related Reserves for impaired loans, by using the Pearson correlation ratio. Data were extracted from Bankscope, a database containing comprehensive information on financial companies in Italy. Our findings raise important issues on the administrative supervision of banks and the financial system in general. A strong concern regarding the steady increase of impaired loans emerged and consequently the possibility of mergers has become one of the solutions for pursuing a more efficient risk policy.

Asymptotically preserving particle methods for strongly magnetizedplasmas in a torus
Creators: name: Filbet, Francis

Year: 2022
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: We propose and analyze a class of particle methods for the Vlasov equation with a strong external magnetic field in a torus configuration. In this regime, the time step can be subject to stability constraints related to the smallness of Larmor radius. To avoid this limitation, our approach is based on higher-order semi-implicit numerical schemes already validated on dissipative systems [3] and for magnetic fields pointing in a fixed direction [9, 10, 12]. It hinges on asymptotic insights gained in [11] at the continuous level. Thus, when the magnitude of the external magnetic field is large, this scheme provides a consistent approximation of the guiding-center system taking into account curvature and variation of the magnetic field. Finally, we carry out a theoretical proof of consistency and perform several numerical experiments that establish a solid validation of the method and its underlying concepts.
Universal asymptotic correlation functions for point group $\boldsymbol{C_{6v}}$ and an observation for triangular lattice $\boldsymbol{Q}$-state Potts model

description: We investigate universal forms for asymptotic correlation functions of off-critical systems that possess $C_{6v}$ symmetry following the argument for $C_{4v}$ symmetry in Phys.~Rev.~E{\bf 102},~032141. Unlike the $C_{4v}$ case, a minimal form exists that contains only two free parameters: the normalization constant and modulus. Using this form as a building block, we can construct next asymptotic forms to the minimal one. We perform large-scale Monte Carlo simulations of the triangular lattice $Q$-state Potts model above the transition temperature and successfully obtain numerical evidence to support a wide applicability of the minimal form to lattice models, including unsolvable ones. From the calculated minimal form, we derive the universal shape of equilibrium crystals in the honeycomb lattice Potts model described by an algebraic curve of genus 1. Although the curve differs from those obtained in the $C_{4v}$ case, the latters also have genus 1. We indicate that the birational equivalence concept can play an important role in comparing asymptotic forms for different point group symmetries, for example, $C_{6v}$ and $C_{4v}$.

description: This paper examines the plight of indigenous entrepreneurs and their battle for competitive edge with the Multinational Corporations in Nigeria. The research method is qualitative and analytical relying on previous scholarly works on this subject. The sourced data were analysed using critical discourse analysis. The authors found modernity theory most appropriate to underpin this study. The finding indicates that indigenous entrepreneurs lost competitive edge because of unequal balance of power with MNCs linked to lack of advanced technologies, poor managerial knowledge, low international social networks and inadequate institutional support from the government. The paper concludes that for indigenous entrepreneurs to regain its competitive edge with MNCs, the issues of advanced technologies, managerial knowledge, international social networks and institutional support must be addressed by the policymakers.

The Tourism Intermediation System: The Relationship between Travel Agencies and Tour Operators

Publisher: name: International Journal of Economic Behavior
Year: 2016

description: The study aims to investigate the characteristics of the relationships between travel agencies (TA) and tour operators (TO). Through an empirical analysis, we highlight the weight, the number, and the duration of the relationships that are created in the Italian tourism intermediation system. An empirical research was conducted on a sample of Italian travel agencies (202, covering all of the regions in Italy). Results show that, although the products supplied by TOs are fundamental to the realization of TA turnover, in most cases channel relationships are of short duration and highly variable. This could mean that vertical channel relationships do not sufficiently exploit areas of potential cooperation.
