description: A bijective map $r: X^2 \longrightarrow X^2$, where $X = \{x_1, ..., x_n \}$ is a finite set, is called a \emph{set-theoretic solution of the Yang-Baxter equation} (YBE) if the braid relation $r_{12}r_{23}r_{12} = r_{23}r_{12}r_{23}$ holds in $X^3.$ A non-degenerate involutive solution $(X,r)$ satisfying $r(xx)=xx$, for all $x \in X$, is called \emph{square-free solution}. There exist close relations between the square-free set-theoretic solutions of YBE, the semigroups of I-type, the semigroups of skew polynomial type, and the Bieberbach groups, as it was first shown in a joint paper with Michel Van den Bergh. In this paper we continue the study of square-free solutions $(X,r)$ and the associated Yang-Baxter algebraic structures -- the semigroup $S(X,r)$, the group $G(X,r)$ and the $k$- algebra $A(k, X,r)$ over a field $k$, generated by $X$ and with quadratic defining relations naturally arising and uniquely determined by $r$. We study the properties of the associated Yang-Baxter structures and prove a conjecture of the present author that the three notions: a square-free solution of (set-theoretic) YBE, a semigroup of I type, and a semigroup of skew-polynomial type, are equivalent. This implies that the Yang-Baxter algebra $A(k, X,r)$ is Poincaré-Birkhoff-Witt type algebra, with respect to some appropriate ordering of $X$. We conjecture that every square-free solution of YBE is retractable, in the sense of Etingof-Schedler.

User-generated nationalism : interactions with religion, race, and partisanship in everyday talk online
Creators: name: Shahin, Saif
Publisher: name: American University
Year: 2023

description: This article examines how the nationalist imagination structures cyberspace from the bottom up, or what I call user-generated nationalism. It also looks at the interplay between nationalism and other, non-spatial modes of social identification. My analysis of a month of tweets indicates that religious, racialized, and partisan identities are quite pronounced online, but they also tend to be conflated with nationalism. I argue that nationalism is not simply banal itself: because of its fixity in place and political correctness, it is used to lend legitimacy to and ‘banalize’ other identities. This dynamic is key to understanding the explosion of right-wing populism around the ‘world of nations’–especially the success of populist leaders in normalizing religious, racialized, and partisan identifications–and the central role being played by digital media in this process.

description: This work reports on the thermal stability of two amorphous CoFeB layers coupled antiferromagnetically via a thin Ru interlayer. The saturation field of the artificial ferrimagnet which is determined by the coupling, J, is almost independent on the annealing temperature up to more than 300 degree C. An annealing at more than 325 degree C significantly increases the coercivity, Hc, indicating the onset of crystallization.

description: In this paper, we first propose a general entanglement distillation protocol for three-particle W class state, which can concentrate the state (non-maximally entangled W state). The general protocol is mainly based on the unitary transformations on the auxiliary particles and the entangled particles, and a feasible physical scheme is suggested based on the cavity QED techniques. The protocol and scheme can be extended to the entanglement concentration of N-particle case.

The Utility of Coherent States and other Mathematical Methods in the Foundations of Affine Quantum Gravity
Creators: name: Klauder, John R.
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Affine quantum gravity involves (i) affine commutation relations to ensure metric positivity, (ii) a regularized projection operator procedure to accomodate first- and second-class quantum constraints, and (iii) a hard-core interpretation of nonlinear interactions to understand and potentially overcome nonrenormalizability. In this program, some of the less traditional mathematical methods employed are (i) coherent state representations, (ii) reproducing kernel Hilbert spaces, and (iii) functional integral representations involving a continuous-time regularization. Of special importance is the profoundly different integration measure used for the Lagrange multiplier (shift and lapse) functions. These various concepts are first introduced on elementary systems to help motivate their application to affine quantum gravity.

description: It has been argued that the symmetries of gravity at null infinity should include a Diff$(S^2)$ factor associated to diffeomorphisms on the celestial sphere. However, the standard phase space of gravity does not support the action of such transformations. Building on earlier work by Laddha and one of the authors, we present an extension of the phase space of gravity at null infinity on which Diff$(S^2)$ acts canonically. The Poisson brackets of supertranslation and Diff$(S^2)$ charges reproduce the generalized BMS algebra introduced in arXiv:1408.2228 .

description: Michael Walzer is one of the most distinguished political philosophers and social critics of this century. His ideas have had great import and influence in political philosophy and political discussion, yet very few of his ideas have been incorporated explicitly into the business ethics literature. We argue that Walzer’s work provides an important conceptual canvas for business ethics scholars that has not been adequately explored. Scholars in business ethics often borrow from political theory and philosophy to generate new insights and develop new substantive contributions. Many valuable theoretical resources are already used extensively—particularly Aristotle, Kant, Marx and a variety of utilitarian philosophers. Walzer offers another set of resources to bring to the conversation of what business ethics is and how business ethicists add value. This paper provides an opportunity to delve further into Walzer’s writings, particularly themes that are tied to business ethics, and to illustrate how his ideas can be extended to reshape our understanding of the field and develop new perspectives on ethical issues in commerce.

description: We generalize the standard quantum adiabatic approximation to the case of open quantum systems. We define the adiabatic limit of an open quantum system as the regime in which its dynamical superoperator can be decomposed in terms of independently evolving Jordan blocks. We then establish validity and invalidity conditions for this approximation and discuss their applicability to superoperators changing slowly in time. As an example, the adiabatic evolution of a two-level open system is analysed.

E-banking service quality, customer satisfaction and customer loyalty: Empirical study on Moroccan consumers
Creators: name: Lougmani, Chaymae
Publisher: name: zenodo
Year: 2024

description: This thesis aims to investigate consumers’ perceived quality of electronic banking, as well as its impact on customer satisfaction and loyalty in the context of Moroccan consumers. To achieve this objective, data was collected using a self-administered questionnaire from 500 respondents, of which 422 were deemed valid for analysis. The respondents are from different cities, genders, ages, educational backgrounds, and occupations. The data collected was analysed using the Partial Least Squares (PLS) analysis to evaluate the measurement and structural models. The results of hypothesis testing show that availability, security, relative advantage, and ease of use positively impact perceived service quality, whereas reliability has a negative impact. Perceived service quality has a positive effect on e-satisfaction and e-loyalty. In addition to this, e-satisfaction has a positive impact on e-loyalty. The findings could help us understand where e-banking service providers in Morocco should focus, and that is in improving service quality to enhance the customers satisfaction and loyalty. This topic is significant because of the rapid growth of e-banking services in Morocco and the need to understand the various factors influencing customer loyalty. The study focused on filling the gap in the literature available currently about and in Morocco by exploring the impact of e-banking service quality on e-loyalty and e-satisfaction in this specific context. Our findings suggest that e-banking service providers need to invest in improving service quality, especially reliability, availability, security, relative advantage, and ease of use. In addition to this, e-banking service providers should prioritize customer satisfaction to increase customer loyalty, which could lead to improved business performance.
The Effects Of Technology Driven Information Categories On Performance In Electronic Trading Markets

description: Electronic trading markets have evolved rapidly with continued adoption of new technologies and growing in-formation acquisition and processing capabilities. Traditional perspectives on trading performance adopted a mono-lithic view of information. Past research and practitioner heuristics posit that adopting new technologies and incorpo-rating more information should increase price efficiency and trading performance uniformity. However, along with technological change, information dynamics have evolved significantly resulting in immense growth in data volumes, and increased complexity of information categories. The present research explores behavioral trading performance under varying information category conditions and argues that unfettered technological developments and information consumption will not necessarily lead to consistent improvement in uniformity of trading performance. In this study, we employ an artificial stock market based economic experiment to examine the role of technol-ogy driven information categories in influencing trading decisions in electronic markets. Financial electronic markets are used as an information-rich mature markets representation to analyze information category driven trading perfor-mance. The results show that a variation of information categories can influence trading performance. The findings provide a basis to better understand behavioral phenomena in electronic markets and can be used to explain anomalies as well as to manage trading performance in electronic markets.

description: This paper addresses triggering of oscillatory structural forces via temperature variation across an aqueous dispersion of thermoresponsive poly(N-isopropylacrylamide) (PNIPAM) nanogels confined between silica surfaces. Oscillatory structural forces are a well-known phenomenon in colloidal science, caused by interactions between molecules or colloids. Modulation of these forces usually requires changing the internal parameters of the dispersion, such as ionic strength, particle concentration, and surface charge, or changing the properties of the confining walls, such as surface roughness, potential, or elasticity. All of these parameters are usually fixed and can only be changed via exchange of the sample or the complete experimental setup. Here, a new approach is presented, combining the characteristics of smart materials with the properties of nanoparticles, using negatively charged PNIPAM nanogels. Aqueous dispersions of these nanogels express no oscillatory structural forces in the initial state (20 °C), below the volume phase transition temperature (32 °C). Heating (60 °C) reduces the nanogel size and leads to a more negative ζ-potential, which triggers the onset of oscillatory structural forces.

Year: 2023

description: The Review of Financial Economics (RFE) has published empirical research covering all areas of financial economics since 1994. It celebrated its silver jubilee year of publishing in 2018. Using bibliometric techniques, we analyze the journal's impact, its prominent topics and most prolific authors including their affiliated institutions and countries. We also identify the bibliographic couplings of authors and their affiliated institutions and countries, co-citations of journals, and co-occurrences of the authors’ specified keywords. Our results show that about 83% of the published works receiving at least one citation between 1994 and 2018 and about 68% are co-authored. Among the important themes discussed in RFE, the words “stock”, “market,” and “risk” occupy central positions in RFE publications. Bibliographic coupling analysis identifies six clusters: (a) macroeconomic indicators, (b) investments, (c) financial institutions, (d) stock market, (e) corporate governance, and (f) corporate financial decisions.

description: HD 209458b was the first transiting planet discovered, and the first for which an atmosphere, in particular NaI, was detected. With time, it has become one of the most frequently studied planets, with a large diversity of atmospheric studies using low- and high-resolution spectroscopy. Here, we present transit spectroscopy observations of HD 209458b using the HARPS-N and CARMENES spectrographs. We fit the Rossiter-McLaughlin effect by combining radial velocity data from both instruments (nine transits in total), measuring a projected spin-orbit angle of $-1.6\pm0.3~{\rm deg}$. We also present the analysis of high-resolution transmission spectroscopy around the NaI region at $590~{\rm nm}$, using a total of five transit observations. In contrast to previous studies where atmospheric NaI absorption is detected, we find that for all of the nights, whether individually or combined, the transmission spectra can be explained by the combination of the centre-to-limb variation and the Rossiter-McLaughlin effect. This is also observed in the time-evolution maps and transmission light curves, but at lower signal-to-noise ratio. Other strong lines such as H$α$, CaII IRT, the MgI triplet region, and KI D1 are analysed, and are also consistent with the modelled effects, without considering any contribution from the exoplanet atmosphere. Thus, the transmission spectrum reveals no detectableNaI absorption in HD 209458b. We discuss how previous pioneering studies of this benchmark object may have overlooked these effects. While for some star-planet systems these effects are small, for other planetary atmospheres the results reported in the literature may require revision.

The Tidal Circularization Cutoff Period of the Old Open Cluster NGC188

description: Based on a sample of 45 main-sequence solar-type spectroscopic binaries we find the tidal circularization cutoff in the open cluster NGC 188 (age 7 Gyr) to be well-defined at a period of 15.0 days. When compared to shorter tidal circularization cutoff periods in the younger clusters M67 and the Hyades, this result establishes that tidal circularization processes are effective in solar-type main-sequence binaries for timescales longer than 1 Gyr. This result is in contrast to the theoretical prediction by Zahn & Bouchet that tidal circularization due to equilibrium tides is ineffective for late-type main sequence stars, and that tidal circularization cutoff periods are instead set only by pre-main-sequence tidal circularization. The NGC 188 cutoff period is also longer than can be explained by present theories of tidal circularization due to dynamical tides.

Dynamical decoupling of a geometric qubit

description: Quantum bits or qubits naturally decohere by becoming entangled with uncontrollable environments. Dynamical decoupling is thereby required to disentangle qubits from an environment by periodically reversing the qubit bases, but this causes rotation error to accumulate. Whereas a conventional qubit is rotated within the SU(2) two-level system, a geometric qubit defined in the degenerate subspace of a V-shaped SU(3) three-level system is geometrically rotated via the third ancillary level to acquire a geometric phase. We here demonstrate that, simply by introducing detuning, the dynamical decoupling of the geometric qubit on a spin triplet electron in a nitrogen-vacancy center in diamond can be made to spontaneously suppress error accumulation. The geometric dynamical decoupling extends the coherence time of the geometric qubit up to 1.9 ms, limited by the relaxation time, with 128 decoupling gates at room temperature. Our technique opens a route to holonomic quantum memory for use in various quantum applications requiring sequential operations

description: Silicates are an important component of interstellar dust and the structure of these grains -- amorphous versus crystalline -- is sensitive to the local physical conditions. We have studied the infrared spectra of a sample of ultra-luminous infrared galaxies. Here, we report the discovery of weak, narrow absorption features at 11, 16, 19, 23, and 28 microns, characteristic of crystalline silicates, superimposed on the broad absorption bands at 10 and 18 microns due to amorphous silicates in a subset of this sample. These features betray the presence of forsterite (Mg_2SiO_4), the magnesium-rich end member of the olivines. Previously, crystalline silicates have only been observed in circumstellar environments. The derived fraction of forsterite to amorphous silicates is typically 0.1 in these ULIRGs. This is much larger than the upper limit for this ratio in the interstellar medium of the Milky Way, 0.01. These results suggest that the timescale for injection of crystalline silicates into the ISM is short in a merger-driven starburst environment (e.g., as compared to the total time to dissipate the gas), pointing towards massive stars as a prominent source of crystalline silicates. Furthermore, amorphization due to cosmic rays, which is thought to be of prime importance for the local ISM, lags in vigorous starburst environments.

title: Functional characterisation of the T cell mediated anti-tumour response in a melanoma patient : identification of a HLA-DRβ1*10011 restricted unique antigen
Creators: name: Renkvist, Nicolina
Publisher: name: The Open University
Year: 2003

description: CD4+ T cells are central in regulating most adaptive immune responses and essential for sustaing CD8+ T cell activation and efficient tumour destruction. Therefore, a better understanding of the CD4+ T cell-mediated mechanisms involved in anti-tumour responses will be crucial to improve vaccination strategies. The objective of this thesis was to evaluate the anti-tumour CD4+ T cell response in a metastatic melanoma patient, Pt15392, disease free after 12 years from surgical removal of lymph node metastasis and who was previously shown to display a CD8+ T cell response against epitopes included in the TRP-2 and gp100 antigens. Several CD4+ T cell clones were isolated from the metastatic lymph nodes by limiting dilution assay. TCR analysis defined five groups of clones which all showed a strong TCR-dependent cytotoxic activity in response to in vitro stimulation with the autologous melanoma. Functional analysis demonstrated that all the isolated T cell clones recognised tumour cells in HLA-DR restricted fashion. In addition to exert a cytotoxic activity in response to tumor stimulation, these T cell clones released cytokines compatible with a Thl profile although they also specifically produced high amounts of IL-10. An invariant chain (Ii) - cDNA fusion library was constructed in an attempt to identify the melanoma antigen recognised by these CD4+ T cell clones. The screening resulted in the detection of a mutated form of the human protein tyrosine phosphatase receptor kappa (PTPR-k) gene, as a DRβ1*10011-restricted tumour antigen. All the T lymphocyte clones isolated in vitro were directed against a DRβ1*10011 presented peptide that contained the mutation while none of these T cells were activated by the wild type peptide. Thus, the favourable clinical outcome observed in Pt15392, may be correlated with a strong polyclonal CD4+ anti-tumour response. These data emphasise that continued monitoring of CD4+ T cell immune responses in cancer patients may allow the identification of new class II HLA-restricted antigens to be used for designing more effective cancer therapies.

description: We examine the global structure of scalar field critical collapse spacetimes using a characteristic double-null code. It can integrate past the horizon without any coordinate problems, due to the careful choice of constraint equations used in the evolution. The limiting sequence of sub- and supercritical spacetimes presents an apparent paradox in the expected Penrose diagrams, which we address in this paper. We argue that the limiting spacetime converges pointwise to a unique limit for all r>0, but not uniformly. The r=0 line is different in the two limits. We interpret that the two different Penrose diagrams differ by a discontinuous gauge transformation. We conclude that the limiting spacetime possesses a singular event, with a future removable naked singularity.

It also provides a useful theoretical laboratory for brane-world calculations in which kinetic terms are generated on the brane, since a lot is known about QED near boundaries.

description: In this paper, we study the question of quantization of quantum field theories in a general light-front frame. We quantize scalar, fermion as well as gauge field theories in a systematic manner carrying out the Hamiltonian analysis carefully. The decomposition of the fields into positive and negative frequency terms needs to be done carefully after which we show that the (anti) commutation relations for the quantum operators become frame independent. The frame dependence is completely contained in the functions multiplying these operators in the field decomposition. We derive the propagators from the vacuum expectation values of the time ordered products of the fields.

description: In a large scale trapped atomic ion quantum computer, high-fidelity two-qubit gates need to be extended over all qubits with individual control. We realize and characterize high-fidelity two-qubit gates in a system with up to 4 ions using radial modes. The ions are individually addressed by two tightly focused beams steered using micro-electromechanical system (MEMS) mirrors. We deduce a gate fidelity of 99.49(7)% in a two-ion chain and 99.30(6)% in a four-ion chain by applying a sequence of up to 21 two-qubit gates and measuring the final state fidelity. We characterize the residual errors and discuss methods to further improve the gate fidelity towards values that are compatible with fault-tolerant quantum computation.

description: We present the results of a numerical investigation of three-dimensional homogeneous and isotropic turbulence, stirred by a random forcing with a power law spectrum, $E_f(k)\sim k^{3-y}$. Numerical simulations are performed at different resolutions up to $512^3$. We show that at varying the spectrum slope $y$, small-scale turbulent fluctuations change from a {\it forcing independent} to a {\it forcing dominated} statistics. We argue that the critical value separating the two behaviours, in three dimensions, is $y_c=4$. When the statistics is forcing dominated, for $yy_c$, we find the same anomalous scaling measured in flows forced only at large scales. We connect these results with the issue of {\it universality} in turbulent flows.

description: Through analysis of single crystal neutron diffraction data, we present the magnetic structures of magnetoelectric Co4Nb2O9 under various magnetic fields. In zero-field, neutron diffraction experiments below TN=27 K reveal that the Co2+ moments order primarily along the a* direction without any spin canting along the c axis, manifested by the magnetic symmetry C2/c'. The moments of nearest neighbor Co atoms order ferromagnetically with a small cant away from the next nearest neighbor Co moments along the c axis. In the applied magnetic field H//a, three magnetic domains were aligned with their major magnetic moments perpendicular to the magnetic field with no indication of magnetic phase transitions. The influences of magnetic fields on the magnetic structures associated with the observed magnetoelectric coupling are discussed.

description: We present a new approach to scalable quantum computing--a ``qubus computer''--which realises qubit measurement and quantum gates through interacting qubits with a quantum communication bus mode. The qubits could be ``static'' matter qubits or ``flying'' optical qubits, but the scheme we focus on here is particularly suited to matter qubits. There is no requirement for direct interaction between the qubits. Universal two-qubit quantum gates may be effected by schemes which involve measurement of the bus mode, or by schemes where the bus disentangles automatically and no measurement is needed. In effect, the approach integrates together qubit degrees of freedom for computation with quantum continuous variables for communication and interaction.

description: Our ability to manipulate the behavior of complex networks depends on the design of efficient control algorithms and, critically, on the availability of an accurate and tractable model of the network dynamics. While the design of control algorithms for network systems has seen notable advances in the past few years, knowledge of the network dynamics is a ubiquitous assumption that is difficult to satisfy in practice, especially when the network topology is large and, possibly, time-varying. In this paper we overcome this limitation, and develop a data-driven framework to control a complex dynamical network optimally and without requiring any knowledge of the network dynamics. Our optimal controls are constructed using a finite set of experimental data, where the unknown complex network is stimulated with arbitrary and possibly random inputs. In addition to optimality, we show that our data-driven formulas enjoy favorable computational and numerical properties even compared to their model-based counterpart. Although our controls are provably correct for networks with linear dynamics, we also characterize their performance against noisy experimental data and in the presence of nonlinear dynamics, as they arise when mitigating cascading failures in power-grid networks and when manipulating neural activity in brain networks.

Modeling intermolecular and intramolecular modes of liquid water using multiple heat baths: Machine learning approach

description: The vibrational motion of molecules in dissipative environments, such as solvation and protein molecules, is composed of contributions from both intermolecular and intramolecular modes. The existence of these collective modes introduces difficulty into quantum simulations of chemical and biological processes. In order to describe the complex molecular motion of the environment in a simple manner, we introduce a system-bath model in which the intramolecular modes with anharmonic mode-mode couplings are described by a system Hamiltonian, while the other degrees of freedom, arising from the environmental molecules, are described by heat bath. Employing a machine-learning based approach, we determine not only the system parameters of the intramolecular modes but also the spectral distribution of the system-bath coupling to describe the intermolecular modes, using the atomic trajectories obtained from molecular dynamics (MD) simulations. The capabilities of the present approach are demonstrated for liquid water using MD trajectories calculated from the SPC/E model and the polarizable water model for intramolecular and intermolecular vibrational spectroscopies (POLI2VS) by determining the system parameters describing the symmetric-stretch, asymmetric-stretch and bend modes with intramolecular interactions and the bath spectral distribution functions for each intramolecular mode representing the interaction with the intra-molecular modes. From these results, we were able to elucidate the energy relaxation pathway between the intramolecular modes and the intermolecular modes in a non-intuitive manner.

description: We study characteristics of the relativistic equation of state (EOS) for collapse-driven supernovae, which is derived by relativistic nuclear many body theory. Recently the relativistic EOS table has become available as a new complete set of physical EOS for numerical simulations of supernova explosion. We examine this EOS table by using general relativistic hydrodynamics of the gravitational collapse and bounce of supernova cores. In order to study dense matter in dynamical situation, we perform simplified calculations of core collapse and bounce by following adiabatic collapse with the fixed electron fraction for a series of progenitor models. This is intended to give us ``approximate models'' of prompt explosion. We investigate the profiles of thermodynamical quantities and the compositions during collapse and bounce. We also perform the calculations with the Lattimer-Swesty EOS to compare the properties of dense matter. As a measure of the stiffness of the EOS, we examine the explosion energy of the prompt explosion with electron capture totally suppressed. We study the derivative of the thermodynamical quantities obtained by the relativistic EOS to discuss the convective condition in neutron-rich environment, which may be important in the delayed explosion.
