description: This paper aims to systematically study mystic reflection groups that emerged independently in the paper [Selecta Math. (N.S.) 14 (2009), 325-372, arXiv:0806.0867] by the authors and in the paper [Algebr. Represent. Theory 13 (2010), 127-158, arXiv:0806.3210] by Kirkman, Kuzmanovich and Zhang. A detailed analysis of this class of groups reveals that they are in a nontrivial correspondence with the complex reflection groups $G(m,p,n)$. We also prove that the group algebras of corresponding groups are isomorphic and classify all such groups up to isomorphism.

description: Ce travail prend sa source dans le contexte actuel de l’école suisse romande en s’intéressant aux choix politico-pédagogiques l’ayant influencé ces dernières années. Précisant sa focale autour des premiers degrés de la scolarité, soit les quatre années du Cycle I, deux « écoles » sont identifiées. Premièrement, une approche descendante et disciplinaire portée par HarmoS à travers le Plan d’Etudes Romand (PER), puis une approche plutôt ascendante tenant compte du développement de l’enfant et faisant la part belle au jeu de faire semblant. Ces deux perspectives n’envisageant pas tout à fait l’enseignement de la même manière, nous constatons que beaucoup d’enseignants peinent à tout concilier et se sentent quelque peu démunis et/ou pris en étau entre deux courants. Il ressort de leurs propos qu’ils ne savent pas comment gérer les périodes de jeu étant donné les objectifs à atteindre en temps et en heure. Pour pallier cet inconfort, nous avons proposé à des enseignantes d’implémenter un « Conceptual Playworld », une ingénierie didactique basée sur le jeu. En s’appuyant sur un album de jeunesse, un scénario de jeu comportant des défis est élaboré par les enseignantes, le tout dans la perspective d’objectifs d’apprentissage de leur choix, fixés en amont. A partir de cela, l’objectif de notre recherche est de réussir à décrire et à comprendre comment les enseignantes se positionnent par rapport aux moments de jeu. Durant la phrase d’expérimentation, conçue sous la forme d’une Lesson Study, nous avons ainsi pu nous rendre dans différentes classes, observer quel était le positionnement des enseignantes durant les moments de jeu. A l’aide d’une grille d’analyse inspirée de Devi (2018), des profils de positionnements ont été établis pour chaque période de jeu. En comparant et discutant ces profils, il a été possible d’en constater et d’en interpréter l’évolution. Nos résultats indiquent, entre autres, que les enseignantes n’ont pas assez d’outils pour gérer le jeu dans une perspective d’apprentissage.

description: We construct exact Kohn-Sham potentials for the ensemble density-functional theory (EDFT) from the ground and excited states of helium. The exchange-correlation (XC) potential is compared with the quasi-local-density approximation and both single determinant and symmetry eigenstate ghost-corrected exact exchange approximations. Symmetry eigenstate Hartree-exchange recovers distinctive features of the exact XC potential and is used to calculate the correlation potential. Unlike the exact case, excitation energies calculated from these approximations depend on ensemble weight, and it is shown that only the symmetry eigenstate method produces an ensemble derivative discontinuity. Differences in asymptotic and near-ground-state behavior of exact and approximate XC potentials are discussed in the context of producing accurate optical gaps.

description: The $\it{\Xi_{cc}^{++}\to \Xi_{c}^{'+}\pi^{+}}$ decay is observed using proton-proton collisions collected by the LHCb experiment at a centre-of-mass energy of $13\mathrm{\,Te\kern -0.1em V}$, corresponding to an integrated luminosity of $5.4\,\mathrm{fb}^{-1}$. The $\it{\Xi_{cc}^{++}\to \Xi_{c}^{'+}\pi^{+}}$ decay is reconstructed partially, where the photon from the $\it{\Xi_{c}^{'+} \to \Xi_{c}^{+}\gamma}$ decay is not reconstructed and the $pK^-\pi^+$ final state of the $\it{\Xi_{c}^{+}}$ baryon is employed. The $\it{\Xi_{cc}^{++}\to \Xi_{c}^{'+}\pi^{+}}$ branching fraction relative to that of the $\it{\Xi_{cc}^{++}\to \Xi_{c}^{+}\pi^{+}}$ decay is measured to be $1.41 \pm 0.17 \pm 0.10$, where the first uncertainty is statistical and the second systematic.

description: We explore dynamics of cosmological models with a nonminimally coupled scalar field evolving on a spatially flat Friedmann-Lemaitre-Robertson-Walker background. We consider cosmological models including the Hilbert-Einstein curvature term and the $N$ degree monomial of the scalar field nonminimally coupled to gravity. The potential of the scalar field is the $n$ degree monomial or polynomial. We describe several qualitatively different types of dynamics depending on values of power indices $N$ and $n$. We identify that three main possible pictures correspond to $n2N$ cases. Some special features connected with the important cases of $N=n$ (including the quadratic potential with quadratic coupling) and $n=2N$ (which shares its asymptotics with the potential of the Higgs-driven inflation) are described separately. A global qualitative analysis allows us to cover the most interesting cases of small $N$ and $n$ by a limiting number of phase-space diagrams. The influence of the cosmological constant to the global features of dynamics is also studied.

Significance of a software interoperability matrix for architectural engineering and construction industry

Publisher: name: Torrens University Australia

Subjects: Automation and technology in building and construction

description: Traditional project management applications are appeared working separately of their participating project teams and isolating the input of each team to both geometry and non-geometry of the project. With the introduction of Building Information Modelling (BIM), Architectural, Engineering and Construction (AEC) industry expected it would be a panacea as a tool to effectively collaborate project teams and to efficiently share geometry and non-geometry data relevant to not only design and construction but also covering the whole life-cycle of the project. All these BIM functions are relied on its automation capability; in other words, BIM vision totally discourages manual processing of data. As a result, good interoperability practice needs to pass data automatically between applications of different project teams. Many international associations are working in search of full interoperability among BIM players of the project; however, the goal is yet to succeed. The current study identifies the impact due to poor interoperability between applications and takes considerable effort to minimise or eliminate if possible. Software Interoperability Matrix (SIM) is the proposed solution delivering the outcome. Action research is the methodology adopted to develop SIM, in which researchers and professionals actively participated. Major industry contribution of SIM is to realise interoperability issues between BIM players prior to the project and upon identification, precautionary measures can be taken introducing new plug-ins or completely switching to new compatible application if it is the only solution.
Magnetoconductance of the Corbino disk in graphene: Chiral tunneling and quantum interference in the bilayer case

description: Quantum transport through an impurity-free Corbino disk in bilayer graphene is investigated analytically, by the mode-matching method for effective Dirac equation, in the presence of uniform magnetic fields. Similarly as in the monolayer case (see Refs. [1,2]), conductance at the Dirac point shows oscillations with the flux piercing the disk area $Φ_D$ characterized by the period $Φ_0=2\,(h/e)\ln(R_{\rm o}/R_{\rm i})$, where $R_{\rm o}$ ($R_{\rm i}$) is the outer (inner) disk radius. The oscillations magnitude depends either on the radii ratio or on the physical disk size, with the condition for maximal oscillations reading $R_{\rm o}/R_{\rm i}\simeq\left[\,R_{\rm i}t_{\perp}/(2\hbar{}v_{F})\,\right]^{4/p}$ (for $R_{\rm o}/R_{\rm i}\gg{}1$), where $t_\perp$ is the interlayer hopping integral, $v_F$ is the Fermi velocity in graphene, and $p$ is an {\em even} integer. {\em Odd}-integer values of $p$ correspond to vanishing oscillations for the normal Corbino setup, or to oscillations frequency doubling for the Andreev-Corbino setup. At higher Landau levels (LLs) magnetoconductance behaves almost identically in the monolayer and bilayer cases. A brief comparison with the Corbino disk in 2DEG is also provided in order to illustrate the role of chiral tunneling in graphene.

description: The magnetization reversal time of ferromagnetic nanoparticles is investigated in the very low damping regime. The energy-controlled diffusion equation rooted in a generalization of the Kramers escape rate theory for point Brownian particles in a potential to the magnetic relaxation of a macrospin, yields the reversal time in closed integral form. The latter is calculated for a nanomagnet with uniaxial anisotropy with a uniform field applied at an angle to the easy axis and for a nanomagnet with biaxial anisotropy with the field along the easy axis. The results completely agree with those yielded by independent numerical and asymptotic methods.

description: Avoidance and heightened responses to perceived threats are key features of anxiety disorders. These disorders are characterised by inflexibility in dynamically updating behavioural and physiological responses to aversively conditioned cues or environmental contexts which are no longer objectively threatening, often manifesting in perseverative avoidance. However, less is known about how anxiety disorders might differ in adjusting to threat and safety shifts in the environment or how idiosyncratic avoidance responses are learned and persist. Twenty-eight patients with generalised anxiety disorder (GAD), without DSM co-morbidities, and 27 matched healthy controls were administered two previously established paradigms: Pavlovian threat reversal and shock avoidance habits through overtraining (assessed following devaluation with measures of perseverative responding). For both tasks we used subjective report scales and skin conductance responses (SCR). In the Pavlovian threat reversal task, patients with GAD showed a significantly overall higher SCR as well as a reduced differential SCR response compared to controls in the early but not late reversal phase. During the test of habitual avoidance responding, GAD patients did not differ from controls in task performance, habitual active avoidance responses during devaluation, or corresponding SCR during trials, but showed a trend toward more abstract confirmatory subjective justifications for continued avoidance following the task. GAD patients exhibited significantly greater skin conductance responses to signals of threat than controls, but did not exhibit the major deficits in reversal and safety signal learning shown previously by patients with OCD. Moreover, this patient group, again unlike OCD patients, did not show evidence of altered active avoidance learning or enhanced instrumental avoidance habits. Overall, these findings indicate no deficits in instrumental active avoidance or persistent avoidance habits, despite enhanced responses to Pavlovian threat cues in GAD. They suggest that GAD is characterised by passive, and not excessively rigid, avoidance styles.

description: We use the latest dataset of supernova (SN) host galaxies to investigate how the host properties -- stellar mass, star formation rate, metallicity, absolute magnitude, and colour -- differ across SN types, with redshift-driven selection effects controlled. SN Ib and Ic host galaxies, on average, are more massive, metal-rich, and redder than SN II hosts. For subtypes, SN Ibn and Ic-BL have bluer hosts than their normal SN Ib and Ic siblings; SN IIb has consistent host properties with SN Ib, while hosts of SN IIn are more metal-rich than those of SN II. Hydrogen-deficient superluminous supernovae feature bluer and lower luminosity hosts than most subtypes of core-collapse supernova (CC SN). Assuming simple proportionality of CC SN rates and host star formation rates (SFRs) does not recover the observed mean host properties; either a population of long-lived progenitors or a metallicity-dependent SN production efficiency better reproduces the observed host properties. Assuming the latter case, the rates of SN II are insensitive to host metallicity, but the rates of SN Ib and Ic are substantially enhanced in metal-rich hosts by a factor of ~10 per dex increase in metallicity. Hosts of SN Ia are diverse in their observed properties; subtypes including SN Ia-91T, Ia-02cx, and Ia-CSM prefer star-forming hosts, while subtypes like SN Ia-91bg and Ca-rich prefer quiescent hosts. The rates of SN Ia-91T, Ia-02cx, and Ia-CSM are closely dependent on, or even proportional to, their host SFRs, indicating relatively short-lived progenitors. Conversely, the rates of SN Ia-91bg and Ca-rich transients are proportional to the total stellar mass, favoring long-lived progenitors.

description: A selective and efficient method for the synthesis of previously unknown mono-adducts of the C60 fullerene with fused morpholine moieties has been developed based on the reaction of C60 with amino alcohols, including biogenic amines (2-aminoethanol, 2-amino-1-phenylethanol, noradrenaline, and adrenaline), in a mixed solvent (toluene/DMF) at room temperature under air and ultrasonication. The radical anion C60•‒ (g = 2.0004 and ΔH1/2 = 3.4 G) was detected as a key intermediate by the EPR method upon the synthesis of the C60–morpholine adduct. This intermediate results due to the one-electron transfer from 2-aminoethanol onto the C60 core.

description: The rapid growth of the Internet has led to a revolution in the relationship between customers and companies. After the first experiences on social media platforms, companies started hosting their own online customer networks where formerly passive consuming customers are able to connect, share, and cooperate with each other and the company. This social engagement of customers is generally considered as an incredible value for the hosting company. However, while previous research regularly takes a positive relationship between users’ social engagement and customer profitability in online customer networks for granted, there is still a lack of research rigorously analyzing this aspect in detail. Against this background, the aim of our paper is to provide an in-depth investigation of the relationship between users’ social engagement and customer profitability in online customer networks using a unique dataset of a German direct banking institution. This leads to interesting results that do not support either existing statements in literature or best current practices. Indeed, in our case we do not generally observe significant higher social engagement for “buyers” compared with “nonbuyers”.

Afin de comparer les trajectoires des Suisses et des jeunes issu·e·s de la migration. Cette recherche qualitative longitudinale, nous permet de contraster différents profils et d’analyser les possibles facteurs de vulnérabilité à la lumière des parcours scolaires et migratoires. Les résultats ont prouvé que la moitié des jeunes ayant eu une transition indirecte vers l’apprentissage, par un passage à l’École de Transition ou par une année au gymnase, ont trouvé un premier emploi directement après l’obtention de leur diplôme. Cependant, deux diplômé·e·s se sont inscrit·e·s au chômage parce qu’ils/elles ont eu de la difficulté à trouver un poste pendant le COVID-19. Deux autres, ne voulant pas perdre leur autonomie financière ont décidé de travailler dans un autre domaine en dépit de leurs compétences professionnelles. Aussi, nous avons relevé que dans le passage vers l’apprentissage les parents sont une ressource importante (Ruiz & Goastellec, 2016) pour les deux groupes de population. Néanmoins, chez les jeunes isssu·e·s de la migration le soutien instrumental est faible ou inexistant contrairement aux suisse·sse·s. Alors que lors de la recherche d’un premier emploi, les deux groupes peuvent s’appuyer sur leur réseau social, car ils/elles ont des liens amicaux et professionnels stables.

description: The intrinsic dimensionality of an inverse problem is affected by prior information, the accuracy and number of observations, and the smoothing properties of the forward operator. From a Bayesian perspective, changes from the prior to the posterior may, in many problems, be confined to a relatively low-dimensional subspace of the parameter space. We present a dimension reduction approach that defines and identifies such a subspace, called the "likelihood-informed subspace" (LIS), by characterizing the relative influences of the prior and the likelihood over the support of the posterior distribution. This identification enables new and more efficient computational methods for Bayesian inference with nonlinear forward models and Gaussian priors. In particular, we approximate the posterior distribution as the product of a lower-dimensional posterior defined on the LIS and the prior distribution marginalized onto the complementary subspace. Markov chain Monte Carlo sampling can then proceed in lower dimensions, with significant gains in computational efficiency. We also introduce a Rao-Blackwellization strategy that de-randomizes Monte Carlo estimates of posterior expectations for additional variance reduction. We demonstrate the efficiency of our methods using two numerical examples: inference of permeability in a groundwater system governed by an elliptic PDE, and an atmospheric remote sensing problem based on Global Ozone Monitoring System (GOMOS) observations.

description: In this work, we developed a simple route to synthesize green fluorescence carbon nanoparticles (FCPs) at room temperature with dopamine and p-phenylenediamine as raw materials. The FCPs exhibited a salient fluorescence emission peak at 525 nm and well stability in the intricate surroundings. Only Cu2+ ions could significantly inhibited the fluorescence of FCPs and could be successfully detected in the concentration scope of 0–200 µmol·L−1 based on the fluorescence quenching of FCPs. The Cu2+ ion-quenched fluorescence of FCPs system can be further recovered by the addition of dipicolinic acid (DPA) and could be utilized for DPA detection within the dynamic scope of 10–150 µmol·L−1.

description: In the chiral symmetric phase, the polarized instanton--anti-instanton molecule pairing induces a nontrivial repulsive interaction in the iso-scalar axial-vector channel. As a consequence, one unusual property is observed that in the chiral restoration phase, there is a first order phase transition for the spontaneous generation of local CP violation and chiral imbalance. Furthermore, it is found that external magnetic fields will lower the critical temperature for the local CP-odd phase transition and catalyze the chiral imbalance, which destroys the chiral condensate with pairing quarks between different chiralities. A reasonable strength of the repulsive interaction in the iso-scalar axial-vector channel can naturally explain the inverse magnetic catalysis around the critical temperature under external magnetic fields.

description: We present an analysis of 152,355 radio sources identified in the second data release of the LOFAR Two Metre Sky Survey (LoTSS-DR2) with Sloan Digital Sky Survey (SDSS) spectroscopic redshifts in the range 0.00 < z < 0.57. Using Monte Carlo simulations we determine the reliability of each source exhibiting an excess in radio luminosity relative to that predicted from their Ha emission, and, for a subset of 124,023 sources we combine this measurement with a full BPT analysis. Using these two independent diagnostics we determine the reliability of each source hosting a supermassive black hole of high or low Eddington-scaled accretion rate, and combine the measurements to determine the reliability of sources belonging to each of four physical classes of objects: star forming galaxies (SFGs), radio-quiet active galactic nuclei (RQAGN), and high- or low-excitation radio galaxies (HERGs or emission-line LERGs). The result is a catalogue which enables user-defined samples of radio sources with a reliability threshold suited to their science goal e.g. prioritising purity or completeness. Here we select high-confidence samples of radio sources (>90% reliability) to report: 38,588 radio-excess AGN in the LoTSS DR2 sample (362 HERGs, and 12,648 emission-line LERGs), together with 38,729 SFGs, and 18,726 RQAGN. We validate these results through comparison to literature using independent emission-line measurements, and to widely-adopted WISE photometric selection techniques. While our use of SDSS spectroscopy limits our current analysis to ~4 percent of the LoTSS-DR2 catalogue, our method is directly applicable to data from the forthcoming WEAVE-LOFAR survey which will obtain over a million spectra of 144 MHz selected sources.

description: Small and medium sized (SMEs) companies are a pillar of the Bavarian economy. With business process management (BPM) providing an important competitive advantage in the globalized economy, the adap-tion of BPM by SMEs has societal relevance. However, the reasons why, or why not, SMEs implement BPM measures are still not fully understood. Previous research addressed this topic either breadthwise as surveys or in depth as case studies, and thus only has a limited perspective. Therefore, in our work, we carry out a mixed method analysis. We conduct 10 case studies to analyse the current state of adoption as well as the reasons for or against implementing further BPM measures. The insights gained guide the design of the subsequent survey. 114 results allow us to evaluate how widespread a particular reason may be. Lastly, the combined discussion of the results of both the case studies and surveys allow us to identify reasons that hinder or foster BPM adoption in SMEs, which are in-depth as well as generalizable. The study results are analyzed to derive propositions to research and practitioners alike that support SMEs to introduce further measures of BPM and improve their global competitiveness. For example, we could identify that BPM is in some cases enforced by customers, that stricter certifications are nec-essary, and that BPM trainings aligned to the needs of SMEs are desirable.

description: The potential for cascading failure in power systems adds substantially to overall reliability risk. Monte Carlo sampling can be used with a power system model to estimate this impact, but doing so is computationally expensive. This paper presents a new approach to estimating the risk of large cascading blackouts triggered by multiple contingencies. The method uses a search algorithm (Random Chemistry) to identify blackout-causing contingencies, and then combines the results with outage probabilities to estimate overall risk. Comparing this approach with Monte Carlo sampling for two test cases (the IEEE RTS-96 and a 2383 bus model of the Polish system) illustrates that the new approach is at least two orders of magnitude faster than Monte Carlo, without introducing measurable bias. Moreover, the approach enables one to compute the sensitivity of overall blackout risk to individual component-failure probabilities in the initiating contingency, allowing one to quickly identify low-cost strategies for reducing risk. By computing the sensitivity of risk to individual initial outage probabilities for the Polish system, we found that reducing three line-outage probabilities by 50% would reduce cascading failure risk by 33%. Finally, we used the method to estimate changes in risk as a function of load. Surprisingly, this calculation illustrates that risk can sometimes decrease as load increases.

description: For total reflection, the Goos-Hanchen (GH) shift is proportional to the wavelength of the laser beam. At critical angles, such a shift is instead proportional to the square root of the product of the beam waist and wavelength. By using the stationary phase method (SPM) and, when necessary, numerical calculations, we present a detailed analysis of the frequency crossover for the GH shift. The study, done in different incidence regions, sheds new light on the validity of the analytic formulas found in literature.

description: We develop an agent-based model of strategic link formation in Research and Development (R&D) networks. Empirical evidence has shown that the growth of these networks is driven by mechanisms which are both endogenous to the system (that is, depending on existing alliances patterns) and exogenous (that is, driven by an exploratory search for newcomer firms). Extant research to date has not investigated both mechanisms simultaneously in a comparative manner. To overcome this limitation, we develop a general modeling framework to shed light on the relative importance of these two mechanisms. We test our model against a comprehensive dataset, listing cross-country and cross-sectoral R&D alliances from 1984 to 2009. Our results show that by fitting only three macroscopic properties of the network topology, this framework is able to reproduce a number of micro-level measures, including the distributions of degree, local clustering, path length and component size, and the emergence of network clusters. Furthermore, by estimating the link probabilities towards newcomers and established firms from the data, we find that endogenous mechanisms are predominant over the exogenous ones in the network formation, thus quantifying the importance of existing structures in selecting partner firms.

description: We compute the decay constants of the lowest ccbar-states with quantum numbers J(PC)=0(-+) [eta_c], 1(--) [J/psi], and 1(+-) [hc] by using lattice QCD and QCD sum rules. We consider the coupling of J/psi to both the vector and tensor currents. Lattice QCD results are obtained from the unquenched (Nf=2) simulations using twisted mass QCD at four lattice spacings, allowing us to take the continuum limit. On the QCD sum rule side we use the moment sum rules. The results are then used to discuss the rate of eta_c --> gamma gamma decay, and to comment on the factorization in B --> X K decays, with X being either eta_c or J/psi.

Scattering Amplitudes
Spontaneous Symmetry Breaking
Space-Time Sym- metries

description: Poincar\'e invariance is a well-tested symmetry of nature and sits at the core of our description of relativistic particles and gravity. At the same time, in most systems Poincar\'e invariance is not a symmetry of the ground state and is hence broken spontaneously. This phenomenon is ubiquitous in cosmology where Lorentz boosts are spontaneously broken by the existence of a preferred reference frame in which the universe is homogeneous and isotropic. This motivates us to study scattering amplitudes without requiring invariance of the interactions under Lorentz boosts. In particular, using on-shell methods and assuming massless, relativistic and luminal particles of any spin, we show that the allowed interactions around Minkowski spacetime are severely constrained by unitarity and locality in the form of consistent factorization. The existence of an interacting massless spin-2 particle enforces (analytically continued) three-particle amplitudes to be Lorentz invariant, even those that do not involve a graviton, such as cubic scalar couplings. We conjecture this to be true for all n-particle amplitudes. Also, particles of spin S > 2 cannot self-interact nor can be minimally coupled to gravity, while particles of spin S > 1 cannot have electric charge. Given the growing evidence that free gravitons are well described by massless, luminal relativistic particles, our results imply that cubic graviton interactions in Minkowski must be those of general relativity up to a unique Lorentz-invariant higher-derivative correction of mass dimension 9. Finally, we point out that consistent factorization for massless particles is highly IR sensitive and therefore our powerful at-space results do not straightforwardly apply to curved spacetime.
