description: The formation of double and triple C-C bonds from the processing of pure c-C6H12 (cyclohexane) and mixed H2O:NH3:c-C6H12 (1:0.3:0.7) ices by highly-charged, and energetic ions (219 MeV O^{7+} and 632 MeV Ni^{24+}) is studied. The experiments simulate the physical chemistry induced by medium-mass and heavy-ion cosmic rays in interstellar ices analogs. The measurements were performed inside a high vacuum chamber at the heavy-ion accelerator GANIL (Grand Accelératéur National d'Ions Lourds) in Caen, France. The gas samples were deposited onto a polished CsI substrate previously cooled to 13 K. In-situ analysis was performed by a Fourier transform infrared (FTIR) spectrometry at different ion fluences. Dissociation cross section of cyclohexane and its half-life in astrophysical environments were determined. A comparison between spectra of bombarded ices and young stellar sources indicates that the initial composition of grains in theses environments should contain a mixture of H2O, NH3, CO (or CO2), simple alkanes, and CH3OH. Several species containing double or triple bounds were identified in the radiochemical products, such as hexene, cyclohexene, benzene, OCN-, CO, CO2, as well as several aliphatic and aromatic alkenes and alkynes. The results suggest an alternative scenario for the production of unsaturated hydrocarbons and possibly aromatic rings (via dehydrogenation processes) in interstellar ices induced by cosmic ray bombardment.

description: The colour fields created by the static tetraquark and pentaquark systems are computed in quenched SU(3) lattice QCD, with gauge invariant lattice operators, in a 24^3 x 48 lattice at beta=6.2 . We generate our quenched configurations with GPUs, and detail the respective benchmanrks in different SU(N) groups. While at smaller distances the coulomb potential is expected to dominate, at larger distances it is expected that fundamental flux tubes, similar to the flux-tube between a quark and an antiquark, emerge and confine the quarks. In order to minimize the potential the fundamental flux tubes should connect at 120o angles. We compute the square of the colour fields utilizing plaquettes, and locate the static sources with generalized Wilson loops and with APE smearing. The tetraquark system is well described by a double-Y-shaped flux-tube, with two Steiner points, but when quark-antiquark pairs are close enough the two junctions collapse and we have an X-shaped flux-tube, with one Steiner point. The pentaquark system is well described by a three-Y-shaped flux-tube where the three flux the junctions are Steiner points.

description: To investigate the universal structure of interactions in financial dynamics, we analyze the cross-correlation matrix C of price returns of the Chinese stock market, in comparison with those of the American and Indian stock markets. As an important emerging market, the Chinese market exhibits much stronger correlations than the developed markets. In the Chinese market, the interactions between the stocks in a same business sector are weak, while extra interactions in unusual sectors are detected. Using a variation of the two-factor model, we simulate the interactions in financial markets.

description: There is much effort at all scales invested in preserving and adding value to data within projects and for long-term re-use. As the related communities and services develop it is important that they can take stock of their development to ensure planning for long term development and viability (in terms of their factors such as staffing, funding etc) and plan for future service adjustments (including potential for service retirement). Such reflective practice is aided by frameworks such as the WGISS Data Management and Stewardship maturity index and the Core Trust Seal. However, these exist in a wider context of a necessary growing professionalisation of data stewardship as a whole, be that at a service level, drawing in aspects of service initialisation, development, business cases etc, or for individuals in regards to career pathways, training curricular etc.

 

Since 2020 the Research Data Alliance’s Professionalising Data Stewardship Interest Group has undertaken a range of activities to support the wider standing of this profession. The Interest Group’s ‘Models of Data Stewardship’ survey report and dataset provides insights into practices and experiences across a wide range of service types (from project level/single-domain to multi-national/multi-domain and generic services) based on a conceptual model of data stewardship services. Meanwhile, the career paths (survey report in production) and training interest task group outputs (landscape Report and Matrix) provide material useful for those concerning staff development and training needs. These outputs support the continuing work within the Business Case Task Group and Terminology Task groups, seeking to provide common community-wide agreed terminology around the varied aspects of data stewardship in all its forms and aiding services to develop and be sustained.

 

The Interest group is now entering its next phase of work and seeking further engagement with the wider community to build on the outputs achieved to date. This poster will provide further details on the group’s aims and outputs and seek to open up collaborations with interested parties.

description: We derive the best characterization to date of the properties of radio quiescent massive galaxy clusters through a statistical analysis of their average synchrotron emissivity. We stacked 105 radio images of clusters from the 843 MHz SUMSS survey, all with X-ray luminosities greater than 1.0E+44 erg/s and redshifts z < 0.2, after removing point-source contamination and rescaling to a common physical size. Each stacked cluster individually shows no significant large-scale diffuse radio emission at current sensitivity levels. Stacking of sub-samples leads to the following results: (i) clusters with L_{X} > 3.0E+44 erg/s show a 6-sigma detection of Mpc-scale diffuse emission with a 1.4 GHz luminosity of 2.4\pm0.4 x 1.0E+23 W/Hz. This is 1.5-2 times lower than the upper limits for radio quiescent clusters from the GMRT Radio Halo Survey (Venturi et al. 2008), and is the first independent confirmation of radio halo bi-modality; (ii) clusters with low X-ray concentrations have a mean radio luminosity (2.6\pm0.6 x 1.0E+23 W/Hz) that is at least twice that of high X-ray concentration clusters, and (iii) both of these detections are likely close to the low-level "off-state" of GRHs in most or all luminous X-ray clusters, and not due to contributions from a much smaller subset of "on-state" GRHs following the radio/X-ray luminosity correlation. Upcoming deep radio surveys will conclusively distinguish between these two options. We briefly discuss possible origins for the "off-state" emission and its implications for magnetic fields in most or all luminous X-ray clusters.

description: Measurement-induced nonlocality (MiN), introduced by Luo and Fu [Phys. Rev. Lett. 106(2011)120401], is a kind of quantum correlation that beyond entanglement and even beyond quantum discord. Recently, we extended MiN to infinite-dimensional bipartite system [arXiv:1107.0355]. MiN is defined over one-sided projective measurements. In this letter we introduce a measurement-induced nonlocality over two-sided projective measurements. The nullity of this two-sided MiN is characterized, a formula for calculating two-sided MiN for pure states is proposed, and a lower bound of (two-sided) MiN for maximally entangled mixed states is given. In addition, we find that (two-sided) MiN is not continuous. The two-sided geometric measure of quantum discord (GMQD) is introduced in [Phys. Lett. A 376(2012)320--324]. We extend it to infinite-dimensional system and then compare it with the two-sided MiN. Both finite- and infinite-dimensional cases are considered.

description: A recent paper states that ultraviolet backradiation from the solar transition region and upper chromosphere strongly affects the degree of ionization of minority stages at the top of the photosphere, i.e., in the temperature minimum of the one-dimensional static model atmospheres presented in that paper. We show that this claim is incompatible with bservations and we demonstrate that the pertinent ionization balances are instead dominated by outward photospheric radiation, as in older static models. We then analyze the formation of Halpha in the above model and show that it has significant backradiation across the opacity gap by which Halpha differs from other strong scatttering lines.

Measuring nonadiabaticity of molecular quantum dynamics with quantum fidelity and with its efficient semiclassical approximation

description: We propose to measure nonadiabaticity of molecular quantum dynamics rigorously with the quantum fidelity between the Born-Oppenheimer and fully nonadiabatic dynamics. It is shown that this measure of nonadiabaticity applies in situations where other criteria, such as the energy gap criterion or the extent of population transfer, fail. We further propose to estimate this quantum fidelity efficiently with a generalization of the dephasing representation to multiple surfaces. Two variants of the multiple-surface dephasing representation (MSDR) are introduced, in which the nuclei are propagated either with the fewest-switches surface hopping (FSSH) or with the locally mean field dynamics (LMFD). The LMFD can be interpreted as the Ehrenfest dynamics of an ensemble of nuclear trajectories, and has been used previously in the nonadiabatic semiclassical initial value representation. In addition to propagating an ensemble of classical trajectories, the MSDR requires evaluating nonadiabatic couplings and solving the Schrödinger (or more generally, the quantum Liouville-von Neumann) equation for a single discrete degree of freedom. The MSDR can be also used to measure the importance of other terms present in the molecular Hamiltonian, such as diabatic couplings, spin-orbit couplings, or couplings to external fields, and to evaluate the accuracy of quantum dynamics with an approximate nonadiabatic Hamiltonian. The method is tested on three model problems introduced by Tully, on a two-surface model of dissociation of NaI, and a three-surface model including spin-orbit interactions. An example is presented that demonstrates the importance of often-neglected second-order nonadiabatic couplings.

Factor modeling for high-dimensional time series: Inference for the number of factors
Creators: name: Lam, Clifford
name: Yao, Qiwei
Publisher: name: arXiv
Year: 2012
Subjects: subject: Statistics Theory (math.ST)
subject: FOS: Mathematics

description: This paper deals with the factor modeling for high-dimensional time series based on a dimension-reduction viewpoint. Under stationary settings, the inference is simple in the sense that both the number of factors and the factor loadings are estimated in terms of an eigenanalysis for a nonnegative definite matrix, and is therefore applicable when the dimension of time series is on the order of a few thousands. Asymptotic properties of the proposed method are investigated under two settings: (i) the sample size goes to infinity while the dimension of time series is fixed; and (ii) both the sample size and the dimension of time series go to infinity together. In particular, our estimators for zero-eigenvalues enjoy faster convergence (or slower divergence) rates, hence making the estimation for the number of factors easier. In particular, when the sample size and the dimension of time series go to infinity together, the estimators for the eigenvalues are no longer consistent. However, our estimator for the number of the factors, which is based on the ratios of the estimated eigenvalues, still works fine. Furthermore, this estimation shows the so-called "blessing of dimensionality" property in the sense that the performance of the estimation may improve when the dimension of time series increases. A two-step procedure is investigated when the factors are of different degrees of strength. Numerical illustration with both simulated and real data is also reported.

description: The quasi-particle energy spectrum of the Hartree-Fock-Bogoliubov (HFB) equations contains discrete bound states, resonances, and non-resonant continuum states. We study the structure of the unbound quasi-particle spectrum of weakly bound nuclei within several methods that do not rely on imposing scattering or outgoing boundary conditions. Various approximations are examined to estimate resonance widths. It is shown that the stabilization method works well for all HFB resonances except for very narrow ones. The Thomas-Fermi approximation to the non-resonant continuum has been shown to be very effective, especially for coordinate-space HFB calculations in large boxes that involve huge amounts of discretized quasi-particle continuum states.

The Role of Fairness and Basic Psychological Needs in Understanding Dyslexic Students’ Emotions in Classroom Assessment
Creators: Lia M. Daniels, Lauren D. Goegan, and Patti C. Parker
Publisher: name: University of Alberta Library
Year: 2023

Post-secondary students with learning disabilities like dyslexia experience a wide range of emotions related to classroom assessment, perhaps in part because assessment may feel unfair and undermine principles related to wellbeing. To mitigate negative emotions, researchers tend to focus on teaching students how to cope with test anxiety and exam stress or encouraging instructors to improve assessment formats. These approaches, however, do not attend to the psychological experience of assessment. The purpose of this study was to examine associations amongst perceived fairness, three basic psychological needs, and six discrete emotions in the domain of classroom assessment. Results of a parallel multiple mediator analysis showed that perceptions of fairness were positively associated with psychological need satisfaction. In turn, satisfaction of competence and autonomy were related to students’ emotions; whereas, relatedness was not. We describe specific recommendations for supporting students’ wellbeing in assessment with particular attention to nuances for students with dyslexia.

description: We present a way to evaluate the scattering of unstable particles quantized in a finite volume with the aim of extracting physical observables for infinite volume from lattice data. We illustrate the method with the $πρ$ scattering which generates dynamically the axial-vector $a_1(1260)$ resonance. Energy levels in a finite box are evaluated both considering the $ρ$ as a stable and unstable resonance and we find significant differences between both cases. We discuss how to solve the problem to get the physical scattering amplitudes in the infinite volume, and hence phase shifts, from possible lattice results on energy levels quantized inside a finite box.

Strangeness production analysis in simulated proton-proton collisions at the LHC with the new ALICE Run 3 computing environment

description: During the second long shutdown of the Large Hadron Collider (end of 2018 to middle of 2022), the ALICE detector was the subject of a complete reworking of its detector, reconstruction and analysis software, to prepare for the analysis of collisions happening at an increased interaction rate and recorded continuously, without trigger. The recording in October 2021 of the pilot beam proton-proton collisions at sqrt{s} = 900 GeV and the production of Monte Carlo data simulating those beam conditions allowed an extensive test of this new detector as well as of the reconstruction and analysis tools. This work focuses in this context on the analysis of the V0 decays K0S and Lambda in a Monte Carlo simulation of the pilot beam collisions. Those decays are building blocks for the analysis of strange decays in general, a valuable probe of the quark-gluon plasma. Their transverse momentum spectra are computed from the data reconstructed using the new analysis software, and compared to the initial spectra generated by the simulation. The analysis suite succeeds in reproducing the generated spectrum. The lower reconstruction efficiency compared to analyses done before the upgrade prompted a loosening of the reconstruction cuts despite leading to additional computing load. An imperfection in the calibration of the first preliminary results from real data is also observed.

description: In recent years, Chinese language instruction is getting more and more popular in German middle school education, it also encouraged research interests in the didactical principles and methods of teaching Chinese as a foreign language. Regarding common prejudices in foreign language education, this paper uses a practical lesson as example to explain the possibilities of applying grammar knowledge by developing communicative-functional approach. It provides a comprehensive formula combining grammar explanation and real-situation practice in order to improve grammatically accurate communication skills and reveals the process from using reference knowledge, followed by self-induction of grammatical rules and its consolidation, to the state of flexible and vivid language use. At the same time, it discusses the related teaching strategies in grammar comparison, mood steering, contextualized language practice, cognitive optimization as well as creativity motivation.

description: Source localization by matched-field processing (MFP) generally involves solving a number of computationally intensive partial differential equations. This paper introduces a technique that mitigates this computational workload by "compressing" these computations. Drawing on key concepts from the recently developed field of compressed sensing, it shows how a low-dimensional proxy for the Green's function can be constructed by backpropagating a small set of random receiver vectors. Then, the source can be located by performing a number of "short" correlations between this proxy and the projection of the recorded acoustic data in the compressed space. Numerical experiments in a Pekeris ocean waveguide are presented which demonstrate that this compressed version of MFP is as effective as traditional MFP even when the compression is significant. The results are particularly promising in the broadband regime where using as few as two random backpropagations per frequency performs almost as well as the traditional broadband MFP, but with the added benefit of generic applicability. That is, the computationally intensive backpropagations may be computed offline independently from the received signals, and may be reused to locate any source within the search grid area.

description: Quantum computers can in principle simulate quantum physics exponentially faster than their classical counterparts, but some technical hurdles remain. Here we consider methods to make proposed chemical simulation algorithms computationally fast on fault-tolerant quantum computers in the circuit model. Fault tolerance constrains the choice of available gates, so that arbitrary gates required for a simulation algorithm must be constructed from sequences of fundamental operations. We examine techniques for constructing arbitrary gates which perform substantially faster than circuits based on the conventional Solovay-Kitaev algorithm [C.M. Dawson and M.A. Nielsen, \emph{Quantum Inf. Comput.}, \textbf{6}:81, 2006]. For a given approximation error $ε$, arbitrary single-qubit gates can be produced fault-tolerantly and using a limited set of gates in time which is $O(\log ε)$ or $O(\log \log ε)$; with sufficient parallel preparation of ancillas, constant average depth is possible using a method we call programmable ancilla rotations. Moreover, we construct and analyze efficient implementations of first- and second-quantized simulation algorithms using the fault-tolerant arbitrary gates and other techniques, such as implementing various subroutines in constant time. A specific example we analyze is the ground-state energy calculation for Lithium hydride.

The present paper slightly extends recent results from [C. Bardos, F. Golse, L. Paillard, Comm. Math. Sci., 10 (2012), 159--190] to the case of boundary conditions for the Boltzmann equation more general than Maxwell's accomodation condition.

description: Using archival multi--epoch ACS/WFC images in the F606W and F814W filters of a resolved stellar field in Local Group dwarf elliptical galaxy M32 we have made an accurate Colour-Magnitude Diagram and a careful search for RR Lyr variable stars. We identified 416 bona fide RR Lyr stars over our field of view, and their spatial distribution shows a rising number density towards the centre of M32. These new observations clearly confirm the tentative result of Fiorentino et al. (2010), on a much smaller field of view, associating an ancient population of RR Lyr variables to M32. We associate at least 83 RR Lyr stars in our field to M32. In addition the detection of 4 Anomalous Cepheids with masses in the range 1.2-1.9 Mo indicates the presence of relatively young, 1-4 Gyr old, stars in this field. They are most likely associated to the presence of the blue plume in the Colour-Magnitude Diagram. However these young stars are unlikely to be associated with M32 because the radial distribution of the blue plume does not follow the M32 density profile, and thus they are more likely to belong to the underlying M31 stellar population. Finally the detection of 3 Population II Cepheids in this field gives an independent measurement of the distance modulus in good agreement with that obtained from the RRLyr, mu0=24.33 +- 0.21 mag.

description: We present an experimental study of dynamical back-action cooling of the fundamental vibrational mode of a thin semitransparent membrane placed within a high-finesse optical cavity. We study how the radiation pressure interaction modifies the mechanical response of the vibrational mode, and the experimental results are in agreement with a Langevin equation description of the coupled dynamics. The experiments are carried out in the resolved sideband regime, and we have observed cooling by a factor 350 We have also observed the mechanical frequency shift associated with the quadratic term in the expansion of the cavity mode frequency versus the effective membrane position, which is typically negligible in other cavity optomechanical devices.

description: We set up a multiresolution analysis on fractal sets derived from limit sets of Markov Interval Maps. For this we consider the $\mathbb{Z}$-convolution of a non-atomic measure supported on the limit set of such systems and give a thorough investigation of the space of square integrable functions with respect to this measure. We define an abstract multiresolution analysis, prove the existence of mother wavelets, and then apply these abstract results to Markov Interval Maps. Even though, in our setting the corresponding scaling operators are in general not unitary we are able to give a complete description of the multiresolution analysis in terms of multiwavelets.

description: We analysed some properties of galaxies structures based on PF Catalogue of galaxy structures (Panko & Flin 2006) and Tully NBG Catalog (Tully 1988) At first, we analyzed the orientation of galaxies in the 247 optically selected rich Abell clusters, having in the area considered as cluster at least 100 members. The distribution of the position angles of the galaxy as well as two angles describing the spatial orientation of galaxy plane were tested for isotropy, applying three statistical tests. We found that anisotropy increases with the number of member galaxies, which means there exists the relation between anisotropy and cluster richness. We do not find connection of galaxy alignment and Bautz - Morgan morphological type of parent cluster. The statistically marginal relation between velocity dispersion and cluster richness was observed. However it was found that velocity dispersion decreases with Bautz - Morgan type at almost $3 σ$ level. Separately we analyzed ellipticities for 6188 low redshift ($z < 0.18$) poor and rich galaxy structures which have been examined along with their evolution. Finally we analysed the Binggeli effect. The orientation of galaxy groups in the Local Supercluster (LSC), is strongly correlated with the distribution of neighbouring groups in the scale till about 20 Mpc. During analyses of galaxy structures from PF catalogue the situation was quite different. The efect is observed only for more elongated structures ($e \le 0.3$). The range of the distance in which the effect was observed, was estimated as about $60 h^{-1} MPc$.

description: Ongoing millimeter VLBI observations with the Event Horizon Telescope allow unprecedented study of the innermost portion of black hole accretion flows. Interpreting the observations requires relativistic, time-dependent physical modeling. We discuss the comparison of radiative transfer calculations from general relativistic MHD simulations of Sagittarius A* and M87 with current and future mm-VLBI observations. This comparison allows estimates of the viewing geometry and physical conditions of the Sgr A* accretion flow. The viewing geometry for M87 is already constrained from observations of its large-scale jet, but, unlike Sgr A*, there is no consensus for its millimeter emission geometry or electron population. Despite this uncertainty, as long as the emission region is compact, robust predictions for the size of its jet launching region can be made. For both sources, the black hole shadow may be detected with future observations including ALMA and/or the LMT, which would constitute the first direct evidence for a black hole event horizon.

Tunnelling anisotropic magnetoresistance of Fe/GaAs/Ag(001) junctions from first principles: Effect of hybridized interface resonances
Creators: name: Sykora, Rudolf

Year: 2012
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Results of first-principles calculations of the Fe/GaAs/Ag(001) epitaxial tunnel junctions reveal that hybridization of interface resonances formed at both interfaces can enhance the tunnelling anisotropic magnetoresistance (TAMR) of the systems. This mechanism is manifested by a non-monotonic dependence of the TAMR effect on the thickness of the tunnel barrier, with a maximum for intermediate thicknesses. A detailed scan of k-resolved transmissions over the two-dimensional Brillouin zone proves an interplay between a few hybridization-induced hot spots and a contribution to the tunnelling from the vicinity of the Gamma-bar point. This interpretation is supported by calculated properties of a simple tight-binding model of the junction which reproduce qualitatively most of the features of the first-principles theory.

description: This study while assessing the impact of bank credit on agricultural and manufacturing sectors' outputs in Nigeria focused on the following specific objectives, to: examine the effect of bank credit on the agricultural sector outputs in Nigeria, and investigate the influence of bank credit on manufacturing sector outputs in Nigeria. Ex-post facto research design was adopted to ascertain the cause and effect of the key variables. Two hypotheses were tested using Ordinary Least Square (OLS). The findings showed that the total credit to private sector had a positive and significant effect on agricultural sector outputs; and that total credit to private sector had a positive and significant influence o manufacturing sector outputs. The study recommended that government should ensure that credits were sufficiently allocated to particularly the agricultural and manufacturing sectors in Nigeria and made obtainable at very reasonable lending rates. This will enable the two critical sectors attain production possibilities, thereby accelerating economic growth and development in the long run

description: In this study, we present photometric and spectroscopic variations of the extremely small mass ratio ($q\simeq 0.1$) late-type contact binary system \astrobj{V1191 Cyg}. The parameters for the hot and cooler companions have been determined as $M_\textrm{h}$ = 0.13 (1) $M_{\odot}$, $M_\textrm{c}$ = 1.29 (8) $M_{\odot}$, $R_\textrm{h}$ = 0.52 (15) $R_{\odot}$, $R_\textrm{c}$ = 1.31 (18) $R_{\odot}$, $L_\textrm{h}$ = 0.46 (25) $L_{\odot}$, $L_\textrm{c}$ = 2.71 (80) $L_{\odot}$, the separation of the components is $a$= 2.20(8) $R_{\odot}$ and the distance of the system is estimated as 278(31) pc. Analyses of the times of minima indicates a period increase of $\frac{dP}{dt}=1.3(1)\times 10^{-6}$ days/yr that reveals a very high mass transfer rate of $\frac{dM}{dt}=2.0(4)\times 10^{-7}$$M_{\odot}$/yr from the less massive component to the more massive one. New observations show that the depths of the minima of the light curve have been interchanged.

Subjektivität, Emotionalität und die chinesische ba-Konstruktion
Creators: name: Jing-Schmidt, Zhuo
Publisher: name: CHUN - Chinesischunterricht
Year: 2022

description: This paper is concerned with the concept of discourse dramaticity in terms of subjectivity and emotionality inherent in the use of the Chinese ba-construction as developed by Jing-Schmidt (2005). The author referred to selective attention as the cognitive mechanism underlying the meaning of dramaticity. Based on the psychological principle of negativity bias which is a specific representation of selective attention, the author hypothesized that since language is an integral part of cognition, the use of the ba-construction should reflect this bias if it indeed is a device of construing subjectively and emotionally relevant events. Frequency counts conducted on authentic corpus-based data confirmed that significantly more negative events than positive or neutral events are depicted by using the ba-construction, thus validating the notion of dramaticity including subjectivity and emotionality as central to the semantics and pragmatics of the ba-construction.

description: Glitches in pulsars are likely to trigger oscillation modes in the fluid interior of neutron stars. We examined these oscillations specifically at r-mode frequencies. The excited r-modes will emit gravitational waves and can have long damping time scales O(minutes - days). We use simple estimates of how much energy the glitch might put into the r-mode and assess the detectability of the emitted gravitational waves with future interferometers.
