The translation of programming languages through the use of a graph transformation language
Creators: name: Van Den Bosch, Peter Nico
Publisher: name: University of British Columbia
Year: 2010

description: It is shown that the automated translation of programming languages suffers from its traditional domination by context free parsing techniques, specifically in failing to deal uniformly with such translation-related concerns as language extension, optimization, error handling and reporting, and multi-stage translation, as well as in generally ad hoc treatment of the context sensitive aspects of translation, particularly those concerned with the identification of symbols. A descriptive technique for discussing translation that takes into account not only the immense and continued success of the syntactic basis for programming language translation but also the need to deal uniformly with the above concerns is presented, and demonstrated to be implementable as a programming tool. This demonstration is effected both by means of a detailed discussion of the technique's application to the expression of translation algorithms, and by a consideration of the practical aspects of its implementation as a programming language. The technique involves a representation of the complete syntactic structure of programs as a directed graph, and the expression of translations as local transformations of the graph representation. A wide range of translation concerns is discussed with reference to graph transformation. Practical experience with an experimental version of a graph transformation language is presented, and used as the basis for a further development in the design. An evaluation of the completed research, and an assessment of its position within concurrent developments in the discipline of programming language translation, conclude this dissertation.

description: In this paper, we study the possibility of building a model of the oscillating universe with quintom matter in the framework of 4-dimensional Friedmann-Robertson-Walker background. Taking the two-scalar-field quintom model as an example, we find in the model parameter space there are five different types of solutions which correspond to: (I) a cyclic universe with the minimal and maximal values of the scale factor remaining the same in every cycle, (II) an oscillating universe with its minimal and maximal values of the scale factor increasing cycle by cycle, (III) an oscillating universe with its minimal and maximal values of the scale factor decreasing cycle by cycle, (IV) an oscillating universe with its scale factor always increasing, and (V) an oscillating universe with its scale factor always decreasing.

description: Tunneling two level systems affect damping, noise and decoherence in a wide range of devices, including nanoelectromechanical resonators, optomechanical systems, and qubits. Theoretically this interaction is usually described within the tunneling state model. The dimensions of such devices are often small compared to the relevant phonon wavelengths at low temperatures, and extensions of the theoretical description to reduced dimensions have been proposed, but lack conclusive experimental verification. We have measured the intrinsic damping and the frequency shift in magnetomotively driven aluminum nanoelectromechanical resonators of various sizes at millikelvin temperatures. We find good agreement of the experimental results with a model where the tunneling two level systems couple to flexural phonons that are restricted to one or two dimensions by geometry of the device. This model can thus be used as an aid when optimizing the geometrical parameters of devices affected by tunneling two level systems.

Τα ερευνητικά ερωτήματα που τέθηκαν προς διερεύνηση αφορούν ειδικότερα στις αντιλήψεις των εκπαιδευτικών για τον ρόλο του σχολείου και των ίδιων στην παρέμβαση σε περιστατικά ενδοοικογενειακής κακοποίησης ανηλίκων, για τις προκλήσεις που αντιμετωπίζουν σε αυτό το ζήτημα, καθώς για τις ανάγκες τους για υποστήριξη στην προστασία ανηλίκων. Το δείγμα αποτελείται από 10 εκπαιδευτικούς δημοτικής εκπαίδευσης. Η συλλογή των δεδομένων έγινε με τη χρήση ατομικών, ημιδομημένων συνεντεύξεων, ενώ τα δεδομένα που προέκυψαν αναλύθηκαν με την μέθοδο της θεματικής ανάλυσης. Από την ανάλυση αναδύθηκαν πέντε βασικά θέματα: το σχολείο ως πλαίσιο για την αποκάλυψη της κακοποίησης, οι πολλαπλοί ρόλοι των εκπαιδευτικών, οι προκλήσεις στην παρέμβαση, η εγκατάλειψη των εκπαιδευτικών και οι ανάγκες των εκπαιδευτικών. Από τα ευρήματα της έρευνας, αναδείχθηκε η φωνή των εκπαιδευτικών σχετικά με τις δυνατότητες που δίνονται στο σχολικό πλαίσιο όσον αφορά την παρέμβαση για την αντιμετώπιση του φαινομένου της ενδοοικογενειακής κακοποίησης ανηλίκων, αλλά και ζητήματα που περιορίζουν την δράση των εκπαιδευτικών. Τα ευρήματα θα μπορούσαν να καθοδηγήσουν τον σχεδιασμό παρεμβάσεων επιμόρφωσης και στήριξης των εκπαιδευτικών στο ζήτημα της παιδικής προστασίας, καθώς και τη διαμόρφωση μιας ολιστικής πολιτικής στην εκπαίδευση σχετικά με το ζήτημα της παιδικής κακοποίησης.
description: The current research focuses on the role of primary education teachers in managing incidents of domestic violence against minors. The research questions investigated the teachers' perceptions of their role in school interventions against domestic child abuse, the challenges they face in this matter, and their needs for support in protecting minors. The sample consisted of 10 primary education teachers. Data collection was carried out using individual, semi-structured interviews, and the data obtained were analyzed using thematic analysis. Five main themes emerged from the analysis: the school as a context for revealing abuse, the multiple roles of teachers, the challenges in intervention, the teachers’ loneliness, and the needs of teachers. The findings highlighted the teachers' perspective regarding the opportunities provided in the school context for addressing the phenomenon of domestic child abuse, as well as issues that limit the teachers’ potential to intervene. The findings could guide the design of training and support programs for teachers on the issue of child protection, as well as the development of a holistic policy in education regarding the issue of child abuse.

description: We describe the concept and experimental demonstration of primary thermometry based on a four probe measurement of a single tunnel junction embedded within four arrays of junctions. We show that in this configuration random sample specific and environment-related errors can be avoided. This method relates temperature directly to Boltzmann constant, which will form the basis of the definition of temperature and realization of official temperature scales in the future.
How the transnational education industry informs international student migration and impacts international student experience on western post-secondary campuses
Creators: Megan McCaskill
Publisher: name: University of Alberta Library
Year: 2023

Since the post-World War II era, the circular migration of western curricula to the developing world and the reverse migration of international students to western post-secondary institutions has created a pipeline allowing for the increase of international students on western campuses. As the number of international students increase, their student experience is minimised to one of expected assimilation, while in reality, international students face a wealth of challenges that impact their ability to succeed. This paper will provide a foundation that places responsibility on post-secondary institutions to provide additional support to their international students and a series of recommendations as to how this could be achieved.

Hyper-accreting tori of Gamma Ray Bursters

description: We present numerical simulations of axisymmetric magnetised massive tori around rotating black holes taking into account the energy losses due to emission of neutrinos. A realistic equation of state is used which takes into account the energy losses due to dissociation of nuclei. The heating due to neutrino-antineutrino annihilation is not included. We study the cases of optically thick, semi-transparent, and optically thin to neutrino discs. We show that neutrino cooling does not change significantly the structure of accretion flow and the total energy release. The time scale of accretion is set by the torus angular momentum. Due to the lack of magnetic dynamo in our calculations, it is the initial strength of magnetic field and its topology that determine the process of jet formation and its energetics. Extrapolation of our results gives the total energy released in the jet $\sim 10^{52}$ erg. This is sufficient to explain the hypernovae explosions associated with GRB 980425 and GRB 030329.

New CP phase of $B_s-\bar B_s$ mixing on ${\rm T}$ violation in $B_{d(s)}\to K^*(ϕ) \ell^{+} \ell^{-}$

description: A large CP-violating phase uncovered recently by CDF and D$Ø$ collaborations in the time-dependent CP asymmetry (CPA) of the $B_s\to J/Ψϕ$ decay clearly indicates that a non-Cabibbo-Kobayashi-Maskawa (CKM) phase has to be brought into the $b\to s$ transition. We find that the model with $SU(2)_L$ singlet exotic quarks can not only provide the new phase induced from the Z-mediated flavor changing neutral current (FCNC) at tree level, but also strongly relate the $B_s-\bar B_s$ mixing, $B_q\to V_q \ell^{+} \ell^{-}$ ($V_{d[s]}=K^*[ϕ])$ and $B_s\to μ^{+} μ^{-}$ together. In particular, we show that the new CP phase can be unambiguously exposed by the large statistical significances of $T$ violating observables in $B_q\to V_q \ell^{+} \ell^{-}$, while the branching ratio of $B_s\to μ^{+} μ^{-}$ can be enhanced to be $O(10^{-8})$.

A tipping point for open citation data

description: Open citation data can improve the transparency and robustness of scientific portfolio analysis, improve science policy decision-making, stimulate downstream commercial activity, and increase the discoverability of scientific articles. Once sparsely populated, public-domain citation databases crossed a threshold of one billion citations in February 2021, during the COVID-19 pandemic. Shortly thereafter, the threshold of one billion public-domain citations from the Crossref database alone. Since the relative advantage of withholding data in closed databases has diminished with the flood of public-domain data, this likely constitutes an irreversible change in the citation data ecosystem. The successes of this movement can guide future open data efforts.

description: The thermodynamic properties of electron gas under the extreme conditions of high temperature, high matter density, and/or a strong magnetic field largely determine the behaviour of matter in upper layers of neutron stars and accretion columns of magnetized neutron stars in binary systems. A strong magnetic field in these objects makes the motion of electrons across the field essentially quantum. The possible electron degeneracy and relativism of electrons are also important. When studying accretion onto a magnetar in a binary system, the intensive generation of electron-positron pairs in the quantizing magnetic field should also be taken into account. We consider in detail the thermodynamic properties of a gas of free electrons in strong magnetic fields, taking into account their relativism and degeneracy, as well as the equilibrium creation of electron-positron pairs in a high-temperature plasma in the presence of a quantizing magnetic field.

description: The short-range correlations are considered for a two-dimensional hard-core boson model on square lattice within Bethe approximation for the clusters consisting of two and four sites. Explicit equations are derived for the critical temperatures of charge and superfluid ordering and their solutions are considered for various ratios of the charge-charge correlation parameter to the transfer integral. It is shown that taking into account short-range correlations for the temperatures of charge ordering results in the appearance of the critical concentration of bosons, which restricts the existence domain of the solutions of charge ordering type. In the case of superfluid ordering with the assumption of short-range correlations, the critical temperature is reduced up to zero values at half-filling. A phase diagram of the hard-core boson model is constructed with the assumption of phase separation within Maxwell's construction and it is shown that taking into account short-range correlations within Bethe approximation quantitatively approximates the form of phase diagram to the results of the quantum Monte Carlo method.

description: We unveil the nature of the structural disorder in bottom-up zigzag graphene nanoribbons along with its effect on the magnetism and electronic transport on the basis of scanning probe microscopies and first-principles calculations. We find that edge-missing m-xylene units emerging during the cyclodehydrogenation step of the on-surface synthesis are the most common point defects. These "bite'' defects act as spin-1 paramagnetic centers, severely disrupt the conductance spectrum around the band extrema, and give rise to spin-polarized charge transport. We further show that the electronic conductance across graphene nanoribbons is more sensitive to "bite" defects forming at the zigzag edges than at the armchair ones. Our work establishes a comprehensive understanding of the low-energy electronic properties of disordered bottom-up graphene nanoribbons.
Tetra-maximal Neutrino Mixing and Its Implications on Neutrino Oscillations and Collider Signatures

description: We propose a novel neutrino mixing pattern in terms of only two small integers 1 and 2 together with their square roots and the imaginary number $i$. This ansatz is referred to as the "tetra-maximal" mixing because it can be expressed as a product of four rotation matrices, whose mixing angles are all π/4 in the complex plane. It predicts θ_{12} = \arctan(2-\sqrt{2}) \approx 30.4^\circ, θ_{13} = \arcsin[(\sqrt{2}-1)/(2\sqrt{2})] \approx 8.4^\circ, θ_{23} = 45^\circ and δ=90^\circ in the standard parametrization, and the Jarlskog invariant of leptonic CP violation is found to be {\cal J} = 1/32. These results are compatible with current data and can soon be tested in a variety of neutrino oscillation experiments. Implications of the tetra-maximal neutrino mixing on the decays of doubly-charged Higgs bosons H^{\pm\pm} -> l^\pm_αl^\pm_β(for α, β= e, μ, τ) are also discussed in the triplet seesaw mechanism at the TeV scale, which will be explored at the upcoming LHC.

description: Thoracic endovascular aortic repair (TEVAR) has become the standard treatment of a variety of aortic pathologies. The objective of this study is to evaluate the hemodynamic effects of stent-graft introducer sheath during TEVAR. Three idealized representative diseased aortas of aortic aneurysm, coarctation of the aorta, and aortic dissection were designed. Computational fluid dynamics studies were performed in the above idealized aortic geometries. An introducer sheath routinely used in the clinic was virtually-delivered into diseased aortas. Comparative analysis was carried out to evaluate the hemodynamic effects of the introducer sheath. Results show that the blood flow to the supra-aortic branches would increase above 9% due to the obstruction of the introducer sheath. The region exposed to high endothelial cell activation potential (ECAP) expands in the scenarios of coarctation of the aorta and aortic dissection, which indicates that the probability of thrombus formation may increase during TEVAR. The pressure magnitude in peak systole shows an obvious rise and a similar phenomenon is not observed in early diastole. The blood viscosity in the aortic arch and descending aorta is remarkably altered by the introducer sheath. The uneven viscosity distribution confirms the necessity of using non-Newtonian models and high viscosity region with high ECAP further promotes thrombosis. Our results highlight the hemodynamic effects of stent-graft introducer sheath during TEVAR, which may associate with perioperative complications.

description: A superconducting microstrip half-wavelength resonator is proposed as a suitable band-pass filter for broadband moderate spectral resolution spectroscopy for terahertz (THz) astronomy. The proposed filter geometry has a free spectral range of an octave of bandwidth without introducing spurious resonances, reaches a high coupling efficiency in the pass-band and shows very high rejection in the stop-band to minimize reflections and cross-talk with other filters. A spectrally sparse prototype filter-bank in the band 300-400 GHz has been developed employing these filters as well as an equivalent circuit model to anticipate systematic errors. The fabricated chip has been characterized in terms of frequency response, reporting an average peak coupling efficiency of 27% with an average spectral resolution of 940.

description: Tightest known quadruple systems VW LMi consists of contact eclipsing binary with P_12 = 0.477551 days and detached binary with P_34 = 7.93063 days revolving in rather tight, 355.0-days orbit. This paper presents new photometric and spectroscopic observations yielding 69 times of minima and 36 disentangled radial velocities for the component stars. All available radial velocities and minima times are combined to better characterize the orbits and to derive absolute parameters of components. The total mass of the quadruple system was estimated at 4.56 M_sun. The detached, non-eclipsing binary with orbital period P = 7.93 days is found to show apsidal motion with U approximately 80 years. Precession period in this binary, caused by the gravitational perturbation of the contact binary, is estimated to be about 120 years. The wide mutual orbit and orbit of the non-eclipsing pair are found to be close to coplanarity, preventing any changes of the inclination angle of the non-eclipsing orbit and excluding occurrence of the second system of eclipses in future. Possibilities of astrometric solution and direct resolving of the wide, mutual orbit are discussed. Nearby star, HD95606, was found to form loose binary with quadruple system VW LMi.

description: The activity ratio of female mice related to rank for each of the four replications of the experiment with females. These are the data underlying figure 4b. Dots on the left-hand side designate activity ratio under group housing conditions, dots on the right-hand side designate activity ratio under single housing conditions. Coloured lines connect the two dots (group housing and single housing) for each dominance rank. The colour of the line designates dominance rank, ranging from red (highest ranking) via orange, yellow, green and blue to purple (least dominant). Because of missing activity values due to equipment malfunction, not all lines are present in all subfigures.

description: This article describes a randomized controlled trial to evaluate the effectiveness of a supervised online delivery of self-help plus (SH+), during the second wave of COVID-19 contagions in Northern Italy. The SH+ is a psychological intervention developed by the World Health Organization to increase a person's ability to deal with stress. In this trial, it was tested primarily as a tool to reduce anxiety and post-traumatic symptomatology in workers of residential nursing and care homes. In order to partial out non-specific effects of the intervention, the SH+ was compared to an equally supervised and structured alternative activity. Secondarily, in view of future emergencies, the potential of SH+ as a tool to reduce perceived stress, increase subjective well-being and foster individual resilience was explored. At post-intervention, the preregistered analysis revealed no difference in self-reported anxiety and/or post-traumatic symptomatology between the group receiving the SH+ and the group engaged in an alternative activity. Some specific and positive effects of the SH+ intervention were only found on self-reported intervention effectiveness and engagement in exploratory analyses. These findings raise the question whether the previously documented effectiveness of the SH+ on self-reported symptomatology and on the prevention of psychiatric conditions could be attributed mostly to non-specific rather than specific factors connected with participant enrolment in a psychological intervention. Indeed, the effects of the SH+ had been previously compared only to the effects of not being engaged in any alternative activity (often described in the literature as ‘treatment as usual’—or ‘enhanced treatment as usual’, when some relevant information is given to the control group as a one-off). Given the negative findings of this study, before the SH+ is implemented in clinical practice, further studies should be conducted to examine its short- and long-term beneficial effects, by means of randomized studies that employ alternative but similarly structured interventions as control conditions, aiming to minimize the confounding effect of non-specific factors.

description: This review summarizes the results of over 100 research papers on the use of adsorbents of different classes and grades (77 adsorbents) for removing different classes of dyes (21 acid, 15 direct, 13 reactive, and 12 basic) under batch conditions. Based on the common classifications of adsorbents in the literature, high-grade adsorbents were collected from the following classes: synthetic adsorbents (27), nanoadsorbents (25), and non-conventional adsorbents (25). In this review, the results of high-grade adsorbents were analysed, i.e. Grade I (Qmax >1000 mg/g) and Grade II (Qmax 500–1000 mg/g) only. Based on the collected results, a guide was developed to select the most efficient adsorbents to be further applied for dyes uptake on a large scale. Four significant criteria: grade of adsorbent, recycling of adsorbent, separation method from solution, and production/recycling costs were essentially considered. Based on the guide, activated carbon and β-cyclodextrin were the most efficient, while magnetic-chitosan was the best among nanomaterials. Regarding non-conventional adsorbents, cellulose was the best and compost was among the most promising materials in the future.

description: Availability of pertinent and detailed information for damaged ancient objects is vital for successful restorative, damage limitation intervention processes in archeology. Visual inspection and radiography testing (RT) constitute widely used non-destructive methods for conservators of such objects. Unfortunately, the quality of RT images is susceptible to blurring caused by the superimposed scattered X-rays. In this study, the no-black-pixel constraint (NBPC) algorithm on its own as well as in the form of an algorithm with the planar-scene assumption (NBPC + PA) was applied to RT images with a view to suppressing image blurring and enhancement of imaging contrast. The results of this study have shown, both qualitatively and quantitatively that the NBPC + PA and NBPC algorithms provide higher imaging contrast for identification and evaluation of damage in corroded ancient metallic relics than using unprocessed RT images alone. Contrast enhancement of up to about 120% and 78% was achieved in comparison with the original image by applying the NBPC+PA and NBPC algorithms, respectively. Practical application and effectiveness of using the processed images were evaluated by expert operators in the area and it was found that using the reconstructed images scored higher (on average by 88%) than the original RT images (on average by 73%) with the NBPC+PA scoring higher (on average by 91%) than the NBPC algorithm (on average by 85%). The operators have found utilizing the processed images leads to better inspection and evaluation of the object enabling better targeted informed for restorative intervention, damage limitation, and maintenance of such objects.
X-ray Dust Scattering at Small Angles: The Complete Halo around GX13+1

description: The exquisite angular resolution available with Chandra should allow precision measurements of faint diffuse emission surrounding bright sources, such as the X-ray scattering halos created by interstellar dust. However, the ACIS CCDs suffer from pileup when observing bright sources, and this creates difficulties when trying to extract the scattered halo near the source. The initial study of the X-ray halo around GX13+1 using only the ACIS-I detector done by Smith, Edgar & Shafer (2002) suffered from a lack of sensitivity within 50'' of the source, limiting what conclusions could be drawn. To address this problem, observations of GX13+1 were obtained with the Chandra HRC-I and simultaneously with the RXTE PCA. Combined with the existing ACIS-I data, this allowed measurements of the X-ray halo between 2-1000''. After considering a range of dust models, each assumed to be smoothly distributed with or without a dense cloud along the line of sight, the results show that there is no evidence in this data for a dense cloud near the source, as suggested by Xiang et al. (2005). Finally, although no model leads to formally acceptable results, the Weingartner & Draine (2001) and nearly all of the composite grain models from Zubko, Dwek & Arendt (2004) give poor fits.

description: BACKGROUND: We investigated the acceptability and feasibility of a new brief intervention for maternal prenatal anxiety within maternity services in London and Exeter, UK. METHODS: One hundred fourteen pregnant individuals attending their 12-week scan at a prenatal clinic with elevated symptoms of anxiety (GAD-7 score of ≥7) were randomly assigned to either the ACORN intervention + Treatment as usual (TAU) (n = 57) or to usual care only (n = 57). The ACORN intervention consisted of 3 2-h group sessions, led by a midwife and psychological therapist, for pregnant individuals and their partners. The intervention included psychoeducation about anxiety, strategies for problem-sovling and tolerating uncertainty during pregnancy, including communicating about these with others, and mindfulness exercises. RESULTS: Engagement rates with ACORN met or exceeded those in primary care services in England. In the intervention arm, 77% (n = 44) of participants attended at least one session, 51% (n = 29) were adherent, defined as attending two or more sessions. Feedback was positive, and participants in the ACORN treatment group demonstrated evidence of a larger drop in their levels of anxiety than the participants in the TAU-only group (Cohen's d = 0.42). CONCLUSION: The ACORN intervention was acceptable to pregnant individuals and their partners and resulted in reductions in anxiety. With further evaluation in a larger-scale trial with child outcomes, there is significant potential for large scale public health benefit.

description: The GHASP survey (Gassendi HAlpha survey of SPirals) consists of 3D Ha data cubes for 203 spiral and irregular galaxies, covering a large range in morphological types and absolute magnitudes, for kinematics analysis. It is the largest sample of Fabry-Perot data published up to now. In order to provide an homogenous sample, reduced and analyzed using the same procedure, we present in this paper the new reduction and analysis for a set of 97 galaxies already published in previous papers but now using the new data reduction procedure adopted for the whole sample. The GHASP survey is now achieved and the whole sample is reduced using adaptive binning techniques based on Voronoi tessellations. We have derived Ha data cubes from which are computed Ha maps, radial velocity fields as well as residual velocity fields, position-velocity diagrams, rotation curves and kinematical parameters for almost all galaxies. The rotation curves, the kinematical parameters and their uncertainties are computed homogeneously using the new method based on the power spectrum of the residual velocity field. This paper provides the kinematical parameters for the whole sample. For the first time, the integrated Ha profiles have been computed and are presented for the whole sample. The total Ha fluxes deduced from these profiles have been used in order to provide a flux calibration for the 203 GHASP galaxies. This paper confirms the conclusions already drawn from half the sample concerning (i) the increased accuracy of position angles measurements using kinematical data, (ii) the difficulty to have robust determinations of both morphological and kinematical inclinations in particular for low inclination galaxies and (iii) the very good agreement between the Tully-Fisher relationship derived from our data and previous determinations.

description: In this communication we introduce a new model which represents the interaction between an atom and two fields injected simultaneously within a cavity including the nonlinear couplers. By using the canonical transformation the model can be regarded as a generalization of several well-known models. We calculate and discuss entanglement between the tripartite system of one atom and the two cavity modes. For a short interaction time, similarities between the behavior based on our solution compared with the other simulation based on a numerical linear algebra solution of the original Hamiltonian with truncated Fock bases for each mode, is shown. For a specific value of the Kerr-like medium defined in this letter, we find that the entanglement, as measured by concurrence, may terminate abruptly in a finite time.
