description: We present a Gaussian-basis implementation of orbital-free density-functional theory (OF-DFT) in which the trust-region image method (TRIM) is used for optimization. This second-order optimization scheme has been constructed to provide benchmark all-electron results with very tight convergence of the particle number constraint, associated chemical potential and electron density. It is demonstrated that, by preserving the saddle-point nature of the optimization and simultaneously optimizing the density and chemical potential, an order of magnitude reduction in the number of iterations required for convergence is obtained. The approach is compared and contrasted with a new implementation of the nested optimization scheme put forward by Chan, Cohen and Handy. Our implementation allows for semi-local kinetic-energy (and exchange-correlation) functionals to be handled self-consistently in all-electron calculations. The all-electron Gaussian-basis setting for these calculations will enable direct comparison with a wide range of standard high-accuracy quantum-chemical methods as well as with Kohn-Sham density-functional theory. We expect that the present implementation will provide a useful tool for analysing the performance of approximate kinetic-energy functionals in finite systems.

description: The objectives of this study are to monitor and evaluate the Roadway Weather Information System (RWIS). Six RWIS sites have been installed at locations selected by the Kentucky Department of Highways. Each site includes sensors which measure temperature, precipitation, relative humidity, wind speed, pavement temperature, surface condition, and chemical concentration. The data can be accessed remotely using a Windows-based software program. The data are also stored in a central database for future use.  A preliminary reliability study has been completed for five of the sites, and data are being collected for a more extensive reliability assessment. The accuracy of the atmospheric sensors will be determined through a comparison with National Weather Service records. Data are being collected to compare the pavement sensor readings with observed road conditions. The storm logs of chemical usage will be obtained from the Department of Highways to compare with National Weather Service records and the RWIS database. These data will be used to perform a cost-benefit analysis.  The primary use of the RWIS data during the winter of 1997 - 1998 will be to evaluate the system. In the future, the RWIS will supplement existing sources of information used to make decisions about snow and ice control. The data are expected to increase the efficiency of the snow and ice control operations. Other uses for the weather data are also being considered.

description: Ricci flow deformation of cosmological initial data sets in general relativity is a technique for generating families of initial data sets which potentially would allow to interpolate between distinct spacetimes. This idea has been around since the appearance of the Ricci flow on the scene, but it has been difficult to turn it into a sound mathematical procedure. In this expository talk we illustrate, how Perelman's recent results in Ricci flow theory can considerably improve on such a situation. From a physical point of view this analysis can be related to the issue of finding a constant-curvature template spacetime for the inhomogeneous Universe, relevant to the interpretation of observational data and, hence, bears relevance to the dark energy and dark matter debates. These techniques provide control on curvature fluctuations (intrinsic backreaction terms) in their relation to the averaged matter distribution.

description: In this paper, we describe a canopolis (i.e. categorified planar algebra) formalism for Khovanov and Rozansky's link homology theory. We show how this allows us to organize simplifications in the matrix factorizations appearing in their theory. In particular, it will put the equivalence of the original definition of Khovanov-Rozansky homology and the definition using Soergel bimodules in a more general context, allow us to give a new proof of the invariance of triply graded homology and give new analysis of the behavior of triply graded homology under the Reidemeister IIb move.

description: The present project based on the codes of the performance theory, the science that analyzes the phenomena of theatrical action, includes the collection, registration and study of primary material that concerns the local theatrical production with axis the naked body in the theatrical stages of Thessaloniki the last decade (1997-2008). The process of research concerned the collection and registration of performances’ identity that included naked, personal interviews with artists that participated in the above performances (based on a common questionnaire), the elaboration of interviews’ material and the registration of conclusions. The fundamental objective of the thesis constituted the interpretation of naked in the theatrical scene as an integral element of art implicated or not of the socio-political and his moral-economy dimension. The chapters refer upon the use and the symbolism of naked, the difficulties that the naked actor confronted with on the stage, the application of the director‘s vision, the audience‘s approval or disapproval concerning images of naked body, and the configuration of theatrical critique as mediator between the artistic project and the spectator.

description: Experimental and numerical results suggest that the brain can be viewed as a system acting close to a critical point, as confirmed by scale-free distributions of relevant quantities in a variety of different systems and models. Less attention has received the investigation of the temporal correlation functions in brain activity in different, healthy and pathological, conditions. Here we perform this analysis by means of a model with short and long-term plasticity which implements the novel feature of different recovery rates for excitatory and inhibitory neurons, found experimentally. We evidence the important role played by inhibitory neurons in the supercritical state: We detect an unexpected oscillatory behaviour of the correlation decay, whose frequency depends on the fraction of inhibitory neurons and their connectivity degree. This behaviour can be rationalized by the observation that bursts in activity become more frequent and with a smaller amplitude as inhibition becomes more relevant.

The Hole Argument. Physical Events and the Superspace

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

description: The 'hole argument'(the English translation of German 'Lochbetrachtung') was formulated by Albert Einstein in 1913 in his search for a relativistic theory of gravitation. The hole argument was deemed to be based on a trivial error of Einstein, until 1980 when John Stachel (Talk on Einsteins Search for General Covariance, 1912-1915 at the GRG meeting in Jena 1980) recognized its highly non-trivial character. Since then the argument has been intensively discussed by many physicists and philosophers of science. (See e.g., Earman & Norton (1987), Gaul & Rovelli (1999), Stachel & Iftime(2005}, and Iftime & Stachel(2006).) I shall provide here a coordinate-free formulation of the argument using the language of categories and bundles, and generalize the argument for arbitrary covariant and permutable theories (see Iftime & Stachel(2006). In conclusion I shall point out a way of avoiding the hole argument, by looking at the structure of the space of solutions of Einstein's equations on a space-time manifold. This superspace Q(M) is defined as the orbit space of space-time solutions on M under the action of the diffeomorphisms of M, and it plays an important role in the study of the gravitational field and attempts to find a theory of quantum gravity (QG).

Seconded teachers as teacher educators
Creators: name: Badali, Salvador John
Publisher: name: University of British Columbia
Year: 2009

description: This is a study of seconded teachers' experiences as university instructors and faculty advisors in the Faculty of Education at the University of British Columbia. Data were gathered for this study through interviews with 17 seconded teachers (5 first-year seconded teachers, 8 continuing seconded teachers, and 4 teachers who reentered the school system after secondment). The purpose of my study was to understand more clearly the experiences of seconded teachers in the teacher education program through the use of Glaser and Strauss's (1967) grounded theory approach. The results indicated that the seconded teachers in this study moved through stages: seeking the position, preparing for secondment, expressing self doubts and loneliness, adjusting to the tempo and workload, working with adult learners, and looking for support. As university instructors, seconded teachers bring realism to the teacher education program by presenting fundamentals of teaching, by modeling teaching strategies, by connecting theory and practice, and by sharing narratives. Seconded teachers acknowledge with reservations that as evaluators they possess power over student teachers. Regardless of how they might prefer to conceive of their role, in the end, they become evaluators. Seconded teachers displayed various communication styles. Reflection, an aspect of communication, was also identified as important. The themes that have emerged in this study point to 5 general central issues: the contrast between university and school cultures, the strength of reflection on practice, seconded teachers' commitment to classroom teaching, seconded teachers' professional identities, and secondment as professional development. The results of this study suggest that the temporary, short-term nature of secondment, as it now stands, may be a lateral career move rather than a vertical progression. Comments suggest that the Faculty of Education could do a better job of educating seconded teachers about, not only the preservice teacher education program, but specifically the expectations and roles for the seconded participants.

Δεδομένης της πρωτοφανούς φωτεινότητας και του ρυθμού με τον οποίο θα γίνονται οι συγκρούσεις στο LHC, ο όγκος των δεδομένων που λαμβάνεται είναι τεράστιος και θα πρέπει με κάποιο τρόπο να αποθηκευτεί και να αναλυθεί. Για αυτό το λόγο έχουν επιστρατευθεί καινοτόμες υπολογιστικές τεχνολογίες, όπως το Grid.
description: The ATLAS experiment in LHC is a High Energy Physics experiment meant to discover whatever may come up from p-p collisions at the energy of 14 TeV at the centre of mass. Bearing in mind the unprecedented luminosity and event rate at LHC collisions, the data volume to be received is huge and must be stored and analysed in an efficient way. That is the reason why state-of-the-art computing technologies have been adopted, such as Grid. Under such circumstances it becomes clear that the ongoing data acquisition process has to be monitored systematically to assure its quality and therefore the detector's good performance. This thesis describes all these procedures, whereas the code developed concetrates on the monitoring of reconstruction at Tier-0 centre, the heart of Grid, using data coming from the muon spectrometer. First, a detailed description of track reconstruction in the muon spectrometer is provided and then, results are shown demonstrating the performance of the ATLAS detector and software during the ATLAS Commissioning data taking periods. Software development within the Data Quality Monitoring framework is a demanding field. I requires deep understanding of the undergoing computing procedures, the layout and performance of the entire ATLAS experiment, the most complex experiment that has been designed up to this date.

description: The aim of this paper is to establish a complete sample of red supergiants (RSGs) in M31 and M33. The member stars of the two galaxies are selected from the near-infrared (NIR) point sources after removing the foreground dwarfs from their obvious branch in the $J-H/H-K$ diagram with the archival photometric data taken by the UKIRT/WFCAM. This separation by NIR colors of dwarfs from giants is confirmed by the optical/infrared color-color diagrams ($r-z/z-H$ and $B-V/V-R$), and the Gaia measurement of parallax and proper motion. The RSGs are then identified by their outstanding location in the members' $J-K/K$ diagram due to high luminosity and low effective temperature. The resultant sample has 5,498 and 3,055 RSGs in M31 and M33 respectively, which should be complete because the lower limiting $K$ magnitude of RSGs in both cases is brighter than the complete magnitude of the UKIRT photometry. Analysis of the control fields finds that the pollution rate in the RSGs sample is less than 1\%. The by-product is the complete sample of oxygen-rich asymptotic giant branch stars (AGBs), carbon-rich AGBs, thermally pulsing AGBs and extreme AGBs. In addition, the tip-RGB is determined together with its implication on the distance modulus to M31 and M33.

In particular, in asymptotically anti-de Sitter space (adS) stable black hole hair is known to exist for su(2) EYM. We review recent work in which it is shown that stable hair also exists in su(N) EYM for arbitrary N, so that there is no upper limit on how much stable hair a black hole in adS can possess.

The connection between mass loss and nucleosynthesis

Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)

description: I discuss the relationship between mass loss and nucleosynthesis on the Asymptotic Giant Branch (AGB). Because of thermal pulses and possibly other mixing processes, products of nucleosynthesis can be brought to the surface of AGB stars, increasingly so as the star becomes more luminous, cooler, and unstable against pulsation of its tenuous mantle. As a result, mass loss is at its most extreme when dredge-up is too. As the high rate of mass loss truncates AGB evolution, it determines the enrichment of interstellar space with the AGB nucleosynthesis products. The changing composition of the stellar atmosphere also affects the mass-loss process, most obviously in the formation of dust grains - which play an important role in driving the wind of AGB stars.

Long-ranged velocity correlations in dense systems of self-propelled particles

description: Model systems of self-propelled particles reproduce many phenomena observed in laboratory active matter systems that defy our thermal equilibrium-based intuition. In particular, in stationary states of self-propelled systems, it is recognized that velocities of different particles exhibit non-trivial equal-time correlations. Such correlations are absent in equivalent equilibrium systems. Recently, researchers found that the range of the velocity correlations increases with increasing persistence time of the self-propulsion and can extend over many particle diameters. Here we review the initial studies of long-ranged velocity correlations in solid-like systems of self-propelled particles. Then, we demonstrate that the long-ranged velocity correlations are also present in dense fluid-like systems. We show that the range of velocity correlations in dense systems of self-propelled particles is determined by the combination of the self-propulsion and the virial bulk modulus that originates from repulsive interparticle interactions.

description: We report laboratory results of a coronagraphic test bench to assess the intensity reduction differences between a "Gaussian" tapered focal plane coronagraphic mask and a classical hard-edged "Top Hat" function mask at Extreme Adaptive Optics (ExAO) Strehl ratios of ~94%. However, unlike a traditional coronagraph design, we insert a reflective focal plane mask at 45 degree to the optical axis. We also used an intermediate secondary mask ("Mask_2") before a final image in order to block additional mask-edge diffracted light. The test bench simulates the 8.1m Gemini North telescope. It includes one spider vane, different mask radii (r= 1.9, 3.7, 7.4 lambda/D) and two types of reflective focal plane masks (hard-edged "Top Hat" and "Gaussian" tapered profiles). In order to investigate the relative performance of these competing coronagraphic designs with regard to extra-solar planet detection sensitivity, we utilize the simulation of realistic extra-solar planet populations (Nielson et al. 2006). With an appropriate translation of our laboratory results to expected telescope performance, a "Gaussian" tapered mask radius of 3.7 lambda/D with an additional mask ("Mask_2") performs best (highest planet detection sensitivity). For a full survey with this optimal design, the simulation predicts ~30% more planets detected compared to a similar sized "Top Hat" function mask with "Mask_2." Using the best design, the point contrast ratio between the stellar PSF peak and the coronagraphic PSF at 10 lambda/D (0.4" in H band if D = 8.1m) is ~10 times higher than a classical Lyot "Top Hat" coronagraph. Hence, we find a Gaussian apodized mask with an additional blocking mask is a superior (~10x higher contrast) than use of a classical Lyot coronagraph for ExAO-like Strehls.

description: Στην παρούσα εργασία μελετάται η εφαρμογή διαφορετικών μεθόδων δρομολόγησης σε ένα σύστημα grid, το οποίο αποτελείται από δύο ομοιογενή sites. Στόχος της μοντελοποίησης και προσομοίωσης του συστήματος αυτού είναι η μελέτη της αποτελεσματικότητας κάθε μεθόδου δρομολόγησης συναρτήσει του φόρτου εργασίας για την επίτευξη μέγιστης απόδοσης. Κάθε site αποτελείται από δεκαέξι εξυπηρετητές και από έναν τοπικό δρομολογητή (local scheduler). Έχουμε δύο ειδών εργασίες στο σύστημα: τοπικές διεργασίες που εξυπηρετούνται από τα sites και εργασίες grid (gangs) που δρομολογούνται από τον grid scheduler, ο οποίος διαθέτει τη δική του ουρά αναμονής. Οι τοπικές διεργασίες και τα gangs συναγωνίζονται μεταξύ τους για τους ίδιους πόρους του συστήματος. Ωστόσο, οι τοπικές διεργασίες θεωρούνται μεγαλύτερης σπουδαιότητας και είναι σημαντικό ο χρόνος αναμονής τους να είναι όσο το δυνατόν μικρότερος. Σκοπός είναι η μελέτη τριών διαφορετικών πολιτικών δρομολόγησης όσον αφορά τα gangs (από τις οποίες οι δύο υποστηρίζουν μετανάστευση και η μία όχι) και η ανάδειξη της αποδοτικότερης εκ των τριών. Η εργασία χωρίζεται σε δύο μέρη. Στο πρώτο μέρος παρουσιάζεται η έννοια της προσομοίωσης και τα χαρακτηριστικά της (Κεφάλαιο 1), γίνεται μια εισαγωγή στο grid (Κεφάλαιο 2) και αναλύονται τα κύρια σημεία της θεωρίας ουρών (Κεφάλαιο 3). Στο δεύτερο μέρος γίνεται μια περιγραφή του μοντέλου (Κεφάλαιο 4), παρουσιάζεται ο τρόπος υλοποίησης του (Κεφάλαιο 5), πραγματοποιείται μια σειρά πειραμάτων και εξαγωγή συμπερασμάτων (Κεφάλαιο 6).
description: This work studies the application of various scheduling techniques on a grid system consisting of two homogeneous sites. The goal of modelling and simulating this system is to study the efficiency of each scheduling technique as a function of workload, in order to maximize performance. Each site consists of sixteen processors and a local scheduler, while the whole is governed by a grid scheduler that has its own waiting queue. There are two different job types in the system competing for the same resources: local jobs and grid jobs (gangs). The local jobs have priority over the gangs and it is imperative that their waiting time be minimized. Three different gang scheduling approaches are studied (two of which support migration and one that does not) and the most effective of the three is determined. This paper is organised in two parts. The first part introduces the idea of simulation, its importance and its characteristics (Chapter 1), it presents the meanings of grid computing (Chapter 2), and analyzes the main points of queuing theory (Chapter 3). The second part gives a description of the model (Chapter 4), explains the way it has been implemented (chapter 5), and studies the results of a series of experiments (Chapter 6).

description: Estimates of the accretion rate in symbiotic recurrent novae (RNe) often fall short of theoretical expectations by orders of magnitude. This apparent discrepancy can be resolved if the accumulation of mass by the white dwarf (WD) is highly sporadic, and most observations are performed during low states. Here we use a reanalysis of archival data from the Digital Access to a Sky Century @Harvard (DASCH) survey to argue that the most recent nova eruption in symbiotic RN T CrB, in 1946, occurred during -- and was therefore triggered by -- a transient accretion high state. Based on similarities in the optical light curve around 1946 and the time of the prior eruption, in 1866, we suggest that the WD in T CrB accumulates most of the fuel needed to ignite the thermonuclear runaways (TNRs) during accretion high states. A natural origin for such states is dwarf-nova like accretion-disk instabilities, which are expected in the presumably large disks in symbiotic binaries. The timing of the TNRs in symbiotic RNe could thus be set by the stability properties of their accretion disks. T CrB is in the midst of an accretion high state like the ones we posit led to the past two nova eruptions. Combined with the approach of the time at which a TNR would be expected based on the 80-year interval between the prior two novae ($2026 \pm$3), the current accretion high state increases the likelihood of a TNR occurring in T CrB in the next few years.

description: While qualitative research can produce a rich understanding of peoples’ mind, it requires an essential and strenuous data annotation process known as coding. Coding can be repetitive and time-consuming, particularly for large datasets. Crowdsourcing provides flexible access to workers all around the world, however, researchers remain doubtful about its applicability for coding. In this study, we present an interactive coding system to support crowdsourced deductive coding of semi-structured qualitative data. Through an empirical evaluation on Amazon Mechanical Turk, we assess both the quality and the reliability of crowd-support for coding. Our results show that non-expert coders provide reliable results using our system. The crowd reached a substantial agreement of up to 91% with the coding provided by experts. Our results indicate that crowdsourced coding is an applicable strategy for accelerating a strenuous task. Additionally, we present implications of crowdsourcing to reduce biases in the interpretation of qualitative data.

description: We say $x \in \{0,1,2 \}^{\NN}$ is a word with Sturmian erasures if for any $a\in \{0,1,2 \}$ the word obtained erasing all $a$ in $x$ is a Sturmian word. A large family of such words is given coding trajectories of balls in the game of billiards in the cube. We prove that the monoid of morphisms mapping all words with Sturmian erasures to words with Sturmian erasures is not finitely generated.
Medical students’ experiences of teaching and educational advocacy develops their professionalism​

description: ‘Helping others learn’ is a distinctive characteristic of healthcare worker professionalism. Healthcare students typically teach one another, formally (e.g., institutionally-employed tutors) and informally (e.g., education-centred advocacy through leadership/membership of student societies, representation on educational committees). The literature says little about such activities, or their impact on professional identities or careers. 



Since 2019, we have offered optional professional development in teaching (‘Learning to Teach’, LTT) to UNSW final-year Medicine students. Students choosing LTT in 2021 and 2022 were invited to submit structured portfolios detailing their teaching and educational advocacy (TEA) experiences over their six-year undergraduate program. The 61 submitted portfolios were reviewed by two medical education specialists and those students with the most relevant experience supported in applying for conjoint/adjunct medical educator status with the Faculty of Medicine and Health. A smaller group were sponsored for Faculty-funded mentoring to apply for professional recognition as Associate Fellows (AFHEA) assessed directly by Advance HE. 



The portfolios showed students had diverse and extensive experience in TEA activities, and a broad interest in teaching professional development. From the 2021 and 2022 cohorts, 15 final-year students have used their extensive TEA experience for successful conferral applications as conjoint/adjunct faculty after transitioning into their first junior doctor year. Of these affiliates, 9 submitted reflections on their TEA experiences for independent assessment by Advance HE and were awarded international AFHEA recognition. Subsequently, 6 have received institutional recognition (education awards) for developing innovative teaching resources. 



Quality assurance in healthcare education focuses on visible teaching in formal curricula by paid teaching staff. We believe learning and professional benefits are also accruing from students’ informal TEA experiences, and that recognition of such experiences—along with structured professional development in teaching—would enrich healthcare faculties a the world. With our ongoing research into TEA activities, we anticipate global interest around the professional identity and career benefits of supporting healthcare students in teaching development. 

 

The systematic demonstration of students’ TEA activities may assist HPEs to develop learner-centred ‘Student-as-Teacher’ curricula.

description: The aim of craniofacial reconstruction is to produce a likeness of a face from the skull. Few works in computerized assisted facial reconstruction have been done in the past, due to poor machine performances and data availability, and major works are manually reconstructions. In this paper, we present an approach to build 3D statistical models of the skull and the face with soft tissues from the skull of one individual. Results on real data are presented and seem promising.

description: String theory is at the moment the only advanced approach to a unification of all interactions, including gravity. But, in spite of the more than thirty years of its existence, it does not make any empirically testable predictions, and it is completely unknown which physically interpretable principles could form the basis of string theory. At the moment, "string theory" is no theory at all, but rather a labyrinthic structure of mathematical procedures and intuitions. The only motivations for string theory consist in the mutual incompatibility of the standard model of quantum field theory and of general relativity as well as in the metaphysics of the unification program of physics, aimed at a final unified theory of all interactions, including gravity. The article gives a perspective on the problems leading to and resulting from this situation.
