description: We present the first systematic investigation of the morphological and timing properties of flares in GRBs observed by Swift/XRT. We consider a large sample drawn from all GRBs detected by Swift, INTEGRAL and HETE-2 prior to 2006 Jan 31, which had an XRT follow-up and which showed significant flaring. Our sample of 33 GRBs includes long and short, at low and high redshift, and a total of 69 flares. The strongest flares occur in the early phases, with a clear anti-correlation between the flare peak intensity and the flare time of occurrence. Fitting each X-ray flare with a Gaussian model, we find that the mean ratio of the width and peak time is = 0.13+/-0.10, albeit with a large scatter. Late flares at times > 2000 seconds have long durations, Delta t>300 s, and can be very energetic compared to the underlying continuum. We further investigated if there is a clear link between the number of pulses detected in the prompt phase by BAT and the number of X-ray flares detected by XRT, finding no correlation. However, we find that the distribution of intensity ratios between successive BAT prompt pulses and that between successive XRT flares is the same, an indication of a common origin for gamma-ray pulses and X-ray flares. All evidence indicates that flares are indeed related to the workings of the central engine and, within the standard fireball scenario, originate from internal shocks rather than external shocks. While all flares can be explained by long-lasting engine activity, 29/69 flares may also be explained by refreshed shocks. However, 10 can only be explained by prolonged activity of the central engine.

description: The present study investigates whether exposure to the “Peppa Pig” series can successfully lead two Greek preschoolers to acquire English vocabulary after watching ten episodes in English. Moreover, it measures the receptive vocabulary acquisition by the two preschoolers in English as a foreign language (EFL), during two different types of instruction: Simple exposure to the episodes and exposure in combination with instruction. Finally, the study makes a point of examining what kind of words where more easily identified. A specially designed test measured the number of words that preschoolers had retained receptively at the end of the interventions and the same test was repeated after one month, in order to compare the number of words stored and retained in the long-term memory. The findings showed that a considerable amount of EFL vocabulary had been acquired by the preschoolers through the animated series “Peppa Pig”. They also revealed a significant difference between the two types of instruction, mere exposure and exposure in combination with interventions. The conclusion also highlights the significance of chunks and of words that are similar or related to the corresponding Greek words in EFL vocabulary acquisition

description: The chaotic dynamics of fractional (non-integer) order systems have begun to attract much attention in recent years. In this paper, we study the projective synchronization in two coupled fractional order chaotic oscillators. It is shown that projective synchronization can also exist in coupled fractional order chaotic systems. A simple feedback control method for controlling the scaling factor onto a desired value is also presented.

Program planners’ practical knowledge
Creators: name: Sloane-Seale, Atlanta
Publisher: name: University of British Columbia
Year: 2009

description: The adult education literature offers little analysis and understanding of the practical knowledge of the program planning process planners hold and use. Rather, a comprehensive review of theoretical sources revealed the widespread use of the academic model, informed by Tyler’s rationale, which has yielded a linear model of planning and a technical view of planners. By contrast, the theoretical sources on practical knowledge and on curriculum and teachers’ thinking pointed to the use of an experiential model, informed by Schwab’s theoretical concepts, which has presented planning as deliberative, and planners as creators and possessors of knowledge. The purposes of the study were to: gain an understanding of the kinds of practical knowledge planners in a university continuing education unit find useful and relevant to their decision making in program planning; acquire a greater understanding of the planning process from their perspective; and develop categories for interpreting these understandings. The research was guided by an interpretive perspective and qualitative methods. The study was conducted in two phases. A pilot and a follow up study. In total, a purposive sample of six planners, two males and four females, none of whom had pursued graduate study in adult education, working in the same institution, were interviewed. It was concluded that practical knowledge, which informs planning practice, consists of three kinds of knowledge: declarative, procedural, and conditional which stand in dialectical relationship to one another; and that planning practice requires that planners have and use all three kinds of knowledge. Further, planning is indeterminate and contingent on the context and planners’ knowledge. These planners’ practical knowledge incorporates a framework of concepts, rules and routines or strategies, beliefs, values, principles, and metaphors of practice. This framework has implications for planners’ criteria of valid and reliable knowledge, informal and formal planning strategies, the ideological character of knowledge, and ethics of practice. As well, these planners use a combination of planning approaches which are directly related to the nature of the planning context and their own capabilities. The contextual and problematic nature of planning is made explicit. The study challenges the prevailing assumptions associated with a traditional view of planning.
Axigluon signatures at hadron colliders

description: Axigluons are colored heavy neutral gauge boson that are predicted by some theories. The most important model-independent manifestation of axigluons is the generation of a forward--backward asymmetry in top-antitop quark production at $p\bar{p}$ collisions which originates from the charge asymmetry. We update our previous analysis for the inclusive QCD induced forward--backward asymmetry and define a new observable which is more sensitive to the effect than the forward--backward asymmetry. We find a lower limit of 1.4 TeV at 90% C.L. on the axigluon mass from recent measurements of the asymmetry at Tevatron, and extend the analysis to LHC in suitably selected samples. Like at Tevatron, the charge asymmetry can probe larger values of the axigluon mass than the dijet mass distribution.

Στην έρευνα έλαβαν μέρος 44 παιδιά (19 αγόρια, 25κορίτσια) προσχολικής ηλικίας. Είκοσι ένα (n= 21) από αυτά (9 αγόρια, 12 κορίτσια) (5.68 ± .65 έτη) αποτέλεσαν την ομάδα παρέμβασης, ενώ τα υπόλοιπα είκοσι τρία (n= 23, 10 αγόρια, 13 κορίτσια) (5.46 ± .65 έτη) αποτέλεσαν την ομάδα ελέγχου. Τα παιδιά της ομάδας παρέμβασης παρακολούθησαν ένα πρόγραμμα μουσικοκινητικής αγωγής διάρκειας έξι εβδομάδων, με συχνότητα δύο φορές την εβδομάδα, 45 λεπτά/ μάθημα. Στο ίδιο χρονικό διάστημα, τα παιδιά της ομάδας ελέγχου συμμετείχαν σε παιγνιώδεις δραστηριότητες εστιασμένες στην εκτέλεση βασικών κινητικών δεξιοτήτων. Πριν και μετά την παρέμβαση εφαρμόστηκε ένα τεστ για τη μέτρηση της ρυθμικής ικανότητας (K-rhythm-test, KINVENT, www.k-invent.com) και ένα τεστ για το χρόνο αντίδρασης. Σύμφωνα με τα αποτελέσματα της ανάλυσης διακύμανσης με επαναλαμβανόμενες μετρήσεις (ANOVA), η ομάδα παρέμβασης παρουσίασε στατιστικά σημαντική βελτίωση σε σχέση με την ομάδα ελέγχου στη ρυθμική ικανότητα και το χρόνο αντίδρασης. Το συμπέρασμα της έρευνας αυτής είναι ότι ένα πρόγραμμα μουσικοκινητικής αγωγής συμβάλλει θετικά στη βελτίωση της ρυθμικής ικανότητας και του χρόνου αντίδρασης παιδιών προσχολικής ηλικίας
description: The aim of the present study was the examination of the effects of a music and movement program based on the approaches of Orff and Dalcroze on rhythmic ability and movement time of preschool children. In the study took part 44 preschool children (19 boys, 25 girls). The treatment group consisted of 21 children (9 boys, 12 girls, 5.68 ± .65 years old). The control group consisted of 23 children (10 boys, 13 girls, 5.46 ± .65 years old). The treatment group took part in a music and movement program based on the approaches of Orff and Dalcroze which lasted six weeks. During the same period, the control group participated in a physical education lesson with emphasis on basic movement skills. Prior and after the intervention, the children were assessed in rhythm (K-rhythm-test, www.k-invent.com) and movement time. According to the results of ANOVA with repeated measures the treatment group performed significantly better on the post-test measure, compared to the control group, in both rhythm and movement time. It may be concluded that a music and movement program based on the approaches of Orff and Dalcroze has a positive effect on rhythm ability and movement time of preschool children

description: In this paper we show that the vortex states can be created not only in magnetically soft "small" (with the dipolar and exchange energy competition) cylindrical dots, but also in magnetically saturated "big" (when the exchange is neglected) cylindrical dots. A property associated with a vortex structure becomes evident from an analysis of confinement phenomena of magnetic oscillations in a ferrite disk with a dominating role of magnetic-dipolar (non-exchange-interaction) spectra. In this case the scalar (magnetostatic-potential) wave functions may have a phase singularity in a center of a dot. A non-zero azimuth component of the flow velocity demonstrates the vortex structure. The vortices are guaranteed by the chiral edge states of magnetic-dipolar modes in a quasi-2D ferrite disk.

description: We present a theoretical formalism for scattering of the twisted neutrons by nuclei in a kinematic regime where interference between Coulomb interaction and the strong interaction is essential. Twisted neutrons have definite quantized values of an angular momentum projection along the direction of propagation, and we show that it results in novel observable effects for the scattering cross section, spin asymmetries and polarization of the scattered neutrons. We demonstrate that additional capabilities provided by beam's orbital angular momentum enable new techniques for measuring both real and imaginary parts of the scattering amplitude. Several possible observables are considered, for which the targets may be either well-localized with respect to the spatial beam profile, or the scattering occurs incoherently on nuclei in a bulk target. The developed approach can be applied to other nuclear reactions with strongly interacting twisted particles.

description: Grain alignment theory has reached the stage where quantitative predictions of the degree of alignment and its variations with optical depth are possible. With the goal of studying the effect of clumpiness on the sub-millimeter and far infrared polarization we computed the polarization due to alignment via radiative torques within clumpy models of cores and molecular clouds. Our models were based upon a highly inhomogeneous simulation of compressible magnetohydrodynamic turbulence. The P-I relations for our models reproduce those seen in observations. We show that the degree of polarization observed is extremely sensitive to the upper grain size cut-off, and is less sensitive to changes in the radiative anisotropy. Furthermore, despite a variety of dust temperatures along a single line of sight through our core and amongst dust grains of different sizes, the assumption of isothermality amongst the aligned grains does not introduce a significant error. Our calculations indicate that sub-mm polarization vectors can be reasonably good tracers for the underlying magnetic field structure, even for relatively dense clouds (A_V~10 to the cloud center). The current predictive power of the grain alignment theory should motivate future polarization observations using the next generation of multi-wavelength sub-mm polarimeters such as those proposed for SOFIA.

description: Considering an environment containing polygonal obstacles, we address the problem of planning motions for a pair of planar robots connected to one another via a cable of limited length. Much like prior problems with a single robot connected via a cable to a fixed base, straight line-of-sight visibility plays an important role. The present paper shows how the reduced visibility graph provides a natural discretization and captures the essential topological considerations very effectively for the two robot case as well. Unlike the single robot case, however, the bounded cable length introduces considerations around coordination (or equivalently, when viewed from the point of view of a centralized planner, relative timing) that complicates the matter. Indeed, the paper has to introduce a rather more involved formalization than prior single-robot work in order to establish the core theoretical result -- a theorem permitting the problem to be cast as one of finding paths rather than trajectories. Once affirmed, the planning problem reduces to a straightforward graph search with an elegant representation of the connecting cable, demanding only a few extra ancillary checks that ensure sufficiency of cable to guarantee feasibility of the solution. We describe our implementation of A${}^\star$ search, and report experimental results. Lastly, we prescribe an optimal execution for the solutions provided by the algorithm.

Materials for Fusion energy technology – Improvement of thermal stability of cold-rolled tungsten sheets by potassium-doping
Creators: name: Lied, Philipp
Publisher: name: Karlsruher Institut für Technologie (KIT)
Year: 2020

description: Tungsten is a promising material for high-temperature applications like in future fusion reactors. To overcome the brittle behaviour of conventional tungsten, significant progress has been made in the last decade to improve the ductility of tungsten by severe cold-rolling. The thereby created fine-grained microstructure, however, is not stable at temperatures above 800 °C, leading to a recrystallized, embrittled material. In this talk, I will present parts of our ongoing study, which utilizes potassium-doping to inhibit recrystallization in cold-rolled tungsten sheets at high temperatures. First, the evolution of rolling texture and mechanical properties with increasing rolling strain is compared to equivalently rolled pure tungsten sheets. The second part shows results from isochronal and isothermal annealing experiments, how restoration phenomena can coarsen the tungsten microstructure and the inhibition potential of potassium-bubbles with increasing dispersion.

description: Ο Πατριάρχης των Σέρβων Παύλος Stojčević υπήρξε μια ηγετική φυσιογνωμία της σύγχρονης ιστορίας του Σερβικού Πατριαρχείου. Ο ενάρετος βίος του, η βαθιά και μεστωμένη πνευματικότητά του, η ακτημοσύνη του και η ευαγγελική του κατάρτιση αποτέλεσαν στοιχεία που χαρακτήρισαν τον επίγειο βίο του και ενέπνευσαν την σερβική κοινωνία στο να τον θεωρεί το πρότυπό της. Δεν επέτρεψε την Σερβική Εκκλησία να διολισθήσει σε εθνικισμούς κατά την περίοδο του εμφυλίου πολέμου στην πρώην Γιουγκοσλαβία 1990-1995. Απολαμβάνει και σήμερα ιδιαίτερη αγάπη και τιμή από το σερβικό λαό. Δίκαια θεωρήθηκε ότι αποτέλεσε η περίπτωση του πατριάρχη Παύλου μια αυθεντική κληρονομιά, μια γνήσια μίμηση του Αγίου Σάββα του και πρώτου αρχιεπισκόπου της Σερβικής Εκκλησίας
description: The Patriarch of the Serbs Paul Stojcevic was a leading countenance of the modern history of the Serbian Patriarchate. His virtuous life, his deep and replete spirituality, his indigence and his evangelical education were elements that defined his earthly living and inspired the Serbian community to consider him its model. He did not allow the Serbian Church to elude in acts of nationalism during the civil war in Yugoslavia during 1990-1995. Even today he enjoys special love and honor by the Serbian people. Rightfully the case of Patriarch Paul was considered to have constituted an authentic heritage, a genuine imitation of Saint Savvas, of the first Archbishop of the Serbian Church

description: Two entropic dynamical models are considered. The geometric structure of the statistical manifolds underlying these models is studied. It is found that in both cases, the resulting metric manifolds are negatively curved. Moreover, the geodesics on each manifold are described by hyperbolic trajectories. A detailed analysis based on the Jacobi equation for geodesic spread is used to show that the hyperbolicity of the manifolds leads to chaotic exponential instability. A comparison between the two models leads to a relation among statistical curvature, stability of geodesics and relative entropy-like quantities. Finally, the Jacobi vector field intensity and the entropy-like quantity are suggested as possible indicators of chaoticity in the ED models due to their similarity to the conventional chaos indicators based on the Riemannian geometric approach and the Zurek-Paz criterion of linear entropy growth, respectively.

description: We present radio observations of comet 9P/Tempel 1 associated with the Deep Impact spacecraft collision of 2005 July 4. Weak 18-cm OH emission was detected with the Parkes 64-m telescope, in data averaged over July 4 to 6, at a level of 12 +/- 3 mJy km/s, corresponding to OH production rate 2.8 x 10^{28} molecules/second (Despois et al. inversion model, or 1.0 x 10^{28} /s for the Schleicher & A'Hearn model). We did not detect the HCN 1-0 line with the Mopra 22-m telescope over the period July 2 to 6. The 3 sigma limit of 0.06 K km/s for HCN on July 4 after the impact gives the limit to the HCN production rate of < 1.8 x 10^{25} /s. We did not detect the HCN 1-0 line, 6.7 GHz CH_3OH line or 3.4-mm continuum with the Australia Telescope Compact Array (ATCA) on July 4, giving further limits on any small-scale structure due to an outburst. The 3 sigma limit on HCN emission of 2.5 K km/s from the ATCA around impact corresponds to limit < 4 x 10^{29} HCN molecules released by the impact.

title: Paleomagnetism of the mesozoic lamprophyre dikes in north-central Newfoundland
Creators: name: Prasad, Jagat Nandan
Publisher: name: Memorial University of Newfoundland
Year: 1981

description: A paleomagnetic study of 86 samples from 18 lamprophyre dikes collected from the Notre Dame Bay area in north-central Newfoundland was done to define their age of emplacement. Published K-Ar dates of 144 to 115 m.y. (Late Jurassic to Early Cretaceous) from the dikes place these among the youngest rocks in eastern Canada. Measurements of natural remanence (NRM) give directions closely aligned to the present field at the site. A detailed alternating-field (AF) demagnetization yielded stable directions with optimum vector grouping for 9 dikes at 10-35 mT peak field. Similarly, the thermal treatment showed stability of remanence with tightest grouping at 300°c for 8 dikes and at 500°c for 7 dikes. The overall mean directions corresponding to thermal and AF cleaning are indistinguishable at 95% confidence level, which gives confidence in the stability of remanence obtained from two independent tests. The AF and thermal treatment coupled with thermomagnetic analysis and an isothermal remanence (IRM) study indicate that the stable remanence resides in a single component of magnetite or titanomagnetite. Studies of Rayleigh loops and high-field hysteresis loops suggest that the natural remanence is carried by a mixture of fine-grained single-domain and pseudo-single domain magnetites of stoichiometric to cation-deficient composition. The AF and thermal mean directions correspond to poles 75°N, 168°W (dp, dm = 7.4°, 9.7°) and 72°N, 152°W (dp, dm = 5.2°, 6.6°) respectively, which are in good agreement with each other. Bath pales are of normal polarity, though the present study revealed for the first time the occurrence of a reversed polarity (with well-grouped directions in one dike only) among the Notre Dame Bay lamprophyres. These pole positions are intermediate between the poles reported previously from two other lamprophyre localities in the Notre Dame Bay area, and also are intermediate between the Lower Cretaceous poles and Jurassic poles reported from other parts of the Appalachians. This suggests a good correlation between the age of magnetization and the range of available radiometric dates.

description: We present spectroscopy of a transit of the exoplanet HD 189733b. By modeling the Rossiter-McLaughlin effect (the anomalous Doppler shift due to the partial eclipse of the rotating stellar surface), we find the angle between the sky projections of the stellar spin axis and orbit normal to be lambda = -1.4 +/- 1.1 deg. This is the third case of a ``hot Jupiter'' for which lambda has been measured. In all three cases lambda is small, ruling out random orientations with 99.96% confidence, and suggesting that the inward migration of hot Jupiters generally preserves spin-orbit alignment.

description: The momentum and helicity density distributions of the strange quark sea in the nucleon are obtained in leading order from charged-kaon production in deep-inelastic scattering on the deuteron. The distributions are extracted from spin-averaged K+/- multiplicities, and from K+/- and inclusive double-spin asymmetries for scattering of polarized positrons by a polarized deuterium target. The shape of the momentum distribution is softer than that of the average of the ubar and dbar quarks. In the region of measurement 0.02 < x < 0.6 and Q^2 > 1.0 GeV^2, the helicity distribution is zero within experimental uncertainties.

description: Στόχος αυτής της εργασίας είναι να εξετάσεις τις τεχνικές και τις μεθόδους τις οποίες μπορεί να χρησιμοποιήσει ένας πολιτιστικός οργανισμός με σκοπό να μετατραπεί σε μπράντ. Θεωρούμε πως αυτό είναι ένα αρκετά ενδιαφέρον θέμα, ειδικά για την Ελλάδα λαμβάνοντας υπόψη ότι μεγάλο μέρος της οικονομίας μας βασίζεται στον πολιτισμό. Όσον αφορά τις μεθόδους έρευνας που χρησιμοποιήσαμε, εφαρμόσαμε δύο ποιοτικές μεθόδους και μια ποσοτική μέθοδο έρευνας, μία μελέτη περίπτωσης, συνεντεύξεις ανοιχτής δομής και ερωτηματολόγιο, αντίστοιχα. Πιο συγκεκριμένα, τα στοιχεία που συγκεντρώσαμε προέρχονται χρησιμοποιώντας ως μελέτη περίπτωσης το TEDxThessaloniki και παίρνοντας συνεντεύξεις από ανθρώπου που ασχολούνται με το συγκεκριμένο ιβέντ. Επιπλέον, δημιουργήσαμε ένα ερωτηματολόγιο το οποίο απαντήθηκε από τους εθελοντές του TEDxThessaloniki 2017 έτσι ώστε να έχουμε μια πιο πλήρη εικόνα του οργανισμού. Τα αποτελέσματα που προέκυψαν ήταν αρκετά ενθαρρυντικά καθώς καταφέραμε να αποδείξουμε κυρίως δύο πράγματα. Αφενός αποδείχθηκε πως υπάρχει πολιτιστικό μπράντινγκ και αφετέρου αποδείχθηκε το γεγονός πως υπάρχουν συγκεκριμένοι παράγοντες που βοηθάνε στη δημιουργία αυτού.
description: The purpose of this study is to examine the techniques and the methods that a cultural organization could use in order to become a cultural brand. We think that this is a pretty interesting topic for research, especially in Greece, as our economy is pretty much based in culture. As far as the used methodology is concerned, we applied two qualitative research methods and a quantitative; a case study, semi-formal interviews and a questionnaire respectively. More specifically the data were gathered using TEDxThessaloniki as a case study and interviewing people associated with the specific event. Additionally, we created a questionnaire which was answered by TEDxThessaloniki 2017 volunteers in order to have a more complete aspect of this specific organization. Our findings were pretty encouraging as we proved mainly two things. The first one is that cultural branding exists and the second one is that there are specific factors contributing to it as well.
Light Propagation in a Background Field for Time-Space Noncommutativity and Axionic Noncommutative QED

description: We study the low-energy effects of space-time non-commutativity on light propagation in a background electromagnetic field. Contrary to some of the previous claims, we find no polarization rotation for vanishing time-space commutator $[\hat{x}^i,\hat{x}^0]= 0$, although dispersion relation is modified, allowing for propagation faster than the vacuum speed of light. For non-zero $[\hat{x}^i,\hat{x}^0]$, as allowed with a proper quantization, a naive rotation effect is found to be actually absent when physical fields are defined through Seiberg-Witten map. We also consider non-commutative QED weakly coupled to small mass particles such as axions. Non-commutativity is found to dominate the inverse oscillation length, compared to axion mass and QED effects, for mixing particle masses smaller than $10^{-12} eV$. Conventional constraints on axion coupling based on photon-axion transition rates are unmodified, however induced ellipticity is proportional to the non-commutativity squared length scale. This last effect is found to be too small to account for the ellipticity reported by the PVLAS experiment, yet unexplained by conventional QED or axion physics.

description: The literature features many instances of spacetimes containing two black holes held apart by a thin distribution of matter on the axis joining the holes. For all such spacetimes, the Einstein field equations are integrated with an energy-momentum tensor that does not include a contribution from the axial matter; the presence of this matter is inferred instead from the existence of a conical singularity in the spacetime. And for all such spacetimes, the axial matter is characterized by a pressure (or tension) equal to its linear energy density; the matter is therefore revealed to have a very specific equation of state. Our purpose with this paper is to show that the axial matter can be introduced at the very start of the exercise, through the specification of a distributional energy-momentum tensor, and that one can choose for it any equation of state. To evade no-go theorems regarding line sources in general relativity, we retreat to a perturbative expansion of the gravitational field, using the Schwarzschild metric as a description of the background spacetime. Instead of a second black hole, our prototypical system features a point particle at a fixed position outside the Schwarzschild black hole, attached to a string extending to infinity. This matter is described in terms of a distributional energy-momentum tensor, and we examine different equations of state for the string. To integrate the field equations we introduce a new "Weyl" gauge for the metric perturbation, which allows us to find closed-form expressions for the gravitational potentials. Our solutions are linearized versions of multi-hole spacetimes, and some of them feature strings with a varying tension, unequal to the energy density. We describe the properties of these spacetimes, and begin an exploration of their extended thermodynamics.

description: We prove results on bounded solutions to backward stochastic equations driven by random measures. Those bounded BSDE solutions are then applied to solve different stochastic optimization problems with exponential utility in models where the underlying filtration is noncontinuous. This includes results on portfolio optimization under an additional liability and on dynamic utility indifference valuation and partial hedging in incomplete financial markets which are exposed to risk from unpredictable events. In particular, we characterize the limiting behavior of the utility indifference hedging strategy and of the indifference value process for vanishing risk aversion.

description: COVID-19 (Coronavirus) hit the global society and economy with a big surprise. In particular, work-from-home has become a new norm for employees. Despite the fact that COVID-19 can equally attack innocent people and cybercriminals, it is ironic to see surges in cyberattacks leveraging COVID-19 as a theme, dubbed COVID-19 themed cyberattacks or COVID-19 attacks for short, which represent a new phenomenon that has yet to be systematically understood. In this paper, we make the first step towards fully characterizing the landscape of these attacks, including their sophistication via the Cyber Kill Chain model. We also explore the solution space of defenses against these attacks.

Factors influencing the provision of health education programs for patients during hospitalization

description: Health education has been an essential part of health care for many years. Some acute care hospitals provide health education programs for patients during hospitalization. These programs are offered only in certain patient care areas; therefore, all patients do not have access to this service. The purpose of this study was to identify and describe factors that influence the provision of health education programs for patients during hospitalization on medical surgical patient care areas. Nurses make up approximately 70% of the health care professionals in acute care hospitals; therefore, a nursing perspective on this issue was sought. Using a descriptive, qualitative approach and the PRECEDE model for health promotion planning and evaluation, 14 registered nurses in various positions in an acute care community-based hospital were interviewed. Data from this study were classified as direct or indirect influences on the provision of health education programs for patients. Six main conclusions were drawn: (a) no Type 2 , "planned" health education program was provided for patients during hospitalization, (b) a Type 3, "comprehensive" health education program was provided for specific patients - namely those recovering from a heart attack, (c) the influence of the medical model on the provision of health education programs for patients during hospitalization was significant and pervasive, (d) nurses and other health care professionals were unaware of the impact the medical model had on their approach to health education programs for patients, (e) factors, in addition to time and resources, were identified as important in influencing the provision of health education programs, and (f) more exploration is needed to identify additional factors in the PRECEDE model, in order to understand the phenomenon regarding the provision of health education programs for patients during hospitalization in an acute care facility. Previous studies have fallen short in grasping the basis for the disparity in the provision of health education programs for patients during hospitalization. Therefore, more studies are required in this area to fully understand the factors and challenges involved.

Universal resource-efficient topological measurement-based quantum computation via color-code-based cluster states

description: Topological measurement-based quantum computation (MBQC) enables one to carry out universal fault-tolerant quantum computation via single-qubit Pauli measurements with a family of large entangled states called cluster states as resources. Raussendorf's three-dimensional cluster states (RTCSs) based on the surface codes are mainly considered for topological MBQC. In such schemes, however, the fault-tolerant implementation of the logical Hadamard, phase ($Z^{1/2}$), and $T$ ($Z^{1/4}$) gates which are essential for building up arbitrary logical gates has not been achieved to date without using state distillation, while the controlled-NOT (CNOT) gate does not require it, to best of our knowledge. State distillation generally consumes many ancillary logical qubits, thus it is a severe obstacle against practical quantum computing. To solve this problem, we suggest an MBQC scheme via a family of cluster states called color-code-based cluster states (CCCSs) based on the two-dimensional color codes instead of the surface codes. We define logical qubits, construct elementary logical gates, and describe error correction schemes. We show that all the logical Clifford gates including the CNOT, Hadamard, and phase gates can be implemented fault-tolerantly without state distillation, although the fault-tolerant $T$ gate still requires it. We further prove that the minimal number of physical qubits per logical qubit in a CCCS is at most approximately 1.8 times smaller than the case of an RTCS. We lastly show that the error threshold of MBQC via CCCSs for logical-$Z$ errors is 2.7-2.8%, which is comparable to the value for RTCSs, assuming a simple error model where physical qubits have $X$-measurement or $Z$ errors independently with the same probability.
