description: We have studied the phi->a_0(980) gamma process with the KLOE detector at the Frascati phi-factory DAPhNE by detecting the phi->eta pi^0 gamma decays in the final states with eta->gamma gamma and eta->pi^+ pi^- pi^0. We have measured the branching ratios for both final states: Br(phi->eta pi^0 gamma)=(7.01 +/- 0.10 +/- 0.20)x10^-5 and (7.12 +/- 0.13 +/- 0.22)x10^-5 respectively. We have also extracted the a_0(980) mass and its couplings to eta pi^0, K^+ K^-, and to the phi meson from the fit of the eta pi^0 invariant mass distributions using different phenomenological models.

description: We study the thermal Casimir effect between two thick slabs composed of plane-parallel layers of random dielectric materials interacting across an intervening homogeneous dielectric. It is found that the effective interaction at long distances is self averaging and its value is given by a that between non-random media with the effective dielectric tensor of the corresponding random media. The behavior at short distances becomes random (sample dependent) and is dominated by the local values of the dielectric constants proximal to each other across the homogeneous slab. These results are extended to the regime of intermediate slab separations by using perturbation theory for weak disorder and also by extensive numerical simulations for a number of systems where the dielectric function has a log-normal distribution.

description: We describe the first three-dimensional simulation of the gravitational collapse of a massive, rotating molecular cloud that includes heating by both non-ionizing and ionizing radiation. We find that as the first protostars gain sufficient mass to ionize the accretion flow, their H II regions are initially gravitationally trapped, but soon begin to rapidly fluctuate between trapped and extended states, in agreement with observations. Over time, the same ultracompact H II region can expand anisotropically, contract again, and take on any of the observed morphological classes. In their extended phases, expanding H II regions drive bipolar neutral outflows characteristic of high-mass star formation. The total lifetime of H II regions is given by the global accretion timescale, rather than their short internal sound-crossing time. The pressure of the hot, ionized gas does not terminate accretion. Instead the final stellar mass is set by fragmentation-induced starvation. Local gravitational instabilities in the accretion flow lead to the build-up of a small cluster of stars, all with relatively high masses due to heating from accretion radiation. These companions subsequently compete with the initial high-mass star for the same common gas reservoir and limit its mass growth. Our findings show that the most significant differences between the formation of low-mass and high-mass stars are all explained as the result of rapid accretion within a dense, gravitationally unstable, ionized flow.

description: The booklet showcases AI4Media's contributions to understanding the impact of artificial intelligence on both society as a whole and individual users. These contributions are essential due to the widespread deployment and growing significance of AI technologies in everyday applications. Generative AI enables the creation of realistic multimedia content that media professionals can use to improve their production pipelines. However, the same technologies can be used by malevolent actors to misinform the public, and automatic detection methods are needed. The focus is on video and audio content because their automatic analysis is particularly challenging. Political news available in classical and social media outlets shapes our understanding of socially impactful and fuels democratic debates. The booklet presents contributions addressing sentiment analysis, fallacy detection, bias quantification, and framing. These methods address multiple European languages and national contexts and enable cross-country comparisons.

description: We present a new efficient method for computing the non-linearity parameters of the higher order correlation functions of local type curvature perturbations in inflation models having a $\cal N$-component scalar field, focusing on the non-Gaussianity generated during the evolution on super-horizon scales. In contrast to the naive expectation that the number of operations necessary to compute the $n$-point functions is proportional to ${\cal N}^n$, it grows only linearly in ${\cal N}$ in our formalism. Hence, our formalism is particularly powerful for the inflation models composed of a multi-component scalar field. Explicit formulas obtained by applying our method are provided for $n=2,3,4$ and 5, which correspond to power-, bi-, tri- and {\it quad}-spectra, respectively. We also discuss how many parameters we need to parameterize the amplitude and the shape of the higher order correlation functions of local type.

Approximation solutions of the wave problems
Creators: name: Wuryatmo, A S
Publisher: name: University Of Tasmania
Year: 2023

description: In the time dependent situations, the partial differential equations the most closely associated with the wave propagation are of hyperbolic type. Their role in the study of non-linear wave propagation is becoming increasingly important; and the knowledge of the properties of their solution is of considerable value when applications to the physical situations are to be made. Non linearity in wave occur in the evolution of discontinuous solutions from initial data propagates along their characteristics. To obtain accuracy in numerical integrations, small intervals and difference formulas are convenient immediately after crossing the characteristic curve. This work is intended to discussed several numerical solutions, for the two dimensional non-linear wave equations. The methods will be used involve successive approximation, characteristics, and finite difference methods.

description: The Pierre Auger Observatory has a unique potential to search for ultra-high energy photons (above ~1 EeV). First experimental limits on photons were obtained during construction of the southern part of the Observatory. Remarkably, already these limits have proven useful to falsify proposals about the origin of cosmic rays, and to perform fundamental physics by constraining Lorentz violation. A final discovery of photons at the upper end of the electromagnetic spectrum is likely to impact various branches of physics and astronomy.

Two different instructional procedures for a multiplication algorithm and their transfer effects to a higher-order algorithm
Creators: name: Hope, John Alfred
Publisher: name: University of British Columbia
Year: 2011

description: This was a study to determine the effects of two instructional procedures for a multiplication algorithm on the ability of elementary school children to extend this algorithm to the solving of computational tasks involving the use of a higher-order algorithm. Each of two groups was given preliminary instruction in solving multiplication problems via the application of the distributive law. After this readiness phase was completed, students were randomly assigned to either a Tl or T2 treatment group. The Tl subjects were taught a rote-type standard multiplication algorithm for determining the solution of 2 x 1 and 3 x 1 products. No explicit instruction was given to indicate the relationships between the two learning tasks, viz. the acquisition of the distributive law and the standard multiplication algorithm. Unlike the Tl instructional sequence, the T2 instructional sequence was designed to promote the learning of the relationships between the series of learning tasks. That is, the T2 subjects were taught a standard multiplication algorithm that required the explicit use of the distributive law and other acquired algebraic skills. It was hypothesised that this continual integration of learning tasks would enable the T2 subjects to exhibit superiority over the Tl subjects in extending their standard multiplication algorithm to computational tasks requiring the use of an untaught higher-order algorithm. A total of 238 subjects and 8 teachers were used in all phases of the experiment. A mixed model of analysis of variance was used to validate the performance hypothesis. It was found that the Tl subjects were significantly better than the T2 subjects in the performance of the standard multiplication algorithm. An analysis of covariance was performed to determine the validity of the transfer hypothesis. A subject's score on the performance test was used as a covariate in order to equate the disparate computational abilities of the Tl and T2 subjects. Although the mean score of the T2 subjects was higher than that of the Tl subjects on the transfer test, this difference was not statistically significant.

Application of 3D stereophotogrammetry for characterising dynamic association football kick launch parameters and flight trajectories

description: Engineering of Sport 15 - Proceedings from the 15th International Conference on the Engineering of Sport (ISEA 2024)
In association football, ball launch parameters when kicked (velocity and spin vectors and magnitudes), fundamentally influence flight path and kick outcomes. Factors influencing launch parameters include player technique, ball properties, boot characteristics and environmental conditions. For decades, equipment manufacturers have sought to iterate ball and boot designs to promote competitiviely favourable launch parameters for players. Mechancal quantification of these parameters, and the influence of equipment interventions, has proven challenging. Human kinematic and outdoor environment inconsistencies challenge field assessment of such parameters, and many commercially available measurement systems (such as Vicon, radar guns and Trackman) are limited either by caputure speed, spin axis tracking capabilities, measurement accuracy, or by non three dimensional caputure. However, 3D stereophotogrammetry, using a GOM Aramis system, applied with a high-speed video camera pair, has been utilised in golf ball tracking, with excellent accuracy and demonstrable benefits over other commercially available systems. This study attempts to apply GOM Aramis 3D digital image correlation techniques, in a controlled laboratory environment, to capture dynamic launch parameters, and compare differences between independent variables such as ball, boot and environmental conditions, which are hypothesized to influence launch characteristics.  
The perceptions of Fiji primary school teachers in using classroom based student assessment procedures
Creators: name: Tikoduadua, M
Publisher: name: University Of Tasmania
Year: 2023

description: This research has as its theoretical framework the notion of the teacher as an agent for change in schools. The research is based on a study of 137 practising primary teachers (75% female) recruited across the Fiji primary school Years of 1 to 8. The investigation used survey methodology in the Republic of the Fiji Islands. It examined the teachers‚ÄövÑvº perceptions associated with assessment practices since the abolishing of the formal primary school exanimations in 2009 and the transition to more Class Based Assessment (CBA) practices. In this model, assessment and learning are considered linked in three different but related ways. These are: assessment of learning (i.e., tests and examinations of the students); assessment for learning (i.e., feedback to the teacher to design appropriate program for the students involved); and assessment as learning (students reflect on what they are learning and how). On average, teachers in this study agreed that CBA had helped them to be more innovative and creative in their teaching. The indications, are that teachers who brought examples of their students‚ÄövÑvº work along to moderation and assessment meetings to share and discuss their teaching and students‚ÄövÑvº learning, gained more from those meetings and were more confident about their ability to design CBA assessment tasks. The participating teachers reported that CBA had enabled them to be better able to report to the parents of the children they were teaching about what was occurring in the classroom in terms of their students‚ÄövÑvº learning and the classroom program of study. There were no significant gender or years of experience effects in the data, with only one question demonstrating some school Year differentiation. Teachers in Years 6 to 8 reported some advantage in the end of Year 8 formal examinations, compared to teachers in the middle and lower primary school Years. The findings are discussed with reference to the need to reliably link classroom programing and classroom assessment and for the Fiji teachers to receive more professional development about different forms of assessment and measurement techniques, as well as more opportunities to share and discuss assessment issues between themselves. In this research the teachers identified the advantages of CBA, but how it was being implemented and interpreted in Fiji was a concern, with too great a focus on a set number of assessment items. The primary school teachers were looking for more leadership and professional in-service to facilitate a version of CBA that would be more manageable and focussed more on formative as well as summative assessment. The findings are, however, supportive of the use of CBA assessment practices in Fiji primary schools with little real evidence that teachers wanted to return to the formal examinations of the past.
The absorption-dominated model for the X-ray spectra of type I active galaxies: MCG-6-30-15

description: MCG-6-30-15 is the archetypal example of a type I active galaxy showing broad "red-wing" emission in its X-ray spectrum at energies below the 6.4 keV Fe K-alpha emission line and a continuum excess above 20 keV. Miller et al. (2008) showed that these spectral features could be caused by clumpy absorbing material, but Reynolds et al. (2009) have argued that the observed Fe K-alpha line luminosity is inconsistent with this explanation unless the global covering factor of the absorber(s) is very low. However, the Reynolds et al. calculation effectively considers the only source of opacity to be the Fe K bound-free transition and neglects the opacity at the line energy: correction to realistic opacity decreases the predicted line flux by a large factor. We also discuss the interpretation of the covering factor and the possible effect of occultation by the accretion disk. Finally, we consider a model for MCG-6-30-15 dominated by clumpy absorption, which is consistent with global covering factor 0.45, although models that include the effects of Compton scattering are required to reach a full understanding. Variations in covering fraction may dominate the observed X-ray spectral variability.

The study of two successive military coups in Burma and Peru.
Creators: name: Langenbacher, Wolfgang
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this thesis is to study the dynamics of two successive military coups in Burma and Peru. Both of these nations have had a military coup, which was subsequently, after a relatively short period of civilian rule, followed by another coup. All four of these coups have had some impact on the civil bureaucracy, yet in both cases the impact after the second coup was much more pervasive. The question that the thesis is concerned with answering is why did the impact on the bureaucracy change as it did the second time around. The answer lies in the military's dissatisfaction with the civil bureaucracy after the 2nd coups. This dissatisfaction resulted from the following three factors: (1) changes in the goals and purposes of the second coups; (2) changes in military personnel between the first and second coups; (3) experiences of military between coups. (a) Both of the first two coups were carried out for restricted goals and purposes. Consequently, the military had little opportunity or need to extensively concern itself with the civilian bureaucracy. For their less ambitious goals the bureaucracy was quite suitable. The second time around, both military coups occurred under quite different circumstances and for different goals and purposes. Contrary to the static orientation of the first coups, the second ones were carried out for the purpose of moving the nation to a more progressive condition and due to the inability of civilian groups to achieve this goal. The civil bureaucracy had serious weaknesses which did not allow it to meet the military's governing needs and the military carried out extensive actions to rectify this. (b) Younger and more radical officers tended to displace the older and more conservative officers in the second coup, whereas the latter dominated the first coup in both countries. These younger officers more rural and of different social origins from the older officers, tended to be much more hostile to the urban middle civil servants. (c) Some experiences between the coups exacerbated the officers' hostility toward the bureaucracy. That is, in one case betrayal by civil servants of military's programs initiated during the first coup, in the other case having to step into an administrative void in rural areas which the military attributed to a weak and inefficient civil service.

In the case that $A$ is a finitely generated noetherian domain of GK dimension 3 over the complex numbers, we show that the centralizer of an element a $A$ that is not algebraic over the extended centre of $A$ satisfies a polynomial identity.

The resulting Day of Archaeology project archive demonstrates the wide variety of work the archaeological profession undertakes day-to-day across the globe, and helps to raise public awareness of the relevance and importance of archaeology to the modern world.
The first ever Day of Archaeology was held in 2011 and, since then, the project had thousands of archaeologists take part in the event, from those working in the field through to specialists working in laboratories and behind computers. The last Day of Archaeology was on Friday 28th July 2017.

Understanding the H2/HI Ratio in Galaxies

description: We revisit the mass ratio Rmol between molecular hydrogen (H2) and atomic hydrogen (HI) in different galaxies from a phenomenological and theoretical viewpoint. First, the local H2-mass function (MF) is estimated from the local CO-luminosity function (LF) of the FCRAO Extragalactic CO-Survey, adopting a variable CO-to-H2 conversion fitted to nearby observations. This implies an average H2-density Omega_H2=(6.9+-2.7) 10^5/h and Omega_H2/Omega_HI=0.26+-0.11 in the local Universe. Second, we investigate the correlations between Rmol and global galaxy properties in a sample of 245 local galaxies. Based on these correlations we introduce four phenomenological models for Rmol, which we apply to estimate H2-masses for each HI-galaxy in the HIPASS catalogue. The resulting H2-MFs (one for each model for Rmol) are compared to the reference H2-MF derived from the CO-LF, thus allowing us to determine the Bayesian evidence of each model and to identify a clear best model, in which, for spiral galaxies, Rmol negatively correlates with both galaxy Hubble type and total gas mass. Third, we derive a theoretical model for Rmol for regular galaxies based on an expression for their axially symmetric pressure profile dictating the degree of molecularization. This model is quantitatively similar to the best phenomenological one at redshift z=0, and hence represents a consistent generalization while providing a physical explanation for the dependence of Rmol on global galaxy properties. Applying the best phenomenological model for Rmol to the HIPASS sample, we derive the first integral cold gas-MF (HI+H2+helium) of the local Universe.

Extrasolar planet population synthesis II: Statistical comparison with observation

description: This is the second paper in a series of papers showing the results of extrasolar planet population synthesis calculations. In the companion paper (Paper I), we have presented in detail our methods. By applying an observational detection bias for radial velocity surveys, we identify the potentially detectable synthetic planets. The properties of these planets are compared in quantitative statistical tests with the properties of a carefully selected sub-population of actual exoplanets. We use a two dimensional Kolmogorov-Smirnov test to compare the mass-distance distributions of synthetic and observed planets, as well as 1D KS tests to compare the mass, the semimajor axis and the [Fe/H] distributions. We find that some models can account to a reasonable degree of significance for the observed properties. We concurrently account for many other observed features, e.g. the "metallicity effect". This gives us confidence that our model captures several essential features of giant planet formation. Our simulations allow us also to extract the properties of the underlying exoplanet population that are not yet detectable. For example, we have derived the planetary initial mass function (PIMF) and have been led to conclude that the planets detected so far represent only the tip of the iceberg. The PIMF can also be used to predict how the detectable extrasolar planet population will change as the precision of radial velocity surveys improves to an extreme precision of 0.1 m/s.

description: The Shape invariant method has the algebraic structure and its algebras are infinite-dimensional. These algebras are converted into finite-dimensional under conditions. Based on the property of this method we obtain the algebraic structure of some physical potentials in the s-wave Klein-Gordon equation with scalar and vector potential which satisfy the Shape invariant condition.

Effect of boot shape on performance and perception of football movements

Football boots are an important interface between a player and a playing surface. Whilst much research addresses the outsole and stud-surface interaction, boots must also support interactions between a player’s foot, insole, and upper, to ensure performance and comfort. Foot morphology comprises inter- and intra-individual variation; sex and ethnicity are key factors of this. Thus, for mass-produced boots, foot morphology variation can lead to a suboptimal fit and discomfort; 76% of footballers experience discomfort around the heel region alone. The understanding of boot shape on the performance and perception of football movement is limited. This study assessed the effect of boot shape for individuals with wide feet on the performance and perception of football movement tasks.
