description: Gamma-ray bursts (GRBs) have long been considered as candidates of ultrahigh-energy cosmic rays (UHECRs). We investigate the signatures of CR proton acceleration in the GRBs by consistently taking into account their hadronic and electromagnetic interactions. We discuss the implications of our findings for high-energy gamma ray observations with the recently launched Fermi Gamma-ray Space Telescope.

description: For Kohn variational calculations on low energy positron hydrogen molecule elastic scattering, we prove that the phase shift approximation obtained using the complex Kohn method is precisely equal to a value which can be obtained immediately via the real-generalized Kohn method. Our treatment is sufficiently general to be applied directly to arbitrary potential scattering or single open channel scattering problems, with exchange if required. In the course of our analysis, we develop a framework formally to describe the anomalous behaviour of our generalized Kohn calculations in the regions of the well known Schwartz singularities. This framework also explains the mathematical origin of the anomaly-free singularities we reported in a previous article. Moreover, we demonstrate a novelty, that explicit solutions of the Kohn equations are not required in order to calculate optimal phase shift approximations. We relate our rigorous framework to earlier descriptions of the Kohn-type methods.

Photons at PHENIX

description: Direct photons are a powerful probe to study the properties of the unique matter created in ultrarelativistic heavy-ion collisions. They carry information on the various stages of a heavy-ion collision. At different transverse momenta (pT), different production processes dominate the direct photon yield in heavy-ion collisions. Photons at high pT can be used to study initial hard scattering processes while photons at low and intermediate pT provide direct information on the hot and dense medium created in such collisions since they origin predominantly from jet-medium interactions and from thermal radiation from the medium itself. PHENIX has measured direct-photon yields over a broad pT and energy range in different collision systems such as Au+Au and Cu+Cu, allowing systematic studies of the behavior of direct photons in heavy-ion collisions. Two different methods have been used to measure the direct photons. An excess of direct photons in Au+Au collisions at low pT beyond the expectation from p+p collisions was measured for the first time via internal conversion. Furthermore, the azimuthal anisotropy parameter v2 has been measured. The direct photon v2 sheds light on the different processes contributing to the production of direct photons. The p+p data at the same energy provide a baseline for understanding the heavy-ion data, but are also interesting in their own right, e.g. for testing pQCD calculations or - as RHIC collides polarized protons - for constraining models on the gluon contribution to the proton spin.

Subjects: M-STO/04 Storia contemporanea

description: Sorto alla fine degli anni ottanta del Novecento, il teatro di narrazione ha raggiunto un notevole successo di pubblico a partire dagli anni Novanta. I suoi legami con il giornalismo d'inchiesta hanno condotto questo genere teatrale verso la narrazione di alcuni tra gli eventi pi controversi della storia dell'Italia repubblicana; eventi non ancora risolti sul piano processuale o al centro di una memoria storica fortemente divisa. Marco Baliani, Marco Paolini e Ascanio Celestini sono i tre autori che abbiamo scelto per affrontare un'analisi delle loro narrazioni in merito, rispettivamente, all'omicidio di Aldo Moro, alla strage di Ustica e all'eccidio delle Fosse Ardeatine. Oggetto della ricerca  l'analisi dell'utilizzo delle fonti da dichiarate o comunque utilizzate dai narratori per la costruzione delle loro performances  la loro selezione, la loro interpretazione e la loro disposizione nel testo e la messa in evidenza del problema della verità e del suo rapporto con il verosimile nelle narrazioni teatrali di eventi storici. Particolare attenzione viene inoltre posta al grande dibattito internazionale tra storia e fiction, alle strategie di coinvolgimento dell'opinione pubblica su temi morali e politici nonché all'analisi dei fattori economici e delle committenze che sono alla base di tali narrazioni.
description: In the eighties of the twentieth century a particular theatrical form appeared in Italy, which is known today as teatro di narrazione (storytelling theater). The storytelling theater has among its best actors and writers those involved in telling contemporary history in order to revive the memory of past events. Marco Baliani, Marco Paolini and Ascanio Celestini are among the actors who now better represent this artistic movement. The purpose of this thesis is to show how their performances are created and spread and to analyze the relationship between historical sources and drama texts of three events in the history of Italy: Mr Aldo Moro's murder, the slaughter of the Fosse Ardeatine and the massacre of Ustica. Particular attention is devoted to the international debate between history and fiction, to the analysis of the relationship between narrators and the public opinion, between morality and politics, and to the study of patronage and economic factors of these performances.

The development and application of a methodology for program evaluation
Creators: name: Gleadow, Norman E.
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to develop a practical methodology of program evaluation from considerations of what the evaluative act required on logical grounds. The methodology developed was based on P.W. Taylor's (1961) analytical treatment of evaluation and M. Scriven's extensive writings on the subject. The study involved two broad phases. The first phase was a discussion of Taylor's and Scriven's thoughts on evaluation showing where they are compatible and overlap. The second phase showed how the ideas developed in the first phase were operationalized and adapted to the evaluation of a teacher training program at the University of British Columbia. A general conclusion of this study was that Taylor's analysis of the method and product of evaluation provided a suitable framework for the evaluation of an educational program. More specifically when Taylor's analysis was combined with Scriven's extensive work, a feasible model of evaluation resulted which readily produced a defensible, overall estimation of worth for an educational product. Although the methodology of evaluation developed in this study was only applied to a teacher training program, it could easily be extended to the evaluation of other educational programs or products.

Search for sterile neutrino mixing in the MINOS long-baseline experiment
Creators: name: The MINOS Collaboration
Publisher: name: arXiv
Year: 2010
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: A search for depletion of the combined flux of active neutrino species over a 735 km baseline is reported using neutral-current interaction data recorded by the MINOS detectors in the NuMI neutrino beam. Such a depletion is not expected according to conventional interpretations of neutrino oscillation data involving the three known neutrino flavors. A depletion would be a signature of oscillations or decay to postulated non-interacting "sterile" neutrinos, scenarios not ruled out by existing data. From an exposure of 3.18x10^{20} protons on target in which neutrinos of energies between ~500 MeV and 120 GeV are produced predominantly as nu_mu, the visible energy spectrum of candidate neutral-current reactions in the MINOS far detector is reconstructed. Comparison of this spectrum to that inferred from a similarly selected near detector sample shows that of the portion of the nu_mu flux observed to disappear in charged-current interaction data, the fraction that could be converting to a sterile state is less than 52% at 90% confidence level (C.L.). The hypothesis that active neutrinos mix with a single sterile neutrino via oscillations is tested by fitting the data to various models. In the particular four-neutrino models considered, the mixing angles theta_{24} and theta_{34} are constrained to be less than 11 degrees and 56 degrees at 90% C.L., respectively. The possibility that active neutrinos may decay to sterile neutrinos is also investigated. Pure neutrino decay without oscillations is ruled out at 5.4 standard deviations. For the scenario in which active neutrinos decay into sterile states concurrently with neutrino oscillations, a lower limit is established for the neutrino decay lifetime tau_3/m_3 > 2.1x10^{-12} s/eV at 90% C.L..

description: We present a method to measure cosmic magnetic fields with ultra high energy cosmic rays (UHECRs). We apply an advanced autocorrelation method to simulated UHECRs which includes their directional as well as energy information. Without explicit knowledge of the UHECR sources, such measurements are sensitive to the number of sources and to the magnetic field strength subjected to the UHECRs. Using a UHECR Monte Carlo model including sources, random walk propagation and a coherent deflection, we explain the procedure of reconstructing the allowed phase space of the model parameters from a simulated autocorrelation measurement.

Elastic and plastic deformation of graphene, silicene, and boron nitride honeycomb nanoribbons under uniaxial tension: A first-principles density-functional theory study

description: This study of elastic and plastic deformation of graphene, silicene, and boron nitride (BN) honeycomb nanoribbons under uniaxial tension determines their elastic constants and reveals interesting features. In the course of stretching in the elastic range, the electronic and magnetic properties can be strongly modified. In particular, it is shown that the band gap of a specific armchair nanoribbon is closed under strain and highest valance and lowest conduction bands are linearized. This way, the massless Dirac fermion behavior can be attained even in a semiconducting nanoribbon. Under plastic deformation, the honeycomb structure changes irreversibly and offers a number of new structures and functionalities. Cagelike structures, even suspended atomic chains can be derived between two honeycomb flakes. Present work elaborates on the recent experiments [C. Jin, H. Lan, L. Peng, K. Suenaga, and S. Iijima, Phys. Rev. Lett. 102, 205501 (2009)] deriving carbon chains from graphene. Furthermore, the similar formations of atomic chains from BN and Si nanoribbons are predicted.

Connecting the very large and the very small: effective particle mass in curved-space cosmological models
Creators: name: Phillips, Peter R.
Publisher: name: arXiv
Year: 2009
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We investigate the propagation of electromagnetic fields and potentials in the plasma of the early Universe, assuming a Friedmann-Robertson-Walker background with negative curvature. Taking over results from classical plasma physics, we show that charged particles will acquire an effective mass that has not only the expected thermal component but also a non-thermal component due to the influence of distant matter. Although this is a direct effect of the vector potential, we show the theory is nevertheless gauge invariant. This phenomenon is therefore in the same category as the Aharonov-Bohm effect. The non-thermal component becomes increasingly important with time, and in some cosmological models can prove to be of decisive importance in bringing about the phase transition that generates normal masses.
title: Legitimacy dynamics of accounting standards setting: the case of Indonesia
Creators: name: Maulana, Aviandi Okta
Publisher: name: University of Reading
Year: 2019

description: “The continuing acceptance of accounting standard setting is a matter of managing legitimacy of the process of standard-setting in addition to, or perhaps, independently of, the technical characteristics of those standards” (Richardson and Eberlein, 2011, p.217) Legitimacy is imperative for any organisational existence, particularly for any standardssetter as accounting standards are inherently subjective. They are neither right or wrong but generally agreed upon. Therefore, legitimacy is a prerequisite for acceptance in accounting standards rule-making. This research builds upon the works of Suchman (1995) on legitimacy to explore and compare legitimacy dynamics between conventional and Islamic accounting standards, particularly in cognitive biases embedded in accounting professional expertise and in religious beliefs in the development of accounting standards. The reason for adopting Suchman’s (1995) work on legitimacy is his emphasis on the co-existence and inter-dependence of the evaluative and cognitive aspects of legitimation. Indonesia is selected as case study due to its unique accounting standards infrastructure, with the existence of dual and parallel standards setter for conventional and Islamic accounting standards development subordinated by the Indonesia Institute of Chartered Accountants (IAI), namely the Financial Accounting Standards Board (DSAK) and the Sharia Accounting Standards Board (DSAS). Conducting 34 semi-structure interviews and utilising thematic analysis, this research identifies three inter-linked bases for legitimacy, all of which are drawn from the interviewees’ perceptions: i) the historical factors including the political and legal context; ii) due process and procedure; and iii) biases embedded in accounting profession and in religious beliefs. This research contends that cognitive biases based on religious considerations are stronger than biases based on professional considerations, that is beliefs based on divine laws and the trust to Islamic actors are stronger than the trust to accounting profession in accounting standards development.

description: Quantum state reconstruction involves measurement devices that are usually described by idealized models, but not known in full detail in experiments. For weak propagating microwaves, the detection process requires linear amplifiers which obscure the signal with random noise. Here, we introduce a theory which nevertheless allows one to use these devices for measuring all quadrature moments of propagating quantum microwaves based on cross-correlations from a dual-path amplification setup. Simultaneously, the detector noise properties are determined, allowing for tomography. We demonstrate the feasibility of our novel concept by proof-of-principle experiments with classical mixtures of weak coherent microwaves.

description: NetSyn was tested on the β-keto acid cleavage enzymes family (BKACE). This family, initially called DUF849 (Domain of Unknown Function) in the PFAM database, was extensively characterized using high-throughput enzymatic screening (Bastard et al., 2014). The profiles of activity issued from the enzymatic screening of 124 representatives on 20 substrates showed a high correlation with the profiles of active sites. Indeed, the 725 proteins of the BKACE family were divided into 7 main groups based on structural classification of active sites by the Active Sites Modeling and Clustering (ASMC) method (de Melo-Minardi et al., 2010). As ASMC groups show a good match with in vitro enzymatic activities, our aim here is to verify NetSyn clustering can identify the ASMC groups, and thus check if NetSyn can cluster iso-functional enzymes.

description: Within the framework of the kinetic energy driven superconductivity, the electromagnetic response in cuprate superconductors is studied in the linear response approach. The kernel of the response function is evaluated and employed to calculate the local magnetic field profile, the magnetic field penetration depth, and the superfluid density, based on the specular reflection model for a purely transverse vector potential. It is shown that the low temperature magnetic field profile follows an exponential decay at the surface, while the magnetic field penetration depth depends linearly on temperature, except for the strong deviation from the linear characteristics at extremely low temperatures. The superfluid density is found to decrease linearly with decreasing doping concentration in the underdoped regime. The problem of gauge invariance is addressed and an approximation for the dressed current vertex, which does not violate local charge conservation is proposed and discussed.

title: Towards a systems model of healthcare: a prototype decision support simulation using model based systems engineering and thematic analysis
Creators: name: McEvoy, Neil Michael
Publisher: name: University of Reading
Year: 2019

description: This dissertation describes the development and assessment of a new model for the analysis and design of healthcare systems. Motivated by a need to better address the challenges still facing the provision of adequate healthcare services, it offers a model that can explain how healthcare functions as a whole system, and supports predicting the outcomes of policy interventions. Determining what model would satisfy the requirements of such a system is decomposed as (i) a design question asking how to construct the model,(ii) a theoretic question asking how healthcare functions as a system, and (iii) an evaluative question asking how well the implemented model answers the first two. Support in the literature is found in (i) existing models, in both healthcare and broader areas of economics; (ii) model theory providing clarity on representation of explanation and prediction; (iii) systems science providing constructs, a taxonomy and a dedicated language with which to describe healthcare systemically; (iv) a broad corpus of publications in the healthcare literature providing a data set of qualitative and theoretical observations for content analysis. The methodology applies Model Based Systems Engineering to the construction of a model, using a template adapted from model theory. Three versions of the model are developed to satisfy theoretic, systemic and epistemic requirements respectively. The results are reported as three related versions of a core representation of healthcare as a system; as a system composed of three familiar global systems: (i) the LifeCourse system captures how people live lives in which their health status is occasionally impaired by illness for which they may receive treatment to offset that impairment; (ii) the Provision Network, in which individuals and organizations with clinical skills and resources collectively and separately provide treatments needed in the population; (iii) in the Payment Exchange, where funds are exchanged to compensate those providers for the services they provide. Assessed against the original criteria, that the model represent healthcare as a dynamic causal system, the systems model that emerges satisfies the requirements of a scientific model. Boundary conditions qualify the scope of each evaluation. The prototype simulation comparing the model’s predicted outputs under three scenarios to historical trends of selected indicators observed in the healthcare system of the Netherlands is qualitatively comparable to the findings reported in the literature. This research extends healthcare knowledge, provides a reproducible methodology and creates an exploratory instrument to conduct simulated experiments in healthcare economics and health policy. Incorporation of boundary conditions points the way to future enhancements aimed at reducing those limitations and expanding the predictive capabilities of the model.

description: We apply the concept of subset seeds proposed in [1] to similarity search in protein sequences. The main question studied is the design of efficient seed alphabets to construct seeds with optimal sensitivity/selectivity trade-offs. We propose several different design methods and use them to construct several alphabets.We then perform an analysis of seeds built over those alphabet and compare them with the standard Blastp seeding method [2,3], as well as with the family of vector seeds proposed in [4]. While the formalism of subset seed is less expressive (but less costly to implement) than the accumulative principle used in Blastp and vector seeds, our seeds show a similar or even better performance than Blastp on Bernoulli models of proteins compatible with the common BLOSUM62 matrix.
Design criteria for the acoustical environment in open plan offices
Creators: name: Matić, Vojislava
Publisher: name: University of British Columbia
Year: 2010

description: The concept of open planned office space is becoming more and more popular. However, there is a serious problem associated with this concept, that being the attainment of speech privacy. Since speech privacy is a very important issue for some types of office work the main objective of this thesis is to study the acoustic requirements of the open plan office. In order to improve office working conditions, it was decided to correlate existing theoretical findings on general office noise and screen/ceiling acoustical performance with actual situations from seven office layout samples taken in the Vancouver, B.C., area. Of the people who have been doing research in this specific area, Geiger and Hamme in Ann Arbor, Michigan, appear to be the furthest advanced. The purpose of this thesis is to extend the work of Geiger and Hamme as a contribution to the existing findings of the acoustical characteristics of open plan office space. To achieve the goals of this thesis, the historical background of office buildings, a study of current space requirements and the importance of speech privacy are examined. Further theoretical issues include an explanation of acoustical performance of specific building elements. The objective of this discussion is to expand the data base of a number of acoustical parameters including average sound levels, articulation index and screen/ceiling attenuation values, in order to further develop existing acoustical design criteria. The study concludes that while there is indeed a need for speech privacy in open plan offices, the degree of need varies considerably with the level of confidentiality. The research confirms that the greater the need for speech privacy, the less satisfactory is the open office concept. Further study in this field is clearly indicated and includes further exploration of the following factors: 1. The definition of people's concerns regarding speech privacy. 2. The economic factors and their implications. 3. The establishment of environmental maxims.

description: We calculate the finite size scaling of the sample-to-sample fluctuations of the free energy $ΔF$ of the $m$ component vector spin glass in the large-$m$ limit. This is accomplished using a variant of the interpolating Hamiltonian technique which is used to establish a connection between the free energy fluctuations and bond chaos. The calculation of bond chaos then shows that the scaling of the free energy fluctuaions with system size $N$ is $ΔF \sim N^μ$ with ${1/5}\leqμ

description: This thesis is a study of the properties of thin GaAs films grown on molybdenum substrates by the close spaced vapour transport (CSVT) deposition technique with the intention that the GaAs/Mo structure would be used as the semiconductor and substrate for economic solar cells. The GaAs films were polycrystalline cubic crystals with no preferred orientation. The crystallite area increased with the temperature at which the substrate was held during growth and at 710°C grain sizes of 100 μm² were observed. The crystallites formed a columnar-like structure with crystal size comparable to the film thickness. No impurities of foreign instrus-ions existed in the films in quantities observable on the electron micro-probe. The resistivity of the GaAs films was 220 Ω cm, hence acceptable for thin film solar cells, however, the GaAs/Mo contact was mildly rectifying. Diodes were fabricated by the deposition of Au onto the GaAs films and the resulting barriers showed values of barrier height of approximately 0.8 eV, ideality factor n = 1.5 to 2, and depletion-layer majority carrier concentration of roughly 10¹⁶ cm⁻³ as measured by J-V and C-V methods. The GaAs films show promise for use in solar cells provided that the Mo/GaAs interface resistance can be reduced.

description: Tetracycline (TC), a common antibiotic used to study bacterial illnesses in living organisms, is also exceedingly dangerous to the aquatic environment. Numerous traditional techniques are applied to remove the TC antibiotics from the water solution. However, these procedures have not helped to get rid of TC antibiotics. So, in this work, photocatalytic TC degradation has been considered. Hydrothermal synthesis was used to create the CoFe2O4/MWCNTs nano-composite, and various techniques were used to characterise it. The characterisation experiments revealed that multi-walled carbon nanotubes (MWCNTs) are successfully incorporated into cobalt ferrite spinel (CoFe2O4) nanoparticles and this limits the rate at which charge carriers recombine after combining with MWCNTs. The effectiveness of the catalyst was then evaluated in a batch reactor using the weight percentage variation of the nano-composite, specifically TC 0.5, TC 01, TC 02, TC 03, and TC 04, with constant pH 7, with TC concentration of 0.05 g/L and nano-composite dosage of 0.6 g/L for 120 min under 120 W/m2 of visible light. The same operational settings were used to study the TC degradation using CoFe2O4 and MWCNTs as individual pure materials. According to the findings, using CoFe2O4/MWCNTs with a weight percentage ratio of 1:4 (TC 04) increased the photocatalytic degradation efficiency to 90.00% compared to pure materials. After being utilised three times in a row, the photocatalysts were as-produced, and it was discovered that there was an approximate 2.7% decrease in removal efficiency. As a result of its comparatively straightforward synthesis, high stability, and high potential for recycling, CoFe2O4/MWCNTs nano-composite, specifically, TC 04, demonstrated a respectable efficiency in the TC degradation. Therefore, this material will make it possible to eliminate and degrade pharmaceutical organic contaminants.

description: We argue that in a second order quantum phase transition driven by an inhomogeneous quench density of quasiparticle excitations is suppressed when velocity at which a critical point propagates across a system falls below a threshold velocity equal to the Kibble-Zurek correlation length times the energy gap at freeze-out divided by $\hbar$. This general prediction is supported by an analytic solution in the quantum Ising chain. Our results suggest, in particular, that adiabatic quantum computers can be made more adiabatic when operated in an "inhomogeneous" way.

description: Cadmium and other heavy metals in landfills pose significant health and environmental risks due to their leaching potential into soil and groundwater when in contact with water or moisture. In this study, we synthesised two composites, composite I (C(I)) and composite II (C(II)), using Algerian clay and coconut shell-derived activated carbon. These composites are intended for controlled landfill waste management. The components are mixed at varying mass percentages, effectively adsorbing cadmium (Cd2+) from aqueous solutions. We conducted a parametric adsorption study using an experimental design. Cd2+ removal is more effective with composite C(II), reaching a Qmax of 163 mg.g−1 and an improved R of 59% at 25°C, while C(I) achieves a Qmax of 131 mg.g−1 and an R of 47%. The pH study indicated significant adsorption in the pH range [6–8]. The experiment utilised a screening design to optimise Cd2+ adsorption and establish the response surface. The coded variable Xi ranged from −1 (low) to + 1 (high) such as pH (X1: 2–6), temperature (X2: 25–45°C), composite mass (X3: 0.5–2.5 g.L−1), stirring speed (X4: 20–180 Oscillation/min), equilibrium time (X5: 60–120 min), and initial solution concentration (X6: 25–225 mg.L−1). The optimal values for X1, X4, and X6 were found to be 6, 180 Oscillation/min, and 185 mg.L−1, respectively.

description: This study investigates the potential of calcium silicates (CS) synthesised from granite and marble waste as an adsorbent for sustainable waste management. A simple and chemical-free synthesis method was adopted in the preparation of CS. X-ray diffraction, scanning electron microscopy, zeta potential and particle size distribution techniques were used for the characterisation of CS. As Pb(II) and its derivatives from various industrial effluents exercise significant negative impact on the environment and human health, an attempt was made to remove Pb(II) by adsorption process. Batch experiments were conducted to evaluate the feasibility of removal of pb(II) using CS. The zeta potential value of −83.7 mV and the mean particle size of 916 nm for the prepared CS can enhance adsorption process. The analysis of various adsorption kinetic models reveals that pseudo second order kinetic model exhibited a favourable level of agreement with kinetic data (R2 = 0.999). Response surface methodology utilising central composite design was employed to evaluate various process parameters, such as initial Pb(II) concentration, pH, adsorbent dosage and sonication time on adsorption process. Results from 30 experimental runs performed in accordance with model recommendations concluded that the effect of selected parameters with an R2 value of 0.937 was adequate for the current study. In order to assess the goodness of fit and statistical significance of the model’s performance, ANOVA and Lack of Fit (LOF) tests were conducted. The findings show that Pb(II) can be easily removed from the aqueous solutions using CS as an adsorbent under optimal experimental conditions of 100 mg/l Pb(II) initial concentration, 2 g/l adsorbent dosage, pH of 8 and a sonication time of 45 min.
