description: In this paper, we consider the $β$ function at one-loop approximation for noncommutative scalar QED. The renormalization of the full theory, including the basic vertices, and the renormalization group equation are fully established. Next, the complete set of the one-loop diagrams corresponding to the first-order radiative corrections to the basic functions is considered: gauge, charged scalar and ghost fields self-energies, and three- and four-point vertex functions $\left$ and $\left$, respectively. We pay special attention to the noncommutative contributions to the renormalization constants. To conclude, the one-loop $β$ function of noncommutative scalar QED is then computed and comparison to known results is presented.

Thesis with publications.

Significant contemporary demographic, social, environmental and economic change is resulting in over half of all Australian farming families now comprising of a couple living alone, without a younger generation to follow on the land. Thus, older farming couples considering retirement face unprecedented challenges as they negotiate a life stage change as well as changing relationships with place and unfamiliar social landscapes. This thesis explores these issues by asking: How is ageing Australian farming couples’ retirement decision making affected by the contemporary context? This is a complex question calling for multiple theoretical perspectives, methodologies, methods and analytic frameworks to enable deep understandings of the topic. Firstly, this study utilised a Foucauldian discourse analysis to examine the discourse surrounding the draft Murray Darling Basin Plan; a major water policy reform impacting on older farmers and their plans for the future. This approach developed understandings of the environmental, social, economic and political contexts in which this study is embedded. Secondly, critical theory guided the reflection on the research process. Finally, this thesis utilised social constructionism as a theoretical approach and lenses of generativity and place identity to explore how these concepts influence and are influenced by older farming couples’ constructions of retirement within a rapidly changing context. This research has shown how the unique Australian family farming culture has been mythologised over time to form a grand narrative. The utilisation of a ‘narrative practice’ (Gubrium and Holstein, 1998) approach and Bamberg’s (2006) small story approach permitted nuanced analysis of the ways older farming couples co-construct their social world within the tight confines of a dominant culture. Findings include that some older couples construct new scripts for ageing to meet their needs in the contemporary context and these counter narratives form new strands of the dominant discourse.

description: We consider a free boundary problem for a system of PDEs, modeling the growth of a biological tissue. A morphogen, controlling volume growth, is produced by specific cells and then diffused and absorbed throughout the domain. The geometric shape of the growing tissue is determined by the instantaneous minimization of an elastic deformation energy, subject to a constraint on the volumetric growth. For an initial domain with $C^{2,α}$ boundary, our main result establishes the local existence and uniqueness of a classical solution, up to a rigid motion.

description: The transfer of football players is an important part in football games. Most studies on the transfer of football players focus on the transfer system and transfer fees but not on the transfer behavior itself. Based on the 470,792 transfer records from 1990 to 2016 among 23,605 football clubs in 206 countries and regions, we construct a directed footballer transfer network (FTN), where the nodes are the football clubs and the links correspond to the footballer transfers. A systemic analysis is conduced on the topological properties of the FTN. We find that the in-degrees, out-degrees, in-strengths and out-strengths of nodes follow bimodal distributions (a power law with exponential decay), while the distribution of link weights has a power-law tail. We further figure out the correlations between node degrees, node strengths and link weights. We also investigate the general characteristics of different measures of network centrality. Our network analysis of the global footballer transfer market sheds new lights into the investigation of the characteristics of transfer activities.

Year: 2023

description: Submission note: A thesis submitted in total fulfilment of the requirements for the degree of Doctor of Philosophy to the Department of Archaeology and History, School of Humanities and Social Sciences, College of Arts, Social Sciences and Commerce, La Trobe University, Bundoora.

The public version of this thesis does not contain all material submitted for examination.

The nature of the relationship between the ancient Maya and the city of Teotihuacan has become a subject of great interest and debate in the archaeological field, from the early discoveries made by the Carnegie Institution of Washington (CIW) at Kaminaljuyu, Guatemala up to the present day (Kidder, Jennings and Shook 1946; Michaels and Sanders 1977; Coggins 1975; Proskouriakoff 1993; Stuart 2000; Braswell 2003; Nielsen 2003). The search for a satisfactory answer that could explain this complex phenomenon has divided the scholar’s opinion into two streams, where the presence of Teotihuacan in the Maya area has been view either as a product of commerce and emulation for prestige and legitimation or as a result of political and military dominance from Central Mexico (Stuart 2000: 465). The main objective of this dissertation is to present an analysis of the ritual interaction between the Maya and Teotihuacan during the Classic period (AD 250-900). The study of the presence of Teotihuacan in the Maya area was addressed through an extensive study of Teotihuacan influence in the symbolic representations and glyphic texts of the Maya. As a result, the present work collected an exhaustive catalogue for ten glyphic terms associated with the presence and influence of Teotihuacan during the Classic period. Through the study of toponyms, deities, military orders and warfare, this work intends to provide a better understanding of the role of ritual in the process of cultural interaction and its implications in the historical and cultural development of the Maya area during the Classic period.

description: We construct and study general static, spherically symmetric, magnetically charged solutions in Einstein-Maxwell-dilaton gravity in four dimensions. That is, taking Einstein gravity coupled to a ${\rm U}(1)$ gauge field and a massless dilaton$\unicode{x2014}$e.g., the action in the low-energy limit of string theory or Kaluza-Klein reduction$\unicode{x2014}$with arbitrary dilaton coupling, we build a three-parameter family of objects characterized by their mass, charge, and dilaton flux, generalizing the well known Garfinkle-Horowitz-Strominger black hole. We analyze the near-extremal and near-horizon behavior in detail, finding new warped geometries. In a particular limit, where the geometry reduces to the recently discovered customizable ${\rm AdS}_2 \times S^2$ of Einstein-Maxwell-dilaton gravity, we compute the static s-wave linearized solutions and characterize the anabasis relating the horizon perturbations to their nonlinear completions within our generalized family of spacetimes.

description: It is of great significance to identify the characteristics of time series to qualify their similarity. We define six types of triadic time-series motifs and investigate the motif occurrence profiles extracted from logistic map, chaotic logistic map, chaotic Henon map, chaotic Ikeda map, hyperchaotic generalized Henon map and hyperchaotic folded-tower map. Based on the similarity of motif profiles, we further propose to estimate the similarity coefficients between different time series and classify these time series with high accuracy. We further apply the motif analysis method to the UCR Time Series Classification Archive and provide evidence of good classification ability for some data sets. Our analysis shows that the proposed triadic time series motif analysis performs better than the classic dynamic time wrapping method in classifying time series for certain data sets investigated in this work.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2004

description: Ethiopia spends million of dollars to meet its energy requirement, it is estimated around 20-30 million dollars is spent for the purchase of furnace oil for cement sectors only. In order to change the country's economic situation and to come-out of poverty it is necessary to develop and utilize the country's energy potential. For the reason of fuel economy cement plants all over the world are switching over from fuel oil or gas to coal for their kiln operation. Ethiopia has discovered large potential low grade coals at different areas. The development and the utilization of this indigenous coal as an energy source for all energy consuming sectors will be a major issue in this country in near future. The study aims to determine the potential use of one of the indigenous coal as a substitute in place of furnace oil in cement industry. Results from the analysis and comparisons of Yayu coal quality revealed the possibility of using Indigenous coal in place of furnace oil up to a certain percent. Based on the results the study attempts to select the equipments required if Yayu coal is replaced in place of fuel oil in Mugher Cement Enterprise. Substantial investment for additional facilities and equipments are required, and as a consequent considerable saving in production cost in addition to the reduction of foreign currency can be achieved through the switch over to indigenous coal. Additionally the study revealed air pollution, spontaneous coal fires and coal dust explosion are the major concerns of cement plant if this indigenous coal is used in place of furnace oil. In view of this the study recommended cement plants to see this alternative source of energy and to identify their concerns as soon as possible.

description: We show that the quantum Zeno effect gives rise to the Hall effect by tailoring the Hilbert space of a two-dimensional lattice system into a single Bloch band with a nontrivial Berry curvature. Consequently, a wave packet undergoes transverse motion in response to a potential gradient -- a phenomenon we call the Zeno Hall effect to highlight its quantum Zeno origin. The Zeno Hall effect leads to retroreflection at the edge of the system due to an interplay between the band flatness and the nontrivial Berry curvature. We propose an experimental implementation of this effect with ultracold atoms in an optical lattice.

description: Price changes are induced by aggressive market orders in stock market. We introduce a bivariate marked Hawkes process to model aggressive market order arrivals at the microstructural level. The order arrival intensity is marked by an exogenous part and two endogenous processes reflecting the self-excitation and cross-excitation respectively. We calibrate the model for an SSE stock. We find that the exponential kernel with a smooth cut-off (i.e. the subtraction of two exponentials) produces much better calibration than the monotonous exponential kernel (i.e. the sum of two exponentials). The exogenous baseline intensity explains the $U$-shaped intraday pattern. Our empirical results show that the endogenous submission clustering is mainly caused by self-excitation rather than cross-excitation.

description: In the present work we report on the behavior of ferrofluid microdrops in an immiscible nonmagnetic carrier fluid and vice versa subjected to the action of magnetic fields. Our experiments evidence previously unexplored instability and flow patterns. We investigated the instabilities initiated by constant magnetic field and by combined action of constant and rotating magnetic fields. The observed instabilities lead to the formation of various microdrop configurations such as star-like and comb-like shapes, bending deformation, ridges and crests, spiral arms and rings, etc. The reviled peculiarities of the microscopic drops behavior can be of interest in applications to the ferrofluid-based microfluidics.

description: Similar to charitable giving in real world, donation behaviors play an important role in the complex interactions among individuals in virtual worlds. However, it is not clear if the donation process is random or not. We investigate this problem using detailed data from parallel virtual worlds adhered to a massively multiplayer online role-playing game. We find that the inter-donation durations follow power-law-tailed distributions distributed with an average tail exponent close to 1.91, have strong long-range correlations, and possess multifractal features. These findings indicate that the donation process is non-Poissonian, which has potential worth in modeling the complicated individuals behaviors in virtual worlds.

description: The quantum-to-classical correspondence is often quantified in dynamics by a quantity referred to as the out-of-time-order correlator (OTOC). In chaotic systems, the OTOC is expected to grow exponentially at early time, characteristic of a Lyapunov exponent, however, exponential growth can also occur for integrable systems. Here we investigate the OTOC for realistic diatomic molecular potentials in one degree of freedom, finding that the OTOC can grow exponentially near the dissociation energy of the moelcule. Further, this dynamics is tied to the classical dynamics of the atoms at the outer classical turning point of the potential. These results should serve to guide and interpret dynamical chaos in more complex molecules.

description: This paper investigates the effect of cross-shareholding on stock price synchronicity, as a measure of price informativeness, of the listed firms in the Chinese stock market. We gauge firms' levels of cross-shareholdings in terms of centrality in the cross-shareholding network. It is confirmed that it is through a noise-reducing process that cross-shareholding promotes price synchronicity and reduces price delay. More importantly, this effect on price informativeness is pronounced for large firms and in the periods of market downturns. Overall, our analyses provide insights into the relation between the ownership structure and price informativeness.

description: This paper studies the time-averaged energy dissipation rate $\langle \varepsilon_{SMD} (u)\rangle$ for the combination of the Smagorinsky model and damping function. The Smagorinsky model is well known to over-damp. One common correction is to include damping functions that reduce the effects of model viscosity near walls. Mathematical analysis is given here that allows evaluation of $\langle \varepsilon_{SMD} (u)\rangle $ for any damping function. Moreover, the analysis motivates a modified van Driest damping. It is proven that the combination of the Smagorinsky with this modified damping function does not over dissipate and is also consistent with Kolmogorov phenomenology.

description: The classical Kolmogorov-Arnold-Moser (KAM) theorem provides the underlying mechanism for the stability of the solar system under some small chaotic perturbations. Despite many previous efforts, any quantum version of the KAM theorem remains elusive In this work, we provide a quantum KAM theorem in the context of the anisotropic Dicke model which is the most important quantum optics model. It describes a single mode of photons coupled to $ N $ qubits with both a rotating wave (RW) term and a counter-RW (CRW) term. As the ratio of the CRW over the RW term increases from zero to one, the systems evolves from quantum integrable to quantum chaotic. We establish a quantum KAM theorem to characterize such a evolution quantitatively by both large $ N $ expansion and Random Matrix Theory and find agreement from the two complementary approaches. Connections and differences between the Dicke models and Sachdev-Ye-Kitaev (SYK) or hybrid SYK models are examined. Possible Quantum KAM theorem in terms of other quantum chaos criterion such as quantum Lyapunov exponent is also discussed.

description: El conocimiento racionalista desarrollado por la revolución científica de los siglos XVI y XVII –reforzado más tarde por la Ilustración y el positivismo del XIX– construyó una noción de yo pensante absoluto al que se le otorgó una función preponderante para la constitución del mundo objetivado. Como respuesta a esta noción unidimensional de la mismidad en el arte, la estética del poeta venezolano Eugenio Montejo (1938-2008), nutrida de las estéticas románticas y vanguardistas, plantea una noción axiológica de la Otredad pensada desde lo Otro. El presente trabajo se interesa en estudiar las configuraciones y principios estéticos del poemario Terredad (1978), teniendo en cuenta las despersonalizaciones del yo y la analogía del Otro como camino hacia una Otredad poliórfica del todo; es decir, un sujeto plural constituido lingüística y mito-poéticamente. En este sentido, se observa cómo el poeta venezolano aborda el problema ético-estético de la relación mismidad y alteridad en el discurso literario contemporáneo. A partir de una onto-poética (abordada con un marco conceptual que tiene en cuenta los vínculos entre mito y poesía, ética y poesía, y filosofía y poesía), se evidencia cómo la Otredad lírica del poeta venezolano replantea en Terredad la visión antropocéntrica del yo poético absoluto de la poesía moderna europea y redimensiona el vínculo epistémico-estético racionalista sujeto-objeto entre el hombre y la naturaleza al proponer una relación intersubjetiva sujeto-sujeto entre el ser humano y la totalidad del mundo, entendida esta como una Otredad del todo

description: Citric acid is an organic acid with numerous industrial application. It is extensively used in the food and beverage industry as it combines a pleasant taste with low toxicity and sweetness. It can be produced from different materials like molasses that has sucrose content of 32%. In Ethiopia, some of the molasses were used for ethanol production and other purposes, but the remaining has been exported to abroad. This study investigated that the utilization of molasses to use as a raw material for citric acid production under different fermentation conditions with submerged fermentation method in the laboratory using 250mL Erlenmeyer flask as the small scale laboratory fermentor by using Aspergillus niger. The effect of temperature (25, 30, and 35℃), fermentation time (96, 144, 196h) and pH (2, 4, and 6) of fermentation condition for citric acid yield test result were investigated. The experimental design was done by using Design Expert 6.0.8 software for three factors and Response Surface with 3- level factorial design type in optimization study. The minimum citric acid yield was found to be 20.23 g/L after the fermentation time of 96h, temperature 25℃ and pH 2. A maximum citric acid yield of 40.08 g/L was achieved under selected optimal condition of (fermentation time 156h, temperature 30℃ and pH 3.89) with high value of combined desirability. From the model regression equation developed, the linear terms of temperature, and time had a positive effect and a pH had a negative effect on response yield. The quadratic terms (pure and interaction quadratic terms) had a negative effect on extraction yield except fermentation time and pH interaction. Incubation time had a more weighty linear effect on yield as compared to fermentation temperature and pH. The quality of the product obtained under optimized condition was assessed with Atomic Absorption Spectroscopy (Buck of Scientific 210 VGP AAS, USA) and UV visible Spectrophotometer. The results revealed that the heavy metal content of the sample was below detection limit except Iron and purity of 99.2% respectively. The study indicated that utilization of molasses for citric acid production is considered not only as a positive option in terms of reducing imported citric acid, but also, as an attractive option in means of providing job opportunity and minimizing environmental pollution.

description: Heavily electron-doped iron-selenide (HEDIS) high-transition-temperature (high-$T_{\rm{c}}$) superconductors, which have no hole Fermi pockets, but have a notably high $T_{\rm{c}}$, have challenged the prevailing $s$$_\pm$ pairing scenario originally proposed for iron pnictides containing both electron and hole pockets. The microscopic mechanism underlying the enhanced superconductivity in HEDIS remains unclear. Here, we used neutron scattering to study the spin excitations of the HEDIS material Li$_{0.8}$Fe$_{0.2}$ODFeSe ($T_{\rm{c}}$ = 41 K). Our data revealed nearly ring-shaped magnetic resonant excitations surrounding ($π$, $π$) at $\sim$ 21 meV. As the energy increased, the spin excitations assumed a diamond shape, and they dispersed outward until the energy reached $\sim$ 60 meV and then inward at higher energies. The observed energy-dependent momentum structure and twisted dispersion of spin excitations near ($π$, $π$) are analogous to those of hole-doped cuprates in several aspects, thus implying that such spin excitations are essential for the remarkably high $T_{\rm{c}}$ in these materials.

description: Bose-Einstein condensation happens as a gas of bosons is cooled below its transition temperature, and the ground state becomes macroscopically occupied. The phase transition occurs in the thermodynamic limit of many particles. However, recent experimental progress has made it possible to assemble quantum many-body systems from the bottom up, for example, by adding single atoms to an optical lattice one at a time. Here, we show how one can predict the condensation temperature of a Bose gas from the energy fluctuations of a small number of bosons. To this end, we make use of recent advances in Lee-Yang theories of phase transitions, which allow us to determine the zeros and the poles of the partition function in the complex plane of the inverse temperature from the high cumulants of the energy fluctuations. By increasing the number of bosons in the trapping potential, we can predict the convergence point of the partition function zeros in the thermodynamic limit, where they reach the inverse critical temperature on the real axis. Using less than 100 bosons, we can estimate the condensation temperature for a Bose gas in a harmonic potential in two and three dimensions, and we also find that there is no phase transition in one dimension as one would expect.
