description: Quantum computers can solve specific complex tasks for which no reasonable-time classical algorithm is known. Quantum computers do however also offer inherent security of data, as measurements destroy quantum states. Using shared entangled states, multiple parties can collaborate and securely compute quantum algorithms. In this paper we propose an approach for distributed quantum machine learning, which allows multiple parties to securely perform computations, without having to reveal their data. We will consider a distributed adder and a distributed distance-based classifier.

description: The Ethiopian Oil and Gas sector is presented as one of the pillars of the Growth and transformation plans proposed by the Government of Ethiopia. Although the activities in industry dates back to the 1940s, there has not been any commercialization of Petroleum or Natural Gas to date. This project work aims to assess the project implementation challenges in the Ethiopian Oil and Gas industry. An exploratory research design is employed for the research. The research work followed a qualitative approach by using questionnaire and interview as data collection tools. A total of sixteen participants, twelve from the oil and gas companies and four from the regulatory were selected to participate in the research. The participants were selected using purposive sampling technique. The result of the study identified more than 85% of the respondents claimed having both time and cost overrun in their project. More than 90% of the respondents described the project management style of their company as a mix of traditional and agile project management. The research showed subsurface complexity, lack of national technical experts, unavailability of advanced technology for seismic, drilling, well logging, mud logging and other similar operations locally, inability to attract investors, unanticipated change on project scope, and unanticipated project cost existence as the major challenges affecting the implementation of the oil and gas projects in Ethiopia. The research points out the solutions for the challenges in oil and gas project implementation are the government should have a more incentivizing policy in place and should create competent workforce that manages oil and gas projects. It is also suggested more work is required to create a better understanding of how the industry works from the federal to the kebele levels of administration.

description: Higher-order exceptional points in the spectrum of non-Hermitian Hamiltonians describing open quantum or wave systems have a variety of potential applications in particular in optics and photonics. However, the experimental realization is notoriously difficult. Recently, Q. Zhong et al. [Phys. Rev. Lett. 125, 203602 (2020)] have introduced a robust construction where a unidirectional coupling of two subsystems having exceptional points of the same order leads generically to a single exceptional point of twice the order. Here, we investigate this scheme in a different manner by exploiting the nilpotency of the traceless part of the involved Hamiltonians. We generalize the scheme and derive a simple formula for the spectral response strength of the composite system hosting a higher-order exceptional point. Its relation to the spectral response strengths of the subsystems is discussed. Moreover, we investigate nongeneric perturbations. The results are illustrated with an example.

Reciprocal role modelling: A constructivist grounded theory
Creators: name: Hoare, Karen Jean
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: Information use by practice nurses in New Zealand has not been widely described in the literature. Practice nurses in New Zealand, the United Kingdom and Australia are usually employed by general practitioners. Compared with their peers in the United Kingdom, there is little evidence to suggest that New Zealand practice nurses provide the same autonomous nurse-led services. Providing nurse-led services is contingent on knowledge and skills and the ability to source and use contemporary information. In 2008, a New Zealand Ministry of Health programme of supporting new graduate hospital placements through finance and mentorship expanded to include primary health care, and a number of new graduate nurses were placed in general practice. This research sought to investigate information use by practice nurses in general practice in New Zealand. Using a constructivist grounded theory design, the author’s own general practice was the site of an initial ethnographic phase. Theoretical sensitivity was heightened by observing, conversing and documenting field notes in this environment. Following the ethnographic period, data were elicited from eleven practice nurses using an unstructured, in-depth interview technique. Of these participants, five were new graduates and six were experienced practice nurses. Reciprocal role modelling is the constructed grounded theory of this thesis. Within supportive multi-disciplinary environments, new graduate nurses (all from the Millennial generation) and experienced practice nurses (Generation X or Baby Boomers) become willing to enter into a relationship. Once they feel confident with their mentors, new graduate nurses subsequently deploy their unconscious expertise at sourcing information. Experienced practice nurses are then realising potential in the new graduates, the second category of the theory. Following this realisation, a mutual reciprocal arrangement follows where the new graduate nurse learns clinical and communication skills and knowledge of the community, while the experienced practice nurse discovers Internet sources of best practice information. This information is subsequently embedded into their practice and alternate avenues of continuing professional development to encourage their critical thinking. The final category of becoming better practitioners is the outcome of reciprocal role modelling. This theory has widespread implications for the thorny issue of getting evidence into general practice in New Zealand and elsewhere.

We compute the perturbational quantities $g(a)$, $δ_{c}(z_{c})$, $λ(z_{c})$, $ξ(z_{c})$, $Δ_{vir}(z_{c})$, $\log[νf(ν)]$ and $\log[n(k)]$ for the new agegraphic dark energy model and compare the results with those of EdS and $ΛCDM$ models. We find that there is a dark energy dominated universe at low redshifts and a matter dominated universe at high redshifts in agreement with observations. Also, the size of structures, the overdense spherical region, and the halo size in the new agegraphic dark energy model are found smaller, denser, and larger than those of EdS and $ΛCDM$ models. We compare our results with the results of tachyon scalar field and holographic dark energy models.

Understanding aggression and victimisation in first-episode psychosis using a social information processing framework
Creators: name: Malone, Aisling
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: Current literature has established that the prevalence of both aggression and victimisation are elevated in psychotic illness. There is also evidence to suggest that these phenomena may be related. While research into aggression in psychosis is long-standing, little is currently known regarding the risks for victimisation. The goal of the current study was to use contemporary psychological theories of aggression and victimisation to explore possible reasons for the increased risk of both in psychotic illness. Social information processing difficulties, specifically impairments in facial affect recognition, were posited as a potential contributor to this relationship. The sample comprised 74 males, aged 16 to 28, currently engaged with an early psychosis service in Victoria, Australia. All participants were given a battery of measures including a computerised facial affect recognition task, as well as measures of aggression, victimisation, substance use, cognitive ability, psychopathy, and childhood trauma. Aggression and victimisation were not related in the current study. Multiple regression analysis revealed that aggression was predicted by psychopathic personality traits, alcohol use and IQ, but was not related to facial affect recognition. Victimisation, however, was significantly associated with impairments in emotion recognition. Risk of victimisation was predicted by poorer recognition of sadness, and by psychopathic personality traits. These results contribute to psychological understandings of aggression and victimisation in psychotic illness, and have implications for treatment. These results also highlight possible directions for future research.

The discrete state is found to generate more than one virtual state pole or more than one pair of resonance poles in different Riemann sheets in different situations. The form factors could also generate new states on different sheets. All these states can appear in the generalized completeness relation.

description: Nanoscale magnetic skyrmions are considered as potential information carriers for future spintronics memory and logic devices. Such applications will require the control of their local creation and annihilation, which involves so far solutions that are either energy consuming or difficult to integrate. Here we demonstrate the control of skyrmion bubbles nucleation and annihilation using electric field gating, an easily integrable and potentially energetically efficient solution. We present a detailed stability diagram of the skyrmion bubbles in a Pt/Co/oxide trilayer and show that their stability can be controlled via an applied electric field. An analytical bubble model, with the Dzyaloshinskii-Moriya interaction imbedded in the domain wall energy, account for the observed electrical skyrmion switching effect. This allows us to unveil the origin of the electrical control of skyrmions stability and to show that both magnetic dipolar interaction and the Dzyaloshinskii-Moriya interaction play an important role in the skyrmion bubble stabilization.

Effective techniques for digital image processing

Publisher: name: La Trobe
Year: 2023

description: “A picture is worth a thousand words”. Digital images have not only sent film images to history but also found various applications in many fields such as in photography, medicine, engineering and science. There has been continuous research on digital image processing, and many state-of-the-art methods have been introduced. This research aims at investigating important problems and developing effective algorithms in the areas of digital image processing and computer vision. The important problems studied in this thesis include image filtering, color constancy and depth estimation. Image filtering is the first problem studied in the thesis. The goal of image filtering is to remove noise and undesirable textures in an image. Noise may be presented in an image during image formation, storage and transmission. Removing noise with awareness of fine details and sharp edges is a challenging task. This thesis proposes two effective methods for edge-aware image filtering. The basic idea of the first method is to identify a pixel which is heavily corrupted by noise. This pixel will be eliminated from the filtering process applied to its neighboring pixels. In the second method, the filtering process is formulated as an optimization problem constrained by the local smoothness in the output image. Color constancy is the second problem studied in this thesis. Color constancy accounts for the ability of maintaining the correct color of the scene when light sources vary. In a typical digital image acquisition system, an image sensor receives energy reflected from objects of the scene. The spectrum of energy depends on the object and illumination. Extracting light energy contributed by illumination is a crucial task of digital image processing. This thesis proposes an efficient way to automatically correct the color of an image based on low level image features. Due to its simplicity, the proposed method can be implemented in devices with low computational power such as consumer digital cameras. Depth estimation is the third problem investigated this thesis. Since a digital image is a 3D scene projected to a 2D plane, it does not directly convey the geometric structure of the scene. In order to infer the depth information, two images of the same scene are used. This thesis provides a detailed study on depth estimation methods and proposes an algorithm based on the stereo vision approach.

description: The HADES collaboration has extracted dilepton mass spectra for $π^-$ induced reactions on the proton from a comparison of data taken on C and CH$_2$ targets. The spectra were interpreted in terms of different versions of vector meson dominance. Here we present results obtained from the theory and generator GiBUU. We first check the subtraction procedure used and then discuss the obtained mass spectra for the proton target. We point out that any conclusions on the version of VMD requires the knowledge of the $ρ$ spectral function in the interesting mass region.
Extraction and Optimization of Process Parameters for Xylitol Production using Microbes from Corncobs
Creators: name: Hana, Mesfin
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: This Research paper aimed mainly on the extraction of xylitol from corncob hydrolysate and optimization of fermentation parameters such as; fermentation period, yeast dose and initial pH. Raw corn cobs were collected from market in Addis Ababa, Ethiopia, and was hydrolyzed with 1% (w/w) dilute sulfuric acid. Hydrolysate was detoxified by activated carbon treatment and fermentation was carried out using the well-known xylitol producing Candida yeast, Candida mogii. Serial dilution method, Colony Forming Unit, was used to enumerate yeast cells present in a milliliter of inoculum. Box Behnken experimental design was employed to correlate the fermentation parameters to xylitol yield. Yeast dose was expressed in terms of percentage volume of fermentation medium on levels of 5%, 7.5% and 10% along with three levels of initial pH, 4.5, 5 and 5.5, and fermentation period of 24, 48 and 72 hours. HPLC with RI detector and Amine NH2 column was used to determine xylitol concentration. The highest xylitol yield of 23.56 gL was obtained at 5% yeast dose, 45 pH and 45.68 hours. The results showed area of xylitol peak and the presence of sugar residuals. According to the experiment design, all three parameters have significant effect on xylitol yield. The effect of fermentation period and yeast dose showed dominant effect. The combined effect of yeast dose with pH, and yeast dose with fermentation period were also observed to be significant. The adequacy of the model was tested by analysis of variance. The value of R-squared for the developed correlation is 0.9821implying 98.21 percent variation in response is attributed to the experimental variables studied. In generally, this study has shown an alternative for the chemical production of xylitol can be carried out by candida mogii with economic and environmental friendly conditions from agricultural residue as lignocellulosic material. The yield of xylitol was promising with all parameters and down-stream process.

The molecular mechanisms of the interaction between complement proteases and substrates.
Creators: name: Duncan, Renee Charlene
Publisher: name: Monash University

Subjects: Uncategorized

description: MASP-2 and C1s are serine proteases of the lectin and classical complement pathways, respectively. As executioners of complement, their role in cleaving their substrates C4 and C2 is imperative to both innate and adaptive immunity, resulting in the formation of the key complement C3 convertase, C4bC2a. The dysregulated activation of these complement pathways has been shown to contribute to a number of diseases, thus there is the need to develop therapeutic molecules to control such proteases. Knowledge of the precise molecular mechanism whereby the proteases interact with their substrates will be key to the development of such therapeautic molecules. The proteases have similar domain structures and share 38% sequence identity, but the molecular interaction of the two proteases with their substrate C4 is quite unique. It has been shown in previous studies that MASP-2 cleaves C4 with high efficiency, while in comparison, C1s is significantly slower, with many studies indicating that the CCP domains of MASP-2 and C1s play a role in these differences. It has been suggested that the CCP domains are the location of an exosite, a site distant from the active site, which assists in correct conformational placement of the substrate C4 for efficient cleavage. This study has investigated the contribution of each domain of the catalytic region of the enzymes, CCP1, CCP2 and SP, to the binding and cleavage of C4. The work was carried out using a range of binding and cleavage assays, including measurement of affinity using an ELISA, catalytic efficiency by determining EC50 values, as well as kinetic assays and analytical affinity chromatography.

description: We employ the domain wall fermion (DWF) formulation of the Thirring model on a lattice in 2+1+1 dimensions and perform $N=1$ flavor Monte Carlo simulations. At a critical interaction strength the model features a spontaneous $\mathrm{U}(2)\rightarrow\mathrm{U}(1)\otimes \mathrm{U}(1)$ symmetry breaking; we analyse the induced spin-0 mesons, both Goldstone and non-Goldstone, as well as the correlator of the fermion quasiparticles, in both resulting phases. Crucially, we determine the anomalous dimension $η_ψ\approx 3$ at the critical point, in stark contrast with the Gross-Neveu model in 3$d$ and with results obtained with staggered fermions. Our numerical simulations are complemented by an analytical treatment of the free fermion correlator, which exhibits large early-time artifacts due to branch cuts in the propagator stemming from unbound interactions of the fermion with its heavy doublers. These artifacts are generalisable beyond the Thirring model, being an intrinsic property of DWF, or more generally Ginsparg-Wilson fermions.

This finding suggests that CSE can be used to fix renormalization constants for axial current density. Explaining the suppression of the CSE which we observe for topologically nontrivial gauge field configurations on small lattices, we also argue that CSE vanishes for self-dual non-Abelian fields inside instanton cores.

The Relationship between Project Governance and Project Success: The case of Implemented Projects in African Union Commission
Creators: name: Kebede, Abraham
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Today, complicated organizational arrangements involving several independent economic transactions are required to enable the successful delivery of large projects. Project governance is one of the important pillars in ensuring successful project delivery. So, projects that have clearly defined leadership, responsibilities, reporting lines and communication between all parties i.e. effective governance contribute to project success factors. The study looks at the relationship between project governance and project success from the agency theory and stewardship point of view. So, project governance was operationalized as the extent of corporate governance and organizational control by the parent organization over its projects. A cross-sectional organizational wide online survey conducted on implemented projects in numerous sectors in African Union Commission and yielded 95 usable responses. Factor and regression analyses indicate that project success correlates with increasing stakeholder orientation of the parent organization, while the organizational control dimensions do not correlate with project success. Thus, managers influencing the design of project governance should be aware of the importance of a stakeholder orientation for project success and that control structures that foster behavior or outcome control, do not correlate of impact project success on a global basis, but may do so in the particular circumstances of their projects

description: We demonstrate that the existence of a Hermitian time-dependent intertwining operator that maps the non-Hermitian time-dependent energy operator to its Hermitian conjugate and its right to its left eigenstates guarantees the reality of the instantaneous energies. This property holds throughout all three $\cal{PT}$-regimes, in the time-independent scenario referred to as the $\cal{PT}$-symmetric regime, the exceptional point and the spontaneously broken $\cal{PT}$-regime. We also propose a modified adiabatic approximation consisting of an expansion of the wavefunctions in terms the instantaneous eigenstates of the energy operator, instead of the usually used eigenfunctions of the Hamiltonian. We show that this proposal always leads to real Berry phases. We illustrate the working of our general proposals with two explicit examples for a time-dependent non-Hermitian spin model.

description: Dimensionality plays an essential role in determining the anomalous non-Fermi liquid properties in heavy fermion systems. So far most heavy fermion compounds are quasi-two-dimensional or three-dimensional. Here we report the synthesis and systematic investigations of the single crystals of the quasi-one-dimensional Kondo lattice CeCo$_2$Ga$_8$. Resistivity measurements at ambient pressure reveal the onset of coherence at $T^*\approx 20\,$K and non-Fermi liquid behavior with linear temperature dependence over a decade in temperature from 2 K to 0.1 K. The specific heat increases logarithmically with lowering temperature between 10 K and 2 K and reaches 800 mJ/mol K$^2$ at 1 K, suggesting that CeCo$_2$Ga$_8$ is a heavy fermion compound in the close vicinity of a quantum critical point. Resistivity measurements under pressure further confirm the non-Fermi liquid behavior in a large temperature-pressure range. The magnetic susceptibility is found to follow the typical behavior for a one-dimensional (1D) spin chain from 300 K down to $T^*$, and first-principles calculations predict flat Fermi surfaces for the itinerant $f$-electron bands. These suggest that CeCo$_2$Ga$_8$ is a rare example of the quasi-1D Kondo lattice, but its non-Fermi liquid behaviors resemble those of the quasi-two-dimensional YbRh$_2$Si$_2$ family. The study of the quasi-one-dimensional CeCo$_2$Ga$_8$ family may therefore help us to understand the role of dimensionality on heavy fermion physics and quantum criticality.

description: The results of modeling shear flows in classical two-dimensional dipole systems are presented. We used the method of non-equilibrium molecular dynamics to calculate the viscosity at various shear rates. The coefficients of shear viscosity are given in the limit of low shear rates for various regimes of interparticle correlation from a weakly correlated gaseous state to a strongly non-ideal liquid state near the crystallization point. The effect of shear thinning in 2D dipole systems is reported at small values of the coupling parameter. In addition, it is shown that dipole systems can become both less and more viscous due to the presence of a screening medium, depending on the degree of interparticle correlation. The optimal simulation parameters are discussed within the framework of the method of nonequilibrium molecular dynamics for determining the shear viscosity of two-dimensional dipole systems. Moreover, we present a simple fitting curve which provides universal scaling law for both bare dipole-dipole interaction and screened dipole-dipole interaction.

description: La interpretación de textos narrativos es fundamental para desarrollar en los educandos competencias de comprensión lectora que contribuyan a su desarrollo formativo, lo cual debe iniciar desde el grado preescolar, no obstante, en la I. E. Nuestra Señora del Rosario de San Antero, no existe abordaje al respecto, por tal motivo, este trabajo tiene como objetivo implementar un blog en Blogger para el mejoramiento de la interpretación de textos narrativos a partir de imágenes, mediante un tipo de investigación cualitativa que se enmarca en el modelo de investigación acción educativa, desarrollado en una muestra de 12 niños de grado preescolar. Este proceso inicia con la implementación de una prueba diagnóstica que evidenció las falencias de los infantes a la hora de identificar, acomodar y relacionar imágenes, por ello se diseñó un blog educativo en Blogger, estructurado con 4 actividades que facilitan la acomodación, la selección, identificación de personajes y relación de imágenes, que tras su implementación mostró que la facilidad del uso de dispositivos móviles con actividades lúdicas e interactivas, ayudaba a los niños a mejorar las falencias previas, logrando el objetivo de la investigación, constatado por medio de una prueba de salida que evidenció que un alto porcentaje de los estudiantes alcanzó las competencias planteadas.

description: The validity of the Coleman mechanism, which automatically tunes the fundamental constants, is examined in two-dimensional and four-dimensional quantum gravity theories. First, we consider two-dimensional Euclidean quantum gravity on orientable closed manifolds coupled to conformal matter of central charge $c \leq1$. The proper time Hamiltonian of this system is known to be written as a field theory of noncritical strings, which can also be viewed as a third quantization in two dimensions. By directly counting the number of random surfaces with various topologies, we find that the contribution of the baby universes is too small to realize the Coleman mechanism. Next, we consider four-dimensional Lorentzian gravity. Based on the difference between the creation of the mother universe from nothing and the annihilation of the mother universe into nothing, we introduce a non-Hermitian effective Hamiltonian for the multiverse. We show that Coleman's idea is satisfied in this model and that the cosmological constant is tuned to be nearly zero. Potential implications for phenomenology are also discussed.
