description: Topological materials host robust properties, unaffected by microscopic perturbations, owing to the global topological properties of the bulk electron system. Materials in which the topological invariant can be changed by easily tuning external parameters are especially sought after. Zirconium pentatelluride (ZrTe$_5$) is one of a few experimentally available materials that reside close to the boundary of a topological phase transition, allowing the switching of its invariant by mechanical strain. Here, we unambiguously identify a topological insulator - metal transition as a function of strain, by a combination of ab initio calculations and direct measurements of the local charge density. Our model quantitatively describes the response to complex strain patterns found in bubbles of few layer ZrTe$_5$ without fitting parameters, reproducing the mechanical deformation dependent closing of the band gap observed using scanning tunneling microscopy. We calculate the topological phase diagram of ZrTe$_5$ and identify the phase at equilibrium, enabling the design of device architectures which exploit the unique topological switching characteristics of the system.

description: In the first part, we discuss the interplay between local scale invariance and metric-affine degrees of freedom from few distinct points of view. We argue, rather generally, that the gauging of Weyl symmetry is a natural byproduct of requiring that scale invariance is a symmetry of a gravitational theory that is based on a metric and on an independent affine structure degrees of freedom. In the second part, we compute the Nöther identities associated with all the gauge symmetries, including Weyl, Lorentz and diffeomorphisms invariances, for general actions with matter degrees of freedom, exploiting a gauge covariant generalization of the Lie derivative. We find two equivalent ways to approach the problem, based on how we regard the spin-connection degrees of freedom, either as an independent object or as the sum of two Weyl invariant terms. The latter approach, which rests upon the use of a new connection, denoted $\hat{\nabla}$, is particularly convenient and constitutes one of our main results.

Role of microtubule-associated protein 7 domain containing protein 3 in microtubule assembly and cell motility

description: This thesis endeavors to understand the role of a protein, microtubule-associated protein 7 domain containing protein 3 (MAP7D3) in the multiplication and motility of cancer cells. Microtubules are part of the cytoskeleton, which regulate cell division and cell motility. Current work suggests that the C-terminal region of MAP7D3 regulates the assembly of the microtubules in vitro. It also indicates that loss of MAP7D3 reduces the motility of malignant cancer cells by altering the turnover of actin, another cytoskeletal component. Therefore, targeting MAP7D3 can be used as a strategy to control the movement of malignant cancer cells to new sites.

description: The emerging all-dielectric platform exhibits high-quality ($Q$) resonances governed by the physics of bound states in the continuum (BIC) that drives highly efficient nonlinear optical processes. Here we demonstrate the robust enhancement of third-(THG) and fifth-harmonic generation (FHG) from all-dielectric metasurfaces composed of four silicon nanodisks. Through the symmetry breaking, the genuine BIC transforms into the high-$Q$ quasi-BIC resonance with tight field confinement for record high THG efficiency of $3.9\times10^{-4}$ W$^{-2}$ and FHG efficiency of $4.8\times10^{-10}$ W$^{-4}$ using a moderate pump intensity of 1 GW/cm$^{2}$. Moreover, the quasi-BIC and the resonantly enhanced harmonics exhibit polarization-insensitive characteristics due to the special $C_{4}$ arrangement of meta-atoms. Our results suggest the way for smart design of efficient and robust nonlinear nanophotonic devices.

Inflammation, which is exacerbated by obesity, is a pathophysiological cause of coronary heart disease (CHD). The Mediterranean diet (MedDiet) is recognised to prevent CHD, in part, via antiinflammatory properties, however, diet efficacy via this mechanism is unclear in patients who have developed CHD. This thesis reports intermediate outcomes in pilot study participants from the AUStralian MEDiterranean Diet (AUSMED) Heart Trial, a randomised controlled trial testing the cardiovascular health benefits of MedDiet versus low-fat diet after a coronary event. The main aims were to test the effect of 6-month ad libitum MedDiet intervention on markers of inflammation, adiposity, dietary inflammatory index (DII), and MedDiet adherence in a multi-ethnic CHD cohort. Participants (62±9 years, 83 percent male, BMI 30.0±5.1kg per m2 ) were randomised to the MedDiet (n=34) or low-fat diet (n=31). Dietitian-led interviews were held at 0-, 3- and 6-months for dietary counselling, measurement of anthropometry and body composition and collection of blood samples for pathology analyses. Dietary intake was assessed via validated MedDiet adherence questionnaire and 7-day food diaries, with DII subsequently determined. Participants adhered well to the MedDiet and this led to improved diet quality and a significantly more anti-inflammatory DII score compared with low-fat diet participants after 6-months. Despite dietary changes, the MedDiet did not significantly improve inflammatory markers (C-reactive protein, interleukin-6, tumour necrosis factor-α or adiponectin), anthropometry, body composition or visceral fat compared with the low-fat diet. This lack of effect likely relates to small sample size in a medically-treated cohort. A clinically significant impact on inflammation in CHD patients may require a larger sample, adjunct exercise intervention and or caloric restriction. This is the first demonstration in Australia that dietetic promotion of MedDiet principles would lead to greater improvements in diet quality compared to current low-fat diet recommendations in cardiac patients, which in turn could more effectively impact CHD risk markers.

This thesis was a recipient of the Nancy Millis Award for theses of exceptional merit.

Magnetic field evolution in tidal disruption events

description: When a star gets tidally disrupted by a supermassive black hole, its magnetic field is expected to pervade its debris. In this paper, we study this process via smoothed particle magnetohydrodynamical simulations of the disruption and early debris evolution including the stellar magnetic field. As the gas stretches into a stream, we show that the magnetic field evolution is strongly dependent on its orientation with respect to the stretching direction. In particular, an alignment of the field lines with the direction of stretching induces an increase of the magnetic energy. For disruptions happening well within the tidal radius, the star compression causes the magnetic field strength to sharply increase by an order of magnitude at the time of pericentre passage. If the disruption is partial, we find evidence for a dynamo process occurring inside the surviving core due to the formation of vortices. This causes an amplification of the magnetic field strength by a factor of $\sim 10$. However, this value represents a lower limit since it increases with numerical resolution. For an initial field strength of 1 G, the magnetic field never becomes dynamically important. Instead, the disruption of a star with a strong 1 MG magnetic field produces a debris stream within which magnetic pressure becomes similar to gas pressure a few tens of hours after disruption. If the remnant of one or multiple partial disruptions is eventually fully disrupted, its magnetic field could be large enough to magnetically power the relativistic jet detected from Swift J1644+57. Magnetized streams could also be significantly thickened by magnetic pressure when it overcomes the confining effect of self-gravity.

description: The Internet has become a critical component of modern civilization requiring scientific exploration akin to endeavors to understand the land, sea, air, and space environments. Understanding the baseline statistical distributions of traffic are essential to the scientific understanding of the Internet. Correlating data from different Internet observatories and outposts can be a useful tool for gaining insights into these distributions. This work compares observed sources from the largest Internet telescope (the CAIDA darknet telescope) with those from a commercial outpost (the GreyNoise honeyfarm). Neither of these locations actively emit Internet traffic and provide distinct observations of unsolicited Internet traffic (primarily botnets and scanners). Newly developed GraphBLAS hyperspace matrices and D4M associative array technologies enable the efficient analysis of these data on significant scales. The CAIDA sources are well approximated by a Zipf-Mandelbrot distribution. Over a 6-month period 70\% of the brightest (highest frequency) sources in the CAIDA telescope are consistently detected by coeval observations in the GreyNoise honeyfarm. This overlap drops as the sources dim (reduce frequency) and as the time difference between the observations grows. The probability of seeing a CAIDA source is proportional to the logarithm of the brightness. The temporal correlations are well described by a modified Cauchy distribution. These observations are consistent with a correlated high frequency beam of sources that drifts on a time scale of a month.

Enhanced storage capacity with errors in scale-free Hopfield neural networks: an analytical study

description: The Hopfield model is a pioneering neural network model with associative memory retrieval. The analytical solution of the model in mean field limit revealed that memories can be retrieved without any error up to a finite storage capacity of $O(N)$, where $N$ is the system size. Beyond the threshold, they are completely lost. Since the introduction of the Hopfield model, the theory of neural networks has been further developed toward realistic neural networks using analog neurons, spiking neurons, etc. Nevertheless, those advances are based on fully connected networks, which are inconsistent with recent experimental discovery that the number of connections of each neuron seems to be heterogeneous, following a heavy-tailed distribution. Motivated by this observation, we consider the Hopfield model on scale-free networks and obtain a different pattern of associative memory retrieval from that obtained on the fully connected network: the storage capacity becomes tremendously enhanced but with some error in the memory retrieval, which appears as the heterogeneity of the connections is increased. Moreover, the error rates are also obtained on several real neural networks and are indeed similar to that on scale-free model networks.

We obtain a Dirac-like equation by linearizing the Landau- Lifshitz-Gilbert equation in this antiferromagnetic system, in contrast to the ferromagnetic system in which a Schrödinger equation is derived. The Hamiltonian operator in the Dirac-like equation is a pseudo-Hermitian. We compute and demonstrate the relativistic Zitterbewegung (trembling motion) in the antiferromagnetic spin chain by measuring the expectation values of the wave packet position.

description: Electrical gate-manipulated exchange bias (EB) effect is a long-term goal for spintronics applications. Meanwhile, the emergence of van der Waals (vdW) magnetic heterostructures provides ideal platforms for the study of interlayer magnetic coupling. However, to date, the electrical gate-controlled EB effect has yet to be realized in vdW heterostructures. Here, for the first time, we realized electrically-controllable EB effects in a vdW antiferromagnetic (AFM)-ferromagnetic (FM) heterostructure, FePS3-Fe5GeTe2. For pristine FePS3-Fe5GeTe2 heterostructures, sizable EB effects can be generated due to the strong interface coupling, which also depend on the thickness of the ferromagnetic layers. By applying a solid protonic gate, the EB effects can be electrically tuned largely by proton intercalations and deintercalations. The EB field reaches up to 23% of the coercive field and the blocking temperature exceeds 50 K at Vg= -3.15 V. The proton intercalations not only tune the average magnetic exchange coupling, but also change the AFM configurations and transform the heterointerface between an uncompensated AFM-FM interface and a compensated AFM-FM interface. These alterations result in a dramatic modulation of the total interface exchange coupling and the resultant EB effects. The study is a significant step towards vdW heterostructure-based magnetic logic for future low-energy electronics.

description: Let $G$ be a finite group acting linearly on a vector space $V$. We consider the linear symmetry groups $\operatorname{GL}(Gv)$ of orbits $Gv\subseteq V$, where the \emph{linear symmetry group} $\operatorname{GL}(S)$ of a subset $S\subseteq V$ is defined as the set of all linear maps of the linear span of $S$ which permute $S$. We assume that $V$ is the linear span of at least one orbit $Gv$. We define a set of \emph{generic points} in $V$, which is Zariski-open in $V$, and show that the groups $\operatorname{GL}(Gv)$ for $v$ generic are all isomorphic, and isomorphic to a subgroup of every symmetry group $\operatorname{GL}(Gw)$ such that $V$ is the linear span of $Gw$. If the underlying characteristic is zero, "isomorphic" can be replaced by "conjugate in $\operatorname{GL}(V)$". Moreover, in the characteristic zero case, we show how the character of $G$ on $V$ determines this generic symmetry group. We apply our theory to classify all affine symmetry groups of vertex-transitive polytopes, thereby answering a question of Babai (1977).

description: A visualization for dynamics of a qudit spin vector in a time-dependent magnetic field is realized by means of mapping a solution for a spin vector on the three-dimensional spherical curve (vector hodograph). The obtained results obviously display the quantum interference of precessional and nutational effects on the spin vector in the magnetic resonance. For any spin the bottom bounds of the quantum speed limit time (QSL) are found. It is shown that the bottom bound goes down when using multilevel spin systems. Under certain conditions the non-nil minimal time, which is necessary to achieve the orthogonal state from the initial one, is attained at spin S=2. An estimation of the product of two and three standard deviations of the spin components are presented. We discuss the dynamics of the mutual uncertainty, conditional uncertainty and conditional variance in terms of spin standard deviations. The study can find practical applications in the magnetic resonance, 3D visualization of computational data and in designing of optimized information processing devices for quantum computation and communication.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The purpose of this study was to assess the rewards and teachers' performance in private schools. Data were collected from two private secondary Schools in Addis Ababa, Ethiopia. The researcher used the entire two high schools academic full time staffs as respondents and the second respondent groups are the two selected high schools students. To determine the second respondents group sample size, Yamane's a simplified formula for proportion is applied. The collected data analyzed by means of descriptive statistics such as frequencies, percentage, and mean. Pearson Correlation Coefficient was used to establish the relationship between motivational practices and teachers' performance in these private secondary schools. The study revealed that the teachers' are motivated highly by Non-Transactional rewards rather than Transactional rewards in both Schools. In conclusion, the results of the study indicated that there is positive relationship between Non-Transactional rewards motivational practices and teachers' performance in Deborah private secondary schools and Future Talent Academy in Addis Ababa, Ethiopia. Limitations and future directions had also been discussed. Keywords Intrinsic Rewards, Extrinsic Rewards and Teachers' performance

description: The mechanism of hydrodynamics-induced pairing of soft particles, namely closed bilayer membranes (vesicles, a model system for red blood cells) and drops, is studied numerically with a special attention paid to the role of the confinement (the particles are within two rigid walls). This study unveils the complexity of the pairing mechanism due to hydrodynamic interactions. We find both for vesicles and for drops that two particles attract each other and form a stable pair at weak confinement if their initial separation is below a certain value. If the initial separation is beyond that distance, the particles repel each other and adopt a longer stable interdistance. This means that for the same confinement we have (at least) two stable branches. To which branch a pair of particles relaxes with time depends only on the initial configuration. An unstable branch is found between these two stable branches. At a critical confinement the stable branch corresponding to the shortest interdistance merges with the unstable branch in the form of a saddle-node bifurcation. At this critical confinement we have a finite jump from a solution corresponding to the continuation of the unbounded case to a solution which is induced by the presence of walls. The results are summarized in a phase diagram, which proves to be of a complex nature. The fact that both vesicles and drops have the same qualitative phase diagram points to the existence of a universal behavior, highlighting the fact that with regard to pairing the details of mechanical properties of the deformable particles are unimportant. This offers an interesting perspective for simple analytical modeling.

description: For a given diagrammatic approximation in many-body perturbation theory it is not guaranteed that positive observables, such as the density or the spectral function, retain their positivity. For zero-temperature systems we developed a method [Phys.Rev.B 90,115134 (2014)] based on so-called cutting rules for Feynman diagrams that enforces these properties diagrammatically, thus solving the problem of negative spectral densities observed for various vertex approximations. In this work we extend this method to systems at finite temperature by formulating the cutting rules in terms of retarded $N$-point functions, thereby simplifying earlier approaches and simultaneously solving the issue of non-vanishing vacuum diagrams that has plagued finite temperature expansions. Our approach is moreover valid for nonequilibrium systems in initial equilibrium and allows us to show that important commonly used approximations, namely the $GW$, second Born and $T$-matrix approximation, retain positive spectral functions at finite temperature. Finally we derive an analytic continuation relation between the spectral forms of retarded $N$-point functions and their Matsubara counterparts and a set of Feynman rules to evaluate them.

description: Remote and in-situ observations strongly imply that the slow solar wind consists of plasma from the hot, closed-field corona that is released onto open magnetic field lines. The Separatrix Web (S-Web) theory for the slow wind proposes that photospheric motions, at the scale of supergranules, are responsible for generating dynamics at coronal-hole boundaries, which result in the closed plasma release. We use three-dimensional magnetohydrodynamic (3D MHD) simulations to determine the effect of photospheric flows on the open and closed magnetic flux of a model corona with a dipole magnetic field and an isothermal solar wind. A rotational surface motion is used to approximate photospheric supergranular driving and is applied at the boundary between the coronal hole and helmet streamer. The resulting dynamics consist primarily of prolific and efficient interchange reconnection between open and closed flux. Magnetic flux near the coronal-hole boundary experiences multiple interchange events, with some flux interchanging over fifty times in one day. Additionally, we find that the interchange reconnection occurs all along the coronal-hole boundary, even producing a lasting change in magnetic-field connectivity in regions that were not driven by the applied motions. Our results show that these dynamics should be ubiquitous in the Sun and heliosphere. We discuss the implications of our simulations for understanding the observed properties of the slow solar wind, with particular focus on the global-scale consequences of interchange reconnection.
Stability of ground states for logarithmic Schrödinger equation with a $δ^{\prime}$-interaction

description: In this paper we study the one-dimensional logarithmic Schrödinger equation perturbed by an attractive $δ^{\prime}$-interaction \[ i\partial_{t}u+\partial^{2}_{x}u+ γδ^{\prime}(x)u+u\, \mbox{Log}\left|u\right|^{2}=0, \quad (x,t)\in\mathbb{R}\times\mathbb{R}, \] where $γ>0$. We establish the existence and uniqueness of the solutions of the associated Cauchy problem in a suitable functional framework. In the attractive $δ^{\prime}$-interaction case, the set of the ground state is completely determined. More precisely: if $02$, then there exist two non-symmetric ground states. Finally, we show that the ground states are orbitally stable via a variational approach.

Axial-strain sonoelastography of the Achilles tendinopathy: diagnosis, prevention and treatment monitoring

description: Compression elastography or axial-strain sonoelastography (SE) is a relatively new ultrasound (US) based technique that estimates the stiffness or softness of a tissue by measuring the strain (displacement) caused by tissue compression. Axial-strain SE allows characterization of the differences in stiffness between the region of interest and the surrounding tissue in a large range of lesions and pathologies. To date, several studies applying axial-strain SE to assess Achilles tendinopathy, patellar tendinopathy and common extensor tendinopathy have been published with conflicting results. The discrepancy in results reported between publications raising questions regarding its reproducibility. Moreover, there are still limited data regarding the diagnostic role of SE. This thesis builds upon previous work, evaluating the applications of axial-strain SE for the diagnosis of Achilles tendinopathy, assessing the risk of developing future symptoms and monitoring the disease progression and the efficacy of intervention. Our preliminary results demonstrated that the supplementation of axial-strain SE to traditional US imaging achieved a higher sensitivity and accuracy than routine combination technique of Colour Doppler and B-mode US. The semi-quantitative strain-ratio measurement was more related to the Achilles tendon pain and functional disability compared to conventional B-mode US. The results are clinically relevant as it may allow accurate and timely diagnosis of tendon injuries, which, in turn, allow early management planning and minimise possible tendon disability. Another important contribution of this thesis was the identification of sonographic predictors for the development of Achilles tendon injuries. Intratendinous delaminations and soft tendon properties as well as increased thickening and cross-sectional area were the potential risk factors for clinically manifesting Achilles tendon pain in elite athletes. Conventional US supplemented with axial-strain SE may be able to identify at risk athletes and allow early initiation of rehabilitative protocols to prevent further tendon damage. In addition, our research has shown that following therapy, the treated Achilles tendons showed progressive stiffening in relation to the Kager’s fat, coinciding with improvement in clinical findings up to one year follow-up. This highlights the potential clinical utility of axial-strain SE as supplementary tool in routine monitoring of Achilles tendon healing after treatment. We believe the work presented in this thesis will facilitate the use of axial-strain SE for diagnosis and management of Achilles tendon injuries in routine clinical setting.
