description: This thesis describes the establishment of a new fabrication facility for the realization of annealed and reverse proton exchanged waveguides in congruent lithium niobate at Grith University{Centre for Quantum Dynamics, and their application in dierent contexts of integrated quantum photonics technologies. We demonstrated the development of an accurate numerical model for the design of waveguides in X-cut and Z-cut substrates and high quality fabrication of both quasi-phase matched quadratic nonlinear waveguides and fast electro-optic waveguide modulators. Within the context of nonlinear optical processes, we demonstrated a newly proposed method which eciently reconstruct the biphoton state produced through spontaneous parametric down-conversion by the use of only classical measurements. The validity of the method is tested by a direct comparison with photon-coincidence counting measurements in a multi-channel integrated nonlinear device fabricated in our facility. We also implemented the rst frequency conversion of 369:5 nm light {resonant with the transition of Yb+ trapped ions{ to the 1550 nm telecom wavelength range with a periodically poled waveguide fabricated by the reverse proton exchange technique. Within the context of electro-optical processes, we showed the rst active demultiplexing of single-photons emitted from a quantum dot source with a single integrated device made of a network of electro-optically tunable directional couplers.

description: Misiolek has shown that the Camassa-Holm (CH) equation is a geodesic flow on the Bott-Virasoro group. In this paper it is shown that the Camassa-Holm equation for the case $κ=0$ is the geodesic spray of the weak Riemannian metric on the diffeomorphism group of the line or the circle obtained by right translating the $H^1$ inner product over the entire group. This paper uses the right-trivialisation technique to rigorously verify that the Euler-Poincaré theory for Lie groups can be applied to diffeomorphism groups. The observation made in this paper has led to physically meaningful generalizations of the CH-equation to higher dimensional manifolds (see Refs. \cite{HMR} and \cite{SH}).

 Remarks. The descriptions of the species are poor, including the original one. For instance, Brunson (1950) due to the small size of the specimens and the microscopical technique used at the time, was not able to ascertain the presence of the scales from which the spines originate. No other description of the species from the USA exists. The description of the Indian specimens is even more scarce, so much so that the question arises as to which bases the authors may have been used to attribute them with certainty to C. vulgaris. Indeed, nowadays there are several gastrotrich species whose general traits may match the insufficient original description of C. vulgaris. In the light of this difficulty, we consider the taxon C. vulgaris to be a species inquirenda. In absence of a new, most complete description of the American specimens (possibly from Michigan), any records from distant geographic areas (i.e., India) appear to be unsound; consequently, this species should not be considered part of the Indian fauna.

description: The question of how we form memories has fascinated scientists for decades. The hippocampus and surrounding medial-temporal-lobe (MTL) structures are critical for both memory and spatial navigation, yet we do not fully understand the neuronal representations used to support these behaviors. Much research has examined how the MTL neurally represents spatial information, such as with “place cells” that represent an animal’s current location or “head-direction cells” that code for an animal’s current heading. In addition to attending to current spatial locations, navigating to remote destinations is a common part of daily life. In this dissertation I investigate how the human MTL represents the relevant information in a goal-directed spatial-memory task. Specifically, I analyze single-neuron and local field potential (LFP) data from neurosurgical patients with respect to their spatial navigation and memory behavior, with a focus on probing the link between neuronal firing, oscillations, and memory. In Chapter 2, I find that the firing rates of many MTL neurons during navigation significantly change depending on the position of the current spatial target. In addition, I observe neurons whose firing rates during navigation are tuned to specific heading directions in the environment, and others whose activity changes depending on the timing within the trial. By showing that neurons in our task represent remote locations rather than the subject’s own position, my results suggest that the human MTL can represent remote spatial information according to task demands. In Chapter 3, I find that during encoding the left hippocampus exhibits greater low theta power for subsequently recalled items compared to unrecalled items. I also find that high frequency activity and neuronal firing in the hippocampus distinguish between item-filled compared to empty chests. Finally, I find that MTL cells’ firing rates and the differential timing of spikes relative to low frequency oscillations in the LFP distinguish between subsequent recall conditions. These results provide evidence for a distinct processing state during the encoding of successful spatial memory in the human MTL. Overall, in this thesis I show new aspects of the neural code for spatial memories, and how the human MTL supports these representations.

description: We present an investigation of the Rho-meson from Nf=2+1+1 flavour lattice QCD. The calculation is performed based on gauge configuration ensembles produced by the ETM collaboration with three lattice spacing values and pion masses ranging from 230 MeV to 500 MeV. Applying the Lüscher method phase shift curves are determined for all ensembles separately. Assuming a Breit-Wigner form, the Rho-meson mass and width are determined by a fit to these phase shift curves. Mass and width combined are then extrapolated to the chiral limit, while lattice artefacts are not detectable within our statistical uncertainties. For the Rho-meson mass extrapolated to the physical point we find good agreement with experiment. The corresponding decay width differs by about two standard deviations from the experimental value.

description: What makes an innovator famous? This is the principal question of this dissertation. I examine three potential drivers of the innovators’ fame – their social structure, creativity and identity.  My empirical context is the early 20th century abstract artists in 1910-25. The period represents a paradigmatic shift in the history of modern art, the emergence of the abstract art movement. In chapter 2, I operationalize social structure by an innovator’s local peer network. I find that an innovator with structurally and compositionally diverse local network is likely to be more famous than the one with a homogenous local network. I find no statistical evidence for creativity as a link between social structure and fame. Instead, the evidence suggests that an innovator’s creative identity and access to promotional opportunities are the key drivers of her fame. In Chapter 3, I find that the creativity identity resulting from an innovator’s creative trajectory can lead to obscurity despite early fame and acclaim. The drastic change in the nature of a producer’s output can dilute her identity and cost her her niche. In combination with her peer network characteristics, these dynamics can mean obscurity even for talented and prolific innovators. In chapter 4, I undertake a large-scale analysis of the relationship between creativity and fame. Using a novel computational measure for the novelty of the artists’ works, I explore how their creativity and fame evolve over 1905-2000 in five markets. I find no statistical evidence for a positive relationship between creativity and fame; in fact, the statistical evidence is in favor of a negative relationship between creativity and fame through several time periods. The results suggest that creativity (measured by expert or machines) is not a driver of fame. In effect, it further supports the conclusions of chapter 2 and 3.

description: We study a 3-dimensional topological sigma-model, whose target space is a hyper-Kahler manifold X. A Feynman diagram calculation of its partition function demonstrates that it is a finite type invariant of 3-manifolds which is similar in structure to those appearing in the perturbative calculation of the Chern-Simons partition function. The sigma-model suggests a new system of weights for finite type invariants of 3-manifolds, described by trivalent graphs. The Riemann curvature of X plays the role of Lie algebra structure constants in Chern-Simons theory, and the Bianchi identity plays the role of the Jacobi identity in guaranteeing the so-called IHX relation among the weights. We argue that, for special choices of X, the partition function of the sigma-model yields the Casson-Walker invariant and its generalizations. We also derive Walker's surgery formula from the SL(2,Z) action on the finite-dimensional Hilbert space obtained by quantizing the sigma-model on a two-dimensional torus.

Elegies for Empire: The Poetics of Memory in the Late Work of Du Fu (712-770)

Year: 2013
Subjects: Chinese literature

Collective memory

description: This dissertation explores highly influential constructions of the past at a key turning point in Chinese history by mapping out what I term a poetics of memory in the more than four hundred poems written by Du Fu (712-770) during his two-year stay in the remote town of Kuizhou (modern Fengjie). A survivor of the catastrophic An Lushan rebellion (756-763), which transformed Tang Dynasty (618-906) politics and culture, Du Fu was among the first to write in the twilight of the Chinese medieval period. His most prescient anticipation of mid-Tang concerns was his restless preoccupation with memory and its mediations, which drove his prolific output in Kuizhou. For Du Fu, memory held the promise of salvaging and creatively reimagining personal, social, and cultural identities under conditions of displacement and sweeping social change. The poetics of his late work is characterized by an acute attentiveness to the material supports--monuments, rituals, images, and texts--that enabled and structured connections to the past. The organization of the study attempts to capture the range of Du Fu's engagement with memory's frameworks and media. It begins by examining commemorative poems that read Kuizhou's historical memory in local landmarks, decoding and rhetorically emulating great deeds of classical exemplars. The second chapter explores the shifting boundaries Du Fu draws between the customs of Kuizhou's local people and the orthodox ritual practices that defined his identity as a scholar-official. This is followed by an interlude that discusses poems on housework, in which domesticating projects spur reflection on poetry's capacity to create cultural value through commemoration. Chapter three turns to poems on paintings, arguing that for Du Fu painted images served as a vital support for memory of pre-rebellion court society, and that in writing on them he both drew upon and redefined a medieval visual aesthetic of craft and pictorial illusionism. The fourth and final chapter analyzes the rhetoric of narrative autobiographical poems, traditionally approached as non-figurative factual records, in order to elucidate Du Fu's retrospective construction of a self. A picture thus emerges of a body of work in which memory, mediated through material objects and practices, functioned to envision and rebuild frameworks of identity in an age of upheaval and transition. This study will contribute to a more critical understanding of a major poet, of the representation and uses of memory in traditional Chinese poetry, and of the emergence of new forms of expression and literati identity in late medieval China.

description: In recent years, the introduction of knowledge graphs (KGs) has significantly advanced recommender systems by facilitating the discovery of potential associations between items. However, existing methods still face several limitations. First, most KGs suffer from missing facts or limited scopes. Second, existing methods convert textual information in KGs into IDs, resulting in the loss of natural semantic connections between different items. Third, existing methods struggle to capture high-order connections in the global KG. To address these limitations, we propose a novel method called CoLaKG, which leverages large language models (LLMs) to improve KG-based recommendations. The extensive knowledge and remarkable reasoning capabilities of LLMs enable our method to supplement missing facts in KGs, and their powerful text understanding abilities allow for better utilization of semantic information. Specifically, CoLaKG extracts useful information from KGs at both local and global levels. By employing the item-centered subgraph extraction and prompt engineering, it can accurately understand the local information. In addition, through the semantic-based retrieval module, each item is enriched by related items from the entire knowledge graph, effectively harnessing global information. Furthermore, the local and global information are effectively integrated into the recommendation model through a representation fusion module and a retrieval-augmented representation learning module, respectively. Extensive experiments on four real-world datasets demonstrate the superiority of our method.

description: Computer-based psychological interventions have emerged as an efficacious and more accessible alternative to traditional face-to-face mental health services. In recent years, these programs have also begun to feature heavily in the literature and commentary on stepped-cared and sustainable approaches to mental health services globally (Hosie, Vogl, Hoddinott, Carden, & Comeau, 2014). Australia is among those countries leading the way in the research of computer-based therapies, yet even here, these innovative services remain underutilised in the community (Lawrence et al., 2015). We need to think critically around why this is and how we can improve uptake, to improve access to interventions for youth. Understanding consumer attitudes towards these programs is the first step. Literature in this area is developing, particularly among allied health professionals and adult populations, yet children and youth have gained little attention. Following this, the present dissertation sought to provide a detailed and critical look at potential consumer attitudes towards computer-based therapies for young people.

Shadow and deflection angle of rotating black hole in asymptotically safe gravity

description: We analytically investigate the shadows cast by rotating black holes in the asymptotically safe gravity (ASG) by deriving complete null geodesics and observables using the Hamilton-Jacobi equation and Carter separable method. It turns out that the apparent shape and size of the shadow depend on the ASG parameters ($ζ, γ$) in addition to other black hole parameters ($M, a$). The size of black hole shadows monotonically decreases and shadows get more distorted with increasing values of ASG parameters when compared with the Kerr black hole shadows. In turn, we use shadow observables to estimate black hole spin and ASG parameters. Noteworthy, we find that the deflection angle of the light has been modified by ASG parameters to generalize the Kerr deflection angle, and the corrections in the deflection angle are of $\mathcal{O}(μ$as). In the vanishing limits of ASG parameters, our results smoothly reduced to the Kerr black holes. The inferred circularity deviation $ΔC\leq 0.10$ for the M87* black hole shadow merely constrains the ASG parameter $ζ$, however, shadow angular diameter $θ_d=42\pm 3\, μ$as, within the $1σ$ region, places bounds $ζ\leq 0.1324$ for $γ=0.10$.

description: Working memory (WM) is crucial for intelligent cognitive functioning, and synchronization phenomena in the fronto-parietal network have been suggested as an underlying neural mechanism. In an attempt to provide causal evidence for this assumption, we applied transcranial alternating current stimulation (tACS) at theta frequency over fronto-parietal sites during a visuospatial match-to-sample (MtS) task. Depending on the stimulation protocol, i.e., in- phase, anti-phase or sham, we anticipated a differential impact of tACS on behavioral WM performance as well as on the EEG (electroencephalography) during resting state before and after stimulation. We hypothesized that in- phase tACS of the fronto-parietal theta network (stimulation frequency: 5 Hz; intensity: 1 mA peak-to-peak) would result in performance enhancement, whereas anti-phase tACS would cause performance impairment. Eighteen participants (nine female) received in-phase, anti-phase, and sham stimulation in balanced order. While being stimulated, subjects performed the MtS task, which varied in executive demand (two levels: low and high). EEG analysis of power peaks within the delta (0.5–4 Hz), theta (4–8 Hz), alpha (8–12 Hz), and beta (12–30 Hz) frequency bands was carried out. No significant differences were observed between in-phase and anti-phase stimulation regarding both behavioral and EEG measurements. Yet, with regard to the alpha frequency band, we observed a statistically significant drop of peak power from pre to post in the sham condition, whereas alpha power remained on a similar level in the actively stimulated conditions. Our results indicate a frequency-unspecific modulation of neuronal oscillations by tACS. However, the closer participants’ individual theta peak frequencies were to the stimulation frequency of 5 Hz after anti- phase tACS, the faster they responded in the MtS task. This effect did not reach statistical significance during in-phase tACS and was not present during sham. A lack of statistically significant behavioral results in the MtS task and frequency-unspecific effects on the electrophysiological level question the effectiveness of tACS in modulating cortical oscillations in a frequency- specific manner.

description: The zx-calculus and related theories are based on so-called interacting Frobenius algebras, where a pair of dagger-special commutative Frobenius algebras jointly form a pair of Hopf algebras. In this setting we introduce a generalisation of this structure, Hopf-Frobenius algebras, starting from a single Hopf algebra which is not necessarily commutative or cocommutative. We provide a few necessary and sufficient conditions for a Hopf algebra to be a Hopf-Frobenius algebra, and show that every Hopf algebra in the category of finite dimensional vector spaces is a Hopf-Frobenius algebra. In addition, we show that this construction is unique up to an invertible scalar. Due to this fact, Hopf-Frobenius algebras provide two canonical notions of duality, and give us a "dual" Hopf algebra that is isomorphic to the usual dual Hopf algebra in a compact closed category. We use this isomorphism to construct a Hopf algebra isomorphic to the Drinfeld double, but has a much simpler presentation.

description: An understanding of the mechanism for hydrate formation from water-in-oil emulsions is integral for progressing from preventing hydrate formation through expensive thermodynamic means to hydrate blockage prevention. This work presents hydrate formation and agglomeration in a stirred system studied using two complementary particle size analysis techniques, a Particle Video Microscope (PVM) and a Focused Beam Reflectance Measurement (FBRM). The PVM provides qualitative visual information through digital images in the black oil illuminated by a series of lasers. The FBRM provides a quantitative chord length distribution of the particles/droplets in the system. Three sets of experiments were performed using two different Crude oils, Conroe with a very small asphaltene content and poor emulsion stability, and Caratinga with a much higher asphaltene content and emulsion stability. The first experiments looked at ice as an analogy to hydrates, studying the morphology with both the PVM and FBRM. The second experiments looked at the effect of droplet size on hydrate formation and agglomeration, and the third set of experiments studied the dissociation process using a combination of the PVM and in situ conductivity measurements to determine the continuous phase. For hydrate formation, droplet size was found to have a major effect on whether or not agglomeration will occur. During dissociation agglomeration is extremely dramatic due to the creation of surface water on the particles. The dissociation of these agglomerates results in a significant destabilization of the suspension into a water/hydrate phase at the bottom of the cell until dissociation is complete. The dissociation conceptual picture presented illustrates an important implication when operating a flow line with hydrates present; dissociation within the pipeline should be prevented until the hydrates are out of the flow line.

description: The investigation of wavefront sets of n-point distributions in quantum field theory has recently acquired some attention stimulated by results obtained with the help of concepts from microlocal analysis in quantum field theory in curved spacetime. In the present paper, the notion of wavefront set of a distribution is generalized so as to be applicable to states and linear functionals on nets of operator algebras carrying a covariant action of the translation group in arbitrary dimension. In the case where one is given a quantum field theory in the operator algebraic framework, this generalized notion of wavefront set, called "asymptotic correlation spectrum", is further investigated and several of its properties for physical states are derived. We also investigate the connection between the asymptotic correlation spectrum of a physical state and the wavefront sets of the corresponding Wightman distributions if there is a Wightman field affiliated to the local operator algebras. Finally we present a new result (generalizing known facts) which shows that certain spacetime points must be contained in the singular supports of the 2n-point distributions of a non-trivial Wightman field.

Evolution of large-scale perturbations in quintessence models

description: We carry out a comprehensive study of the dynamics of large-scale perturbations in quintessence scenarios. We model the contents of the Universe by a perfect fluid with equation of state w_f and a scalar field Q with potential V(Q). We are able to reduce the perturbation equations to a system of four first-order equations. During each of the five main regimes of quintessence field behaviour, these equations have constant coefficients, enabling analytic solution of the perturbation evolution by eigenvector decomposition. We determine these solutions and discuss their main properties.

description: We consider the reciprocity of the information-theoretic channel of Time Division Duplex (TDD) Multi-User-Multiple Input Multiple Output (MU-MIMO) systems in the up- and downlink. Specifically, we assume that the transmit and receive chains are reciprocal. We take the mutual coupling between the antenna elements at the base station and at the mobiles into account. Mutual coupling influences how to calculate transmit power and noise covariance. The analysis is based on the Multiport Communication Theory, which ensures that the information-theoretic model is consistent with physics. It also includes a detailed noise model. We show that due to the coupling, the information-theoretic up- and downlink channels do not fulfill the ordinary reciprocity relation, even if the input-output relation of the transmit voltage sources and the receive load voltages, i.e., the channel which is estimated with the help of pilot signals in the uplink, is reciprocal. This is a fundamental effect that is not considered otherwise. We show via Monte Carlo simulations that both, using the ordinary reciprocity relation, and not taking the coupling into account, significantly decreases the ergodic rates in single-user and the ergodic sum rates in multi-user systems.
Mirror Symmetry and the Web of Landau-Ginzburg String Vacua

description: We present some mathematical aspects of Landau-Ginzburg string vacua in terms of toric geometry. The one-to-one correspondence between toric divisors and some of (-1,1) states in Landau-Ginzburg model is presented for superpotentials of typical types. The Landau-Ginzburg interpretation of non-toric divisors is also presented. Using this interpretation, we propose a method to solve the so-called "twisted sector problem" by orbifold construction. Moreover,this construction shows that the moduli spaces of the original Landau-Ginzburg string vacua and their orbifolds are connected. By considering the mirror map of Landau-Ginzburg models, we obtain the relation between Mori vectors and the twist operators of our orbifoldization. This consideration enables us to argue the embedding of the Seiberg-Witten curve in the defining equation of the Calabi-Yau manifoulds on which the type II string gets compactified. Related topics concerning the Calabi-Yau fourfolds and the extremal transition are discussed.

 Records from India. ANDHRA PRADESH: Visakhapatnam – Rao & Mohan (1977); GENERAL RECORD: Naidu & Rao (2004).
 Habitat (as in Indian records). Freshwater; among aquatic vegetation.
 Distribution. USA, Europe and India.
 Remarks. The original description is incomplete; however, at a morphological level, the species should be easy to identify due to its small size and the peculiar type and arrangement of the spiny dorsal covering. In fact, it is made of short simple spines on the head, neck, and anterior trunk, and of 20 long, barbed spines, arranged in five rows and 4 columns on the mid- and posterior trunk region. Real (1940) provided information on the shape and size of the scales from which the longer spines originate. In India, the species has been found only once (Rao & Mohan 1977), and the accounted morphology of the specimens fits well with the original description. The subgenus Hystricochaetonotus appears misspelled in the legends of figures 59-64 of Naidu & Rao (2004).

description: Codimension-two bifurcations are fundamental and interesting phenomena in dynamical systems. Fold-Hopf and double-Hopf bifurcations are the most important among them. We study the unfoldings of these two codimension-two bifurcations, and obtain sufficient conditions for their nonintegrability in the meaning of Bogoyavlenskij. We reduce the problems of the unfoldings to those of planar polynomial vector fields and analyze the nonintegrability of the planar vector fields, based on Ayoul and Zung's version of the Morales-Ramis theory. New useful criteria for nonintegrability of planar polynomial vector fields are also given. The approaches used here are applicable to many problems including circular symmetric systems.
