title: Farsh-e-Parandeh: Animated Mandalic Carpet Projection: Exploring the Links between Proto-Animation Techniques in Persian Traditional Arts and the Foundation of Animation and Cinema

description: This thesis probes associations between ancient Persian arts, which have a circular or mandalic structure, and the various nineteenth-century optical toys that were vital stages in bringing movement to cinema; and examines if the aesthetic links between them are coincidental or may be the result of a discontinuous historical trajectory. Research findings indicates that ancient items that have been found in archaeological digs from Persia hold a significant clue and may be an important piece of the jigsaw of understanding the antecedents of film and moving image—in particular, animation. This thesis builds on an iconographic analysis of a selection of historical artefacts from Persia and compares and contrasts them with the nineteenth century optical toys such as the zoetrope and phenakistoscope. These theoretical and historical dimensions have been incorporated into the creative practice exploring the above associations creatively and affectively. Farsh-e-Parandeh (roughly translated as ‘Flying Carpet’ from Farsi), as an animated aerial-projected installation —a moving-image version of a traditional Persian carpet— reflects renowned philosopher Attar’s Conference of the Birds (AD 1177) as a reference point for mandalic structures of Persian and Sufi mystical stories. Farsh-e-Parandeh challenges the notion of moving-image production history as a necessarily linear projection. This installation instead constructs an immersive, holistic engagement based on cyclic patterned arrangements that harken back to nineteenthcentury moving image forms of early animations.

description: Fordy and Xenitidis [J. Phys. A: Math. Theor. 50 (2017) 165205] recently proposed a large class of discrete integrable systems which include a number of novel integrable difference equations, from the perspective of $\mathbb{Z}_\mathcal{N}$ graded Lax pairs, without providing solutions. In this paper, we establish the link between the Fordy-Xenitidis discrete systems in coprime case and linear integral equations in certain form, which reveals solution structure of these equations. The bilinear form of the Fordy-Xenitidis integrable difference equations is also presented together with the associated general tau function. Furthermore, the solution structure explains the connections between the Fordy-Xenitidis novel models and the discrete Gel'fand-Dikii hierarchy.

description: En este ensayo se analizan las representaciones sociales de desigualdad entre Estados Unidos y América Central y, por extensión, América Latina tal y como aparecen en los relatos históricos, publicados en Estados Unidos desde la década 1850 y hasta el presente, sobre la guerra que los centroamericanos libraron entre 1855 y 1857 para derrotar al filibustero o mercenario estadounidense William Walker que se apoderó de Nicaragua durante esos años. El trabajo muestra como quienes han escrito sobre este tema en los Estados Unidos, desde la propia época de los acontecimientos y hasta tiempos recientes, han relatado esta guerra dentro de una serie de representaciones que suponen una relación de superioridad e inferioridad entre Estados Unidos y América Central, en términos raciales y culturales, principalmente. Así, el estudio muestra en un caso concreto un proceso de producción y reproducción de representaciones de desigualdad a nivel internacional entre estados y sociedades distintas.

description: The [FeFe]-hydrogenases of bacteria and algae are the most efficient hydrogen conversion catalysts in nature. Their active-site cofactor (H-cluster) comprises a [4Fe–4S] cluster linked to a unique diiron site that binds three carbon monoxide (CO) and two cyanide (CN−) ligands. Understanding microbial hydrogen conversion requires elucidation of the interplay of proton and electron transfer events at the H-cluster. We performed real-time spectroscopy on [FeFe]-hydrogenase protein films under controlled variation of atmospheric gas composition, sample pH, and reductant concentration. Attenuated total reflection Fourier-transform infrared spectroscopy was used to monitor shifts of the CO/CN− vibrational bands in response to redox and protonation changes. Three different [FeFe]-hydrogenases and several protein and cofactor variants were compared, including element and isotopic exchange studies. A protonated equivalent (HoxH) of the oxidized state (Hox) was found, which preferentially accumulated at acidic pH and under reducing conditions. We show that the one- electron reduced state Hred′ represents an intrinsically protonated species. Interestingly, the formation of HoxH and Hred′ was independent of the established proton pathway to the diiron site. Quantum chemical calculations of the respective CO/CN− infrared band patterns favored a cysteine ligand of the [4Fe–4S] cluster as the protonation site in HoxH and Hred′. We propose that proton-coupled electron transfer facilitates reduction of the [4Fe–4S] cluster and prevents premature formation of a hydride at the catalytic diiron site. Our findings imply that protonation events both at the [4Fe–4S] cluster and at the diiron site of the H-cluster are important in the hydrogen conversion reaction of [FeFe]-hydrogenases.

description: We introduce a novel method to constrain the Hubble constant ($H_0$) by combining fast radio bursts (FRBs) and their persistent radio sources (PRSs) through the observationally validated Yang relation, $ L_ν \propto | \mathrm{RM} | $, which links PRS luminosity to the rotation measure (RM) of the associated FRB. Using a mock sample of PRSs, we demonstrate that the Yang relation can help to unravel the degeneracies among $H_0$, baryon density parameter $Ω_b$, and baryon fraction in the intergalactic medium $f_{\mathrm{IGM}}$ in the traditional approach of using dispersion measure only to perform cosmological analyses. Our method employs a two-stage Markov Chain Monte Carlo (MCMC) analysis to constrain $H_0$. Using the available data of six observed PRS systems, we obtain a preliminary constraint of $H_0 = 75 \pm 30~\mathrm{km\,s^{-1}\,Mpc^{-1}}$. We briefly discuss possible refinements of the method by reducing residual degeneracies and systematic uncertainties using future data and physical modeling. Our results indicate that the Yang relation can potentially become a new probe for performing FRB cosmology.

description: Two novel glycosides, apostichoposide A1 (1) and B1 (2), were isolated from the viscera of Chinese sea cucumbers (Apostichopus japonicus, Selenka) collected in the Bohai sea. Both the isolated glycosides were characterized by non-holostane type aglycones having 18(16)-lactone and 7(8)-double bond. Cytotoxic activities of the two compounds were evaluated against three human cancer cell lines. Compound 1 had adequate cytotoxic activity against MGC-803 and PC-3M cell lines. Our results indicated that glycosides present in A. japonicus viscera are an important high value resource for biotechnological applications.

description: Fluorine being not substantially present in the chemistry of living beings is an attractive element in tailoring novel chemical, biophysical, and pharmacokinetic properties of peptides and proteins. The hallmark of ribosome- mediated artificial amino acid incorporation into peptides and proteins is a broad substrate tolerance, which is assumed to rely on the absence of evolutionary pressure for efficient editing of artificial amino acids. We used the well-characterized editing proficient isoleucyl-tRNA synthetase (IleRS) from Escherichia coli to investigate the crosstalk of aminoacylation and editing activities against fluorinated amino acids. We show that translation of trifluoroethylglycine (TfeGly) into proteins is prevented by hydrolysis of TfeGly-tRNAIle in the IleRS post-transfer editing domain. The remarkable observation is that dissociation of TfeGly-tRNAIle from IleRS is significantly slowed down. This finding is in sharp contrast to natural editing reactions by tRNA synthetases wherein fast editing rates for the noncognate substrates are essential to outcompete fast aa-tRNA dissociation rates. Using a post-transfer editing deficient mutant of IleRS (IleRSAla10), we were able to achieve ribosomal incorporation of TfeGly in vivo. Our work expands the knowledge of ribosome-mediated artificial amino acid translation with detailed analysis of natural editing function against an artificial amino acid providing an impulse for further systematic investigations and engineering of the translation and editing of unusual amino acids.

description: Based on optically stimulated luminescence age estimates it has been argued that the Still Bay represents a sudden, short-lived technological innovation dating to about 72–71 kya. Yet, few sites have the stratigraphic integrity and Still Bay point assemblage size to test this assumption. The Wadley deep sounding of Sibudu Cave provides such an opportunity. Here we use fine-grained analyses consisting of technological attributes and morphometric data to explore the retouched point assemblages of Sibudu over a period of more than ten thousand years spanning the Still Bay. Although we found subtle changes through time, we found no evidence of a technological break in retouched point-production strategies since the Wadley early pre-Still Bay at more than 77 kya through to the final Still Bay/early Howiesons Poort dating to 64.7 ± 2.3 kya. We did, however, uncover a potential point-production hiatus at the site and we present testable hypotheses for this phenomenon. We further contextualise the Sibudu assemblages within southern Africa by directly comparing them with those of Hollow Rock Shelter, Umhlatuzana and Apollo 11. Although our results demonstrate both variation and similarities between the different Still Bay assemblages, we could not replicate a previous suggestion regarding technical disconnection between a north-east/south-west axis on the greater landscape.

description: In the last three decades Regional Parliamentary Institutions (RPIs) have experienced a rapid increase and spread across all regions around the globe. They represent a unique parliamentary phenomenon of international affairs that first and foremost exhibits a genuine legitimacy nexus between local constituencies and the international area. This paper builds on this characteristic and elaborates a legitimacy approach that identifies three legitimacy mechanisms that may help to conceptualize the establishment of specific design features of RPIs. To this end, a concise typology of RPIs with two disjunctive criteria – election mode and connection to a parent regional organization – provides the grounds for a systematic analysis of their organizational design. Building on a newly created dataset of 68 globally spread RPIs, the empirical analysis generates two main findings: (1) the rapid increase of RPIs after 1989 is empirically corroborated for all regions and most types of these institutions; (2) two standard applications of the developed legitimacy mechanisms – functional and normative legitimacy arguments – are not significant in explaining the choice of specific design features of RPIs. Therefore, the observed rapid increase and global spread of these institutions provide tentative evidence to support a diffusion analysis of their emergence and design, making the paper call for a more thorough conceptualization of RPIs’ organizational design and processes of inter- dependent decision-making.

description: I examine the origins of the anti-totalitarian collective memory pervading Central and Eastern Europe by tracking the genesis and development of the region’s ubiquitous and state-sponsored memory institutes. I deploy field analysis, prosopography and in-depth interviews to reveal how these hybrid institutes generate a potent anti-communist symbolic repertoire by overseeing alliances and exchanges across political, historiographic and Eurocratic fields. Memory institutes ensure this hegemony fundamentally via two mechanisms: The scientific validation of their activities by way of scholarly co-optation, and its regional legitimation through incursions into European arenas. I conclude that memory institutes are ultimately a key element of post-communist political competition, responsible for creating a durable symbolic advantage for the right’s conservative identity politics.

description: Network epidemics is a ubiquitous model that can represent different phenomena and finds applications in various domains. Among its various characteristics, a fundamental question concerns the time when an epidemic stops propagating. We investigate this characteristic on a SIS epidemic induced by agents that move according to independent continuous time random walks on a finite graph: Agents can either be infected (I) or susceptible (S), and infection occurs when two agents with different epidemic states meet in a node. After a random recovery time, an infected agent returns to state S and can be infected again. The End of Epidemic (EoE) denotes the first time where all agents are in state S, since after this moment no further infections can occur and the epidemic stops. For the case of two agents on edge-transitive graphs, we characterize EoE as a function of the network structure by relating the Laplace transform of EoE to the Laplace transform of the meeting time of two random walks. Interestingly, this analysis shows a separation between the effect of network structure and epidemic dynamics. We then study the asymptotic behavior of EoE (asymptotically in the size of the graph) under different parameter scalings, identifying regimes where EoE converges in distribution to a proper random variable or to infinity. We also highlight the impact of different graph structures on EoE, characterizing it under complete graphs, complete bipartite graphs, and rings.

description: Alkali-activated materials are a low-CO2 alternative for Portland cement in construction. However, one major issue in their use is the poor or varying functionality of the currently available commercial superplasticizers. Especially for one-part (‘just add water’) alkali-activated materials, the number of studies is limited. In this study, one-part alkali-activated mortar was prepared from blast furnace slag by using solid sodium hydroxide as an activator and microsilica as an additional silica source. Comparison of commonly used superplasticizer types revealed that lignosulfonate, melamine, and naphthalene-based superplasticizers are more efficient than the currently most used polyacrylate and polycarboxylate-superplasticizers. Lignosulfonate-based superplasticizer was overall best-performing: it improved significantly the workability (+41% spread, −51% yield stress, −27% viscosity), setting time (+70%), and compressive strength (+19%) at a 0.5 wt% dose. When the amount of water and superplasticizer were optimized, compressive strength of mortar could be doubled (from 19 to 40 MPa at 28 d).

description: We analyze the hydrodynamic behavior of the porous medium model in a discrete space $\{0,\ldots, n\}$, where the sites $0$ and $n$ stand for reservoirs. Our strategy relies on the entropy method of Guo, Papanicolau and Varadhan. However, this method cannot be straightforwardly applied, since there are configurations that do not evolve according to the dynamics (blocked configurations). In order to avoid this problem, we slightly perturbed the dynamics in such a way that the macroscopic behavior of the system keeps following the porous medium equation, but with boundary conditions which depend on the reservoirs strength's.

description: Background: The potential impact of disease management to optimize quality of care, health outcomes, and total healthcare costs across a range of cardiac disease states is unknown. Methods: A trial-based cost-utility analysis was conducted alongside a randomized controlled trial of 335 patients with chronic, non-valvular AF (without heart failure; the SAFETY Trial) discharged to home from three tertiary referral hospitals in Australia. A home-based disease management intervention (the SAFETY intervention) that involved community-based AF care including home visits was compared to routine primary healthcare and hospital outpatient follow-up (standard management). Bootstrapped incremental cost-utility ratios were computed based on quality-adjusted life-years (QALYs) and total healthcare costs. Cost-effectiveness acceptability curves were constructed to explore the probability of the SAFETY intervention being cost-effective. Sub-group analyses were performed based on age and sex to determine differential cost-effectiveness. Results: During median follow-up of 1.75 years, the SAFETY intervention was associated with a non-statistically significant increase in QALYs (0.02 per person) and lower total healthcare costs (–$4,375 per person). Although each of these findings were not statistically significant, the SAFETY intervention was found to be dominant (more effective and cost saving) in 58.8% of the bootstrapped iterations and cost-effective (more effective and gains in QALYs achieved at or below $50,000 per QALY gained) in 61.5% of the iterations. Males and those aged less than 78 years achieved greater gains in QALYs and savings in healthcare costs. The estimated value of perfect information in Australia (the monetized value of removing uncertainty in the cost-effectiveness results) was A$51 million, thus demonstrating the high potential gain from further research. Conclusions: Compared with standard management, the SAFETY intervention is potentially a dominant strategy for those with chronic, non-valvular AF. However, there would be substantial value in reducing the uncertainty in these estimates from further research.

description: Social marketing has been shown to be an effective approach in assisting people to quit smoking in a wide variety of contexts; including whole communities, segments of society, or entire populations (Stead et al., 2007). The anti-tobacco efforts in Australia have helped to lower tobacco consumption with annual declines in smoking rates across the entire population decreasing year on year (Australian Institute of Health and Welfare, 2014). However, anti-tobacco interventions have been broadly focused on the general Australian population, of which the dominant majority are English speakers, and differences among population sub groups have largely been ignored. As a result, smoking rates within Australia’s culturally and linguistically diverse (CALD) population remain high when compared to general population (Baker et al., 2006). Smoking quit rates have not declined at the same general rates as the rest of the Australian population with variations based on country of birth clearly apparent (Scollo & Winstanley, 2012). Consequently, this thesis aimed to examine how social marketing could be more effectively applied to Australia’s CALD communities.

description: Community and participatory engagement processes have received heightened attention on the political agenda with an increasing number of scholars and practitioners viewing them as a key component in robust, democratic decision-making. These participatory practices are, however, far from perfect. In order to refine and strengthen these imperfect practices it is first necessary to understand in detail how they work. This thesis uses a case study of the Gold Coast Waterfuture Strategy, a participatory engagement process held on the Gold Coast, Queensland, Australia in 2004 and 2005 to focus on two elements that can strengthen or undermine participatory engagement processes. These two key elements are power and trust. This thesis argues, following a networked theory of power that a variety of different modalities of power are exercised during participatory engagement processes, with some of these power modalities contributing to strong trust relationships. Other modalities of power, however, undermine trust relationships. Understanding how these modalities of power undermine or strengthen trust is an important contribution to strengthening participatory engagement processes overall. In dissecting the Gold Coast Waterfuture Strategy Community Advisory Committee process in detail through the lens of specific modalities of power, several key outcomes came to light. First, when individual modalities of power are investigated, it was discovered that participants in the Gold Coast Waterfuture Strategy seemed able to selectively target their trust to deserving individuals or institutions. Second, not all negative modalities of power automatically engender distrust, nor do all positive modalities of power automatically engender trust. Third, the importance of context has been highlighted. It is truly a key issue that needs to replace blanket, universal institutions in many cases. Fourth, there are different mechanisms at play between expert planning and policy systems and participatory planning and policy-making. These mechanisms appear to be able to allow participants to selectively trust or distrust rather than have a general distrust of processes.

description: We derive the exact value of intersection exponents between planar Brownian motions or random walks, confirming predictions from theoretical physics by Duplantier and Kwon. Let B and B' be independent Brownian motions (or simple random walks) in the plane, started from distinct points. We prove that the probability that the paths B[0,t] and B'[0,t] do not intersect decays like t^{-5/8}. More precisely, there is a constant c>0 such that if |B(0) - B'(0)| =1, for all t \ge 1, c^{-1} t^{-5/8} \le ¶[ B[0,t] \cap B'[0,t] = \emptyset ] \le c t^{-5/8}. One consequence is that the set of cut-points of B[0,1] has Hausdorff dimension 3/4 almost surely. The values of other exponents are also derived. Using an analyticity result, which is to be established in a forthcoming paper, it follows that the Hausdorff dimension of the outer boundary of B[0,1] is 4/3, as conjectured by Mandelbrot. The proofs are based on a study of SLE_6 (stochastic Loewner evolution with parameter 6), a recently discovered process which conjecturally is the scaling limit of critical percolation cluster boundaries. The exponents of SLE_6 are calculated, and they agree with the physicists' predictions for the exponents for critical percolation and self-avoiding walks. From the SLE_6 exponents the Brownian intersection exponents are then derived.

description: This paper considers model averaging for the ordered probit and nested logit models, which are widely used in empirical research. Within the frameworks of these models, we examine a range of model averaging methods, including the jackknife method, which is proved to have an optimal asymptotic property in this paper. We conduct a large-scale simulation study to examine the behaviour of these model averaging estimators in finite samples, and draw comparisons with model selection estimators. Our results show that while neither averaging nor selection is a consistently better strategy, model selection results in the poorest estimates far more frequently than averaging, and more often than not, averaging yields superior estimates. Among the averaging methods considered, the one based on a smoothed version of the Bayesian Information criterion frequently produces the most accurate estimates. In three real data applications, we demonstrate the usefulness of model averaging in mitigating problems associated with the ‘replication crisis’ that commonly arises with model selection.

description: Quantum supermaps are a higher-order generalization of quantum maps, taking quantum maps to quantum maps. It is known that any completely positive, trace non-increasing (CPTNI) map can be performed as part of a quantum measurement. By providing an explicit counterexample we show that, instead, not every quantum supermap sending a quantum channel to a CPTNI map can be realized in a measurement on quantum channels. We find that the supermaps that can be implemented in this way are exactly those transforming quantum channels into CPTNI maps even when tensored with the identity supermap. We link this result to the fact that the principle of causality fails in the theory of quantum supermaps.

description: Economic and social stability across the world is tightly dependent on a sufficient and reliable flow of goods and services, based on the balance between supply and demand. The basis for the balance between supply and demand is a set of physical assets, processes and organisations that are collectively known as critical infrastructure systems (CIs). CIs are strongly interdependent in two complex ways: namely, physical and informational. Identification of CI interdependencies and interconnections is essential for the study of such supply and demand systems. Importantly, CI interdependencies and interconnections are also essential for the development of models that help in the study of the impact of extreme events or disasters, or prediction of economic loss from damage caused by cascading impacts on the supply and demand chain system. Based on the stated problem, the aims of this research can be summarized as an estimation of economic loss. This estimation includes individual industry loss and total economic loss, taking interconnected industries into consideration. The main aims are to develop and test a new model and to develop a methodology based on this model for the assessment and management of risk from extreme events on critical infrastructure systems.

description: Momentous events in Western democracies have brought renewed attention to how various aspects of government-controlled policy outputs and outcomes affect citizens’ trust in politics. Unlike most previous research, this study uses individual-level panel data to test the link between government performance evaluations and political trust. Moreover, it gauges performance in more policy areas than previous research, including key aspects of government-controlled social services as well as a wide range of economic risks. The study finds that evaluations of government performance affect political trust but that the evidence is stronger for evaluations of social protection than for economic risks. Crucially, the analysis suggests that the relationship between performance evaluations and distrust is reciprocal. The relationship may be described as a ‘downbound spiral’ where dissatisfied groups develop distrust, which in turn makes for a more pessimistic interpretation of economic risks and welfare state performance.

description: The foundation for the theory of correlation functions of exactly solvable models is determinant representation. Determinant representation permit to describe correlation functions by classical completely integrable differential equations [Barough, McCoy, Wu]. In this paper we show that determinant represents works not only for free fermionic models. We obtained determinant representation for the correlation function $$ of the quantum nonlinear Schrödinger equation, out of free fermionic point. In the forthcoming publications we shall derive completely integrable equation and asymptotic for the quantum correlation function of this model of interacting fermions.

On Perfect, MultiPerfect and Harmonic Numbers.

description: This paper introduces a relative of perfect, multiperfect and harmonic numbers. Call ``\textit{alpha number}", (denote by $@_n$) any positive integer $n$ satisfying $\sigma(n)=(\alpha_1/\alpha_2)n $ with $\alpha_1,\alpha_2$ integers and $\alpha_1\leq \tau (n)$, where $\tau (n)$ is the number of factors of $n$, and $\sigma(n)$ is the sum of divisors function of $n$. We conjecture that there is no odd alpha number above 1, which implies that there is no odd perfect, multiperfect or harmonic number. In this paper, we also provide a form for those numbers, and remark that this form can be improved towards solving the conjectures of this paper.

description: Learning in Deep Neural Networks (DNN) takes place by minimizing a non-convex high-dimensional loss function, typically by a stochastic gradient descent (SGD) strategy. The learning process is observed to be able to find good minimizers without getting stuck in local critical points, and that such minimizers are often satisfactory at avoiding overfitting. How these two features can be kept under control in nonlinear devices composed of millions of tunable connections is a profound and far reaching open question. In this paper we study basic non-convex one- and two-layer neural network models which learn random patterns, and derive a number of basic geometrical and algorithmic features which suggest some answers. We first show that the error loss function presents few extremely wide flat minima (WFM) which coexist with narrower minima and critical points. We then show that the minimizers of the cross-entropy loss function overlap with the WFM of the error loss. We also show examples of learning devices for which WFM do not exist. From the algorithmic perspective we derive entropy driven greedy and message passing algorithms which focus their search on wide flat regions of minimizers. In the case of SGD and cross-entropy loss, we show that a slow reduction of the norm of the weights along the learning process also leads to WFM. We corroborate the results by a numerical study of the correlations between the volumes of the minimizers, their Hessian and their generalization performance on real data.
