title: How to Sell Death and Destruction. Russian Media Coverage of Putin's War in Syria
Creators: name: Osipova, Elena
Publisher: name: University of Kent
Year: 2024

description: This thesis examines the way the Russian media covered the war in Syria from the moment Russia officially joined the armed conflict in September 2015. The Russian government propaganda machine had to invoke all the tools in its possession to cover the Syrian war and come up with new tools catering for modern media demands. The officials had to make sure that only government-approved messages would reach the Russian public. An ambitious goal given the modern media diversity and openness.
An inability of most Russian citizens to obtain any kind of information other than available in the Russian language, as well as virtual destruction of independent media organisations in Russia created a perfect opportunity for the government to control all incoming information a Russian citizen could glean on the topic of the Syrian war. This thesis examines the reasoning behind getting into war in Syria (e.g., the repercussions of the war unleashed in Ukraine in 2014 and failing approval ratings and ambitions of president Putin) and the specific media coverage of the Syrian war.
After the war in Ukraine (2014), which became increasingly unpopular among Russian citizens, the Syrian war became a welcome distraction and a way to prove Russia's special place in the world, Russia's greatness. This thesis examines in depth the tools that were used by Russian media to sell the war in Syria to its citizens, as well as reiterate that Russia is one of the mightiest countries in the world in terms of military power and geopolitical influence. This research finds that exact tools used by this propaganda machine are universal and can be applied on any occasion the public needs to be persuaded to approve aggression.
The main finding of this research is: as chaotic as the media coverage of the Syrian war seemed to an untrained eye, it was, in fact, an incredibly structured, disciplined and ultimately successful propaganda programme, full of strict rules and policies media organisations and journalists had to follow to get the desired result. Not only Putin's ratings correlated with media wins in the coverage of the Syrian 'project,' but the public also itself felt patriotic and righteous in terms of Russia's participation in the Syrian war.
Axionic Instability of Periodic Weyl-Semimetal Superstructures

description: Weyl-semimetal superstructures with a spiraling position of a pair of Weyl nodes of opposite chirality can host a chiral-symmetry preserving Fermi-arc metal state, where the chirality is carried by cylindrical Fermi surfaces, electron- and hole-like depending on the chirality. The Fermi surfaces nest at vanishing momentum separation (zero nesting vector) at the electron-hole-compensation energy because the nesting is topologically protected by vanishing spatial overlap of any pair of equal-momentum opposite-chirality states. In this work we show that the nesting and Coulomb interaction drive a spontaneous chiral symmetry breaking in such a Fermi arc metal, which leads to a dynamical axion insulator state but without breaking translational symmetry (no charge-density-wave order) as in a conventional Weyl semimetal. As for material realization, we discuss magnetically doped Bi$_2$Se$_3$, for which the Weyl-node positions depend on the order of the magnetic dopands. In this case, the axionic condensation can itself stabilize a spiral order of the magnetization, and hence the spiraling node positions, even if the magnetic interaction is intrinsically ferromagnetic.

description: In this work, the direct epoxidation reaction of ethylene to ethylene oxide and the influence of cofeeding halogenated hydrocarbons was investigated. Kinetic investigations were conducted to determine intrinsic parameters using a newly designed and constructed isotherm fixed-bed reactor and a compact profile reactor (CPR), which was used to fit the kinetic parameters from measured concentration and temperature profiles at industrial reaction conditions. Also, the CPR was used to study the mechanism of chlorine moderation of the supported silver catalyst, revealing the competitive adsorption behavior of chlorine and oxygen on the same active sites. A pilot-scale reactor was designed and built to validate the kinetic parameters by a 2D pseudohomogeneous profile simulation.
description: In dieser Arbeit wurde die Reaktion von Ethylen zu Ethylenoxid und der Einfluss von zu dosierten halogenierten Kohlenwasserstoffen untersucht. Zur Bestimmung der kinetischen Parameter wurden kinetische Untersuchungen mit Hilfe eines isothermen Festbettreaktors und eines kompakten Profilreaktors (CPR) durchgeführt, der zur Anpassung der kinetischen Parameter aus gemessenen Konzentrations- und Temperaturprofilen verwendet wurde. Der CPR wurde zur Untersuchung des Mechanismus der Chlorierung des Silberkatalysators verwendet, wobei das konkurrierende Adsorptionsverhalten von Chlor und Sauerstoff deutlich wurde. Ein Reaktor im Pilotmaßstab wurde entwickelt, um die kinetischen Parameter durch eine pseudohomogene 2D-Simulation zu validieren.

description: We study the nonequilibrium dynamics of the Floquet quantum East model (a Trotterized version of the kinetically constrained quantum East spin chain) at its "deterministic point", where evolution is defined in terms of CNOT permutation gates. We solve exactly the thermalization dynamics for a broad class of initial product states by means of "space evolution". We prove: (i) the entanglement of a block of spins grows at most at one-half the maximal speed allowed by locality (i.e., half the speed of dual-unitary circuits); (ii) if the block of spins is initially prepared in a classical configuration, speed of entanglement is a quarter of the maximum; (iii) thermalization to the infinite temperature state is reached exactly in a time that scales with the size of the block.

description: The conventional accretion disk lore is that magnetized turbulence is the principal angular momentum transport process that drives accretion. However, when dynamically important large-scale magnetic fields thread an accretion disk, they can produce mass and angular momentum outflows, known as winds, that also drive accretion. Yet, the relative importance of turbulent and wind-driven angular momentum transport is still poorly understood. To probe this question, we analyze a long-duration ($1.2 \times 10^5 r_{\rm g}/c$) simulation of a rapidly rotating ($a=0.9$) black hole feeding from a thick ($H/r\sim0.3$), adiabatic, magnetically arrested disk (MAD), whose dynamically important magnetic field regulates mass inflow and drives both uncollimated and collimated outflows (i.e., winds and jets, respectively). By carefully disentangling the various angular momentum transport processes within the system, we demonstrate the novel result that disk winds and disk turbulence both extract roughly equal amounts of angular momentum from the disk. We find cumulative angular momentum and mass accretion outflow rates of $\dot{L}\propto r^{0.9}$ and $\dot{M}\propto r^{0.4}$, respectively. This result suggests that understanding both turbulent and laminar stresses is key to understanding the evolution of systems where geometrically thick MADs can occur, such as the hard state of X-ray binaries, low-luminosity active galactic nuclei, some tidal disruption events, and possibly gamma-ray bursts.

Translation of environmental knowledge to policy : bridging the gap between scientists and societal change
Creators: name: Adeseko, Israel
Publisher: name: University of Tasmania
Year: 2024

description: Since the early 2000s, environmental communication research has prioritised effectively translating environmental science for non-experts, favouring participatory models over the deficit model. Nevertheless, gaps remain in translating environmental knowledge through mediated and non-media means in complex socio?political contexts. This thesis asks: how can we understand externalities to effective environmental knowledge translation and engage effectively in places with existing environmental conflicts? Using a place-based approach, this study locates Tasmania as a place with existing environmental conflicts and the 2018-19 Tasmanian bushfire as both a critical discourse moment and teachable moment. The study uses a mixed methods approach that includes quantitative content and discourse analysis, expert interviews, and the direct observation of participants to investigate and develop place-based specialised environmental knowledge translation solutions. Further, it examines the discursive practices of actors, particularly Tasmanian forest and fire scientists in news media at a critical discourse moment. Results show that in the mediated communication following the 2018-19 Tasmanian bushfire, mostly non?scientists gained media visibility and meaning-making power in forest-related scientific discourses because they employed policy-facing discourse strategies. Thus, the 2018-19 Tasmanian bushfire -- rather than being a critical discourse moment for the diffusion of forest knowledge -- was a moment of silence for scientists. This finding provides an important insight into the performative functions of actors’ discursive practices and the ‘honest brokering role’ of Tasmanian forest and fire scientists in mediated communication. Moreover, by characterising the 2018-19 Tasmanian bushfire as a teachable moment and interrogating public narratives of the bushfire, the study identifies a unique framework that illustrates how the Tasmanian public tells bushfire stories and how the framework provides contextual values and behavioural cues in designing environmental knowledge translation strategies. The study also pinpoints two effective approaches for engaging the Tasmanian public in forest and fire science, as well as encouraging them to embrace and use new knowledge for behavioural changes and participation in forest management policy discussions. These approaches are the Participatory Action Research (PAR) paradigm and the TM+ISL approach. The latter approach is novel and combines concepts of teachable moments and informal science learning for effective public engagement and environmental knowledge translation. Overall, the study contributes a unique understanding and practice of environmental knowledge translation – both through mediated and non-media means – in places where environmental conflicts exist.

description: Hallway discussions at SPNHC 2019 in Chicago set in motion a long-discussed collaboration between Arctos and Global Biotic Interactions (GloBI). We have come a long way in the threeyears since, and the number of documented relationships in Arctos that are indexed by GloBI doubled in 2020/2021 to include about 150K specimen-based interaction claims and continues to grow. Nonetheless, there still remain hurdles for both platforms to achieve the goals we have set out for connecting related museum records across collections and documenting their biotic interactions. We will discuss the backgrounds of Arctos and GloBI and how their goals align. Also, we'll explore our shared desire to deepen our collaboration; primarily by extending the digital records managed in Arctos through the interactions resolved in GloBI. We will show how GloBI's ability to index biotic interactions enhances the quality of Arctos' records, improves management features, and adds documentation. By sharing our hands-on experience in extending the reach of our Natural History collections beyond their institutional silos, we hope to inspire discussion in the broader biodiversity data community about how to better integrate the valuable evidence-based knowledge in our collections data. Presented as a poster at the meeting of the Society of Preservation of Natural History Collections (SPNHC) 5-10 June 2022 in Edinburgh, Scotland.

description: For a long time, global fits of the electroweak sector of the standard model (SM) have been used to exploit measurements of electroweak precision observables at lepton colliders (LEP, SLC), together with measurements at hadron colliders (Tevatron, LHC) and accurate theoretical predictions at multi-loop level, to constrain free parameters of the SM, such as the Higgs and top masses. Today, all fundamental SM parameters entering these fits are experimentally determined, including information on the Higgs couplings, and the global fits are used as powerful tools to assess the validity of the theory and to constrain scenarios for new physics. Future measurements at the Large Hadron Collider (LHC) and the International Linear Collider (ILC) promise to improve the experimental precision of key observables used in the fits. This paper presents updated electroweak fit results using the latest NNLO theoretical predictions and prospects for the LHC and ILC. The impact of experimental and theoretical uncertainties is analysed in detail. We compare constraints from the electroweak fit on the Higgs couplings with direct LHC measurements, and we examine present and future prospects of these constraints using a model with modified couplings of the Higgs boson to fermions and bosons.

description: Since the initial patent in 2001, the Magnetic Particle Imaging (MPI) community has been striving to develop an MPI scanner suitable for human applications. Numerous contributions from different research fields, regarding tracer development, reconstruction methods, hardware engineering, and sequence design have been employed in pursuit of this objective. In this work, we introduce and thoroughly characterize an improved head-sized MPI scanner with an emphasis on human safety. The scanner is operated by open-source software that enables scanning, monitoring, analysis, and reconstruction, designed to be handled by end users. Our primary focus is to present all technical components of the scanner, with the ultimate objective to investigate brain perfusion imaging in phantom experiments. We have successfully achieved full 3D single- and multi-contrast imaging capabilities at a frame rate of 4 Hz with sufficient sensitivity and resolution for brain applications. To assess system characterization, we devised sensitivity, resolution, perfusion, and multi-contrast experiments, as well as field measurements and sequence analysis. The acquired images were captured using a clinically approved tracer and suitable magnetic field strengths, while adhering to the established human peripheral nerve stimulation thresholds. This advanced scanner holds potential as a tomographic imager for diagnosing conditions such as ischemic stroke or intracranial hemorrhage in environments lacking electromagnetic shielding. Furthermore, due to its low power consumption it may have the potential to facilitate long-term monitoring within intensive care units for various applications.

description: For many decades, the main source of information on the top-left corner element of the Cabibbo-Kobayashi-Maskawa quark mixing matrix $V_{ud}$ were superallowed nuclear beta decays with an impressive 0.01\% precision. This precision, apart from experimental data, relies on theoretical calculations in which nuclear structure-dependent effects and uncertainties play a prime role. This review is dedicated to a thorough reassessment of all ingredients that enter the extraction of the value of $V_{ud}$ from experimental data. We tried to keep balance between historical retrospect and new developments, many of which occurred in just five past years. They have not yet been reviewed in a complete manner, not least because new results are a-coming. This review aims at filling this gap and offers an in-depth yet accessible summary of all recent developments.

MMM and MMMSynth: Clustering of heterogeneous tabular data, and synthetic data generation

description: We provide new algorithms for two tasks relating to heterogeneous tabular datasets: clustering, and synthetic data generation. Tabular datasets typically consist of heterogeneous data types (numerical, ordinal, categorical) in columns, but may also have hidden cluster structure in their rows: for example, they may be drawn from heterogeneous (geographical, socioeconomic, methodological) sources, such that the outcome variable they describe (such as the presence of a disease) may depend not only on the other variables but on the cluster context. Moreover, sharing of biomedical data is often hindered by patient confidentiality laws, and there is current interest in algorithms to generate synthetic tabular data from real data, for example via deep learning.
 We demonstrate a novel EM-based clustering algorithm, MMM (``Madras Mixture Model''), that outperforms standard algorithms in determining clusters in synthetic heterogeneous data, and recovers structure in real data. Based on this, we demonstrate a synthetic tabular data generation algorithm, MMMsynth, that pre-clusters the input data, and generates cluster-wise synthetic data assuming cluster-specific data distributions for the input columns. We benchmark this algorithm by testing the performance of standard ML algorithms when they are trained on synthetic data and tested on real published datasets. Our synthetic data generation algorithm outperforms other literature tabular-data generators, and approaches the performance of training purely with real data.

description: Unsupervised learning, a branch of machine learning that can operate on unlabelled data, has proven to be a powerful tool for data exploration and discovery in astronomy. As large surveys and new telescopes drive a rapid increase in data size and richness, these techniques offer the promise of discovering new classes of objects and of efficient sorting of data into similar types. However, unsupervised learning techniques generally require feature extraction to derive simple but informative representations of images. In this paper, we explore the use of self-supervised deep learning as a method of automated representation learning. We apply the algorithm Bootstrap Your Own Latent (BYOL) to Galaxy Zoo DECaLS images to obtain a lower dimensional representation of each galaxy, known as features. We briefly validate these features using a small supervised classification problem. We then move on to apply an automated clustering algorithm, demonstrating that this fully unsupervised approach is able to successfully group together galaxies with similar morphology. The same features prove useful for anomaly detection, where we use the framework astronomaly to search for merger candidates. While the focus of this work is on optical images, we also explore the versatility of this technique by applying the exact same approach to a small radio galaxy dataset. This work aims to demonstrate that applying deep representation learning is key to unlocking the potential of unsupervised discovery in future datasets from telescopes such as the Vera C. Rubin Observatory and the Square Kilometre Array.
