description: The static $B^{*}Bπ$ coupling, $\hat{g}_χ$, a low energy constant in the leading order heavy meson chiral Lagrangian, is determined using $N_\mathrm{f} = 2$ lattice QCD. We use CLS ensembles with lattice spacings and pion masses down to $a = 0.05\mathrm{fm}$ and $m_π=270\mathrm{MeV}$, and perform combined continuum and chiral extrapolations of our results which have a much better accuracy than previous numbers in the literature. As a by-product, we determine the coupling between the first radial excitations in the $B$ and $B^{*}$ channels ($\hat{g}_{22}$). Accounting for all uncertainties, which are dominated by the chiral extrapolation, we obtain $\hat{g}_χ= 0.492(29)$, while $\hat{g}_{22}$ is somewhat smaller. The comparison to a precise quenched computation suggests that there is little influence by the sea quarks and $\hat{g}_χ$ will not change much when a dynamical strange quark is included.

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We consider T-invariant spin currents induced by spin-orbit interactions which originate from the confined motion of spin carriers in nanostructures. The resulting Thomas spin precession is a fundamental and purely kinematic relativistic effect occurring when the acceleration of carriers is not parallel to their velocity. In the case, where the carriers (e.g. electrons) have magnetic moment the forces due to the electric field of the spin current can, in certain conditions, exceed the van der Waals-Casimir forces by several orders of magnitude. We also discuss a possible experimental set-up tailored to use these forces for checking the existence of a nonzero anomalous magnetic moment of the photon.

Alien Flesh: digital subjectivity and electroacoustic composition
Creators: name: Anderson, Natasha
Publisher: name: Monash University
Year: 2023
Subjects: Music composition and improvisation

description: This research project poses the question, given we live in an increasingly digital world, how might the analogue-digital interface of electroacoustic composition, understood as an allegorical device, work to make audible the uncertain ontological status of the digital subject? Explored through both creative praxis and theoretical exegesis, this research project is a speculative, cognitive mapping of the ontologies and techniques of the acoustic-electronic interface. Through Alexander R. Galloway’s notion of the interface effect, and his analysis of digitality and analogicity as historical modes of thought, it investigates the sonic morph as an allegory of hauntological hyper-capitalism. Mark Fisher’s Gothic Materialisms (sonic hauntology, the weird and the eerie, hyperfiction and the flatline) underpin this project’s exploration of the acoustic-electronic sonic interface as a practice whose aesthetics inevitably sound a politics.

Thinking Beyond Consent: Sexual Subjectivities of Heterosexual, Same-Sex Attracted and Queer Young Adults in Australia
Creators: name: SCHOFIELD, KATHERINE ANNE
Publisher: name: Monash University
Year: 2023
Subjects: Crime and social justice

description: Consent is positioned legally as the demarcation between acceptable and unacceptable sexual conduct, yet it is not simply a legal construct. Consent has a plethora of meanings based on social norms and personal values. The implication of these multiple meanings is that what is considered sexual consent, and subsequently what is considered sexual violation, varies according to the individual. Utilising qualitative data obtained from twenty-two semi-structured interviews, this thesis explores how sexual consent is understood by heterosexual, same-sex attracted and queer young adults from across Australia.
The Nature and Mechanisms of Self-censorship: Chinese Citizen Journalism and Its Boundaries

description: This thesis explores self-censorship as a routine practice of citizen journalism in China. Based on two cases, Cenci Journalism Project (参差计划 in Chinese) and #MeToo in China, I investigated the language use in citizen journalistic stories and conducted interviews with practitioners. This research suggests self-censorship is not only consciously practised due to an external censorship regime, but also happens without awareness. This research conceptualises citizen journalism as the public’s participation in social discussion to take on their social responsibilities and recommends not identifying citizen journalism practitioners as journalists. It is because, everyone can do journalism.
title: Groundwater resources in northern Namibia

Publisher: name: Deutsche Geologische Gesellschaft - Geologische Vereinigung e.V. (DGGV)
Year: 2021

description: The transboundary Cuvelai-Etosha Basin (Namibia/ Angola) is a semi-arid region. Rising population and water demand increase the stress on already scarce water resources. The local aquifers, the perched KOH-0 and the deeper KOH-1 are of limited use, the former due to low yields and microbiological issues, the latter due to often brackish water. A previously unknown deep freshwater aquifer, KOH-2, with high yield and good water quality was discovered at the end of the 1990s. This new resource is a game changer for the region. Therefore, the geological framework of the CEB and its hydrogeological conditions were investigated by detailed geological (core drilling), geophysical (TEM) and hydrogeological studies. The geological background of the KOH-2 is an inland mega-fan system, reaching from the Angolan highlands in the north down to the Etosha Pan. A 400 m cored borehole revealed three distinct depositional sequences, which cover the last 60 Ma. The lower Olukonda Formation (270-400 m) has poor well yields due to a high degree of heterogeneity. It is overlain by the Andoni Formation, of which the KOH-2 (170-270 m) forms the lower part. The transition between the formations is marked by distinct geochemical changes, indicating different source areas. The KOH-2 is overlain by a sequence of aquitards and aquifers (KOH-1 (80-110 m), KOH-0). The sedimentology of mega-fans strongly affects the distribution and hydraulic properties of aquifers and aquitards. This knowledge will be useful for the further exploration and sustainable development of the KOH-2.

description: (abridged) We present a new tool for building synthetic colour-magnitude diagrams of coeval stellar populations. We study, from a theoretical point of view, the impact of axial rotation of stars on various observed properties of single-aged stellar populations: magnitude at the turnoff, photometric properties of evolved stars, surface velocities, surface abundances, and the impact of rotation on the age determination of clusters by an isochrone fitting. Stellar models for different initial masses, metallicities, and zero-age main sequence (ZAMS) rotational velocities are used for building interpolated stellar tracks, isochrones, and synthetic clusters for various ages and metallicities. The synthetic populations account for the effects of the initial distribution of the rotational velocities on the ZAMS, the impact of the inclination angle and the effects of gravity and limb darkening, unresolved binaries and photometric errors. Interpolated tracks, isochrones, and synthetic clusters can be computed through a public web interface. For clusters with a metallicity in the range [0.002, 0.014] and an age between 30 Myr and 1 Gyr, the fraction of fast rotators on the main sequence (MS) band is the largest just below the turnoff. This is a natural consequence of the increase in the MS lifetime due to rotation. The fraction of fast rotators one magnitude below the turnoff also increases with the age of the cluster between 30 Myr and 1 Gyr. There is an increase in the fraction of enriched stars when the metallicity decreases. We show that the use of isochrones computed from rotating stellar models with an initial rotation that is representative of the average initial rotation of the stars in clusters provides a reasonable estimate of the age, even though stars in a real cluster did not start their evolution with an identical initial rotation.

description: We study particle dynamics in self-gravitating gaseous discs with a simple cooling law prescription via two-dimensional simulations in the shearing sheet approximation. It is well known that structures arising in the gaseous component of the disc due to a gravitational instability can have a significant effect on the evolution of dust particles. Previous results have shown that spiral density waves can be highly efficient at collecting dust particles, creating significant local over-densities of particles. The degree of such concentrations has been shown to be dependent on two parameters: the size of the dust particles and the rate of gas cooling. We expand on these findings, including the self-gravity of dust particles, to see how these particle over-densities evolve. We use the PENCIL CODE to solve the local shearing sheet equations for gas on a fixed grid together with the equations of motion for solids coupled to the gas through an aerodynamic drag force. We find that the enhancements in the surface density of particles in spiral density wave crests can reach levels high enough to allow the solid component of the disc to collapse under its own self-gravity. This produces many gravitationally bound collections of particles within the spiral structure. The total mass contained in bound structures appears nearly independent of the cooling time, suggesting that the formation of planetesimals through dust particle trapping by self-gravitating density waves may be possible at a larger range of radii within a disc than previously thought. So, density waves due to gravitational instabilities in the early stages of star formation may provide excellent sites for the rapid formation of many large, planetesimal-sized objects.

Bringing Them Home in Australian Life

Subjects: Australian history

description: In 1997, the Bringing Them Home report into Aboriginal child separation was released. Shocking many Australians, the “truth” of its history was soon engulfed in a heated public controversy. Yet for all its impact, the report contained no new historical findings. This thesis suggests that to understand that impact, and the controversy, we need to look beyond the report’s findings to consider how its story was told. Given the current emphasis on “truth telling” as a means to address difficult pasts, Bringing Them Home offers a case study in the consequences of choices made about how to represent the past.
Extended tachyon field using form invariance symmetry

description: In this work we illustrate how form-invariance transformations (FIT) can be used to construct phantom and complementary tachyon cosmologies from standard tachyon field universes. We show how these transformations act on the Hubble expansion rate, the energy density, and pressure of the tachyon field. The FIT generate new cosmologies from a known "seed" one, in particular from the ordinary tachyon field we obtain two types of tachyon species, denominated phantom and complementary tachyon. We see that the FIT allow us to pass from a non-stable cosmology to a stable one and vice-versa, as appeared in the literature. Finally, as an example, we apply the transformations to a cosmological fluid with an inverse square potential, $V \propto ϕ^{-2}$, and generate the extended tachyon field.

description: Calculations are presented for creation of massive and massless scalar particles coupled to Gauss-Bonnet type curvature in Friedmann cosmological models. It has been shown that, for fields of mass~$m$, the effect of the coupling parameter $ζ$ with the Gauss-Bonnet invariant is insignificant if $ζm^2 \ll 1 $. In all cases under consideration, the created particle number is compatible by order of magnitude with the number of causally disconnected space-time regions by the Compton time, corresponding $1/m$ or $\sqrtζ$.

description: This thesis seeks to understand how President Donald Trump’s approach to populist political communication, driven by the use of populist rhetoric and Twitter, enabled him to dominate the 24/7 news cycle during his 2016 presidential election campaign and term in office. Through its examination of President Trump’s tweets and print news coverage of his signature United States-Mexico border wall policy proposal presented as a case study narrative, this thesis argues that President Trump’s populist political communication style was effective in influencing the media agenda surrounding news coverage of the border wall policy.

This equation need not have a solution for every measure $μ$, and we say that $μ$ is a good measure if the Dirichlet problem above admits a solution. We show that for every $μ$ there exists a largest good measure $μ^* \leq μ$. This reduced measure has a number of remarkable properties.

description:

This study investigates written linguistic practices emerging from public debate in Morocco. Although Darija is increasingly used in writing, especially in online platforms, most of its users still stigmatize it. In 2017 the Zakoura Foundation edited the first monolingual dictionary of Darija, a fervently debated initiative. So, this analysis aims to show the limits of such codification initiative, and factors which affect language ideology in Morocco. Therefore, a corpus of articles and readers’ comments on the Zakoura Dictionary of two Moroccan digital newspapers, Goud and Hespress, has been analyzed, quantitively and qualitatively, in order to compare the opinions about language and the language varieties in which they were expressed.

description: Progress in image sensors and computation power has fueled studies to improve acquisition, processing, and analysis of 3D streams along with 3D scenes/objects reconstruction. The role of motion compensation/motion estimation (MCME) in 3D TV from end-to-end user is investigated in this chapter. Motion vectors (MVs) are closely related to the concept of disparities, and they can help improving dynamic scene acquisition, content creation, 2D to 3D conversion, compression coding, decompression/decoding, scene rendering, error concealment, virtual/augmented reality handling, intelligent content retrieval, and displaying. Although there are different 3D shape extraction methods, this chapter focuses mostly on shape-from-motion (SfM) techniques due to their relevance to 3D TV. SfM extraction can restore 3D shape information from a single camera data.

description: The usage of renewable and clean solar energy is expanding at a rapid pace. Applications of thermal energy storage (TES) facility within the solar power ﬁeld enables dispatch ability within the generation of electricity and residential space heating requirements. It helps mitigate the intermittence issue with an energy source like solar power. TES also helps in smoothing out ﬂuctuations in energy demand during diﬀerent time periods of the day. During this paper, a summary of varied solar thermal energy storage materials and thermal energy storage systems that are currently in use is presented. The properties of solar thermal energy storage materials are discussed and analyzed. The dynamic performances of solar thermal energy storage systems in recent investigations are presented and summarized. Storage methods can be classiﬁed into categories according to capacity and discharge time. New developments in solar energy storage require advances in chemical engineering and materials science. Life cycle assessment (LCA) is an important tool to evaluate energy consumption and the environmental impact of renewable energy processes. LCAs of some of the storage methods are reviewed. It is important to note that, while using renewable energy sources such as solar power, storage methods based on non-recyclable materials or methods that consume signiﬁcant amounts of energy may undermine the eﬀort to reduce energy consumption.

description: We introduce a method of measuring a lower limit to the amplitude of surface differential rotation from high-precision, evenly sampled photometric time series. It is applied to main-sequence late-type stars whose optical flux modulation is dominated by starspots. An autocorrelation of the time series was used to select stars that allow an accurate determination of starspot rotation periods. A simple two-spot model was applied together with a Bayesian information criterion to preliminarily select intervals of the time series showing evidence of differential rotation with starspots of almost constant area. Finally, the significance of the differential rotation detection and a measurement of its amplitude and uncertainty were obtained by an a posteriori Bayesian analysis based on a Monte Carlo Markov Chain approach. We applied our method to the Sun and eight other stars for which previous spot modelling had been performed to compare our results with previous ones. We find that autocorrelation is a simple method for selecting stars with a coherent rotational signal that is a prerequisite for successfully measuring differential rotation through spot modelling. For a proper Monte Carlo Markov Chain analysis, it is necessary to take the strong correlations among different parameters that exist in spot modelling into account. For the planet-hosting star Kepler-30, we derive a lower limit to the relative amplitude of the differential rotation of ΔP / P = 0.0523 \pm 0.0016. We confirm that the Sun as a star in the optical passband is not suitable for measuring differential rotation owing to the rapid evolution of its photospheric active regions. In general, our method performs well in comparison to more sophisticated and time-consuming approaches.

Gender and politics

description: This thesis investigates how gendered foreign policy practices reproduce national identity and enable enhanced moral power in international relations. It argues that the gendered foreign policy practices of nation-states are shaped by values pertaining to gender. The study demonstrates how moral power games take place in the international realm as contending national values and gendered foreign policy practices collide. These gendered international practices are analysed through the relational cases of Russia and Sweden operating on a binary moral logic of ‘traditional’/‘feminist’. Using Ukraine as a concrete locale, the thesis interrogates how Russian and Swedish national identities constructed through gendered foreign policy practices are implicated in moral power games.

description: Neural network design has utilized flexible nonlinear processes which can mimic biological systems, but has suffered from a lack of traceability in the resulting network. Graphical probabilistic models ground network design in probabilistic reasoning, but the restrictions reduce the expressive capability of each node making network designs complex. The ability to model coupled random variables using the calculus of nonextensive statistical mechanics provides a neural node design incorporating nonlinear coupling between input states while maintaining the rigor of probabilistic reasoning. A generalization of Bayes rule using the coupled product enables a single node to model correlation between hundreds of random variables. A coupled Markov random field is designed for the inferencing and classification of UCI's MLR 'Multiple Features Data Set' such that thousands of linear correlation parameters can be replaced with a single coupling parameter with just a (3%, 4%) percent reduction in (classification, inference) performance.

We work under the model-independent hypothesis of general flavor mixing in the squark sector, being parametrized by a complete set of dimensionless delta^AB_ij (A,B = L, R; i,j = u, c, t or d, s, b) parameters. The present upper bounds on the most relevant NMFV processes, together with the requirement of compatibility in the choice of the MSSM parameters with the recent LHC and g-2 data, lead to updated constraints on all squark flavor mixing parameters.

This inequality has been applied by Brezis, Marcus, and Ponce to study the existence of solutions of the nonlinear equation $- Δu + g(u) = μ$, where $μ$ is a measure and $g : \mathbb{R} \to \mathbb{R}$ is an increasing continuous function.

description: This thesis presents acoustofluidic techniques to substantially improve the synthesis and delivery of drug-carrying particles. Silicon-based ultrafast acoustofluidic micromixers are developed to control the size and distribution of particles without any chemical additives and at very high throughputs. The capability of the devices is demonstrated through the production of different systems ranging from Asthma drugs to DNA nanoparticles. The second part of the thesis explores on-demand methods for targeted and personalised aerosol drug delivery using a low-cost, disposable microfluidic platform, which can tune the droplet size and distribution on-demand according to the patients’ needs.
Twistor/ambitwistor strings and null-superstrings in spacetime of D=4,10 and 11 dimensions

description: We show that, at the classical level, the recently proposed `ambitwistor string' model is equivalent to the spinor moving frame formulation of null-supersting, which in its turn is equivalent to Siegel's formulation of closed twistor string or to its higher dimensional generalizations. Although the null-(super)string is usually considered as describing the tensionless limit of (super)string, we show that its action can be derived from the spinor moving frame formulation of superstring also in the infinite tension limit. This observation allows us to argue on the absence of critical dimensions and suggests that the (ambi)twistor string based technique(s) to calculate field theory amplitudes can be developed not only in D=10 or 26, but also in D=11 and other dimensions. The D=11 and D=10 twistor strings are described in some details.

description: Exploitation of deep geothermal energy is considered as one of the most efficient renewable energy applications. In this sense, reservoir stimulation is established to extract geothermal energy from EGS (Enhanced Geothermal System) which is highly dependent on its in-situ structural properties: damage/shear zones, faults, fractures, its statistics and characteristics. In more detail, damage zones may behave like a conduit providing preferential pathways for fluid flow in otherwise impermeable rock such as granite or gneiss. To improve the reservoirs’ characteristics frequently hydro-shearing or hydro-fracturing are used. It is imperative to account for the natural heterogeneities of the reservoir particularly with respect to the existing fracture network. In this study, we analyze the pre-stimulation fracture network of the EGS experiments conducted at the Grimsel Test Site, in the Swiss Alps. We use original data acquired at the tunnel wall and in boreholes to constrain a probabilistic 3D model further used for H-M simulations of the enhancement experiments. Fracture analysis include scanline mapping, cluster analysis of the spatial distribution and density plots. Keywords: geostatistics, fracture analysis, DFN modeling, 3D geological modeling, geothermal energy

description: CO2 emissions are a major contributor to greenhouse effects, which led researchers to explore the utilization of it. However, thermodynamic stability of CO2 hinders its reactivity. In this work CO2 polycarbonates were synthesized via the alternate insertion of CO2 into epoxides over heterogeneous catalysts based on zinc cobalt and ferrous. Alternating CO2 polycarbonates represents an attractive method to utilize and store CO2 as they are less energy intensive alternative to phosgene-based polycarbonates. The produced polymer has up to 30 % of its weight comprised of CO2 and remains stable up to 200 C. Copolymerization process was simulated using Aspen Plus

description: About 43 percent of the 2.9 million individuals filing U.S. farm income tax returns in 1970 reported a farm loss. Forty percent of total farm losses were reported by individuals with less than $5,000 in basic income and about 17 percent were reported by those with $25,000 or more. Generally, farm losses became more frequent as basic income rose. Over 90 percent of 1970 farm loss returns had a loss of less than $5,000. Losses of $10,000 or more were reported by about 3 percent. These larger losses were concentrated in two basic income classes--those with negative basic incomes and those with $25,000 or more. Nonfarm income was substantially higher for the farm loss group than for the group reporting farm profits. As expected, farm losses became more important in offsetting nonfarm income as farm size increased. Directly limiting the amount of farm loss that could be used to offset nonfarm income to $10,000 would have affected 3.3 percent of 1970 farm loss returns. With a $20,000 limitation, 1.2 percent of the farm loss returns would have increased tax liabilities. A $30,000 limitation would have affected 0.6 percent of the returns.

description: Das AKG C414 ist jedem Audio-Interessierten ein Begriff und seit seiner Erfindung ein viel eingesetztes Universalmikrofon aus Österreich. In meiner Arbeit beschäftige ich mich mit diesem Mikrofon, seiner Weiterentwicklung und der Frage, ob durch die Globalisierung und den damit zusammenhängenden Verkauf von AKG an Samsung, Wissen, in Hinsicht auf die Mikrofonentwicklung, verloren gegangen ist. Um dieser Frage nachzugehen habe ich mit der Firma Austrian Audio zusammengearbeitet, die sich nach der Auflösung von AKG aus den ehemaligen Mitarbeitern gegründet hat, und es sich zur Aufgabe gemacht hat, den „alten“ AKG-Sound wiederherzustellen und zu verbessern. Mit Unterstützung des Senior Acoustic Engineers von Austrian Audio, Dip.-Ing. Christoph Frank, habe ich Messungen an den Mikrofonen AKG C414 EB (ca. 1970), AKG C414 XLS (ca. 2009), dem Austrian Audio OC818 und einem chinesischen Nachbau des letzteren Mikrofons, durchgeführt und die daraus resultierenden Daten mit den Datenblättern und miteinander verglichen. Um nicht nur datenmäßig das beste Mikrofon zu küren- habe ich zusätzlich einen Hörtest durchgeführt, bei dem die Teilnehmer*innen zwischen diesen 4 Mikrofonen in einem Blindtest entschieden haben, welches für sie am besten klingt. Auch wenn das Hörempfinden eine sehr individuelle Sache ist, haben sich klare Tendenzen im Hörtest ergeben, die in Zusammenhang mit den Messungen gebracht werden können.
description: The AKG C414 is a familiar name to anyone interested in audio and has been a much-used universal microphone from Austria since its invention. In my thesis I explore this microphone, its further development, and the question whether knowledge has been lost in terms of microphone development due to globalization and the related sale of AKG to Samsung. To investigate this question, I worked together with the company Austrian Audio, which was founded after the dissolution of AKG from the former employees and has made it its task to restore and improve the "old" AKG sound. With the support of Austrian Audio's Senior Acoustic Engineer, Dip.-Ing. Christoph Frank, I took measurements on the AKG C414 EB (ca. 1970), AKG C414 XLS (ca. 2009), the Austrian Audio OC818 and a Chinese replica of this last microphone and compared the resulting data with the data sheets and with each other. To not only choose the best microphone in terms of data- I also conducted a listening test in which the participants decided between these 4 microphones in a blind test which one sounded best to them. Even though the hearing sensation is a very individual thing, clear tendencies have emerged in the listening test which can be brought in connection with the measurements.

description: Recent experiments demonstrated generation of spin currents by ultrasound. We can understand this acoustically induced spin pumping in terms of the coupling between magnetization and lattice waves. Here we study the parametric excitation of magnetization by longitudinal acoustic waves and calculate the acoustic threshold power. The induced magnetization dynamics can be detected by the spin pumping into an adjacent normal metal that displays the inverse spin Hall effect.
