title: Experimental optimization of drilling, rock strength and backfilling for mining by drilling applications
Creators: name: Quan, Weizhou
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: A comprehensive study has been conducted to study rock characterizations, drilling performance through drill-off-test (DOT), optimization of cemented tailings backfill (CTB), and investigation of anti-washout property for CTB. The mechanical strengths and ultrasonic velocity of granite, representing high strength of natural isotropic rock, and rock like material (RLM), representing high strength synthetic isotropic rock, were determined in the laboratory. Empirical equations have been developed between these parameters. A novel strength testing method named mono UCS-PLI test was proposed to reduce limitations and strictness of the conventional standard strength tests. Then, the drilling rate of penetration (ROP) as main function of drilling performance was evaluated through two different drill bit types, including roller cone (RC) bit and polycrystalline diamond compact (PDC) bit. Sandstone was used as the testing rock, representing a tight and low permeability isotropic formation. A fully instrumented laboratory scale drilling simulator was used for drilling experiments. Weight on bit (WOB), rotary speed (rpm) and water flow rate (FR) were monitored and recorded. The drilling performance was evaluated based on drilling parameters and drill bit type. Besides, investigations of the use of lower binder proportions and optimization of backfill strength development were conducted because of the relatively high cost of Portland cement. The optimization work studied the effects of lower binder proportions (2 wt.% and 4 wt.% by solids mass) and internal vibration on the designed CTB density and mechanical strength development. An extra 10.9% tailings can be placed into extracted wellbore when the CTB is fully vibrated. This behaviour allows more tailings to be securely placed underground and further reduces the surface tailings impoundment requirements and the costs of tailings disposal for the mining industry. The first design of cemented tailings backfill preparation system is a batch system based on many technical experiences from those successful operations. Finally, an anti-washout admixture was found to achieve the anti-washout property of the designed CTB, which can prevent the CTB from being affected by the water during placement.
Sex-Specific Biology of Plasmodium falciparum
Creators: name: Ridgway, Melanie
Publisher: name: The Australian National University
Year: 2019

description: Malaria, caused by Plasmodium parasites, is responsible for almost 500,000 deaths annually. Disease transmission requires the parasite to differentiate into male and female gametocytes in human red blood cells prior to sexual reproduction upon ingestion by a mosquito. This thesis addresses fundamental questions about the sex-specific development of Plasmodium gametocytes to guide transmission-blocking antimalarial interventions. Although Plasmodium depends on host nutrients to survive, the lifecycle of the malaria parasite spans radically different host environments, particularly in terms of lipid composition. In culture, asexual P. falciparum proliferation is accompanied by stage-specific lipid modifications such as increasing phosphatidylcholine during membrane biogenesis. In vivo P. berghei lifecycle progression in the mouse and mosquito is accompanied by changes in lipid composition, with gametocytes apparently synthesising lipids de novo in preparation for transmission. Parasite species-specific lipid changes to the host red blood cell reflect differences in the lipid composition of their respective host species, suggesting host-parasite co-evolution of lipid metabolism. Investigation of gametocyte biology in a sex-specific manner required the development of a novel method to sort male and female gametocytes. The technique is applied to validate novel sex-specific gametocyte markers. The role of DNA methylation in sex determination and differentiation in P. falciparum is also investigated as a fundamental biology application of this technique. Lipid metabolism of P. falciparum gametocytes is next investigated in a sex-specific manner. Female gametocytes stockpile neutral lipids and sphingolipids, consistent with female gametocytes being the main contributor of resources for zygote development immediately after fertilisation. Specific lipids appear to be imported from the host and may be essential culture medium supplements for gametocytes. Finally, the biological significance of de novo synthesis of key sex-specific gametocyte lipids is investigated by genetic and chemical inhibition of parasite lipid metabolism. Overall this thesis highlights gametocyte and sex-specific Plasmodium traits that could assist with monitoring and blocking malaria transmission.

description: Parker Solar Probe (PSP) is the first spacecraft to dive deep into the solar corona, making the first-ever direct measurements of the plasma within the corona and offering unprecedented observations of solar wind plasma in its nascent form. In their journey outward from the Sun, the streams that make up solar wind plasmas interact, expand, and evolve in a number of different ways. Previous theoretical work has shown that coulomb collisions are one of the many factors that dictate the thermodynamic properties that distinguish different kinds of solar wind. Plasma instruments onboard the PSP spacecraft, making up the Solar Wind Electrons, Alphas, and Protons (SWEAP) suite, provide an opportunity to further test and investigate this well-known collisional hypothesis by identifying solar wind plasma streams that are also measured by other spacecraft such as Solar Orbiter and Wind during suitable conjunctions. These multi-point observations will be compared to collisional predictions to evaluate the evolution of plasma distributions as they travel through the inner heliosphere. This work examines the degree to which collisional transport can explain the radial evolution of plasma parameters within 1 au.

description: Objective. The distribution of equal states (DES) quantifies amplitude fluctuations in biomedical signals. However, under certain conditions, such as a high resolution of data collection or special signal processing techniques, equal states may be very rare, whereupon the DES fails to measure the amplitude fluctuations. Approach. To address this problem, we develop a novel threshold DES (tDES) that measures the distribution of differential states within a threshold. To evaluate the proposed tDES, we first analyze five sets of synthetic signals generated in different frequency bands. We then analyze sleep electroencephalography (EEG) datasets taken from the public PhysioNet. Main results. Synthetic signals and detrend-filtered sleep EEGs have no neighboring equal values; however, tDES can effectively measure the amplitude fluctuations within these data. The tDES of EEG data increases significantly as the sleep stage increases, even with datasets covering very short periods, indicating decreased amplitude fluctuations in sleep EEGs. Generally speaking, the presence of more low-frequency components in a physiological series reflects smaller amplitude fluctuations and larger DES. Significance.The tDES provides a reliable computing method for quantifying amplitude fluctuations, exhibiting the characteristics of conceptual simplicity and computational robustness. Our findings broaden the application of quantitative amplitude fluctuations and contribute to the classification of sleep stages based on EEG data.

description: Properly coordinating cooperation is relevant for resolving public good problems such as clean energy and environmental protection. However, little is known about how individuals can coordinate themselves for a certain level of cooperation in large populations of strangers. In a typical situation, a consensus-building process hardly succeeds due to lack of face and standing. The evolution of cooperation in this type of situation is studied using threshold public good games in which cooperation prevails when it is initially sufficient, or otherwise, it perishes. While punishment is a powerful tool to shape human behaviours, institutional punishment is often too costly to start with only a few contributors, which is another coordination problem. Here we show that whatever the initial conditions, reward funds based on voluntary contribution can evolve. The voluntary reward paves the way for effectively overcoming the coordination problem and efficiently transforms freeloaders to cooperators with a perceived small risk of collective failure.

description: We reconsider thermal production of axions in the early universe, including axion couplings to all Standard Model (SM) particles. Concerning the axion coupling to gluons, we find that thermal effects enhance the axion production rate by a factor of few with respect to previous computations performed in the limit of small strong gauge coupling. Furthermore, we find that the top Yukawa coupling induces a much larger axion production rate, unless the axion couples to SM particles only via anomalies.

Diels-Alder Reactions in Multi-Ring Forming Processes
Creators: name: Shadwell, Natalie
Publisher: name: The Australian National University
Year: 2021

description: The Diels-Alder reaction is one of the most powerful reactions available to the synthetic organic chemist. Its greatest strength is its ability to generate the most prevalent cyclic system, namely the six-membered ring, in one synthetic operation from a versatile array of substrates. This thesis explores the application of the Diels-Alder reaction to multi-ring forming processes. Chapter 1 - By way of introduction, the first chapter provides a brief commentary on the pursuit of efficiency in synthetic organic chemistry and, as a matter of course, the power of the Diels-Alder reaction as a multi-bond forming process. As a preamble, it signposts these important themes, which have driven the investigations conducted in this thesis. Chapter 2 - The second chapter encapsulates two separate pieces of synthetic work. Firstly, the diene-transmissive twofold Diels-Alder reaction sequence of [3]dendralene with relatively un-activated cyclic dienophiles is developed. This methodology permits access to a diverse array of polycyclic structures, with twenty structurally distinct tetracyclic frameworks prepared. Secondly, Chapter 2 reports the application of this methodology to the concise enantioselective synthesis of the popular synthetic target and biologically-important marine natural product, (+)-xestoquinone. Notably, this work a) constitutes the first application of the parent [3]dendralene in total synthesis; and b) constructs three out of the four carbocyclic rings of the natural product via a Diels-Alder reaction, resulting in the shortest preparation of the molecule to date. This work is presented as a journal article draft for submission to Science. Chapter 3 - In the third chapter, the pentacyclic marine natural products, (+)-xestoquinone and (+)-halenaquinone are introduced in detail. Previous syntheses of these natural products as well as structurally similar compounds are comprehensively and systematically reviewed to place the preceding synthetic work (Chapter 2) in context. Chapter 4 - In Chapter Four, the diene-transmissive Diels-Alder reaction sequence of parent and substituted [3]dendralenes is developed to use enantiomerically pure, readily available, cyclic dienophiles for the first time. This methodology builds upon the key Diels-Alder reaction sequence reported in the synthesis of (+)-xestoquinone (Chapter 2) and enables the rapid synthesis of a range of chiral polycyclic frameworks in enantiopure form. Chapter 5 - Chapter Five reviews the development and application of the intramolecular Diels-Alder reaction to total synthesis and takes the form of an invited journal article drafted for publication in Angewandte Chemie. The application of the Diels-Alder reaction to multi- ring forming events is explored from a different perspective to that examined throughout the rest of this thesis.

description: The inverse stellar structure problem determines the equation of state of the matter in stars from a knowledge of their macroscopic observables (e.g. their masses and radii). This problem was solved in a previous paper by constructing a spectral representation of the equation of state whose stellar models match a prescribed set of macroscopic observables. This paper improves and extends that work in two significant ways: i) The method is made more robust by accounting for an unexpected feature of the enthalpy based representations of the equations of state used in this work. After making the appropriate modifications, accurate initial guesses for the spectral parameters are no longer needed so Monte-Carlo techniques can now be used to ensure the best fit to the observables. ii) The method is extended here to use masses and tidal deformabilities (which will be measured by gravitational wave observations of neutron-star mergers) as the macroscopic observables instead of masses and radii. The accuracy and reliability of this extended and more robust spectral method is evaluated in this paper using mock data for observables from stars based on 34 different theoretical models of the high density neutron-star equation of state. In qualitative agreement with earlier work, these tests suggest the high density part of the neutron-star equation of state could be determined at the few-percent accuracy level using high quality measurements of the masses and radii (or masses and tidal deformabilities) of just two or three neutron stars.

description: The redshifts of ~250000 galaxies are used to study the Local Hole and its associated peculiar velocities. The sample, compiled from 6dFGS and SDSS provides wide sky coverage to a depth of ~300h-1Mpc. We have therefore examined K and r limited galaxy redshift distributions and number counts to map the local density field. Comparing observed galaxy n(z) distributions to homogeneous models in three large regions of the high latitude sky, we find evidence for under-densities ranging from ~4-40% in these regions to depths of ~150h-1Mpc with the deepest under-density being over the Southern Galactic cap. Using the Galaxy and Mass Assembly (GAMA) survey we then establish the normalisation of galaxy counts at fainter magnitudes and thus confirm that the underdensity over all three fields at K<12.5 is ~15+-3%. Finally, we further use redshift catalogues to map peculiar velocities over the same areas using the average redshift - magnitude, zbar(m), technique of Soneira (1979). After accounting for the direct effect of large-scale structure on zbar(m) we can then search for peculiar velocities. Taking all three regions into consideration the data reject at the ~4sigma level the idea that we have recovered the CMB rest frame in the volume probed. There is therefore some consistent evidence from counts and Hubble diagram for a local ~150h-1Mpc underdensity that deeper counts and redshifts in the Northern Galactic cap suggest may extend to ~300h-1Mpc.

Designing and Modelling of Nanostructures for Plasmonically Enhanced Hot-Electron Devices
Creators: name: Dolati, Noushin
Publisher: name: The Australian National University
Year: 2021

description: Plasmonically Enhanced Hot-Electron (PEH) devices are a new category of optoelectronic devices based on the excitation of hot electrons over a metal-semiconductor junction. Due to their spectral tunability, PEH devices have attracted interest for applications such as tailored photodetection, solar energy conversion, photocatalysis and water splitting. The efficiency of PEH devices depends on the absorption of incident photons in metal nanostructures, generation of hot-electrons and collection of them by injection over the Schottky junction. The internal quantum efficiency (IQE) of PEH devices is typically limited to a few percent on resonance. Theoretical work has shown that the rate of hot electron generation is dependent on the size of the metal nanoparticles (NPs). Metal NPs with diameters less than 10 nm have the highest generation rates, which could mitigate the low IQE of hot-electron devices. However, arrays of small NPs have limited absorption, and the resonant wavelength cannot be easily tuned. In this thesis, I demonstrate optical methods to optimize and control the absorption in small NPs. I design dual-scale plasmonic nanostructures, including large-scale Au gratings that can optimize the absorption and small-scale Au NPs that can increase the generation of hot-electrons in PEH devices. This research aims to demonstrate strong, tunable absorption in Au NPs to enhance the performance of PEH devices. Using 2D optical modelling, I investigate the effect of the coupling between different resonant modes of gratings and localised surface plasmons in Au NPs. I show that the wavelength and strength of the resonances can be tuned in small NPs absorption in the visible and infrared spectral regions. Furthermore, I demonstrate that introducing a dielectric layer between the NPs and the gratings can increase the absorption in the NPs up to 3.8-fold. These preliminary designs are a promising method to increase absorption in small NPs and achieve the tunability in absorption spectra for application in high-efficiency PEH devices in the future.

Hybrid integration towards single-chip Brillouin devices
Creators: name: Lai, Choon Kong
Publisher: name: The Australian National University
Year: 2021

description: On-chip RF signal processing and generation via the stimulated Brillouin scattering (SBS) process have become significant research topics in the past few years due to their unmatched capabilities. Having access to gigahertz repetition rates can enable applications such as RF filters, true time delay (TTD), optoelectronic oscillator (OEO), and optical frequency comb (OFC). Chalcogenide glass, and in particularly Arsenic Trisulfide, has become a popular optical material due to its high optical nonlinearity, near ideal acoustic properties for SBS applications. However, monolithic integration cannot be realised using chalcogenide glass due to its high propagation loss, fibre-to-chip coupling loss, and facet reflection. In this thesis, a hybrid waveguide solution will be proposed by leveraging the vertical taper technology via shadow mask deposition. By overlaying the Brillouin active waveguide on a low loss versatile germanosilicate platform, a variety of linear functionalities such as ring resonators, Bragg gratings and tolerant couplers can be incorporated in a fully integrated Brillouin based device. The optimisation process for flame hydrolysis deposition of the 3% index contrast germanosilicate and its facet machining have been rigorously studied in this work. This has led to an experimental propagation loss and fibre-to-chip coupling loss of <0.1 dB/cm and 0.2 dB/facet when coupled with a Nufern UHNA-3 fibre. Further, whilst the 0.7 nm/W Brillouin gain coefficient obtained in the proposed hybrid arsenic trisulfide - germanosilicate waveguide is identical to the previous monolithic arsenic trisulfide counterpart, the hybrid structure offers an extra 20 dB reduction in the pump back reflection, making it so suitable to be implemented in the backward SBS applications.

description: Academic tabular benchmarks often contain small sets of curated features. In contrast, data scientists typically collect as many features as possible into their datasets, and even engineer new features from existing ones. To prevent overfitting in subsequent downstream modeling, practitioners commonly use automated feature selection methods that identify a reduced subset of informative features. Existing benchmarks for tabular feature selection consider classical downstream models, toy synthetic datasets, or do not evaluate feature selectors on the basis of downstream performance. Motivated by the increasing popularity of tabular deep learning, we construct a challenging feature selection benchmark evaluated on downstream neural networks including transformers, using real datasets and multiple methods for generating extraneous features. We also propose an input-gradient-based analogue of Lasso for neural networks that outperforms classical feature selection methods on challenging problems such as selecting from corrupted or second-order features.
Trustworthiness as a virtue

Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Starting from the commonplace intuition that trustworthiness is both a trait of character and a morally praiseworthy quality, this thesis defends the position that trustworthiness is a virtue. In doing so, I show that virtue theory not only provides a viable framework for making sense of the claim that we ought to be trustworthy but moreover furnishes a uniquely rich understanding of those qualities that make us worthy of trust. Drawing attention to the idea that trustworthiness is a complex disposition that trades on acquiring a range of both moral and epistemic excellences, I proceed by arguing that these two facets of virtue theory closely track the competence and commitment conditions of trustworthiness. Thereafter, and in order to make sense of how these various elements come together in the character of the trustworthy individual, I develop an analogy between discretion and phronesis and submit that it is in virtue of discretion that a would-be trustee becomes virtuously trustworthy. In closing, I consider several implications of the situationist critique and conclude that despite the ostensibly overwhelming challenge presented by situationism, virtue theory continues to provide a viable framework for normatively rich and explanatorily powerful accounts of those qualities that make us worthy of trust.
N$_2$ accretion, metamorphism of organic nitrogen, or both processes likely contributed to the origin of Pluto's N$_2$

description: N$_2$ plays a profound role in supporting processes on the surface and in the atmosphere of Pluto, yet the origin of Pluto's N$_2$ remains a mystery. However, this may begin to change as the $^{14}$N/$^{15}$N ratio of N$_2$ was recently estimated based on a non-detection of HC15N in Pluto's atmosphere, while accounting for $^{14}$N/$^{15}$N fractionation between HCN and N$_2$. Here, I show that, if this latter step of translating isotope ratios is adequately understood, then the derived $^{14}$N/$^{15}$N ratio represents the first distinguishing constraint on the origin of N$_2$. One finding of the present study is that isotopic fractionation between atmospheric N$_2$ and N$_2$-rich ices on Pluto does not appear to be significant. I infer a lower limit of ~197 for the $^{14}$N/$^{15}$N ratio of the dominant reservoir of N$_2$ on Pluto; i.e., mostly contained in Sputnik Planitia. From this lower limit, an endmember ammonia source of Pluto's N$_2$ can be ruled out. I perform N isotope mixing calculations that enable quantitative understanding of the relationships between contributions by primordial N$_2$, NH$_3$, and nitrogen originally sourced in organic materials (Norg) to Pluto's observed N$_2$ inventory. These calculations address how uncertainties in the isotopic composition of Norg and the history of atmospheric escape affect the allowed ranges of primordial N$_2$, NH$_3$, and Norg contributions. While present uncertainties are substantial, I find that a contribution by primordial N$_2$, Norg, or both is implied, and the sum of their contributions should be at least ~45%. Hence, Pluto likely formed from building blocks that were cold enough to trap N$_2$, or Pluto has a thermally processed and dynamic interior that supports generation of N$_2$ from Norg and N$_2$ transport to the surface. The lower limit on $^{14}$N/$^{15}$N suggests that NH$_3$ has been a less significant contributor to the origin of N$_2$ on Pluto than on Titan.

description: We survey the coevolutionary dynamics of network topology and group interactions in opinion formation, grounded on a coevolving nonlinear voter model. The coevolving nonlinear voter model incorporates two mechanisms: group interactions implemented through nonlinearity in the voter model and network plasticity demonstrated as the rewiring of links to remove connections between nodes in different opinions. We show that the role of group interactions, implemented by the nonlinearity can significantly impact both the dynamical outcomes of nodes' state and the network topology. Additionally, we review several variants of the coevolving nonlinear voter model considering different rewiring mechanisms, noise of flipping nodes' state, and multilayer structures. We portray the various aspects of the coevolving nonlinear voter model as an example of network coevolution driven by group interactions, and finally, present the implications and potential directions for future research.

The theoretical calculations have been verified by molecular dynamics simulations and normal modes analysis.

Water Under the Bridge: A Novel (Exegesis: Remembering Torture: Survivor Narratives of the 1987-90 Insurgency in Sri Lanka)
Creators: name: Perera, Vihanga
Publisher: name: The Australian National University
Year: 2021

description: The research consists of a historically-informed work of fiction and a dissertation situated in the political emergency in Sri Lanka during 1987-90. The fiction is anchored in five intersectional narratives that represent the emergence of violence and its reception in two villages in the Kandy district of the Central Province. The narratives read as retrospective biographies and are built on the presences and absences in storied memories. The project is informed by Michael Rothberg's theory of 'multidirectional memory' and the emphasis Rothberg places on narrative modalities that go beyond conventional realist and anti-realist modes in narrating trauma: 'traumatic realism'. In its exegesis, the study focuses on the representation of torture camps in published survivor narratives during the emergency. Focused on the work of three survivors - Victor Gunathilake, Ajith Perakum Jayasinghe, and Rohitha Munasinghe - the discussion explores the survivor narrative as a counter-history that challenges privileged narratives of pro-establishment literature. While the study explores the processes through which victims of torture work-through their incarceration experiences to foster a critical balance and distance to narrate past trauma, it also understands the role of such narratives in post-conflict restoration.

description: This paper continues the studies of symbolic integration by focusing on the stability problems on D-finite functions. We introduce the notion of stability index in order to investigate the order growth of the differential operators satisfied by iterated integrals of D-finite functions and determine bounds and exact formula for stability indices of several special classes of differential operators. With the basic properties of stability index, we completely solve the stability problem on general hyperexponential functions.

description: We prove the existence and give constructions of a $(p(k)-1)$-fold perfect resolvable $(v, k, 1)$-Mendelsohn design for any integers $v > k \ge 2$ with $v \equiv 1 \mod k$ such that there exists a finite Frobenius group whose kernel $K$ has order $v$ and whose complement contains an element $ϕ$ of order $k$, where $p(k)$ is the least prime factor of $k$. Such a design admits $K \rtimes \langle ϕ\rangle$ as a group of automorphisms and is perfect when $k$ is a prime. As an application we prove that for any integer $v = p_{1}^{e_1} \ldots p_{t}^{e_t} \ge 3$ in prime factorization, and any prime $k$ dividing $p_{i}^{e_i} - 1$ for $1 \le i \le t$, there exists a resolvable perfect $(v, k, 1)$-Mendelsohn design that admits a Frobenius group as a group of automorphisms. We also prove that, if $k$ is even and divides $p_{i} - 1$ for $1 \le i \le t$, then there are at least $φ(k)^t$ resolvable $(v, k, 1)$-Mendelsohn designs that admit a Frobenius group as a group of automorphisms, where $φ$ is Euler's totient function.

description: In der Philosophie des Geistes ist umstritten, ob es nichtbegriffliche, z.B. sensorische Episoden gibt, die im vollen, nichtmetaphorischen Wortsinn als Repräsentationen, d.h. als kognitiv und irrtumsanfällig, gelten dürfen. Dabei wird der Begriff der Information mitunter für die Möglichkeit nichtbegrifflicher Repräsentation in Anspruch genommen. Hier soll ein Vorschlag zur Güte gemacht werden. Der amerikanische Philosoph Wilfrid Sellars (1912-1989) hält sensorische Episoden für nichtkognitiv, hat aber in einer Bildtheorie des Elementarsatzes unbemerkt und malgré lui den Grund für eine Sichtweise gelegt, die sensorische Episoden als begriffliche Information zu erkennen gibt. Diese Sichtweise lässt sich auf die lebensweltlichen Dinge ausdehnen, deren sensorische Qualitäten wir wahrnehmen. Dinge sind in einem erweiterten, aber nichtmetaphorischen Sinn als Sätze über sie selber lesbar. Mit dieser Lesbarkeitsthese wird die Natur in den Bereich der Gründe und Begriffe hereingeholt oder umgekehrt der Bereich der Gründe auf die Natur ausgedehnt.

description: We present ERNIE, a computer program which generates nuclear reactor electron antineutrinos and inverse beta decay events induced by these particles, using the Monte-Carlo method. The program allows the usage of different antineutrino energy spectra models and can simulate the time evolution of the overall antineutrino spectrum because of the burn-up effect. The output of the program can readily be used in detector simulations made with eg. GEANT 4.

description: The stable center conjecture asserts that the space of stable distributions in the Bernstein center of a reductive p-adic is closed under convolution. It is closely related to the notion of an L-packet and endoscopy theory. We describe a categorical approach to the depth zero part of the conjecture. As an illustration of our method, we show that the Bernstein projector to the depth zero spectrum is stable.

Making the new, normal: re-presenting mothers' subjectivities and their creative potential against persistent patriarchal models
Creators: name: Freney, Zoe
Publisher: name: The Australian National University
Year: 2022

description: This practice-based research project, given urgency by the impacts of COVID-19, seeks to account for the lived experiences of some contemporary mothers in western society, privileging representation as key in structuring ideologies of motherhood and mothers' behaviours. Through studio practices of drawing and painting, as well as digital photographic and textile processes, the project recuperates images of mothers in contemporary western visual culture, challenging their denigration and exploitation. Instead, motherhood and the domestic sphere are depicted as ethical and generative sites of innovation and potential. Taking a matricentric feminist stance and responding to Bracha Ettinger's theories of the matrixial and subjectivity in the feminine, the project employs artistic processes to articulate a mother's changing experience of identity and maternal subjectivity. Drawing on my own experiences of mothering, the 'new' that this project seeks to bring to the fore is the new maternal subject, a mother who is changed through mothering, for whom a new identity is born in relation to those of her dependent others, the spaces, situations, and paraphernalia of her work. The artworks produced recognise the real complexities of mothering and depict its catastrophes, ambiguities, doubts, and pleasures.
Magnetic-moment measurements by the transient-field and recoil-in-vacuum techniques in fpg-shell nuclei

description: Picosecond-lifetime nuclear-state g factors are challenging to measure, with the transient-field (TF) and recoil-in-vacuum (RIV) techniques best able to probe them. The TF is experienced by a swift ion traversing a polarised ferromagnetic material, while RIV relies on hyperfine interactions between the nucleus and its electrons that occur in isolated ions. Both techniques often require independent calibration, a key limitation in their use. The objective of this thesis is to improve the precision of g-factor measurements with these techniques. This was achieved by developing procedures that minimise systematic uncertainty in TF measurements to obtain reliable relative g factors, and then scaling them by developing atomic-structure calculations that enabled absolute g factors to be determined from RIV measurements focused on Na-like ions. Relative TF measurements were used to determine the first-excited-state g-factor ratio between Mg-24 and Mg-26, which was then scaled using a literature value of g(Mg-24), obtained using RIV, to determine g(Mg-26). TF measurements were also performed to obtain first-excited-state g-factor ratios between the stable even-A isotopes of Ge and Se, with the first-ever simultaneous measurement performed on isobaric nuclides (Ge-74, Se-74) in a cocktail beam. An ab initio approach to modelling Fe-56 first-excited-state time-differential RIV data focused on Na-like ions was developed. Time-differential Ge-76 and time-integral Fe-54,56 first-excited-state data were also analysed. The analysis utilised a Monte-Carlo simulation of atomic decays to model the hyperfine interaction through time. The combined use of relative TF and calibration-independent RIV measurements allowed the determination of precise absolute g-factor values. These were used to interrogate TF-strength calibrations, and shell-model predictions. Together, TF and RIV procedures presented in this work were effective in determining accurate g-factor values with improved precision in picosecond-lifetime nuclear states.

description: The evolution of vector solitons under nonlinearity management is studied. The averaged over strong and rapid modulations in time of the inter-species interactions vector Gross-Pitaevskii equation (GPE) is derived. The averaging gives the appearance of the effective nonlinear quantum pressure depending on the population of the other component. Using this system of equations, the existence and stability of the vector solitons under the action of the strong nonlinearity management (NM) is investigated. Using a variational approach the parameters of NM vector solitons are found. The numerical simulations of the full time-dependent coupled GPE confirms the theoretical predictions.

description: In this paper, I propose a theory that black holes and white holes have singularities, and black holes absorb everything that comes near them. I suggest that since these holes have singularities, which are the cause of big bangs, and they are connected through wormholes, there could be big bangs and creation of more universes inside the black hole. I also discuss the possibility of the existence of white holes, which are the opposite of black holes and instead of absorbing everything, they emit everything. Furthermore, as the black hole continues to absorb matter, the singularity at its core becomes increasingly dense and time itself becomes distorted, potentially leading to a breakdown of our conventional understanding of time and space. This could open up the possibility of time travel or other exotic phenomena that we have yet to fully comprehend,
