description: This paper deals with the solution of Maxwell's equations to model the electromagnetic fields in the case of a layered earth. The integrals involved in the solution are approximated by means of a novel approach based on the splitting of the reflection term. The inverse problem, consisting in the computation of the unknown underground conductivity distribution from a set of modeled magnetic field components, is also considered. Two optimization algorithms are applied, based on line- and global-search methods, and a new minimization approach is presented. Several EM surveys from the ground surface are simulated, considering the horizontal coplanar (HCP) and perpendicular (PRP) magnetic dipolar configurations. The numerical experiments, carried out for the study of river-levees integrity, allowed to estimate the errors associated to these kind of investigations, and confirm the reliability of the technique.

description: The monodromy relations in string theory provide a powerful and elegant formalism to understand some of the deepest properties of tree-level field theory amplitudes, like the color-kinematics duality. This duality has been instrumental in tremendous progress on the computations of loop amplitudes in quantum field theory, but a higher-loop generalisation of the monodromy construction was lacking. In this letter, we extend the monodromy relations to higher loops in open string theory. Our construction, based on a contour deformation argument inside open string diagrams, leads to new identities that relate planar and non-planar topologies in string theory. We write one and two-loop monodromy formulae explicitly at any multiplicity. In the field theory limit, at one-loop we obtain identities that reproduce known results. At two loops, we check our formulae by unitarity in the case of the four-point N=4 super-Yang-Mills amplitude.

description: Exploiting efficient and affordable treatment technology for fluoride removal via adsorption is highly desirable. In this study, calcinedhydrotalcites with different Mg/Al molar ratios were prepared. Layered double hydroxides calcined at 450 have been shown to recover their original layered structure in the presence of appropriate anions which may enhance its adsorption capacity. Uptake of fluoride ion from aqueous solution by CHT was investigated by batch experiments. The response surface methodology was applied to optimize the adsorption capacity by employing a factorial design. The optimal pH, initial fluoride concentration and Mg/Al molar ratio in CHT were found to be 6.0, 5mg/L and 2 respectively for the maximum percentage adsorption of 94.4%.The equilibrium isotherm showed that the uptake of fluoride ion by CHT was consistent with the Langmuir and Freundlich equations and that the Langmuir model gave a better fit to the experimental data than the Freundlich model. The maximum uptake capacity of CHT for fluoride ion by the Langmuir isotherm model was estimated to be 0.4762 mg/g. The influence of varying pH of solution, initial fluoride concentration and Mg/Al molar ratio in the structure of CHT on the kinetics of fluoride removal has also been explored. Kinetic models were used to fit the experimental data, and it was found that the pseudo-second-order kinetics model could be used to describe the uptake process satisfactorily. The present work demonstrates that calcinedhydrotalcites may be promising adsorbents for effective removal of fluorine from water resources.

description: Los polifenoles son compuestos formados por grandes múltiplos de unidades estructurales de fenol, ampliamente considerados como un grupo importante de antioxidantes altamente efectivos por su potente capacidad de eliminación de radicales libres y protecciones contra la oxidación, sin embargo, se han asociado varias limitaciones con el uso de estos compuestos fenólicos, debido a su baja biodisponibilidad, baja solubilidad en agua, catabolismo y excreción rápida y, baja estabilidad en condiciones ambientales, de procesamiento y gastrointestinales; además, son sensibles a las condiciones físicas y químicas, como la luz, el calor y la oxidación. Es por ello que la microencapsulación, toma importancia en los procesos que permiten incorporar materiales, generalmente activos, en una pared porosa que los protege y que puede resolver estos problemas. Como objetivo de la presente revisión, se tiene presentar una visión general sistemática de diferentes métodos de microencapsulación aplicados para cargar compuestos polifenólicos naturales, las técnicas y materiales más frecuentemente utilizados en la encapsulación, así como realizar comparaciones del tamaño, eficiencia de encapsulación (EE%), carga y comportamiento de la liberación del contenido polifenólico de las micropartículas, para que puedan servir como herramienta en futuros trabajos de investigación. Como resultados, se encontró que las principales técnicas de encapsulación para polifenoles son el secado por aspersión, la extrusión, la coacervación, la liofilización y la gelificación iónica, empleando como materiales de recubrimiento principalmente y en forma general los polímeros sintéticos y polímeros de biomateriales tales como carbohidratos, lípidos y proteínas de origen animal y vegetal. Entre los factores que afectan el tamaño de las micropartículas y la EE% están las diferentes técnicas de microencapsulación, el material de recubrimiento utilizado y la concentración de este, la temperatura, el pH, entre otros. Finalmente, para el estudio del comportamiento de liberación de las micropartículas se utilizan el procedimiento especificado por la USP (Farmacopea Norteamericana), agitación de viales, diálisis, celdas de Franz, entre otros, donde las micropartículas son incubadas en el medio y se determina su liberación con el tiempo.

description: While free/non-potential magnetic energy is a necessary element of any active phenomenon in the solar corona, its role as a marker of the trigger of eruptive process remains elusive. Based on the unique decomposition of the magnetic field into potential and non-potential components, magnetic energy and helicity can also both be uniquely decomposed into two quantities. Using two 3D MHD parametric simulations of a configuration that can produce coronal jets, we compare the dynamics of the magnetic energies and of the relative magnetic helicities. Both simulations share the same initial set-up and line-tied bottom-boundary driving profile. However, they differ by the duration of the forcing. In one simulation the system is driven sufficiently so that an helical jet is induced. The generation of the jet is however markedly delayed: a relatively long phase of lower-intensity reconnection takes place before the jet is eventually induced. In the other reference simulation, the system is driven during a shorter time, and no jet is produced. As expected, we observe that the Jet producing simulation contains a higher value of non-potential energy and non-potential helicity. Focusing on the phase between the end of the driving-phase and the jet generation, we note that magnetic energies remain relatively constant, while magnetic helicities have a noticeable evolution. During this post-driving phase, the ratio of the non-potential to total magnetic energy very slightly decreases while the helicity eruptivity index significantly increases. The jet is generated when the system is at the highest value of this helicity eruptivity index. This proxy critically decreases during the jet generation phase. The free energy also decreases but does not present any peak when the jet is being generated.

Fast Algorithms for Demixing Sparse Signals from Nonlinear Observations

Year: 2016

description: We study the problem of demixing a pair of sparse signals from noisy, nonlinear observations of their superposition. Mathematically, we consider a nonlinear signal observation model, $y_i = g(a_i^Tx) + e_i, \ i=1,\ldots,m$, where $x = Φw+Ψz$ denotes the superposition signal, $Φ$ and $Ψ$ are orthonormal bases in $\mathbb{R}^n$, and $w, z\in\mathbb{R}^n$ are sparse coefficient vectors of the constituent signals, and $e_i$ represents the noise. Moreover, $g$ represents a nonlinear link function, and $a_i\in\mathbb{R}^n$ is the $i$-th row of the measurement matrix, $A\in\mathbb{R}^{m\times n}$. Problems of this nature arise in several applications ranging from astronomy, computer vision, and machine learning. In this paper, we make some concrete algorithmic progress for the above demixing problem. Specifically, we consider two scenarios: (i) the case when the demixing procedure has no knowledge of the link function, and (ii) the case when the demixing algorithm has perfect knowledge of the link function. In both cases, we provide fast algorithms for recovery of the constituents $w$ and $z$ from the observations. Moreover, we support these algorithms with a rigorous theoretical analysis, and derive (nearly) tight upper bounds on the sample complexity of the proposed algorithms for achieving stable recovery of the component signals. We also provide a range of numerical simulations to illustrate the performance of the proposed algorithms on both real and synthetic signals and images.
Tracing contexts in events of young people’s party drug use

description: Consumption contexts have been shown to play a significant role in how young people use illicit party drugs such as MDMA, methamphetamines, cocaine, and psychedelics. Current research approaches tend to deploy macro-structural, social or cultural explanations for the role of context in drug use, which have difficulty accounting for the specific and diverse drug use practices evident in particular times and spaces. To address this, in this research I developed a novel research approach to trace how drug use unfolds during particular events or occasions at music festivals and licensed venues in Melbourne, Australia. Drawing conceptual and methodological sensitivities from Actor-Network Theory (ANT) within an ethnographic methodology, I explored how social, spatial, material and temporal aspects of consumption contexts mediated young people’s drug use events. Data were generated through in-depth interviews with young people aged 18-23 years; participant-written diaries and diary-interviews; and participant observation at music festivals and licensed venues. I used these data to generate an innovative way of empirically examining the role of contexts based on the notion of events and event analysis. In this thesis, I discuss the challenges and opportunities presented by doing ANT-inspired social research, and present my empirical findings in four publications reproduced in Chapters 4–7. In the first of these publications, I argue that examining drug use events provides a way forward for tracing the role of contexts in young people’s party drug use practices, presenting a case study of MDMA use by a young man. In the second publication, I demonstrate how the socio-spatial relations of campsites at multiple-day music festivals are involved in generating drug knowledge, norms, access, exchange, harm and harm reduction practices at festivals. Thirdly, in a book chapter co-authored with Jakob Demant, I investigate how police interventions using drug-detection (sniffer) dogs at music festival entrances impact young people’s drug use at festivals. In the final publication, co-author Cameron Duff and I explore how posthumanist approaches to social research, such as ANT, can contribute to alternative articulations of human subjectivity. We propose that framing subjectivity in terms of ‘tendencies’ and ‘trajectories’ should facilitate empirical and conceptual investigation of the role of the human subject in drug use events. Throughout the thesis I contend that it is necessary to explore the ways in which spaces are made to have particular effects by a collection of varied actors and forces. By way of conclusion, the final chapter considers the implications of my empirical and theoretical findings for the design of innovative research programs and practical interventions to prevent event-related harms arising from young people’s party drug use.

Perinatal and obstetric health outcomes of eastern African immigrant women in Victoria, Australia: a population-based study

description: Submission note: A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Public Health to the Judith Lumley Centre, School of Nursing and Midwifery, College of Science, Health and Engineering, La Trobe University, Bundoora.

Background: Births to immigrant women are increasing in many developed countries including Australia, where over a quarter of births are to foreign-born women. Previous obstetric and perinatal health outcome studies of immigrant populations have yielded mixed results. Therefore, understanding of immigrant women’s birth outcomes is far from complete. Australia has admitted many African immigrants of refugee background beginning in the 1990s, but evidence about African women’s birth outcomes in general and Eastern African immigrants in particular is lacking in Australia. This study described and investigated the independent association of adverse perinatal outcomes [low birthweight, preterm birth, small for gestational age births, 5’Apgar score, perinatal mortality] and obstetric health outcomes [caesarean section (CS), trial of labour and successful vaginal birth after caesarean section (VBAC), episiotomy use and severe perineal tear] for Eastern African maternal countries of birth in comparison with Australian born women. Methods: A population-based study of singleton births to women born in one of the Eastern African (Eritrea, Ethiopia, Somalia and Sudan) countries or Australia was conducted using the routine state-wide validated Victorian Perinatal Data Collection (VPDC) in Australia. Results: Compared with mothers born in Australia, Eastern African immigrants had elevated odds of perinatal mortality and a number of other adverse perinatal health outcomes. Moreover, primary CS, failed attempted VBAC, severe perineal tear and episiotomy use were more common among Eastern African immigrants. The observed associations remained strong even after adjusting for available clinical and socio-demographic confounding factors. Nonetheless, individual country of birth analysis also indicated differentiated results. Conclusions: Overall, Eastern African maternal countries of birth were associated with increased adverse perinatal health outcomes and increased obstetric interventions. However, adverse outcomes were not readily explained by maternal characteristics or clinical risk factors. The findings suggest the need for enhanced surveillance and improved health care delivery for these immigrants. Further research around other potential explanatory factors (communication issues, support available for pregnant immigrant women, care differentials) is also needed.

description: All-cause mortality is a very coarse grain, albeit very reliable, index to check the health implications of lifestyle determinants, systemic threats and socio-demographic factors. In this work we adopt a statistical-mechanics approach to the analysis of temporal fluctuations of all-cause mortality, focusing on the correlation structure of this index across different regions of Italy. The correlation network among the 20 Italian regions was reconstructed using temperature oscillations and travellers' flux (as a function of distance and region's attractiveness, based on GDP), allowing for a separation between infective and non-infective death causes. The proposed approach allows monitoring of emerging systemic threats in terms of anomalies of correlation network structure.

description: In the light of regularized dynamic time warping kernels, this paper re-considers the concept of time elastic centroid for a setof time series. We derive a new algorithm based on a probabilistic interpretation of kernel alignment matrices. This algorithm expressesthe averaging process in terms of a stochastic alignment automata. It uses an iterative agglomerative heuristic method for averagingthe aligned samples, while also averaging the times of occurrence of the aligned samples. By comparing classification accuracies for45 heterogeneous time series datasets obtained by first nearest centroid/medoid classifiers we show that: i) centroid-basedapproaches significantly outperform medoid-based approaches, ii) for the considered datasets, our algorithm that combines averagingin the sample space and along the time axes, emerges as the most significantly robust model for time-elastic averaging with apromising noise reduction capability. We also demonstrate its benefit in an isolated gesture recognition experiment and its ability tosignificantly reduce the size of training instance sets. Finally we highlight its denoising capability using demonstrative synthetic data:we show that it is possible to retrieve, from few noisy instances, a signal whose components are scattered in a wide spectral band.

description: The Sun is the source of different types of radio bursts that are associated with solar flares, for example. Among the most frequently observed phenomena are type III solar bursts. Their radio images at low frequencies (below 100 MHz) are relatively poorly studied due to the limitations of legacy radio telescopes. We study the general characteristics of types IIIb and U with stria structure solar radio bursts in the frequency range of 20 - 80 MHz, in particular the source size and evolution in different altitudes, as well as the velocity and energy of electron beams responsible for their generation. In this work types IIIb and U with stria structure radio bursts are analyzed using data from the LOFAR telescope including dynamic spectra and imaging observations, as well as data taken in the X-ray range (GOES and RHESSI satellites) and in the extreme ultraviolet (SDO satellite). In this study we determined the source size limited by the actual shape of the contour at particular frequencies of type IIIb and U solar bursts in a relatively wide frequency band from 20 to 80 MHz. Two of the bursts seem to appear at roughly the same place in the studied active region and their source sizes are similar. It is different in the case of another burst, which seems to be related to another part of the magnetic field structure in this active region. The velocities of the electron beams responsible for the generation of the three bursts studied here were also found to be different.

description: Accurate modeling of the Sun's coronal magnetic field and solar wind structures require inputs of the solar global magnetic field, including both the near and far sides, but the Sun's far-side magnetic field cannot be directly observed. However, the Sun's far-side active regions are routinely monitored by helioseismic imaging methods, which only require continuous near-side observations. It is therefore both feasible and useful to estimate the far-side magnetic-flux maps using the far-side helioseismic images despite their relatively low spatial resolution and large uncertainties. In this work, we train two machine-learning models to achieve this goal. The first machine-learning training pairs simultaneous SDO/HMI-observed magnetic-flux maps and SDO/AIA-observed EUV 304$Å$ images, and the resulting model can convert 304$Å$ images into magnetic-flux maps. This model is then applied on the STEREO/EUVI-observed far-side 304$Å$ images, available for about 4.3 years, for the far-side magnetic-flux maps. These EUV-converted magnetic-flux maps are then paired with simultaneous far-side helioseismic images for a second machine-learning training, and the resulting model can convert far-side helioseismic images into magnetic-flux maps. These helioseismically derived far-side magnetic-flux maps, despite their limitations in spatial resolution and accuracy, can be routinely available on a daily basis, providing useful magnetic information on the Sun's far side using only the near-side observations.

description: Pendulums have long been used as force sensors due to their ultimately low dissipation (high-quality factor) characteristic. They are widely used in the measurement of the gravitational constant, detection of gravitational waves, and determination of ultralight dark matter. Furthermore, it is expected that the quantum nature of gravity will be demonstrated by performing quantum control for macroscopic pendulums. Recently, we have demonstrated that quantum entanglement between two pendulums can be generated using an optical spring [D. Miki, N. Matsumoto, A. Matsumura, T. Shichijo, Y. Sugiyama, K. Yamamoto, and N. Yamamoto, arXiv:2210.13169 (2022)]; however, we have ignored that an optical spring can reduce the quality factor (Q-factor) by applying normal-mode splitting between the pendulum and rotational modes possessing relatively high dissipation. Herein, we analyze a system composed of a cylinder suspended using a beam (a suspended mirror, i.e., a pendulum) and an optical spring to consider normal-mode splitting. The reduction in Q-factor is determined only by the beam parameters: the ratio of the radius of the mirror to the length of the beam, and the ratio of the frequency of the rotational mode to the pendulum mode in the absence of cavity photons. In our analysis, we find that the reduction factor $4.38$ is reproduced, which is consistent with the experimental result in Matsumoto \textit{et al.} [N. Matsumoto, S. B. Catan$\tilde{\text{o}}$-Lopez, M. Sugawara, S. Suzuki, N. Abe, K. Komori, Y. Michimura, Y. Aso, and K. Edamatsu, Phys. Rev. Lett. 122, 071101 (2019)]. Our analysis shows that low dissipation (high quality) can be reached using an optical spring for the realistic pendulum system considering the rotational degree of freedom.

This thesis historicises the medicalisation of sexual appetite in Europe and in the United States across the nineteenth to twenty-first centuries. The interrelationship of quantity and quality, lack and excess are yet to be explored within intellectual histories of sexuality. Historiographies of sexuality in both the sciences and the humanities have been dominated by accounts of the emergence of object choice, desire and orientation. Through a genealogical approach that draws on the writings of Michel Foucault and Georges Canguilhem, amongst others, I explore key “moments” in the pathologisation of sexuality and show how techniques of viewing, reading, writing, indexing and diagnosing the body were central to the medicalisation of sexual appetite. In each chapter, I analyse different techniques that were inherent in the diagnosis and management of sexual balance, which in turn have constituted and mediated norms of sexual subjectivity. The aim of the thesis is to examine how the question of amounts, that is how much one desires, was never far removed from studies of sexual orientation across the nineteenth to twenty-first centuries. Three key questions are central to this thesis: how has knowledge on sexual appetite developed? What techniques emerge from the problematisation of sexual appetite? And finally, how are subjectivities configured through the problematisation of sexual appetite and techniques of management? The thesis argues that the fluctuations of sexual appetite, lack and excess, quality and quantity, have always underpinned histories of sexual object choice. It also contends that the medical techniques that inform, produce and transform discourses and knowledges on the sexual appetites lead to the formation of subjectivities for the self-management of sexual balance.

description: Gluconic acid is a multifunctional organic acid which has increasing interest in different application because of its non-corrosiveness, non-toxicity, readily biodegradability and environmentally friendly properties. This study involves gluconic acid production and investigation of different parameters on the yield of gluconic acid. Gluconic acid was produced from treated molasses by using Aspergillus carneus strain under submerged fermentation. To reduce the inhibition of heavy metals and inorganic salts in crude molasses, it requires being pretreated. Gluconic acid production was achieved by three subsequent steps such as pretreatment, fermentation and separation with characterization. To investigate the effect of variables, four factors with three levels Box -Bhenken Design expert 7.0.0 trial was used. Chemical characterization of gluconic acid was examined by Fourier transform infrared spectroscopy analysis. Results of Box -Behnken Design indicates that the optimum parameter were temperature 30 , Carbon source concentration 250.00g/L, pH 7 and incubation time 6.86 days to produce maximum yield of gluconic acid 61.96%. Fourier transform infrared spectroscopy analysis identifies and confirms the presence of gluconic acid in the product. Results showed that use of treated molasses for production of maximum yield of gluconic acid through submerged fermentation by using Aspergillus carneus were valuable, feasible and waste minimal.

description: Stealthy Coronal Mass Ejections (CMEs), lacking low coronal signatures, may result in significant geomagnetic storms. However, the mechanism of stealthy CMEs is still highly debated. In this work, we investigate whether there are differences between the stealthy and standard CMEs in terms of their dynamic behaviors. Seven stealthy and eight standard CMEs with slow speeds are selected. We calculate two-dimensional speed distributions of CMEs based on the cross-correlation method, rather than the unidimensional speed, and further obtain more accurate distributions and evolution of CME mechanical energies. Then we derive the CME driving powers and correlate them with CME parameters (total mass, average speed, and acceleration) for standard and stealthy CMEs. Besides, we study the forces that drive CMEs, namely, the Lorentz force, gravitational force, and drag force due to the ambient solar wind near the Sun. The results reveal that both the standard and stealthy CMEs are propelled by the combined action of those forces in the inner corona. The drag force and gravitational force are comparable with the Lorentz force. However, the impact of the drag and Lorentz forces on the global evolution of the stealthy CMEs is significantly weaker than that of the standard CMEs.

description: We report the discovery of a multiply-imaged gravitationally lensed Type Ia supernova, iPTF16geu (SN 2016geu), at redshift $z=0.409$. This phenomenon could be identified because the light from the stellar explosion was magnified more than fifty times by the curvature of space around matter in an intervening galaxy. We used high spatial resolution observations to resolve four images of the lensed supernova, approximately 0.3" from the center of the foreground galaxy. The observations probe a physical scale of $\sim$1 kiloparsec, smaller than what is typical in other studies of extragalactic gravitational lensing. The large magnification and symmetric image configuration implies close alignment between the line-of-sight to the supernova and the lens. The relative magnifications of the four images provide evidence for sub-structures in the lensing galaxy.

Density jump for oblique collisionless shocks in pair plasmas: allowed solutions

description: Shockwaves in plasma are usually dealt with using Magnetohydrodynamics (MHD). Yet, MHD entails the assumption of a short mean free path, which is not fulfilled in a collisionless plasma. Recently, for pair plasmas, we devised a model allowing to account for kinetic effects within an MHD-like formalism. Its relies on an estimate of the anisotropy generated when crossing the front, with a subsequent assessment of the stability of this anisotropy in the downstream. We solved our model for parallel, perpendicular and switch-on shocks. Here we bridge between all these cases by treating the problem of an arbitrarily, but coplanar, oriented magnetic field. Even though the formalism presented is valid for anisotropic upstream temperatures, only the case of a cold upstream is solved. We find extra solutions which are not part of the MHD catalog, and a density jump that is notably less in the quasi parallel, highly magnetized, regime. Given the complexity of the calculations, this work is mainly devoted to the presentation of the mathematical aspect of our model. A forthcoming article will be devoted to the physics of the shocks here defined.

Spin-chain model for strongly interacting one-dimensional Bose-Fermi mixtures

description: Strongly interacting one-dimensional (1D) Bose-Fermi mixtures form a tunable XXZ spin chain. Within the spin-chain model developed here, all properties of these systems can be calculated from states representing the ordering of the bosons and fermions within the atom chain and from the ground-state wave function of spinless noninteracting fermions. We validate the model by means of an exact diagonalization of the full few-body Hamiltonian in the strongly interacting regime. Using the model, we explore the phase diagram of the atom chain as a function of the boson-boson (BB) and boson-fermion (BF) interaction strengths and calculate the densities, momentum distributions, and trap-level occupancies for up to 17 particles. In particular, we find antiferromagnetic (AFM) and ferromagnetic (FM) order and a demixing of the bosons and fermions in certain interaction regimes. We find, however, no demixing for equally strong BB and BF interactions in agreement with earlier calculations that combined the Bethe ansatz with a local-density approximation.
