description: We consider the nonrelativistic model of coupling bare discrete states with continuum states in which the continuum states can have interactions among themselves. By partial-wave decomposition and constraint to the conserved angular momentum eigenstates, the model can be reduced to Friedrichs-like model with additional interactions between the continua. If a kind of factorizable form factor is chosen, the model can be exactly solvable, that is, the generalized discrete eigenstates including bound states, virtual states, and resonances, can all be represented using the original bare states, and so do the in-state and out-state. The exact $S$ matrix is thus obtained. We then discuss the behaviors of the dynamically generated $S$-wave and $P$-wave discrete states as the coupling is varying when there is only one self-interacting bare continuum state. We find that even when the potential is repulsive there could also be resonances and virtual states. In the $P$-wave cases with attractive interaction, we find that when there is a near-threshold bound state, there will always be an accompanying virtual state and we also give a more general argument of this effect.

Singing is a very popular activity, particularly in the United States, where it is reported that more people are involved in singing than any other recreational pursuit (Bell, 2004). In Australia, statistics show that singing is a very popular arts activity in the state of Victoria, with 16.9% of people taking part. This is ahead of the other activities surveyed which were music, performance, writing, painting and drawing, and is only exceeded in popularity by crafts. Rural and regional areas of central Victoria (Bendigo and Ballarat regions) reported one of the highest participation rates for singing in the state; between 20.51 and 24.16% exceeding most metropolitan areas (Wiseman and Brasher, 2007). In Victoria, there are 750 choirs registered with Community Music Victoria (CMV), but Executive Officer, Jon Hawkes believes there are many more active groups than are registered (personal communication 16 June, 2008).

description: Effective and safe therapies to counteract persistent inflammation are necessary. We developed erythrocyte-derived liposomes (EDLs) with intrinsic anti-inflammatory activity. The EDLs were prepared using lipids extracted from erythrocyte membranes, which are rich in omega-3 fatty acids with several health benefits. Diclofenac, a widely used anti-inflammatory drug, was incorporated into EDLs in relevant therapeutic concentrations. The EDLs were also functionalised with folic acid to allow their active targeting of M1 macrophages, which are key players in inflammatory processes. In the presence of lipopolysaccharide (LPS)-stimulated macrophages, empty EDLs and EDLs incorporating diclofenac were able to reduce the levels of important pro-inflammatory cytokines, namely interleukin-6 (IL-6; ≈85% and 77%, respectively) and tumour necrosis factor-alpha (TNF-α; ≈64% and 72%, respectively). Strikingly, cytocompatible concentrations of EDLs presented similar effects to dexamethasone, a potent anti-inflammatory drug, in reducing IL-6 and TNF-α concentrations, demonstrating the EDLs potential to be used as bioactive carriers in the treatment of inflammatory diseases.

description: In this paper we consider the dynamics of a massive spinor field in the background of the acoustic black hole spacetime. Although this effective metric is acoustic and describes the propagation of sound waves, it can be considered as a toy model for the gravitational black hole. In this manner, we study the properties of the dynamics of the fermion field in this "gravitational" rotating black hole as well as the vortex background. We compute the differential cross section through the use of the partial wave approach and show that an effect similar to the gravitational Aharonov-Bohm effect occurs for the massive fermion field moving in this effective metric. We discuss the limiting cases and compare the results with the massless scalar field case.

description: The electric conductivity of ionic solutions is well understood at low ionic concentrations of up to a few millimolar but becomes difficult to unravel at higher concentrations that are still common in nature and technological applications. A model for the conductivity at high concentrations was recently put forth for monovalent electrolytes at low electric fields. The model relies on applying a stochastic density-functional theory and using a modified electrostatic pair-potential that suppresses unphysical, short-range electrostatic interactions. Here, we extend the theory to multivalent ions as well as to high electric fields where a deviation from Ohm's law known as the Wien effect occurs. Our results are in good agreement with experiments and recent simulations.

Distributed Event Localization via Alternating Direction Method of Multipliers

description: This paper addresses the problem of distributed event localization using noisy range measurements with respect to sensors with known positions. Event localization is fundamental in many wireless sensor network applications such as homeland security, law enforcement, and environmental studies. However, most existing distributed algorithms require the target event to be within the convex hull of the deployed sensors. Based on the alternating direction method of multipliers (ADMM), we propose two scalable distributed algorithms named GS-ADMM and J-ADMM which do not require the target event to be within the convex hull of the deployed sensors. More specifically, the two algorithms can be implemented in a scenario in which the entire sensor network is divided into several clusters with cluster heads collecting measurements within each cluster and exchanging intermediate computation information to achieve localization consistency (consensus) across all clusters. This scenario is important in many applications such as homeland security and law enforcement. Simulation results confirm effectiveness of the proposed algorithms.

description: Schon eine naive und nur oberflächliche Betrachtung von mathematischen Texten belegt, dass in der Mathematik Symbole, Zeichen und Diagramme verschiedenster Form und Art vorkommen und auch eine wichtige Rolle spielen. Es ist daher naheliegend zu prüfen, ob die Wissenschaft von den Zeichen und deren Gebrauch, also die Semiotik, einen Beitrag zur Analyse, zum Verständnis, zur Interpretation und zur Rekonstruktion mathematischer Tätigkeiten liefern kann. Dies wurde in der Didaktik der Mathematik bereits vielfältig angedacht. Dabei wird neben dem Bezug auf die Semiotik von Saussure (Konzept von signifier/signified) in letzter Zeit vermehrt und intensiver die Semiotik von Charles S. Peirce herangezogen, vergleiche Hoffmann (2003a,b) oder Hoffmann und Plöger (2000). Von Peirce selbst stammt der Hinweis auf die zentrale Bedeutung von "Diagrammen" und diagrammatischem Denken in der Mathematik, was zum Beispiel in Dörfler (2004a,b,c) den Ausgangspunkt für weitere Analysen bildet. Nun bildet aber für die Peirce`sche Semiotik deren triadische Struktur die zentrale Charakteristik, und es muss gefragt werden, welche Schlüsse daraus für die Mathematik gezogen werden könnten. Ein erster, noch unbefriedigender Versuch in dieser Hinsicht wurde in Dörfler (2004d) unternommen. Hier wird nun eine eher radikale und wahrscheinlich unkonventionelle Anwendung der Peirce`schen Triade auf mathematische Zeichen vorgenommen.
When change is the only constant: the role of art making in mental health recovery

Art-based practices have attracted interest as a potentially therapeutic resource because they are in line with the whole person framework currently being adopted by Australian mental health services, as well as have high acceptability with consumers. Nevertheless, incorporation of art-based approaches into mental health services has been limited by claims of an insufficient evidence-base. This thesis involved gaining a deeper understanding of the roles of art making in mental health recovery among consumers of two psychosocial rehabilitation services in Victoria, Australia. Specifically, this study explored changes over one year in the lives of twelve participants who attended a variety of art-based programs. To gain a multifaceted perspective of this area of inquiry a mixed-methods approach was used incorporating pragmatism, empathetic phenomenology and co-operative inquiry as well as case study and art-based approaches. Importantly, establishing rapport and developing trust with the participants became integral to the values of the study. Collaboration with the participants where possible became a key to ensuring I was authentically reflecting their experiences and aligning myself with the recovery values. By intersubjectively responding to the experiences captured in the study I was also able to create knowledge more closely attuned with the participants. An analysis of the findings resulted in the identification of a number of key areas including that art making enabled the re-establishment of a psychosocial sense of self, provided a vessel by which personal meanings could be made, acted as a coping mechanism, encouraged interdependency, and assisted the development of multiple forms of identification beyond having a mental illness. Future strategies within mental health services could further integrate these aspects of art making into their practices, which would help to enhance the discovery of meaning, purpose and hope during the recovery process.

The current study investigated self-awareness, autonoetic memory and narrative skills of children with high-functioning autism (HFA) in comparison with typical developing (TD) children to further understand differences, if any, in developing personal perspectives for the interpretation and reconstruction of significant experiences. The participants, 20 children with HFA and 21 TD children were administered the Self-Description Questionnaire, the Children’s Memory Scale Family Picture subtest, and the Expression, Reception, and Recall of Narrative Instrument. In addition, the participants were asked to describe themselves, to recount a negative and positive significant event, to recall the details of a card game in an episodic memory task, as well as complete two autobiographical memory tasks. No group differences were found on reported self-perception, but the children with HFA gave fewer self-descriptions compared to the TD group. They also had more difficulty in the memory tasks, recalling less of, and required more time and prompting to recall specific events. Although no differences were found in literal comprehension and the use of evaluative devices, the children with HFA performed more poorly in generating, recalling and organizing core story ideas around a narrative framework and in the comprehension of inferential questions. This group also had more difficulty in using a subjective perspective for recounting personal experiences. An examination of the inter-relationships between self-awareness, episodic and autobiographical memory and narrative skills indicated that the children with HFA showed different patterns amongst these measures including a self-concept that reflected personal interests rather than personal traits, more reliance on semantic rather than personal episodic memory, and an increased tendency to recall memory details in preference to episodes. The lack of predictors for the domains in this group suggested decreased ability to apply these skills in an integrated framework for understanding and interpreting social situations.

Warm inflation with an oscillatory inflaton in the non-minimal kinetic coupling model

description: In the cold inflation scenario, the slow roll inflation and reheating via coherent rapid oscillation, are usually considered as two distinct eras. When the slow roll ends, a rapid oscillation phase begins and the inflaton decays to relativistic particles reheating the Universe. In another model dubbed warm inflation, the rapid oscillation phase is suppressed, and we are left with only a slow roll period during which the reheating occurs. Instead, in this paper, we propose a new picture for inflation in which the slow roll era is suppressed and only the rapid oscillation phase exists. Radiation generation during this era is taken into account, so we have warm inflation with an oscillatory inflaton. To provide enough e-folds, we employ the non-minimal derivative coupling model. We study the cosmological perturbations and compute the temperature at the end of warm oscillatory inflation.

description: The recent discovery of quantum many-body scar states has revealed the possibility of having states with low entanglement that violate the eigenstate thermalization hypothesis in nonintegrable systems. Such states with low entanglement entropy are rare but naturally exist in the integrable system of free fermions. Here, we demonstrate analytically that these atypical states would be always eliminated when an arbitrary weak interaction is introduced between the fermions. In particular, we show that the probability of having a many-body scar state with entanglement entropy satisfying a sub-volume scaling law decreases double exponentially as the system size. Thus, our results provide a quantitative argument for the disappearance of scar states in interacting fermion systems.

Fast Low-rank Shared Dictionary Learning for Image Classification

description: Despite the fact that different objects possess distinct class-specific features, they also usually share common patterns. This observation has been exploited partially in a recently proposed dictionary learning framework by separating the particularity and the commonality (COPAR). Inspired by this, we propose a novel method to explicitly and simultaneously learn a set of common patterns as well as class-specific features for classification with more intuitive constraints. Our dictionary learning framework is hence characterized by both a shared dictionary and particular (class-specific) dictionaries. For the shared dictionary, we enforce a low-rank constraint, i.e. claim that its spanning subspace should have low dimension and the coefficients corresponding to this dictionary should be similar. For the particular dictionaries, we impose on them the well-known constraints stated in the Fisher discrimination dictionary learning (FDDL). Further, we develop new fast and accurate algorithms to solve the subproblems in the learning step, accelerating its convergence. The said algorithms could also be applied to FDDL and its extensions. The efficiencies of these algorithms are theoretically and experimentally verified by comparing their complexities and running time with those of other well-known dictionary learning methods. Experimental results on widely used image datasets establish the advantages of our method over state-of-the-art dictionary learning methods.

Ultrasonography and image-guided corticosteroid injection for plantar fasciitis
Creators: name: McMillan, Andrew M.
Publisher: name: La Trobe
Year: 2023

description: Submission note: A thesis submitted in total fulfilment of the requirements for the degree of Doctor of Philosophy to the Department of Podiatry, School of Allied Health, Faculty of Health Sciences, La Trobe University, Bundoora.

Background: Plantar fasciitis is a common musculoskeletal condition that causes persistent pain under the heel. The disorder can affect a range of people from various age groups, and typically occurs without involvement of underlying systemic disease. The symptoms of plantar fasciitis can vary from a mild transitory irritation to a constant disabling pain, and people with the condition often experience a negative impact on their health-related quality of life. By reviewing the current literature and undertaking original investigations, this thesis will explore the diagnostic features of plantar fasciitis with an emphasis on ultrasonography, and determine the value of image-guided corticosteroid injection for treatment of the condition. Methodology: Three main projects were conducted for this thesis. Firstly, a systematic review was undertaken to establish the underlying tissue changes associated with heel pain, by drawing together evidence from a variety of diagnostic imaging studies. Secondly, a randomised controlled trial was carried out to investigate the effectiveness of corticosteroid injection for treatment of plantar fasciitis. This study incorporated an image-guided injection technique for delivery of the drug into the affected tissue. The third study further utilised ultrasonography to observe the imaging features of plantar fasciitis, with emphasis on vascular in-growth into the plantar fascia and the possible pain mechanisms involved with the condition. Findings: The findings of this thesis demonstrate that swelling and degeneration of the plantar fascia are common imaging features associated with heel pain. Ultrasound-guided injection with a highly soluble corticosteroid was shown to significantly reduce pain in the short-term, and the injection also reduced swelling of the plantar fascia over a three month period. These findings are important for clinical practice as they indicate that an image-guided corticosteroid injection is a safe and effective treatment for plantar fasciitis, and that such an injection leads to sustained physiological changes within the affected tissue. The final study presented in this thesis demonstrated that mild hyperaemia is associated with plantar fasciitis, but that markedly increased vascularity is not a feature of the condition.

Weak charges quantization in $SU(3)_{c} \otimes SU(n)_{L} \otimes U(1)_{Y}$ gauge models

description: After proving, in a previous paper, that the electric charge quantization occurs as a natural consequence in renormalizable $SU(3)_c \otimes SU(n)_{L} \otimes U(1)_{Y}$ gauge models, we take here a step further within the same paradigm in order to obtain the precise weak charges quantization. To this end a viable boson mass spectrum yields first, once a proper parametrization in the Higgs sector is employed. Hence, by diagonalizing the neutral bosons mass matrix, the quantized neutral weak charge operators are obtained. The Standard Model phenomenology is entirely recovered, as its scale ($v_{SM}=246$ GeV) is decoupled from the higher scale ($V\sim$ 10 TeV) specific to our generalized electro-weak unification.

description: We consider a broad family of higher-derivative extensions of four-dimensional Einstein gravity and study the multipole moments of rotating black holes therein. We carefully show that the various definitions of multipoles carry over from general relativity, and compute these multipoles for higher-derivative Kerr using the ACMC expansion formalism. We obtain the mass $M_{n}$ and current $S_{n}$ multipoles as a series expansions in the dimensionless spin; in some cases we are able to resum these series into closed-form expressions. Moreover, we observe the existence of intriguing relations between the corrections to the parity-odd multipoles $S_{2n}\neq 0$ and $M_{2n+1}\neq 0$ that break equatorial symmetry, and the parity-preserving corrections that only modify $S_{2n+1}$ and $M_{2n}$. Further, we comment on the higher-derivative corrections to multipole ratios for Kerr, and we discuss the phenomenological implications of the corrections to the multipole moments for current and future gravitational wave experiments.

The stock market reaction to dividend reductions and omissions: evidence from China

Publisher: name: La Trobe
Year: 2023

description: Submission note: A thesis submitted in total fulfilment of the requirements for the degree of Master of Economics to the School of Business, Faculty of Business, Economics and Law, La Trobe University, Bundoora.

This paper investigates the Chinese stock market reaction to the announcements of dividend reductions and omission. Previous domestic Chinese researches document that the Chinese stock market shows little reaction to cash dividend announcement, whereas the stock market reaction to dividend reductions and omission draws little attention in China. We have identified some problems in the previous Chinese studies. Firstly, the sample periods of these studies are typically too short, which make the results unreliable. Secondly, most of the studies use a short time period to calculate the abnormal returns that may be driven by the investors trading before the dividend date. Finally, most of these researches do not take into consideration the effect of other important information released with the dividend announcements at the same time. To address these issues, we firstly use the data over a period of 20 years starting from 1990-the year that the Chinese stock market starts trading to 2009. Secondly, we employ a similar methodology by Liu, Szewczyk, and Zantout (2008) and perform a rolling portfolio approach and use the Fama-French 3-factor model to calculate the post-announcement long-term abnormal returns. Thirdly, we use the matching method and the subsample tests to examine the robustness of the dividend announcement drift. After controlling for firm size, the unexpected earnings and government ownership, we find no evidence of the dividend announcement drift in China. We also show the important factors that affect the long-term abnormal return through the cross-sectional test.

Fixed support positive-definite modification of covariance matrix estimators via linear shrinkage

description: In this work, we study the positive definiteness (PDness) problem in covariance matrix estimation. For high dimensional data, many regularized estimators are proposed under structural assumptions on the true covariance matrix including sparsity. They are shown to be asymptotically consistent and rate-optimal in estimating the true covariance matrix and its structure. However, many of them do not take into account the PDness of the estimator and produce a non-PD estimate. To achieve the PDness, researchers consider additional regularizations (or constraints) on eigenvalues, which make both the asymptotic analysis and computation much harder. In this paper, we propose a simple modification of the regularized covariance matrix estimator to make it PD while preserving the support. We revisit the idea of linear shrinkage and propose to take a convex combination between the first-stage estimator (the regularized covariance matrix without PDness) and a given form of diagonal matrix. The proposed modification, which we denote as FSPD (Fixed Support and Positive Definiteness) estimator, is shown to preserve the asymptotic properties of the first-stage estimator, if the shrinkage parameters are carefully selected. It has a closed form expression and its computation is optimization-free, unlike existing PD sparse estimators. In addition, the FSPD is generic in the sense that it can be applied to any non-PD matrix including the precision matrix. The FSPD estimator is numerically compared with other sparse PD estimators to understand its finite sample properties as well as its computational gain. It is also applied to two multivariate procedures relying on the covariance matrix estimator -- the linear minimax classification problem and the Markowitz portfolio optimization problem -- and is shown to substantially improve the performance of both procedures.

Stiffening or softening of elastic media: Anomalous elasticity near phase transitions

description: We present the general theory of Ising transitions in isotropic elastic media with vanishing thermal expansion. By constructing a minimal model with appropriate spin-lattice couplings, we show that in two dimensions near a continuous transition the elasticity is anomalous in unusual ways: the system either significantly stiffens with a hitherto unknown unique positional order logarithmically stronger than quasi-long range order, or, as the inversion-asymmetry of the order parameter in its coupling with strain increases, it destabilizes when system size $L$ exceeds a finite threshold. At three dimensions, stronger inversion-asymmetric couplings induce instability to the long-range positional order for all $L$. Sufficiently strong order parameter-displacement couplings can also turn the phase transition first order at all dimensions, concomitant with finite jumps in the elastic modulii across the transition. Our theory establishes a {\em one-to-one correspondence} between the order of the phase transitions and anomalous elasticity near the transitions.

description: The first deep-field observations of the JWST have immediately yielded a surprisingly large number of very high redshift candidates, pushing the frontier of observability well beyond $z\gtrsim10$. We here present a detailed SED-fitting analysis of the 15 gravitationally lensed $z\sim10-16$ galaxy candidates detected behind the galaxy cluster SMACS J0723.3-7327 in Atek et al. (2022) using the BEAGLE tool. Our analysis makes use of dynamical considerations to place limits on the ages of these galaxies and of all three published SL models of the cluster to account for lensing systematics. We find these galaxies to have relatively low stellar masses $M_{\star}\sim10^7-10^8\,\mathrm{M}_{\odot}$ and young ages $t_{\mathrm{age}}\sim10-100$\,Myr. Due to their very blue UV-slopes, down to $β\sim-3$, all of the galaxies in our sample have extremely low dust attenuations $A_V\lesssim0.02$. Placing the measured parameters into relation, we find a very shallow $M_{\star}-M_{\mathrm{UV}}$-slope and high sSFRs above the main sequence of star-formation with no significant redshift-evolution in either relation. This is in agreement with the bright UV luminosities measured for these objects and indicates that we are naturally selecting galaxies that are currently undergoing a star-bursting episode at the time they are observed. Finally, we discuss the robustness of our high-redshift galaxy sample regarding low-redshift interlopers and conclude that low-redshift solutions can safely be ruled out for roughly half of the sample, including the highest-redshift galaxies at $z\sim12-16$. These objects represent compelling targets for spectroscopic follow-up observations with JWST and ALMA.

description: Highly filled conductive polymer composites (CPCs) are widely used in applications such as bipolar plate materials for polymer electrolyte membrane fuel cells and redox flow batteries, electromagnetic interference shielding and sensors due to their useful electrical properties. A common method for determining through-plane electrical conductivities $\left(σ_{\rm tp} \right)$ of such highly filled CPCs applies a conductive carbon paper between electrodes and sample with application of external pressure to improve electrical contact. We show the pressure-dependence of the measured $σ_{\rm tp}$ can be eliminated by using a liquid metal such as the gallium-indium eutectic alloy (EGaIn) as contact material. Results indicate that EGaIn reduces contact resistances and cause three to five times larger $σ_{\rm tp}$ compared to measurements with carbon paper contacts and pressures up to 20 bar.

description: A novel method for generating GigaGauss solenoidal field in laser-plasma bubble, using screw-shaped laser pulses, has been recently presented in arXiv:1604.01259 [physics.plasm-ph]. Such magnetic fields enable fast synchrotron radiation cooling of the beam emittance of laser-plasma accelerated leptons. This recent finding opens a novel approach for design of laser-plasma FELs or colliders, where the acceleration stages are interleaved with laser-plasma emittance cooling stages. In this concept paper we present an outline of how a staged plasma-acceleration FEL could look like and discuss further studies needed to investigate the feasibility of the concept in detail.

description: Production material centres around a joint interview conducted with Lorna Wanosts’a7 Williams and Reuven Feuerstein in Shoresh, Isreal. In tape 1, Wanosts’a7 and Feuerstein discuss how she first came to learn of his work while teaching at Ts̓zil Community School; Feuerstein’s conceptualizations of cultural difference and cultural deprivation; the need for respect of cultural differences without devaluing other groups; and Feuerstein’s idea of the forces of belonging. In tape 2, Wanosts’a7 and Feuerstein discuss Wanosts’a7’s experience first coming to Israel for Feuerstein’s international summer workshop; Instrumental Enrichment (FIE); more on cultural difference and cultural deprivation; mediated learning experience and cognitive testing; and the importance of emotional engagement in education, which includes a reflection by Feuerstein’s on his work with children of the Holocaust. In tape 3, Feuerstein discusses the BBC documentary “The Transformers: Out of the Wilderness” created about his work; and the responsibilities of parents in providing mediation, including the importance of Wanosts’a7’s work in re-empowering parents in that role. The filmed segments of the interview run from 12:29 on tape 1, and continue until 14:48 on tape 3. 12:30 on tape 3 to the end of the interview are silent. Additional sequences can be found proceeding and following the interview, including the Old City of Jerusalem; the Western Wall; Shoresh; and the Neve Carmel caravan site in Haifa. Much of this material does not have corresponding audio.

description: We consider a two dimensional random band matrix ensemble, in the limit of infinite volume and fixed but large band width $W$. For this model we rigorously prove smoothness of the averaged density of states. We also prove that the resulting expression coincides with Wigner's semicircle law with a precision $W^{-2+δ},$ where $δ\to 0$ when $W\to \infty.$ The proof uses the supersymmetric approach and extends results by Disertori, Pinson and Spencer from three to two dimensions.

description: Dunkl derivative enriches solutions by discussing parity due to its reflection operator. Very recently, one of the authors of this manuscript presented one of the most general forms of Dunkl derivative that depends on three Wigner parameters to have a better tuning. In this manuscript, we employ the latter generalized Dunkl derivative in a relativistic equation to examine two-dimensional harmonic and anharmonic oscillators solutions. We obtain the solutions by Nikiforov-Uvarov and QES methods, respectively. We show that degenerate states can occur according to the Wigner parameter values.

description: The joint statistical properties of two free energies computed at two different temperatures in {\it the same sample} of $(1+1)$ directed polymers is studied in terms of the replica technique. The scaling dependence of the reduced free energies difference ${\cal F} = F(T_{1})/T_{1} - F(T_{2})/T_{2}$ on the two temperatures $T_{1}$ and $T_{2}$ is derived. In particular, it is shown that if the two temperatures $T_{1} \, < \, T_{2}$ are close to each other the typical value of the fluctuating part of the reduced free energies difference ${\cal F}$ is proportional to $(1 - T_{1}/T_{2})^{1/3}$. It is also shown that the left tail asymptotics of this free energy difference probability distribution function coincides with the corresponding tail of the TW distribution.
