description: The main objective of this study is the characterization of the velocity field in the Cygnus OB1 association using the radial velocity data currently available in the literature. This association is part of a larger star-forming complex located in the direction of the Cygnus region, but whose main subsystems may be distributed at different distances from the sun. We have collected radial velocity data for more than 300 stars in the area of 5 x 5 square degrees centred on the Cygnus OB1 association. We present the results of a kinematic clustering analysis in the subspace of the phase space formed by angular coordinates and radial velocity using two independent methodologies. We have found evidence of structure in the phase space with the detection of two main groups, corresponding to different radial velocity and distance values, belonging to the association, and associated with two main shells defined by the Halpha emission. A third grouping well separated from the other two in velocity appears to occupy the whole region associated with what has been called "common shell".

description: Topologically distinct magnetic structures like skyrmions, domain walls, and the uniformly magnetized state have multiple applications in logic devices, sensors, and as bits of information. One of the most promising concepts for applying these bits is the racetrack architecture controlled by electric currents or magnetic driving fields. In state-of-the-art racetracks, these fields or currents are applied to the whole circuit. Here, we employ micromagnetic and atomistic simulations to establish a concept for racetrack memories free of global driving forces. Surprisingly, we realize that mixed sequences of topologically distinct objects can be created and propagated over far distances exclusively by local rotation of magnetization at the sample boundaries. We reveal the dependence between chirality of the rotation and the direction of propagation and define the phase space where the proposed procedure can be realized. The advantages of this approach are the exclusion of high current and field densities as well as its compatibility with an energy-efficient three-dimensional design.

description: The India-based Neutrino Observatory (INO) collaboration has chosen glass Resistive Plate Chambers (RPCs) as the active detector elements for the Iron Calorimeter (ICAL) experiment. In the present work, we study the electrical properties such as bulk resistivity and relative permittivity of the glasses from two different manufacturers and compared the performances of RPCs built using these glasses. We conclude that the glass electrodes with larger bulk resistivy and permittivity are better suited for manufacturing RPCs for the ICAL experiment, as these detectors could be operated at lower bias currents and voltages, and produce better time resolutions compared to those built with glass electrodes of smaller bulk resistivity and permittivity.

description: Non-small cell lung cancer (NSCLC) is the leading cause of cancer death worldwide underlining the urgent need for new biomarkers and therapeutic targets for this disease. Long noncoding RNAs are critical players in NSCLC but the role of small RNA species is not well understood. In the present study, we investigated the role of H/ACA box small nucleolar RNAs (snoRNAs) and snoRNA-bound ribonucleoproteins (snoRNPs) in the tumorigenesis of NSCLC. H/ACA box snoRNPs including the NOP10 core protein were highly expressed in NSCLC. High levels of either NOP10 mRNA or protein were associated with poor prognosis in NSCLC patients. Loss of NOP10 and subsequent reduction of H/ACA box snoRNAs and rRNA pseudouridylation inhibited lung cancer cell growth, colony formation, migration, and invasion. A focused CRISPR/Cas9 snoRNA knockout screen revealed that genomic deletion of SNORA65, SNORA7A, and SNORA7B reduced proliferation of lung cancer cells. In line, high levels of SNORA65, SNORA7A, and SNORA7B were observed in primary lung cancer specimens with associated changes in rRNA pseudouridylation. Knockdown of either SNORA65 or SNORA7A/B inhibited growth and colony formation of NSCLC cell lines. Our data indicate that specific H/ACA box snoRNAs and snoRNA-associated proteins such as NOP10 have an oncogenic role in NSCLC providing new potential biomarkers and therapeutic targets for the disease.

description: The Art of Mentoring project combines written thesis with creative production to investigate some of the practices of media mentorships in culturally diverse Australia. Current and previous governments have developed programs that support students from culturally diverse groups enrolled in tertiary education media subjects to promote equality of opportunity and increase participation. This practice is intended to support, develop, and ultimately change the current look and feel of local media to reflect more accurately the diversity of Australian culture. There are questions, however, about the principles underpinning these programs and whether they have been sufficiently founded in research. This project addresses the gap in knowledge by asking: What is mentoring? With a substantive definition in hand it goes on t o consider: What, in particular, is media mentoring? What is the role of media mentorships in a culturally diverse Australia ? This project aimed to examine some of these practices of media mentorships in culturally diverse Australia and to highlight the benefits and drawbacks that have led to the successes and failures of mentorship programs locally. The methods used to answer these questions were practice - based enquiry and qualitative critical analysis of existing research. The written thesis builds upon current research that investigates the association between diversity and mentorship in culturally diverse Australia. Accompanying the 10,000 - word thesis is a 10 - minute documentary video interviewing mentors and mentees, exploring some of the ways that mentoring and mentorships have personally influenced their careers. The outcomes of this research are a synthesis of knowledge about general mentoring, highlighting specific roles of culturally diverse media mentoring in Australia; and a video resource documenting insight from successful mentors and mentees. Both offer some foundational guidelines that may support the development of programs locally.

description: Bees and flowering plants are two closely interacting groups of organisms. Habitat loss and fragmentation associated with urbanisation are major threats to both partners. Yet how and why bee and floral richness and diversity co-vary within the urban landscape remain unclear. Here, we sampled bees and flowering plants in urban green spaces to investigate how bee and flowering plant species richness, their phylogenetic diversity and pollination-relevant functional trait diversity influence each other in response to urban fragmentation. As expected, bee abundance and richness were positively related to flowering plant richness, with bee body size (but not bee richness and diversity) increasing with nectar-holder depth of flowering plants. Causal modelling indicated that bottom-up effects dictated patterns of bee-flower relationships, with urban fragmentation diminishing flowering plants richness and thereby indirectly reducing bee species richness and abundance. The close relationship between bees and flowering plants highlights the risks of their parallel declines in response to land-use change within the urban landscape.

description: We review the progress that has been recently made in the application of time-dependent density functional theory to thermoelectric phenomena. As the field is very young, we emphasize open problems and fundamental issues. We begin by introducing the formal structure of \emph{thermal density functional theory}, a density functional theory with two basic variables -- the density and the energy density -- and two conjugate fields -- the ordinary scalar potential and Luttinger's thermomechanical potential. The static version of this theory is contrasted with the familiar finite-temperature density functional theory, in which only the density is a variable. We then proceed to constructing the full time-dependent non equilibrium theory, including the practically important Kohn-Sham equations that go with it. The theory is shown to recover standard results of the Landauer theory for thermal transport in the steady state, while showing greater flexibility by allowing a description of fast thermal response, temperature oscillations and related phenomena. Several results are presented here for the first time, i.e., the proof of invertibility of the thermal response function in the linear regime, the full expression of the thermal currents in the presence of Luttinger's thermomechanical potential, an explicit prescription for the evaluation of the Kohn-Sham potentials in the adiabatic local density approximation, a detailed discussion of the leading dissipative corrections to the adiabatic local density approximation and the thermal corrections to the resistivity that follow from it.

description: Introduction: A rapid and reliable detection of glial fibrillary acidic protein (GFAP) in biological samples could assist in the diagnostic evaluation of neurodegenerative disorders. Sensitive assays applicable in the routine setting are needed to validate the existing GFAP tests. This study aimed to develop a highly sensitive and clinically applicable microfluidic immunoassay for the measurement of GFAP in blood. Methods: A microfluidic GFAP assay was developed and validated regarding its performance. Subsequently, serum and cerebrospinal fluid (CSF) of Alzheimer’s disease (AD), Multiple Sclerosis (MS) and control patients were analyzed with the established assay, and levels were compared to the commercial GFAP Simoa discovery kit. Results: The developed GFAP assay showed a good performance with a recovery of 85% of spiked GFAP in serum and assay variations below 15%. The established assay was highly sensitive with a calculated lower limit of quantification and detection of 7.21 pg/mL and 2.37 pg/mL, respectively. GFAP levels were significantly increased in AD compared to control patients with advanced age (p = 0.002). However, GFAP levels revealed no significant increase in MS compared to control patients in the same age range (p = 0.140). Furthermore, serum GFAP levels evaluated with the novel microfluidic assay strongly correlated with Simoa concentrations (r = 0.88 (95% CI: 0.81–0.93), p < 0.0001). Conclusion: We successfully developed a sensitive and easy-to-use microfluidic assay to measure GFAP in blood. Furthermore, we could confirm previous findings of elevated GFAP levels in AD by applying the assay in a cohort of clinically characterized patients.

description: The Queensland fruit fly (Qfly) Bactrocera tryoni is a major pest of Australian horticulture. A Sterile Insect Technique is being developed to control Qfly but remating of females with wild males could undermine its success. In Qfly, the transfer of seminal fluid during mating influences the remating propensity of females. However, the protein and peptide composition of Qfly seminal fluid has not been characterised. This thesis presents a proteomic analysis of Qfly seminal fluid to identify candidate peptides for sexual inhibition. It characterises the reproductive gland proteomes of sexually mature virgin males, which possess full gland contents, just-mated males of the same age whose gland contents have been transferred to their mates, and males dissected 13–16.5 hours after mating whose gland contents should be substantially replenished. I find 63 candidate seminal fluid proteins, 21 of which could be sufficiently annotated. I do not find homologues of the Sex Peptide responsible for remating inhibition in Drosophila melanogaster, but I do find matches to other peptide hormones. I also find several proteases, other post-translational protein modifying enzymes, and ligand-binding proteins, some number of which could be responsible for activation and transport of prohormones to their receptors in the female.

description: The School Entry Examination (SEE) can be used to identify children with current health issues, developmental delays, and risk factors for later diseases. This study analyzes the health status of preschool children in a German city with considerable socio-economic differences among its quarters. We used secondary data from SEEs 2016–2019 from the entire city (8417 children), which we divided into quarters with low (LSEB), medium (MSEB), and high socioeconomic burden (HSEB). In HSEB quarters, 11.3% of children were overweight as opposed to 5.3% in LSEB quarters. In HSEB quarters, 17.2% of children had sub-par cognitive development in contrast to 1.5% in LSEB quarters. For overall sub-par development, LSEB quarters had a prevalence of 3.3%, whereas, in HSEB quarters, 35.8% of children received this result. Logistic regression was used to determine the influence of the city quarter on the outcome of overall sub-par development. Here, considerable disparities among HSEB and LSEB quarters remained after adjustment for parents’ employment status and education. Pre-school children in HSEB quarters showed a higher risk for later disease than children in LSEB quarters. The city quarter had an association with child health and development that should be considered in the formulation of interventions.

Journalists, media diplomacy and media-broker diplomacy in relations between mainland China and Taiwan from 1987-2009

Subjects: Other education not elsewhere classified

description: The focus of this thesis is the role of journalists, members of cultural and intellectual elites in their own societies, in the expansion of cross-strait relations between mainland China and Taiwan and the sociopolitical transformations that envelope these relations. Since 1949, the knotty relations between these two societies have been characterised by long-standing political and military confrontation, diplomatic competition and more recently, economic cooperation. -- The thesis aims at analysing the role of journalists on both sides in brokering, from 1987, friendlier relations between mainland China and Taiwan, through what has been characterised in the literature as media-broker diplomacy and media diplomacy, diplomacy being a process of negotiation that can contribute to conflict resolution or advancement of cooperation in social contexts at all levels. This thesis proposes that cross-strait relations are a process of communication within which the media acts as the indicator of the political climate and journalists in particular have been important actors in constructing a peaceful climate. Historically journalists have been instrumental in improving crossstrait relations at times and at other times media has ratcheted up animosity. However, their role as mediators has been achieved at the cost of journalistic independence and neutrality. -- To explore this research proposition, this thesis employs case studies and intensive interviews as two key research methods. From an historical perspective, this thesis delineates the trajectories of mediabroker diplomacy and media diplomacy in the cross-strait setting (1987-2009). From an international communication perspective, however, it proceeds with a theoretical investigation of journalists' concerns about mediating at the crossroads of media and politics, journalistic independence and political participation, professionalism and nationalism. -- The significance of this thesis is that it will provide an objective assessment of media diplomacy and media-broker diplomacy in one of the most difficult flash points in the world, providing as an outcome a detailed reconstruction and analysis of the process of media diplomacy and media-broker diplomacy in this context, which would be available as a model for consideration in other contexts.

description: We describe the evolution of optical and X-ray temporal characteristics during the outburst decline of the black hole X-ray binary SWIFT J1753.5-0127. The optical/X-ray cross-correlation function demonstrates a single positive correlation at the outburst peak, then it has multiple dips and peaks during the decline stage, which are then replaced by the precognition dip plus peak structure in the outburst tail. Power spectral densities and phase lags show a complex evolution, revealing the presence of intrinsically connected optical and X-ray quasi-periodic oscillations. For the first time, we quantitatively explain the evolution of these timing properties during the entire outburst within one model, the essence of which is the expansion of the hot accretion flow towards the tail of the outburst. The pivoting of the spectrum produced by synchrotron Comptonization in the hot flow is responsible for the appearance of the anti-correlation with the X-rays and for the optical quasi-periodic oscillations. Our model reproduces well the cross-correlation and phase lag spectrum during the decline stage, which could not be understood with any model proposed before.

We develop a theoretical model of wavefront shaping through a multimode fiber and use it to confirm our experimental results and analyze the nature of the focal distortions. We show that aberration-free imaging with a large field of view can be achieved by using an appropriate number of segments on the spatial light modulator during the wavefront-shaping procedure. The results describe aberration limits for imaging with multimode fibers as in, e.g., microendoscopy.

description: Cancer neoantigens that arise from somatic mutations have emerged as important targets for personalized immunization. Here, we report an improved overall survival of a HER2-positive metastatic breast cancer patient using a bioinformatic-based personalized peptide immunization called BITAP (BioInformatic Tumor Address Peptides). The epitopes were predicted using our in-house bioinformatic pipeline, and the immunogenicity was tested by IFN-γ ELISPOT and intracellular cytokine staining assays. In total, a significant peptide-specific T-cell response was detected against 18 out of the 76 (≈24%) tested peptides. The patient’s follow-up by measuring serologic markers showed a significant reduction in the tumor marker levels following BITAP immunization. Along with standard treatment, the patient treated with the BITAP showed stable disease with a remarkably improved overall survival, and no serious treatment-related adverse effects. In conclusion, our findings suggest that BITAP immunization is feasible, and safe, and may induce tumor regressions in patients with HER2-positive subsets of breast cancer.

description: In this paper we describe the design and validation of a virtual fitness environment aiming at keeping older adults physically and socially active. We target particularly older adults who are socially more isolated, physically less active, and with less chances of training in a gym. The virtual fitness environment, namely Gymcentral, was designed to enable and motivate older adults to follow personalised exercises from home, with a (heterogeneous) group of remote friends and under the remote supervision of a Coach. We take the training activity as an opportunity to create social interactions, by complementing training features with social instruments. Finally, we report on the feasibility and effectiveness of the virtual environment, as well as its effects on the usage and social interactions, from an intervention study in Trento, Italy
Design and analysis of human identification protocols

Publisher: name: Macquarie University

description: Human identification protocols are authentication protocols that enable a human using an insecure terminal to authenticate to a remote server. The goal of such protocols is to ensure secure authentication in the presence of an adversary who can not only view the user's inputs, and the internal computations and display of the terminal, but also eavesdrop on the communication link between the terminal and the server. An active adversary can in addition actively interfere with this communication link. However, protocols secure against active adversaries fall well short of usability. As a result, the focus of recent research has been on security against passive adversaries. Traditional authentication methods such as password-based authentication are not secure under this model, since the adversary can impersonate the user by learning the user's password after observing a single authentication session. -- Since the introduction of the problem by Matsumoto and Imai in 1991, there have been sporadic attempts at constructing secure human identification protocols. However, to date there is no accepted solution, mainly because such protocols require mental computations from humans, and therefore the tradeoff between security and usability is huge. State-of-the-art protocols take between one to three minutes for authentication, but guarantee stronger security than traditional authentication methods. While this authentication time is not acceptable for most practical purposes, many interesting new mathematical problems and ideas have resulted in search for usable protocols. -- This thesis aims to further the research in human identification protocols by focusing on the mathematical and analytical aspects of such protocols. We generalize some aspects of these protocols by analyzing their general structure. We give detailed security analysis of two protocols from literature, showing that without a thorough security analysis, these protocols are vulnerable to simple but innovative attacks. We also give the construction of two protocols with detailed security analysis and clearly defined design goals. Finally, we analyze the link between fixed-parameter intractability and human identification protocols. It is suggested that problems that are fixed-parameter intractable can be natural candidates for primitives in human identification protocols.
The Observable Signatures of GRB Cocoons

description: As a long GRB jet propagates within the surrounding stellar atmosphere it creates a cocoon composed of an outer Newtonian shocked stellar material and an inner (possibly relativistic) shocked jet material. The jet deposits $10^{51}-10^{52}$ erg into this cocoon. This energy is comparable to the GRB's energy and to the energy of the accompanying supernova, yet its signature has been largely neglected so far. A fraction of the cocoon energy is released during its expansion following the breakout from the star and later as it interacts with the surrounding matter. We explore here the possible signatures of the cocoon emission and outline a framework to calculate them from the conditions of the cocoon at the time of the jet breakout. We show that the cocoon signature depends strongly on the level of mixing between the shocked jet and shocked stellar material that fills it, which is currently unknown. We find that if there is no mixing at all then the $γ$-ray emission from the cocoon is so bright that it should have been already detected, and the lack of such detections indicates that mixing at some level must take place. We calculate also the expected signal for partial and full mixing. While the typical signals are weaker than GRBs' afterglows, the latter are highly beamed while the former have wide angles. We predict that future optical, UV and X-ray transient searches, like LSST, ZTF, ULTRASAT, ISS-Lobster and others will most likely detect such signals, providing a wealth of information on the progenitors and jets of GRBs. While we focus on long GRBs, we note that analogous (but weaker) cocoons may arise in short GRBs as well. Their signatures might be the most promising electromagnetic counterparts for gravitational waves merger's signals.

description: Dalbergia melanoxylon Guill. & Perr (Fabaceae) is widely utilized in the traditional medicine of East Africa, showing effects against a variety of ailments including microbial infections. Phytochemical investigation of the root bark led to the isolation of six previously undescribed prenylated isoflavanones together with eight known secondary metabolites comprising isoflavanoids, neoflavones and an alkyl hydroxylcinnamate. Structures were elucidated based on HR-ESI-MS, 1- and 2-D NMR and ECD spectra. The crude extract and the isolated compounds of D. melanoxylon were tested for their antibacterial, antifungal, anthelmintic and cytotoxic properties, applying established model organisms non-pathogenic to humans. The crude extract exhibited significant antibacterial activity against Gram-positive Bacillus subtilis (97% inhibition at 50 μg/mL) and antifungal activity against the phytopathogens Phytophthora infestans, Botrytis cinerea and Septoria tritici (96, 89 and 73% at 125 μg/mL, respectively). Among the pure compounds tested, kenusanone H and (3R)-tomentosanol B exhibited, in a panel of partially human pathogenic bacteria and fungi, promising antibacterial activity against Gram-positive bacteria including methicillin-resistant Staphylococcus aureus (MRSA) and Mycobacterium showing MIC values between 0.8 and 6.2 μg/mL. The observed biological effects support the traditional use of D. melanoxylon and warrant detailed investigations of its prenylated isoflavanones as antibacterial lead compounds.

description: Xerostomia is the phenomenon of dry mouth and is mostly caused by hypofunction of the salivary glands. This hypofunction can be caused by tumors, head and neck irradiation, hormonal changes, inflammation or autoimmune disease such as Sjögren’s syndrome. It is associated with a tremendous decrease in health-related quality of life due to impairment of articulation, ingestion and oral immune defenses. Current treatment concepts mainly consist of saliva substitutes and parasympathomimetic drugs, but the outcome of these therapies is deficient. Regenerative medicine is a promising approach for the treatment of compromised tissue. For this purpose, stem cells can be utilized due to their ability to differentiate into various cell types. Dental pulp stem cells are adult stem cells that can be easily harvested from extracted teeth. They can form tissues of all three germ layers and are therefore becoming more and more popular for tissue engineering. Another potential benefit of these cells is their immunomodulatory effect. They suppress proinflammatory pathways of lymphocytes and could therefore probably be used for the treatment of chronic inflammation and autoimmune disease. These attributes make dental pulp stem cells an interesting tool for the regeneration of salivary glands and the treatment of xerostomia. Nevertheless, clinical studies are still missing. This review will highlight the current strategies for using dental pulp stem cells in the regeneration of salivary gland tissue.

Length dependence of thermal conductivity by approach-to-equilibrium molecular dynamics

description: The length dependence of the thermal conductivity over more than two decades is systematically studied for a range of materials, interatomic potentials and temperatures, by the atomistic approach-to-equilibrium molecular dynamics method (AEMD). By comparing the values of conductivity obtained for a given supercell length and maximum phonon mean-free-path (MFP), we find that such values are strongly correlated, demonstrating that the AEMD calculation with a supercell of finite length, actually probes the thermal conductivity corresponding to a maximum phonon MFP. As a consequence, the less pronounced length dependence usually observed for poorer thermal conductors, such as amorphous silica, is physically justified by their shorter average phonon MFP. Finally, we compare different analytical extrapolations of the conductivity to infinite length, and demonstrate that the frequently used Matthiessen rule is not applicable in AEMD. An alternative extrapolation more suitable for transient-time, finite-supercell simulations is derived. This approximation scheme can also be used to classify the quality of different interatomic potential models with respect to their capability of predicting the experimental thermal conductivity.

description: We derive the spectrum and the total cross section of electromagnetic $e^{+}e^{-}$ pair production in the collisions of two nuclei at low relative velocity $β$. Both free-free and bound-free $e^{+}e^{-}$ pair production is considered. The parameters $η_{A,B}=Z_{A,B}α$ are assumed to be small compared to unity but arbitrary compared to $β$ ($Z_{A,B}$ are the charge numbers of the nuclei and $α$ is the fine structure constant). Due to a suppression of the Born term by high power of $β$, the first Coulomb correction to the amplitude appears to be important at $η_{A,B}\gtrsim β$. The effect of a finite nuclear mass is discussed. In contrast to the result obtained in the infinite nuclear mass limit, the terms $\propto M^{-2}$ are not suppressed by the high power of $β$ and may easily dominate at sufficiently small velocities.

description: Interventions in the human germline, whether for purposes of therapy for a hereditary disease or for purposes of enhancement, are controversial. While enhancement is almost unanimously rejected, therapy-oriented intervention is not a priori regarded as unacceptable. The legal discussion so far has focused primarily on the questions of whether manipulation of the embryo’s germline is permissible or whether the genetic manipulation of germ cells and the use of these germ cells for embryo generation is permissible. Up to now, the upstream questions regarding the systematic germline therapy development in clinical trials have been ignored, including questions as to whether the development of germline therapy would be legally permissible within the European Union framework of clinical studies. This article highlights the legal issues connected with the clinical development of germline intervention, provides an overview of the various answers to these legal questions, and indicates where further research and discussion are needed.

description: Radio emission observations from the Learmonth and Bruny Island radio spectrographs are analysed to determine the nature of a train of discrete, periodic radio \lq sparks\rq (finite-bandwidth, short-duration isolated radio features) which precede a type II burst. We analyse extreme ultraviolet (EUV) imaging from SDO/AIA at multiple wavelengths and identify a series of quasi-periodic rapidly-propagating enhancements, which we interpret as a fast wave train, and link these to the detected radio features. The speeds and positions of the periodic rapidly propagating fast waves and the coronal mass ejection (CME) were recorded using running-difference images and time-distance analysis. From the frequency of the radio sparks the local electron density at the emission location was estimated for each. Using an empirical model for the scaling of density in the corona, the calculated electron density was used to obtain the height above the surface at which the emission occurs, and the propagation velocity of the emission location. The period of the radio sparks, $δt_\mathrm{r}$=1.78$\pm$0.04 min, matches the period of the fast wave train observed at 171 $Å$, $δt_\mathrm{EUV}$=1.7 $\pm$ 0.2 min. The inferred speed of the emission location of the radio sparks, 630 km s$^{-1}$, is comparable to the measured speed of the CME leading edge, 500 km s$^{-1}$, and the speeds derived from the drifting of the type II lanes. The calculated height of the radio emission (obtained from the density) matches the observed location of the CME leading edge. From the above evidence we propose that the radio sparks are caused by the quasi-periodic fast waves, and the emission is generated as they catch up and interact with the leading edge of the CME.
