description: We present an operator-algebraic approach to the quantization and reduction of lattice field theories. Our approach uses groupoid C*-algebras to describe the observables and exploits Rieffel induction to implement the quantum gauge symmetries. We introduce direct systems of Hilbert spaces and direct systems of (observable) C*-algebras, and, dually, corresponding inverse systems of configuration spaces and (pair) groupoids. The continuum and thermodynamic limit of the theory can then be described by taking the corresponding limits, thereby keeping the duality between the Hilbert space and observable C*-algebra on the one hand, and the configuration space and the pair groupoid on the other. Since all constructions are equivariant with respect to the gauge group, the reduction procedure applies in the limit as well.

description: The ways we represent our relationships, notice our partners, and let the social media interfere in our romantic relationships have aroused researchers’ interest. In this research, the purpose was to analyze, how people who use social media actively perceive the connection between social media and romantic relationships. The research questions set for this study were: (1) What are the rules of self-disclosure that support romantic relationships in social media?; (2) What kinds of benefits do social media provide for romantic relationships?; and (3) What kinds of threats or disadvantages do social media provide for romantic relationships? This was a qualitative research in which the research participants (N=25) were approached with an online questionnaire that included open-ended questions. The answers were analyzed with the qualitative content analyzing method. The findings showed that the research participants could name some principles of self-disclosure regarding their romantic relationships in social media and certain benefits as well as harms and threats of social media for a romantic relationship. The findings were further discussed in the light of the elements of love as emotions, love as actions, and love as skills and knowledge that here could be interpreted as “the media literacy of romantic relationships”.

description: Background: The transcription factor CCAAT/enhancer-binding protein β (C/EBPβ) is implicated in diverse processes and diseases. Its two isoforms, namely liver-enriched activator protein (LAP) and liver-enriched inhibitor protein (LIP) are translated from the same mRNA. They share the same C-terminal DNA binding domain except LAP has an extra N-terminal activation domain. Probably due to its higher affinity for its DNA cognate sequences, LIP can inhibit LAP transcriptional activity even at substoichiometric levels. However, the regulatory mechanism of C/EBPβ gene expression and the LAP: LIP ratio is unclear. Methods: In this study, the C/EBPβ promoter sequence was scanned for conserved P53 response element (P53RE), and binding of P53 to the C/EBPβ promoter was tested by Electrophoretic Mobility Shift Assay (EMSA) and chromatin immunoprecipitation assay. P53 over-expression and dominant negative P53 expression plasmids were transfected into rat lung fibroblasts and tested for C/EBPβ gene transcription and expression. Western blot analysis was used to test the regulation of C/EBPβ LAP and LIP isoforms. Constructs containing the LAP 5′untranslated region (5′UTR) or the LIP 5′UTR region were used to test the importance of 5′UTR in the control of C/EBPβ LAP and LIP translation. Results: The C/EBPβ promoter sequence was found to contain a conserved P53 response element (P53RE), which binds P53 as demonstrated by Electrophoresis Mobility Shift Assay and chromatin immunoprecipitation assays. P53 over-expression suppressed while dominant negative P53 stimulated C/EBPβ gene transcription and expression. Western blot analysis showed that P53 differentially regulated the translation of the C/EBPβ LAP and LIP isoforms through the regulation of eIF4E and eIF4E-BP1. Further studies with constructs containing the LAP 5′untranslated region (5′UTR) or the LIP 5′UTR region showed that the 5′UTR is important in differential control of C/EBPβ LAP and LIP translation. Conclusion: Analysis of the effects of P53 on C/EBPβ expression revealed a novel mechanism by which P53 could antagonize the effects of C/EBPβ on its target gene expression. For the first time, P53 is shown to be a repressor of C/EBPβ gene expression at both transcriptional and translational levels, with a differential effect in the magnitude of the effect on LAP vs. LIP isoforms.

description: We present a theoretical study of the charging effects in single and double layer black phosphorus quantum dots (BPQDs) with lateral sizes of 2 nm and 3 nm. We demonstrate that the charging of BPQDs are able to store up to an $N_{max}$ electron (that depends on the lateral size and number of layers in the QD), after which structural instabilities arises. For example, 3 nm wide hydrogen-passivated single layer BPQDs can hold a maximum of 16 electrons, and an additional electron causes the expelling of hydrogen atoms from the QD borders. We also calculated the additional energy ($E_A$) spectrum. For single layer QDs with 2 and 3 nm of lateral sizes, the average $E_A$ is around 0.4 eV and 0.3 eV, respectively. For double layer QDs with the same sizes, the average $E_A$ is around 0.25 eV and 0.2 eV, respectively.

description: MicroRNAs (miRNAs) are short (~22 nucleotide long) single-stranded noncoding RNAs that regulate gene expression post-transcriptionally in the RNA-induced silencing complex (RISC). miRNAs play an important role in immune cell function and affect many aspects of T cell immunity. Activation of naive T cells induces dramatic changes in the expression of miRNAs and RISC-associated proteins. We studied these changes in expression of miRNAs in CD8+ T cells using the OT-I transgenic T-cell receptor (TCR) mouse model, in which all T cells are CD8+ and respond to ovalbumin peptides. Upon in vitro activation, we saw dynamic changes in the expression of individual miRNAs, which were influenced by whether the T cells responded to high or low affinity peptides and whether they were differentiating to effector or memory cells. It was recently shown that in naive T cells, miRNAs are predominantly found in a low molecular weight (LMW) RISC composed of Argonaute (Ago)-proteins and miRNAs. Upon activation of T cells, biologically active miRNAs interacting with their target messenger RNAs (mRNAs) were shown to redistribute to a high molecular weight (HMW) RISC, which additionally contains RNA metabolism factors and Ago-interacting proteins such as GW182. We followed the development of HMW and LMW complexes in activated CD8⁺ T cells in order to determine their role and to identify the miRNAs and their targets present in both. We confirmed that GW182 protein was induced upon CD8⁺ T cell activation and associated with Ago-2, forming HMW complexes. To study the distribution of miRNAs between HMW and LMW RISC, we undertook small RNA sequencing of the associated miRNAs. From these data we identified specific miRNAs that were enriched in HMW RISC in activated CD8⁺ T cells. We also found that miRNA abundance did not always reflect its association with HMW RISC. Lastly, to discover miRNA targets, we used a novel method called cross-linking, ligation and sequencing of hybrids (CLASH), which directly identifies miRNAs and their targets by immunoprecipitation of RISC and RNA sequencing. From these data we found potential novel targets for key miRNAs in CD8⁺ T cells. Expanding our knowledge of the role of miRNAs in T cell activation beyond observations of miRNA expression changes, by focusing on biologically active miRNAs and their targets in HMW RISC will deepen our understanding of the mechanism of action of miRNAs as well as the signalling pathways surrounding T cell activation.

An orientation to nature: the construction of wilderness in the work of John Watt Beattie
Creators: name: Hore, Jarrod Ray
Publisher: name: Macquarie University

Subjects: Other education not elsewhere classified

description: At the turn of the twentieth century Australian nature had become increasingly bound up in the symbolism of a young nation. From the appropriation of native flora and fauna to the declaration of National Parks, the hostility that defined much of the early interactions between Europeans and Australian nature had softened. This thesis examines the reorientations to nature that preceded this moment by investigating a new vision of nature in Tasmania at the turn of the twentieth century. This vision was embodied in the sentimental depictions of remote wilderness that the photographer John Watt Beattie popularised between 1879 and 1930. The trends and values embodied in Beattie’s photography — those of Tasmanian history, the emergence of a sentimental attachment to local scenery and romanticism — communicated an orientation to nature based on sympathy, wonder and respect. By identifying how Beattie played upon the anxieties of his Tasmanian audiences, performed his role as a photographer-explorer and reproduced discourses of romanticism, this thesis explores the archaeology of an emergent environmental consciousness in turn of the century Tasmania.
Pre-service teachers' noticing of structural thinking in mathematics

description: The importance of teachers' understanding and using mathematical structure is recognised but not well researched. Mathematical structure, when understood, connects mathematical concepts and builds powerful understandings of deep mathematical thinking. The research reported in this thesis is based on the premise that educating teachers to consider structural thinking in their teaching and learning processes will improve their mathematical content and pedagogical knowledge. The positive outcome of teachers using mathematical structure is that it encourages students to think structurally. In this study, I investigated two primary and three secondary mathematics pre-service teachers (PSTs) as they engaged in learning about mathematical structure through a professional learning program during their final undergraduate year. This study comprised two phases. The first phase involved the primary PSTs, the second involved the secondary mathematics PSTs. All PSTs completed an introductory and exit questionnaire either side of a professional learning program in which they participated in three cycles, each of which comprised a professional learning workshop, teaching a planned mathematics lesson, and a post-lesson interview or post-lesson reflection. Quantitative and qualitative data were collected from the two questionnaires, audio transcripts of the professional learning workshops and the post-lesson interviews, lesson plans, and videos of the PSTs' mathematics lessons. These data were analysed for the PSTs' understanding and use of a new framework, the Connecting, Recognising Patterns,Identifying Similarities and Differences, Generalising and Reasoning (CRIG) framework, to teach mathematical structure-a framework that refers to "noticing structural thinking". From the results of this study, I was able to identify that the PSTs came to appreciate the importance of mathematical structure through their familiarity with the new framework. Engaging in the CRIG framework proved to be effective in deepening the PSTs' mathematical content and pedagogical knowledge. However, their use of the CRIG framework when in-the-moment of teaching was not always reflected in their communications or pedagogical approach -- summary.

description: Recent results using radial-velocity measurements from the Gaia-ESO Survey have led to the discovery of multiple kinematic populations across the Vela OB2 association. We present here a proper-motion study of the same region. Our aim is to test whether the radial-velocity populations have a counterpart in proper-motion space, and if so, how the two sets of kinematical data complement each other. This work is based on parallaxes and proper motions from the TGAS catalog, as part of Gaia DR1. Two distinct proper-motion populations are found dispersed across ~5 degrees (or ~30 pc at their likely distances). Their detailed correspondence to the radial-velocity populations could not be tested, because of the paucity of common objects. However, compelling indications are found that one of the new proper-motion populations consists mostly of members of the young cluster NGC 2547, and the other is related to the gamma Vel cluster. Constraints on the age of the two populations, both of which appear to be only 10-35 Myr old, and their possible mutual interactions within the last 1.5 Myrs, are discussed.

description: The \emph{community}, the assemblage of organisms co-existing in a given space and time, has the potential to become one of the unifying concepts of biology, especially with the advent of high-throughput sequencing experiments that reveal genetic diversity exhaustively. In this spirit we show that a tool from community ecology, the Rank Abundance Distribution (RAD), can be turned by the new MaxRank normalization method into a generic, expressive descriptor for quantitative comparison of communities in many areas of biology. To illustrate the versatility of the method, we analyze RADs from various \emph{generalized communities}, i.e.\ assemblages of genetically diverse cells or organisms, including human B cells, gut microbiomes under antibiotic treatment and of different ages and countries of origin, and other human and environmental microbial communities. We show that normalized RADs enable novel quantitative approaches that help to understand structures and dynamics of complex generalize communities.
Learning to find a gap: navigational problem solving in nocturnal bull ants

description: Solitarily foraging ant species derive compass information from terrestrial landmarks and path integration to navigate. Our test ants, solitary foragers of Myrmecia midas, have the added challenge of completing their navigation during evening and morning twilight. The aim of this research was to test bull ants’ ability to use edge contrast to find a gap in an obstacle that obstructs their direct path. Ants were individually identified and tested repeatedly on their foraging trip. An artificial obstacle (0.9m by 1.2m wide) with a 10cm gap in it was installed on their foraging route to train them to find the gap. The gap location was unpredictably varied from one run to another so that the ants had to look for it. In training, each nest of ants was given two colour conditions on the obstacles: one with black on one side of the gap and white on the other side (which was easier to spot), one with black on both sides (which was harder to spot). We tested the ants’ ability to find the gap and measured the directness of the path. We found that the ants learnt to find the gap in the obstacle after completing several trials. However, we did not find any significant differences in the ants’ behaviour in the two colour conditions.

description: Multicomponent protein–RNA complexes comprising a ribonuclease and partner RNA helicase facilitate the turnover of mRNA in all domains of life. While these higher-order complexes provide an effective means of physically and functionally coupling the processes of RNA remodeling and decay, most ribonucleases and RNA helicases do not exhibit sequence specificity in RNA binding. This raises the question as to how these assemblies select substrates for processing and how the activities are orchestrated at the precise moment to ensure efficient decay. The answers to these apparent puzzles lie in the auxiliary components of the assemblies that might relay decay-triggering signals. Given their function within the assemblies, these components may be viewed as “sensors.” The functions and mechanisms of action of the sensor components in various degradation complexes in bacteria and eukaryotes are highlighted here to discuss their roles in RNA decay processes.
A new integrated symmetrical table for genetic codes

description: Degeneracy is a salient feature of genetic codes, because there are more codons than amino acids. The conventional table for genetic codes suffers from an inability of illustrating a symmetrical nature among genetic base codes. In fact, because the conventional wisdom avoids the question, there is little agreement as to whether the symmetrical nature actually even exists. A better understanding of symmetry and an appreciation for its essential role in the genetic code formation can improve our understanding of nature coding processes. Thus, it is worth formulating a new integrated symmetrical table for genetic codes, which is presented in this paper. It could be very useful to understand the Nobel laureate Crick wobble hypothesis: how one transfer ribonucleic acid can recognize two or more synonymous codons, which is an unsolved fundamental question in biological science.

description: A set of Smoothed Particle Hydrodynamics simulations of the influence of photoionising radiation and stellar winds on a series of 10$^{4}$M$_{\odot}$ turbulent molecular clouds with initial virial ratios of 0.7, 1.1, 1.5, 1.9 and 2.3 and initial mean densities of 136, 1135 and 9096\,cm$^{-3}$ are presented. Reductions in star formation efficiency rates are found to be modest, in the range $30\%-50\%$ and to not vary greatly across the parameter space. In no case was star formation entirely terminated over the $\approx3$\,Myr duration of the simulations. The fractions of material unbound by feedback are in the range $20-60\%$, clouds with the lowest escape velocities being the most strongly affected.\\ Leakage of ionised gas leads to the HII regions rapidly becoming underpressured. The destructive effects of ionisation are thus largely not due to thermally--driven expansion of the HII regions, but to momentum transfer by photoevaporation of fresh material. Our simulations have similar global ionisation rates and we show that the effects of feedback upon them can be adequately modelled as a steady injection of momentum, resembling a momentum--conserving wind.

description: Η πτυχιακή εργασία «Βιομηχανική περιοχή του Πειραιά» που ακολουθεί πραγματεύεται την αποτύπωση ενός μικρού μέρους από την βιομηχανική περιοχή του Πειραιά. Περιλαμβάνεται από δισέλιδα που περιγράφουν αρχιτεκτονικές δομές. Μέσα από τις δομές, μπορεί κάποιος να διακρίνει τις λεπτομέρειες των κατασκευών από τα εργοστάσια παραγωγής και τις αποθήκες, οι οποίες έχουν μια συγκεκριμένη ομοιότητα που χαρακτηρίζει την αρχιτεκτονική της βιομηχανικής αυτής ζώνης. Παρόλα αυτά διαφοροποιούνται ελάχιστα ως προς τα χρώματα, την υφή και την ταυτότητα τους. Η εργασία πραγματοποιήθηκε στο μεγάλο διάστημα της πανδημίας και του επερχόμενου lockdown, το οποίο είχε μεγάλη επιρροή στην ψυχολογική μου κατάσταση και συνεπώς στον τρόπο που προσέγγιζα τα γεγονότα. Το συναίσθημα της αποκοπής από την πραγματικότητα, την κανονικότητα και η αναζήτηση «ησυχίας» από την βαβούρα του αστικού περιβάλλοντος, με οδήγησαν στην περιοχή αυτή. Με την αφαιρετική διάθεση που επικρατεί κυρίως στο πρώτο και βασικό μέρος της εργασίας και την έλλειψη ανθρώπινης παρουσίας, προσπαθώ να εντάξω τις εικόνες στο υποσυνείδητο (δηλαδή σε μια ψυχολογική κατάσταση). Αυτό, συσχετίζεται με τον όρο της αισθητικής «Liminal Space» (οριακός χώρος) και αποτελεί ένα σχόλιο μιας μετάβασης από την μια πραγματικότητα στην άλλη.

description: Online learning with streaming data in a distributed and collaborative manner can be useful in a wide range of applications. This topic has been receiving considerable attention in recent years with emphasis on both single-task and multitask scenarios. In single-task adaptation, agents cooperate to track an objective of common interest, while in multitask adaptation agents track multiple objectives simultaneously. Regularization is one useful technique to promote and exploit similarity among tasks in the latter scenario. This work examines an alternative way to model relations among tasks by assuming that they all share a common latent feature representation. As a result, a new multitask learning formulation is presented and algorithms are developed for its solution in a distributed online manner. We present a unified framework to analyze the mean-square-error performance of the adaptive strategies, and conduct simulations to illustrate the theoretical findings and potential applications.

description: Known elicitors of plant defenses against eggs of herbivorous insects are low-molecular-weight organic compounds associated with the eggs. However, previous studies provided evidence that also proteinaceous compounds present in secretion associated with eggs of the herbivorous sawfly Diprion pini can elicit defensive responses in Pinus sylvestris. Pine responses induced by the proteinaceous secretion are known to result in enhanced emission of (E)-β-farnesene, which attracts egg parasitoids killing the eggs. Here, we aimed to identify the defense-eliciting protein and elucidate its function. After isolating the defense-eliciting protein from D. pini egg-associated secretion by ultrafiltration and gel electrophoresis, we identified it by MALDI-TOF mass spectrometry as an annexin-like protein, which we named ‘diprionin’. Further GC-MS analyses showed that pine needles treated with heterologously expressed diprionin released enhanced quantities of (E)-β-farnesene. Our bioassays confirmed attractiveness of diprionin-treated pine to egg parasitoids. Expression of several pine candidate genes involved in terpene biosynthesis and regulation of ROS homeostasis was similarly affected by diprionin and natural sawfly egg deposition. However, the two treatments had different effects on expression of pathogenesis-related genes (PR1, PR5). Diprionin is the first egg-associated proteinaceous elicitor of indirect plant defense against insect eggs described so far.

description: Newly synthesised receptor Bis-(1,3-diphenyl-pyrazolyl methylene acetohydrazide)Calix[4]arene (DPPMACA) was evaluated for cation binding ability. The receptor DPPMACA selectively interact with Zn2+ metal ion as assessed through UV-visible spectroscopy with a bathochromic shift of 14 nm but gave negligible response for other metal cations used as their sulfates. The stoichiometry observed as 1:1 with stability constant 6.438 × 103 M−1. Additionally, computational visions were concentrated for studying the stability and spectroscopic analysis of the DPPMACA-Zn2+ complex using docking, molecular dynamics simulations and density functional theory (DFT) along with time-dependent density functional theory (TD-DFT). The calculations significantly supplement the findings and elucidate the structural geometry and mode of interactions in supramolecular complexation. Herein, we witnessed that DPPMACA was selectively stabilized by Metal-donor and Metal-acceptor contacts with Zn2+ to generate a low-energy complex. These findings are of wide interest, especially because Zn2+ is a well-known biological important cation.

description: In this article, we consider two proper double splittings satisfying certain conditions, of a semi-monotone rectangular matrix A and derive new comparison results for the spectral radii of the correspond ing iteration matrices. These comparison results are useful to analyse the rate of convergence of the iterative methods (formulated from the double splittings) for solving rectangular linear system Ax = b.

description: Η παρούσα διπλωματική εργασία περιγράφει την προσπάθεια μιας ελληνικής μικρομεσαίας επιχείρησης να επιβιώσει συνάπτοντας στρατηγική συμμαχία μέσω της συμφωνίας παραχώρησης δικαιωμάτων εκμετάλλευσης (licensing) με κατασκευαστικό οίκο του εξωτερικού. H υπό εξέταση ελληνική εταιρία MAS Α.Ε. προχώρησε στη σύναψη στρατηγικής συμμαχίας με την εταιρία Woodward στην προσπάθειά της να διεθνοποιηθεί. Στόχος της παρούσας διπλωματικής εργασίας είναι η βιβλιογραφική έρευνα γύρω από τις στρατηγικές συμμαχίες ως μέθοδοι διεθνοποίησης και επίτευξης υψηλής ανταγωνιστικότητας. Μέσα από αυτήν αναλύονται οι λόγοι που οδήγησαν την εταιρία MAS Α.Ε να διεθνοποιηθεί καθώς και οι λόγοι για τους οποίους επέλεξε για σύμμαχο σε αυτήν της την προσπάθεια την εταιρία Woodward. Αναλύονται επιπλέον τα κριτήρια εκείνα με βάση τα οποία θα πρέπει να γίνεται η επιλογή του κατάλληλου εταίρου καθώς και οι μηχανισμοί για τη σωστή διακυβέρνηση μιας συμμαχίας. Εμβαθύνοντας σε επιμέρους στοιχεία της συμμαχίας, όπως είναι η κουλτούρα, η επικοινωνία και η συμπληρωματικές δεξιότητες καταλήγουμε στα χαρακτηριστικά που θα πρέπει να έχει μια επιτυχημένη στρατηγική συμμαχία. Κάνοντας επισκόπηση στη στρατηγική διεθνοποίησης που ακολούθησε η MAS A.E. αλλά και στα εφόδια που αποκόμισε μέσα από τη στρατηγική της συνεργασία με τη Woodward διαπιστώνουμε τον τρόπο με τον οποίο οι επιτυχημένες στρατηγικές συμμαχίες αλλάζουν και ενδυναμώνουν τις επιχειρήσεις. Για το σκοπό αυτό πραγματοποιήθηκαν συνεντεύξεις σε άτομα που κατέχουν «θέσεις – κλειδιά» στη δημιουργία και στη λειτουργία της στρατηγικής συμμαχίας και συμπληρώθηκαν ερωτηματολόγια ανοιχτού τύπου για τους υπεύθυνους των τμημάτων καθώς και για τους υπαλλήλους της εταιρίας.
