description: It is shown by microscopic calculations for trapped imbalanced Fermi superfluids that the gap function has always sign changes, i.e., the Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state like, up to a critical imbalance $P_c$, beyond which normal state becomes stable, at temperature T=0. A phase diagram is constructed in $T$ vs $P$, where the BCS state without sign change is stable only at $T\neq 0$. We reproduce the observed bimodality in the density profile to identify its origin and evaluate $P_c$ as functions of $T$ and the coupling strength. These dependencies match with the recent experiments.

description: Στα πλαίσια της παρούσας διπλωματικής εργασίας προτείνεται μια μέθοδος για τη συγκέντρωση των χαρακτηριστικών με σκοπό να ξεπεράσει προηγούμενους περιορισμούς. Παρουσιάζεται ένας αναδρομικός κβαντιστής ικανός να επεξεργαστεί επιτυχώς ακολουθιακά δεδομένα και να εξάγει μία συμπαγή αναπαράσταση, η οποία ενσωματώνει τη χρονική πληροφορία της εισόδου. Η προτεινόμενη μέθοδος έχει εμπνευστεί από το Bag-of-Features μοντέλο, αλλά σε αντίθεση με αυτό, ο αναδρομικός χαρακτήρας του κβαντιστή επιτρέπει την διατήρηση της χωρικής πληροφορίας των δεδομένων. Η απόδοση της μεθόδου μελετήθηκε μέσω μιας σειράς πειραμάτων και συγκρίθηκε με άλλες μεθόδους πάνω στα προβλήματα της αναγνώρισης δραστηριότητας σε βίντεο και της ταξινόμησης εικόνων. Για την πρώτη περίπτωση τα αποτελέσματα σε τρεις βάσεις δεδομένων επιβεβαίωσαν ότι η προτεινόμενη μέθοδος μπορεί να αναλύσει την χρονική πληροφορία του βίντεο και να αυξήσει την ακρίβεια του μοντέλου. Για το πρόβλημα της ταξινόμησης εικόνων τα αποτελέσματα σε τρεις βάσεις στατικών εικόνων κατέδειξαν ότι ο αναδρομικός χαρακτήρας του κβαντιστή μπορεί να αξιοποιηθεί ακόμη και στην περίπτωση επεξεργασίας μη ακολουθιακών δεδομένων, ώστε να διατηρηθεί η χωρική τους πληροφορία
description: In this thesis, a novel stateful recurrent pooling approach, that can overcome the aforementioned limitations, is proposed. The proposed method is inspired by the well-known Bag-of-Features (BoF) model, but employs a stateful trainable recurrent quantizer, instead of plain static quantization, allowing for efficiently processing sequential data and encoding both their temporal, as well as their spatial aspects. The effectiveness of the proposed model to enclose spatio-temporal information compared to other competitive methods is demonstrated in the tasks of activity recognition and image classification. For the first case, the results using three different datasets implied that the proposed method can effectively process sequential data and capture the temporal information. While results over three image datasets for the second case validated that the recurrent nature of the quantizer can be utilized to preserve the spatial information of non-sequential data

description: We measure the ages, stellar masses, and star formation histories of z~6 galaxies, observed within 1Gyr of the Big Bang. We use imaging from HST and Spitzer from the public "Great Observatories Origins Deep Survey", coupled with ground-based near-infrared imaging, to measure the spectral energy distributions from 0.8-5microns, spanning the rest-frame UV and optical. From our sample of ~50 i-drop Lyman-break star-forming galaxies in GOODS-South with z'(AB)<27mag, we focus on ~30 with reliable photometric or spectroscopic redshifts. Half of these are confused with foreground sources at Spitzer resolution, but from the 16 with clean photometry we find that a surprisingly large fraction (40%) have evidence for substantial Balmer-breaks. This indicates the presence of old underlying stellar populations that dominate the stellar masses. For these objects, we find ages of 200-700Myr, implying formation redshifts of 77 could have played a major role in reionizing the universe.

description: The objective of this research paper was to demonstrate how the Greek press dealt with the recent Qatargate scandal, which shook the Greek political scene as well as the European and international public sphere due to the involvement of current and former MEPs and people working in the European institutions. This thesis, through conducting a thematic content analysis, focused on the newspapers, Efimerida ton Syntakton, Avgi and Kathimerini, examining the way they approached the scandal and communicated it to the public opinion. The sample of the research consisted of articles published in the three newspapers mentioned above from December 2022 to February 2023.The articles were analysed based on thematic content analysis. The results of the research showed that the press in Greece handled the scandal with great maturity and professionalism, shaping to a significant extent the agenda of public opinion and providing it with the required information, thoroughly and in detail, regarding the developments of the events related to Qatargate. All three newspapers under consideration worked within an ethical journalistic framework and worked objectively and respectfully towards both the public and the parties involved, as the scandal is still ongoing.
Structural characterization of lipids using 193 nm ultraviolet photodissociation mass spectrometry

description: As their diversity of structures suggests, lipids have a wide range of functions from storing energy to participant signal transduction. Over the last decade, mass spectrometry has emerged as a powerful analytical tool for identification and quantitation of lipids. While tandem mass spectrometry affords a higher level of structural characterization than intact mass measurements alone, conventional ion activation methods often fail to elucidate subtle yet critical structural features. The research presented in this dissertation explores the utility of 193 nm ultraviolet photodissociation (UVPD), a fast and high-energy alternative ion activation method, for structural characterization of phosphatidylcholines and lipooligosaccharides. Phosphatidylcholines are the most abundant glycerophospholipid in mammalian cell membranes and therefore represent an important analytical target. Low-energy collision-based activation methods generate head group and acyl chain fragment ions that permit determination of the lipid class and acyl chain composition, respectively. Photodissociation at 193 nm UVPD similarly produced head group and acyl chain fragment ions, in addition to diagnostic pairs of fragment ions that afforded localization of double bonds within acyl chains. Implementation of UVPD in a shotgun lipidomic workflow enabled identification of double bond positional isomers in complex glycerophospholipid extracts that otherwise would have gone undetected with low-energy collision-based activation methods. Coupling of the UVPD method to a mass spectrometry imaging workflow further facilitated detection of double bond positional isomers in situ. Changes in the relative abundances of double bond positional isomers were correlated to specific tissue features. Lipooligosaccharides (LOS) are saccharolipids that are the main component of the outer membrane of Gram-negative bacteria. Determination of unknown lipooligosaccharides structures and modifications is crucial considering the relationship between LOS structures and the development of antibiotic resistance. A mass spectrometry method utilizing the MS [superscript n] capabilities of linear ion trap mass analyzer, 193 nm UVPD, and high resolution scanning in the Orbitrap mass analyzer facilitated detailed structural characterization of intact LOS structures in both shotgun and chromatographic workflows. The methods permitted both localization of non-stoichiometric modification and determination of unknown core oligosaccharide structures

description: The aim of the present thesis was the study of the way Greek press recorded Kemal Ataturk’s reforms in Turkey. In particular, we examined which reforms Greek press focused on and why, as well as how the political situation and the greek-turkish relations affected the recording of the kemalist reforms by the press of Greece. The newspapers that were reviewed in order to answer the aforementioned questions, were primarily the “Vradini” and complementarily the “Acropolis” and the “Ethnos”. The quantity and quality of the recording of the kemalist reforms by the newspapers at hand in combination with the historic facts of the period led to the extraction of the conclusions of the thesis

description: The invaded cluster approach is extended to 2D Potts model with annealed vacancies by using the random-cluster representation. Geometrical arguments are used to propose the algorithm which converges to the tricritical point in the two-dimensional parameter space spanned by temperature and the chemical potential of vacancies. The tricritical point is identified as a simultaneous onset of the percolation of a Fortuin-Kasteleyn cluster and of a percolation of "geometrical disorder cluster". The location of the tricritical point and the concentration of vacancies for q = 1, 2, 3 are found to be in good agreement with the best known results. Scaling properties of the percolating scaling cluster and related critical exponents are also presented.

description: The growing expanse of e-commerce and the widespread availability of online databases raise many fears regarding loss of privacy and many statistical challenges. Even with encryption and other nominal forms of protection for individual databases, we still need to protect against the violation of privacy through linkages across multiple databases. These issues parallel those that have arisen and received some attention in the context of homeland security. Following the events of September 11, 2001, there has been heightened attention in the United States and elsewhere to the use of multiple government and private databases for the identification of possible perpetrators of future attacks, as well as an unprecedented expansion of federal government data mining activities, many involving databases containing personal information. We present an overview of some proposals that have surfaced for the search of multiple databases which supposedly do not compromise possible pledges of confidentiality to the individuals whose data are included. We also explore their link to the related literature on privacy-preserving data mining. In particular, we focus on the matching problem across databases and the concept of ``selective revelation'' and their confidentiality implications.

description: The present thesis deals with issues, concerning detention warrants in the context of the concurrence of offences. Its aim is to point out the difficulties that arise from the application of article 288 of the Code of Criminal Procedure, not only in the case of ideal concurrence and serial crime, but also in the case of real concurrence. The first part of the thesis begins with a short description of the legal nature of detention and continues with an analysis of the conditions of the enforcement of detention. The second part, deals with the most important issue of the present thesis, which is the legal status before the addition of the second paragraph of the article 288 of the Code of Criminal Procedure, due to the Law 2408/1996, the problems that occurred and the solutions to them. Furthermore, the present legal status, the issues that this addition caused and the solutions that were given to them, both in theory and in case law, are also examined in this part

description: This thesis examines naval base expansion by the U.S. Navy during peace-time from 1898 to 1916 as the basis for considering important aspects of American naval policy and politics during a critical period of growth.  It delineates the base budgetary dynamics of the navy, therefore providing a more complete representation of the dynamics of supporting a fleet.  There are two related major arguments.  First, that the United States built a fleet without adequate provision for the bases to support operations.  And second, the naval spending was, largely driven by legislative political rather than strategic considerations.  Exposition of these propositions will include consideration of the problem of naval bases as affected by `pork-barrel politics, the manifestations of inter-service rivalry, and the lack of enforcement of a general naval policy.  In addition, this thesis will examine the place of base spending with respect to overall expenditure on the navy.

subject: FOS: Civil engineering

description: The thesis aims to challenge the current norm and policy of Singapore's subsidized housing, HDB, to create a type of housing that is more adaptable and responsible to current and future challenges. Through the exploration in progressive construction techniques and technology, HDB housing could function and perform sustainably for the community of HDB dwellers as well as for the environment. The affect of an increase in population count in Singapore results in a higher demand for HDB (government-subsidized housing). Along with housing shortage, Singapore is facing a water crisis. Efforts has been made to conserve, capture, and treat water for the population but Singapore still needs to import about 30% of their water from Malaysia. The research and exploration in this thesis aims to resolve some of the issue involving the limited land surface for storing and harvesting rainwater from the abundant rainfall, in order to meet the water requirement of the population in the near future.

description: This thesis explores the dialectical tensions, ironies, and myths of North Korea, with the hope of exposing fallacies and bringing awareness to the crisis of the oppressed citizens of this hermetic country.  There are discrepancies between the North Korea that most people know, and one that is lesser known, which contains the everyday stories of real people.  The goal is to design a cultural landscape containing the narratives of the persecuted in an effort to promote understanding about a country that is largely misinterpreted because of the images the Kim dictatorship and international media have planted in the minds of many people.  The architecture provides a ground for commentary on the truth and what can be done to change the current state of apathy, ignorance, and helplessness.  Acts of violation against humanity that continue in North Korea must be stopped.  The fact that the North and South must reunite to save the citizens of North Korea is a pressing issue that the South Koreans must genuinely want in order to create change.  Gathering information about Korea's history and attributes of the proposed site will reveal how time changes space, the way our memories and ideas are both temporal and timeless as they are exchanged.  When we become more aware of the issues at large, it will change our indifference and help us react to the stories that are told.

description: One central issue in the formal design and analysis of reactive systems is the notion of refinement that asks whether all behaviors of the implementation is allowed by the specification. The local interpretation of behavior leads to the notion of simulation. Alternating transition systems (ATSs) provide a general model for composite reactive systems, and the simulation relation for ATSs is known as alternating simulation. The simulation relation for fair transition systems is called fair simulation. In this work our main contributions are as follows: (1) We present an improved algorithm for fair simulation with Büchi fairness constraints; our algorithm requires O(n3 · m) time as compared to the previous known O(n6)-time algorithm, where n is the number of states and m is the number of transitions. (2) We present a game based algorithm for alternating simulation that requires O(m2)-time as compared to the previous known O((n · m)2)-time algorithm, where n is the number of states and m is the size of transition relation. (3) We present an iterative algorithm for alternating simulation that matches the time complexity of the game based algorithm, but is more space efficient than the game based algorithm.

description: Energy storage devices such as batteries are important elements in many electronic devices. Currently, researchers are seeking to create new electronic devices that are "soft", i.e., bendable and stretchable. However, the batteries that power such devices are still mostly hard structures. In the current thesis, we have attempted to develop a "soft" battery out of hydrogels. Specifically, we have made a soft version of the Daniell Cell, which is a classic electrochemical cell. Our design involves a hybrid gel composed of three distinct layers. The top and bottom layers are gels swollen with a zinc salt and a copper salt, respectively, while the middle layer is akin to a "salt bridge" between the two. The hybrid gel is made by a polymerization technique developed in our laboratory and it retains good mechanical integrity (i.e., the individual layers do not delaminate). Zinc and copper foils are then attached to the hydrogel, thus creating an overall battery, and its discharge performance is reported. One unique aspect of these gel batteries is that they can be dehydrated and stored in a dry form, whereupon they are no longer batteries. In this inactive state, the materials are safe and light to transport. Upon rehydration, the gels revert to being functional batteries. This concept could be useful for military or other applications where an emergency energy storage is needed.

description: We describe short-time kinetic and steady-state properties of the non--equilibrium phases, namely, solid, liquid and gas anisotropic phases in a driven Lennard-Jones fluid. This is a computationally-convenient two-dimensional model which exhibits a net current and striped structures at low temperature, thus resembling many situations in nature. We here focus on both critical behavior and details of the nucleation process. In spite of the anisotropy of the late--time spinodal decomposition process, earlier nucleation seems to proceed by Smoluchowski coagulation and Ostwald ripening, which are known to account for nucleation in equilibrium, isotropic lattice systems and actual fluids. On the other hand, a detailed analysis of the system critical behavior rises some intriguing questions on the role of symmetries; this concerns the computer and field-theoretical modeling of non-equilibrium fluids.

description: We consider the problem of inference in agraphical model with binary variables. While in theory it is arguably preferable to compute marginal probabilities, in practice researchers often use MAP inference due to the availability of efficient discrete optimization algorithms. We bridge the gap between the two approaches by introducing the Discrete Marginals technique in which approximate marginals are obtained by minimizing an objective function with unary and pair-wise terms over a discretized domain. This allows the use of techniques originally devel-oped for MAP-MRF inference and learning. We explore two ways to set up the objective function - by discretizing the Bethe free energy and by learning it from training data. Experimental results show that for certain types of graphs a learned function can out-perform the Bethe approximation. We also establish a link between the Bethe free energy and submodular functions.

The origins and uses of love in the cinema of Francois Truffaut
Creators: name: Harris, Mark Robert
Publisher: name: University of British Columbia
Year: 2009

description: The Origins and Uses of Love in the Cinema of Francois Truffaut attempts to explain how the Nouvelle Vague filmmaker's passions and enthusiasms created both the substance and aesthetic of his work. For the sake of concision, this study has been restricted primarily to the analysis of eight key films in the director's work. These seven features and one short have been further sub-divided into three "blocs": Les 400 coups, Antoine et Colette, Baisers voles. Domicile conjugale, and L'Amour en fuite making up the set centred on the adventures of Antoine Doinel; Jules et Jim and Les_ Deux anglaises et le continent constituting the diptych inspired by the novels of Henri-Pierre Roche; and Tirez sur le pianiste, the sole monadal entry, representing Truffaut's attraction to Hollywood genre cinema. Each of the director's four principal passions are granted a self-explicating chapter: Love of Children, Love of Film, Love of Literature, and Love of Love. In the first of these thematic chapters, it is pointed out that Truffaut's love of children was counterbalanced by an equally profound hatred for the objective conditions of childhood. Love of Film encompasses film criticism as well as film-making; it shows how Truffaut's formative viewing experiences subsequently influenced his choice of subject matter. Love of .literature places special emphasis on the works of Honore de Balzac and Henri-Pierre Roche, The Antoine Doinel films, it is argued, are essentially a mini-Comedie humaine. Love of Love encompasses both romance and friendship. How Truffaut could glory in the pleasures of heterosexual love without really believing in its permanence proves pivotal in this chapter. How all these "loves" were bounded by the director's love/hate relationship to time is discussed in the thesis conclusion.

description: We investigated the elastic scattering problem with deformed Heisenberg algebra leading to the existence of a minimal length. The continuity equations for the moving particle in deformed space were constructed. We obtained the Green's function for a free particle, scattering amplitude and cross-section in deformed space. We also calculated the scattering amplitudes and differential cross-sections for the Yukawa and the Coulomb potentials in the Born approximation.

description: In the last decades, extreme classification has become an essential topic for deep learning. It has achieved great success in many areas, especially in computer vision and natural language processing (NLP). However, it is very challenging to train a deep model with millions of classes due to the memory and computation explosion in the last output layer. In this paper, we propose a large-scale training system to address these challenges. First, we build a hybrid parallel training framework to make the training process feasible. Second, we propose a novel softmax variation named KNN softmax, which reduces both the GPU memory consumption and computation costs and improves the throughput of training. Then, to eliminate the communication overhead, we propose a new overlapping pipeline and a gradient sparsification method. Furthermore, we design a fast continuous convergence strategy to reduce total training iterations by adaptively adjusting learning rate and updating model parameters. With the help of all the proposed methods, we gain 3.9$\times$ throughput of our training system and reduce almost 60\% of training iterations. The experimental results show that using an in-house 256 GPUs cluster, we could train a classifier of 100 million classes on Alibaba Retail Product Dataset in about five days while achieving a comparable accuracy with the naive softmax training process.

Synchrotron Outbursts in Galactic and Extra-galactic Jets, Any Difference?

description: We discuss differences and similarities between jets powered by super-massive black holes in quasars and by stellar-mass black holes in microquasars. The comparison is based on multi-wavelength radio-to-infrared observations of the two active galactic nuclei 3C 273 and 3C 279, as well as the two galactic binaries GRS 1915+105 and Cyg X-3. The physical properties of the jet are derived by fitting the parameters of a shock-in-jet model simultaneously to all available observations. We show that the variable jet emission of galactic sources is, at least during some epochs, very similar to that of extra-galactic jets. As for quasars, their observed variability pattern can be well reproduced by the emission of a series of self-similar shock waves propagating down the jet and producing synchrotron outbursts. This suggests that the physical properties of relativistic jets is independent of the mass of the black hole.

Enzyme immobilization using the cellulose-binding domain of the Cellulomonas Fimi exoglucanase
Creators: name: Ong, Edgar
Publisher: name: University of British Columbia
Year: 2008

description: A new strategy employing molecular genetic techniques to produce fusion polypeptides was used for enzyme immobilization. The cellulose-binding domain (CBD) of the Cellulomonas fimi exoglucanase (Cex) was used as an affinity "tag" by fusing the sequence encoding CBDcex to the 3'-ends of the genes encoding two β-glucosidases, Abg and Cbg, from a mesophilic Agrobacterium sp. and a thermophilic bacterium, Caldocellum saccharolyticum, respectively. The resulting fusion polypeptides, Abg-CBDcex and Cbg-CBDcex, were purified to >95% homogeneity in a single step by affinity chromatography on cellulose using water as the desorbing agent. Protein recovery varied from 58-70%. The matrix, pH and temperature affected the reversibility of binding. These parameters can be selected to facilitate either purification or stable immobilization of the polypeptide. Fusion of the affinity "tag" appeared not to affect the conformation of the fusion partners significantly, since their specific activities were not altered appreciably. Kinetic analyses revealed that the increase in apparent Km of the immobilized Abg-CBDcex was not directly related to the fusion, but rather, to external mass transfer resistance. The percentage of activity retained by the immobilized enzyme was inversely related to the amount of fusion polypeptide adsorbed to cellulose. This was affected by the presence of an extra 57 amino acid residues between the fusion partners. Abg-CBDcex was stably adsorbed to cellulose between 4° to 50°; pH 3 to 8.5; and in the presence of up to 1 M NaCl. The immobilized Abg-CBDcex column exhibited long-term operational stability (at least 15 days at 37°) and gave 50-70% substrate conversion at the flow rates employed. At 50° Abg-CBDcex lost activity but remained bound to cellulose. Immobilized Cbg-CBDcex was stable at 70° for at least 3 days with no apparent desorption of fusion polypeptide from the column. The use of a more crystalline cellulosic support improved the stability of binding of both fusion polypeptides. A plasmid that expressed the gene encoding CBDcex alone was also constructed to facilitate biochemical analysis of the binding mechanism. CBDcex was purified from culture supernatant to > 98% homogeneity in a single step by batch affinity chromatography on cellulose. Unlike the fusion polypeptides, it was not desorbed with water. The presence of xylan in the CBDcex preparation affected its susceptibility to cleavage by pepsin. CBDcex bound stably to both amorphous and crystalline cellulose, and under a wide range of temperatures, pHs and detergent concentrations.

description: Mild Traumatic Brain Injury (MTBI) is one of the most common

neurological disorders. A subset of patients develop persistent

cognitive deficits. A number of the brain studies have been conducted

to discover the abnormalities and disruptions in the brain functional

networks using similar methods to those employed in more severe brain

disorders such as Alzheimer's or Schizophrenia. Static functional

network analysis using resting state brain fMRI images has shown some

promising results in identifying characteristics of MTBI.  However,

recent development in the dynamics of functional networks have been

able to reveal insightful information about anomalies in brain

activities that have not been observed when using traditional static

analysis.  Our work focuses on both static and dynamic functional

analysis of the brain. Our overall analysis pipeline is data-driven

using a dataset of 47 MTBI subjects and a demographically matching

healthy control group size of 30. The data-driven approach

proactively removes noise, focuses on the entire brain functional

networks and performs advanced independent component analysis,

followed by statistical tests to characterize the functional networks

of MTBI patients.  A key distinction of our research is the finer

labeling of MTBI subject according to their long term 6 months

recovery status. Our results suggest that those MTBI subject who

suffer prolonged recovery exhibit disturbed functional networks, and

slowed dynamism in functional connectivity than those of the healthy

control or those MTBI participants who recovered quickly. A number of

useful network measurements have been found to capture the states and

changes of the brain functional networks for healthy and different

types of MTBI subjects in their resting state.  We believe that our

findings can shed more light into the impact of MTBI on the

effectiveness of several functional networks and can contribute to

helping clinicians make more informed decisions to aid in the recovery

of MTBI patients.
Accretion rate and the occurrence of multi-peaked X-ray bursts

description: Most Type I X-ray bursts from accreting neutron stars have a lightcurve with a single peak, but there is a rare population of faint bursts that are double or even triple peaked. Suggested mechanisms include polar ignition with equatorial stalling, or multi-step energy release; the latter being caused by hydrodynamic instabilities or waiting points in the nuclear reaction sequence. We present an analysis of the accretion rate dependence of the multi-peak bursts, and discuss the consequences for the various models. The observations pose particular challenges for the polar ignition mechanism given current models of ignition latitude dependence.

description: Using the mollifier method, we show that for a positive proportion of holomorphic Hecke eigenforms of level one and weight bounded by a large enough constant, the associated symmetric square $L$-function does not vanish at the central point of its critical strip. We note that our proportion is the same as that found by other authors for other families of $L$-functions also having symplectic symmetry type.

description: In the presence of weak time harmonic electromagnetic fields, Superconducting Quantum Interference Filters (SQIFs) show the typical behavior of non linear mixers. The SQIFs are manufactured from high-T_c grain boundary Josephson junctions and operated in active microcooler. The dependence of dc voltage output V_dc vs. static external magnetic field B is non-periodic and consists of a well pronounced unique dip at zero field, with marginal side modulations at higher fields. We have successfully exploited the parabolic shape of the voltage dip around B=0 to mix quadratically two external time harmonic rf-signals, at frequencies f_1 and f_2 below the Josephson frequency f_J, and detect the corresponding mixing signal at f_1-f_2. When the mixing takes place on the SQIF current-voltage characteristics the component at 2f_2 - f_1 is present. The experiments suggest potential applications of a SQIF as a non-linear mixing device, capable to operate at frequencies from dc to few GHz with a large dynamic range.

description: We present a new multi-wavelength study of supernova remnant (SNR) B0513-692 in the Large Magellanic Cloud (LMC). The remnant also has a strong, superposed, essentially unresolved, but unrelated radio source at its north-western edge, J051324-691049. This is identified as a likely compact HII region based on related optical imaging and spectroscopy. We use the Australia Telescope Compact Array (ATCA) at 4790 and 8640 MHz to determine the large scale morphology, spectral index and polarization characteristics of B0513-692 for the first time. We detect a strongly polarized region (49%) in the remnant's southern edge. Interestingly we also detect a small (~40 arcsec) moderately bright, but distinct optical, circular shell in our Halpha imagery which is adjacent to the compact HII region and just within the borders of the NE edge of B0513-692. We suggest this is a separate new SNR candidate based on its apparently distinct character in terms of optical morphology in 3 imaged emission lines and indicative SNR optical spectroscopy (including enhanced optical [SII] emission relative to Halpha).
