description: We study the properties of a two-dimensional non-relativistic electron gas (TDEG) constrained on wires along a Möbius strip. We considered wires around the strip and along the transverse direction, across the width of the strip. For each direction, we investigate how the curvature modifies the electronic states and their corresponding energy spectrum. At the center of the strip, the wires around the surface form quantum rings whose spectrum depends on the strip radius $a$. For wires at the edge of the strip, the inner edge turns into the outer edge. Accordingly, the curvature yields localized states in the middle of the wire. Along the strip width, the effective potential exhibits a parity symmetry breaking leading to the localization of the bound state on one side of the strip.

description: We present a CO(2-1) mosaic map of the spiral galaxy NGC 6946 by combining data from the Submillimeter Array and the IRAM 30 m telescope. We identify 390 giant molecular clouds (GMCs) from the nucleus to 4.5 kpc in the disk. GMCs in the inner 1 kpc are generally more luminous and turbulent, some of which have luminosities >10^6 K km/s pc^2 and velocity dispersions >10 km/s. Large-scale bar-driven dynamics likely regulate GMC properties in the nuclear region. Similar to the Milky Way and other disk galaxies, GMC mass function of NGC 6946 has a shallower slope (index>-2) in the inner region, and a steeper slope (index

Toward 'sense of place': an ethnographic exploration of islandness
Creators: name: Craig, Sandra
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This work combines ethnographic research with concepts drawn from island studies, and phenomenology of place, to investigate local constructions of island identity on North Stradbroke Island (Minjerribah) Queensland, Australia. The research project explores embodied senses of place, lived experiences and perceptions of the environment, in the everyday lives and discourses of diverse island residents. Fieldwork was undertaken on North Stradbroke Island throughout 2014. The ethnographic material is analysed using approaches to islandness drawn from the evolving interdisciplinary field of island studies. Island studies seeks to explore the distinct features of island lives and cultures, studying islands ‘on their own terms’ (McCall 1994). The extreme diversity of physical islands, and the complex elaboration of island metaphors present conceptual obstacles to a coherent theorisation of islandness. Following Hay (2006) this thesis posits phenomenology of place as a productive approach to addressing the ‘radical particularity’ inherent in the vast diversity among islands. Drawing on concepts of place from philosophy, human geography and existential anthropology, sense of place opens up the everyday lived experience of embodied island existence, and identity. Phenomenology and the ‘lifeworld’ concept can address socially constructed intersubjective, and material physical dimensions of bodily entanglements in divergent local island landscapes.
Biologically-inspired characterization of sparseness in natural images

Subjects: subject: Neurons and Cognition (q-bio.NC)
subject: FOS: Biological sciences

description: Natural images follow statistics inherited by the structure of our physical (visual) environment. In particular, a prominent facet of this structure is that images can be described by a relatively sparse number of features. We designed a sparse coding algorithm biologically-inspired by the architecture of the primary visual cortex. We show here that coefficients of this representation exhibit a heavy-tailed distribution. For each image, the parameters of this distribution characterize sparseness and vary from image to image. To investigate the role of this sparseness, we designed a new class of random textured stimuli with a controlled sparseness value inspired by our measurements on natural images. Then, we provide with a method to synthesize random textures images with a given statistics for sparseness that matches that of some given class of natural images and provide perspectives for their use in neurophysiology.

description: We propose the use of a combination of ultrasonic and magnetic fields in conductive media for the creation of RF electrical current via the Lorentz force, in order to achieve current generation with extreme sub-wavelength resolution at large depth. We demonstrate the modeling, generation, and measurement of Lorentz current in conductive solution, and show that this current can be localized at a distance of 13 $cm$ from the ultrasonic source to a region about three orders of magnitude smaller than the corresponding wavelength of electromagnetic waves at the same operation frequency. Our results exhibit greater depth, tighter localization, and closer agreement with prediction than previous work on the measurement of Lorentz current in a solution of homogeneous conductivity. The proposed method of RF current excitation overcomes the trade-off between focusing and propagation that is fundamental in the use of RF electromagnetic excitation alone, and has the potential to improve localization and depth of operation for RF current-based biomedical applications.

Difficulty of distinguishing product states locally

name: Barnett, Stephen M
Publisher: name: arXiv
Year: 2017
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Non-locality without entanglement is a rather counter-intuitive phenomenon in which information may be encoded entirely in product (unentangled) states of composite quantum systems in such a way that local measurement of the subsystems is not enough for optimal decoding. For simple examples of pure product states, the gap in performance is known to be rather small when arbitrary local strategies are allowed. Here we restrict to local strategies readily achievable with current technology; those requiring neither a quantum memory nor joint operations. We show that, even for measurements on pure product states there can be a large gap between such strategies and theoretically optimal performance. Thus even in the absence of entanglement physically realizable local strategies can be far from optimal for extracting quantum information.

description: This letter is focused on the design and analysis of computational wideband time-reversal imaging algorithms, designed to be adaptive with respect to the noise levels pertaining to the frequencies being employed for scene probing. These algorithms are based on the concept of cell-by-cell processing and are obtained as theoretically-founded decision statistics for testing the hypothesis of single-scatterer presence (absence) at a specific location. These statistics are also validated in comparison with the maximal invariant statistic for the proposed problem.

description: It has been argued that the 0.7 anomaly in quantum point contacts (QPCs) is due to an enhanced density of states at the top of the QPC-barrier (van Hove ridge), which strongly enhances the effects of interactions. Here, we analyze their effect on dynamical quantities. We find that they pin the van Hove ridge to the chemical potential when the QPC is subopen; cause a temperature dependence for the linear conductance that qualitatively agrees with experiment; strongly enhance the magnitude of the dynamical spin susceptibility; and significantly lengthen the QPC traversal time. We conclude that electrons traverse the QPC via a slowly fluctuating spin structure of finite spatial extent.
A Dual-branch Self-supervised Representation Learning Framework for Tumour Segmentation in Whole Slide Images

description: Supervised deep learning methods have achieved considerable success in medical image analysis, owing to the availability of large-scale and well-annotated datasets. However, creating such datasets for whole slide images (WSIs) in histopathology is a challenging task due to their gigapixel size. In recent years, self-supervised learning (SSL) has emerged as an alternative solution to reduce the annotation overheads in WSIs, as it does not require labels for training. These SSL approaches, however, are not designed for handling multi-resolution WSIs, which limits their performance in learning discriminative image features. In this paper, we propose a Dual-branch SSL Framework for WSI tumour segmentation (DSF-WSI) that can effectively learn image features from multi-resolution WSIs. Our DSF-WSI connected two branches and jointly learnt low and high resolution WSIs in a self-supervised manner. Moreover, we introduced a novel Context-Target Fusion Module (CTFM) and a masked jigsaw pretext task to align the learnt multi-resolution features. Furthermore, we designed a Dense SimSiam Learning (DSL) strategy to maximise the similarity of different views of WSIs, enabling the learnt representations to be more efficient and discriminative. We evaluated our method using two public datasets on breast and liver cancer segmentation tasks. The experiment results demonstrated that our DSF-WSI can effectively extract robust and efficient representations, which we validated through subsequent fine-tuning and semi-supervised settings. Our proposed method achieved better accuracy than other state-of-the-art approaches. Code is available at https://github.com/Dylan-H-Wang/dsf-wsi.
What makes us responsible: Fischer and Ravizza on implicit attitudes
Creators: name: Ledger, Michael

Subjects: Other education not elsewhere classified

description: Implicit attitudes are a mental construct which can affect our behaviours. However, the influence of these attitudes can sometimes lead to their being manifested in potentially prejudicial or discriminatory behaviours. Because of the potentially harmful effects of these behaviours, it is important that theories of moral responsibility be able to properly regard behaviours which manifest our implicit attitudes. However, there is considerable divergence in opinions in the literature surrounding the nature of implicit attitudes and the effects they have on behaviour. Therefore, determining the extent to which we may be held morally responsible for our actions manifesting our implicit attitudes can prove difficult. The theory of moral responsibility put forward by Fisher and Ravizza (1998) presents a criterion for responsibility which I argue is capable of sufficiently responding to the challenges posed by implicit attitudes. The following project is therefore an examination of the Fischer and Ravizza theory, and its notion of a reasons-responsive deliberative mechanism. This project is also an inquiry into the nature of implicit attitudes and the role they play in this deliberative mechanism. Thus I ask the question, 'according to a Fischer and Revizza theory of responsibility, to what extent may we be held morally reasponsible for our actions manifesting our implicit attitudes'?

description: Ayant été plusieurs fois confrontés au conseil de classe durant nos stages, nous nous sommes interrogés sur son fonctionnement et ses finalités. Notre objectif durant ce travail a été d’observer, d’analyser et de commenter les différents conseils de classe réalisés par des élèves au sein de nos deux classes de stage. Cette étude a été faite avec deux classes de 6P dans le canton de Vaud. Les recherches menées nous ont permis de déterminer comment l’autonomie lors d’un conseil de classe pouvait ou non être développée. Pour ce faire, nous nous sommes appuyés sur le cadre théorique composé de divers concepts, tels que l’autonomie, la communication, les postures de l’enseignant, les règles ou encore le rituel. Afin de la mener à bien, nous avons utilisé une méthode de recherche de type inductive dans le cadre d’une analyse qualitative basée sur la Grounded Theory. Celle-ci s’est appuyée sur l’observation de données lors des focus groups, et l’interprétation de ces dernières a posteriori. Nous avons donc mis en place un espace de parole qui nous semblait idéal pour développer l’autogestion de la prise de parole, de la communication et de la prise de décision des élèves. Nous avons ensuite observé l’impact de ce dispositif au travers des retranscriptions qui ont été effectuées à partir des extraits de vidéos enregistrées lors des conseils. Ce dispositif nous a permis d’observer que l’instauration d’un conseil ritualisé et modélisé par l’enseignant permet aux élèves de devenir plus autonomes.

description: The introduction of the National Quality Standard (NQS) (ACECQA, 2011b) invites an investigation into how this major policy reform is being communicated and what impact it has among staff working in early childhood (EC) centres. The aim of this research study was to explore how relationships among EC educators influenced the organisational culture of EC centres, and how NQS was being communicated amongst educators. Data was collected through a questionnaire and semi-structured individual interviews with the directors/educational leaders, teachers and assistants from three community-based long day care centres in the Sydney metropolitan area, as well as an interview with the Director of the auspicing agency. Information available on public access through the website of the auspicing agency, and other related documents available to parents through their centres were also analysed to gain further insights on the nature of the organisational cultures of the participating centres. Thematic analysis of data from a social systems perspective identified emergent trends and issues of relevance to quality provisioning of EC programs. Findings suggest that the leadership of the centre directors and the Head Office of the auspicing agency, and a notion of interdependence between staff, played a key role in developing the organisational cultures of the centres. A democratic style of leadership was identified through intentional communication strategies which provided a sense of belonging and attachment to the settings, and collaborative reflection on practice provided a foundation for the implementation of NQS. Insights gained from this research can be used to inform training provisions for EC staff, specifically in support of the implementation of the national quality assessment and rating requirements.

description: We study the time evolution of a single qubit in contact with a bath, within the framework of projection operator methods. Employing the so-called modified Redfield theory which also treats energy conserving interactions non-perturbatively, we are able to study the regime beyond the scope of the ordinary approach. Reduced equations of motion for the qubit are derived in a idealistic system where both the bath and system-bath interactions are modeled by Gaussian distributed random matrices. In the strong decoherence regime, a simple relation between the bath correlation function and the decoherence process induced by the energy conserving interaction is found. It implies that energy conserving interactions slow down the relaxation process, which leads to a zeno freezing if they are sufficiently strong. Furthermore, our results are also confirmed in numerical simulations.

description: The ferroelectric material usually exhibits temperature dependent spontaneous polarization, known as pyroelectricity, which can be used to directly convert thermal energy to electricity from ambient low-grade waste heat. When utilizing the structural phase transformations of the material, the conversion capability can be magnified, consequently the device performance can be strongly boosted by orders of magnitude. However, common ferroelectric oxides suffer the mechanical fatigue and functional degradation over cyclic phase transformations, hindering widespread applications of the energy conversion device. In this paper, we investigate the mechanical and functional reversibility of the material by lattice tuning and grain coarsening. We discover the lead-free compound Ba(Ce$_{0.005}$Zr$_{0.005}$)Ti$_{0.99}$O3-0.10(Ba$_{0.7}$Ca$_{0.3}$)TiO$_3$ (BCZT-0.10BCT) satisfying the compatibility condition among all present phases by its lattice parameters, making the phase transformations highly reversible. We demonstrated that the energy conversion device with the equiaxial coarse grains exhibits exceptional fatigue-resistance, with stable pyroelectric current output at 4$μ$A/cm$^2$ over 3,000 energy conversion cycles. Our work opens a new way to fabricate high-performance material that advances the pyroelectric energy conversion for practical application in engineering.

description: The η Carinae binary system hosts the most massive stars with the highest known mass-loss rate. Its dense wind encounters the faster wind expelled by the companion, dissipating mechanical energy in the shock, accelerating particles up to relativistic energies and producing high-energy (HE) γ-rays. We used the first 7-year data of the Fermi LAT which span two passages of η Carinae at periastron. We extracted low and HE light curves and spectra in different orbital phase bins using the new PASS8 pipeline. We used particle acceleration in hydrodynamic simulations of the system in a multi-cell geometry and compared the prediction with the observations. The γ-ray emission location is compatible with η Carinae. Two emission components are distinguished. The low-energy (LE) one cuts off below 10 GeV and its flux, modulated by the orbital motion, varies by a factor < 2. Short-term variability occurs at periastron. The HE component flux varies by a factor 3-4 but differently during the two periastrons. The variabilities observed at LE and HE during the first half of the observations, match the prediction of the simulation, assuming a surface magnetic field of 500 G. The HE component and the thermal X-ray emission were weaker than expected around the second periastron suggesting a modification of the wind density in the inner wind collision region (WCR). Diffuse shock acceleration in the WCR provides a convincing match to the observations and new diagnostic tools to probe the geometry and energetics of the system. Further observations are required to explain the periastron-to-periastron HE variability and to associate it firmly with hadronic origin. η Carinae is a pevatron at periastron. Its $ν$ flux can be detected by IceCube after many years of observations. Orbital modulations of the HE component can be distinguished from those of photo absorption by CTA.

description: We present a state-of-the-art prediction for cross sections of neutrino deep inelastic scattering (DIS) from nucleon at high neutrino energies, $E_ν$, from 100 GeV to 1000 EeV ($10^{12}$ GeV). Our calculations are based on the latest CT18 NNLO parton distribution functions (PDFs) and their associated uncertainties. In order to make predictions for the highest energies, we extrapolate the PDFs to small $x$ according to several procedures and assumptions, thus affecting the uncertainties at ultra-high $E_ν$; we quantify the uncertainties corresponding to these choices. Similarly, we quantify the uncertainties introduced by the nuclear corrections which are required to evaluate neutrino-nuclear cross sections for neutrino telescopes. These results can be applied to currently-running astrophysical neutrino observatories, such as IceCube and KM3NeT, as well as various future experiments which have been proposed.

We examine the relation for solutions involving $X^0$ variables. As a result, we obtain that the relation may not hold for such solutions. Namely, there is a possibility that the energy is not proportional to the Ellwood invariant.

From the Rebecca riots to the Manic Street Preachers: Welsh cross-dressing as an act of political defiance
Creators: name: McIntyre, Jessica
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This thesis aims to explore representations of political cross-dressing in Welsh literature, with a focus on the Rebecca Riots of the 1830s. This research draw mainly upon primary texts by Amy Dillwyn, Dylan Thomas and Manic Street Preachers to explore themes of nationality, class, rebellion and gender in Welsh culture. These diverse texts and the thematic connections between them are, thus far, largely unexplored areas of literary studies. The goal is to show that there is evidence to support a complex critical reading of these textual constructions which goes beyond regarding them simply as literary curiosities. In particular, this thesis will demonstrate that literary representations of the male cross-dressing Rebecca Rioters provide insight into a unique, and largely unacknowledged, aspect of Welsh culture that questions, destabilizes and subverts gender identity. I intend to show that these themes continue to be represented and explored in Welsh literature, and that this is indicative of a different cultural attitude to gender and political protest than is found through the rest of Britain. by demonstrating that the influence of the Riots is ongoing in Welsh literature, this research highlights the importance of the Rebeccaites in shaping modern Welsh culture.

description: We study non-Markovian effects present in a driven qubit coupled to a finite environment using a recently proposed model developed in the context of calorimetric measurements of open quantum systems. To quantify the degree of non-Markovianity we use the Breuer-Laine-Piilo (BLP) measure [Breuer \textit{et al.}, Phys. Rev. Lett. \textbf{103}, 210401 (2009)]. We show that information backflow only occurs in the case of driving in which case we investigate the dependence of memory effects on the environment size, driving amplitude and coupling to the environment. We show that the degree of non-Markovianity strongly depends on the ratio between the driving amplitude and the coupling strength. We also show that the degree of non-Markovianity does not decrease monotonically as a function of the environment size.

description: We introduce a method for inferring an explicit PDE from a data sample generated by previously unseen dynamics, based on a learned context. The training phase integrates knowledge of the form of the equation with a differential scheme, while the inference phase yields a PDE that fits the data sample and enables both signal prediction and data explanation. We include results of extensive experimentation, comparing our method to SOTA approaches, together with ablation studies that examine different flavors of our solution.
Bioinformatics analysis of proteins and proteomes

description: The advancement of next-generation proteomics methodologies has led to an explosion in proteomics data. However, the analysis and interpretation of this data remains a challenge, as several proteins remain unannotated and uncharacterised for many organisms. Despite the presence of the large volume of mass spectrometry (MS) data in various datasets, over 10% human proteins are still considered 'missing'. Bioinformatics techniques can be used to provide comprehensive annotations for entire proteomes to provide valuable information regarding putative functions of proteins that can be validated and or supplemented with experimental data. The aims of this thesis are to tackle some of these challenges, firstly to develop a generic in silico bioinformatics pipeline to identify homologues and map putative functional signatures, gene ontology terms and biochemical pathways of novel organisms, or "missing'' proteins. This pipeline was used to identify homologues for 2,587 proteins and functional annotation for 2,486 proteins from black Périgord truffle (Tuber melanosporum Vittad), followed by MS-based shotgun proteomics to validate 836 proteins. The same pipeline was then used to annotate the human "missing" protein sequences on each human chromosome available through the ProtAnnotator web portal, with homologues from the mammalian kingdom for 2538 (66.2%, based on September 2013 data). ProtAnnotator also functionally annotated 1945 (50.8%) "missing" human proteins. ProtAnnotator 2.0 automated the process and provides an update to the annotation of the truffle proteome. The lack of coherency between the proteomics data submitted to various databases, processed by different search engines has limited their integration in the quest for uncovering human "missing" proteins. To this end, a scheme was worked out for comparing proteomics data from different sources, looking at proteotypicity and search engine scores, with guidelines on spectral quality analysis as well. Finally, ProtAnnotator and the proteomics data integration strategy above were integrated, to create a novel integrated web platform (MissingProteinPedia) to define, collate and make serviceable all available data (including single proteotypic MS spectra) from various databases and web platforms for human "missing" proteins. The MissingProteinPedia (MPP) platform comprises a freely available web interface for datamining, collaboration and validation of MS and publication data. MPP permits protein-level identification of proteins that have very short tryptic peptides, such as interleukin-9, proteins traditionally known but without proteomic or antibody data as well as those that are carefully identified by our integrated computational workflow followed by expert spectral analysis.The tools developed in this thesis provide data integration to accelerate the annotation of novel proteomes and the discovery of human missing proteins.

description: This paper provides a brief overview of dynamo scaling relationships for the degree of equipartition between magnetic and kinetic energies. Three basic approaches are adopted to explore these scaling relationships, with a first look at two simple models: one assuming magnetostrophy and another that includes the effects of inertia. Next, a third scaling relationship is derived that utilizes the assumptions that the dynamo possesses two integral spatial scales and that it is driven by the balance of buoyancy work and ohmic dissipation as studied in Davidson 2013. The results of which are then compared to a suite of convective dynamo simulations that possess a fully convective domain with a weak density stratification and that captured the behavior of the resulting dynamo for a range of convective Rossby numbers (Augustson et al. 2016).

A General Overview on Hybrid and Electric Vehicles
Creators: name: Melo, Pedro Miguel Azevedo De Sousa
Publisher: name: Neutro à Terra
Year: 2013

description: The economical and environment impacts of fossil energies increased the interest for hybrid, battery and fuel-cell electric vehicles. Several demanding engineering challenges must be faced, motivated by different physical domains integration. This paper aims to present an overview on hybrid (HEV) and electric vehicles (EV) basic structures and features. In addition, it will try to point out some of the most relevant challenges to overcome for HEV and EV may be a solid option for the mobility issue. New developments in energy storage devices and energy management systems (EMS) are crucial to achieve this goal.

description: Classical methods for acoustic scene mapping require the estimation of the time difference of arrival (TDOA) between microphones. Unfortunately, TDOA estimation is very sensitive to reverberation and additive noise. We introduce an unsupervised data-driven approach that exploits the natural structure of the data. Toward this goal, we adapt the recently proposed local conformal autoencoder (LOCA) – an offline deep learning scheme for extracting standardized data coordinates from measurements. Our experimental setup includes a microphone array that measures the transmitted sound source, whose position is unknown, at multiple locations across the acoustic enclosure. We demonstrate that our proposed scheme learns an isometric representation of the microphones’ spatial locations and can perform extrapolation over new and unvisited regions. The performance of our method is evaluated using a series of realistic simulations and compared with a classical approach and other dimensionality reduction schemes. We further assess reverberation’s influence on our framework’s results and show that it demonstrates considerable robustness.

description: Segundo as previsões da Entidade Reguladora dos Serviços Energéticos (ERSE), o défice tarifário deverá atingir em finais do 2013 um valor acumulado de 3,7 mil milhões de Euros. Na comunicação social, o défice tarifário (DT) é considerado como mais uma “renda” a alguns grupos de interesse. Na realidade o DT é justificado por uma acumulação sucessiva de diversos tipos de sobrecustos do sistema elétrico que não foi considerada nas tarifas e preços da eletricidade nos anos anteriores aos respetivos consumidores elétricos.

description: To accomplish secure group communication, it is essential to share a unique cryptographic key among group members. The underlying challenges to group key agreement are scalability, efficiency, and security. In a dynamic group environment, the rekeying process is more frequent; therefore, it is more crucial to design an efficient group key agreement protocol. Moreover, with the emergence of various group-based services, it is becoming common for several multicast groups to coexist in the same network. These multicast groups may have several shared users; a join or leave request by a single user can trigger regeneration of multiple group keys. Under the given circumstances the rekeying process becomes a challenging task. In this work, we propose a novel methodology for group key agreement which exploits the state vectors of group members. The state vector is a set of randomly generated nonce instances which determine the logical link between group members and which empowers the group member to generate multiple cryptographic keys independently. Using local knowledge of a secret nonce, each member can generate and share a large number of secure keys, indicating that SGRS inherently provides a considerable amount of secure subgroup multicast communication using subgroup multicasting keys derived from local state vectors. The resulting protocol is secure and efficient in terms of both communication and computation.

description: A produção de energia eólica e essencial para o cumprimento dos objetivos europeus, no âmbito das energias renováveis. De acordo com as previsões da União Europeia (UE), a produção hidroelétrica ira manter a sua posição dominante como fonte de energia renovável para a produção de energia elétrica. No entanto, o uso da energia eólica ira continuar a expandir e, em 2020 a capacidade eólica instalada devera superar o setor hidroelétrico.

description: Image-level weakly-supervised semantic segmentation (WSSS) reduces the usually vast data annotation cost by surrogate segmentation masks during training. The typical approach involves training an image classification network using global average pooling (GAP) on convolutional feature maps. This enables the estimation of object locations based on class activation maps (CAMs), which identify the importance of image regions. The CAMs are then used to generate pseudo-labels, in the form of segmentation masks, to supervise a segmentation model in the absence of pixel-level ground truth. Our work is based on two techniques for improving CAMs; importance sampling, which is a substitute for GAP, and the feature similarity loss, which utilizes a heuristic that object contours almost always align with color edges in images. However, both are based on the multinomial posterior with softmax, and implicitly assume that classes are mutually exclusive, which turns out suboptimal in our experiments. Thus, we reformulate both techniques based on binomial posteriors of multiple independent binary problems. This has two benefits; their performance is improved and they become more general, resulting in an add-on method that can boost virtually any WSSS method. This is demonstrated on a wide variety of baselines on the PASCAL VOC dataset, improving the region similarity and contour quality of all implemented state-of-the-art methods. Experiments on the MS COCO dataset further show that our proposed add-on is well-suited for large-scale settings. Our code implementation is available at https://github.com/arvijj/hfpl.

description: Differential geometric approaches to the analysis and processing of data in the form of symmetric positive definite (SPD) matrices have had notable successful applications to numerous fields including computer vision, medical imaging, and machine learning. The dominant geometric paradigm for such applications has consisted of a few Riemannian geometries associated with spectral computations that are costly at high scale and in high dimensions. We present a route to a scalable geometric framework for the analysis and processing of SPD-valued data based on the efficient computation of extreme generalized eigenvalues through the Hilbert and Thompson geometries of the semidefinite cone. We explore a particular geodesic space structure based on Thompson geometry in detail and establish several properties associated with this structure. Furthermore, we define a novel iterative mean of SPD matrices based on this geometry and prove its existence and uniqueness for a given finite collection of points. Finally, we state and prove a number of desirable properties that are satisfied by this mean.
